With that, Li Hengtai sneered twice and pointed to the military tunnel behind him.

"Do you know what's in it?"

Dong Zhengbing was puzzled and looked at the metal buildings in front of him.

To tell you the truth, he stayed in Lianfeng mountain for such a long time, but he didn't come here and didn't know what he was doing.

"Hum, you don't know. I can tell you that you can't go out today anyway." Li Hengtai hummed and then said.

"I built it specially for the study of zombie virus. Now I have developed some achievements. Next, you will be sent in as a test object!"

"What! You. " You're secretly developing zombie virus!

Dong Zhengbing looked surprised and said incredulously.

"Unexpectedly, I tell you, this zombie virus is not only developed by my family, but also by the capital side. Did they carry out experiments with living people?"

Li Hengtai said indifferently.

"Living people?"

Hearing this, Dong Zhengbing immediately responded and pointed to him.

"Before, many survivors disappeared in the gathering place for no reason. Were you arrested to do experiments?"

"That's right." Li Hengtai nodded undeniably. For the success of the zombie virus experiment, during this period, Li Hengtai caught at least hundreds of survivors.

"Well, where are they now?" Dong Zhengbing asked bitterly.

"They?" Li Hengtai shook his head and sneered, "they are dead because of the failure of the experiment."

"Beast Not only Dong Zhengbing, but also Wang Yi and others could not help cursing.

In the absence of any certainty, using living people to do experiments directly is simply inhuman.

Even if Zhang Fei was injected with the extract of the Zombie's blood, it was because Zhang Fei was about to die, and Wang Yi had no way to do so.

Otherwise, how could Wang Yi give Zhang Fei the extract without knowing the effect?

However, Li Hengtai's words surprised Wang Yi.

Originally, Wang Yi thought that only Mr. Zhang and the mysterious organization who injected Han Wan'er with the extract studied the zombie virus.

But now it seems that these two forces are far from alone.

Even Lianfeng mountain, a gathering place of this scale, has begun to study zombies, so have other larger gathering places also started their own research on zombies?

This is a problem worthy of Wang Yi's careful consideration. Although Wang Yi did not hear any news about this in his previous life, he was just an ordinary head of the corpse hunting regiment in his previous life. How could he have access to such confidential matters?

On the contrary, the news about the extract has never been broken.

But Wang Yi didn't know what stage Li Hengtai had reached when he studied the extract of zombies.

Has it been developed like that mysterious organization, or is it still in the exploratory stage like Mr. Zhang?

"Brother Yi, shall we rush down now?"

Li Hu said in a low voice.

Now is the best time to rescue Dong Zhengbing. They are all at the gate of the base, and they are not alert yet.

"No, not in a hurry."

Wang Yi shook his head. Now, it's not just about saving Dong Zhengbing. Wang Yi is more interested in the research in this base.

Li Hengtai said a few words with a proud face to Dong Zhengbing, then waved his hand and let a group of soldiers enter the secret base with an angry look of Dong Zhengbing.

As for what Dong Zhengbing will do, Li Hengtai has just made it very clear.

It's used as a zombie extract.

A few hours later, Wang Yi and others, who had been lying in the snow for most of the day, finally waited until the sky was dim.

With the vigilance of the base below, there is no possibility to enter during the day. Only at night, under the cover of the night, can it enter.

"Brother Yi, the statistics have been done." Li Hu came around from a distance and said in a low voice.

"There are four observation towers on each side of the base. In about two minutes, sentries will patrol around the gathering place. If we want to get in, we can only get close to the base from here in two minutes, and then climb over the wall in front of the two towers. We should also pay attention to the light sweeping from time to time."

Li Hu's face can't help being dignified. It's too difficult to sneak in.

What's more, they don't have any weapons in their hands now, they can only have a dagger for each person, but the dagger is against the rifle, it's not just to die.

"Get ready and follow me now." Wang Yi's face is dignified of command way.

"Yes, brother Yi." Li Hu agreed to convey Wang Yi's order.

"Wait a minute." Wang Yi suddenly reached out and patted Li Hu on the shoulder.

"I mean, just the two of us." Wang Yi said.

"What? Just the two of us Li Hu couldn't help but let out a low cry.
