The data for the new map is obtained from the Scout Mechanics.

Whenever Scout Robots and Micro Scouts arrive in a new area, they send key information about the area back to the base for Natasha to analyze and map.

Today, when all the satellites in the sky have failed, there is only one company in the world that can make the map so detailed.

Drawing a new map, in addition to being able to understand the distribution of zombie populations in the surrounding area, also has one advantage, that is, it plays a certain role in detection and early warning.

For example, somewhere originally a kilometer away from the safe zone, there was a group of zombies, and the number was between three hundred and five hundred.

However, one day, when the scout robot passed by there again and fed back the data to Natasha for sorting, it found that the group of zombies was missing, or the number had been greatly reduced, indicating that there must be a problem.

Either powerful mutant beasts have appeared, or a sizable human team has visited. At this time, it is time to step up vigilance and patrols.

So, in many ways, zombies have their uses.

Either to provide energy, or to act as a guard, or as a vigilance indicator.

It's up to you how you use it.

Ye Bing took a closer look at the new map.

In the last night alone, the reconnaissance team explored an area of nearly two kilometers, which exceeded Ye Bing's expectations. Presumably, this is because the miniature reconnaissance aircraft has more advantages in free terrain and will be more efficient.

It can be seen that in the security zone centered on the Doom Base, except for the dense red dot in the very center, there are no red dots displayed anywhere else.

Since only the zombies detected by the reconnaissance team will appear on the map, this map alone cannot indicate the absolute safety of the safe zone, but at least there is no need to worry about the existence of large-scale zombies inside.

Even if a few zombies existed, they would not cause trouble to the residents of the safe zone. On the one hand, his reconnaissance unit patrols every day. On the other hand, even if someone is injured, an antiviral serum can solve all the problems.

However, out of the safe zone, things are not so simple.

According to the information that has been found by the reconnaissance troops, there are no less than dozens of waves of zombies in the five blocks closest to the safe zone. Thereinto. There are only a dozen of them, and there are more than a thousand! Most of the other zombie groups blocking the main traffic arteries are more than 500.

After seeing the dense little red dots, Rao Ye Bing was mentally prepared, but he couldn't help but be surprised.

He couldn't help but complain about the density of inhabitants of the Celestial Empire.

You know, in the whole of City D, the security zone is still in the middle of nowhere, and it is still more than an hour's drive from the city center.

Even in such a place, the distribution of zombies has reached such a terrifying level. Not to mention the downtown one.

According to Ye Bing's estimate, the zombie group in the city center may be able to gather tens of thousands, hundreds of thousands. Even on normal times, every Saturday and Sunday, several business districts in the city center are crowded with people.

If all the zombies in the neighborhood run outside......

I'm afraid I can't crowd it on the streets.

Thinking of the scene of zombies crowding all over the mountains and crowds, Ye Bing couldn't help but shudder.

He secretly rejoiced in his heart: fortunately, no matter what kind of zombie has its own specific area of activity. Otherwise, if you let the hundreds of thousands of zombies in the city center forage for food. It is estimated that the humans in D City really won't last long.

Reminiscent of some American dramas I have watched before, most of the cities are deserted. Only a few main roads were full of zombies, and Ye Bing couldn't help but feel envious.

If the difficulty of survival in a country like Australia is rated as "easy", and the difficulty of the Celestial Empire such as the US imperialism is rated as "average", how can the Celestial Empire be considered a "hell" difficulty......

Ye Bing complained in his heart.

However, the good news is that zombies are still everywhere near the safe zone. But there are still some streets where the number of zombies is relatively scarce, and if you send a mechanical corps to fight steadily, you can still open up a safe passage.

With secure access, there will be more insiders coming in and out in the future. It's going to be a lot safer.

As for whether this also opens the door to convenience for outsiders...... The answer, of course, is yes. However, even if the passage is not cleared, it is inevitable that the evacuees outside will still find an opportunity to enter after knowing the safe zone.

If you want to prevent accidents, you can only find ways to effectively strengthen the defense of the security zone.

In the afternoon of the same day, Ye Bing exchanged a few more genetically enhanced injections and drove the galaxy back to the safe zone.

After another busy day, the fortifications near the residential area were quite well built, the trenches were almost dug and the main area was sealed off with barbed wire. Except for the only passage left, the other three roads leading to the residential area were basically blocked, and Ye Bing also took a detour to find it back.

When he came back, the residents' work had just ended, but there was still some time before eating, so Ye Bing walked straight to Xu Yu's gate.

However, before he could knock on the door, the people in the house opened the door as if they were already alert.

At this time, Ye Bing's hand was still in the air. He looked at Xu Yu's cold face, and forgot what to say for a while.

It was Xu Yu who was the first to ask:

"What did you bring back this time?"

Ye Bing was surprised: "Do I have to bring something back every time I come?" ”

Xu Yu said with a look of "you nonsense": "There is nothing you need in the safe zone. If you want to get something, you naturally have a way to get it outside, so there is no need to come back. ”

Hearing this, Ye Bing's first reaction was to refute, "My relatives and friends are still here, why can't I go home often", but when he thought that it was true that the interval between coming back every time was not long, it was a bit hypocritical to say that he missed his family after so many days.

Moreover, the truth is indeed as Xu Yu said, almost every time he comes back, he comes back with something.

Whether it was bringing medicine to Uncle Ji, pouring several arms and supplies to Su Cheng, or bringing Dog Dan and Ah Kang back, in short, people or things, he would never be empty in his hands every time.

Isn't that even the case this time?

Thinking of this, Ye Bing also knew that he couldn't win against him, so he simply responded:

"That's right, I came back with something this time."

As he spoke, he took out a metal box from his backpack and opened it to see that there were ten injections lined up neatly inside.

Xu Yu took the box, but he only glanced at it, and then looked deeply at Ye Bing:

"How did you get this Pure Gene Enhancement Liquid?" (To be continued.) )
