It is very necessary to build a giant city.

It is impossible for humans to clear out all mutant beasts in the short term, and they cannot completely surpass the strength of mutant beasts.

In this way, there is no way to maintain the status of humans and mutant beasts before the end of the world.

Building a solid city wall is undoubtedly the best way.

Mutant beasts are very strong, but they are helpless when facing walls that are dozens of meters thick and hundreds of meters high.

Unless, they have the power to destroy strength like nuclear weapons.

What's more, there will be more and more strong people among humans. As long as humans are given enough time, Xu Yi believes that humans will definitely regain the position of the overlord of the earth and stand at the top of the food chain again.

After the meeting, everyone went to have supper.

Now, the work of building an indoor greenhouse is naturally left to ordinary people.

At the same time, it is far from enough to call ordinary people in Iron City. At the same time, it is also necessary to call ordinary people controlled by Iron Hand Gang to join the construction.

However, Xu Yi doesn't need to worry about these things. It's a headache for Ling Yue and Ye Zhi. Xu Yi just set a direction.

In addition, Xu Yi also learned that the tunnel survivors arrived in the Iron City, and also knew that they had all passed Wei He's assessment and became recruits of the Seven Killing Army.

Of course, not everyone is willing to become a warrior. Some ordinary people are more willing to be an ordinary person and an ordinary laborer.

Xu Yi respects their own choices. After all, he will not force everyone to become soldiers of the Seven Killing Army. He will still give everyone the opportunity to make a free choice.

After dinner, Xu Yi and Ling Yue returned to their villa.

"Xu Yi, are you going to be ready to leave?" Ling Yue felt something and felt that Xu Yi had been arranging some things. Many things seemed a little anxious in Ling Yue's opinion.

She felt that Xu Yi was probably planning to leave the Iron City and find her parents.

He can already deal with mutated beasts of level 4. The battle is very powerful and he already has the ability to survive in the wild.

Ling Yue thought it was very understandable and reasonable at the same time.

"Well, I plan to go to Linxiang City first to see the situation and see what other cities are in. If the situation is not very good, I will retreat and leave."

"No matter what, I have to go back to my hometown. Even if they are gone, I have to confirm it myself, otherwise I will never be able to feel at ease in this life." Xu Yi said truthfully. He was indeed planning to go to Linxiang City in one or two days.

There is no need to hide these things from Ling Yue.

"Can you bring me with you?" Ling Yue asked gently against Xu Yi.

Xu Yi shook his head and said, "I am ready to move my stomach. No matter who I bring, it is not as convenient as I can move alone. You know my strength, even a mutant beast of level 4 can be killed by me."

"And, using brain beads can quickly replenish energy. As long as I am willing to use brain beads, there is no problem in saving my life. So, you don't need to worry about me, I will definitely be able to take good care of myself."

After saying that, Xu Yi hung up Ling Yue's upright nose.

He knew that Ling Yueyi wanted to wander around the world with him.

But Xu Yi didn't want to do this. First of all, Ling Yue's parents were in the Iron City, so he didn't want Ling Yue to wander around the world with him.

Secondly, Xu Yi does not want to expose his system, and he can sign in to get countless rewards.

If Ling Yue had been following Xu Yi, she would have discovered this sooner or later.

Then Ling Yue discovers it, what should she do?

Is the truth about her high school students or make up some lies to deceive Ling Yue?

Ling Yue is a very smart woman, and Xu Yi doesn't believe that she can deceive her all the time.

frank?

Don’t even think about it. Even if Xu Yi got married and had children with Ling Yue, he should not confess that he had the system and could get rewards by signing in.

After kissing for a while, Ling Yue still said worriedly: "Don't Lu Ran bring you with her? She is very fast, and she has agility and water control skills. It should be of great help to you."

"No need, she should stay. Her combat power is good. She should hunt a lot of mutant beasts for the Qikill Army and obtain a lot of brain beads." Xu Yi then refused.

At this point, Ling Yue did not continue to persuade Xu Yi.

Now, she could only trust Xu Yi, support Xu Yi, and at the same time squeeze Xu Yi dry.

Run to another city, who knows what will happen?

If Xu Yi brought another stunning girl back when he came back and said that she was Ling Yue’s sister, she would not be surprised at all.

"When will you leave?" Ling Yue wanted to know the exact time so that she would know when she would exercise with Xu Yi tonight.

"It's the day after tomorrow or the day after tomorrow. I will leave only after the 4th-level mutant wild boar meat is cooked." Xu Yi pinched Ling Yue's little face, knowing what she was planning.

"Tomorrow I will lead the team to the western suburbs to see how many mutant beasts can be hunted and try to hunt more." Xu Yi felt that it would be better to go out and hunt mutant beasts.

At the same time, let’s see if there is a chance to capture a mutated bird.

With the animal taming collar, Xu Yi has the possibility of taming the mutated birds.

With mutated birds, especially those that can be used to ride, Xu Yi can travel around the sky and quickly travel in different regions.

It was late at night that Xu Yi and Ling Yue fell asleep deeply.

The next morning, Xu Yi, who was energetic, got up early, but Ling Yue was still sleeping and had no intention of waking up.

Xu Yi had breakfast, then took 100 people away from the Iron City and headed to the suburbs.

Before leaving, Xu Yi received a miniature radar brought by the staff of the research center.

This radar is very miniature, and a small pot is only the size of an ordinary rice bowl.

However, because the battery is powerful, its detection distance has reached a distance of 20 meters.

Xu Yi first received it in his storage space and was preparing to find time to upgrade its detection distance and detection effect.

Now, he has more than 20,000 points of survival in his hands, which is because he has accumulated a long time of "save".

If there is no way to upgrade a satisfactory radar in this way, Xu Yi has no choice.

Although he now has the mutated cat Tai Chi, Tai Chi has cubs after all, and his experience is limited.

With the radar, there is an insurance.

Shortly after Xu Yi left, Ling Yue woke up.

Then, she took the remaining supernatural warriors to start cleaning the road to the suburbs.

If you want to build a wall with construction waste, it is impossible to build it near the Iron City, but you have to build it at the intersection of the suburbs and the city.

At the same time, we cannot rely solely on construction waste. We also need to rely on suburban houses. We use construction waste to turn the houses into a piece of the city and a huge wall.
