"Commander Sun, do you still have white vinegar?" Fatty Wang was originally going to take out a mountaineering pickaxe, shovel and other objects to make holes, but he found that the dead silver on the ground was so filthy and solid. With one hammer, only a white dot was left.

"I'm in trouble now. I just used up all the white vinegar." Sun Guofu waved his hand helplessly.

"Hey, wait, something is wrong here!" Fatty Wang suddenly muttered, then squatted down.

I saw a gap as thick as a finger on the originally thick and tight rock wall floor. The surroundings were dark and the visibility was not high, so Fatty Wang did not notice it at the first time.

After finding this gap, Fatty Wang took out the saber, inserted it into the gap with force, swung his arm, and pried it a few times. After trying several different directions, the three of them heard a "click" sound! The sound came from under the stone wall.

Immediately afterwards, a series of sounds came from under the stone wall, and the direction of the sound was still moving, as if it was spreading from the soles of the feet to both sides.

"I heard this sound, it should be a trap hidden weapon like the flip-flop in the ancient tomb. But here is clearly a ghost island, with the ground tightly fit, so how could a flip-flop trap appear? It's strange!" Sun Guofu muttered, then walked up to check it out carefully.

But at this moment, the ground where the three of them stood, about five meters long, and the entire rectangular floor, turned over. The three of them were caught off guard and all were hit.

After the floor flipped over, a huge black hole appeared, and the three of them fell directly from the hole.

"Damn, is it really fun?" Fatty Wang screamed, and then asked the two to pull up their backpacks and put them under their butt. Because after the three of them fell into the hole, they did not fall straight, but slipped downwards, as if they fell into a very steep passage downwards. The reason for placing the backpacks under their butt was to act as a buffer when they encountered obstacles later, so as not to hurt their little brother and other key parts.

But the tragic thing is that the passage is square, and when it slides down the road, it is inevitable to bump. There are countless places on the head, shoulders, and knees of the three of them have been broken. Moreover, the dark passage is steeper than 45 degrees, and the three of them feel that they are almost falling all the way.

After a full minute, the three of them screamed all the way, rolled out of the passage, and fell heavily into a slippery place.

It was a stone platform, about five or six square meters in size. When the three of them fell out of the corridor, they slid directly to the edge of the stone platform. Fortunately, the three of them reacted very quickly, and they each held the stone platform firmly with their hands, so they did not fall down from the stone platform.

"Grandma, Li Mengfan, this turtle grandson, had known that we would chase him, so he left us a trick!" Fatty Wang fell so hard, but he still stood up and looked around.

I saw that there was a height of about three or four meters below the edge of this small stone platform. However, under the stone platform, there were precious lights everywhere, colorful and exquisite, reflecting many beautiful phantoms, just like a river of heaven.

"Underground River?" Zhang Xingkuo also lay down and asked, touching his waist that was hurt by falling.

"It's not the river." Sun Guofu's face suddenly became ugly: "It's the Milky Way, the Three Life Yellow Spring River used to rebirth in the tomb."

Zhang Xingkuo unscrewed a flashlight and shook it around. The mercury under the platform was shined by the lights, and it reflected a lot of colorful light, which looked extremely gorgeous.

I saw that this was a square secret room, about two acres of land. Looking up, the ceiling of this secret room is flat, about seven or eight meters high from the foot. It is covered with strokes of the 18-layer hell flavor, such as the evil spirits, the sea of ​​swords, the sea of ​​fire, the Avici Hell, and the eighteen layers of hell-style strokes.

However, on the ground, this secret room was divided into countless platforms of different sizes. Each platform was crisscrossing gullies. Below the gullies, mercury flowed, and it was bottomless. It was like this was a mercury lakeside, and on the lake, each platform was like an isolated island.

The three of them are located at the left corner of the square secret room. In front is a dense platform, and behind is the passage where they fell down.

"The air here is toxic. We should not stay for a long time. Find a way out quickly." Sun Guofu said.

"Then there is a way. I think we should go back and go out of the channel that fell down." Fatty Wang said. But when he looked back, the corridor where the three of them fell out had disappeared completely, and there was no trace left.

"This place is really weird. Brother Zhang, I will be a ladder for you. You can climb to the top of the secret room to take a look. Anyway, the air here will not be poisoned for a while, so we can leave from above." After saying that, Fatty Wang was about to squat down and lift Zhang Xingkuo, but at this moment, the sound of flowing water suddenly came from all around.

The three of them changed their faces when they heard the sound and rushed to another edge of the platform. Sure enough, there were countless holes lined up in rows on the walls around the secret room. The big ones were as thick as buckets, the small ones were as thick as arms, and the number was very large.

At this time, mercury was flowing out of these holes, and the sounds the three of them heard came from there.

Mercury poured down, flowing into this secret room, and pouring into the gully lakes under the platform. Not only that, as the mercury flowed out of the holes, the mercury under the stone platform was also slowly rising. That is to say, the mercury poured out of the holes on the surrounding stone walls was filling the secret room bit by bit. It seemed that it would take about one or two hours, and the mercury below would flood the entire stone pillar.

"This is the most common mechanism for burying the scholars in the tombs! When we fell down, the surrounding mechanisms had already started. And this secret room had no exit. If you want to survive, you can only find the valve for the mercury catharsis outlet in these platforms." Sun Guofu thought for a moment and then said.

"What thing? Valve? This thing also has switch control?" Fatty Wang muttered.

"The mercury that appears here was reserved by ancient people in large quantities here. However, no matter how much reserves are, it cannot be endless. Therefore, there must be a mechanism for recycling, and there must be a drain valve at the bottom of this secret room." Sun Guofu said again.

"One, two, three, four, five... There are eighty-one stone platforms in total. You can get out of the way. Fatty, I will test a stone platform in ten seconds and find the valve switch in minutes." Fatty Wang shouted proudly.

However, as soon as he finished speaking, the stone platform where the three of them were located began to sink, as if there was a bloody mouth slowly swallowing it.
Chapter completed!
