The empire's exploitation of spirit ore can be said to be very mature, coupled with the importance of the Yueyun spirit vein, so although it is hundreds of meters underground, there is no discomfort at all.

In addition, the underground roads here are built in all directions, which are very wide, and are full of modern high-tech construction.

However, after following the guide around, Xu Mochao found nothing as expected, as did Xiao Xiao and Lan Feilin.

The work here is not surprising at this result.

After all, they also spent so long to find nothing, even if the trio were specially selected and sent, they were not expected to find a solution in a while, otherwise it would be a bit too godly.

Xu Mochao and the three of them were naturally happy without explanation.

In the following period, Xu Mochao led Xiao Xiao and Lan Feilin to go to the spiritual mine every day.

Lan Feilin also gradually understood Brother Chao's strategy.

To put it bluntly, it's not worth mentioning.

That is, as those professional technicians, they will check the problem here, and if they can find the problem, they will tell Li Wei.

If you can't find it, it's simple, just pat your ass and leave.

Anyway, passing through the submarine cave is Yunzhou's territory, and even if the people here in Yuezhou know that they have been deceived, they can't chase them across the state, right?

However, she still underestimated Xu Mochao.

When she told Xu Mochao about her speculation, Xu Mochao smiled slightly, took out a piece of paper as thin as a cicada's wings from his arms and put it in front of her:

“Look！”

Lan Feilin and Xiao Xiao immediately stepped forward.

"Letter of appointment?"

The two of them were stunned for a moment, and when they saw that Xu Mochao, Lan Feilin, and Xiao Xiao were clearly hired in an official tone on this piece of paper to become the personnel to solve the "large-scale failure of the Yuezhou Portal" incident, the two girls were completely speechless.

"W-When are you?"

Although this piece of paper is as thin as a cicada's wings, it gives the three of them a legitimate identity.

From this moment on, they really become official staff members who solve problems, and they become tool people with tasks.

Obviously, this matter can only be done by Xu Mochao.

"It's the day we were invited to dinner", Xu Mochao put away the letter of appointment and said leisurely, "I called the dean and told me what I thought, and then it was done." ”

What else can Xiao Xiao and Lan Feilin say?

With a good master, you can really do whatever you want.

Today's Xu Mochao has officially become a closed disciple of the old principal of Qingyi School Park, in other words, Lu Li, the dean of the Sword Academy, has become his senior brother.

With this relationship, getting things done is naturally getting twice the result with half the effort.

But even with this identity, if you can't find a problem, it's still a bit painful.

"Don't worry, we'll fix it!"

Xu Mochao said.

"Why?"

Lan Feilin asked puzzledly, and Xiao Xiao also tilted her head to look at him.

"Intuition."

Xu Mochao's answer made the two cry and laugh.

There was no way, seeing Xu Mochao's confident look, the two girls could only start the process of self-study. Let's read the book

Yes, although Brother Chao keeps saying that he has this intuition, the two girls have a very positive view and know the truth of their position deeply.

I used to fool around with the idea, but now that I have an official identity, I have to work in a down-to-earth manner.

In the following period, the staff of the mine watched these three young scholars from Zhongzhou work diligently and run down the mine every day, and they were quite impressed by their professionalism.

Especially those two young girls.

obviously looks so beautiful, but every time he comes out of the ground, he is gray-faced, which makes people feel distressed.

But the fierce-looking man looked much more laid-back.

But here I dare not say or ask.

In this way, the three of them stayed in Yueyun Mountain for fifteen days, but they still couldn't find out what the problem was.

Although Xiao Xiao and Lan Feilin have become amateurs with a full understanding of this aspect through these days, it is useless.

There is a problem that has not been discovered by a master who has been immersed in this area for decades in a state, and if a quick female driver like them can find the problem, then the protagonist's aura is inevitably a little too powerful.

On the other hand, Xu Mochao still looked unhurried, without the slightest hint of urgency.

During this time, the deputy city lord also came twice, and Xu Mochao's answer every time was that he was still searching.

I also learned from others that Xiao Xiao and Lan Feilin were indeed working diligently like old scalpers, and they couldn't say anything.

It was Xu Mochao's actions that made them a little confused.

He went to the mine very few times, but he didn't stay still, and he seemed to run out every day, and he didn't know what he was doing.

A few times Lan Feilin couldn't help but ask, and Xu Mochao's answer was always one sentence:

"Time will answer all your doubts."

In this way, half a month has passed, and there is only less than a week left before Xiao Xiao's start of school, and even when the city lord Li Wei couldn't help but come here, Xu Mochao, who had been paddling, finally made a move.

"You're going underground with us today?"

When Lan Feilin and Xiao Xiao were about to go to the spirit mine as before, they were stopped by Xu Mochao.

The two of them looked at each other, and they both felt very strange.

For Xu Mochao's paddling, they were also a little helpless.

But they also knew in their hearts that it didn't matter who said what Xu Mochao decided, so even though Brother Chao ran out every day, they just went to check the problem step by step.

Not to mention, although the aura of the protagonist of the two girls is not powerful enough, but when they become one, there is really a little progress.

For example, they now know that the reason why the spiritual power cannot reach the various portals in Yuezhou is that in addition to the blockage of the passages mentioned by the masters, there is also a reason for soil erosion.

This is a different concept from being clogged.

Once this reason is identified, it is equivalent to opening up a new line of thought, and it is likely to be a turning point.

However, it is only speculation by the two at the moment.

After all, as a new driver for a month, the two girls are still a little unsure.

"Yes, I'll go with you today."

Xu Mochao said as he put one arm around one, and walked into the ground with the two girls in the envious eyes of the onlookers.

The three of them chatted as they walked, and Xu Mochao also learned from them about their ideas for solving the problem.

Xu Mochao gave full affirmation to this, and then asked them to take themselves to several suspicious locations where there are currently blocked passages or soil erosion, and remember them one by one.

Then he touched the **, "It's time to show the real technology!" ”
