Finally, I know where the gap between my teammates and myself is. After all, everyone has not gotten the hint of my soul.

The villain in my heart is already listing the situation to myself, but my teammates are confused.

"It's harmful, I'll just say it straight away." Gu Chen, who didn't want to waste time, also said what was on his mind.

"The old man who disappeared yesterday, in my opinion, is not the real Zhao Shuisheng at all."

"As for the real Zhao Shuisheng, he actually died yesterday before we found him, and was fixed on the river bank."

"Because of the rising water, it was sunk in the water and was not discovered by the rescue team."

"It may be that the floods in the river surged, causing the body to gradually surface. It was discovered by Xiao Yuan and brought to Xize Town Central Primary School."

"Junior Brother Gu." Upon hearing this, Lu Weiwei immediately interrupted: "According to your statement, Zhao Shuisheng has been killed before?"

"And the murderer used the roots and branches of the tree to fix it, just to let Zhao Shuisheng be discovered at the right time, right?"

"It can be understood this way." Gu Chen sat cross-legged where he found the old man on the roof before, and said thoughtfully:

"The story of what happened was actually very clear from the time we investigated on the shore."

"Someone deliberately hung Zhao Shuisheng's body there and used tree roots as support. It was obvious that he wanted to hang Zhao Shuisheng in the water so that it would not be easily discovered."

"And the murderer is very aware of the power of this typhoon. He just used the cover of this natural disaster to make everyone ignore Zhao Shuisheng's disappearance."

"Yes." After hearing Gu Chen's words, Lu Weiwei also said righteously: "Junior brother Gu is right. Because of the severe weather, everyone was busy moving and had no time to take care of the people around them."

"Zhao Shuisheng usually lives alone at home. His disappearance will not be noticed by everyone. Maybe they will think that Zhao Shuisheng was transferred in advance."

"At this time, the murderer used the tree roots extending into the water to hold Zhao Shuisheng to death, making him unable to surface."

"In this way, when the flood rages, his body will inevitably surface with the impact of the current."

"One more thing." Gu Chen interrupted Lu Weiwei's words and said, "Have you discovered? The murderer actually knows the triangle structure very well."

"It can even be said that it is used with great proficiency."

Seeing the confused expressions on their faces, Gu Chen also asked himself: "Why do you say that? We can see from the big trees on the bank that the murderer chose this location to be a perfect place."

"I examined several traces of broken branches and restored these broken branches. I found that this triangular structure, if used to fix the corpse, actually involves a mechanical principle."

"Principle of mechanics?" Lu Weiwei didn't quite understand, so she continued to ask Gu Chen: "Why does this involve a principle of mechanics?"

"A damper?" Officer Wang pondered for two seconds and then said hesitantly: "Is it similar to the damper in a building?"

"That's more or less the truth." Gu Chen saw that Officer Wang had seen the clues and said truthfully: "I have checked the triangular structure on the shore. No matter from any angle, those tree trunks are enough to support Zhao Shuisheng.

The bodies will not be washed away."

"Using this triangular structure to continuously impact the water flow can completely play a buffering role."

"The seemingly heavy corpse is actually not worth mentioning at this moment. The pull of the branches resolved the push of the water flow. This push and pull miraculously prevented the corpse from being taken away by the flood."

"So that's it?" After hearing Gu Chen's explanation, Lu Weiwei suddenly understood.

But thinking of the three traces just discovered, Lu Weiwei was suddenly surprised again and said: "By the way, there is also the position where Junior Brother Gu is sitting now."

"Could it be possible to use the principle of triangle fixation to allow a fake Zhao Shuisheng to sit here motionless without being blown away by the typhoon?"

"Is it possible?" Officer Wang was thoughtful, but nodded and said, "It's possible, why is it impossible?"

Looking up at Gu Chen, Officer Wang also urged: "Gu Chen, according to what you said, the murderer must be a master of triangle fixation. Could the old man fixed on the roof be a dummy?

"

"That's right, Senior Brother Wang and I want to go together." Gu Chen heard Officer Wang's words and quickly explained:

"Before, I had been wondering why this old man wearing a bamboo hat and raincoat could sit on top of the old house and remain motionless on a windy and rainy day."

"You know, this is a very dangerous thing, let alone an old man."

"But when we gradually approached the old house, no matter how we called, the old man didn't respond. This is obviously not normal."

"The only possible explanation is that the old man may have heard the shouting but deliberately did not reply."

"Another possibility is that the coir raincoat sitting on top of the old house may simply be a dummy. Only dummies cannot hear the call of the real person."

"And we were wearing bamboo hats and raincoats at the time. We couldn't see each other's faces clearly, so we couldn't tell who was sitting on top at that time."

"Yes." Lu Weiwei, who was present at the time, also expressed her own opinion: "And Lao Wang, do you know? It was a windy day, and the old man wearing a raincoat and a bamboo hat remained unmoved on the windy day, but his body

But he was shaking violently."

