In one day, the zombies and mutant beasts in Baihua City have been emptied, and now, the streets on the outskirts of the city are blocked by a large number of concrete blocks and some building residues, and then the soldiers handle them to prevent the mutant beasts and zombies from rushing in.

At the same time, the city of Shirakaba also began large-scale construction.

The main thing is that tens of thousands of people are building the walls.

The city wall, a product of the era of cold weapons, is now on the agenda.

Shirakaba City is not big, it belongs to the kind of small town where the taxi starts and can run more than half the city.

However, even so, Yu Li decided to give up one-third of the area, leaving only two-thirds of the area with high-rise buildings, and protecting it with a city wall.

Around the city of Baihua, there are ready-made cement factories and brick factories, and there is no need to worry about the raw materials for the construction of the city wall.

In just one day, the city wall, which is thousands of meters long, about ten meters thick, and four or five meters high, has already taken shape.

In Shirakaba City, basically all the food is in the hands of the power.

The rest of the people, even if they have food in their hands, are not in large quantities, except for some smart people, who have made some small supermarkets.

Most of the rest of the people are in the kind of situation that begins to starve, and such people still account for the vast majority.

In this way, as long as Yu Li participates in the construction of the city wall, he will have food, and he can naturally gather a large number of laborers to help him build the city wall.

The end of the world has begun, and the elderly and children with relatively weak physiques have become zombies, and the rest, some people with diseases and people with poor physique, eighty percent of them can't withstand the mutation and become zombies.

In this way, the rest of the human beings, basically, are people who have the ability to work, and there is no need to take special care of a certain type of group.

As for the skills of building the city wall, today's China is in the midst of a large-scale construction in the country, and there are quite a few bricklayer groups.

In this way, the construction of the city wall only requires the bricklayers to pull the vertical lines horizontally and vertically, and then supervise the ordinary people to accumulate the reconciled concrete and bricks layer by layer.

If it is a particularly stupid person who also has a job, the city wall needs a deep foundation, they only need to dig the foundation according to the requirements.

The number of people is over 10,000, and what to do is very fast.

In particular, with the help of large forklifts and tower cranes being assembled, the speed of building the city wall is simply not too fast.

Moreover, when the city wall is built today, there are many factors that affect the progress, and I think that the construction speed will be at least several times higher tomorrow.

I believe that in the past few days, the speed of building the city wall will be faster and faster.

Looking at the foundation of the city wall that has been built, the city wall of White Birch City will definitely not be too short.

In a few days in a row, Shirakaba City has now officially changed its name to Shirakaba Base City.

The city walls of the base city have also been issued on a large scale, and a small section of the city wall, which has reached a height of fifty meters, has begun to be capped, making some bunkers for batteries and bunkers for soldiers to shoot.

Liu Wen's side also went out to look for zombies and mutant beasts for several days in a row.

Mutant beast Liu Wen They have met a lot, but the zombies, those first-generation zombies, are basically dead.

Of course, in the past few days, Liu Wen and the others have lived a relatively dull life, and for others, there are still a large number of mutant beasts that have died in the hands of Liu Wen and the three of them.

In Liu Wen's dimensional space, there are also two brown earth-based crystal nuclei, a red fire-based crystal nucleus, three white physique crystal nuclei, and two Wang Pin crystal nuclei used by mutant beasts.

In this kind of rare peaceful days, Liu Wen basically went to chat with Zhao Shuang when he had time, and Zhao Shuang was also very enthusiastic about Liu Wen.

"Boss, are we going out to kill mutant beasts today?"

In the morning, as soon as it was dawn, Liu Wen and the others walked out of the room.

It's not that Liu Wen and the others got up early, but the crowd outside has begun to become boiling.

Shirakaba City was reduced by one-third, and people from some surrounding towns and villages also fled one after another, causing the population density of Shirakaba City to increase dramatically.

Today, the population of Shirakaba City has reached 300,000.

And in the last days, as long as you are smart, you know that the early stage is very critical.

So, every day when it is dawn, on the streets, people will come out, in groups of three or five, to hunt zombies and mutant beasts.

There are also some business-minded people who set up stalls on the streets.

The place where Liu Wen lives is itself a relatively prosperous place, and noisy has become the norm.

Of course, Liu Wen and the others also understand that at this time in time, if they are not careful, their leading advantage may be overtaken by others, so basically, they also get up very early every day, and then go out to hunt mutant beasts and zombies.

"No, we have other things to do today!"

casually locked the roller shutter door and listened to Jiang Ziqiu's question, but Liu Wen gave an answer that surprised both Jiang Ziqiu and Liang Wenna.

"What are we going to do if we don't kill mutants and zombies? Boss, you're not going to find Zhao Shuang, are you? ”

Jiang Ziqiu was straightforward, looked at Liu Wen, and asked suspiciously with a smile on his face.

"you, am I the kind of person who doesn't get down to business?"

"We already have seventeen extra white crystal nuclei in our hands, as well as three king crystals, tens of thousands of other first-level death crystals, and many first-level and second-level beast crystals."

"These crystal nuclei will definitely depreciate over time, we might as well exchange them for something useful to us!"

"For example, special crystal nuclei of other colors, second-level mourning crystals, this kind of item that can improve our strength, this is the king, understand?"

In the past two days, Liu Wen has obtained two Wang Jing, and before in the grain depot, Liu Wen got one, adding up to three Wang Jing in Liu Wen's hand.

And Wang Jing's thing, the milk bean is already a king mutant beast, and it is useless to it.

However, in Liu Wen's mind, if he took out Wang Jing, Jiang Sanmiao or Yu Li, he would be happy to exchange with him.

"Brother Liu Wen, why didn't you take it out and trade with others earlier? Now it's the seventh day of the end of the world, and it's only been traded, and the first-level and second-level beast crystals are already rotten on the street! ”

After Liu Wen explained, Liang Wenna, who has always liked to listen quietly, couldn't help but ask curiously.

"Of course I knew it would depreciate, but Yu Li had been almost squeezed by us before."

"Jiang Sanmiao, obviously there is no special crystal nucleus in his hand, Zhang Tingting only has one earth-based one, and we have also replaced it!"

"At that time, I wanted to trade with them, but they were poor, so I had no choice but to wait!"

"Now that five days have passed, come to think of it, they should have some good things in their hands, it's time to squeeze them!"

Liang Wenna also has a high IQ, but she is still not as sensitive to business as Liu Wen.

Liu Wen's approach is very simple, before in the entire Baihua Base City, no one had spending power, and he couldn't exchange good things for good things, but it was easy to be targeted.

And now it's different, five days have passed, and all forces have surplus food in their hands, so naturally it is the best time to trade.
