Qian Rujun walked up the ramp, and finally reached the top of the cave.

The space on the top of the cave was not very open, and the thinnest person in Qian Rujun's group could barely get into it, but Qian Rujun found that it was clear how the water came from here, as well as the golden object that the students below said.

It turned out that the roof of the cave was not a flat surface, but like limestone, it was eroded out of pit after pit, and this pit was constantly leaking.

At the bottom, it was the rain that hit people and hurt a lot.

When Qian Rujun was approaching the top of the cave, he looked out from a pit.

It's easy to see the golden object.

The students of Gakudo Island poked their heads out and took the initiative to touch these objects, and found that the objects were powdery, but very hard, and it could be said that they were almost consolidated on them.

However, Qian Rujun can notice that the water droplets are transparent and colorless when they are on the upper layer, and do not contain a special fragrance, but when they pass through the golden powdery object, they are contaminated with the golden object itself.

The golden object itself, for a long time, has been eroded by flowing water, and some of it is dissolved in the water, although only a little bit each time. But the downward-flowing water has already been affected a little.

"Go down there and dig some golden stones. Qian Rujun made a request.

The students of Xuetang Island, seeing that Qian Rujun was not named, rushed down in a swarm, wanting to be the first to mine the stone.

The reason why Qian Rujun did not designate a candidate was because she found that she didn't know how many people would be needed to reach out and dig the stone down, or what method they would come up with, so she took a reserved attitude.

He knew that the students of Xuetang Island would always come up with a way in the end, and it was estimated that one person would not be able to do it.

Sure enough, within a few minutes, the following students began to discuss.

They all have some equipment on them, and for collecting this kind of thing, because the original purpose is to collect ginseng, everyone has some collection tools in their hands, so Qian Rujun did not take the initiative to provide tools.

However, if a student on Gakudo Island asks her for it, she will give her tools according to his request.

But it's clear that students don't need tools.

The students of Xuetang Island prepare almost all of the tools they have designed with excellent products. In the case of knives and shovels, both have telescopic functions, it should be said that knives and shovels are basically different only in the head, and the telescopic rod at the back is the same.

They designed multi-functional tools that would be used in later generations.

They tested the hardness of the stone with a shovel and found that the stone was actually very soft after a long period of erosion.

To dig, it doesn't take much effort.

So a few of them divided their positions and began to dig, and soon the things were delivered to Qian Rujun.

This kind of unknown object that the e-paper book does not understand, Qian Rujun naturally has to get the score table in the e-paper book.

Qian Rujun put it on the points, and it took a long time for the points, and finally came out that these golden stones can be exchanged for points, and there are only five points for each gram.

But Qian Rujun took a look, but the amount was huge, if he could get all the yellow substances in his hands, it would be worth hundreds of thousands of years of ginseng.

It was easy for Qian Rujun to make a decision.

Dig.

However, it can't rely on the ten of them, Qian Rujun knew that there was not much danger in the process of coming in, so he asked one person to notify the people outside. After performing the task of ginseng, he came in and started mining.

Maybe the waitress of the e-paper book said it very well, when she has to do it alone, now there are 900 people, in fact, many things have become relatively simple.

But it's also a big problem, there is not enough space in this place!

"Princess, we have a way, you can go and wait outside, or see what the people who study the land have to know." You might be able to find what you're looking for. ”

"Okay, then I'm out. You've really solved a lot of problems. ”

"Yes. ”

Qian Rujun didn't ask much, turned his head and walked out, comparatively, it would take a long time to get to the place where they were studying.

Qian Rujun was only halfway through when he found that the rain in the sky had stopped.

She looked back in the direction of the students, only to see that they had left, no longer where they were, but the figure of the student appeared above her.

This student also waved to her, looking very playful.

Qian Rujun gradually gave way to the students. I think they're familiar and so on. Still, she couldn't match the name with the student's appearance.

If only face blindness could be cured so easily.

Qian Rujun walked to the group of students who were left behind, who were packing up their things and preparing to go over to support.

"How's it going?" asked Qian Rujun.

"It was found to be a special substance that was able to absorb water instantly. But further, it is not known. ”

One of the students rubbed his head in embarrassment.

They stayed and studied for so long, and only that came to them. I was a little embarrassed to face Qian Rujun.

Qian Rujun didn't care very much, but he was quite curious about the water absorption of the following things.

Now, the rain in the sky has stopped, and only a curtain of rain has formed at the entrance to the cave.

The water is still quite large.

What caught Qian Rujun's attention the most was that under the rain curtain, although the water would splash out, there was still no excess water left on the ground.

That's what really piqued her interest.

Seeing that the students were packing up their things and going up to help, Qian Rujun didn't want the students to stay here.

The matter of mining has made the students take the lead, so she might as well come and study the underground things.

However, Qian Rujun has a head, and she herself knows that it is not suitable for research.

It should be said that Qian Rujun's associative power is not very good, and it is rare for the idea of association to appear in Qian Rujun's head. She can only analyze the reality of the situation, which is partly her strength.

For a leader, in fact, she doesn't need to know everything, but the name of the dean always makes her feel that she can't be looked down upon.

When you were the only one left, she grabbed a handful of dirt from the ground...... She called it dirt, she felt as if the things on the ground were a whole piece, and when she grabbed it, the whole surface seemed to be lifted up by her, and there was no way to separate them.

A thought flashed through Qian Rujun's mind, could it be that this surface is not an ore or soil, but a plant?

But this plant has no branches and leaves?

Soon, Qian Rujun had a new idea, because this part of the bottom plate she grabbed gradually generated a kind of power, as if it was about to get out of her control.

Qian Rujun felt very curious and let go slightly.

In an instant, the ground was flat again, as if nothing had changed.
