The devil's underground factory is very easy to find, and Li Feng and they found the place in less than 20 minutes after they arrived at the alley north of the bridge.

The location of the underground factory is very bad, if it weren't for the eagles who specially explored the terrain around here, it is estimated that they would still be black-eyed by now.

"Boss, the devil has a certain garrison here, we have to find a way to sneak in first."

"It's easy to get in, but it's not so simple to get into the depths of the devil's factory, and I don't know if Cai Hao's antibodies have been developed?"

Li Feng was a little worried, after all, there was a killing weapon in this factory, and that kind of biological virus was equivalent to a plague for people.

Night is the time when ghosts appear, Li Feng and the others have been waiting, and only after dark can a group of people start to act.

The devils stationed outside are not a big problem, maybe even they don't know what they are guarding are, so Li Feng easily mixed in.

Watching a team of devil patrols walk by, Li Feng rolled on a donkey and rolled into a shadow.

There are a lot of searchlights in it, and it seems that the little devil attaches great importance to this factory, otherwise there would not be so many garrisons.

It's too uncomfortable to carry some bombs on his back, and I don't know where Xiao Wen got it, he is dead on his back.

But now is not the time to complain, you have to take advantage of this time to sneak into the factory quietly.

The little devil was very clever and knew to build this factory underground, so that it would not be discovered.

So far, many people have found out that the devil has a batch of munitions here, and they don't know that there is a chemical weapons factory directly below this arsenal.

It is a pity that the devil's chemical weapons have not yet been fully developed, so they do not dare to manufacture bacteriological bombs in large quantities, but create other chemical weapons.

A chemical weapon that has not been developed with antibodies is imperfect, to put it bluntly, it has not been successfully researched, and the devils are afraid that their own people will be poisoned, so they dare not manufacture them in large quantities, let alone use these things.

Li Feng has already sensed the entrance of the underground factory, but there are many guards there, and ordinary people can't get down at all, Li Feng estimates that even the devil patrol has the right to approach.

Ma Laosan and the others also followed, and when they saw that the front was blocked, a group of people were anxious.

"It's not going to work like this, we'll have to find a way to get in."

Ma Laosan has many methods, he has been to this place before and has a certain understanding of this place.

For example, when a group of people saw some people wrapped in protective clothing in the underground research institute come out, the guards let them leave as if they didn't see it.

This made Ma Laosan see an opportunity, and a group of people quietly slipped next to these devils in protective clothing, killed them with three strokes and divided by two, and then changed into their clothes.

It's good for the devil to wear a mask, he can't see his face at all, and he believes that he can fool the devil at the door.

……

A cage in which many ragged people were kept, all of whom looked healthy but not very well.

It's been three days since the eagles came to this place, and they've been eating and drinking here all this time, but they just can't escape from this cage.

The eagle tried, and he could open the cell door, but there were a lot of guards inside, and it was a bit difficult to sneak out.

The most important thing is not this, but that he has not yet found out where Wu Mengjiao is, and he will not leave if he doesn't go back.

Looking at the researchers walking around, still holding folders in their hands, pointing at some of them from time to time, and recording something while talking, it seems that these people should be doing live experiments.

The eagle is particularly angry, you must know that most of the people here are their compatriots, and some people are different from their appearance, it seems that they should not be Chinese.

Even so, the eagle wanted to get them all out, even if it was better to kill them later than to be an experiment in it.

In this he also saw a lot of prisoners of war, most of them were from the Central Army, but also some from the New Fourth Army, and yesterday he had seen more than a dozen people go out, and then they never came back.

"These hateful devils, I will definitely kill you when I go out."

The inhumane experiments have been going on, the eagle watches the every move of these people, he can pry open the cell door at any time, but how to get out is a problem, these people have no weapons in their hands, if the devils outside pour in, then they can only serve as live targets.

However, there is one last way for the eagles to take the heads of these researchers hostage, believing that it will buy a lot of time.

But he hadn't found out where the head of the ghost researcher was, and there had never been any big names here, and even if there were a few guys who looked like big people, they were just standing on a high place and looking at the people in the cage, and if they didn't approach, they couldn't be kidnapped at all.

"I wonder how many people will survive after they get out?"

A young man in the cage said this, his tone revealing desperation, as if he had resigned himself to his fate.

There are many people who have the same feelings as him, the eagle wants to save them, but it is not appropriate to talk too much to them now, God knows if there are soft bones who betray intelligence here, yesterday I found more than a dozen guys who knelt on the ground and begged for mercy, the key is that the reason why they knelt down and begged for mercy was actually to betray their compatriots, saying that there were people in the cage who wanted to escape and plot a riot.

Those who participated in the riot were dragged away at the first time, and then they never came back, and as for those who snitched, they did not end well, and the eagle quietly killed several of them, and it was not a pity for these people to die, and it was a scourge to keep them.

Just as the eagle was thinking about it, a researcher suddenly walked up to him, this researcher was wrapped in a protective suit, he couldn't see his face clearly, and he still had a folder in his hand, and he approached the eagle's side while recording it.

Knock~Knock~Knock......

The other party knocked on the folder with a pen a few times, and suddenly the eagle's expression was shocked, and he grabbed the cage with both hands, looked at the researcher outside, the other party's eyes rolled, and then walked up with the folder in his arms.

Knock ~ Knock Knock......

As they tapped the code, the eagle's body was still moving to the side, and when it was moved to a place where there was no one, he quietly asked:

"What do you want to do?"

"Eagle, don't you know how to call us when you come out?"
