As he spoke, he pressed his entire palm on the ground, and the grass that was originally covered on the ground was suddenly pressed out of a pit by him, Liu Shangang probably didn't expect that the grass was empty, he lost his center of gravity on the spot, and leaned forward suddenly.

Fortunately, I was still quick to see him, grabbed his arm, and pulled him up from the ground.

Liu Shangang exhaled briefly and said to me, "There seems to be a hole down there." ”

I didn't talk nonsense, and immediately drew the green steel sword, which was cut off by the grass he was pressing.

Underneath this layer of long grass, there is indeed a hole with a width of about one and a half meters, and in the grass around the hole, a large amount of scattered debris is also visible.

Liu Shangang immediately took the probing mirror and glanced into the cave, and said, "There are blood stains." ”

He tried to go down as he spoke, but I blocked him and let him follow, and then I put my hands on the wall of the cave and began to slide slowly downward.

We don't know how deep this hole is, but we don't have time to think about it so much now, and if we move slowly, Wu Lin and Jidan Dawu will be in a dangerous situation.

As it turned out, I was right in my decision not to jump straight down the hole, the hole was very deep, and as we descended, the air became more and more turbid, and the corpse gas in it became thicker and thicker, and after ten minutes of going down the hole, I already felt that I had difficulty breathing.

At this time, Liu Shangang turned on the flashlight above my head, and he first shook the beam, and I felt that the light was scattered and knew that he had something to say, so I looked up at him.

Liu Shangang took something out of his backpack and shook it at me, since I was in the backlight, I couldn't see what was in his hand, but I understood that he was probably telling me that he was going to throw that thing at me and let me catch it.

I nodded at him, and he flicked his arm and threw it at me, and when I reached for it, I saw that it was an air mask with a headband, which I had used a few times in the past, and there was a button on the side of the mask that could be pressed to send a sound to other people.

I pressed my feet against the wall of the cave to prevent myself from falling, and quickly put on my mask. I looked up at Liu Shangang and Liang Houzai again, and Liu Shangang shook the beam again, and then I continued to slide down.

"Brother Dao, it may be almost the end." Liu Shangang's voice came from the mask, and I let out an "um", slowing down the speed of the slide while increasing the strength in my hand.

Not long after, I suddenly felt that my feet were empty, and my hands immediately increased violently, and at that time, half of my body was already suspended in the air, and I relied on my hands to support the cave wall to keep myself from falling.

I looked down at my feet, and the beam of light shining from Liu Shangang fell about three meters below me, forming a spot of light that was not too big or small.

Liu Shangang shook the flashlight again, and I saw that the light spot under my feet has not become bigger or smaller, which means that about three meters under my feet is a relatively flat ground, without too many potholes and undulations.

I let go of my hand and let my body fall vertically, and the moment my feet touched the ground, I quickly made another cushion.

Liu Shangang landed behind me, because Liu Shangang's backpack was too wide and too big, and he also rubbed the mud from the hole as he fell, some of which were scattered on the ground, and others were directly on the side pocket of the backpack.

He picked up a bit of dirt from his backpack, rubbed it on the tips of his fingers, and turned the light on the mud that he had scattered, and then said to me, "It's been less than three hours since this hole was dug out. ”

Only three hours? In other words, the hole was dug out during the time when the medicinal properties of the sweat pill attacked.

I carefully recalled the location of the cave entrance, and then thought about the location of the tulou, between these two points is the dense cedar forest, even if someone breaks ground here, Wu Lin will not be visible on the side of the small building. But he was such an alert person, someone was digging a hole under his nose, and he didn't even notice it?

Liu Shangang's voice pulled me back from my contemplation: "Why did the sound of running water disappear after I came in?" ”

After he reminded me of this, I noticed that the sound of water I had heard outside the cave had indeed disappeared, and I thought that there was a river vein under the cave that was not too fast, but why did the sound of the water disappear when I got here?

At this time, Liu Shangang brought the scope again, he took advantage of the vision brought to him by the instrument to carefully observe the situation ahead, and after a short time, he took off the scope and stuffed it back into his backpack.

I frowned and looked at Liu Shangang, who also turned his face to me, and his voice came from the mask: "The blood disappeared ten meters away. It's not a cover-up, it's a natural disappearance. Brother Dao, I suspect that there is a dark river with a large flow ahead, and the water vapor raised in the river channel has accumulated in front of it, forming puddles or thin layers of water, where the blood stains have melted. ”

As soon as I nodded, Liu Shangang spoke again: "Brother Dao, the environment in this place is very complicated, do we still want to continue chasing?" In addition, the last direction in which the blood stains spread was towards the altar. ”

Liu Shangang's words made me fall into a brief contemplation again. To chase or not to chase? Chasing, we came in a hurry, not well prepared, but Renqing should be very familiar with the environment here, and it is very dangerous to forcibly catch up. If we don't chase it, now Wu Lin and Jidan Dawu are in Renqing's hands, if we stop pursuing, they may die because of this.

