Simulation: Start with one person

"Not talking about the increase in the number of monsters, I'm curious about what sludge you are talking about?"

Ying was intrigued by Yelan's explanation. What kind of sludge could be described as weird?

"That's it..." Ye Lan didn't explain, just pointed to a certain place.

Hearing this, everyone looked in the direction she pointed and could see black and purple mud balls...

It seems like a liquid is flowing, but it is actually a solid. The illusion of flow is caused by the shimmering light on the surface.

There is a strange feeling when I look at it, and I have an intuition that it is a harmful item.

"Wow! It looks so disgusting!" Kuina looked disgusted.

"It's indeed disgusting." Ying agreed. Not only did it look disgusting, it also gave people a disgusting feeling.

"How to deal with this sludge?"

Fang Rui didn't overdo it, but asked Ye Lan for his opinion. After all, it was Liyue's business.

"Just shine it with lumen crystal and it will remove the sludge."

Ye Lan said, "As for the principle, it has not been studied yet."

'principle……'

Fang Rui turned his attention to the Lumen Crystal. In terms of energy fluctuations, it was somewhat similar to the Nail of Cold Sky. It should be the power of a nail inserted in the ground to solve pollution.

Fang Rui did not tell Ye Lan and others about his guess. It was not important information and there was no need to know it.

"Then... let's give it a try!"

Fang Rui looked at the security machine. The Lumen Crystal was installed in the body of the security machine. If it was to be used, it should be used by the security machine...

Since he knew that he was going to enter the giant layer rock abyss, Keqing should have asked the craftsmen to make special modifications.

Just as Fang Rui thought, the security machinery was specially modified to activate the power of the Lumen Crystal.

Under the influence of the diffused light energy, the sludge dissipated at an extremely fast speed.

"It's a bit strange." Kuina said when she saw the sludge dissipating, "It's like encountering a natural enemy."

"A natural enemy? You can also say that..."

Fang Rui echoed that Sky Island and Abyss are indeed hostile.

Speaking of which, Sky Island seems to have a lot to deal with, such as forbidden knowledge and the abyss...

Having said that, there must be factions in the abyss...right?

As he thought about it, Fang Rui's thoughts went astray and he began to speculate about the situation inside the abyss.

Find an opportunity to ask Sora, he should know very well.

Sora had not been in Teyvat recently. There was no way to lift the curse in Teyvat, so he went to other worlds to find it. In short, unlike Ying who was traveling leisurely, Sora was very busy.

The apostles of the abyss wanted to help, but the pollution they carried prevented them from helping.

Therefore, Sora has been acting alone.

"Go ahead!"

The group of people continued to move along the passage, looking at the messy passages and the jagged rock walls.

"It's all dug into a maze, which is a bit outrageous."

"Moreover, the flow of earth veins in the giant rock abyss is quite chaotic. If it were not close to Xumi, the situation would be even more serious."

Ruo Tuo shook his head slowly. He should have stopped the miners in the first place. This mine tunnel was almost reaching Sumeru.

Yelan didn't say anything. She had seen it many times and was used to it.

“The passages look the same, but the light is dark, so it’s easy to get lost!”

Fang Rui lamented that when he was exploring the Rock Abyss, he often got lost...

"Lost? Except for the treasure thief group, no one else would get lost in the Strata Abyss. After all, the dangers of the Strata Abyss are well known. Every time the exploration team of the General Affairs Department moves forward, they are cautious and act in teams. .”

After all, it is an area that is emphasized by immortals and emperors, and Liyue's management is very concerned about it.

"Not necessarily~"

Fang Rui twitched the corner of his mouth slightly when he thought of Yan Fei and others breaking into the giant rock abyss.

"Speaking of which, what is our goal in entering the Strata Abyss this time?"

Chapter 621 Exploring the Strata Abyss

"Explore the specific conditions of the Strata Abyss!"

Ye Lan did not hide it and told the situation directly, "As the mining area with the highest output in Liyue, countless miners work here. After the mining area is blocked, it will have an impact on the lives of these people."

"In addition, Liyue's mineral resources are not found in other countries, and they occupy a major position in traded goods."

Every region has its own minerals with local characteristics, but Liyue is particularly rich in specialties.

"In other words, if there are no problems in the exploration of the stratiform abyss, the mining area will be reopened?"

"That's right." Ye Lan replied calmly. After all, the livelihood of so many miners is at stake. If there are other ways to deal with it, they would also like to open the layered rock abyss later.

Unfortunately, if the establishment of the trade center had not alleviated some of the employment pressure, the Strata Abyss would have opened earlier.

