We were worried that Professor Ba Leshan's office had been met by a burglar who had stolen an important document.

I thought for a moment and said, "I think that thief is probably here for the new drug information, who do you think is the most suspicious?" ”

Professor Ba Leshan was stunned, but he wanted to speak. At this time, Yu Manwen, who was sorting out the documents on the side, got up and lifted the kettle on the stove, made a cup of coffee for me and Professor Ba Leshan, and left.

It wasn't until she walked out of the office that Professor Ba Leshan whispered to me, "I'm a little suspicious of her. ”

"Miss Yu?" This surprised me.

Professor Ba Leshan nodded, "I already noticed that something was wrong with her last time, but I haven't said it. ”

I really didn't expect that Yu Manwen, who seems to be Sven, would do such a thing.

But now it's just a suspicion, and there is no conclusive evidence. If even Yu Manwen is Jiang Yucheng's person, then Jiang Yucheng is really a very powerful character.

"Okay, I'll go talk to her, maybe I can ask for some clues." I got up and walked out of Ba Leshan's office and went outside.

Yu Manwen smiled at me: "Mr. Wu, have you finished talking to Professor Ba?" ”

"Oh, it's not a big deal. Miss Yu, Professor Ba's office is a thief, have you noticed any suspicious people around? I asked her.

Yu Manwen shook his head and said, "I really didn't notice it, I don't know how the thief got in." ”

I asked tentatively, "Were you here all the time?" ”

"I was there most of the time, but I had an upset stomach and went to the toilet once in between. I think the thief took advantage of this time to come to Professor Ba Leshan's office to commit theft. Yu Manwen smiled and said.

Then I asked a few more questions, but I didn't find anything unusual about Yu Manwen.

As we finished chatting, we suddenly heard a scream from Professor Ba Leshan's office.

Yu Manwen and I hurried over and found Professor Ba Leshan slumped next to his chair and had stopped breathing.

"Call the police, call the police!" I turned to Manwen.

Yu Manwen panicked, and hurriedly grabbed the phone: "Hey, someone is dead here, come and ......"

After a while, several police officers arrived at the scene, including Zheng Ming.

Zheng Ming knew that I was coming to Professor Ba Leshan, but he didn't expect that there would be a fatality: "How did this happen?" ”

"I don't know, it was fine just now, but it was only a few minutes of work, why did he die?" I was also puzzled.

After a forensic autopsy, I learned that Professor Ba Leshan had died of a poisoned needle in the back of his neck.

But who will be the murderer? In such a short period of time, no one came in and out of the office, and how did the murderer do it?

I couldn't figure it out, Zheng Ming asked me to explain the whole process, and after listening to it, he didn't find any flaws.

I set my eyes on the kettle, thinking about the scene when Yu Manwen had just come in to make us coffee, and a bold idea came to my mind, it was a terrible scene, and I didn't want it to be true.

However, Professor Ba Leshan's previous words rang in my ears, and he suspected that Yu Manwen had stolen the documents about the new drug, so I had to accept this reality.

"Miss Yu, if I'm not mistaken, you killed Professor Ba, right?" I looked at Yu Manwen.

Everyone's eyes also fell on Yu Manwen, Yu Manwen was a little surprised, and hurriedly waved his hand and said, "This has nothing to do with me, Mr. Wu, how can you say such a thing?" When Professor Ba died, the two of us were chatting. ”

"I thought the same way before, you have a full alibi, and you don't have time to commit the crime at all, it would be too far-fetched to say that you are the murderer." When I said this, the conversation changed: "However, you took advantage of the time to make coffee for me and Professor Ba, plugged the spout of the kettle with a cork, inserted a poison needle into the cork, and continued to burn the kettle on the stove. As a result, when the water boiled, the steam pushed the cork out, and the poisonous needle on it stabbed Professor Ba in the back of the neck. This matter has been planned by you for a long time, you know how Professor Ba sits on weekdays, you just need to adjust the angle of the kettle, and it is not difficult to kill him in this way. At this time, the two of us are talking, you don't need to be there, you can kill people as well. ”

Hearing me say this, Yu Manwen's face became calm. She smiled bitterly and said, "I didn't expect to be seen through by you, that's right, I killed Professor Ba." ”

This time it was the turn of the others to be surprised, Zheng Ming asked, "Why are you doing this, Professor Ba has a grudge against you?" ”

"No, Professor Ba is very good to me, it's me who is sorry for him. Don't ask me about my motive for killing, anyway, I admit that I did it myself, and you can just arrest me. Yu Manwen didn't say anything else, so he directly confessed his guilt.

"What do you mean by this, since you admit that you are the murderer, but you don't explain the reason for the killing." I was a little puzzled and had to ask, "Is there something you have to hide?" ”

Yu Manwen said a little panicked: "No, I just want to steal the secret recipe of the new drug and sell it for money, it's that simple." ”

I further asked, "This matter is related to Jiang Yucheng, and he forced you to do this, right?" ”

Yu Manwen was even more panicked: "It has nothing to do with others, don't guess." ”

Zheng Ming glanced at me, and then said to Manwen: "She has confessed to her crimes, as for the motive for the killing, wait for me to take her back and interrogate her slowly." ”

I know there are too many people here, and if Yu Manwen says it, it will probably lead to death.

"Okay, I'll leave it to you cops." I say.

However, the secret recipe of the new drug was stolen, and who Yu Manwen handed it over to was the most important thing. Only by retrieving the secret recipe of the new medicine and not letting it fall into Jiang Yucheng's hands can we prevent terrible things from happening.

That night, Zheng Ming and Zhou Hao interrogated Yu Manwen, only to learn that the secret recipe had been taken by a person named Li Xinhong.

Li Xinhong, like Hu Muling, is also one of the important members of Jiang Yucheng's development of the "Heavenly Immortal Ghost".

is different from Hu Muling, Li Xinhong is definitely Jiang Yucheng's confidant. After he got the secret recipe for the new medicine, he would definitely hand it over to Jiang Yucheng as soon as possible.

"This kind of thing is not easy to do, even if we find Li Xinhong, we can't deal with Jiang Yucheng. According to Yu Manwen, it was Li Xinhong who always contacted her, and Jiang Yucheng never showed up. Zheng Ming frowned.

"No matter what, our top priority is to find Li Xinhong. Only by finding him can you stop everything. I said.
