The system is three years ahead of schedule, but the apocalypse has never come!

Song Chaoming accepted the spear and crystal core without hesitation.

He handed the small pile of zombie crystal cores to Xiao Wu and Xiao Lu and asked them to hold it. Song Chaoming held the silver-white spear and stroked it lovingly.

This works!

This quality!

This feels!

With this silver-white spear, his metal spear made with modern technology can officially retire!

Produced by Su Shen, it must be a high-quality product!

Although Su Shen said that this spear is enough for him to use to the second level...Song Chaoming feels that with this quality and feel, he will have no problem using it to the third level!

As for hesitation or reciprocation…

Do not make jokes!

Who else in this world is qualified to repay Su Shen?

Since he gave it to himself, it was a gift! It was his honor! If he didn't hurry up and still hesitate at this time, was it because he couldn't save his insignificant face, or because he thought he was living too easy?

After handing the metal spear and zombie crystal core to Song Chaoming, Yin Bai pondered for a moment.

Then.

He expanded his own perception field, and also expanded the thick earth field derived from the rock superpower after advancing to the fifth level.

Mental energy is consumed quickly.

Heavy roars kept coming.

In just a few seconds, a circular rock barrier with a radius of about two kilometers, centered on Song Chaoming's stronghold, rose up in the city!

The circular barrier is made entirely of compressed rock.

About twenty meters high. (about seven stories high)

About ten meters thick.

There are also layers of stairs facing the side of the stronghold.

Although the defensive power of this barrier made of compressed rocks is not as good as the special alloy produced by the Red Queen, it can still resist zombies of the third or even fourth level below.

With this circle of rock barriers, as long as the zombies inside the barrier are cleared... this circular area with a radius of two kilometers with the stronghold as the center will be a safe zone. "217" has endless magical uses, whether it is used to house survivors or to defend against zombies.

in this way.

Even if Su Bai cannot stay in Linjiang City forever, with this circle of barriers as support and protection, the difficulty of the subsequent rescue by Song Chaoming and others and the difficulty of fighting zombies and zombies will be greatly reduced!

With one finger, he clicked on the center of Song Chaoming's eyebrows, pouring all the relevant information into Song Chaoming's mind, including the existence of the circular barrier and the several entry and exit passages he had reserved.

Su Baicai said: "The premise for the rescue corps to fulfill its mission is to be strong enough. In subsequent rescues, priority should be given to improving the strength of the rescue corps."

“Rescue when it’s time to rescue, and never be soft-hearted when it’s time to be cruel!”

Leaving behind his last advice, Su Bai's figure gradually faded away, and Song Chaoming and Na Jishi disappeared from sight.

"Captain, wake up."

"Su Shen has left."

Su Bai has left.

Seeing that his team leader was still stunned, Xiao Wu couldn't help but push him.

"Fuck!"

With a sudden jolt, Song Chaoming woke up from his sluggish state and immediately uttered a curse word: "Is this the strength of God Su? Moving mountains and reclaiming seas is nothing more than that, right?"

After receiving the information that emerged in his mind, Song Chaoming led Xiao Wu and Xiao Lu towards the stronghold in a hurry: "Quick! Return to the stronghold immediately!"

"As long as we clear out the zombies in this area, we will have an absolutely safe zone!"

"Zombies below the fourth level cannot destroy or cross..."

"Ah!"

"Compared to this, the little fortifications in our stronghold are nothing!"

A circular area with a radius of two kilometers.

Not to mention it was used to house survivors, Song Chaoming began to think about where to divide an area specifically for planting, or where to divide an area specifically for production operations!

This kind of safe and spacious space can never be compared to an overcrowded shelter!

After leaving Linjiang City, Su Bai returned to the shelter.

He handed the future sixth-level zombie queen he captured to the Red Queen along with the remaining zombie crystal cores, and asked her to conduct targeted research.

The research on zombie crystal nuclei is very simple. It is to find ways to process and purify the energy contained in the crystal nuclei to maximize the utilization of the crystal nuclei.

If one only uses mental power to draw the energy essence in the zombie crystal core, a survivor can only utilize 30% of the zombie crystal core.

Even if preliminary treatment and purification are carried out with supernatural powers or other means... the majority of survivors can't utilize the zombie crystal cores at 60%.

A large part of the energy essence was wasted in this way.

The red queen is different.

With her research capabilities and the complete equipment of the research center, she dare not say that it is no problem to increase the utilization rate of zombie crystal cores from 100% to over 90%!

Just the increase in utilization rate is equivalent to doubling the number of zombie crystal cores obtained out of thin air!

