Apocalyptic black technology battleship system

Chapter 52: Zombie Siege

November 16th.

Xia Bai spent nearly half a month, and the energy points he accumulated reached a terrifying one thousand, two hundred and thirty-two points.

This means that he can finally upgrade to a third-level battleship.

During this long period of time, Xia Bai was running out almost every day. As time went by, the risk of going out was getting bigger and bigger.

Because with the large gathering of survivors, zombies all over the city are moving in this direction. About a week ago, the military forces gathering survivors in Jiangbei also withdrew to the Bingcheng Prison survivor base. That was also This week, they were the last group of survivors gathered into the Ice City Prison Survivor Base.

In the past seven days, no new survivors have arrived.

This is also normal. The number of survivors in Ice City is limited to begin with. The number of survivors who flock to this survivor base will eventually decrease from large to small, especially after all external military forces are withdrawn, and there are a large number of zombies. Surrounding the outer circle of the survivor base, the number has exceeded 30,000 a few days ago. Such a survivor base is like a big cake exuding a charming atmosphere to those sluggish zombies. Hundreds of zombies are gathering at every moment, and this scale of zombies is enough to scare away many survivors.

However, after such a long buffer period, the defensive measures on the perimeter of the Ice City Prison have been fully constructed, and a four-meter-high wall has even been built, which is enough to keep the zombies out.

As time goes by, more and more zombies are coming from the ice city. Now there are almost waves of zombies coming in. Coupled with the gradually cold weather, now alone Survivors walking out alone are almost seeking death. It is even questionable whether they can break through the zombies surrounding the survivors' base.

At this moment, if you can stand on the wall of the Ice City Prison survivor base and look out, all you can see is a black and endless sea of ​​zombies.

The large number of survivors gathered in Ice City Prison are like a cake that constantly exudes a huge fragrance to these zombies, attracting them from all sides of the city.

Fortunately, Xia Bai had "foresight" about this. He had accumulated a thousand energy points before the zombies outside the Ice City Prison survivor base formed a large scale.

Xia Bai knew that the situation would get worse after winter.

Under the current situation, water supply and power supply are a problem, heating is even more of a problem, and the survivors cannot go out to find food, so they can only live on the food provided by the military. The food provided by the military is also limited. In the end, it can be distributed to The food for everyone can only become less and less, and the survivors in this survivor base at this moment, like Xia Bai, are only a few rich people who "have no worries about eating and drinking". When the time comes, the situation will It will get worse.

Of course, few people think about this now. Most people enjoy the safety and peace provided by the survivor base. Moreover, the military's scientific research institutions have also announced that they are developing viruses to fight zombies and fight against them. The troops from the outside have made contact, and it is only a matter of time before they are trapped here.

At the same time, the military is also mobilizing survivors to dig underground shelters.

However, Xia Bai knew that it was impossible to develop a serum that could restrain zombies, and even if they contacted external forces, it was impossible for anyone to come to their aid.

Now everyone is too busy to take care of themselves, and most of the military has suffered serious losses. Shengjing Military Region is separated from Bingcheng by an entire province. It is impossible for them to come to the northernmost point of China. Even if they come, it will be difficult for them to do anything.

But facing the bad situation in the future, Xia Bai was prepared. At least nothing would happen to him. As for others, even if he wanted to, he couldn't.

Xia Bai's current plan is to upgrade his battleship to level three before December. By then, he will have the real ability to take off. As long as there is enough energy, he can avoid confronting zombies to a certain extent. Confrontation can even avoid some of the most dangerous situations.

However, the time required to upgrade from a second-level battleship to a third-level battleship is far longer than the time to upgrade from the first level to the second level. It actually takes a full thirty-nine hours to upgrade to one level.

This is far beyond Xia Bai's imagination, and this means that when upgrading, Xia Bai needs to find a way to cover or hide his battleship.

Because his warships adhere to the theory of "special effects necessary for upgrades", the entire upgrade process is wrapped in light.

Just imagine, when Xia Bai upgraded, the entire commercial vehicle was glowing. In the densely populated Ice City Prison survivor base, this was simply telling others that there was a situation here.

However, this is not difficult

Xia Bai found Yang Chengzhi, and this guy directly found an empty truck for Xia Bai. In this way, Xia Bai could drive the commercial vehicle in and upgrade it directly.

Therefore, on November 16th, Xia Bai got up early and went downstairs to wait for Yang Chengzhi to drive the truck over. However, Yang Chengzhi unexpectedly lost his chain today. He waited like this just to wait. At night.

It is worth mentioning that today another wave of survivors poured in. With the firepower support of the military, they managed to break through the dense group of zombies surrounding the survivor base of Ice City Prison and came to the survivors. In the base, and after passing the security inspection, it was placed not far from Building Nine.

Xia Bai was squatting on the steps downstairs of Building 9, watching the convoy of survivors drive by. At this moment, he suddenly turned his head and saw Ye Xiaoqi. Sitting next to Xia Bai, she also smiled when she saw that Xia Bai had seen it, handed over a piece of chocolate and said, "Sister Bai calls you to eat."

The corner of Xia Bai's mouth twitched: "You are going to eat, why don't you give me some chocolate?"

Ye Xiaoqi showed a sweet smile.

Compared with other survivors, Xia Bai's life can be described as "moist". Not only does he have rice every day, but he also eats some meat dishes from time to time.

At that moment, Xia Bai also stood up and went upstairs to eat.

What Xia Bai didn't expect was that while he was waiting for Yang Chengzhi's truck, he waited from morning until night when the sky completely darkened, but he didn't wait.

Moreover, he didn't wait for Yang Chengzhi's car, but he waited for a huge accident.

At 18:24 on the 16th, a huge chaos suddenly broke out in the camp area on one side of the nine buildings. The survivors fled in panic and people shouted in confusion, but the meanings were mostly the same.

——Zombies appear in the survivor base!

When Xia Bai heard the news, his expression suddenly changed.

Because he remembered clearly that in his previous life, he stayed in the Ice City Prison survivor base for such a long time. There were only zombies rushing in from the outside, but no zombies appeared among the survivors at all.

And what he was sure of was that nothing should have happened on November 16th.

Xia Bai suddenly realized that the "history" in his memory might have changed!
