Master Yan carefully searched for mechanisms on and around the circular relief, but unfortunately, there was not a single flaw in the entire wall, neither the relief nor the circular frame around the relief, nor a single gap.

"Da Yu, Yan Jianhua, you two put him over." Ouyang Ping looked at the True Dao.

Without waiting for Liu Dayu and Yan Jianhua to come to the front, Staff Officer Li and another armed policeman walked to the staircase with Zhizhen.

"True, where is the mechanism?"

"Captain Ouyang, this is a wall, where did the mechanism come from?" Zhizhen still has a fluke mentality.

"Master Yan, please pry this relief open."

Master Yan took a chisel and a hammer from his apprentice's hand.

A few minutes later, a gap about two centimeters wide and ten centimeters long was pried open in the relief.

Master Yan sticks the chisel into the gap. The chisel didn't reach its head—the length of the chisel was about thirty centimeters.

Apparently, there is a hidden place behind the relief.

Staff Officer Li lifted Zhizhen up, Zhizhen probably couldn't stand still, and his whole body fell down.

"True, where is the mechanism? If you don't say anything more, we'll force it open. ”

"Captain Ouyang, there's nothing you're looking for in it."

"Where's the agency?"

"On the fifth railing."

"Staff Officer Li, carry him up to the stairs and let him open the mechanism by himself."

The two of them drove up the stairs.

Zhizhen placed his right hand on the ball at the top of the fifth railing and turned the ball counterclockwise.

The ball made a sound of "Gada, Gada", and then a circular relief opened to both sides in the shape of a door—it was the circular relief that Master Yan had just knocked. This circular relief is just below the fifth balustrade.

Who would have thought that the mechanism would be placed at the top of the railing? The railing is hollow and the drive shaft is hidden inside the railing, which is a clever design.

As the circular relief slowly opened, a circular cave with a diameter of about 60 centimeters appeared in front of everyone.

Inside this circular cavern, there are two silver boxes that are equally large. The silver box is about 20 centimeters long, about 15 centimeters wide, and about 10 centimeters high, and the silver box is carved with exquisite patterns.

Ouyang Ping opened the silver box, one silver box contained three glass bottles, and one silver box contained two glass bottles.

Inside the glass bottles are some square cardboard boxes.

Ouyang Ping opened the cap - the cap is also glass, and the cap and the bottle body are tightly sealed, and the sealing is very good.

Everyone smelled a very strange smell, and Ouyang Ping suddenly had a very excited mood, accompanied by a feeling of dryness and heat. The smell didn't exist until the cap was opened, and neither did the feeling.

"Really, what's in these bottles?"

"It's medicine."

"Is it medicine? I'm afraid it's not an ordinary medicine, right? ”

"Captain Ouyang is right, the bottle is indeed not an ordinary medicine."

"What kind of medicine are they?"

"It's the medicine that Poor Dao usually uses before and after practicing."

"If it's medicine, why hide it in such a secret place?"

Elder Zhizhen, like Abbot Huijue, had a habit of hiding things, and according to common sense, people would hide only very important, or very valuable, things. Medicine, shouldn't be considered important - or valuable!
