When they finally stood in the crystal cave that Shi Miye mentioned, everyone was infuriated.

Even without touching the crystal, the high-density energy flow is stimulating the energy in everyone's body to increase.

"Awesome! This kind of high-purity energy crystal can be sold at a good price even if it is just one! I have never seen such a pure crystal before!" Lucas' eyes shined.

Energy crystal, as the name suggests, is a crystal that stores energy from different element attributes. It is the most important material for people to assist in practice in this world. By absorbing and converting the energy in the crystal into magic or fighting energy, one can quickly improve one's own strength, and the purity of the crystal determines the mass of the energy absorbed.

Although many people understand that true masters often do not rely too much on this external practice method, the sales of Energy Crystals are quite good in places like St. Glace Academy where you have to use your strength to decide the next year's class every year.

"I didn't expect that there would be such a large crystal mine in the mountains near the academy! But why did no one discover it before?" Pandora asked curiously.

"Maybe no one noticed that energy crystals grew in the mountain when the school was built. Even if someone noticed it, it would be difficult to open the talk of developing crystal mines because the college was built here. But this also made us get a bargain, right?" Teacher Duolun speculated.

In the afternoon, after returning from the cave, the two teachers went directly to the store to apply for a stall. Although it was located in a corner that was not very eye-catching, when the teacher walked into the classroom with a permit, it still caused a burst of cheers.

"Because the teacher cannot do any business in the hypermarket, this license will be handed over to Lucas in the magic class for safekeeping in the future. Any transactions will be handed over to Lucas in full responsibility. Do you have any opinions?" Duolen asked loudly.

"Teacher, I can't do it! Although my family is in business, I'm not good at this aspect at all!" Although Lucas saw that everyone had no objection, he still refused in a panic.

"but……"

"It's really not possible! I'm not suitable to be the person in charge!" Lucas interrupted Doron firmly.

"But... But, Luke is the only one among all of us who knows the profession, right? No matter how well or not, it should be better than us laymen! Besides... Besides... you are our class monitor." Luo Jielinti's beautiful face was blushed, and she looked at Lucas with a little shyness.

Lucas almost spurted his nose bleeding, and he was incoherent: "Okay, okay, I... I know, I accept it."

Everyone laughed when they saw this.

In the next few days, apart from visiting schools and collecting energy crystals in the mines, the rest is teaching time.

Although Shi Miya asked Pandora about how to practice the regular magic circuit, for a long time, because no one guided him to practice the magic circuit that most mages practiced, his magic circuit was different from others. Moreover, in this situation where he had already established, it was already difficult to establish an orthodox magic circuit.

"To re-establish a regular magic circuit, you must destroy the current circuit from scratch, but if you do this, you will not be able to keep up with the progress of others." Pandora told him.

"Although it is impossible to start practicing orthodox again, the progress of continuing to practice the current magic circuit is not obvious." Shi Miye was very clear about his current situation. After thinking about it, he only thought of one way: combine the practice methods of two magic circuits to create a third practice method between the two that will not cause harm to the body and can reasonably utilize various self or external forces.

Although this newly opened practice method does produce some effects, once you practice it to the key points, the magic circuit will have a clear sense of blockage, but it is useless to think about these things now. After all, the solution cannot be imagined in one go.

Let go of these things for the time being. The most important thing now is to deal with the first weekend after coming to St. Glace Academy.

Early in the morning, before the store officially started business, some students from the black class who volunteered to help rushed to the stall in a corner of the second floor to do some preparations.

When the store was about to open, the stall was almost cleaned up, and the goods were all placed on the counter. Each crystal was packed in a finely made metal box. This was done by Lucas, Major and Moya desperately. The entire dark system only had the profession of the three of them suitable for such fine work.

"Hmph, what three people did! Although your partner is skilled, he ran away halfway through it!" Major closed the book with a "splash", and his tone was a little angry.
