A dim basement in the innermost part of the civilian area welcomed the first guest today, and it was also a distinguished guest, that is, Sun De, who walked behind Yang Yi for nearly ten minutes before Sun De came to this basement that Yang Yi called the research room.

Looking at the empty material cabinet, looking at the dark and damp environment, not to mention studying the magic circle here, if it weren't for seeing if Yang Yi was lying, to understand his curiosity, Sun De wouldn't even have stepped into this basement.

Three grams of land coral powder, five grams of Jonah iron tree, greenstone moss......

As soon as he walked into his house, Yang Yi couldn't wait to recite the recipe of his rapid magic circle solution, Sun Deke was the tutor of the magic circle department of the demigod academy, needless to say that he guided himself, even if he pointed out the deficiencies in his magic circle solution, it was enough for Yang Yi to improve his magic circle solution.

While listening, he nodded, until Yang Yi recited all the materials, Sun De still didn't find any difference, although the one Yang Yi got was indeed a few more materials than the formula of the ordinary rapid array solution, but in terms of efficacy, it was absolutely impossible to compare to the formula of the rapid array solution in the demitheon.

"I'll give you the materials, you help me refine some, and I'll buy it at the auction price. As he spoke, Sun De took out the materials one by one in the storage ring, and soon filled Yangyi's material cabinet, which even included more than two hundred high-grade magic crystals and a few one-tailed demon beast magic crystals.

These things are like garbage to Sun De, just because he brought his students to the Burial Forest to exercise, while explaining the efficacy and hidden properties of these materials, and at the same time storing these things in his storage ring, which made him, a demigod realm magic circle master, simply become a garbage recycling station.

Yang Yi was very happy to get enough materials to refine two rapid magic crystal solutions for no reason, but what made him even happier was that in addition to more than two hundred high-grade magic crystal stones, there were also several one-tailed demon beast magic crystals, these magic crystals Yang Yi had seen countless times in the auction house, but there has never been a luxury item purchased by high-grade magic crystals, although he has not yet had the ability to refine other magic crystal solutions, nor has he had a formula, but he has always accumulated materials in this way, otherwise it will be time-consuming to wait until he really buys a magic circle map of other magic circles, and then it will be time-consuming to get the materials。

With a hint of excitement, Yang Yi urged out the true yuan in his body and ignited the raging fire.

Three grams of land coral powder, five grams of Jonah iron tree, greenstone moss......

As more materials are put in, the color of the flame changes dramatically, and it is difficult to distinguish between them and various types of light.

Yang Yi was very calm, as soon as he started refining the magic circle solution, he completely forgot everything about the outside world, and there were only flames in his eyes, only those brilliant colors.

Looking at Yang Yi, who was engrossed and had even forgotten about himself, Sun De nodded with satisfaction, as a magic circle master, he knew that only by being engrossed in the magic circle master could he observe every color change and observe the release of every trace of power of the flames, and only in this way could he refine a high-purity magic circle solution and keep the failure rate at a very low standard.

The flames suddenly changed from softness to rage, and the color of the center of the flames gradually turned white.

Yang Yi was more careful at this time, lest he not grasp the heat well and make these materials wasted.

Yang Yi didn't move, Sun De didn't dare to move, the magic circle master was the most vulnerable to disturbance at this time, once he was disturbed, the material was wasted, and the refining solution failed to be said, if the last triggering solution was put into the wrong dose at the wrong time, it would not be a simple failure at that time to be able to end.

Yang Yi didn't move, Sun De didn't move, but they all ignored the other creature in the room, a little monkey, this monkey was adopted by Yang Yi by chance, because it was not a demon beast, Yang Yi also regarded it as his friend, after all, in this strange place, Yang Yi was still very lonely sometimes, and when he missed his family, the little monkey was the best partner.

It's just that today, the little monkey who has been listless and sleeps all day suddenly sat up energetically when Yang Yi had just started refining the magic circle, and his eyes were full of wisdom no less than that of human beings.

Just when the flame in front of Yang Yi gradually turned blue-white, and was about to turn white completely, when the initiator of the emerald stone solution was introduced, the little monkey moved, and moved quickly.

I saw the little monkey jump in one by one, and almost came to Yangyi's material cabinet by accident, and its speed made Sun De on the side a little surprised.

Glancing at Sun De slyly, the little monkey reached out and picked up a piece of magic crystal, and at the same moment when Yang Yi poured the prepared emerald stone solution into the flames, the little monkey quickly threw the magic crystal, mixed it in the emerald stone solution and rushed into the flames together.

Boom!

Almost at the same time as the magic crystal and emerald stone solution rushed into the flames, the intense flames burst out in an instant, and a huge fireball wrapped all the solutions and suspended in the air, out of Yang Yi's control.

The little monkey suddenly changed his appearance at this time, and returned to Yang Yi's back in a state of despair, as if it was not him at all just now.

Staring at the white flames tightly, Yang Yi didn't dare to relax even more,

The magic crystal quickly vaporized in the flames, and under the initiation of the emerald stone solution, the gas formed by the magic crystal continued to expand, and then expanded, and it would not take long to get out of the flames, and at the same time as he departed, it was when the fireball completely collapsed, and a big disaster was inevitable.

Stone Shield!

As a demigod realm magic circle master, of course Sun De saw this dangerous situation at this time, although he had the intention to save Yang Yi, but he himself may not be able to protect himself, in desperation, Sun De took out a dark yellow magic circle, and drew out his demigod vitality to ignite it,

Rumble!

In an instant, more than a dozen stone walls with a thickness of nearly one meter quickly became angry underground, and the entire basement was completely filled in an instant, surrounding Yang Yi and Natu flames in the middle.

Return to liquid, return to liquid.

Looking at the vaporized magic crystal, Yang Yi prayed helplessly, he knew that only when the magic crystal returned to the liquid, it was possible to mix it with the solution of other materials, no matter what kind of solution was to be formed, or simply failed, it was much better than bursting.

A miracle happened, under Yang Yi's prayer, those expanding magic crystal gases seemed to touch an invisible big hand, shrinking, shrinking, shrinking again, Yang Yi could clearly feel the speed of these magic crystal gases shrinking.

And Yang Yi didn't know that this big hand that made the magic crystal gas shrink was the translucent filament that connected his eyebrows and the solution, and it was also this filament that kept the flame burning, otherwise before the magic crystal solution burst open, the flame would have disappeared by itself.
