I lowered my head to pack up my things and filled the package again. The bags of three people were now carried by me alone. Even though I was a little dissatisfied, I still had nothing to say.

They had already walked out far away with their flashlights, but they had no choice but to follow them with their wraps on their backs.

The side space is very large. When you shine the flashlight, you can see the road opposite. The road coils around the mountain wall and turns around in circles.

The space is cylindrical, with a huge drop, and the surrounding cliff walls are polished smoothly. If the road is not built, it will be very difficult to continue.

We walked one after another, and the flashlight shone inside like three eyes that could light, sweeping back and forth!

The road was built to two meters wide and three meters high. There were deliberately left on the edges, and there were small steps to build a slope downward.

Along the stone wall, you can also see spider webs clothed on the stone wall. The spider webs are very new and do not have a lot of dust, which proves that they have just been abandoned.

Having a spider web means that there must be air circulation and insect life here. Only when these two conditions are met can spiders survive in such an environment.

Yaomei and the others walked for a while, and suddenly stopped until I got tight. The two of them took the package on me. Yaomei glanced at me, and still snorted coldly and continued to walk silently.

"Just get used to it, just get used to it"

Ah Fei laughed loudly, as if my embarrassment made him very happy, but I was not ready to explain. I was still following my heart and did what I measured correctly. Even though I took a lot of risks and suffered a lot of losses in the future because of my personality, I still thought it was worth it.

When we went down, about halfway down, Xiao Shi suddenly spoke.

"Be careful, there are creatures below, and the humidity is particularly high."

After hearing his words, the depressed atmosphere suddenly became tense. Although Yaomei was still angry, she knew the importance of it, so she consciously retreated back and went with us.

We walked down carefully, about two-thirds of the place, water droplets began to appear on the road, and there were also traces on the stone wall.

The humidity was too high, and there were rivers or hot springs below. I touched the stone wall and pressed my face on it.

The face was cold and very biting. If it weren't for the hot water accumulation on the stone wall, there was only one possibility, "there was a hot spring below."

"Will we meet a volcano?"

Ah Fei shone the light of the flashlight and kept looking down, but the air below was so bad that the flashlight was blurry.

"The possibility is very high. It's already quite far from the ground. It's normal to have volcanoes."

I said in a deep voice.

China is also considered to be many volcanoes, but they are just extinct volcanoes that have not sprayed for billions of years, but it is not ruled out that there is flowing magma in the extinct volcanoes!

But there is a place that seems strange, that is, since there is flowing magma below, why is the stone wall above so cold and bone-black? This is a very unreasonable doubt.

"You will know if you go down and take a look. I hope the things you set up this time will be simpler."

After sighing, we still have to set off. We walked down the stone wall and heard the sound of gurgling after walking a few rounds.

Ah Fei turned the flashlight down again, and finally saw the situation below clearly, and indeed saw the rolling magma.

The magma is divided into small pools, covering the flat ground below, and a clear river slowly flows through the place where the magma is empty.

It is curved, like a thread stringing into it, connecting large and small magma pools.

Water and magma intersect together to create hot air continuously, and the hot air slowly rises. Because the space is too huge, the hot air is dispersed when it rises.

After being cooled by the cold stone walls on the stone walls, water droplets form back to the river below.

"How much manpower did this tomb be dug to this location?"

A Fei sighed that in fact, this cylindrical space should be formed by natural embryos being modified.

Manual excavation is unlikely, after all, the depth is too deep.

"I'll go ahead, you guys follow us, let's go down and take a look."

We continued walking down and circled twice. We came to the flat ground below, and suddenly the heat wave came. Looking at the rolling magma under our feet, we still felt a little sweaty.

The only road is winding and mixed between the river and the magma pool.

The entire road was composed of basalt stones that were cooled and solidified by water. I stretched out my feet and stepped on it. The seemingly solid basalt stone road surface actually swayed slightly.

"I'm afraid there's magma here. If it falls, it will be dead in an instant."

A Fei reached out and pushed a basalt stone. The basalt stone slowly moved away from its original position with his push. Then the water and magma below were exposed. As soon as the basalt stone left, the magma and water immediately cooled down again, and a new basalt stone quickly solidified.

The entire solidification process is in one breath, and it passes in a blink of an eye.

“It’s too fast, not in line with common sense”

I frowned and watched the magma and water solidify. Even if I encountered water, the high-temperature magma should have a very high requirement for water to solidify at such a fast degree.

Thinking of this, I reached out to touch the clear water. My hand just stretched out and only contacted the water surface.

My fingers were frozen instantly, and a thin layer of ice covered my fingers, and at the same time, a biting pain came from my fingers.

It can be seen how cold the water in the river is. When we came down, the stone wall that was close to my face was against the river. No wonder the stone wall is so cold.

"How is such cold water made?"

Yao Mei spoke in confusion. There were really few waters in the world that could be so cold, except in the two polar regions, and they were basically not seen.

"I remember the master said that there is a strange place in the world called Yin and Yang Spring. I saw the situation here, which is very similar to what he described."

A Fei stood up and suddenly stepped onto the black stone. His feet sank, which made Yaomei scream in shock.

However, water immediately surged around the sinking black stone, and the new black stone quickly solidified, barely stabilizing A Fei's weight.

"Huh, I'm scared to death, do you want to die too?"

Seeing that Ah Fei was fine, Yao Mei couldn't help but pat her chest and looked at him with a reproachful look. The complaint in her eyes made Ah Fei smile embarrassedly.

"I just want to try my own ideas."

"You'd better tell us what Yin-Yang Spring is."

I spoke.

"Yeah," Ah Fei nodded, standing on the black trunk stone, new black trunk stones were constantly generated under his feet, and the old black trunk stones continued to sink.

"The so-called Yin-Yang Spring is composed of a Yin River and a Yang River. The two and two intersect each other to form a strange place from one side to the cold and the other to the hot."

"But Yin River has it, where is Yang River? The magma pool here does not seem to have the same situation as you said on a large scale."

I spoke out in confusion. Since it was a Yang River and a Yin River, there should be traces of flow, rather than being surrounded in the pool and waiting for the Yin River to flow in.

"Look at the flow of Yin River"

Ah Fei pointed at the river under his feet, and I looked with the flow, and saw the Yin River under his feet flowing out from the stone slab where we stood and then flowing forward.

"You mean there is flowing magma ahead?"

"Will we go and see if there is any?"

A Fei smiled and said again.

"One person can only walk on this road at a time. I'll go there first, you can hurry up."

After saying that, he moved his feet and jumped towards the opposite side. The road was not normal, about a hundred meters away. A Fei jumped rapidly on it. Under his feet were the frozen black stones. Where he walked, although the frozen stones solidified very quickly, their hardness was still not as high as before.

After A Fei completely passed, he jumped onto the opposite platform, and the demonic charms came out on our side. Just passed one by one. It took us several minutes to get to the opposite side and then when we looked back.

The road behind it is no longer like this.

"Brother, Sister Mei, come and have a look at this"

A Fei suddenly spoke.

Yaomei and I ran over together. The platform we were about five meters long, and a three-meter-high hole was dug in front of us, leading to another space.

After we left the hole, the scene in front of us made my heart shrink suddenly and my pupils spread instantly.

“This place…”

Yaomei also looked at the scenery ahead with a surprised look on her face and spoke in surprise!
Chapter completed!
