Xin Zikai smiled and nodded.

However, Xiang Zhilan did not expect that Shen Muzhi would say at this moment, "You take him there, I still have something to say to Tingchuan."

This surprised Xiang Zhilan greatly. This stingy man was actually so generous this time, agreeing to let her deliver it alone.

But thinking about it, Ah Chao was the one driving, and he would definitely have reported it. He was probably just pretending to be generous.

"Okay." Xiang Zhilan turned to Xin Zikai and smiled, "Then let's go, Zikai."

The two walked out of the ward together, and Shen Muzhi's face immediately fell.

Xu Tingchuan felt a bit better after learning that Ni Sitian had a chance to be rescued. Seeing Shen Muzhi like this, he couldn't help but tease him, "You're clearly unhappy, why are you pretending to be generous? Aren't you afraid that Zhilan will run away with someone else?"

“I really have something to tell you.” Shen Muzhi sat down, took out a USB drive from his pocket, and said to Xu Tingchuan, “Someone sent this to me this morning. It contains all of Su Yan’s crimes, including Su Yan changing the dressing and killing Li Rui, as well as Su Yan embezzling Su’s public funds. The evidence is very detailed.”

“It must have been that person who did it.” Xu Tingchuan frowned slightly and said, “It seems that person not only knows Su Yan’s movements very well, but also knows us very well. He used to email me. This time, he probably knew that I was injured and hospitalized, so he handed over all the evidence he had collected to you.”

"Do you have any clues?" Shen Muzhi was very curious about who was behind this.

Xu Tingchuan shook his head. "He seems to be targeting Su Yan, but since it's inconvenient for him to show himself, he handed the things over to us to bring her down."

“Ever since I found out she was colluding with Li Rui, I’ve already investigated Su Yan thoroughly. She hasn’t offended anyone else.” Shen Muzhi couldn’t understand it. Su Yan was indeed utterly ruthless in her dealings with Xu Tingchuan, but as for other things, she didn’t seem to have done anything wrong.

“Let’s reason it the other way around. Li Rui has no relatives, and he doesn’t even have any friends in Yihai. This person definitely isn’t doing this for Li Rui.” Xu Tingchuan thought for a moment and then slowly said, “If it were for us, then it would be our friend. But our friends wouldn’t need to hide, so the final conclusion is…”

"For Su Chengwen, for the Su family," Shen Muzhi said, following Xu Tingchuan's reasoning.

Xu Tingchuan nodded and said, "Moreover, he secretly helped us, perhaps hoping that we would bring down Su Yan for him."

"But who cares so much about Su Chengwen and the Su family?" Shen Muzhi was even more puzzled.

Su Chengwen is already quite old. Since Su Yan died, he has lived a secluded life. His friends of the same age have all passed away, and he doesn't have many relatives.

"After thinking it over, I realized that the only person who could do this for Su Chengwen is Su Yan's mother. But Su Yan's mother wouldn't be so righteous as to send Su Yan to prison, would she?" Shen Muzhi shook his head with a smile. He felt that he was being delusional. Besides, Su's mother was as weak as a little white rabbit. She had been a Buddhist for many years and never left the house. She didn't even dare to speak loudly.

At the time, Su Chengwen chose such a weak and kind woman so that someone could take care of Su Yan and give the young Su Yan a mother.

Shen Muzhi still remembers that Su Yan and this stepmother had a very good relationship, like a biological mother and daughter. When Su Yan encountered a disaster, this stepmother even fainted from crying. After that, she became a vegetarian for many years to pray for Su Yan's well-being. This is not something that can be faked.