"I didn't pay much attention to it because of the violent storm, but looking back now, it seems the quality was wrong."

"The quality is wrong?" Officer Wang was stunned and quickly asked Lu Weiwei: "You mean, the old man on the roof of the old house has an abnormal weight?"

"Yes, it's too light." Lu Weiwei said.

After all, it was stormy and it was already very difficult for a normal person to sit on the roof.

Faced with this situation, we can only struggle desperately in the wind and rain instead of waiting silently.

And if it hadn't been for the discovery of these three signs of damage, perhaps Lu Weiwei would never have thought of the term triangle fixation.

In this way, it seems that the person sitting on the roof did look like a dummy.

Gu Chen thought for two seconds, then glanced back at the middle-aged man's balcony, and couldn't help but said: "If the person who was on the roof yesterday was not a real person at all, but a fake."

"Then it can be explained clearly why the old man disappeared as soon as we arrived at the scene, and there was not even a sound of falling into the water."

"And if the old man wants to disappear from the roof, he will definitely use some other tools, such as ropes."

Pointing to the balcony of the middle-aged man's house just now, Gu Chen added: "I checked several surrounding buildings, but found that his balcony is the only one that is very suitable for this kind of sexy operation."

"If he uses the precise wheel and axle layout, he can pull the dummy back to his balcony through the rope in advance before we climb to the top of the building, thereby creating the illusion that Zhao Shuisheng has disappeared without anyone noticing."

"And as a result, coupled with the interference of the typhoon's violent wind and rain, we people became confused witnesses to Zhao Shuisheng's disappearance."

"But once this situation is established, it will become logical for Zhao Shuisheng to be found near the downstream river bank."

"In this way, Zhao Shuisheng was washed away by the flood and finally drowned in the river. His body happened to be caught on a branch next to the river bank. Finally, the body was picked up. Everything seemed to go smoothly."

"This...isn't this too scary? If this is really the case, then aren't we being set up by someone?"

Hearing what Gu Chen said, Lu Weiwei even felt like she was being used as a pawn.

Especially the various situations yesterday, coupled with today's strange situation, all these seem to be validating Gu Chen's statement.

But Lu Weiwei, who suddenly understood, reminded her again: "Junior Brother Gu, I have a way."

"Tell me about it." Gu Chen was not polite and directly extended his hand for Lu Weiwei to explain.

"Think about it, the middle-aged man yesterday appeared after we discovered that the old man was missing, so there must be something wrong with him, right?" Lu Weiwei said.

Gu Chen nodded silently: "What then?"

"Then? Then he must have withdrawn the dummy through the rope layout before we climbed onto the roof."

"In this way, he can create the illusion that the old man suddenly disappeared and may have fallen into the water."

"But while we are desperately searching, he can appear as a disaster victim and let us help him move, right?"

"Yeah." When Officer Wang saw Lu Weiwei staring at him seriously, he could only nod in agreement to express his understanding.

Following Gu Chen's previous prompts, Lu Weiwei's thinking became clearer and she blurted out:

"If that's the case, that would be great, because when we moved him, he brought a lot of bags with him, and we sent him to the temporary placement site at Xize Town Central Primary School."

"Last night, like everyone else, he spent the night at Xize Town Central Primary School."

"When the floods receded today, he returned home with everyone and started dredging work, but he ran into us."

"In that case, the dummy, including the coir raincoat and bamboo hat, is very likely still hidden in his home."

"He must not be able to handle the transfer of these items now. Let's go to his house and look for them. Maybe we can find them soon."

With a proud smile, Lu Weiwei also smiled and said: "Such a sudden attack will inevitably disrupt this man's entire plan."

"And if the items we previously inferred are found in his home and can be perfectly restored, it will mean that this man may be the murderer of Zhao Shuisheng."

Several people communicated quietly on the roof, and soon reached a consensus.

All doubts now point to this middle-aged man.

Officer Wang looked at the building on the opposite floor and couldn't help but said: "I hope we can find everything we need."

"Let's go." Gu Chen didn't want to waste too much time on the roof, so he started climbing down the wooden ladder to meet Yuan Shasha who was staying below.

Gu Chen had been unable to solve the mystery of the old man's sudden disappearance before.

But now it seems that everything can be solved.

The old man on the roof might not have existed yesterday, and the one on the roof might just be a doll dummy.

The murderer used the principle of triangle fixation to firmly fix it on the roof of the old house, and was visible to the naked eye by the rescue team.

All this seems to be a deliberate setup by the murderer, allowing the rescue team to act as his witnesses.

The cunningness of the murderer is evident.

And now the suspect who meets all the conditions is undoubtedly the middle-aged man who was rescued and transferred yesterday.

Gu Chen took the lead towards the building in the back row and went directly to the living room of the middle-aged man's house.
