At this time, Master Yan had also walked in front of this landscape painting.

"Master Yan, look at the back of this landscape painting." Ouyang Ping said.

Master Yan lifted up the landscape painting and carefully knocked it on the wooden wall with a candlestick for a few minutes.

"Master Yan, how is it?"

Master Yan shook his head.

Ouyang Ping glanced at Liu Dayu.

Liu Dayu walked to the door curtain and brought Wuji outside the door curtain.

There was a person standing outside the curtain, and he was Master Daoren. Daoren was afraid of disturbing the comrades' handling of the case, so he stood outside the curtain and waited for news.

Liu Dayu nodded at Daoren.

Daoren dragged Wuji to the bottom of the steps: "Wuji, you go in and out of the Heart Nourishing Palace three times a day, haven't you noticed a little strange?" ”

This is exactly what Liu Dayu wants to ask.

"The words you just brought are written in the truest sense." Wuji's words are amazing. Such an important person was ignored by everyone.

"Are you sure?"

"I saw what he wrote."

Liu Dayu lifted the curtain and beckoned to Ouyang Ping.

Ouyang Ping hurriedly walked out of the curtain.

"What's the situation?"

"Master Wuji, repeat what you just said."

"The words you just brought were written by the Elder of the Most True."

"Are you so sure?"

"I saw what he wrote with my own eyes, and at that time, I was still wondering why Elder Zhizhen didn't make a payment on it?"

"Why didn't you just say that?"

"I—I'm afraid."

"Don't be afraid, didn't you see that we had already arrested him?"

"Wuji has followed Zhizhen for so many years, and he has never treated Wuji badly."

"A devil like him, you don't have to have a conscience to get by." Dao Ren said, "Didn't you want to leave Ziyun Temple and live a normal life a long time ago? Have you already discovered that there is something shady in the end? ”

"You've looked at the stairs more than once, what are you looking at? Is the entrance to the secret room there? Ouyang Ping asked.

Wuji shook his head in horror.

"Master Wuji, you don't have to be afraid, can you tell me why you kept looking at the staircase just now?"

"I—"

"Don't worry, speak slowly." Liu Dayu encouraged.

"I often see Zhizhen standing at the bottom of the stairs, and whenever he sees me open the curtain, he flashes out of the staircase. He often asked me to dust off the walls and calligraphy and paintings with chicken feathers, but he never let me go to the staircase. ”

Ouyang Ping and Liu Dayu opened the door curtain, walked into the room, and stood at the door and could see the staircase, because of the light, the staircase looked very dark.

"Master Yan, take a look at the bottom of the stairs again." Ouyang Ping walked up to Master Yan.

The two masters carefully inspected the three or four square meters below the stairs. The scope of the first inspection is limited to the back of the painting.

When Master Yan knocked on the upper left corner of the landscape painting, about thirty or forty centimeters away from the stairs and about one hundred and fifty centimeters from the floor, the sound was abnormal.

"Captain Ouyang, the back of this plank is empty." Master Yan said.

Zhizhen also heard Master Yan's voice, and he turned his head to the staircase for the first time.

The place where the sound is empty is behind a round plank, the author has already explained in the front, the plank wall is composed of a combination of round planks, and each plank has a Taiji diagram, and the Taiji diagram appears in the form of relief.

Ouyang Ping could see panic and fear in Zhizhen's movements and eyes when he turned around.
