Crossing the Collapsed Iron and Rebuilding Yalilo

Arriving at the temporary camp built by the miners, Xia Zhihui found that they all had ropes tied around their waists, and the ropes were tied together to prevent someone from slipping and falling and being washed away by the current.

Xier found two more ropes from the pile of supplies nearby and threw them to the two men.

"Come, tie yours too."

Xia Zhihui took it, tied it for Hu Ke, and put the remaining one back.

"I won't tie it. Let Hook and the hole machine take you back. The hole machine has enough kinetic energy."

"What about you?"

The water was still flowing into the depths of the new mine tunnel, and there was no sign of water accumulation.

"

I will follow the mine tunnel to see the depths.

"You're not going to die, what's so good about it?"

"Listen to me, Hill."

"We initially thought that the lower area was like a pocket, and this rain was like a faucet, pouring water into the pocket continuously, so we were worried about the problem of water accumulation and flooding."

"But now the lower area is more like a sink for washing hands. The faucet is constantly releasing water. There is an unknown water outlet deep in the mine tunnel. It looks quite large."

"Although this rain was brought by the giant star mud brick, I am not sure when it will stop."

"I have to go and see how much water the reservoir deep in the mine can hold, so that I can prepare for what's next."

What he said made sense, and Xier gritted her teeth.

"Then I'll accompany you"

"No, I won't drown in the water. When I fall into the water, I will teleport back to the town. You may not be faster than me." After he said this, Xier stopped forcing

"Okay, then you must be careful"

"Hook, let's go. You lead the way and I'll be the rear guard. Everyone watch your step and don't miss any opportunities!"

Watching them gradually leave, Xia Zhihui smiled, took out a hammer pepper from the system backpack and stuffed it into his mouth. He had been soaking in the water for almost four hours, and it was a bit cold, so he wanted something exciting.

After adding weights to himself, Xia Zhihui continued to walk down the mine tunnel.

Mine tunnel collapses are not uncommon, so miners will do their best to take safety measures in the mine.

Every few steps he took, he could see the steel beams above his head supporting the mine, but as he went deeper, the steel beams above his head gradually decreased, the depth of the accumulated water under his feet gradually increased, and the water flow became more and more turbulent, rushing towards the depths of the mine.

After an unknown amount of arduous trek, Xia Zhihui finally reached the end of the mine.

There were no signs of further excavation here, and there was accumulated water.

But the accumulated water was surging, forming a vortex in the middle, and constantly flowing to an unknown place below.

What should I do?

After thinking about it, he closed his eyes and made up his mind. , took a deep breath and dived down.

The whirlpool was like a blender, driving Xia Zhihui to keep spinning in the water. He felt dizzy and wanted to vomit.

But not long after, he flew out, rolled on the ground, and was washed away for a long time before he got up.

There was the sound of water roaring around, the earth's marrow was exposed, and fungi and mosses grew everywhere. Even without turning on the flashlight, he could see clearly.

This is an underground river.

He was now on the river bank. The olm that was originally licking the moss leisurely next to him was scared by him and fled around with its teeth and claws bared.

The road behind him was a hole in the wall that was washed open by the accumulated water.

At this time, there was still a steady stream of accumulated water flowing into the river.

With the light of the earth's marrow, he could even vaguely see small fish jumping.

Xia Zhihui clapped his hands.

Damn! Why didn't I put a fishing rod in the system backpack!

Oh, there is no such sport as fishing in the lower area, because there is no river in the lower area, and the water used is taken from snow.

That's okay, they are all air force anyway.

"No wonder there are so many vegetation ecosystems in the lower-level mines, and even amphibians like cave salamanders. It turns out there is such a large underground river!"

"Now even the snow in the lower area can be explained. It is caused by the overall water cycle and low temperature. I wonder if the protection of the Amber King is also a driving factor."

Soon, Xia Zhihui noticed the most important point.

"There is still so much exposed earth marrow around. If it is developed well, I don’t know how long it can be used!"

On both sides of the dark river, the earth marrow is like stones on the riverside. You can see many pieces at a glance.

And the place where he is now is just a section of the dark river. He doesn't know how much more there is upstream and downstream.

He picked up a piece of earth marrow and weighed it, put it into the system space, and planned to go back to let the miners judge the purity.

At the intersection of the flowing water in the lower area and the river water, fish kept jumping and jumping, as if provoking.

Xia Zhihui couldn't stand it now. It's just that there is no fishing rod. I'll take the clothes pocket!

The heavy rain stopped suddenly in the fifth hour of pouring, and the dark clouds dissipated as if they had never appeared.

The last accumulated water in each town is still flowing to the large mining area.

At the gate of the large mining area, a group of people tied together with ropes saw familiar faces.

Xia Zhihui was wearing short-sleeved shorts, barefoot, and soaked. At his feet was a package wrapped in a raincoat, which was bulging and moved from time to time.

Xier came from the end of the team and asked

"How long have you been waiting?"

"In less than ten minutes, I tell you, it's really fun down there."

"Fun?"

Xier raised her eyebrows. When did you become like Hook?

She stretched out her hand to twist the soft flesh on Xia Zhihui's waist, but was nimbly avoided and even slapped.

"Look, this is my catch below."

Confused? What confused?

Xi'er looked at Xia Zhihui with a puzzled look as he untied his raincoat. Inside, there were densely packed fish struggling.

The small ones were only as long as a finger joint, while the big ones were as long as an arm.

Xi'er looked at the strange-looking fish and hesitated for a moment.

"This fish..."

Xia Zhihui was puzzled

"What's wrong? Aren't you happy to have fish to eat?"

"Why are there no eyes?"

"Because there is no light below, it is not needed, so it degenerates"

"Then why is it so ugly, and even has a protruding forehead?"

"Scientifically speaking, it is a highly sensitive organelle that evolved to detect water pressure, temperature, salinity and flow direction."

"What about the unscientific statement?"

"Anyway, in the underground river, no one can see it, so just let it grow as long as you want."

For a moment, Xier didn't know where to start.

"Are you sure you can eat it?"

"I am sure, because I saw the olm hunting. We have been eating olm meat for so long and nothing happened, so this fish must be fine too."

Okay, I can't refute it.

Xier wanted to confirm it again, but suddenly she realized

"Underground river!"

"Yes, the fish caught in the river"

"We must report to Natasha immediately and check other mines!"

Xia Zhihui shook his head.

"No rush, I think the big mine needs to be reorganized in the next two days."

"But now, I'm going to go back and make soup."

Speaking of going back to the cafeteria to make soup, he suddenly thought of the little guy who came with him.

Hook was still hanging on the hole in the fuselage.

"Hook, remember to go back on time for dinner, we're having a big feast today!"

"Great! Hole Machine, take off!"

Before the Hole Machine transformed, Xi'er and Xia Zhihui said in unison:

"No flying around!"
