The police immediately followed Luo Cheng's guidance to this route to investigate, and Luo Cheng reflected on the progress of the entire case, he always felt that something was missing, and it seemed that the connection points of each case were very far-fetched.

Was Lee Seung-woo's motive for killing Professor Wan really just to get revenge?

If he was notified to come back, who was that person?

Wang Jieyu?

Why would she do it? Why didn't she save herself?

For this reason, Luo Cheng has reported to He Zhonghua and asked him to focus on investigating the connection between Wang Jieyu and Li Shengyu.

Just when everyone was squatting to guard Li Shengyu, news came from the other side, Wu Cheng's body was found, he died in the bamboo forest a few hundred meters away from the bamboo forest building, and was deliberately buried, and a couple accidentally found Wu Cheng's body when they went up the mountain to dig bamboo shoots.

Luo Cheng and several people divided their troops into two routes, continued to track down Li Shengyu's whereabouts all the way, and rushed back to investigate Wu Cheng later.

Wu Cheng's body was highly decomposed, the time of death was almost the same as that of the ranger, the cause of death was suffocation due to a broken spine, simply put, he was twisted off his neck, and the murderer also inserted dozens of bamboo pieces into his body after killing Wu Cheng, Wu Cheng was like a grasshopper nailed to the ground, and his death was really miserable.

The police extracted a cigarette butt in the pit, this is a cigarette that Wu Cheng often smokes, and the pit dug is also very special, this pit is slowly dug out with a small hoe, one meter wide, one meter deep, two meters long, the bottom of the pit is laid with cement bricks, the cement bricks are paved with a new layer of bamboo, and the grave is also full of bamboo chips, which does not look like a temporary burial pit, but a carefully prepared grave.

Wu Cheng lay flat in the pit, with a bamboo board on his head, and dug a simple drainage ditch around the grave, which was buried because of the wind, so that the police did not find it when they searched for the first time.

"Isn't it suicide if it's so finely arranged?" Luo Cheng couldn't help but say.

"Impossible, who can break their own neck by themselves? He committed suicide, who buried the soil? The soil just covered the corpse and was not piled up into a grave, so it is impossible for Wu Cheng to arrange for someone else to bury him before he died. Dai Lin vetoed Luo Cheng's statement.

Luo Cheng hesitated, jumped out of the grave and simply lay down, he closed his eyes and carefully felt Wu Cheng's state of mind at that time.

"This grave pit was not dug by the murderer, but Wu Cheng himself." Luo Cheng explained while saying: "When the murderer found Wu Cheng, Wu Cheng had already written a suicide note and was ready to escape, this murderer was very powerful, he killed the ranger in front of Wu Cheng and dismembered and threw it into the dog cage, Wu Cheng was frightened, he knew that he could not escape death and simply put forward a request, that is, he dug his own grave, the murderer saw Wu Cheng's suicide note and decided to agree to Wu Cheng's request, Wu Cheng dug and smoked in the pit, After the cigarette butt was dug in detail, he cut down the bamboo and carefully repaired and decorated the tomb, Wu Cheng's face maintained a mysterious smile during the whole process, he knew that this person was sent by his enemy, this enemy knew him well, all his secrets were controlled, he couldn't escape at all, because he was ready to flee because he wrote a suicide note, but he didn't expect to be found by the enemy first, the only thing Wu Cheng could do was to die with dignity. ”

After the reasoning ended, Luo Cheng got up from the dirt pit, his mind was thinking about everything at that time over and over again, thinking that he had overturned his own statement.

"This murderer is very familiar with Wu Cheng, I think things should be like this, Li Shengyu was notified to call back, and Wu Cheng was responsible for contacting Li Shengyu and arranging Li Shengyu's food, clothing, housing and transportation, specifically Lu Yan implemented, Chu Palace is their common enemy, so Lu Yan cooperated, and Li Shengyu can leave here, but Li Shengyu insisted on revenge, so Wu Cheng decided to kill Li Shengyu to eliminate the mouth, in order to prevent future troubles, but Lu Yan didn't seem to want to do this, not only did she not do this, but she also made plans and plans, The two of them forged the illusion that Li Shengyu was killed and cremated, and as for Ma Chaoxin, he was just an unlucky ghost that Lu Yan had chosen a long time ago. Lu Yan thought that she could win Li Shengyu's heart, but she didn't expect Li Shengyu to kill her, Li Shengyu is a killer, and he will never allow any risks around him. ”

Luo Cheng's brain was spinning rapidly, relying only on some broken chains of evidence to connect the entire case.

"But there is a loophole in your statement, the time of death of Hu Yanglin and Lu Yan is almost the same, how can Li Shengyu kill two people in two different places at the same time?" Dai Lin pointed out the biggest contradiction in Luo Cheng's reasoning.

"The one who killed the ranger should be Wu Cheng, with Wu Cheng's dark character, he can't do anything, Lu Yan told him that Li Shengyu is dead, so he is also ready to run away, and plans to let the dog eat the ranger before coming to dispose of the body, but I didn't expect Li Shengyu to come to the door at this time, Li Shengyu told Wu Cheng about Lu Yan's death, and Wu Cheng realized that his plan was exposed, so he could only comply."

In Luo Cheng's opinion, this is the only reasoning that can make sense so far.

Dai Lin picked up the bamboo board and said to the sun, "I think I found the epitaph." ”

Under the sunlight, the small characters engraved on the back of the bamboo board slowly appeared, Wu Cheng's epitaph is a whole preface to the Tengwang Pavilion, it can be seen that Wu Cheng is a very cultivated and ambitious person, he is dissatisfied with his life, thinking that he has no talent, as the text says, Feng Tang Yi Lao Li Guang is difficult to seal.

Luo Cheng also leaned up and looked at it carefully, at first glance, there was nothing special about this epitaph, and then he found clues, some words seemed to be deliberately carved deeper, and it looked much more obvious than ordinary words, and these profound words were now a number when the epitaph was taken a little farther: 213.

What Does 213 Mean?

Wu Cheng obviously did this on purpose, so there must be some point.

"He wrote this number to guide us to something, like a lockbox or something?" Dai Lin said.

Luo Cheng nodded and agreed with this statement, Wu Cheng is by no means the kind of person who is willing to sit still, even if he wants to die, he will fight to the death, at that time he was coerced and couldn't say it clearly, so he could only use this way.

The two of them immediately returned to the small building in Wucheng, and the things in the house had been checked by the police, and there was no lockbox.

Walking in the bamboo-paved room, the bamboo under his feet creaked, Luo Cheng glanced down, seemed to think of something, and immediately pushed to the door, and then lay on the ground and began to count the bamboos on the ground.

Dai Lin also understood, Luo Cheng suspected that the so-called 213 was the second hundred and thirteenth bamboo, and he also ran to the door and counted the bamboos on the wall.

Counting to the two hundred and thirteenth, Luo Cheng groped carefully, and just as he was about to remove the bamboo, Dai Lin shouted.

"Found it!"

Dai Lin found the 213th bamboo on the wall made of bamboo, one of the bamboo knots was chiseled to make a dark grid, and a mobile phone was placed inside the bamboo!

Dai Lin took out the phone, plugged it in and turned it on.

Open your phone's address book, and a familiar name pops up in front of you.

Wang Jieyu!

Luo Cheng is clear about Wang Jieyu's number, this is Wang Jieyu's number.

There is also a video in the album, and Dai Lin clicked on the video to increase the volume.
