"Niu Geng, the head chef asked me to come and see you, if you're fine, go to work tomorrow." Chu Feng saw Niu Geng coming, so he said a word to him.

When Niu Geng saw Chu Feng, he didn't show a scared look, but he was a little puzzled, this young man hadn't seen it himself, could it be that he was new?

"I see, I spoke to the head chef today. Niu Geng's tone was also very flat, without a trace of panic.

Chu Feng and Niu Geng said a few more words, and then left with Zi Yan.

"This guy is not lying, it seems that he is not the one who poisoned him. Ziyan said this, and his tone was very certain, if a person petitions, his eyes will always drift outward from time to time, and sometimes he doesn't dare to look at other people's eyes head-on.

"Could it be that the sous chef, he didn't come to work today, he left yesterday, according to common sense, he didn't have time to commit the crime. ”

Chu Feng calculated the time, this sous chef had already gone back yesterday, and there was no poison in the meal he ate yesterday, only in today's meal.

"Actually, I'm suspicious of another group of people, I just looked at the test report, XZ is a poison, as long as the person who takes it has heart disease, it has an 80% chance of inducing heart disease. ”

Chu Feng always had a question in his mind, whether this poison was given by Jack's people, Teacher Chen had a heart attack, but why did Jack take such a big risk? Rush to poison the meals of thousands of people.

"You suspect that it is Captain Jack, or the poison of his subordinates, then this is too crazy, isn't he afraid of the wrath of your superiors, and directly sent troops to destroy him. ”

Ziyan also guessed what Chu Feng was talking about, but he felt that Jack should not be so crazy, and if something really happened, the Huaxia government would definitely not let him go.

"Go back and check the surveillance, there should be surveillance in their cafeteria. Chu Feng thought for a while, at the time of the crime, he and Ziyan had forgotten that there was such a thing as surveillance.

The two returned to the hospital and came to the central control room, and asked the security guard to call up the monitoring of the hospital canteen.

Chu Feng looked at all the monitoring from the time the chef went to work to the time when they found out that it was poisonous, and found that there were no suspicious people who had been to the cafeteria, and no one was lying on the window of the meal and putting poison into it.

Soon, the police in Dingzhou came with the news that there was indeed something in the house of the sous chef named Li Xiaoming, and his father was injured in a fight with his fellow villagers, and he went back to take care of his father.

Now Chu Feng can basically rule out the suspicion of Niu Geng and Li Xiaoming, neither of whom came to work today, and they don't have time to poison them.

"Is there any monitoring of where you store rice, and if so, call it up for me to see, especially last night, after they got off work. ”

Chu Feng thought for a moment and decided to start from the warehouse where the rice was enlarged, in case someone had placed poison in the stored rice.

XZ This poison will not dissipate invisibly because it is wet, but it will spread throughout the water, which is forbidden in the country and is rarely used.

After a while, the security guard called out the monitoring of the warehouse where the rice was stored, and Chu Feng looked at all the monitoring of the whole night last night, but no one entered the warehouse except Niu Geng.

Niu Geng entered the warehouse, simply counted the amount of rice, and then left him without taking anything on his body.

"By the way, you don't mean that XZ won't disappear in the water, but will merge with the water and turn ordinary water into a poison potion. ”

Ziyan thought about it there for a while, but suddenly thought about putting that kind of poison, if there was that kind of poison in the water, then when washing the rice, the rice must have been sticky too.

Chu Feng listened to Ziyan's words, so they came to the cafeteria again, found Xu Fatzi, and now they are looking for today's rice washer.

"Fat Xu, how many times do you dig for rice, what kind of water do you use? Chu Feng found Fat Xu and saw that this guy was conducting some investigations with the people from the Health Bureau.

"They all use large basins of water, and these waters are all filtered water, and the rice has to be washed three times. Seeing that Chu Feng was in such a hurry, Fat Xu hurriedly answered his question.

"You go and call me the rice digger today, don't tell her that something is wrong, just say let him come and help." Chu Feng felt that the rice digger was the most suspicious now, he could put that poison in the water before washing the rice, and then let the rice be poisoned unconsciously.

After a while, Xu Fatzi brought a middle-aged man who looked to be in his 30s over, and Chu Feng's first feeling when he looked at him was that this person was very cold, and when his eyes were staring at you, it seemed like he was being targeted by a poisonous snake.

"Lao Qin, these two people have something to do with you, you have to cooperate with them well. Xu Fatzi introduced Chu Feng to this rice washer, and then left, he had to cooperate with the people from the Health Bureau to check some things.

"Lao Qin, you usually have to pick up a few basins of water when you wash rice!" Chu Feng took Lao Qin outside, and then handed him a cigarette.

"Under normal circumstances, there are five basins of water, all of which are the kind of filtered water that is connected, and now in the words of tap water, the iron content exceeds the standard, so we are not allowed to use it. ”

Lao Qin's voice was hoarse, like a crow, which made people sound a little uncomfortable.

"Then when you are washing rice, do you add something to it, such as XZ? After Chu Feng finished speaking, he kept staring at Lao Qin's eyes, if the person in front of him dared to lie, Chu Feng would definitely be able to see it.

"What is XZ, when we are washing rice, we don't put anything but gloves on. When Lao Qin heard Chu Feng's question, he was stunned for a moment, and then he said the answer.

"It's nothing, this is a task given to me by the bureau, and I just ask casually. ”

Chu Feng snorted and confused this question, although the people in the hospital cafeteria knew that today's meal was poisonous, they didn't know what type of poison it was.

"Can you give me the gloves you wore today, I'll take them back for testing, and I'll return them to you in two days." ”

Chu Feng just heard Lao Qin say that they would wear gloves when they washed rice, if there was xz on the gloves, it meant that Lao Qin was the one who poisoned him, or that after Lao Qin received the water, someone put xz in the water.

"Yes, I'll get it now. When Lao Qin heard that Chu Feng wanted his gloves, he immediately got up to get them, and Chu Feng followed behind him to prevent him from getting a new pair for himself.

After Chu Feng took the gloves, he handed them over to the people from the Health Bureau and asked them to quickly take them back for testing, focusing on testing what ingredients were on these gloves.
