Wei Renwu was searching along the river alone, and as long as Mr. Nan Guo was dumped by the river, he would definitely be able to find clues by the river.

Sure enough, Wei Renwu walked by the river for an hour and finally found a clue.

Wei Renwu found a scratch on a stone pillar by the river, the scratch was very thin, as thin as a fishing line, so he was sure that it was drawn by a fishing line.

If the stone pillar is tied through the fishing line, that is, the murderer uses the fishing line to connect the stone pillar to Mr. Nan Guo's ankle, and then throws Mr. Nan Guo's body into the river, so that the body can be soaked in the river without being washed away by the river, until the right time, the murderer cuts the fishing line and lets the body float away.

It's just that to Wei Renwu's surprise, the first murder scene he worked so hard to find turned out to be "Wangjianglou Park".

"Wangjianglou Park" is the place where Mr. Nan Guo would come to fish every day before his death, and it is also the place where he trades for news buyers, to put it simply, this is Mr. Nan Guo's territory.

Mr. Nan Guo told Wei Renwu yesterday morning that he would retire and would leave Chengdu, which means that he would leave "Wangjianglou Park".

Wei Renwu didn't quite understand that since Mr. Nan Guo would not come back to "Wangjianglou Park", then he should have been killed by the murderer elsewhere, and then the murderer brought the body here.

Why did the murderer go to such lengths to bring people here? You must know that "Wangjianglou Park" is located in the center of Chengdu, and it is too risky for the murderer to bring a body from other places to the city center and swagger through the city, even at night.

If it weren't for the murderer who brought Mr. Nan Guo's body to "Wangjianglou Park", it means that this is the scene of the first murder, and Mr. Nan Guo was killed here.

In the end, is "Wangjianglou Park" the first murder scene?

This answer is not something that Wei Renwu can come up with, it needs to be verified by his own hands.

If this is the scene of the first murder, there will definitely be some indelible clues, such as blood.

Mr. Nan Guo was shot to death, and the gun was shot in the heart, which is where the blood is concentrated, and it is difficult to stop the blood spurting out.

Of course, after killing Mr. Nan Guo, the murderer will definitely clean up the scene and erase all the bloodstains, but after all, the murder happened at night, and the line of sight is very unclear, and after the blood flies, it is difficult for him to clean up all the bloodstains in that situation.

Wei Renwu held on to this possibility, took out a magnifying glass from his pocket, ignored the dust on the ground, lay on the ground, crawled like a puppy, and searched everywhere.

It's broad daylight now, there are countless passers-by coming and going in the park, almost every passerby who sees a man in his thirties lying on the ground like a dog on the road, will look twice, basically all passers-by regard Wei Renwu as a madman, who would do this.

However, Wei Renwu seemed to live in another world, he didn't pay attention to the eyes of passers-by at all, his eyes only had the ground and the lens under his magnifying glass, no matter how much time he spent, he must also find clues, otherwise, he would search this place piece by piece until it was proved that this was not the scene of the first murder.

It took almost two hours, and Wei Renwu's knees were numb enough to feel the pain, and Wei Renwu finally found the clue he wanted.

A very small drop of blood that has dried up, a stain that is really difficult to notice with the naked eye if it were not for a magnifying glass.

Wei Renwu noticed the shape of the blood stains, which were irregular oval, one large and the other small, from which Wei Renwu analyzed that the blood stains were formed because the blood droplets floated to the ground, and the direction in which the blood droplets floated can be inferred.

Wei Renwu estimated Mr. Nan Guo's height, and then he was able to calculate the height of Mr. Nan Guo's heart, so that the combination could calculate the distance between Mr. Nan Guo and the bloodstains, and the shape of the blood droplets on the ground could calculate the direction of Mr. Nan Guo's location, and finally determine the location of Mr. Nan Guo's shot.

Wei Renwu can basically determine where Mr. Nan Guo was shot, and he can also be sure that this is indeed the scene of the first murder.

Wei Renwu put away the magnifying glass and wanted to stand up first, but after his knees were paralyzed, he couldn't stand up at all, he sat on the ground, rubbed his hands on both knees, and rubbed his hands to increase blood circulation in his legs.

No, this is impossible, the murderer clearly wants to kill Mr. Nan Guo, and Mr. Nan Guo himself understands this, so how can the murderer threaten Mr. Nan Guo, early death and late death are death, Mr. Nan Guo has no need to obey the murderer and was forced to come here by the murderer.

If this theory is not valid, it can be proved that Mr. Nan Guo returned here voluntarily.