If you are facing a first-order zombie crystal core, which is destined to be a mess in the future, this improvement is of course not meaningful; but if you are facing a fourth-order zombie crystal core, a fifth-order zombie crystal core, which will become scarcer in number as you go up, What about the first-level zombie crystal core or even the sixth-level zombie crystal core?

This utilization rate is extremely critical!

after all.

High-level zombie crystal cores not only mean higher-level zombies, but also represent higher-level human survivors!

Without high-level zombie crystal nuclei, it would be impossible for humans alone to evolve to a higher level!

As for the Zombie Queen...

emmm.

Su Bai himself didn't know what the Red Queen could research.

but.

A zombie queen with a rank as high as level 6 should be quite rare even in the late stages of the apocalypse, right?

Such a zombie queen with endless potential.

Even if you really can't research anything...

It is also very valuable to use as a collection.

The pile of first-level zombie crystal cores, the Red Queen began to establish a research topic as soon as she received it, preparing to analyze and study them - even ordinary superpowers can initially key zombie crystal cores, which is very important to Red Queen. Later I said it was not difficult.

As for the future zombie queen.

The Red Queen specially dug out a room on one side of the steel city, used thick alloy metal as the wall, and imprisoned him in it, and arranged for puppets to supervise and observe him at all times.

Prevent it from dying suddenly or causing any danger.

For the Red Queen, this almost unique copy of the Zombie Queen... also has extremely high collection value and research value!

Before she really researches something, she will not allow the zombie queen to die easily.

After handing all the zombie crystal cores and zombie queen to the Red Queen, Su Bai left the shelter again.

He detonated the temporary space beacon located in Li Xiangling's exclusive room, and instantly crossed a distance of more than a thousand kilometers and appeared in the magic city.

Two days later.

Li Xiangling was naturally very happy to see Su Bai again.

But Su Bai clearly noticed that Li Xiangling's face was full of fatigue, and even there were dark circles under her eyes.

Facing Su Bai's concern, Li Xiangling's heart was filled with pride.

"Su Bai, do you know?"

Somewhat excitedly, he pulled Su Bai to the top floor of the stronghold. Li Xiangling pointed to the communities and buildings outside and said: "In the past two days, we started from the outer area and rescued inward. It only took two days. Within a short period of time, tens of thousands of survivors were rescued!!”

This area is the safe area that Su Bai cleared out in an instant by perfectly combining the perception field and the vitality field.

It is naturally wisest to rescue from the outside in.

Before the zombies outside the area have spread, give priority to rescuing the survivors on the outside; when they reach the inner layer, even if they make some noise... they won't attract zombies and put them in danger. .

Naturally, tens of thousands of survivors cannot be accommodated in the stronghold.

They can't even be placed in strongholds, let alone shelters that are hidden in civil air defense projects and never see the light of day.

so.

Li Xiangling placed most of the survivors in communities and buildings around the stronghold.

-.

As long as they patrol and defend the outside, these inner survivors will be safe.

but.

Also because Su Bai cleared the zombies in this area in advance, and Li Xiangling and the soldiers of the rescue corps devoted themselves to rescuing survivors in the past two days.

They have never encountered an evolved first-level zombie so far.

Accompanying Li Xiangling around the stronghold, looking at the status of the rescuers and survivors, Su Bai also told Li Xiangling the characteristics and strengths of several first-order zombies he encountered.

Then.

When she returned to Li Xiangling's exclusive room, Su Bai held Li Xiangling's hand and said with a smile, "How about I give you a fortress?"

"I dare not say how strong it is.

"But at least until the birth of the fourth-level zombies, there should be no existence that can break through.

"fortress?"

Li Xiangling became interested: "How big is it? How many survivors can be accommodated?"

"It's big."

Su Bai smiled and said: "Judging from current standards, it should not be a problem to accommodate hundreds of thousands of survivors!"

Hundreds of thousands of survivors?

Li Xiangling's eyes widened.

She couldn't imagine the concept of a fortress that could accommodate 100,000 or 80,000 survivors without fear of being besieged by zombies below the fourth level.

To know.

Even the large-scale shelters established by the Security Bureau outside every city before the end of the world could only accommodate tens of thousands of people!

Hundreds of thousands of survivors?

Are you sure this is not a new city, but really just a fortress?

Su Bai had no explanation.

Same as last time.

He pointed at Li Xiangling's butterfly hairpin, allowing it to enter a fusion state with Li Xiangling, and then expanded the field of perception, linking Li Xiangling's mental power to his own field of perception.

Immediately afterwards.

The huge mental power began to be consumed crazily.

Under Li Xiangling's "watching"...at the edge of the area centered on the two people with a radius of 9150 (Su Bai's mental attributes have increased by 20 points in the past two days) meters...

