The old, cramped houses have been converted into clean operating rooms, equipped with all kinds of appliances and lighting tools, and doctors in dark green surgical gowns are ready, and the room is full of people, a large part of whom are responsible for guarding the place.

Yang Yan thought that what greeted him was an ordinary surgical operation, which was not wrong, but it was not specific enough, and when he walked into the back room, he didn't see the operating table, only a lonely chair with restraint straps, and he realized that this was a craniotomy.

The knife is not an ordinary lancet, but a special tool like a long needle to avoid destroying brain cells, the patient is only local anesthesia, the skull is cut, the brain is exposed, and always stay awake, during the operation usually have to chat, recognize pictures, answer questions, so as to avoid problems in language, logic, cognition, and memory during the operation.

The risk of brain surgery is much greater than other surgeries, brain cells will not recover, once there is a problem, it is permanent damage, Duan Zhengming did not dare to take stones for Chen Zhen is also this reason, even if he is highly skilled and does not cause any damage, the process of taking out stones will also destroy the brain, and a small wound may also cause the most serious consequences.

Yang Yan finally regained the feeling of extreme fear, but unfortunately this room is aimed at him, even if he can move for a moment, it will not help, the chair is even more terrible than the electric chair inside, the electric chair will be painful, feces and urine will flow together, and then there will be no more, and such an operation, if successful, he will no longer be himself, and it will harm many people; If you fail, you will be a waste person for the rest of your life, and you will suffer a lot of people.

It's a pity that he couldn't even protest, and someone squeezed some medicine under his tongue to prevent the effect of the operation from suddenly disappearing, Yang Yan was controlled, obediently changed into a surgical gown, sat on the chair, and tied his legs to the chair legs with restraint straps.

If he could speak, he would definitely talk to the doctor for a while, delay for a while, hoping for a miracle, miracles are usually linked to the word Chen Zhen, but this time Chen Zhen's plan was seen through by these people, and the hope seemed to be a little slim.

"Its practical darkness sweeps once, you can know that something is wrong with this place, there are so many people in a small broken room outside, there is definitely a problem, the doors and windows of this room have been modified again, they are sealed, the darkness can't come in, Chen Zhen can know that there is a problem when he explores it." Yang Yan thought so, but the darkness did not appear,

He couldn't move, someone poured some cold liquid on his head, just like he had to pour salt water on his head before electrocution, and there was no razor, because if he handed over the bald head, others would see the problem, and all that appeared was a hand drill and a bone saw.

The next step can be imagined, drill four holes in the top of the head with a hand drill, and then use a bone saw to use the four holes as angles, sawed off a rectangular skull, and pick up the "cover" to carry out the operation.

The hair is held in place by the liquid that has been smeared, leaving a coin-sized area where the hair spins are, and everything is ready to go.

With fear, Yang Yan's body trembled, not trembling with fear, but using the power of fear to fight against the power that controlled him, all he could do was to make his body tremble, the material of the restraint belt was similar to the material of the steel crossbow string, but it lacked elasticity, and he kept struggling, and with Yang Yan's strength at this time, he could pull the chair out of shape at most, and there was no way to escape.

The hand drill has been handed over to the doctor, the doctor has stood behind him, the light stone in the exposure lamp-like lighting equipment is getting brighter and brighter, an assistant has moved the light opening to the other side, this side has just been lit up, this kind of high-level surgical light needs to be operated by a person, otherwise the light will be so strong that the doctor can't see anything.

"The doctor seems to be very experienced, and he certainly won't slip his hand, at least not make a big cut on the top of my head." Yang Yan is looking for optimistic ideas, but this is not an easy task, the doctor's hand slip will only make a cut, and if the hand is not slippery, it will drill a hole, and the hand slip is better.

He could hear, see, and feel that the tip of the drill was already on his head, and the current situation, whether it was posture or situation, was very much like an execution, and the tools in the doctor's hand were to save people, but at this time, it was not much different from the dark muzzle of the gun.

Thankfully, there was movement.

There was a loud bang, the door of the room outside seemed to be broken open by an explosion, followed by shouts, there were more than a dozen people in this place, but there were only four people involved in the operation, the outside room was full of guards, the door of the transformation room was closed, and they couldn't see what was happening outside, everyone looked at the door.

Chen Zhen is here.

Yang Yan immediately judged that it was Chen Zhen who came, because the sound of fighting was continuing, these people were able to control others, at least they could make people unable to move, and the sound of fighting continued, indicating that Chen Zhen used darkness to shield the control signals of those people, and only if they were not controlled, they could continue to fight.

