Jiang Cheng looked at Tang Qisheng's face, nodded after a moment of silence, "That's possible. It doesn't make sense for the ghost to kill someone first and then hang them. Also, the incense ash outside Mr. Zhang's room had been cleaned, those ghostly things don't seem like they would do that."

Tang Qisheng's expression turned cold. "I think that person didn't knock on the door at all. He climbed over the wall and ambushed Mr. Zhang by surprise. The reason why he only cleaned the incense ash there was because he accidentally stepped on it and left a mark."

Tang Qisheng's explanation made sense, but it was somewhat idealistic. It was difficult to corroborate based on the traces at the scene alone. Jiang Cheng knew he definitely had more to say.

Sure enough, Tang Qisheng turned and pointed to the corner, where some rarely used sundries were piled up, and the broom they used for cleaning was also piled there. "When we left, I was worried something might happen, so I hid my phone there and turned on the camera, but now... the phone is gone."

"The person who killed Mr. Zhang is very meticulous. He must have noticed my action of hiding the phone." Tang Qisheng gnashed his teeth in hatred.

His words were equivalent to stating it clearly: the person who killed Zhang Qizheng was among them. "Who do you suspect?" Jiang Cheng probed.

Tang Qisheng looked worried, his gaze swept towards the gate of the courtyard. "Who else could it be? It must be that bastard Shao Tong. There have been villagers watching me and Zhu Jie, as well as you and Brother Fugui, so we had no time to commit the crime, and no reason to. But Shao Tong and Yao Shunyu's group haven't returned yet, there must be a reason for this! I'm worried that Brother Yao has also fallen victim to his poisonous hands!"

Things were getting more and more complicated. Jiang Cheng decided to change the angle of approach. "There were footprints left in the courtyard, proving that those villager ghosts did come."

"You're right, so I think that person must have avoided the ghosts. The ghost villagers and that person came separately, one before the other." Tang Qisheng continued to analyze. "The only thing I'm not sure about is who came first?"

It was normal that Tang Qisheng couldn't figure out this question, but Jiang Cheng knew in his heart that the ghost villagers definitely came first, and that person came later, because if that person had returned first, then Wu You would have caught him red-handed.

So the order should be like this: not long after they left, the ghost villagers arrived first and carried away the faking-death Li Bai, and Wu You was also taken away along with him. At this time, Zhang Qisheng was not dead yet. Then that person sneaked back, ambushed and killed Zhang Qizheng, who thought he had escaped a disaster and relaxed his vigilance. After arranging the scene, this person finally took away the hidden phone.

Although Zhang Qizheng hadn't shown off his skills too much, judging from his aura and steps, he was clearly a trained martial artist. Even with a sneak attack, it wouldn't be so easy to kill him. The person who killed him was very likely to have scars on his body.

Just as he was thinking about this, a burst of rapid footsteps suddenly sounded outside the courtyard. Fatty Zhu Jie rushed over upon hearing the sound. The courtyard door was pushed open, and a group of people walked in, covered in dust. They were also carrying an old door panel. The fatty was immediately dumbfounded, because Yao Shunyu was lying on the door panel, covered in mud and fallen leaves. The exposed skin had many scratches, and he looked like he had fainted.

"What's going on?" The fatty immediately questioned Shao Tong, who was helping to carry the door panel. He was relatively clean, but his shoes were covered in mud.

The leading villager apologized repeatedly. "Oh, don't even mention it. I'm really sorry. The fog outside was heavy. The person leading us wanted to go further to find people, but we didn't expect to get lost. Before we knew it, we had turned out of the village. Then, as we were walking, this brother disappeared. We searched for a long time, and finally found that he had accidentally fallen off a hillside. He had also fainted. It took us a lot of effort to carry him back."

Tang Qisheng was a little surprised. He glanced at Shao Tong and continued to ask the leading villager, "Was this Brother Yao the only one who went missing?"

The leading villager was stunned for a moment, seemingly not understanding his meaning. "What, you think it's not enough that one person went missing?"

"No, I wanted to ask where this Brother Shao was at the time?" Tang Qisheng smiled and simply stated it clearly. "After all, Yao Shunyu is one of us, it wouldn't be right for Brother Shao not to help."

"Oh, you're talking about this Brother Shao. He was with us the whole time searching for people. In the end, he and I went down together to tie the rope, and then we pulled him up." The villager raised his dirty hand and said.

Shao Tong looked at Tang Qisheng with a strange expression. After a moment, he looked around, as if he suddenly realized something. "Where's Zhang Qizheng?"

Jiang Cheng and the others did not answer his question immediately, but instead sent the villagers away first. Before leaving, the villagers did not forget to comfort Jiang Cheng and the others, saying that they didn't need to worry too much. After finding the person, they had checked him as soon as possible. They were just some abrasions and impact injuries, and he would be fine after resting for a while. There was nothing serious.

After the villagers left, the fatty and the others carried the unconscious Yao Shunyu into Li Bai's room. Seeing that Li Bai was gone, Shao Tong looked at Jiang Cheng. Jiang Cheng took him to another room. When he saw Zhang Qizheng hanging from the beam, Shao Tong's pupils shrank and his face instantly darkened. "With Wu You here, who has the ability to kill someone?"

After a while, he shook his head again. "No, it's the order. The villagers carried away Li Bai and Wu You first, and then Zhang Qizheng was killed."

But after Jiang Cheng briefly introduced the situation here to him, Shao Tong fell silent. He looked at Jiang Cheng with a strange look in his eyes. "So... the murderer can only be one of me and Yao Shunyu, right?"

"If there are no accidents, that should be the case." Jiang Cheng was very frank.

"Fortunately, I thought you would say that if there are no accidents, I am the murderer." Shao Tong smiled self-deprecatingly.

"I'm not that stubborn. Although I suspected you before, I can tell whether what you're saying makes sense or not, and this matter concerns whether all of us can survive." Jiang Cheng lowered his voice. "I thought of something before, even if the murderer ambushes and wants to kill Zhang Qizheng, it won't be easy, so the murderer is likely to have traces of fighting left on his body, but now..." Jiang Cheng looked in another direction, "I think there's no way to verify it."

Shao Tong nodded thoughtfully. "Yao Shunyu fell off a hillside and is covered in injuries, which can just cover up the fact that he was injured, and he has been missing for so long, he has plenty of time to commit the crime."

"His disappearance at that time was very strange. He got lost in the fog while walking. At first, I thought it was the villagers who were playing tricks."

Jiang Cheng took a deep breath. "Don't disturb him yet. After we have a breakthrough with Wu You, we'll make plans."

"Understood."

Jiang Cheng lifted up a chair, gestured at the height with his hand, and turned to Shao Tong and said, "Go get a broom, let's put Zhang Qizheng's body down first, there may be clues on it."

Shao Tong turned and walked out the door, heading straight for the courtyard gate. Jiang Cheng stared at his back, the light in his eyes dimmed, and even became somewhat cold.