"With just a few of us, it's a lot of work to explore the entire rocky abyss."

Fang Rui is quite aware of how big the Strata Rock Abyss is. It took him a lot of time to light up all the anchor points...

Ruo Tuo didn't say anything. He was the main force in this work.

According to what Zhongli said, the first thing to do is to confirm the dangerous area inside the layered rock abyss, and then block the way to the dangerous area.

As for the safe area, it also needs to be dealt with...

Ruo Tuo cast his gaze to high places. In the open space, buildings with simple structures could be seen everywhere. They were the places where miners dug deeper and built a foothold along the way.

If the miners continue to dig deeper, they will dig out something. It may be an abyss, or it may be siltation of earth veins.

So he needs to deal with that.

The Rock God and the Rock Dragon King have the ability to create ores from elements and can also convert soil into ores.

In short, Ruotuo will use rock elements to fill the layered rock abyss, as for the energy consumed.

Ruotu turned his attention to Fang Rui, and according to his plan, he asked Fang Rui for help. After all, absorbing the energy of the earth's veins would affect Teyvat, so he wanted to see if Fang Rui was willing to help.

If the other party refuses, then the plan to restore the Strata Rock Abyss must be carried out in batches...

Several people walked slowly along the passage, gradually moving away from the area where miners gathered, and came to a quiet area where no one was.

"Pollution is getting worse..." The security machinery equipped with the pollution detection system sounded an alarm. Normal security machinery did not have the function of detecting pollution, but the security machinery was a design provided by the immortal, so it was reasonable to equip it with this system.

"Pollution, there seems to be something going on ahead." Fang Rui looked towards the dark place.

"I'm going to investigate..." Mandrill clenched his weapon and immediately prepared a wind wheel.

The next second he was stopped by Fang Rui, "Don't worry, let's go together, or do you think it's safer to go alone than us going together?"

Feeling Fang Rui's gaze, Mandrill didn't say anything. After all, Fang Rui's strength was very powerful, and he couldn't say that it was safer to act alone.

"I... didn't mean that." Mandrill squeezed out a few words from his mouth to show that he didn't have that kind of intention.

"I know what you're thinking, but it's not necessary."

Fang Rui comforted Mandrill. Mandrill had a very direct personality. If you think about it on the bright side, you can guess what he will do.

"Yes." Mandrill did not continue to say anything.

Silence returned to the team, and after advancing for a while, everyone came to an open area.

The direction everyone is heading is from the main mining area of ​​the Strata Rock Abyss to the mining tunnel next to the temporary main mining tunnel.

The mine tunnel is narrow, with a pile of wooden pillars supporting the rock wall. A simple mine car track is laid on the ground. After advancing for a certain distance, you will enter a relatively spacious space with a pool of sludge.

Compared with what I met before, it is darker and wider...

"It's really disgusting to watch."

Fang Rui complained, and the others nodded in agreement.

"If you want to clean up such a wide range of sludge, a little light may not be enough..."

"Anyway, let's give it a try first!"

The security machinery entered the sludge, and the light bloomed. The sludge subsided a little, but it recovered within a few seconds.

"It seems that the Lumen Crystal cannot be eliminated, so let me add some energy."

Fang Rui stretched out his hand and poured energy into the security machinery. The lumen crystal suddenly emitted a brighter light. The large sludge quickly subsided, and the color of the land became normal.

"Ruo Tuo, remember to seal this place."

Fang Rui stared at the ground. In his field of vision, there was a hole here...

The sludge gushes out from here. It is not a normal hole, but a space-type hole, connected to a special space.

Perhaps the holes are relatively small and not much sludge can leak out.

"it is good!"

After leaving the mine tunnel, Ruotuo blocked the mine tunnel and sealed the location where the sludge previously existed.

Having been with Emperor Yanwang and the immortals for so long, Ruotuo has mastered many skills.

After passing through the mine tunnel, the group arrived at another, more open space.

At the bottom of the cave, there is an object swimming in the soil and rocks, crushing the hard rocks into fine sand and gravel...

"What is that?" Kuina frowned, it seemed to be a machine...

"I have seen ancient machinery before when I was exploring the Great Strata Abyss, but I have never fought against it..."

Ye Lan explained that her goal in exploring the Strata Abyss was to find out the dangers inside the Strata Abyss, not to eliminate them.

Besides, she doesn't have the strength to eliminate the threats inside the layered rock abyss.

To be more precise, she can't even get close to dangerous areas. After all, the unknown sludge is contaminated.

"Either siege machinery or construction machinery."