"That's not right!" He then wondered why he could still hear sound when darkness could prevent sound waves from transmitting. But if there is no darkness of the Chen Array, why are the people who fight not controlled?

"Phew!"

The door of the renovation room was knocked on by a hard object, and the sound was loud, but it was not knocked open, and these sounds made several people inside feel strange, but no one opened it.

"What's going on? Even if there are ten people on the other side, one person controls one, and the battle can be ended immediately, why are you still fighting? The doctor behind him asked his assistant.

No one could answer the question, and then darkness suddenly appeared, filling the room in an instant.

Yang Yan couldn't see anything, but he could still hear it, and heard his heartbeat like a drum, and then something hot was poured on his head, which made him jump violently, thinking that someone was pouring boiling water on him, thinking that his hair couldn't be saved, and it would definitely be burned off, but then he smelled thick blood.

…………

Cutting the throats of doctors, assistants, and nurses, Chen Zhen fought with the person who controlled Yang Yan in the transformation room, he broke the wall and came in, the doors and windows can be transformed in a short time, just cover them with prepared things, but it will be very troublesome to transform the walls.

He broke through the wall and came in, the person who was fighting outside was Zhou Ding, Zhou Ding would not be controlled, and the reason why there was a sound of fighting could come in was that the darkness only occupied a small half of the room, Zhou Ding stood in the dark and fought, he would not be controlled, although he couldn't see it, but he could cut desperately, and he could also pose a threat to the enemy, mainly because he could make a movement and attract the attention of these people in the transformation room, so that Chen Zhen could break the wall.

The person who controlled Yang Yan was killed, Chen Zhen cut the restraint belts on Yang Yan's hands, feet, and body, but Yang Yan still sat still, so he lifted Yang Yan up and put him at the angle between the wall and the ground to lie flat.

Pulling open the door, he rushed out and fought the men outside.

Being able to follow all the way here is related to the two explorations with darkness on the roof of the bun shop, and the other party guessed his plan, and he didn't move after the darkness was withdrawn and Xia Fan landed, but he didn't move, which is also a hint.

Yang Yan didn't move, he didn't move for a few minutes between the darkness was retracted and re-released, which was very weird, if Yang Yan was standing at the door of a clothing store, Chen Zhen would think it was a human model, but the entrance of the building is not a place to place models, and a group of people standing at the entrance of the building is also worth noting.

So Chen Zhen and Zhou Ding quietly touched the neighborhood and saw Yang Yan from a distance, but they didn't come out to rescue, because Yang Yan was following those people's actions, he should be controlled, and his actions were natural, it was his own actions, not someone was directing him to make a walking posture, if he rushed to the rescue, Yang Yan was likely to become the helper of those people, or be controlled to make self-harming actions.

Chen Zhen and the others continued to follow, all the way to this place, for fear of startling the grass and snakes, they did not release the darkness to investigate, but only determined the room they entered, and learned the layout of the room from the room downstairs.

The two acted separately, Zhou Ding waited outside the door of the house, Chen Zhen climbed to the outside of the building, used the external vibration to break the wall, and when it broke to a certain point, released the darkness to go around to the front, shrouded Zhou Ding inside, Zhou Ding hit the door, beat randomly, Chen Zhen continued to break the wall and enter the house.

Those people outside can perceive Chen Zhen or Zhou Ding in the dark, but they can't beat Chen Zhen, Chen Zhen's fighting style studied in the past year is really not good for dealing with Kong Du, five punches on the same part of Kong Du's body, it is too difficult, but how can these people compare with Kong Du, let alone five punches, with Chen Zhen's strength at this time, fifty punches is not a problem.

There were more than a dozen people outside, Zhou Ding was beaten by them for a while, it was quite miserable, but he had already strengthened, he couldn't beat the other party, and the other party couldn't beat him, as soon as Chen Zhen joined, the situation immediately changed, but he didn't know it yet, he swung his knife vigorously, and almost hit Chen Zhen several times.

After about five minutes or so, the darkness was put away, and the room was full of corpses, all of which had broken heads and mutilated bodies, Zhou Ding breathed a sigh of relief, touched his chin that was beaten, and followed Chen Zhen to the distribution room.

Yang Yan was still lying motionless, with a lot of blood on his head and body, more like corpses than those corpses outside, Zhou Ding was startled, ran over to pick him up, and saw that Yang Yan was still breathing with his eyes open, so he was relieved.

Yang Yan was excited! From the previous extreme fear, to the current relaxed, tense nerves relaxed, under normal circumstances, he should have shed tears, but he couldn't flow out, his body was still not his own, but the command, before the effect of the drug ended, he could only be a puppet.

He was carried on his back by Zhou Ding.
