End of the World: My Items Can Be Upgraded Infinitely

Lin Feng completed the awakening upgrade very quickly. It might be the second-level enhancement, which did not have a qualitative change like the previous upgrade from an enhanced person to an awakener.

The upgrade that was originally expected to take five hours to complete only took three hours to complete.

It was close to five o'clock at this moment.

The defenders were also taking turns to eat and rest.

Lin Feng raised the wine glass on the table and clinked glasses with the beauty in front of him to celebrate.

Chen Yanyan opened a bottle of low-alcohol red wine. This alcohol content had no effect on the awakener.

The two raised their glasses and drank together to celebrate this wonderful moment.

Then Lin Feng began to feast on the delicious food on the table.

The awakening upgrade and enhancement consumed most of the body's stored energy.

At this moment, he not only digested and absorbed the previous food, but also the subcutaneous fat around his waist and hips was completely decomposed.

The suppressed hunger was completely released when he smelled the delicious food.

It was not until Lin Feng ate a full five dishes, equivalent to three people's individual rations, that the hunger in his body was slightly relieved.

After eating and drinking, he took out the rifle on his back and showed Chen Yanyan this rare and dangerous weapon.

There is only one orange-quality weapon and equipment at present.

With a basic damage of up to 250 and armor-breaking properties, the holder can easily deal with several tiger-backed worms.

Even if it is the large tiger-backed worm in the middle stage of the second stage, Lin Feng is now confident that he can take it down directly.

After a short rest, Li Ran's voice came from outside the house:

"Report, the deployment tonight has been completed, please inspect it, Mr. Lin."

Lin Feng opened his eyes from Chen Yanyan's arms and long legs, and realized that it was time to come out.

The so-called inspection is more to boost the morale of the guards at the outpost.

As long as he can appear at the outpost, everyone present will have an absolute sense of security and have the courage to face the more difficult battle tonight.

As Lin Feng got ready to walk out of the chariot, he saw Li Ran, Shen Jie and other commanders outside the car, and they all showed joy and expectation.

Lin Feng said nothing more, followed the crowd to the sentry post, greeted the new recruits who had lost their childishness, encouraged and praised their efforts.

From their gradually determined expressions, Lin Feng saw the maturity and stability of the veterans.

As long as they survived the Wucheng battle, they would grow into elite veterans.

And the 201st Company will also serve as Lin Feng's team, and at some point in the future, it will expand to tens of thousands of Salvation Army.

After inspecting the whole circle, Lin Feng asked the other captains to return to their posts, and then led Li Ran and Shen Jie to the center of the sentry post, the rear of the flying wing tank.

Lin Feng opened the trunk and took out the few remaining steel plates.

The standard steel plates made of fine steel were the leftovers sent by Han Yuxin. Each piece was one square meter in size, five millimeters thick, and weighed forty kilograms.

It took about one piece to build five replicas of the lv9 god-level pistol. Lin Feng spent a total of twenty pieces to equip each of the current awakened team members with a heavy machine gun.

Now, looking at the remaining ten pieces, Lin Feng decided to make a few replicas of the lv19 howitzer to deal with the increasingly fierce night offensive of the Zerg.

The shape of the outpost is a circle of circular bunkers. Even if Lin Feng goes down, he can't take care of every direction alone.

So equipping the remaining captains with lv19 howitzers is the best choice.

Although the power of the howitzer can't directly deal with the second-level tiger spine worm, as long as the distance is close enough, it can still seriously injure the opponent by hitting several shots in a row.

Slow down the Zerg's offensive pace, prevent them from destroying the fortress wall, and drag them to Lin Feng, which can temporarily solve the problem of uneven firepower distribution.

As Lin Feng stretched out his hand to cover these steel plates.

A reminder appeared in his eyes:

"Do you consume 100 kilograms of fine steel to make a lv19 howitzer?"

The replica of the lv9 god-level pistol only needs five kilograms of fine steel to complete the production. Unexpectedly, the lv19 howitzer directly doubled by twenty times.

One ton of fine steel is only enough to produce 10 howitzers.

Lin Feng frowned slightly. This huge amount of material consumption is also a costly expense.

