Wasteland: My items are infinitely upgraded

After listening to Lin Feng's description and questions, Ding Yi, who was sitting at the dining table, frowned slightly.

After thinking for a long time, she slowly opened her mouth and said:

"There are currently two ways to liquefy gas. One is to lower the temperature, because liquefaction will release heat, and cooling can achieve this. This is the same principle as air conditioning. The second is to increase the pressure, compressing the volume of the gas, which is what you just said. Bai Ye's spatial ability may be able to achieve liquefaction by compressing space."

Lin Feng frowned slightly:

"So, theoretically, is it possible to create space? Wouldn't that be the same as the storage bags in Xianxia and Xuanhuan novels, where you can carry unlimited supplies?"

Ding Yi smiled and shook her head:

"If we were still in the former universe, where mathematical theorems and physical laws still apply, then the so-called storage space you mentioned is absolutely impossible to achieve at present."

"Perhaps with the progress of cognition and technology in the future, it may be possible to achieve, but at least for now, it won't be achieved in the ability of a second-order evolver."

As she spoke, Ding Yi explained the reasons behind it to Lin Feng:

"To understand the spatial ability of Bai Ye, the leader of the Salvation Army, you must first understand what space is."

Lin Feng was stunned for a moment, somewhat puzzled:

"What is space? Isn't it a basic attribute of the universe?"

Ding Yi nodded and then shook her head:

"That's right, space is a basic attribute, encompassing everything, while time is just a concept, referring to the process of entropy increase and decay of an object or system. So, the first thing is to distinguish space from time."

"Secondly, space is essentially a carrier of energy. It is the expansion of energy that creates space. Therefore, the universe's space is not a constant quantity, but is in a state of continuous accelerated expansion with the expansion of energy."

"In the Big Bang theory, the speed of spatial expansion is even faster than the speed of light. Based on this theory, no civilization can reach the edge of the universe, because in the real universe space, the speed of light is the eternal upper limit of speed."

This period lasted at least ten hours… …

What kind of fuel tank can support such a long time?

This isn't a gas tank for cooking.

Entering the underground ruins requires using the full power of the flamethrower, spraying dozens of meters away, to burn the mutated creatures before they get close.

Even a full tank of liquid hydrogen couldn't sustain continuous burning for more than ten hours, right?

Thinking of this, Lin Feng directly asked.

Hearing this situation, Ding Yi frowned slightly.

Lin Feng was also thinking, not because he was smart and eager to learn, but because only by better understanding Bai Ye's ability can he make sufficient preparations for future actions.

Otherwise, with her unpredictable spatial ability, once a conflict arises and the Salvation Army wants to attack Lin Feng and others, they could easily suffer a big loss without understanding the situation.

The reason why Bai Ye is unwilling to explain in detail is probably because she is afraid of exposing the secrets of her own ability.

It is well known that she awakened the spatial ability, but very few people know the true function and potential of the spatial ability.

Including her use of spatial abilities to create nano-level graphene sieves, this kind of imaginative thinking and inspiration is by no means something ordinary people can touch.

Lin Feng has always been very vigilant about this kind of weird ability that is invisible and intangible.

After Ding Yi thought for a while, she asked Lin Feng to describe in detail, without missing a single detail, the entire process of the previous visit to deliver vegetables.

Sometimes the key to solving a problem is often hidden in some inadvertent details.

For Lin Feng, who is in the late stage of the first order, although the increase in intelligence is limited, his brain is much more active than during the enhancement period, and he can basically remember everything he sees.

Especially since it happened a few hours ago, Lin Feng's impression is very deep.

After he carefully recounted all of Bai Ye's performance, as well as what he saw and heard, the confusion on Ding Yi's face quickly turned into an excited realization:

"I know, the key to the spatial ability is those stainless steel thermos cups on her belt!"

Lin Feng narrowed his eyes:

"I know, that thing also stores a lot of liquid hydrogen, otherwise how could it be thrown out and become a very powerful bomb."

Lin Feng still has a deep impression of this thing.

