Liang Cheng looked at this deep passage again in surprise. The cross-section of this passage is a near-circle, with a diameter of only about one meter. The passage is long, and the depths extend beyond the maximum range that the flashlight can illuminate.

Liang Cheng put his hand on the rock wall, and instantly a cold and slippery touch came from his fingertips, making Liang Cheng's heart tremble slightly.

"It can be seen that there are pythons active in the burrows." Zhao Youyu used a flashlight to illuminate a piece of the ground in the passage, and there were transparent white shells on the ground that glowed with bright light similar to glue solidification, which was a kind of body crystal secreted by the python's body.

Chen Qi loaded the hand weapon with ammunition and held it in his hand vigilantly.

"But don't worry." Zhao Youxuan paused, and then continued, "The temperature in the cave is about fifteen degrees, and it is impossible for snakes to move at will at this temperature. ”

"I doubt it." Chen Qi was still holding the weapon in his hand, and his eyes looked fiercely at this deep passage, "The snake cave must be somewhere in this cave." Moreover, this hole must be a snake's nest.

Liang Cheng gently leaned against the rock wall of the passage, and a cool and cold yin qi gradually eroded Liang Cheng's body. I leaned my head up lightly again, and the fierce cold stung every nerve in Liang Cheng.

"But who will build this cave?" Liang Cheng asked softly, "And who would come to this kind of place to build this kind of hole for pythons." ”

"According to the notations on the rock, it was built about three thousand years ago." Chen Qi touched a rock and said, "The rock has been weathered, and the nicks are very smooth. ”

"If this is a snake's den, there should be an exit." Liang Cheng asked.

Zhao Youyu nodded: "And we have to get out of here as soon as possible, maybe the temperature will rise at dawn tomorrow, if we are still stuck here at that time, it will be troublesome." ”

"Let's go" Chen Qi put his weapon back in his bag and sat up from the ground.

Because the passage was very narrow, we walked slowly in a row with our waists bowed. Zhao Youyu walked in the front with a flashlight, I walked in the middle, and Chen Qi walked in the back.

After walking for a long time, about five minutes, Liang Cheng and the three walked out of this narrow passage. Facing us was a large stone chamber, and this deep passage was a vent-like passage in the walls of the stone chamber.

The passage is high above the ground, about the height of a story. Zhao Youyu shone his surroundings with a flashlight, and jumped down after confirming that it was safe.

"Come down." Zhao You's voice echoed in the empty stone room. Liang Cheng replied and jumped down the passage, a weightless acceleration followed by a shock from the overweight of the soles of his feet, and Liang Cheng stood heavily on the ground of the stone chamber. Chen Qi threw the bag down, and I was startled by a deafening sound of landing, and then Chen Qi jumped to the ground as well.

"It looks like there's a lot of carving on the wall." Zhao Youyu held a flashlight in the dark stone room, and the black shadows of Liang Cheng and the three of them were reflected on the stone wall by the bright light.

Chen Qi took the flashlight in Zhao You's hand and illuminated a stone wall. I saw that the stone wall was densely engraved with mahjong-sized characters, the words were some square words that Liang Cheng couldn't understand, and the words in some places had been weathered to blur, and in the middle of the text was a huge engraving.

It was a very old portrait, with simple lines outlining the face of a strange man with symbols drawn on his face, two eyes that were two deep black holes in the wall, a thin curved line in the man's mouth, and a body made up of several thick, long, twisted lines. Like, like a boa constrictor.

"This should be a hole in the ground." Zhao Youyu said lightly, "According to the pattern of this stone room, this place should be the center. ”

"But what is puzzling is who this cave is built for, and why there is not a single stone plaque." Zhao Youyu continued. Indeed, there was nothing in the empty stone chamber except the symbols on the stone walls.

"Probably, there are other centers." Liang Cheng looked at the strange murals on the stone wall and said. Zhao Youyan nodded and said, "Maybe there will be some mechanism around, let's look for it separately." ”

So Liang Cheng and the three of them groped separately in the stone room, and Liang Cheng's gaze stayed on the giant python in the wall mural, and the two deep holes in the man's face indicated the eyes.

Liang Cheng didn't know where he got the guts, and after hesitating for a moment at these two holes, he put the index finger and middle finger of his right hand into these two deep holes. The hole was very deep, and suddenly, a cold and soft feeling came from Liang Cheng's fingertips!

Is that a cold, slippery thing, anaconda? Liang Cheng was startled, and wanted to stick out his finger in a panic! But a huge suction force made Liang Cheng's fingers clasp in the hole! Liang Cheng screamed in horror!

Zhao Youyu and Chen Qi immediately ran over! A strong light shone on Liang Cheng's body! Liang Cheng's fingers were deeply clasped in the hole of the mural, combined with the painting on the stone wall, as if Liang Cheng was clasping the eyes of this giant python! It's so weird!

At this moment, there was a soft sound, and the suction of his fingers suddenly disappeared, and Liang Cheng hurriedly pulled his fingers out of the stone wall. Thankfully, the fingers weren't too bad. Suddenly, there was a loud bang on the wall, a puff of dust came out of the wall, and several straight lines appeared on the smooth and intact wall, dividing the wall into a stone door, and then the stone door began to rise slowly.

"What an ingenious workmanship." Liang Cheng couldn't help but admire. Indeed, how ingenious it is to be able to make a crack in such a rock wall that is so thin that you can't even feel it if you are groping against the wall! Liang Cheng couldn't help but be even more curious about who such a cave was built for.

Suddenly, a thin sound came from the wall, and a finger-sized python crawled out of the hole that Liang Cheng had just reached into his finger! Liang Cheng looked at my finger with trepidation. The python stared at Liang Cheng and the three of them with eyes the size of mung beans, and let out a slight cry, unaware of its ascent, it straightened up and leaned towards Liang Cheng and the others.

The door gradually shrank into the rock at the top of the stone chamber, and when the little python realized the danger, it was too late, it was fiercely caught in the crack in the stone, and only had time to let out a small hiss before it was cut in two by the stone door, and a dark passage appeared in front of it. Liang Cheng looked at the passage in front of him stupidly, and couldn't help but walk inside.

"Liang Cheng!" Zhao Youyan shouted to stop Liang Cheng. Suddenly, the stone under Liang Cheng's feet collapsed, and a huge wooden spike shot out from the ceiling above his head, plunging straight into the ground from in front of Liang Cheng's eyes!

Zhao Youyu immediately pulled Liang Cheng back and shot at the ceiling with a flashlight. The ceiling was full of dense holes, and the wooden thorns in some of the holes only protruded halfway, while on the ceiling above where Liang Cheng had just stood, the wooden thorns in the holes only had a spike head sticking out.
