After listening to Zhang Guozhong's words, everyone looked at the stone slab under Chijigeng. Although they didn't know how thick it was, the weight was definitely not light based on the area alone.

"Guozhong, why don't we set up a blue dragon and red blood formation?" Although Old Liu was talking to Zhang Guozhong, his eyes were always staring at the stone slab.

"Yes, Master Zhang, if we can escape that way, I think we can try it too..." Qin Ge also began to add fuel to the fire.

"This... OK!" Zhang Guozhong couldn't resist the persuasion, and did not think deeply at this time, "Yicheng, Mr. Sun, take out the things in the bag first, we have to use packaging red salt..."

In just two minutes, Sun Ting and Zhang Yicheng were already filled with two large bags of red salt. "Brother Ai, I will go down from that patio, swim back to the Tianmen, wait for my signal and start pouring red salt into the pool!" When encountering such a thing, Zhang Guozhong still believed in Alxun. After all, Sun Ting was a literati and might be fooled by emergency situations.

"What are you going to send a signal?" Alxun was stunned. The walkie-talkie could not use water in the walkie-talkie. The patio seemed to be quite long, so it would definitely not be able to be emitted with a flashlight, and it would be difficult to hear it if you shouted.

"This... give me a gun. After opening the door and let it go, I fired the gun. The passage can be more or less closed, and the gunshot should be heard..." Zhang Guozhong had never fired the gun. At this time, the heavy pistol was held in his hand, and he was really scared. "I started setting up the formation after three minutes after firing the gun. In these three minutes, you will have to fall down all the red salt..."

After bringing Sun Ting and Alxun to the entrance of the courtyard, Zhang Guozhong sacrificed Alxun's finger again, drew a "dragon-inducing talisman" with Alxun's "boy's eyebrows", put it in the mineral water bottle brought in by Zhang Yicheng, and jumped into the water with a plop.

Not to mention, the two blind iron-locked corpses were quite persistent and were still guarding the bottom at this moment. Zhang Guozhong jumped into the water. The two grandpas moved, but in an instant it seemed that they had lost their target again.

After a fierce thrust for twenty meters, Zhang Guozhong poked his head out of the water and changed his breath and started swimming again. After a few steps, he swam to the stairs when he was down. After climbing up the "Tianmen", he pulled down the wooden stakes that blocked the spring of the "Tianmen". He saw the clear spring water pouring out like a small waterfall. Zhang Guozhong squatted beside the entrance of the cave and carefully observed the water level in the passage. Because the water level in the passage was originally flush with the lower edge of the water channel on the stone walls on both sides, so there was no need to be too much. As long as the water level rose by one centimeter, it could flow into the water channel on both sides of the passage.

When the water was released for about half an hour, Zhang Guozhong suddenly heard a vague sound of water in the cave behind him, and it was not a place that sounded, and it sounded like a group of ducks going down the river.

"It's broken!" Zhang Guozhong's whole body trembled suddenly. Every cave hanging on the "iron-locked corpse" cage in this cave was opened with water channels. The spring was blocked and the water was not circulated. These things seemed to be nothing, but as soon as the spring was boiling and circulating, would those things come alive?

Thinking of this, Zhang Guozhong opened the entrance of the passage at the Insurance Chaotianmen and fired two or three shots in succession, and then began to pinch the meter.

At the other end of the passage, Alxun was lying on the ground and listening to the movements in the passage. At this moment, he heard the gunshot and immediately stood up and started pouring red salt into the courtyard with Sun Ting. Within two minutes, the water surface under the patio was red, and even the two black grandpas in the water were attracted...

Time passed by minute by minute, and the sound of the water behind Zhang Guozhong became more and more intense at this end of the waterway. To be honest, Zhang Guozhong was a little uneasy at this time, and he was alone. If the formation was not arranged properly, it attracted a group of those things, and he might not be able to find the corpse in the capital...

Seeing that the time was almost over, Zhang Guozhong waved his sword and threw the dragon-guiding talisman into the water. He saw that the originally calm water surface in the passage gradually began to roll, and then gradually turned to boiling. As the waves on the water surface roared, the water sound behind Zhang Guozhong gradually became smaller. In less than five minutes, the water sound actually disappeared...

After blocking the spring with wooden stakes, Zhang Guozhong went down the passage again. He saw the sparsely suspended particles of red-nitrogen in the water, which seemed to have not been completely calm. The two blind "black grandfathers" not far away seemed to have become statues at this moment, allowing Zhang Guozhong to be pulled onto the courtyard by Alxun under his nose, but there was no reaction.

"President Zhang... It's such a miracle..." Sun Ting really regretted not taking the camera to capture the incredible wonders in front of him. People can use some "red clay" to create such a wonder!

