The room was clean and neat and looked organized.

Obviously, Li Shanya is a very self-disciplined man.

Chu Mufeng could draw this conclusion just from the arrangement of the room. After searching, he found that as expected, there was no valuable clue here.

The doubts you want to find do not exist.

There were some French coins and a small yellow book in the drawer in the wardrobe, and there were several historical books on the bookshelf in the corner of the wall. On the coffee table next to the window, two pots of longevity flowers were blooming in full swing.

That's all.

"Everyone says that Yan Fengchun is doing things without any leakage. Now it seems that this is true. Any intelligence officer under his command is so self-disciplined. How can he, as the deputy webmaster, be an ordinary character?"

The mature and steadfast Wu Jinyao.

Yan Fengchun, who is not leaking.

Luo Liefeng is cruel to do things.

The Tianjin Station in the past was really lively. If it weren't for Luo Liefeng's defection, it would be difficult for Wu Jinyao, who was in the backstage, to take over the power alone.

Chu Mufeng thought to himself, turned around and left.

"How is it, Inspector Chu, have you noticed it?" Xu Xiaode couldn't help but ask in a low voice.

"Go to Cao Tianyi's house to have a look." Chu Mufeng refused to comment.

"good!"

Xu Xiaode knew the rules here, and without further questions, he turned around and took Chu Mufeng away.

Half an hour.

"You said this is Cao Tianyi's home?" Chu Mufeng pointed to the house in front of him and asked with a strange expression.

"Yes, the address is here, there should be no mistakes." Xu Xiaode said.

"That's interesting."

Although Chu Mufeng is not very familiar with the terrain of Tianjin, he is not familiar with it anymore. On the way he came just now, he happened to pass by the alley of Zhao Qingfeng's house.

Calculate the time, it takes only five minutes to get here from there. If you run, you will probably take ten minutes to get there through the streets and alleys.

Could it be Cao Tianyi?

"Knock on the door!"

With the sound of knocking on the door, a woman walked out from inside. She was about thirty years old, and looked a little old and dressed quite simple.

After seeing two strangers in front of her, she couldn't help but ask in confusion.

"Who are you looking for?"

"You are Cao Tianyi's wife Wang Guiying, right?" Chu Mufeng asked with a smile.

"Yes, I am." Wang Guiying nodded.

"Oh, we are from Lixing Shejin Station. I'll ask you a few words."

"Didn't you just ask?"

When Wang Guiying heard this, she frowned and muttered with some annoyance: "Just just left, but came back. What's wrong with this? Is there endless trouble?"

"Wang Guiying, what are you talking about? This is Inspector Chu who came from Jinling and is a nobleman from Tianjin Station! If you ask, just explain honestly and don't complain here!" Xu Xiaode shouted sternly.

"As long as you know, ask!"

After being scolded, Wang Guiying immediately did not dare to mumble again, lowered her eyebrows and said with a straight face: "If you want to know, ask me if you want to ask Lao Cao if he slept at home last night?"

"Yes, he was at home. We went to bed at around nine o'clock and didn't get up until after six o'clock the next morning."

"I'll go in and take a look, it's okay." Chu Mufeng pointed to the yard and said.

"Go in!"

After walking in, Chu Mufeng began to wander along the courtyard. After confirming that there was nothing strange here, he walked into the room.

The moment he walked in, his nose couldn't help but sniff, and a flash of light flashed quickly in his eyes.

"Wang Guiying, you couple have a good relationship, right?"

Chu Mufeng casually glanced around, and his steps gradually approached the bedroom door.

"Of course, our old Cao is a kind person and he has a good relationship with me." Wang Guiying opened her mouth and said.

"What do you usually cook after dinner tonight?"

"What else can I do? Of course I'm going to bed."

"Can I go inside and take a look?" Chu Mufeng said, pointing to the bedroom.

"Sir, I said no, don't you go in?"

Hearing Wang Guiying's slightly resentful words, Chu Mufeng was too lazy to say anything and walked in directly.

As soon as I came in, I saw a small incense burner on the head of the bed.

The fragrance inside had been burned long ago. Even though the windows were open, there was still a faint smell in the room.

This smell cannot be smelled at all for people with insensitive sense of smell.

It's indeed this!

"Do you guys order this incense tonight?" Chu Mufeng pointed to the incense burner and asked casually.

"This is not cheap. I order it once a while. Every time, it is when Lao Cao said he couldn't sleep. He said he couldn't sleep yesterday, so he ordered one."

Wang Guiying answered readily without hesitation.

"Take this away!" Chu Mufeng pointed to the incense burner and said.

"yes!"

Xu Xiaode quickly stepped forward and wrapped the incense burner.

"Oh, aren't you asking? How can you just take our stuff? This is..."

"Stop talking nonsense, let Lao Cao take it back for you later, just talk about it and go back to the station with us."

Xu Xiaode yelled at Wang Guiying in anger, and then picked up the incense burner.

"Then remember to let Lao Cao bring it back!" Wang Guiying had a bitter face, full of helplessness.

Chu Mufeng looked around again and then turned around and left.

He knew in his heart that although Cao Tianyi was not an intelligence officer, he was working in the Lixing Society after all.

If he is really a spy, how could he keep important information or clues at home?

Outside the door.

"Inspector Chu, are we going back now?" Xu Xiaode asked.

"Xu Xiaode, send someone to monitor the place and find that Wang Guiying has any signs of escaping, so take it down directly!" Chu Mufeng pointed at the back and ordered in a deep voice.

"Inspector Chu, you mean..." Xu Xiaode looked surprised.

"Do it!" Chu Mufeng did not explain too much and directly ordered.

"Yes, yes!" Xu Xiaode was excited.

...

Lixingshe, Tianjin Station Station Manager's Office.

When Chu Mufeng came in with his package, Wu Jinyao immediately stood up and greeted him, asking with concern: "Inspector Chu, how did you investigate with their two families? Have you found anything?"

"If nothing unexpected happens, maybe I already know who the murderer is." Chu Mufeng nodded and said.

"Did you find it?" Wu Jinyao looked surprised.

"Who is it?" Yin Pingzhi also asked.

"Cao Tianyi!"

"It's him? It's impossible, why did he do this?" Wu Jinyao frowned.

"Nothing is impossible, nothing is possible!"

Chu Mufeng sneered and took the incense burner out of the package and put it on the table, then said loudly: "We have also said before that Ma Huaihua from the Operations Department and Zhao Zhipeng from the Gendarmerie can rule out the suspicion, so the rest are Cao Tianyi from the Archives Department and Li Shanya from the Intelligence Department. They have a major possibility of committing crimes."

"So I went to their house to search. I found nothing wrong with Li Shanya's house, but at Cao Tianyi's house, I found this incense burner!"

Chu Mufeng raised his finger to the incense burner and said with a little chill: "I think even Cao Tianyi never thought that the incense burner would become physical evidence and expose him, otherwise he would definitely put it away."

"Of course, it may be that he was a little panicked because of an accident, so he ignored this, but no matter what, this incense burner is evidence."

"Inspector Chu, isn't this a very ordinary incense burner? There are many incense burners like this in Tianjin antique market, which is not surprising." Wu Jinyao was a little confused.

"Inspector Chu, please decrypt it to us quickly." Yin Pingzhi asked with interest.

"Yes, the incense burner is very ordinary, but the incense light inside is not ordinary."

Chu Mufeng pointed to a small Duan Xiang left in the ashes and said, "Website Manager Wu, Director Yin, you two may not have much research on this, but I happen to know this fragrance."