You must know that these are all fine steel, which is different from ordinary remelted ironware. At present, the federal coastal ports have fallen, and the high-quality iron ore from abroad has been lost. The quality and quantity of domestic mines and coking steel mills have both declined...

The output of fine steel in the future will only get lower and lower.

At this moment, the finished fine steel used for weapon production has become a controlled commodity, which is more strictly controlled than food.

It is not easy to stockpile a large amount of fine steel.

At that time, it depends on whether Hu Fei and Han Yuxin can make a stable channel, otherwise Lin Feng will have to go to the steel mill in Hulao Pass and go there in person.

Find sister-in-law Yu Rou and make some concessions.

However, the steel mill is four or five hundred kilometers away from his decisive battle site, and transportation is also a big problem.

Thinking about the future acquisition of fine steel, Lin Feng has completed the synthesis of the replica with both hands.

As the red light from his hand covered the remaining ten steel plates, the next moment, their shapes changed until they became four identical large-caliber rifles.

Lin Feng's eyes moved slightly. When he copied and synthesized, he imagined the appearance of the replica as a legendary weapon that had never been mass-produced, a large-caliber shotgun nicknamed "Steam Hammer".

It is also the shotgun weapon with the highest single-shot damage in major shooting games.

Now looking at them, which are no different from those in the game, Lin Feng's mouth corners slightly raised.

When the copy synthesis was completed, the attributes of the shotgun appeared in front of him:

"Howitzer replica lv19, red quality"

"Damage 1 remaining shells 5000"

"Basic attributes: bullet recovery 1/s, space magazine 5000 spare bullets"

"Note: The effective range is within 1 km of the original. One tenth of the profit from shooting the target is fed back to the holder. It cannot cause damage to the original holder. All basic attributes are activated based on killing the target."

After reading the attributes of the replica, Lin Feng secretly breathed a sigh of relief...

As long as the bullets are automatically restored and the attributes such as the space magazine are retained, the role of the replica is still very valuable.

As for additional attributes such as the eye of death and firepower coverage, as long as there are enough replicas, they can focus on fire to achieve the same effect.

5000 rounds of spare bullets, plus a recovery speed of 3600 rounds per hour, can completely withstand the attack of the insect tide.

Four lv19 howitzer replicas can easily block and eliminate tens of thousands of black spine insects.

With them, Lin Feng can be much more relaxed.

Then, he took out two large "steam hammers" and handed them to Li Ran and the other two behind him, and introduced them at the same time:

"This is a weapon as powerful as my previous hand cannon. One shot is comparable to a 155mm howitzer. There are four of them now. You can take them to guard the other four protruding blockhouses to prevent tiger spine insects from destroying the walls of the outpost."

There are five protruding blockhouses in the bastion, which can increase the crossfire during shooting and enhance the output.

After hearing Lin Feng's introduction, Li Ran and Shen Jie took over the large-caliber steam hammer shotgun and felt the heavy weight. They were immediately excited and wanted to take it to the outpost immediately to experiment with it themselves.

Li Ran, who had already seen the unlimited bullet heavy machine gun, was the most excited. With this steam hammer shotgun, it means that there is one more super bullet awakener.

With a few more, the power is comparable to that of an artillery company.

Holding the killer weapon in his hand, Li Ran couldn't let it go and said:

"Shotgun? It's better to call it a shotgun."

Lin Feng nodded:

"Steam hammer shotgun, good, let's call it this from now on."

Then he took out the remaining two and reminded:

"It is very powerful, and the recoil is also not small."

"It weighs 100 kilograms, plus the strong push generated by continuous shooting, it is not a first-stage late awakener, and it cannot be held for a long time."

Li Ran and Shen Jie are both commanders who are on the front line. After a big battle last night, they have successfully entered the first-stage late stage by using machine guns.

Among them, Li Ran is lv17, and Shen Jie is already lv18, and is only one step away from the perfection of the first stage.

They can fully control the powerful steam hammer cannon.

Among the guards of the outpost, there are several others who have also entered the first-stage late stage, and the personnel of the holder is not a problem.

