On the exterior wall of Long'an base, Lin An took Liu Shiming to step on the back of the sandworm and climbed up to observe the surrounding terrain.

The college is located in a flat place. Except for a barren mountain behind, you can see the suburban highways at a glance in the other three directions.

It covers an area of ​​about 3.2 million square meters, which is equivalent to a small village.

On the earth wall, thirty-six engineering students kept calculating the data under the leadership of two awakened people, but whenever the sandworm couldn't help twisting, they would always be surprised by everyone.

The nightmare I was trampled by Lin An, and I felt gentle like a lamb, and it seemed like a dream.

Liu Shiming's face was pale. He was just an ordinary player, and his physical and psychological qualities were not good.

If Lin An had not called him up forcibly and beat him to death, he would not have dared to step on the back of the sandworm.

Since sandworms always twist their bodies habitually, Lin An needs to be mentally deterred.

Frowning slightly, the sandworms' appearance and riding comfort are too poor. Ordinary people can have nightmares for the whole night just when they see them.

If this thing hadn't been used as a construction beast, he would have slaughtered the equipment and the corpse could have been made into armor.

He looked at the black dragon on his wrist helplessly. Since the little guy released the dragon power continuously that day, he fell asleep again, but he did not enter the petrified state.

In the past few days, he has figured out the general situation of the Black Dragon.

The black dragon, who is still in a juvenile body, has to undergo at least two long periods of petrochemicals to grow into adulthood.

The required psychic energy starts at least five digits, or the mental power of 6 third-order variants can be satisfied.

If calculated based on the immediately built core supply of psychic energy, it will take about a year and a half to enter the mature stage with the full supply of 100 units of psychic energy per day alone.

During this period, Lin An was unable to practice and build a base.

Otherwise, he would do everything possible to ripen the black dragon as soon as possible if he said it.

After all, it is the legendary fourth-level royal family. In addition to the base car, the Abyss Black Dragon is his biggest trump card in the future.

Dragon Knight...

Thinking of the Black Dragon's adulthood, not mentioning its perverted strength, just being able to ride a dragon to fight is enough to be heart-wrenching.

"Mr. Lin'an, what do you mean is to build a city wall that surrounds the entire college... Longan base?"

Wang Jian, the awakened base who had just been appointed as the construction leader, carefully supported Liu Shiming, who had jumped off the back of the insect, and asked in disbelief:

"Also, the height is required to be at least 10 meters and the thickness is 24.7 meters. A gap in the defense tower is left for every 60 meters, and a shooting port and artillery placement point must be left on the top of the wall!?"

"There will be further improved and raised in the later stage, and the expected design height..."

“Over one hundred and sixty meters!!!”

Wang Jian looked like he saw a ghost and spoke quickly repeated the information he had communicated with Liu Shiming and Lin An.

When he talked about the design height of the last 160 meters, he almost fainted.

It's pitiful to see God.

He has never heard of such an exaggerated design plan in his life!

This is not a city wall, it is simply a complex of buildings made of skyscrapers!

What should I prevent?

Defense against aliens or Ultraman?

Lin An touched his nose awkwardly, and his exterior wall defense was designed by him considering the defense of the king-level enemy after the Cataclysm.

If used to defend against zombies, a 10-meter-high defense wall is indeed enough without considering the mutant.

But in the later stage, the attacking enemies are calculated in at least one million, and there will be many third-level kings.

A 10-meter city wall is no different from crossing a threshold for this kind of existence.

"First design according to this construction standard, Liu Shiming will be responsible for the final design plan at that time."

"The height of 160 meters was slowly covered in the later stage. Now it is designed according to the standard of 10-15 meters."

"The area of ​​the city wall in the early stage does not need to be that large, it only needs to wrap around the core area and the gate facing the city."

After listening to Lin An's explanation, Wang Jian's face was still ugly, and he took a deep breath and said with difficulty:

"Sir, do you know what the concept of a city wall that surrounds half a base about 10 meters high and 24 meters wide?"

"This means that we have to use at least a construction team of more than 100,000 people, hundreds of construction machinery, and more than hundreds of thousands of tons of cement steel bars..."