A gray-white rock barrier with a height of 20 meters and a thickness of 10 meters, with steps on the inside, slowly rises and stands on the edge of this area!!

"this...…."

Seeing this scene, Li Xiangling was shocked...

It was even more shocking than the last time when I saw Su Bai kill hundreds of thousands of zombies in an instant!

Zombies, after all, still rely on flesh and blood.

Before the end of the world, with the technology of modern civilization, as long as these zombies are gathered together and they want to be wiped out, it is just a matter of a nuclear bomb.

...

This 20-meter-high, 10-meter-thick rock barrier winds like a gray-white dragon and surrounds the entire area...

Before the end of the world comes, to protect the power of the General Administration, it cannot be built casually!

Constructing such a rock barrier and turning this circular area with a radius of 9,150 meters into an indestructible fortress... is more difficult than creating a small mountain city.

Is it high?

Move mountains and fill seas!

This is comparable to the magical powers in Taixia myths and legends!

"Su Bai, are you really not a god in myths and legends who comes to the mortal world to overcome hardships?"

Li Xiangling's eyes were particularly complicated.

"of course not."

Su Bai chuckled and said: "It's just a fifth-level thick earth field. If you can upgrade your ice power to fifth level and develop the corresponding field, you can also do it.

certainly.

Su Bai cannot guarantee its scale and size.

This time on the rock barrier, Su Bai still used all his strength. The consumption of mental energy is even greater than the last time!

after all.

It is always easier to destroy than to build.

The rock barrier was formed, and Li Xiangling just had a hurried meal with Su Bai before leaving again.

She had a lot to do again.

She will inform all the rescue fighters and survivors in the stronghold about this news, and also organize the rescue fighters and survivors to patrol the area within the rock barrier and kill every animal.

Zombies, ensure the absolute safety of this area.

She also needs to organize members of the rescue corps to redistribute the more than 10,000 survivors who have been rescued.

With such a vast safe area, the survivors who had been rescued no longer had to crowd into a room, but all huddled near the stronghold.

She also wanted to plan an area in this area to grow crops and vegetables, so that the survivors would have something to do, so that they would not be idle all day long and cause trouble.

all in all.

After obtaining such a large safe area in vain, there are so many things Li Xiangling wants to do and has to do!

And farming seems to be an ancestral gene hidden in the bones of Tairen people.

Whether it is in heaven or on earth.

Or perhaps in this apocalyptic world, the first thing everyone thinks of after getting a safe area... seems to be farming.

Even though the shelter was packed full of supplies.

But vacuum-dehydrated vegetable slices are not as satisfying as green, fresh vegetables.

Is not it?

Seeing Li Xiangling hurriedly return to work, Su Bai just observed quietly and left again.

He also wanted to go to the Imperial City to have a look.

A rock barrier was also created for the Imperial City.

in this way.

With the existence of these unbreakable rock barriers below the fourth level, whether it is the soldiers of the rescue corps or the survivors who are rescued, the safety will be 3.6

Greatly improved.

but.

A rock barrier on the Linjiang City side, and a rock barrier on the Magic City side, Jinping exhausted Su Bai's mental power.

He exchanged three purple instant recovery potions of perfect quality and drank them, then he barely recovered his mental power and set foot on the road to the imperial city again.

A few hours later.

Su Bai returned to Linjiang City.

He didn't look very good.

Teleporting again and again, spanning thousands of kilometers, from Magic City to Imperial City, Su Bai easily found the headquarters base of the Security Bureau and met the current rescuer.

Li Dongzhen, the supreme commander of the reinforcements.

Next.

Still doing what he did in Magic City, he expanded the perception field and the vitality field, and wiped out all the zombies within a 9150-meter range centered on him, and then expanded the perception field.

Combined with the thick soil field, a 20-meter-high and 10-meter-thick rock barrier was created, leaving an unbreakable security defense circle for the imperial capital.

Finish these.

After telling Li Dongzhen that when he led the soldiers to rescue the survivors, he should not forget to dig out the zombie crystal cores from the first-order zombies and leave a temporary space beacon, Su Bai returned to Linjiang City again.

Except for the mental energy being depleted again, Su Bai's trip to the imperial capital didn't have any surprises.

The reason why he looked ugly was just because... Li Songqing was dead.

Su Bai didn't expect it.

Even if I specially sent a superpower seed to Li Songqing, he would be kind-hearted when facing me and vigorous and resolute when facing work.

The old man who almost single-handedly supported the Security Bureau's rescue plan and became the nominally and practically number one person in Taixia Kingdom... still turned into a zombie.

He saw Li Dongzhen, who was filled with guilt and was working hard to numb himself.

I also saw Old Man Li, whose body was kept well preserved by Li Dongzhen's cold air. .
