Everyone walked cautiously on this spiral staircase, the surface of the staircase was very slippery and difficult to walk.

At first, the surface of the staircase was covered with layers of moss, but as the height dropped and the temperature dropped, the moss was slowly covered with a layer of frost, and even later, the moss was completely frozen in a thin layer of ice.

As the passage dropped, the temperature decreased little by little, and at the beginning, everyone felt very cold, even shivering, but as more and more stairs were completed, everyone gradually became sweaty, and this feeling was very uncomfortable.

The outside is cold air, separated by a thick layer of cotton clothes, but the inside is full of sweat, the sweat sticks to the body is very wet and sticky, and there is no way to discharge it from the body, all of it is covered by the cotton clothes, and now Chen Ziyang only hopes to be able to take a hot bath in the hot water.

"I said Eryang, do you think something is wrong? This spiral staircase is so strange, how can you say that the person who came to collect the treasure could have walked so far? Even if he walked to the bottom of the stairs and retrieved the treasure in the dungeon, would he still walk back down the stairs little by little? This is really the best anti-theft mechanism, and before the treasure can be taken out, people will die of exhaustion inside. Are we on the wrong track? Yang Lei touched the frost on his beard stubble and said jokingly.

"Probably not, although this staircase is difficult to walk, but it is very safe, it should be a passage to the underground palace, the reason why the staircase is so difficult to walk is completely because there are too many years. But I don't understand, since we entered this dungeon, the temperature has not been low, and this is a confined space, but why is it so cold here? ”

No one knows the answer to this question yet, it seems that only after walking this spiral staircase can we know the reason, and at this time, Chen Ziyang's heart has a trace of happiness, he thinks that the reason why it will be cold here is because there will be some cracks and other things under the stairs that can lead to the outside. In this way, cold air comes in, which is why the temperature here is lowered. If that's the case, at least everyone will find the exit first.

From beginning to end, everyone in the team was careful to take out the spirit of 12 points to prevent their feet from slipping and falling. At the beginning, it was okay, and there were no accidents, but as the stairs gradually descended, after a long time, people's physical strength decreased, and mistakes naturally occurred.

The first to make a mistake was Hu Bo, when Hu Bo was walking, he was not paying attention to his feet and fell to the side, and he subconsciously pushed his hand forward, but there was nothing to borrow, so Hu Bo fell down the gap in the stairwell.

Umbrella Shishuai, who was walking behind Hu Bo, saw this scene, he subconsciously stretched out his hand and grabbed Hu Bo, but first, his feet slipped, and there was nothing to borrow, and secondly, when Hu Bo fell down, he pulled Umbrella Shishuai with great strength, so the two fell down together.

At this time, the umbrella stone shuai used the pickaxe of the sapper shovel in his hand to get stuck on the stairs, and a row of serrations on the pickaxe increased the friction between himself and the stairs, and hung the two people in the air.

When the other people saw the scene in front of them, they were scared into a cold sweat and wanted to come forward to help, but because the place was small, there was nothing that could help, but fortunately, the sapper shovel of the umbrella stone was relatively strong and could withstand the weight of two people, and it seemed that the 20,000 yuan was really not spent in vain.

Because the diameter of this staircase space is not very large, so Hu Bo hanging in the air is not very far from the steps under his feet, after the umbrella stone shuai said hello to Hu Bo, he slowly shook up, like a swing, Hu Bo swung in the direction of the stone stairs little by little, after several swings back and forth, Hu Bo was already very close to the opposite steps.

Umbrella Shishuai shouted a slogan, let go with his strength, and took advantage of the force of swinging past to throw Hu Bo on the top of the stone staircase facing down. Hu Bo stood on the stairs, quickly leaned forward to hold on to the wall, shook his body for a few moments, and then stabilized his figure, turned around and gave a thumbs up to Umbrella Shi Shuai, Chen Ziyang saw that after Umbrella Shi Shuai saved Hu Bo, the other team members all threw grateful glances at them.

