With the second note in hand, Ouyang Ping already had a bottom in his heart, and Ouyang Ping even thought of the second move.

After breakfast, Ouyang Ping and his entourage went to the Tibetan Scripture Hall, and the craftsman had just finished breakfast.

Chen Jie and Yan Jianhua turned on the flashlight, Liu Wenbin turned on the emergency light, this emergency light was brought by Yan Jianhua and them, there is an emergency light, the problem of lighting is solved, and it is far from enough to rely on the flashlight to work in the dark passage.

Ouyang Ping, Liu Dayu, Master Chen, and Master Yan walked down the stone steps, and because the entrance space of the dark passage was narrow, the others stayed on it.

Master Yan took the flashlight from Chen Jie's hand and shone it on the stone slab from different angles.

Master Yan is looking for the texture on the slate, if you want to smash the slate open, you must figure out the texture of the slate, because the slate has been in a dark and humid environment for a long time, there is a layer of oxide layer on the surface of the slate, and the color of the surface of the slate has also changed greatly, and the oxide layer and color cover up the texture of the surface of the slate.

Master Yan rubbed his hand on the slate a few times, then took a hammer from Master Chen's hand that was square at one end and conical at the other, gently struck it on the lower right corner of the slate a few times, and then struck it diagonally downward.

Master Yan only knocked on the slate three times, and a corrugated crack appeared in the lower left corner of the slate—the corrugated crack was the texture of the slate.

Next, Master Yan slowly moved the striking point to the upper right corner, and without much effort, Master Yan appeared in several nearly parallel corrugated cracks on the slate - these corrugated cracks completely penetrated the entire stone slab.

When the hammer hit near the diagonal of the slate, Master Yan stopped tapping.

"Deshun, bring me the iron hook."

Deshun is Master Chen, and Master Chen has long held the iron hook in his hand.

Master Yan inserted the iron hook into a relatively wide crack, and then used force outward, and a long strip of stone slab slowly moved outward, and finally, Master Yan forced the hook outward, and the long stone edge was separated from the whole stone slab.

Master Yan took the long strip of stone in his hand and looked at it.

The thickness of the stone is about 12 centimeters and the width is about 7 centimeters. The front and back sides are flat, and the cross-section is irregular corrugated.

Ouyang Ping and Liu Dayu were more concerned about the back of the slate, and Ouyang Ping aimed the light pillar of the flashlight at a gap about seven centimeters wide.

Liu Dayu lay on the ground and looked at the gap about seven centimeters wide, and there was darkness behind the slate, which meant that there was no other shelter behind the slate.

After taking out a long stone, the other long stones will not be a problem.

Master Chen pried off all the stones that had been separated from the slate, and twenty minutes later, a black hole with a roughly triangular shape appeared in front of everyone's eyes.

Liu Dayu used a flashlight to shine into the black hole.

On the other side of the black hole is a relatively large space.

At the bottom of the slab, where the back of the slab is located, lay several large stones. These large stones are used to hold against the large stone slabs.

Master Yan motioned for everyone to take a few steps back, and after everyone retreated to the mouth of the pit, Master Yan picked up the hammer in his hand and knocked a few times on the other half of the stone slab, and the stone fell in response, and soon, a square stone slab came to naught.

Master Chen and several craftsmen moved the stones out of the entrance of the secret passage one by one.
