Kang Ran trembled and looked at Ye Chu and said: "Coach, it's not my fault, tonight Wang Haiting's son celebrated his birthday, I sent them to the hotel together, he asked me to go first, but I didn't dare to go, and then Wang Haiting received a call from the institute and asked Wang Haiting to go back, when we came to the intersection, a bus crashed over, and I immediately dodged, but Wang Haiting, who was sitting in the back, didn't tie a safety agent, so he ......!"

Ye Chu patted Kang Ran's shoulder, expressed comfort, and said encouragingly: "You have done a good job. Li Zhi stepped forward and said: "At that time, I was following behind, and after the car accident, I saw that Wang Haiting had been rescued from the car by Kang Ran, so I went to arrest the bus driver who caused the accident, but I found that there was no one driving in the car at all, and there were no suspicious people when I looked around." ”

At this time, from the corridor of the hospital, there was a sound of high-heeled shoes, and Kang Ran said, "This is Wang Haiting's wife." ”

And behind Wang Haiting's wife, followed by Chu Yan'er, after all, Wang Haiting is an employee of Shenghong Group.

Ye Chu nodded, and immediately issued an order, let Kang Ran continue to stay here, the relationship between Li Zhi and Chu Yan'er is very delicate, and it is not appropriate to appear here, so let Li Zhi stay outside the hospital, and the others will go back to their respective posts.

Ye Chu's face Chu Yan'er had seen it, in order to avoid suspicion, it was very inappropriate for Ye Chu and Li Zhi to appear here at the same time, so Ye Chu and Li Zhi, Fang Guangyun, Luo Shiwen, the four, also acted as passers-by, and quickly left the hospital, Ye Chu asked again, the situation of Cui Shangqing in the research institute was still safe according to Yang Bingchen's report.

When leaving, he met Han Fei, and after Han Fei saw Ye Chu, he also pretended not to know and left, and at the same time, the National Security Bureau quickly set up an investigation team to solve the case.

Half an hour later, Song Yunhu sent the news again that Cui Shangqing was gone.

After Ye Chu learned the news, he directly scolded his mother in his heart, but this also showed that the "Saints Organization" had also begun to take action against the Ark Project.

But now, there are already few people, and Wang Haiting and Chu Yan'er have gathered in the hospital, there are many doctors, nurses, and patients in the hospital, and everyone else can't drag their bodies, the only one who can drag them is Ye Chu.

After Ye Chu got the news, he also quickly rushed to the research institute, after Ye Chu passed through a dense jungle, he saw the gate of the research institute, the electronic door of the research institute was closed, and when Ye Chu's car arrived, Song Yunhu came out of the security room at the gate and opened the electronic door.

There was still some distance from the gate of the research institute to the dormitory building, Song Yunhu opened Ye Chu's car door without saying a word, sat down, and under Song Yunhu's guidance, Ye Chu also quickly arrived at the dormitory building of the research institute, and in the car, Song Yunhu told Ye Chu about the situation.

Since the radios of the eight people are all connected together, they can know what is happening to each other.

After Yang Bingchen and Song Yunhu learned that something happened to Wang Haiting, they converged, and in order not to arouse suspicion, the two were downstairs in the dormitory, guarding Cui Shangqing.

I heard from other security guards that Cui Shangqing has the habit of going to bed early, and under normal circumstances, he goes to bed at nine o'clock on time, but tonight the two of them stayed until nearly ten o'clock, but Cui Shangqing's dormitory was still lit.

Song Yunhu and Yang Bingchen wanted to go to Cui Shangqing's dormitory to find out, and when the two of them came to the door of Cui Shangqing's dormitory, they tried to knock on the door, but no one answered inside, thinking that Cui Shangqing was asleep, so they increased the force of knocking on the door, but still no one answered.

Song Yunhu and Yang Bingchen realized that the situation was wrong and found the security captain, hoping to get the key to Cui Shangqing's dormitory door, but the security office did not.

Because each researcher's dormitory security door key, only they have their own, Song Yunhu and Yang Bingchen can't use it, climb up from the pipe on the wall of the dormitory building, break the window of Cui Shangqing's dormitory, and when the two enter the room, they find that Cui Shangqing is not in the dormitory, only the light is on.

After the security guard of the research institute knew, he thought that Cui Shangqing had overcome the problem of research and went back to the laboratory to do experiments, but Yang Bingchen had been guarding downstairs and had never seen Cui Shangqing come out.

While talking, Ye Chu and Yang Bingchen entered Cui Shangqing's dormitory.

Ye Chu first took a turn around the dormitory, the dormitory layout is one bedroom and one living room, one kitchen and one bathroom, sofa TV and other furniture are readily available, and on the wall of the dormitory, there are photos of Cui Shangqing and his family.

On the floor near the desk, there was a stall of broken glass scattered on the ground, which Song Yunhu said he broke when he came in.

On the desk, there was a purple sand cup, and there was unfinished tea in it, Ye Chu put on disposable rubber gloves, touched the purple sand cup, felt the temperature, and was a little hot.