I can't see death without help, and Liu Shangang also said that the last extension of the bloodstain is towards the altar, which means that the place where we are is is likely to be connected to the tomb, and I still suspect that the tomb we are looking for is directly below the altar.

Pursue!

"Chase!" I pressed the button on my mask and briefly answered.

Liang Houzai took out a few evil charms and pasted them on Liu Shangang's back, and I also took out a few pieces of Yang-guarding candy and stuffed them into Liu Shangang's pocket.

Liu Shangang quickly took off his mask and stuffed a piece of Shouyang candy in his mouth first.

After he put on the mask, his brows had been twisted into the word "Chuan", and it seemed that the yarrow in Shouyang sugar had begun to play a role.

I took the lead, Liu Shangang was the backbone, and Liang Houzai was behind, and the three of us lined up in the most commonly used formation, advancing quickly in the direction facing the altar.

Liu Shangang was right, when we walked out of the ten meters, a lot of water appeared under our feet, and the moisture in the air became very heavy. In just a few minutes, a thin layer of water hung from my bare arms.

When I first came in, the space was still very spacious, and the darkness around me could not be seen through at a glance, but as I continued to advance, the space became narrow, and when Liu Shangang shook the flashlight, the beam of light could already sweep the earthen walls on both sides.

The walls seemed to be plastered with a special kind of hard mud, and in many places it looked like it was made in one piece, and in other places there were numerous holes, sharp cracks around the openings, and fragments of tiles scattered on the ground.

As the distance between the left and right became narrower and narrower, this huge space had "collapsed" into a tunnel with a width of only about two meters, Liang Houzai reached out and touched the wall of the road very close to us, and then his voice came from the mask: "It's Tao." ”

I looked at him, and then at the hard mud clinging to the wall.

Liang Houzai continued: "A layer of burnt clay is attached to the wall. Brother Dao, if you look closely, these stones are very strange. ”

After the clay was broken, a large area of soil appeared, and I also found that there were some huge stones in these soils, but in such a dark environment, because the flashlight illuminated everything was black and white, it was difficult for me to see that there were other substances in the soil.

I looked closely at the stones, and I felt that the uneven marks on them looked like some ancient notches, but after years of damp corrosion, I could no longer tell the exact contents of the notches.

I pressed the button on the mask: "Thick load, can you tell what those nicks are about?" ”

Liang Houzai shook his head: "It's hard to tell, but they look like a bunch of long worms entrenched together." You see, all the notches are the same thickness, which is unusual. ”

Liu Shangang: "Why is it unusual? ”

Liang Houzai: "The process of engraving is obviously very rough, but the thickness of the marks must be deliberately consistent, and I always feel that these marks seem to give some kind of hint to people who enter here." ”

I didn't have much energy to study the murals, so I waved to Liu Shangang and Liang Houzai, and motioned for them to move on.

At this time, Liang Houzai's voice appeared in my mask again: "Why is the humidity so heavy here, but we haven't seen the earth river until now, these nicks may be the reason." ”

I pressed the button on the mask: "Thick load, saving people is important, put the nick thing first." ”

After that, Liang Houzai didn't speak again.

When the width of the tunnel was shortened to two meters, it did not change again, and Liu Shangang shone a flashlight above our heads, and the shadows of the roots could be seen at a high place, and we had come to the cedar forest where the mountain god was hiding.

The corpse qi in front of me became very thick, I stopped, let Liu Shangang shake the flashlight, the miserable white beam of light swayed back and forth in the darkness a few times, there was nothing in front, but by the opportunity of his light, I saw that the road ahead was inclined and extended downward.

I looked back at Liu Shangang and Liang Houzai and said, "Be careful." The two of them nodded at the same time.

I'm more worried about Liang Houzai's condition now, and since I saw those nicks on the stone, I thought something was wrong with his state, but it was just a feeling, and I wasn't sure what his problem was.

I was relieved to see him nod at me, turned around, and continued walking.

After a few steps, the road sloped, and due to the heavy moisture, the ground was slippery, so I had to lower my center of gravity and move down the ramp little by little.

But even if we lowered our center of gravity, the overly slippery ground still made it difficult for us to stabilize our body, and several times I slid down like a slide because I didn't step on my feet, and sometimes Liu Shangang or Liang Houzai would accidentally slide like me, and every time the two of them could hit me and push me down for a distance.

Whenever the body slides uncontrollably, we must put force on the waist to prevent ourselves from falling, if we fall in such a place, we can only slide all the way, and the faster we slide, it is impossible to get up again. No one knows what exactly is at the bottom of this ramp, and the uncontrolled slide may only be a dead end.

We moved cautiously for a long distance, and the corpse aura below the ramp first faded slightly, then became more intense at a faster pace.

At this time, Liu Shangang's voice came from the mask: "Brother Dao, something is not right. ”