When they were escaping from the underground shelter, standing at the entrance of the first underground level, they saw the Salvation Army leader throwing out a water cup, directly blowing up nearly a hundred mutated creatures.

The thousands of mutated creatures chasing the Salvation Army's main force, under the impact of this explosion, except for the third-order mutated king and a few second-order corrupted creatures, the tide gathered by countless monsters was immediately shattered for the most part.

The small thermos cup was even more powerful than his 150-point damage armor-piercing cannon, with a damage range exceeding 20 meters in radius!

Comparable to a 122mm heavy howitzer!

Ding Yi nodded, taking it for granted:

"That's for sure. Only hydrogen has such a high energy density. You must know that the energy density of liquid hydrogen is more than three times that of gasoline under the same unit. Even the rockets that launch into the sky use liquid oxygen and liquid hydrogen as fuel, and it is also the one with the largest specific impulse among the three mainstream methods, representing the highest efficiency."

"But as you just mentioned, even if an entire fuel tank is filled with liquid hydrogen, it is impossible to continuously spray fire at high intensity for more than ten hours, not to mention that it also needs to have a small half of the space to store liquid oxygen for combustion."

"Otherwise, where would there be so much oxygen in the sixth underground level to act as an oxidant for hydrogen combustion."

Lin Feng nodded, thoughtfully:

"So Bai Ye's spatial ability can indeed compress space, or maintain the stability of the expanded space?"

Ding Yi took a deep breath and affirmed:

"That's right! It uses the principle of the thermos cup."

Lin Feng seemed to suddenly understand, and subconsciously tapped the table with his right hand holding the chopsticks.

With a bang, a shallow pit palm print appeared directly on the iron table, scaring Chen Shanshan and Ding Yi beside him.

And the pair of stainless steel chopsticks in his hand also broke into two pieces.

"Sorry, I didn't control my strength."

A first-order late-stage evolver has a basic strength of more than six tons. Usually, you have to be careful when handling things. If you release all your strength, you are a humanoid demolition machine that can smash ordinary concrete walls with one punch.

Lin Feng, who was lost in thought, woke up and then said the key:

"Is it the vacuum layer in the thermos cup? The vacuum insulation layer meets the requirements you just said for creating space. There is no matter inside, and it acts as a carrier of energy."

Ding Yi nodded, agreeing with Lin Feng's answer:

"That's right. For Bai Ye, the thermos cup is a natural space expander. She can use the nearly 100% vacuum insulation layer inside the steel bottle, where there is no matter and can completely isolate sound."

Lin Feng nodded, and then asked with some doubts:

"Sound is a kind of energy, I know that, but the problem is that this only satisfies one point. What about the other point, the need for high-density energy? Could this be the truth about Bai Ye's spatial ability?"

"Doesn't vacuum isolate heat conduction, and there is no energy inside?"

"So Bai Ye's ability can directionally increase the energy density in a certain vacuum environment. Isn't that the same as Liu Qian's, which is also a power control ability?"

Hearing this, Ding Yi shook her head:

"Who said there is no energy in a vacuum? On the contrary, according to the scientific research progress in the Old Earth era, it indicates that there is an unimaginable amount of energy in the vacuum, called background energy, also known as vacuum zero-point energy."

"Coming from quantum fluctuations at the microscopic level, in a vacuum environment, microscopic particles will constantly be created and annihilated, and the energy released is vacuum zero-point energy."

"So Bai Ye's ability is likely to act on this phenomenon, intercepting microscopic particles to create additional space."

"That is what you call expanding storage space."

"According to the continuous working time of the flamethrower and the power of the thermos cup explosion, she can expand the space scale by at least five times."

"That is, within any vacuum environment, under the effect of her ability, the space can be expanded by more than five times."

Lin Feng's face changed slightly:

"So a one-liter thermos cup actually contains five liters of liquid hydrogen… …"

Ding Yi's expression was solemn:

"That's not right. There must be at least half of the liquid oxygen inside as an oxidizer to ensure the power of the explosion. The explosive power is calculated by the detonation speed. She may also be able to control the release rate of compressed space to control the detonation effect."

