The cold blood then went directly into the hole, and fortunately the cold blood did not cover the hole.

So Xiao Han also quietly followed when he saw this, and then Xiao Han walked down the stairs at the entrance of the cave to the underground and found a clear tunnel.

At intervals on both sides of the tunnel, a light is illuminated, so the entire tunnel appears bright.

Of course, Xiao Han didn't appreciate the bright scenery, and then followed the footsteps of the cold-blooded people in the tunnel.

After the two of them walked to the end of the tunnel one after the other, Xiao Han found that two tunnels appeared in front of him.

Although Xiao Han didn't know which tunnel to take, he knew that he didn't hesitate to choose the tunnel on the left.

Immediately after that, the two walked into the tunnel again, and under the cold-blooded "lead", Xiao Han crossed the fork several times one after another.

In the end, I came to an empty underground space, and it seems that this cottage underground is not only a hidden mystery, but also a high safety factor.

As far as the part of the way in is concerned, if you don't know the choice of the fork, it will take a lot of effort.

Xiao Han looked at the entire underground space at this time, only to find that it was composed of caves one by one, as for what was inside the cave, Xiao Han didn't know in his heart.

Moreover, in this underground space, there are seventy or eighty mercenary groups, and it seems that the main strength of the fangs mercenary group is here.

Seeing this, Xiao Han was also shocked in his heart, fortunately they did not take a hard attack, if they attacked hard, not to mention whether they could successfully rescue the detainees.

Maybe even Xiao Han and their own safety can't be guaranteed at that time, Xiao Han thought to himself.

Since Xiao Han has arrived here at this time, there is no need to follow the cold blood, after all, Xiao Han has limited time, so it is better to observe here first.

Then Xiao Han's figure ran out, but the cold-blooded was completely ignorant of this, after all, Xiao Han was now in a state of invisibility.

Xiao Han came to a cave entrance at random, although there were two mercenaries standing at the entrance of the cave at this time, but this was nothing for Xiao Han.

Seeing the faint light in the dark hole, Xiao Han walked in directly without hesitation.

When Xiao Han saw what was in the cave entrance, a cloud of anger rose directly in his heart, because it was in the dim cave entrance.

In the mouth of the cave, an iron fence is horizontal in the depths of the hole, and inside the iron fence are people one by one!

The small space in the cave was crowded with people, some of them lying and some sitting, but they were all expressionless and dead.

It seems that these caves are the places where the population is held, Xiao Han couldn't help but think in his heart, and then Xiao Han observed the other caves again.

In the end, Xiao Han found that except for the cave that he entered with cold blood, the other nine caves were all the entrances of the prisoners.

And the number of people detained here has reached a full thousand, and Xiao Han couldn't help but be surprised when he got this number.

I didn't expect the Qin family to dare to do such a rebellious thing, this time we must completely eradicate the Qin family, Xiao Han thought angrily.

"What's in that hole where the cold blood is counted?" Xiao Han muttered to himself.

Then Xiao Han is figure flashed, and he came to the cave that the cold blood entered, and Xiao Han found that this cave was not quite the same as the rest.

I thought the hole was very bright, and there would be two mercenaries standing guard at a distance.

It seems that the things in this cave are very important, could it be the experimental instrument in the mouth of the fangs? Xiao Han thought to himself.

Xiao Han's mind came to this, and then he swaggered into the entrance of the cave, anyway, no one could see Xiao Han at this time.

Moreover, Xiao Han controlled his pace at this time, and did not make a trace of movement, so this group of mercenaries couldn't find Xiao Han at all.

Soon Xiao Han walked through the tunnel and came to a vast underground space, but he didn't expect that there would be something else, Xiao Han thought in his heart.

And this underground space is a wide road running north-south, and on both sides of the wide road are rooms one by one.

This place looks much better outside, could this be the place where Fangfang and them do experiments, Xiao Han thought to himself.

When Xiao Han just wanted to check these rooms, suddenly a cold-blooded voice came from the first room.

"Doctor, how is the experiment going?" Xiao Han could hear it, and there was a hint of respect in his cold-blooded voice at this time.

Xiao Han heard the sound and left, and then Xiao Han saw the cold-blooded figure and several people in white coats.

But Xiao Han was very sure that the group of people in white coats were not doctors, and they were mainly an old man.

And this old man is also the doctor in the mouth of the cold blood, and the cold blood is sitting opposite the doctor at this time.

"Second master, the experiment is going quite smoothly now!" said the doctor with an excited face when he heard the cold-blooded words.

"That's good, but the Doctor has bad news for you right now, we need to be transferred!" said Coldblood.

"Second master, what's going on, why are we leaving for no reason?" the doctor asked cold-blooded with a confused expression.

It seems that this doctor doesn't know about the Qin family, which is about to be finished, Xiao Han thought to himself when he heard this.

"Doctor, the Qin family has been discovered, so we must transfer the entry," Coldblood explained to the doctor.

"This ...... What should we do with the results of our experiments now?" the doctor said to Coldblood, frowning.

"Doctor, the experimental equipment must be taken away, as for the results of the experiment, let them stay here forever!" said to the doctor.

"Second master, these experimental results were made with great pain, can you take them with you?" the doctor said to Coldblood, obviously not wanting to give up the experimental results.

"Doctor, these experimenters are very unstable, so for everyone's safety, I hope you can think carefully!"

Experimenters? Could it be that they are really doing human experiments with poisonous fangs! Xiao Han thought in shock when he heard the cold-blooded words.

"In that case, we have to give up on these mutants and wait until we settle down before conducting human trials!" said the doctor with a pained expression.

"Don't worry, Doctor, we'll take some of the experimental samples with you!" Hearing the Doctor's compromise, Coldblood said with a smile.

And Xiao Han, who was in the dark at this time, couldn't wait to go out and strangle the two of them directly, because Xiao Han was now sure in his heart that they were doing human experiments with poisonous fangs.

And these imprisoned people are exactly what they call experimental samples, which are often referred to as guinea pigs......