Watching the two leave in high spirits, Lin Feng immediately returned to the front of the outpost, watching the sunset in the distance, and the deep night was about to fall on the earth...

Countless Zergs began to poke their heads out of the cave.

A new round of battle is about to begin.

On the front battlefield, the main fort defenders who were worried and had not rested well all day could only rely on coffee and other substances to maintain their spirits and excitement.

The Zerg's deterrence and intimidation, and the enemy fatigue tactics have taken effect.

The defenders who had not rested well for nearly forty hours were extremely tired!

Especially during this period, half of the time was spent in arduous defensive operations. Even the awakened ones found it difficult to survive, not to mention many recruits who were only at the level of enhanced people...

The tired body and numb spirit made their combat level plummet. Whether it was aiming and shooting under the cover of night or the later ammunition supply, they were no longer as handy as last night.

Many veterans saw it and knew very well that this was a situation that no one could avoid.

At the beginning, they were also confident that these low-level Zerg from alien planets would be destroyed in an instant under the tearing of artillery fire.

But with round after round, a steady stream of Zerg swarms came to attack the defense line.

Even if the logistics and ammunition are sufficient, the flesh-and-blood humans themselves will not be able to hold on and their state will decline.

Especially tonight, there may be tiger-spine worm attacks. If anti-tank missiles and large mortars are not launched in time to block them, the wall gates of the defense line will definitely suffer heavy damage.

Once the Zerg get close, it will cause loss of life to the defenders. Even if they succeed in holding on in the end, it will only become more and more difficult to hold on.

Fortunately, the commander on the front line is not stupid. He immediately replaced the companies in the main forts on the north and south defense lines.

Let the personnel of the dozen main forts in the north who did not participate in the battle last night be replaced in the south.

As long as the Zerg are not stupid, they will definitely focus on a line of defense and attack fiercely, especially since the entrance gate has been broken in the south. With just a little more effort, several main forts can be destroyed.

Opening a gap will allow the Zerg army to press forward and launch a general attack.

On the human side, the north-south rotation of the defense line can also reduce the decline in combat power.

But what humans did was obviously more than that.

During the day, when the tiger-spine worm team kept approaching and showed their heads to shock, several secret teams hiding in the main fort launched a sniper feint attack on them.

Three super bullet awakeners took out the special bullets sent from the research institute.

A composite glue with strong adhesion to the tiger-spine worm's outer armor was injected into the bullet.

The warhead originally planned to be embedded in the carapace was directly rejected after Ding Chenghai took samples and analyzed the giant jaws of the second-level tiger-spine worm.

Because the Mohs hardness of the tiger spine worm's giant jaws is as high as a terrifying 10, which is harder than the hardest stable natural material known to humans, diamond!

Ordinary steel bullets have a Mohs hardness of only 4.5, and even the tungsten alloy of armor-piercing bullets has a hardness of only 9.5, which is impossible to pierce the tiger spine worm's biological alloy armor that is 60 to 70 mm thick.

So the research institute had to change its thinking and attach the signal transmitter to the surface of the tiger spine worm with glue. In this way, it can also be used as a beacon to explore the hiding place of the Zerg queen.

Several special bullets with adhesion ability, which serve as beacons, were used by three super bullet awakeners of the 13th Division, using the energy of awakening as a driving force, using an electronic optical surface mirror, and accurately hit the tiger spine worm two kilometers away.

They fired a total of 30 bullets, marking the 18 tiger spine worms that appeared on the battlefield.

The ping-pong-sized beacon will send a signal every two minutes to locate the tiger-spine worm swarm and where it gathers...

Now whether the first line of defense can hold is no longer a concern of the division headquarters and the federal high-level officials...

Confirming the location of the mother queen, sending strategic bombers to launch earth-penetrating fuel-air bombs remotely, destroying the brain of the Zerg, and completing the "decapitation operation" is the top priority!

And with the beacon locator, the location of the tiger-spine worm swarm is sent back one by one.

Looking at the screen, the action trajectory connected in series...

The data analysts of the institute and the surveying engineers quickly located three places where the mother queen is most likely to be.

One of them is outside the former highway toll station in the south of Wucheng, now the sentry post!