"This can be seen from the fact that she doesn't need to wear a sealed battle armor to isolate environmental pollution when entering the underground ruins. There is a transparent space around her that can isolate the inside and outside, which is the spatial ability she released."

"In addition, she can also remotely control the storage space she created, such as the floating thermos cup she showed you."

"This Salvation Army leader has developed her own spatial ability to the extreme, which is by no means comparable to ordinary evolvers."

"Liu Qian can only empower at present, while Bai Ye is directly changing the surrounding environment."

"If you are enemies with her, you must never engage in close combat, but only open up a distance of hundreds of meters for remote attacks."

As she spoke, Ding Yi looked at Chen Shanshan beside her:

"After going down, your task is to keep an eye on Bai Ye and prevent her from attacking Lin Feng."

"With your perception ability and the blinding effect, although it is not very useful against Bai Ye, it can at least buy a few seconds of reaction time to cover Lin Feng's retreat."

"As long as you can keep your distance and cooperate with Lin Feng's firepower, you can be invincible!"

Chen Shanshan nodded:

"Do you want to wear powered armor? Using low-energy mode can last for ten hours, and the reaction speed and defense effect are stronger than the battle armor."

The low-energy mode of the armor only retains the operation of the breathing filter and combat assistance system, without power assistance, and can only rely on itself to bear the weight of the armor.

Lin Feng frowned slightly and shook his head:

"No need to worry. At least on the upper three levels, and before solving the Tier 3 Aberrant, they still need my help. Only after the military machine tools are transported out will there be a chance for a fallout."

Lin Feng looked at Chen Shanshan, who had a grave expression, and continued to reassure her:

"Don't worry, even if Zheng Yanying is right and we need to stay vigilant, that's a matter for later. The armor, when fully charged, only lasts for fifty minutes, so it needs to be saved for the most critical moment."

"Before that, we can borrow the titanium alloy shield from Shen Yue."

Chen Shanshan hummed in agreement and nodded.

Taking advantage of the mealtime, a conversation cleared up doubts, and Lin Feng roughly understood Bai Ye's spatial abilities, and also formulated corresponding combat plans.

These preparations may seem a bit like worrying unnecessarily, but once a fight breaks out, they often become the key to victory for everyone.

After all, using your brain is always more useful than brute force.

Especially when the enemy is even stronger.

After eating and drinking his fill, Lin Feng led Chen Shanshan out of the Rock Horse chariot, preparing to report to the Salvation Army.

The first basement level wasn't very dangerous, so bringing Chen Shanshan along was mainly to familiarize her with the situation and practice cooperation.

At this moment, Zheng Yanying from the opposite vehicle walked over, followed by Shen Yue, who had just woken up.

"A team of three is best for group operations. Bring Shen Yue along; you were originally a group of three, and you just happen to be missing a defender. If Chen Shanshan has to take on two roles, it's easy for things to go wrong."

"Shen Yue has the power of the Holy Spring protecting her, so she doesn't need to wear heavy armor, and her reaction speed is faster."

Zheng Yanying said, pulling Shen Yue over.

This girl still had a nutrient solution in her mouth, her eyes still sleepy. She sniffed with her nose, then suddenly widened her eyes:

"Did you eat mid-stage evolved meat? Stewed horse meat?"

Lin Feng rolled his eyes at her, not paying much attention, and directly replied to Zheng Yanying:

"Is she okay? Doesn't she need to eat a lot to maintain her Berserk state?"

Shen Yue, who had specially evolved a consumption system, was practically an invincible glutton. All the food she ate would be converted into energy, stored in her body, and used to comprehensively enhance her physique.

She was practically a long-lasting Berserker with amazing abilities.

However, the price was that after overdrawing, she would be weakened for a long time.

For example, during the ten hours in the ruins this time, holding a titanium alloy shield weighing nearly a ton, Shen Yue's energy had been largely depleted.

As soon as she returned, she fell asleep.

