Ji Yunshuang stood in front of the podium and watched quietly, very satisfied with the effect.

"Alright, be quiet."

Feeling that it was almost over, Ji Yunshuang solemnly shouted to stop.

Sure enough, in the next second, the classroom fell silent, and they were all looking at him directly, waiting for his next content.

Ji Yunshuang was very satisfied with their performance, smiled and said, "I know that the students are very interested in the spirit stone, although the mentor I can't show you the real spirit stone itself, but I can show you the projection of the spirit stone."

Sure enough, when they heard that they could take a look at the image of the spirit stone, the students became more and more energetic.

The corners of Ji Yunshuang's mouth hooked, directly lifted the watch, rummaged in the watch for a while, and then pressed his fingertips, and a blue light curtain appeared in front of everyone.

At the same time, the students were stunned for a moment, and their eyes stared directly at the yellow stone in the middle of the light curtain.

Sure enough, as Mentor Ji said, it was crystal clear, like a jade diamond.

"This yellow stone is an earth-based spar, its size is as shown in the picture, it is about the size of a palm, and it is considered large in the spirit stone. Looking at its color, it is bright and yellow, and the purity is very high, which belongs to the best spirit stone. It can be used as a currency for a large sum of money, as well as for making defensive weapons. It is estimated that it is not a problem to defend against a nuclear bomb."

Ji Yunshuang slowly explained the stone, and the students also listened very carefully.

But at the end of the conversation, especially the phrase "defend against a nuclear bomb", the students couldn't help but gasp.

"Nuclear bombs?! Such a small stone can defend against a nuclear bomb?!"

Some of the students questioned it, apparently not convinced.

And there are many who don't believe in it as much as he does, so to speak.

They all looked at him, and the doubts and curiosity in their eyes made Ji Yunshuang open her mouth!

There is such a thing in her space, and it can also be used to prove that what she said is true.

But she just didn't want to.

She's already discovered that if she shows something good, she'll be remembered right away!

Although she has a lot of space for this thing, she doesn't want to give it.

Therefore, she looked at the questioning eyes of her classmates, "Of course, these are all recorded in ancient books, and there is no way to verify them now."

With that, she turned off her watch, letting the hedron disappear before their eyes.

The classmates were a little reluctant to see her turn off her watch, and wanted to take a second look at the legendary spar.

"Mentor, what kind of place does such a golden stone usually appear?!"

It was the classmate sitting at the back who stood up and asked seriously.

Ji Yunshuang glanced at him, this person she remembered, had a pair of eyes that she was particularly familiar with.

"What's your name?!" She didn't answer the rhetorical question.

"Tsukikawa."

He replied, his eyes still searching for the question he had just asked.

Knowing his name, Ji Yunshuang thought for a moment, and did not have any connection with any former deceased?

Could this familiarity be just an illusion?!

Ji Yunshuang raised her eyes, looked at him again, and replied, "The spirit stone, as the name suggests, contains spiritual energy inside its stone. And this kind of stone that can be used to contain aura is naturally a place with abundant aura. Most of them are in beautiful places."

After speaking, she also looked at him silently, the implication was that there was still a problem?

Yuechuan paused, presumably digesting what he said, and after a moment, he asked, "Is there still a place like this now?"

Ji Yunshuang shook her head and sighed, "No."

At the same time, the students in the class also made a series of regrets.

"Okay, okay, this is just the only way for the times to develop, there is nothing to be sorry about."

Ji Yunshuang spoke up again, interrupting their wailing.

At the same time, the end of class announcement sounded outside, and the class came to an end.

"Okay, I'll give you an assignment, and tomorrow each of you will bring a piece of ore, and explain their properties and uses. Class."

After speaking, Ji Yunshuang walked to the outside of the classroom, but the moment she went out, she glanced back at Yuechuan, who was slowly sitting, and felt that his interest in spirit stones was a little unusually enthusiastic.

When she got out of the classroom, she went straight to the cafeteria, anyway, she only had one class a day, and the rest of the time was just enough to go to the cafeteria to watch.

It's just that she was halfway to the road when she saw Dole, who happened to be heading to the cafeteria.

Dole was pleasantly surprised to see her, and walked up to her side respectfully, "Mentor Ji."

Ji Yunshuang smiled and said, "This is going to the cafeteria? Don't you have a class in the morning?!"

Doler scratched his head in embarrassment and said, "There's one more lesson, at half-past ten. I have time now, so I want to see if there is anything I can help with."

Ji Yunshuang nodded again, and then asked, "Did Duoan tell you?" The cafeteria wants to recruit some people, and I plan to recruit them from the students of the academy."

Doeller nodded, "Anyway, the students in our dormitory are willing to work part-time, and a few students who are better at playing are also asking me."

After finishing speaking, he looked at her dressed as a young man next to him, and said, "I know that Mentor Ji doesn't want us brothers to be separated, so he transferred Duo'an to this cafeteria. For this, I am really grateful to Mentor Ji, if it wasn't for meeting you, Mentor Ji, we would not be where we are today."

His eyes were full of gratitude and his tone was sincere, but Ji Yunshuang waved his hand indifferently.

"Don't say that, I didn't do anything, it's just that I need it, you just can provide it, it's equal and mutually beneficial, I'm not as great as you say, you don't have to lower your own figure, otherwise what is the amount of effort you put in?!"

Doler didn't expect her to say such a thing, and looked at her with surprise and instruction, and finally bowed deeply.

"Thank you Mentor Ji for your guidance, Dole has been taught."

Ji Yunshuang smiled, didn't say anything, and continued to walk towards the cafeteria.

When they arrived at the cafeteria, Xiao Kai and the others had already begun to paint the walls and paste the wall panels.

It's just that the color of the wall panel this time is green, a light shade of green, which gives people a refreshing feeling, which is very suitable for the energetic students of the college.

Xiao Kai seemed to be very busy, he kept on the communication, and when he saw her coming, he just waved and said hello, and then went to talk about the communication by himself.

However, in the content of his communication, Ji Yunshuang heard what rock slabs, what stone steel plates, and a lot of things.

Ji Yunshuang has enough trust in Xiao Kai, so she didn't personally ask about these messy things.

Turning his head to look at Doran, he didn't know what he was doing when he was writing and drawing? His brother was also pointing beside him, and the two of them were still discussing it for a while.