Just when everyone breathed a sigh of relief, thinking that the two of them would get out of danger safely, at this time, there was a sudden change. The pickaxe on the sapper shovel of the umbrella stone marshal was not actually stuck on the top of the stone staircase, but on the ice on the surface of the staircase.

Originally, this layer of ice was very solid, but as the umbrella stone shuai swayed back and forth, the pickaxe also swiped back and forth on this ice layer slightly, and after a few times, this ice block had already detached from the other parts.

Just when Umbrella Shishuai used his strength to swing Hu Bo over, this piece of ice was completely detached from the surface of the stone ladder under the vigorous pulling, and Umbrella Shishuai only felt that the ordnance shovel in his hand suddenly loosened, and he fell into the space in the middle of the stone staircase with this ordnance shovel.

"Old umbrella!"

"Brother Umbrella!"

Chen Ziyang and Yang Lei subconsciously shouted out, the two of them supported the wall with one hand, leaned down on the other hand, and looked down from the space in the stone staircase, but except for the dark part in the middle, they couldn't see anything else, and they didn't hear the answer of the umbrella stone handsome.

Just when the two of them were anxious and wanted to hurry down to see the situation of Umbrella Shishuai, suddenly they heard the voice of Umbrella Shishuai from the bottom of this stone staircase:

"Oh my God! But it scared me to death, I thought I was going to fall and die here, I'm fine, don't worry, the stairs are at the end, you guys be careful to come down. ”

Hearing the words of the umbrella stone handsome, a few people put their hearts at ease, this is really a big disaster, there must be a blessing, I can't think of the place where the umbrella stone shuai fell, it is already very close to the ground, hearing that the exit is in front, several people quickly quickened their pace and walked the remaining stairs.

The space at the end of the stairs is still very small, and Umbrella Shishuai is lying there, he was not scared just now, and he is lying there to calm down. When Umbrella Shi Shuai fell, he hit the ground right on his back, and the things in the backpack behind him also helped him reduce the impact, and he fell right on top of the backpack without causing much damage to his body.

And the sapper shovel was also lying next to him, seeing the miserable appearance of the umbrella stone handsome, Chen Ziyang and Yang Lei hurried over, one of them took one of his hands, pulled him up, and patted the snow and dust on his body for him.

"Old umbrella, your life is really big enough, this is a good person has a good reward, Lord Yama won't accept you, this is really dangerous." Yang Lei said while helping Umbrella Shi Shuai pat the snow on his body.

"Brother Umbrella, thank you." Hu Bo saw that there was nothing wrong with Umbrella Shishuai, and he was also relieved.

"You're welcome, didn't you save me too."

Just when the two of them were taking care of the umbrella Shi Shuai, Xiao Na and the other team members were watching left and right in this space, the space under the stone staircase was very small, and after more than a dozen people all came down, the place was already crowded.

More than a dozen flashlights illuminated the surroundings, but there was no exit or anything like that. Then Xiao Na found something different, so she shouted to Chen Ziyang:

"Mr. Chen, you come and see here, our passage is really on the right track."

Listening to Xiao Na's words, Chen Ziyang felt very strange, why did Xiao Na say this, why did she think that this passage was correct? Chen Ziyang hurried over to see what Xiao Na had discovered.

Seeing what Xiao Na's flashlight was shining on, Chen Ziyang also had the same idea as her, it seemed that they were really on the right path, because Xiao Na's flashlight at this time was shining on a gear set sunken in the wall like when the golden gear was inlaid outside the dungeon.

In this stone trough recessed in the wall, there are four or five gears around the golden gear in the middle, this golden gear Chen Ziyang is too familiar with, it is definitely the golden gear they used to open the gate of the Bohai Palace before. It seems that under the action of repeated mechanisms, this gear has been spun here.

Chen Ziyang carefully observed this mechanism, it seems that this mechanism has not been opened for a long time, because the frost on these gears is not very thick, and next to these gears, there is a thing like a crocker, although the frost on this joystick is very thick, but Chen Ziyang tried to shake it, and the joystick did not fail.