Why did Mr. Nan Guo come back here? He's clearly gone, and more importantly, why did the killer find here?

Wei Renwu stood up, he stroked his mustache, frowned, and thought hard, he suddenly found that this matter could not be thought from Wei Renwu's point of view, he should think from Mr. Nan Guo's point of view.

Wei Renwu not only stood in Mr. Nan Guo's point of view, he even stood in the place where Mr. Nan Guo was shot.

What made Wei Renwu have a flash of inspiration was the business card, Wei Renwu took out the business card from his pocket, this kind of business card was found from the body of Mr. Nan Guo, Mr. Nan Guo usually would not bring Wei Renwu's business card with him, even if this is a commemoration of the acquaintance of the two, he will not do this, unless it is two people who love each other very much, this situation is possible, there is no doubt that they are not this kind of relationship, otherwise it will be too disgusting, then the business card is deliberately carried by Mr. Nan Guo, in order to die after his death, Someone can go and inform Wei Renwu.

Since the business card was deliberately done by Mr. Nan Guo, that is to say, Mr. Nan Guo had predicted that he would be killed by the murderer, and he knew that he would not be able to escape, so he hoped that Wei Renwu would be able to participate in his own murder after his death.

The business card was deliberately made by Mr. Nan Guo, so this first murder scene - "Wangjianglou Park" was also intentional by Mr. Nan Guo, since he knew that he would definitely be killed, of course he could choose the place of death by himself.

Assuming that Mr. Nan Guo himself chose to die in "Wangjianglou Park", then in the same way, the murderer was also introduced to "Wangjianglou Park" by himself.

Mr. Nan Guo is a very smart person, and he must be a very smart person, because he is the one who controls all the lifeblood information of the Chengdu underground world, and a stupid person cannot do this.

So whether it was to lure the murderer to "Wangjianglou Park" or to keep Wei Renwu's business card on his body, it was carefully planned by him.

Wei Renwu now understood everything, everything Mr. Nan Guo did was not just as simple as luring the murderer here to kill, the person Mr. Nan Guo really wanted to lead here was Wei Renwu himself.

Mr. Nan Guo has been leaving a message to Wei Renwu from the beginning of the business card, guiding Wei Renwu to "Wangjianglou Park", so Wei Renwu can stand in the position where Mr. Nan Guo was killed, which is also expected by Mr. Nan Guo.

Then, Mr. Nan Guo will definitely not let Wei Renwu come here in vain, he must have left an important clue here for Wei Renwu to discover.

But what is the clue? Wei Renwu couldn't think of it for a while.

Wei Renwu silently took out a cigarette to light it, he took a deep breath of the cigarette, when Wei Renwu's mind entered a dead end, nicotine could always bring Wei Renwu out of the dead end, and this time was no exception, Wei Renwu did think of something.

Wei Renwu's location is the position where Mr. Nan Guo stood before his death, and Mr. Nan Guo was shot in the front, which means that the murderer was standing in front of Mr. Nan Guo at that time.

Wei Renwu carefully recalled that when he examined Mr. Nan Guo's body, from the holes caused by the bullets on the corpse and the location of the bullets embedded in the corpse, Wei Renwu could probably estimate the location of the murderer.

When the murderer shot Mr. Nan Guo, it was already very dark, and his vision was definitely not too good, but the murderer accurately shot Mr. Nan Guo in the heart, which shows that the murderer will never be too far away from Mr. Nan Guo, at most five meters.

After calculation, Wei Renwu found the location where the murderer was standing at that time, and he also stood there.

That's right, Mr. Nan Guo led the murderer to this position last night, and today he led Wei Renwu to this position, hoping that Wei Renwu can find the murderer.

If so, then Mr. Nan Guo must have left the final clue in this position, and this final clue is to let Wei Renwu find the murderer.

Wei Renwu looked left and right, he felt that since Mr. Nan Guo would lead the murderer to his location, then Mr. Nan Guo must have left a final clue somewhere that could directly expose the murderer.

Sure enough, Wei Renwu found that clue.

To be honest, standing in Wei Renwu's current position, it is easy to see that clue, but the murderer will not see it, because it is night when the murderer is standing here, and the darkness of the night always does not allow some people to see things that can be seen at a glance during the day, but fortunately, Wei Renwu is now daytime, so Wei Renwu can see it.

The final clue left by Mr. Nan Guo was in the bush, and Wei Renwu walked straight towards the bush and took down a miniature camera from a small tree.

There is no doubt that this camera was hung on a tree by Mr. Nan Guo in order to record the whole process of his own murder by the murderer.
