If you dig up a corpse at the beginning, the system will be awakened directly.

In fact, judging from the bark marks left behind, it does look like someone has climbed it. But the question now is that more than [-] years have passed. Why can the previous marks still be left? This is very thought-provoking.

"Actually, I thought of something that might be helpful to this case."

Director Xu suddenly spoke.

"That thing?" Su Hao was confused.

"I have previously closed down a processing workshop that secretly made homemade pesticides. According to the interrogation, I learned that there is a chemical that can cause marks like this, similar to fire, and the tree itself cannot repair such scars."

Originally, Su Hao thought Director Xu wanted to talk about the case, but he didn't expect that he was talking about the traces left behind. However, this undoubtedly provided a new direction.

The deceased carried such chemicals with him, and judging from the burn marks on the tree, the amount of chemicals was quite large. How he got it there is unknown.

"What kind of chemical is that?"

"Sodium hydroxide solvent." Director Xu replied: "It is also the so-called caustic soda water."

Suddenly, Su Hao felt that the idea of ​​​​the case had opened up.

Through the reconstruction of the case, he was able to determine that the murderer had been standing on the top of this tree to detect the entire crime scene, and even observed the entire police investigation.

If he had caustic soda on his body, or if he accidentally got the solvent somewhere, he would spill the solvent while climbing, causing damage to the tree.

This proves that the murderer can easily come into contact with the sodium hydroxide solvent.

Generally speaking, there are not many places where ordinary people use sodium hydroxide solvent. Generally speaking, using it mixed with water in a certain proportion can disinfect the farm, or it can also be used to clean stains in various places.

Of course, in addition to this, in some industrial places or factories, sodium hydroxide solvent can also be used to evaporate and remove some harmful objects. Therefore, as long as we focus on investigating these places, we may be able to find some things that have not been found before. things.

"Director Xu, do you think this is possible?" Su Hao immediately shared his thoughts with Director Xu, who was standing aside and observing the burn marks.

Suddenly, Director Xu's eyes brightened, and he became more and more excited as he listened. At the end, he clapped his hands and said, "Su Hao, no wonder they all say you are a genius in solving crimes. You are indeed a genius. Since we ignored it before, Having obtained such important evidence, I immediately communicated the news to Director Jin and asked them to investigate nearby factories or breeding farms."

"No." Su Hao shook his head and rejected this decision.

Director Xu did not ask why, because he knew that Su Hao must have his own reason for saying so, and he was waiting for this reason now.

Su Hao then expressed his opinion.

"More than forty years have passed, and the murderer may have left that place long ago. You have to go to the retailer of caustic soda water to find records from more than forty years ago. Generally speaking, if you want to buy this chemical, you need to record it. , especially in those days, there weren’t many places that could be disinfected with this thing.”

"Can it still be like this?" Director Xu was stunned. He didn't expect so much. Indeed, if you investigate these places now, you may not find anything. And with just the few people from the Guxi County Police Department, they have to investigate. Grow old till the end of time.

"Generally speaking, this item is a strictly controlled item, at least at that time, so I have to visit and investigate which dealers were able to sell this item forty years ago."

"understood."

Immediately afterwards, Su Hao and Director Xu conducted an investigation around the area, but because the sky was getting dark, the investigation could not continue, so they had to give up.

On the way back, the two also analyzed the current situation.

Because this case is an unsolved case, there are not many police forces that can be invested in it. Especially in Guxi County, there is a serious shortage of manpower. Therefore, Director Xu finally decided to set up a special team and send people directly from the provincial department to investigate.

The reason why he didn't do this before was because there was no evidence. Now that the evidence and inferences are available, he can naturally enter the application process. As long as he signs and approves, the provincial department can naturally send a task force to Guxi County to investigate.

At this time, his position as director of the provincial department provided him with great convenience.

When he returned to the police station, it was already seven o'clock in the evening. Due to Director Xu's sudden arrival, Director Jin quickly prepared a welcome banquet, and Su Hao happened to have a meal from it.

Su Hao did not leave directly after that. After making a preliminary decision on the investigation direction of the case with Director Jin, he left Guxi County. Instead of taking the high-speed rail as expected, he rented a car and drove back directly.

After driving for more than two hundred kilometers, Su Hao had returned to Jinghai for an hour.

Just when Su Hao was thinking about going back to the villa directly, he received a call from Director He.

Director He still stayed in Jinghai because of Wang Yi's tomb, and he was very busy recently because the Provincial Museum was moving to Jinghai to merge with the local museum, so Su Hao was also curious about why the other party called him suddenly. .

Su Hao parked the car aside and answered the call.

"Su Hao, do you have time now?" Director He's voice also came from the other end of the phone.

Su Hao looked at the time on his phone. It was only [-]:[-]. He said that there must be time, and he didn't plan to go home so early. After thinking for a while, he finally chose to answer: "Yes."

"Someone is here from the National Museum and wants to see you by name. I think it would be better to ask if you have time. This time he is an academician and I can't easily refuse." Director He said.

Although Su Hao can no longer count the number of academicians he has seen with two hands, academicians are still quite powerful to ordinary people. Basically, he rarely sees a few of them, even those with the level of Director He. It's not common to have leaders like this, so Su Hao also understood why Director He would make this call to him.

"Now? Tell me a place and I'll go there. I just happened to be back in Jinghai." Su Hao said.

"Aren't you in Jinghai today?" A confused voice came from the other side.

"I went to Guangfu and met a few people." Su Hao didn't tell anyone about his trip to Guxi County because it was of no use, and since this case was going to be solved, it was better for as few people to know about it.

"The one who allows you to meet must be of a very high level. Let me guess, it's not to meet Governor Mu, right?" Director He knew that Governor Mu knew Su Hao. After all, Director He was there at that time. At the scene, that was Director He's brother, and he would tell him about this matter no matter what.