So Chen Ziyang looked at Xiao Na, and after Xiao Na nodded, he slowly rotated the joystick, and several gears in that groove, driven by the golden gear, slowly rotated with the rotation of the joystick.

With the rotation of the rocker and gear, there was a series of dangdang sounds in the stone wall nearby, and then, there was a gap in the curved wall next to the rocker, and a cold wind blew in it again, this time, this mechanism did not fail, as Chen Ziyang continued to rotate the rocker, the small curved wall slowly retreated outward, and then it was completely opened.

One by one, the people in the group walked in, and behind the stone gate was a stone platform that was not too big, more appropriately like a small pier than a stone platform. Except for this stone platform, all the other places here are filled with water.

Seeing what was behind this semicircular stone gate, Chen Ziyang finally knew why it was cold in the space of this stone step, it turned out that behind this stone wall, there was actually a huge underground pond.

However, under such cold temperatures, the water in the pond did not freeze, but a trace of mist came out of the pond. On the pond grew a huge round leaf-like plant, these leaves were all dark red, each leaf was extremely huge, even the smallest round blade was more than a meter in diameter, and the largest was even two or three meters.

These huge crimson blades are all perfectly round, and the edges of the blades are slightly upturned, and each of them looks like crimson plates floating on the water. Looking at the endless underground pond in front of them, everyone didn't know how to move forward, did they want to build a small boat?

Chen Ziyang squatted on the edge of the stone platform, looked at these plants carefully, and pressed them with his hands from time to time, at this time, I don't know who was stimulated by the cold air here, and suddenly sneezed, and the huge noise frightened everyone, and the same frightened, there were tiny creatures on these leaves.

As this sneeze sounded, yellow points of light flew out on these blades, and then there were more and more points of light, and they were connected into a wall of light, and these points of light flew slowly in the air, and a few of them slowly floated towards Chen Ziyang and others.

At the beginning, everyone was still avoiding these points of light intentionally or unintentionally, afraid that they would cause harm to the human body, but as there were more and more points of light around everyone, a few points of light touched the human body, and nothing happened, so Chen Ziyang quickly stretched out his hand and grabbed a point of light in his hand, he opened his palm and saw that what was in his hand was a firefly.

But this firefly was different from the other fireflies that Chen Ziyang had seen before, this firefly was actually white, and the light coming out of the back of its butt was not green, but slightly yellow.

Chen Ziyang is not a biologist, and he doesn't know what kind of species this is, but as far as he knows, none of the fireflies look like this, so let's call you snow fireflies, Chen Ziyang thought in his heart, can survive in such a cold temperature, and at the same time are still alive, it seems that these fireflies are really hardy.

After letting go of the firefly, Chen Ziyang continued to study the plants on the water, and then he stood up, and with a force of his feet, he jumped onto a leaf. Chen Ziyang's sudden move startled everyone, and Yang Lei exclaimed in surprise, thinking that Chen Ziyang would fall into the water like this.

But a strange scene happened, after Chen Ziyang jumped on this blade, the blade just sank slightly, shook a few times, and then rebounded back, and actually held Chen Ziyang, who was more than 100 catties, on the surface of the water.

Looking at the surprising scene in front of him, Yang Lei opened his mouth into a big O-shape, he couldn't believe his eyes, although this leaf is very large, but after all, it is also a plant, I can't imagine that this kind of leaf can bear such a heavy weight, you must know that Chen Ziyang's weight is more than 130 catties, plus the strength of his jumping just now, it is equivalent to saying that this blade can hold up the weight of nearly 200 catties, which is really amazing.

"Haha, sure enough, it's the same as I guessed, these leaves are the way we are going, these things should belong to a kind of Wang Lian, although I'm not sure, but look at the size of this leaf should be about the same,

Wang Lian is the plant with the largest leaves, and the adult Wang Lian can hold up the weight of sixty or seventy catties, but the diameter of the Wang Lian is generally only more than one meter, this leaf is much larger than the Wang Lian's leaves, and it can naturally hold up heavier weights, and we can step on these leaves to move forward. Chen Ziyang turned back to Xiao Na and said.