Zheng Yanying patted Shen Yue on the shoulder:

"Don't worry, she's mostly recovered. We've prepared a concentrated version of the advanced nutrient solution. One tube has the effect of ten kilograms of late-stage evolved meat, equivalent to eating a hundred kilograms of mid-stage enhanced meat."

"It can maintain the physique enhancement effect for several hours."

Shen Yue nodded, took the shield from Zheng Yanying's hand, and easily lifted it up.

Lin Feng saw that her physical strength was fine, but the bags under her eyes were a bit swollen, probably because her spirit hadn't recovered yet. The previous experience in the ruins had been a great mental burden.

"Alright, then let's go together."

Although he didn't really want Shen Yue to join, Lin Feng knew better that this was a contingency plan needed by the Church.

Saying that they were sending Shen Yue along to protect the safety of the team was actually mainly to monitor Lin Feng and Chen Shanshan's contact with the Salvation Army.

Especially the focus of this mission, the acquisition of the Wasteland Wolf Source Crystal. Lin Feng still had two in his hands, given to him by Bai Ye, the leader of the Salvation Army.

And he hadn't mentioned this matter, nor had he handed over the Source Crystal afterwards.

Zheng Yanying was very clear about what that meant.

This was the guarantee that Lin Feng needed.

A guarantee that his teammates on the surface would be safe, a guarantee that if something happened to the two of them in the ruins, someone would come to their rescue, and also a guarantee that after completing the mission and returning to Oasis Town, they could smoothly obtain the Tier 2 Life Source.

Therefore, before everything settled down, Lin Feng would definitely keep the Wasteland Wolf Source Crystal tightly in his possession.

And the Salvation Army leader's move also easily sowed seeds of suspicion and doubt between the original exploration team, between Lin Feng and the Church.

Zheng Yanying was very clear about this, but was powerless to do anything.

The Salvation Army's intervention meant that the Church team, which originally possessed a large amount of Holy Water and Holy Spring power, no longer had the uniqueness to resist the pollution of the ruins.

They also lost the conditions to restrain Lin Feng and the others.

They could completely defect to the Salvation Army and complete this Wasteland Wolf Source collection mission.

Therefore, Zheng Yanying didn't say that she would join Lin Feng and Chen Shanshan, but instead sent the non-threatening Shen Yue to probe.

Fortunately, Lin Feng's ready agreement also allowed this undercurrent surging on the surface to be satisfactorily calmed.

Otherwise, the two teams would definitely fall out.

In the end, as long as Lin Feng completed the mission, only Zheng Yanying would be negligent, while Lin Feng's team would be able to occupy more initiative and say.

These confrontations were hidden in the two people's questions and answers.

Chen Shanshan was completely unaware, while Shen Yue, who stood beside the two, faintly felt something when she looked at Zheng Yanying, but could only obey the arrangements.

The fully armed trio left the camp and walked towards the cave not far away.

It was exactly 7:30 AM.

Lin Feng held his helmet and looked back at Shen Yue:

"There shouldn't be any major problems on the upper three levels. While holding the shield, you are responsible for observing the Aberrants fleeing nearby and providing me with the location and distance of the targets."

Shen Yue nodded:

"Understood. What about the Wasteland Wolf Source Crystal?"

Lin Feng shrugged:

"We'll talk about it when we get back to the fourth basement level. I guess there's still a fierce battle waiting for us there. Nothing should go wrong on the upper three levels. In the meantime, try to rest more and restore your mental state."

Soon, the three entered the cave and saw several Salvation Army members, also wearing sealed armor and fully armed, carrying fuel tanks and flamethrowers.

Bai Ye stood at the exit, with concentrated reflected solar beams shining on her head, illuminating most of the shelter.

Seeing Lin Feng and the others coming, she turned around and said:

"Only bringing two team members? I only left four people to provide protection, but there shouldn't be any big problems. Our people have already gone down in advance."

"After several hours of illumination, only the dark corners on the left and right sides of the first basement level remain, and there are still hundreds of Tier 1 Aberrants hiding in the wasteland, which need to be cleaned up completely."