"No." Su Hao denied. Originally, he really wanted to see Governor Mu, but he didn't go because he had to solve the case later. However, the goal was achieved, and the matter of having a meal with Director Xu was also mentioned by him. Done.

"Who is that? It can't be someone from the police system, right? Let me guess, Director Xu?"

"Smart." Su Hao nodded.

"You are really outrageous. I can't think of any leader you don't know now. You even know the director of the Provincial Police Department. I have only met him a few times." Director He didn't know what to say. I haven't seen this guy for a few days, and several people have become involved in such an outrageous relationship.

"Okay, let's not talk about this for now." Su Hao didn't want to waste time. If he had gone to see the so-called academician earlier, he could go home and sleep earlier. He had been running around all day today, and to be honest, he was a little tired.

"Then come to the Municipal Museum first. I'll wait for you here." Curator He naturally knew what Su Hao wanted to say and immediately gave the location.

After hanging up the phone, Su Hao drove the rented car towards the city museum without saying a word. Anyway, the car had a fixed parking location in every city for return, so he was not afraid of not returning it.

Ten minutes later, he had arrived at his destination. The highway was not far from the city museum, so even if he drove at a normal speed, it wouldn't take him too long. Naturally, he didn't even bother to use his skills.

After parking the car in the parking lot of the city museum, he walked into the exhibition hall with ease.

For him, it seemed that he hadn't been to the city museum for several days. The last time he came here was when he went treasure hunting in Dongshan City, and it had been a week.

Because he was busy with various things during this period, he did not even fulfill the stipulations of the original contract, which was the so-called excavation for the museum three times. Although the month has not yet come, there are only two actual excavations, so he still owes Take one shot.

Of course, there are still five days left in a month. As long as he can make one move within these five days, he can actually make up for the remaining opportunity. He originally planned to go there tomorrow to ask, but he didn't expect that he would still have the opportunity to come to the museum today. After a trip, I naturally thought of asking together.

After entering the hall, Su Hao saw Zhou Yuyan still sitting at the service desk.

When she saw Su Hao, she showed a face of surprise. Although Su Hao had already stated that he would not betray Chen Yueru, Zhou Yuyan didn't know why she still felt very happy after seeing Su Hao.

"Why do you have time to come here today?" Zhou Yuyan asked excitedly.

"I was called here by Director He." Su Hao sighed: "Why haven't you got off work yet?"

"The shift I work does not get off until twelve o'clock." Zhou Yuyan explained: "Now because the museum is expanding, the employees who work shifts have to work until twelve o'clock, which can be regarded as adding more space for the future opening of the museum. Popularity.”

"That's it." Su Hao nodded. In fact, he also

He didn't think this was strange. In the past, when the museum closed at six o'clock, he thought it was too early. Now that it is open until twelve o'clock, it is actually open during normal hours. If he really wants to make money, he must change these rules.

Of course, Su Hao is one of the biggest promoters here.

In the past, the entire Jinghai Museum only had one treasure. Basically, the visitors came here for this treasure, but just looking at such a thing would be too unsatisfying. But now since Su Hao joined After opening the museum, the number of treasures in the entire Jinghai Museum has become eight, even more than the provincial museum.

Naturally, many visitors will come here, and it is inevitable that the opening hours will be delayed, and this is the case now.

"Speaking of which, it's because of the pile of cultural relics you found that we had to work overtime. If it weren't for those cultural relics, we might have gotten off work at six o'clock." Zhou Yuyan also named Su Hao as the "culprit".

Of course, she actually said this half-jokingly, and she didn't hate working overtime. After all, she worked two shifts, but there weren't so many people helping to clean up and clean at night.

And she is the kind of person who likes to work alone. Although she doesn't mind working with several people, she feels that only working alone can stimulate her motivation, and she got used to it over time.

"Okay." Su Hao also knew that the other party did not blame him, and did not apologize. He just made a helpless expression, then spread his hands, chatted for a few more words, and walked into the staff passage towards the curator's office. .

Because he has to work at the Jinghai Museum for a long time, there is always an exclusive office for Director He, and Director He also invited him to meet there.

After arriving at the office, Su Hao knocked on the door politely, and then heard a "come in" voice from inside.

After Su Hao opened the door and went in, he saw Director He sitting on the main seat, and sitting on the sofa next to him was a man in his forties. He had slightly high cheekbones, a slim figure, and a smile on his face. After seeing Su Hao, he nodded towards him.

"Su Hao, you are here. Let me introduce you. This is Academician Zhu Xizhu. Academician Zhu, this is the Su Hao you are looking for."

Su Hao just wanted to reach out his hand, but was held tightly by the other party. He didn't know when the other party had stood up from the sofa, came to him, held his hand and said: "Academician Su, I have long admired your name. I have admired you for a long time." Daimyo."

"Academician Su?" Director He was stunned. He didn't seem to know what happened to Su Hao. Even if the director was his brother, he would naturally not tell him what happened in the barren mountain. After all, that was the purpose. Absolutely confidential.

"Academician Zhu is joking. He is just an honorary academician. How dare he bear such a title? But I am flattered that Academician Zhu came to see me specially." Su Hao waved his hand quickly, looking extra polite.

"What are you talking about? Academician Su is the leading anatomy expert in China. How can I flatter you?" Academician Zhu directly clasped his fists and said. Presumably, he was also one of the academicians who watched Su Hao's dissection of aliens, otherwise he wouldn't have done it. Will say this.

Watching the two people exchanging business bragging, Director He didn't know what to say. After thinking for a while, he decided that it would be better to let the two talk about business first, and he spoke quickly.

"Academician Zhu, don't you have something to talk to Su Hao about? Just tell him directly."
