Start with a Rolling Beast

"That's right, absorbing dark elemental crystals based on Xiao Hei's current appearance should be the most suitable choice. However, due to the existence of dark summoned beasts, dark crystals are not allowed to be sold, so they can only be circulated in the black market. Now I only have crystals of fire elements, wind elements, and earth elements. You can choose one yourself."

The talent skill Shadow Strike gave Xiao Hei the ability to appear and disappear. What is lacking now is attack and lethality. Bu Dexing immediately made a choice: "Teacher, I want the fire element crystal."

Master Gray had a childish look on his face: "Bu Dexing, you are very good, and you know what you are lacking." Master Gray took out a red palm-sized crystal, "This is the crystal of the fire element, and it is all mined from the attribute veins."

"Teacher, is this expensive?" "Haha, as a teacher, it doesn't matter if it's expensive or not."

"Thank you, teacher." Bu Dexing took Xiao Hei to the martial arts arena with the fire element crystal, "Xiao Hei, here you are, do you know how to absorb it?"

Xiao Hei looked at the crystallization of the fire element in front of him, pondered for a while, and swallowed it in one gulp.

"I'll go, Xiao Hei, don't eat indiscriminately. Be careful if you eat something wrong." After the shadow wolf Xiao Hei swallowed the crystal of the fire element, he suddenly rolled all over the ground in pain.

Bu Dexing was so scared that he was nervous, his two major summons had been temporarily sealed, what should he do if something happened to the only remaining contracted beast.

Finally, after struggling for a few minutes, Xiao Hei fell into a deep sleep and was wrapped in a cocoon by the fire element.Bu Dexing took Shadow Wolf back and went to report to Master Gray.

In Master Gray's office, Bu Dexing was telling his teacher exactly what happened when Xiao Hei ate the fire element crystal.

"Wrapped into a cocoon, this is the rhythm of evolution. If it's just a level increase, it won't be like this. This is also a good thing. Although the shadow wolf has a bloodline of an abyss monster, if it does not evolve or mutate, its thin bloodline alone will not have a high level limit. You can wait for it to break out of the cocoon now, and come to me when there is new progress."

Full of expectations, Bu Dexing returned to the dormitory. Among the other three treasures in the 250 dormitory, only Ma Tiantian was in the room, "Third brother, my little black is about to evolve."

"What's the situation, how did you do it?"

When Bu Dexing told about the fire elemental crystal that Master Gray gave, Ma Tiantian was startled: "My dear, Master Gray is so generous. He gave you a piece of elemental crystal. The problem is that it is only for you to evolve a contracted beast. It is really a waste. Second child, do you know how much it costs, a total of [-] magic crystals, and our monthly food expenses are only [-] magic crystals."

Knowing the value of elemental crystals, Bu Dexing respected Master Gray even more in his heart. According to his current savings, he could barely meet his food and clothing. If it weren't for the other three people in the dormitory to help him, he would starve to death. Now he still owes the daytime three thousand magic crystals to compensate for the damage to the martial arts field. Alas, I have a headache. I wish I could go to the wild to hunt monsters and sell them for money.

In the next few days, when the summoned beasts could not be summoned, apart from the theory class, Bu Dexing would go to the training room to practice the wind saber technique. What should I use to practice, alas, only a small wooden knife can be used.

As for Yuan Lingjue, under the constant screams, he finally widened seven veins. It really hurts to widen the blood vessels forcibly, but now the speed of his own magic power has accelerated a lot, and all the efforts are worthwhile.