Ye Chu opened the lid of the cup again, looked at the tea inside, it was a Pu'er tea cake, Ye Chu put the lid back on the cup and said, "Cui Shangqing left not long ago, about half an hour. ”

Because the purple sand cup or purple sand pot has the function of heat preservation, it is not as fast as the heat dissipation of plastic cups or glasses, and the general drinking method of Pu'er tea cake is brewed with boiling water, and the heat dissipation speed is slower, not to mention that the lids of this purple sand cup are still buckled together.

Ye Chu saw the ashtray on the side of the desk again, there were no cigarette butts in it, obviously it had been cleaned up, it seemed that Cui Shangqing had a habit of smoking, although there were no cigarette butts in the ashtray, but the glass inside the ashtray was full of soot, there were two reasons for this situation, one was that Cui Shangqing had a great addiction to smoking, and after the ashtray was full, it was too late to clean, and the other was that Cui Shangqing had a very small addiction to cigarettes, but he never cleaned the ashtray.

Ye Chu asked: "Does Cui Shangqing have a habit of smoking?" Song Yunhu and Yang Bingchen obviously didn't know when they first came, but the people who worked with Cui Shangqing knew, not to mention that this movement was a bit big, outside Cui Shangqing's dormitory door, there were many people gathered, and after the people gathered outside the door heard Ye Chu's words, a researcher said: "Chief Engineer Cui has a great addiction to smoking, except for not being able to smoke in the laboratory, the rest of the time, he is basically a smoker." ”

Ye Chu nodded, looked at the other tables with his hand, and said, "Chief Engineer Cui's dormitory has been cleaned, how was the researcher's dormitory cleaned?"

Because since Cui Shangqing smokes, soot is indispensable, when Ye Chu checked the room before, he found that the trash can had been cleaned and was very clean, and there was no soot and dust on the table.

The captain of the security team is a veteran in his early thirties, his face reveals the unique perseverance of a soldier, and his standing posture is also straight, he said: "The researchers' dormitories are cleaned by special personnel, in order to ensure the safety of documents and personal safety in the researchers' dormitories, not to mention that everyone has a dormitory key, in the hands of the researchers, the cleaner in charge of cleaning can only clean when the researcher is present, and also have to register the cleaning time and the name of the person in charge of cleaning in the security department." ”

Saying that, a security guard came in from outside the door, holding a register in his hand and handing it to the security captain, who changed hands and handed the register to Ye Chu and said, "I thought the register would be used, so I asked someone to get it in advance." ”

Ye Chu glanced at the security captain and said, "Have you ever joined the army?"

The security captain regarded Ye Chu as a policeman, and Yang Bingchen and Fang Guangyun were also sent as police officers to secretly protect the security of the research institute. ”

After hearing this, Ye Chu said with a look of praise in his eyes: "I envy the soldiers, especially the special forces. Yin Kun nodded and said in a low voice, "Thank you." ”

At this time, Yang Yu's voice came from the earphones: "Yin Kun's identity is no problem, he retired two years ago, was recruited into the research institute, and became a security guard." ”

Ye Chu lowered his head and smiled after hearing this, he naturally knew that Yin Kun would not lie, because he was a Huaxia soldier.

Ye Chu opened the register, a person named Li Fazhu registered to clean Cui Shangqing's room an hour ago, and Yang Bingchen also said that there was a cleaner who went upstairs, but he came out soon and carried a big garbage bag.

Ye Chu asked Yin Kun, who was familiar with this place, to find a cleaner named Li Fazhu, and Yin Kun quickly sent his security guards to look for him.

When Ye Chu looked through the register, he smelled a faint smell of smoke, not smoking cigarettes, but the smell of paper being ignited, but the smell was very small, and he didn't notice it, Ye Chu said: "Someone in the research institute lit a fire?"

Yin Kun immediately said that in the institute, ignition is prohibited, and of course there is no problem with smoking.

Since Ye Chu cultivated his internal strength, his five senses are very sensitive, and Ye Chu rarely smokes, and his sense of smell is also good, Ye Chu pursued the smell of smoke, came to the door of the bathroom, took a deep breath, and determined that the smell of smoke came out of the bathroom.

Ye Chu glanced inside the bathroom, the bathroom was also cleaned, but in the corner of the toilet and the wall, Ye Chu saw a black block, which was left by the paper burning and the carbonization of water.

Ye Chu wiped it with his gloved hand on the corner of the toilet again, there were gray marks, Ye Chu sniffed again, and it was still the smell of smoke.

Ye Chu looked up at the top of the bathroom, and the exhaust pipe above his head was pumping the air in the room.

This shows that in the bathroom, someone has lit a fire and burned the paper, so it will leave the smell and paper ashes, what did Ye Chu think, in order to confirm his guess, he took off his coat, rolled up his sleeves, put his hand into the toilet, and touched the drain pipe of the toilet.

After this scene was seen by others, none of them did not have a disgusting expression on their faces, Yang Bingchen and Song Yunhu were naturally no exception, but Yin Kun was still resolute on his face, and his face did not change at all.

Ye Chu touched it in the toilet, as if he had touched something, his brows furrowed, and Song Yunhu and Kang Ran, who were watching from the sidelines, naturally thought that they had caught Xiang, and retched directly.
