There was no lock on the wooden door, only a brass handle rusted green, Qin Wuwu half-bent down, grabbed the brass handle and pulled it up hard, the heavy wooden door suddenly opened with a piercing squeak, and then, a heavy fishy smell came to his face.

Qin Wufu sniffed, his brows immediately furrowed, this strong fishy smell came from the soil layer below, the wooden door was originally supposed to be a passage, but now it was completely covered by the soil layer, and there was a layer of cement on it, and it had hardened into a ball over time.

"There used to be a tunnel down here, but it was buried."

A-Ning walked around and watched.

"Could it be that something is wrong in the tunnel?" She crossed her shoulders and watched, meaningfully.

Qin Wufu didn't say anything, greeted Wang Hao, and the two of them dragged in a box of things from the outside, and there were iron drills, shovels, chisels, hammers, and various tools inside.

A-Ning laughed: "What are you doing with so many things, come prepared?" ”

Wang Hao said: "This is all left by the previous owner, I saw it just now, and now I just use it." ”

Qin Wufu didn't speak, beckoned Wang Hao to come to the vicinity of the wooden door, smashed the surface lump with a chisel and lifted it out, and smashed the cement surface with an iron drill and hammer little by little, and the gravel slag splashed in all directions for a while.

The two of them held the hammer very hard and smashed it on the ground, making them disgraced and unable to see their original faces.

"Mouse, you're in charge of digging the hole, A-Ning, you're helping to disperse the soil." Qin commanded uselessly.

A-Ning watched them silently, and the figure was a little blurry under the flickering lights in the room.

Wang Hao raised his head by chance and smiled at her.

I saw that Wang Hao and Qin Wuwu each had a shovel, the dirt was flying, the pit on the ground was dug extremely fast, and the straight circle hole had gone down more than a meter deep in a blink of an eye.

At this time, Wang Hao, whose whole body was already buried in the hole, shouted from below: "Old Qin, the shovel has touched a hard guy, it seems that it has dug bricks!" ”

Qin Wufu and A Ning were both shocked, approached the past, and let Wang Hao come out of the cave first.

Qin Wufu climbed into the hole in the ground to see, tied his body with a nylon rope, wrapped around his waist from under his armpits, and then put it in little by little.

The hole was about two and a half meters deep, and Qin Wuwu stepped on the bottom of the cave with his shoes, and the soil was a little wet, as if there was underground river water seeping out.

Qin Wufu stretched out his hand and touched the wall of the cave, and found that these wet water droplets were all dripping down from the wall, and it was certain that it was at a high level below the ground, and it should be adjacent to an underground dark river.

Touching the two blue and white streaks knocked out by the shovel at the bottom of the cave, Qin Wufu sniffed his fingertips, a sour and moldy smell.

"How's it going?" Wang Hao poked his head from the top of the cave and asked.

"It's a layer of rammed earth, and there may be a dungeon down there! Break open the glazed roof above the dungeon, open the glazed roof and open the tomb below, it seems that we have dug up something terrible! ”

"Then how do you open that roof?"

"Go to the old man's house and borrow some vinegar, mix it with hot water, and throw it to me."

Wang Hao came back after borrowing vinegar, Qin Wufu continued to squat down, and cleaned up the hard ground at the bottom of the cave, revealing a large gray stone, which was a layer of rammed earth, which was rumored to be made by the ancients with the secret recipe of the Xuan School, which was also mixed with things such as boy urine, glutinous rice, and rooster blood, which was stronger than cement and steel bars.

The hot vinegar was poured on the rammed earth layer, and bursts of white smoke were emitted, as if the water vapor in it was evaporating, Qin Wufu leaned on the corner of the hole in the ground, pinched his nose and did not smell these smells, and after waiting for more than ten minutes, the hot vinegar had basically penetrated into the rammed earth layer, and the reaction was not so violent, so he carried the shovel over.

A shovel went down, the rammed earth layer turned into soft mud, Qin uselessly beckoned Wang Hao to put the box down, and then shoveled the soft mud that had been dissolved by the rammed earth layer into it, tossing back and forth three times, and the layer below the rammed earth layer was cleared out.

