The doubts contained in the criminal police question may not be fully understood, so I will explain it a little:

At that time, when Yan Muheng was knocked unconscious in the food warehouse, wasn't there a mysterious man behind him? This mysterious person smashed open the ice at the back door of the restaurant, and deliberately let Yan Muheng go to the treacherous house to report the news, that is, to inform the criminal police that the restaurant was frozen, and that Yan Muheng himself was smashed unconscious for some reason.

But no one here saw the awakened Yan Muheng really leave the food warehouse, it was just that the mysterious man felt that he had left. Is the food warehouse empty? No one has been confirmed since.

The mysterious man smashed open the ice at the back door of the restaurant and immediately headed in the direction of the treacherous house, regardless of his purpose? He was inadvertently discovered by Xie Yunmeng, who sent Xixi out and followed, and the criminal police clearly saw him entering through the gate of the treacherous house.

So Mr. Detective locked the door of the house from the outside (the key to the house had already been obtained from the survivors. Then he entered the tower through the secret passage and made peace with Minami, and then went down from the brown tower to the door of the study.

From locking the door to entering the study, Xie Yunmeng's series of actions took more than ten minutes at most.

Let's look at Yan Muheng's actions again, assuming that he was indeed knocked unconscious in the food warehouse, and after the person who knocked him unconscious left, he sneaked back to the inside of the treacherous house in order to save his life. If the above assumptions are true, then what Xie Yunmeng sees must be the suspect who stunned Yan Muheng.

In other words, the time when Yan Muheng left the food warehouse was before Xie Yunmeng sent Xixi into the restaurant, and the two of them had a high chance of meeting each other halfway, but listening to Xie Yunmeng's tone, he didn't meet anyone at all before he arrived at the restaurant.

Taking 10,000 steps back, even if it was because the wind and snow were too big, so Mr. Criminal Police and Yan Muheng didn't see each other passing by, then Yan Muheng should be the first person to return to the treacherous house.

From the previous episode, we can know that Yan Muheng entered the treacherous house and was not attacked again, he fainted on the corridor outside the living room because of fatigue, indicating that Yan Muheng also entered through the main entrance of the treacherous house.

So could it be that the mysterious person who entered later saw Yan Muheng in a coma and wanted to kill him again? But after the injured Yan Muheng entered the study to hide, why didn't he say who attacked him? Looking at Yan Muheng's appearance, it is possible that he fought with the murderer, maybe in the process of fighting, he clearly saw the appearance of the murderer, what is the reason that prevents him from telling the truth?

The above is the first guess of Yan Muheng's operation.

Next, let's look at the second guess, assuming that Yan Muheng was not knocked unconscious, he himself pretended to pass out in the food warehouse in order to avoid someone's sight, and when it was safe, it was he who smashed the ice open at the back door of the restaurant.

The suspect Xie Yunmeng found was also him, so it was easy to explain that the criminal police did not meet anyone on the way to the restaurant. Then, after Xixi entered the restaurant, the criminal police immediately followed Yan Muheng, who didn't see his face clearly, and the two of them came to the gate of the treacherous house together.

Xie Yunmeng watched Yan Muheng enter the treacherous house, then locked the door and quickly left to continue his actions.

The time was only ten minutes, in this process, Yan Muheng first fainted outside the living room door, and then got up and was attacked by a mysterious person, after a fight, the injured Yan Muheng was able to avoid the sight of everyone in the restaurant and quietly entered the study. It's already impossible to do.

And what's even more strange is that he hasn't been seen by Tang Meiya's grandson who was talking at the time, and hid in the corner of the bookshelf at the bottom of the study, until Tang Meiya's grandson took action, only to find that he was actually injured and lying there?

There is no way to make sense of this anyway, even if the sound of the fight is not heard by others, then the blood dripping from Yan Muheng's head and hands should also stay in the living room and study when he moves, but except for the place where he is leaning, there is not a drop of blood in other places, this is simply the operation method of opening the hanging, it is estimated that in addition to stealth, it is basically impossible for anyone to do it.

Therefore, when Xie Yunmeng saw Yan Muheng at this moment, he was as shocked as he saw a magician transform something incredible directly in front of his eyes! I can't imagine what happened in the ten minutes just now?

The man who was free from the shackles disguised himself and prepared to enter the living room to perform a big show in front of everyone, his facial expression was painful at the moment, and his body was deliberately stiffened into a frostbitten appearance.

The door behind him was locked, and the man realized that it might be the investigator in this house, and the investigators followed him, this thought made the man 100% vigilant in his heart, but he was not afraid, because he had a ready-made shield Yan Muheng.

Yan Muheng's existence is a guarantee that men can move freely, but the premise is that he must be able to control Yan Muheng's thinking at any time. The man grabbed his time and reached for the door to open the living room.

At this time, it was like something had struck me all of a sudden? The nerves in the man's head felt a tingling pain, especially in the temples and on the top of the head, which was almost unbearable.

'Damn it! Actually at this time...... What exactly does he want? The man crouched down, holding his head in his hands, cursing at the other half of the dark forest.

'Stay there for me, and don't come out...... I don't need you!! Trouble is dead! Get me out!! ’

Roaring in his heart, the man rubbed his black hair vigorously, hoping to drive away the pain and the irritability in his heart, but this time, the pain seemed to be unforgiving, and it could never be restored as before.

Gradually, the man's hands began to tremble uncontrollably, as if he had Parkinson's, and his nerves tightened inward, unable to stretch out.

As if struggling with something, the man stood up vigorously and waved his hand in the void, and the back of his hand accidentally rubbed against the metal piece on the door frame, and immediately several deep scratches were imprinted on the skin.

But the man did not feel the pain at all, and continued to wave as if someone was grasping his hand.

The footsteps also stepped back uncontrollably, kicking the leather shoes on the ground, and the man almost fell in the hallway. As he held his hand on the ground, his gaze stumbled upon a knife falling from somewhere.

'It's him, he wants to attack me with this knife, and I'm not going to let him do it!' The man's pupils revealed madness, and suddenly, he couldn't see anything clearly, only to feel someone grab the knife from the ground, and then there was a sharp pain in his wrist, and the top of his head hit a hard place.

As the blood flowed out, the man lost the consciousness he had just gained and fell back into the swamp wrapped in darkness......