"Haha, nothing... nothing..." After being pulled into the courtyard, Zhang Guozhong wiped his face, "Where are senior brothers and the others... Let's go out quickly... It seems that these things have temporarily lost their combat power..."

"They... probably haven't come out in that dark room yet..." Sun Ting shook his bag and walked straight to the secret door. "Senior Liu just said he wanted to study what was carved on the wall of the room..."

"Senior Brother... Yicheng... The formation is finished... Come out quickly... It's too big, and the formation will not last long. Let's go quickly... Senior Brother!?" In the narrow passage, Zhang Guozhong began to yell at the dark room, but there was no answer in the secret room.

"Senior Brother!?" Zhang Guozhong followed Sun Ting into the dark room, and shot everywhere with a flashlight, but there was no one in sight.

"Senior Brother! Yicheng!" Zhang Guozhong's flashlight subconsciously shone to the place where he dug the red slab just now. It would be fine if he didn't. When he almost fainted, he saw that the "corpse of the word" on the ground was pressed down by a large stone slab one meter square, one foot and a half thick. There was no need to ask, there must be any passage under the stone slab. The people in the room must have lifted the stone slab while Zhang Guozhong was out to set up the formation. He could lift such a heavy stone slab. No need to ask, it must be the one who was the big hand Liu Gan again... "These people! I really think they are here to travel...!" Zhang Guozhong walked to the place where he dug the red slab just now, and the place where he was originally covered by the stone slabs turned into a dark entrance, just like a rural cellar. A row of steep steps led straight to the darkness underground. The cave was filled with fog, and the flashlight could only shine seven or eight meters away.

"Mr. Sun, Mr. Ai, stay here and don't move. I'll go down to find them!" Zhang Guozhong returned the pistol to Alxun, "It should be very safe here..."

"Oh... OK..." Alxun sat on the stone slab pressing on the "charm of the word".

"Yicheng! Senior brother!" Zhang Guozhong shouted while going down the steps. It would be strange if he said it. After about thirty or forty junctures, a flat passage appeared in front of him. He started to go up the steps without walking five or six meters. From time to time, there were some "curves". After turning up and down, left and right for four or five times, Zhang Guozhong finally heard the "response" inside, "Don't shout! Hurry up and discover the new continent!" Hearing the voice, the person who called out should be Lao Liu.

"Senior Brother! It's too big here! I'm afraid the aura will not last long!" Hearing that nothing happened inside, Zhang Guozhong also let go of his heart. He took two steps in three steps and started to jump forward. After about two more bends, he suddenly realized that the passage began to radiate into a huge artificial cave. The two huge stone doors were at least three meters high, and one of them was blown up by explosives. It seemed that Lao Liu and others entered from here.

"Guozhong... Come in! Look at these!" Seeing a flashlight coming from a distance, Old Liu suddenly poked his head out of the gap, which scared Zhang Guozhong, "Senior brother, stop playing, go quickly! I was setting up a formation outside just now and heard the rustling sound of water. What if those things will survive in a while?"

"Hey, come in first..." Old Liu poked out and pulled Zhang Guozhong into the stone gate. He saw that the space inside the stone gate seemed quite large, at least 200 square meters.

"This is where the person who built the pond died..." Old Liu stroked his goatee and said, "The wind in this room means that this big brother should have lived here in the last few days, or... it is very likely that he would live here when he was building a cave above..." In fact, without Lao Liu's words, Zhang Guozhong was cold all over and was very sensitive to air flow. As soon as he entered this stone chamber, he felt that the left half of his body was cold.

"Living here..." Zhang Guozhong illuminated the flashlight and saw a stone bed in the corner of the stone chamber. Liu Zheng, the big hand, sat silly on the bed, and there was a stone table in the middle of the stone chamber. The shape was similar to the stone tables outside. Next to the stone bed was an iron table of metal, about two meters long and about one meter wide. The table was filled with messy things. I don't know what it was, Qin Ge and Zhang Yicheng stood and were lying down and snatching lice.

"Look, there is a bed, which means he has slept here, there is a table, which means he has written words here, and there is a test bench..." Old Liu pointed to the stone bench in the middle of the stone chamber, "First do the experiment here, and if the experiment is successful, it will be promoted to the top..."

"It's not writing..." Qin Ge, who had been "catching lice" in front of the table, suddenly spoke at this time, "It's engraving!" While speaking, Qin Ge carefully picked up a strange tool that seemed to be a carving knife. "The Qin Dynasty had not invented papermaking technology yet, and most of the documents should be made of 'silver' or 'silver'. I have seen tools specifically for engraving 'bamboo slips', and it's definitely not like this..." After that, Qin Ge put this strange tool in his bag.

"Dad..." Zhang Yicheng suddenly screamed, and even Qin Ge next to him was shocked, "Look at this..." Zhang Yicheng was holding a stone box the size of a soap box in his hand, and the lid was gone.