Detailed numbers, experienced and experienced.

As the number reported became larger and larger, even he himself couldn't say it.

Lin An just smiled and waited patiently for him to finish speaking.

Wang Jian did not deliberately contradict him or wanted to make excuses to refuse. It can be seen that he had calculated it sincerely and seriously.

For this type of person, Lin An would not think there is any problem because of their attitude.

On the contrary, I admire this kind of talent very much.

Don’t belittle the superiors and bully the subordinates, and dare to speak out about your professional field.

"Sir, I'm blunt. We will definitely not be able to complete it without a construction period of more than six years!"

It was said that it was too little for six years, and he didn't even dare to say that it was based on his current manpower. Even if those earth-type awakened people were exhausted, it would be good that they could build a earth wall.

"You don't have to worry about construction issues. Just cooperate with Liu Shiming to come up with the design plan."

No player has been exposed to the base building list yet. As long as the design plan is given, the base will automatically generate corresponding facilities.

The premise is that there is sufficient psychic energy and materials.

This is also an important reason why major forces in their previous lives wanted to obtain "safe zone tokens".

Otherwise, relying solely on manpower construction, even if the awakened person can build walls with his bare hands, he will not even be able to build basic facilities every few years.

The most important thing at this stage is to establish a defense line, after all, you will soon face the first wave of zombies siege.

Like other facilities, they can only be placed back.

Surviving is more important than anything else.

Wang Jian sighed deeply. Lord Lin An had spoken, what else could he say?

Maybe there is really some way for adults to create a "miracle"?

......

In the base, Zhang Tie was leading several awakened people to clean up the remaining zombies in the dormitory.

With his current strength, he started the raid and biting of the zombies after turning on the bear transformation. He cleared hundreds of corpses in half an hour.

The original dormitory building area will be transformed into a military camp in Lin An’s vision, and everyone will be militarized according to the class unit.

Like all ordinary players before, they slept in libraries and canteens, and the large shops like those in canteens did not last long.

According to the information provided by Huang Zheng and others, since the man and woman got together, there have been no less than a hundred cases of molestation, and there have even been two cases of rape.

In the long run, it will seriously affect the atmosphere in the safe zone.

An Jingtian led four awakened people to set up inspection offices in the government affairs building.

As an internal armed force department, many boys aroused great interest after seeing recruitment information.

Unlike the ones who imagined that awakened people assumed positions, the Supervision Office will recruit 200 ordinary survivors.

As the only position in the base that can be held by ordinary people and has the power of life and death.

All ordinary survivors are eager to get into it. Not to mention anything else, just being able to receive 1.5 times the share of food every day after joining is enough to make people jealous.

Since the daytime regulations were issued, everyone has received notice.

From tomorrow, the base will distribute food according to the daily minimum survival standard: 0.5 servings of canned meat, a small amount of fruit, and two servings of individual rations per person per day.

Want more food?

Yes, you can get it by making contribution points!

Each kill of zombies can be exchanged for 0.1 contribution points, 100 points of 1st-level mutants, 0.5 points of construction workers every day, 1 point of combat workers every day, and 0.5 points of supervisors every day.

Each contribution point can be exchanged for 3 parts of canned meat and 6 parts of individual combat rations.

It is not difficult for awakened people to obtain contribution points by killing zombies, but it is as difficult as climbing to the sky for ordinary people.

Therefore, the welfare number of the supervision position has a high contribution point and still has certain privileges.

However, the competition for two hundred people is cruel.

For a time, the Supervision Department was blocked by students in the district.

On the other hand, Wen Ya took Mo Ling and the only two awakened people to sort out the documents of the entire base.

As a logistics department, it not only has to undertake the task of managing the material allocation in the entire safety zone, but also integrates all personnel allocations.

In the office, Principal Huang Zheng led his original leadership to clean and organize the data with a flattering look on his face.

In the past, students and teachers did this kind of thing, but now it is his turn to do it, it is really painful.

But he didn't dare to show anything. As an old fox, he knew very well that if he had no effect, his fate would probably be the same as Zhang Zhicheng.
