The three siblings' fears were justified. They really didn't cross the hurdle of Ran Shikai.

"Didn't you plan to use Ran Ruzhai to make a fuss about her shoes at the beginning?"

"When we're sure the old man has choked his last breath, we're—"

"You mean to say that the three sets of shoe prints were deliberately left in the secret room."

"Yes, originally, we didn't want to kill the old man, the old man is safe and sound, we don't have to worry about anything, the old man has an accident, we have to be cautious."

"That means you've been in and out of the backyard more than twice."

"Not bad."

"We found this button in the chamber." Chen Jie took the button from Liu Dayu's hand and walked up to Ran Shimei, "Whose button is this?" ”

Ran Shimei took the button, looked at the front and back carefully, and then shook her head: "This button is not on the clothes of the three of us." I have the impression that there was a person who had this kind of button nailed to his clothes. I remembered that Chen Guoquan once wore a Mao suit, and the buttons on the Mao suit were this kind of buttons. ”

"We have already investigated, and we have also seen Chen Guoquan's tunic with our own eyes, and his clothes are indeed such buttons, but the buttons are intact."

"Now, I've figured it out a little bit - before, Shixiong and Shijie hadn't figured it out."

"What do you understand?"

"The old man banged his head against the wall, he must be acting for us."

"Acting for you?"

"Yes, he banged his head against the wall to convince us that everything was in the chamber - and we did, and when he knew that we might take action against him, he moved a few other things to other places, and left three things in the chamber to fulfill our wishes, and the rest of them were safe."

"You mean to say that before you act, Ran Ruzhai was mentally prepared?"

"That's how it should be. When we got the things and walked out of the secret room, although he was in tears, but he was much calmer, in the face of three unfilial children, he was sad, but helpless, after we untied the rope on his body, he did not say anything except tears. We cleaned the wounds on his head and feet, and he seemed obedient, as if nothing had happened, and when we had settled the old man, we went out of the room and the front yard, and he got out of bed, and went out of the wing, and closed the door of the courtyard and the wing. When we left, he was fine, but when Shijie arrived in the front yard at four o'clock, the old man was—"

"What's the matter?"

And he died. We just tied him hand and foot, we didn't touch him, he just hit the back of his head against the wall a few times, how suddenly - we were all blinded all at once. We only wanted to take the contents of the secret room, and we didn't want to kill the old man. ”

If what Ran Shimei said is true, then the case is a bit complicated.

"Before inviting Liu Pong, did you clean Ran Ruzhai's wounds?"

"If you don't clean it, you can't do it!"

"Why is that?"

"The old man had a hole the size of a pigeon's egg in the back of his head, and blood kept gushing out. We stuffed cotton in the hole to stop the bleeding. ”

No wonder Liu Pang smelled a strong smell of blood.

"When you first left the front yard, did you notice a hole in the back of Ran Ruzhai's head?"