He threw the shovel aside, and touched the layer of dirt underneath, which was so soft that he could feel that the surface was covered with a thin layer of tiles, and there were rows of neatly arranged bags inside, which was the second line of defense on the top of the tomb.

Qin uselessly brushed his hand around the glazed tile, it was cold.

A big smile actually appeared on his face, and he touched it back and forth a few more times, and the snow-white rice teeth became bigger and bigger.

"Old Qin, you shouldn't be evil, right?" Wang Hao lay on the top of the cave, and the corners of his mouth twitched.

"Go, go, you've fallen into the devil!" Qin Wufu scolded with a smile, and said with sparkling eyes: "Guess what this is, this is the Diyuan Dansha glazed top, according to the tomb robber faction's Touching Jin Captain, this is at least a Tang Dynasty underground palace below!" I didn't expect that there would be a dungeon in such a poor and remote place, and I didn't run in vain, no loss, no loss! ”

Wang Hao scratched his scalp and asked, "Old Qin, what is Dansha Glass Top, it's the first time I've heard of this kind of thing." ”

Qin Wufu explained while busy working: "There is a kind of Tianbao dragon fire glazed roof, which is a kind of tomb anti-theft measures that only appeared in the Northern Song Dynasty, the tomb roof is laid with a very thin layer of glazed tiles in advance, and the rows of small bags on the tiles are filled with Western Regions dragon oil, and then sealed with glazed tiles and sealing mounds. This kind of glazed tile will be broken by a slight external impact, and the fire dragon oil in the Western Regions will catch fire when it sees the air, and it can burn the tomb robbers to death in an instant.

Before the Northern Song Dynasty, the most commonly used anti-theft measure in the ancient tomb was to lay Dansha glazed tiles on the top of the tomb, because the Dansha glazed tiles and the fire dragon glazed tiles were used for a long time and were tested for a long time, and were the most common anti-theft methods, so the tomb robbers named them Tianbao Dragon Fire Glazed Top and Diyuan Dansha Glazed Top.

The principle of Diyuan Dansha glazed top is similar to that of the Western Regions Fire Dragon Oil, but at that time, the fire dragon oil had not been transmitted from the Western Regions, and the bag was filled with Dansha, that is, mercury. Once the mercury bag is hit by an external force, it will immediately spew out and instantly turn into poisonous gas. Whether it's Western Regions Dragon Oil or Dansha, these neatly arranged pouches rarely get broken at the same time, so they can be triggered multiple times. It was only later that tomb robbers developed a variety of ways to prevent mercury poison gas, so after the Northern Song Dynasty, the Diyuan Dansha glazed top was gradually replaced by the Western Regions dragon oil. ”

At this time, Qin Wufu had already cleaned up the glazed top surface at the bottom of the cave, and pulled the nylon rope tied to his body: "Mouse, look for any sulfur powder in the house." ”

Wang Hao hummed and went out to look for it, Qin Wufu climbed up and lay down on the wooden bed, disgraced.

After a while, Wang Hao returned to the house with a pack of sulfur powder, closed the door again, and the three of them gathered in front of the cave again, and the wolf's eye flashlight illuminated the hole clearly.

Qin Wufu rummaged through his travel bag, took out a black pistol, pulled out the magazine and checked the silver steel ball inside, and reinserted it into the load.

The steel ball gun was bought from the black market by his trust, and it can shoot up to 100 meters away, and can easily burst beer bottles within 25 meters.

Wang Hao sprinkled the sulfur powder from the entrance of the cave according to Qin Wufu's instructions, covering the glazed roof underneath, and later, Qin Wufu instructed A-Ning to find a big box to come over, the kind that was just the size to cover the entrance of the cave.

Bang, bang, bang!

Qin Wufu fired a few shots at the ground hole, and he could hear a popping sound from below, and it was the glass top that was pierced by steel balls.

Qin Wufu put the cardboard box on the hole, pressed it with a shovel, and clapped his hands: "In three hours, let's go down and explore." ”