"To prevent them from attacking the transportation team later."

"Your task is to cooperate with these four members to complete the cleanup of the first basement level. Currently, there are some dark corners, an area of two square kilometers, that need to be specially investigated."

"Can it be completed in six hours?"

Two square kilometers, converted, is two million square meters, a very heavy task.

Lin Feng estimated that he would need to clean up about 330,000 square meters of buildings, or 500 acres, per hour.

He would have to clean a large compartment every minute.

If they speed up, seven people should be able to complete it.

"No problem, but these four members don't need to protect me. These two are enough."

Lin Feng thought for a moment and replied.

Bai Ye nodded and let the four members carrying flamethrowers cooperate with Lin Feng and join the cleanup operation:

"Okay, that will speed things up a lot, and the cleanup will be more thorough."

"Now that everything is ready, let's begin. Being half an hour ahead will give us more free time."

With that said, Bai Ye stepped onto the stairs and walked into the ruins.

Lin Feng and the others followed and saw that the originally dim first basement level was now as bright as morning, covered in sunlight.

And the beam of light above directly pierced through the darkness and shot towards the entrance to the second basement level, five kilometers away.

In front of the stairway, they were setting up the second reflecting mirror to ensure that sunlight could enter the second basement level.

Walking into the dusty first basement level, Bai Ye quickly said goodbye to everyone.

She needed to go and direct the battle on the second basement level below.

The cleanup work was handed over to Lin Feng and his team, as well as her four subordinates.

Among the four, the captain had late-stage Tier 1 strength, and the remaining three, like Chen Shanshan and Shen Yue, were around mid-stage Tier 1.

But this also showed the strength of the Salvation Army, which was at least comparable to any of the five major villages in Oasis Town, and even stronger than the Li family of the strongest Farm Village.

To have their eyes on the Li family's Rock Horse breeding industry, they definitely had to have a few tricks up their sleeves.

During the subsequent cleanup operation, Lin Feng only used a rapid-fire cannon with ordinary power, 100 points of damage, which was more than enough to clean up Tier 1 Aberrants.

Mainly because they weren't wearing armor. Even with the blessing of polluted evolved cells, their flesh and blood bodies couldn't resist the power of the artillery fire.

As long as they were injured or crippled by the explosion while running away, and fell to the ground losing their ability to move, they would be directly burned to death by the Salvation Army members holding flamethrowers.

For the Salvation Army, hydrogen and oxygen collected using ionization technology, as long as there was water, were endless and cheap fuel.

And it came with its own oxidizing agent, and the calorific value was ridiculously high, making it very suitable for use in the airtight underground ruins.

In this way, with Lin Feng's cooperation, hundreds of shells were fired, successfully clearing almost all of the remaining Aberrants in the first basement level after four and a half hours.

At 12:00 PM, two hours earlier than the scheduled completion time, Lin Feng and his team returned to the surface cave.

The Salvation Army's deputy leader, Second-in-Command Ma Li, led Lin Feng to a heavily guarded truck.

From the refrigerated cabinet in the truck, she took out a long test tube, as thick as a forearm, filled with milky white fluid.

Lin Feng took the evolution agent and felt the rich Life Source within, slowly flowing, breathing heavily:

「lv18 Rock Horse Life Source, Red Quality」

「Contains rich Life Source, twice that of a level 17 evolution agent. Can evolve to level 18 after consumption」

Ma Li was very satisfied with the completion of the mission by Lin Feng and the others, and then said:

"Take it and use it quickly. It's two hours earlier than the scheduled 2:00 PM, so you have three hours of rest time because the second level hasn't been cleared yet."

"Captain Bai is leading people to clear it. On the second basement level, they encountered a Tier 3 Aberrant King. With the cooperation of the sunlight, they fought it for a while, injured it, and it eventually fled into the third basement level."

"This will help with the kill next."

"Remember to come back in three hours. Maybe we can solve it on the third basement level."

Lin Feng nodded, took the leader-level Rock Horse Source evolution agent in his hand, and returned to the camp.

To begin his own level 18 evolution!
