"Weakness?"

The crowd was slightly stunned, and then asked Xu Shaotang excitedly, "do you mean that the weakness of these zombies is something like a small piece of stone?"

Xu Shaotang nodded and said: "if I guess correctly, it should be true. As you have seen just now, even if the head of the zombie is cut open, he will not die, but I just smash the thing, and he will lose his life immediately."

Xu Shaotang is very happy to find the weakness of zombies, which means that they don't need to break up zombies in the process of fighting with zombies in the future. They just need to smash the stone like thing in their brain.

Although it is only the size of a pea, it's really difficult to hit it accurately under the Zombie's attack, but it at least gives them a way to kill the zombie quickly. After being proficient, it's not impossible to kill the zombie.

What's more, ordinary soldiers have more ways to kill ordinary zombies. If they shoot more than ten times at the head of a zombie, there will always be one shot that can hit the key point of a zombie.

Listening to Xu Shaotang's words, people think about the reaction before and after the zombie. They all think that Xu Shaotang's guess should be eight or nine. In fact, it's very easy to confirm, that is, just go and grab some zombies to do an experiment.

"How did you find out?" Milo man looks at Xu Shaotang curiously. Xu Shaotang really gives him too many surprises. He even thinks that if Xu Shaotang comes to the northern defense line earlier, the casualties of round table riding earth regiment may be far less than the current casualties.

Xu Shaotang said with a smile: "lukar sent drones to investigate the city last night and found that the zombies seemed to be killing each other. When it was light, I had planned to go to the city to see if lukar's intelligence investigation was wrong. In the middle of the way, I met two zombies who had evolved to kill each other. This zombie killed another zombie and killed another one from another At that time, I thought it was wrong, so I grabbed this zombie and came back to do an experiment. I didn't expect that I really guessed it right. "

After this happy event, Xu Shaotang's face suddenly became serious again and said slowly: "according to my observation, this zombie's strength seems to be stronger after eating the thing in that Zombie's head."

"You mean these zombies can evolve by swallowing each other's brains?" Long Fei in the heart inexplicably jumps, subconsciously asks to Xu Shaotang.

Xu Shaotang nodded slightly and said, "it should be!"

He's not quite sure about his guess yet, but she believes it should be the same.

This matter needs to be confirmed later, just like whether the pea sized thing is the key of zombies.

Tantai Jingming frowned slightly and said with a worried face: "you said that the zombies in the center of the city are killing each other. Then, according to your guess, that is to say, those zombies in the city are now undergoing a lot of evolution in this way?"

Xu Shaotang nodded and said: "combined with the situation that the zombies suddenly retreated yesterday and the fact that these zombies killed each other, if my guess is correct, it is not difficult to see that the killing between zombies is a premeditated killing, which is probably led by the most likely Zombie King."

It's all for the sake of this. There's no need for Xu Shaotang to say more about the following.

If so, it's not good news for them.

Although mutual killing will reduce the number of zombies, there will be more powerful zombies. An evolved zombie is more difficult to deal with than ten ordinary zombies.

"There's something wrong with it!" Milo thought a little, said: "now our top priority is to confirm whether your guess is correct, if you guess is correct, we may have to take the initiative to attack the zombies."

Xu Shaotang took a look at Milo, then nodded slightly and said, "to prove that my guess is really simple, just find some zombies to test it. Well, I'll take our people to catch some zombies and come back. You'll contact Lucar immediately and ask him to prepare a place for us to test. In addition, I'll inform Joseph. If possible, they will try their best to carry out the test and confirm whether my guess is correct as soon as possible. "

Now for them, time is a bit tight. If it's true, as Xu Shaotang guessed, the more backward it is, the worse it will be for them. No one knows how far these zombies can evolve by swallowing things in their heads.

"Well, then hurry up!"

Milo also knows the seriousness of the matter, said a word to Xu Shaotang, and immediately went to talk to Lucar.

Xu Shaotang also quickly led the dragon group to the center of the city. Now they don't have to find strong zombies. They just need to find some evolved zombies and undeveloped zombies to go back and do an experiment.

They walked for a long time and didn't see any zombies. This abnormal situation made their uneasiness more intense.After a few kilometers to which research center is located, they finally saw the trace of zombies. As Xu Shaotang saw yesterday, those zombies are killing madly, but they are killing people of their own kind instead of human beings.

"Come on, everybody grab a zombie and go!" Xu Shaotang rushed to the group of zombies who were killing each other, and said to the Dragon Group: "be careful, don't turn over the boat in the sewer."

Although the strength of these zombies here doesn't seem to be too strong, the disgusting thing about zombies is that if they touch his blood, they will become zombies like him, which is a threat to them. If they accidentally touch the Zombie's blood, they won't even regret it.

People also know that these zombies are dangerous. After nodding to Xu Shaotang, they began to kill the zombies one after another.

They moved very fast. In less than three minutes, each of them had captured a zombie. In order to prevent the zombies from resisting, they learned Xu Shaotang's method one after another, paralyzed the zombies directly, and then quickly dragged the zombies back to the northern defense line.

By the time they got to the northern line, several helicopters had already stopped there, and when they saw them coming back, the helicopters started quickly.
