Captain Wu is also decisive in his work. Just after Musen had just released the profile, he was already in a hurry to ask him to go to the school to investigate the crime location that matched his characteristics.

But as a result, there was only one cold storage within a very close distance from the school, but the security system of this cold storage was very complete and there was no sign of outsiders invasion. The surveillance camera can monitor everything inside and outside the cold storage door, and there is indeed no abnormality.

However, in the school, there is a small cold storage behind the canteen. Usually, it is to store some meat and food. It is less than ten square meters, and it is made by the small boss who contracted the school canteen himself. Although the specifications are not as good as regular cold storage, the temperature inside is definitely below zero after starting the facility. In order to save electricity, the boss only starts the cold storage when needed.

Captain Wu told Mu Sen the news. Mu Sen did not hesitate to ask Captain Wu to immediately bring the people who contracted the canteen back to the police force. This is the key. The cold storage in the school is much more convenient than the ones outside!

On that day, the canteen contractor was taken to the police force. He was a middle-aged man who looked very smart. He started to watch around as soon as he entered the police force, obviously looking guilty.

When he sat in front of Musen, he still looked at Musen with an innocent expression, and the expression seemed to prove his innocence. Although, he didn't know why he was brought to the police force.

Musen stared at the man in front of him coldly. The longer he didn't speak, the more restless the man became. After a long time, Musen asked coldly: "Don't individual contracting is not allowed in the school cafeteria?"

When the man heard Musen finally spoke, he quickly replied with a smile: "No, no, no, comrade police officer, this law requires that the company that contracts the canteen must have more than three years of experience in operating large restaurants. I have, I have experience."

"Are you a company?" Musen looked coldly at this speculative businessman who is good at taking advantage of legal loopholes.

However, the man was very shameless. He touched his nose and said, "What do you think is a company? This company is divided into large, medium and small. I have enterprises and experience. To be honest, it has many benefits to the principal... It is legal. Why did you invite me here for... Are there any students who make unreasonable noises and say that the food in our canteen is not delicious? It is not clean? Ouch. You can't listen to those young ancestors who are nonsense. They are spoiled and picky about food..."

Before the man could finish speaking, Musen interrupted impatiently: "Name."

"Hu Laifa." The man answered respectfully. Musen knew in his heart that the campus case should have nothing to do with this person. What this person has been worried about since he joined the police force was whether he operated legally and food safety issues, not about murder.

Musen smiled a little sarcastically at this name Hu Laifa. The name is really wonderful, and it matches everything about the man in front of him.

"I'll ask you, who has the key to your cold storage?" Musen asked directly the question he really wanted to know.

But Hu Laifa said carelessly: "The principal has it, the teachers have it, and many people have it. They are all willing to save things in my place. In order to establish a good relationship with the school, I am also generous. Anyway, there is nothing but a little meat in it. I am not afraid of stealing, and the school can also pay some electricity bills for me. Why not?"

Musen frowned as soon as he heard this. If many people have this cold storage key, it would be even more troublesome. So Musen asked again: "Have you ever had any abnormalities in your cold storage? For example, what's inside has been moved or something?"

"Of course there is. If someone goes in, there will be changes inside. But I have never cared about it. It is a blessing to suffer losses, but being kind." Hu Laifa smiled, but Captain Wu, who was outside the door, almost broke into the door and beat him up. This 251st beat.

Musen also knew that Hu Laifa, who was profit-oriented, could not ask any clues, so he had to ask with the last hope: "Among the school staff with your cold storage key, do you think you are a little abnormal?"

"Improper? Sorry, the police officer...what is abnormal?" Hu Laifa said, then looked around and said in a low voice: "Don't look at them all as role models. But in fact, there are many hypocritical hypocrites! There are extramarital affairs, some raising young men, and some secretly having a teacher-student relationship. To be honest, it's not much nobler than me! Look at my canteen food, the food may be a bit worse, but the fresh meat and eggs are all distributed to the teacher. Let you tell me, there is no normal thing!"

Musen couldn't hear anything about what Hu Laifa said. He closed the record book and pushed it to Hu Laifa and said, "Write out all the names of everyone with your cold storage key, and one less, don't think about doing your cafeteria."

After saying that, Musen stood up and walked out of the inquiry room. He knew that Hu Laifa would cooperate well with his interests.

As soon as he went out, he saw Captain Wu with a gray face outside the door. Captain Wu couldn't help complaining when he saw Mu Sen: "This profit-oriented 25 should do him! With him like this, he would never use a penny if he could use five points in the ingredients. Can he still expect him to make a meal for the students with confidence?"

Musen looked at Captain Wu and said rationally and ruthlessly: "The food safety issues are not subject to the serious crime team of your Criminal Police Team, and I am not subject to me. Whoever should be responsible for these issues is investigated? I am only responsible for investigating the four murders."

"You..." Captain Wu was unhappy, but there was nothing to refute Musen's words. Because the food in the cafeteria was not clean and suited to the students' appetites, it was indeed not something they should worry about. So despite being angry, Captain Wu didn't say anything after all.

At this time, Mu Sen said to Captain Wu again: "Go in and check out his list, and make the identity of everyone detailed. I'm going to go to school now."

"Do you need to send someone to come with you?" Captain Wu asked.

"No need. You can do it first." After that, Musen strode away.

Looking at Mu Sen's back, Captain Wu complained in his heart: A weird person is a weird person. No matter how long he has been in contact, he will never see any normal change. He is mean, but what he does is just. But if he is kind, he seems to be cold-blooded than anyone else. This Mu Sen's weirdness is really incomprehensible.

After leaving the police force, Mu Sen dialed Jin Yu's phone number. The honest child told Mu Sen that he was sorting out the information. It turned out that he had printed out all the messages he collected, so that Mu Sen could see it for the convenience of Mu Sen.
