As for communicating those materials and stimulating their activity, Yun Yueyao originally thought that it would be difficult, but when she picked up the first spiritual weapon, her face changed, and her eyes also revealed a strange color!

It was an emerald green flying sword, a ruler long, like bamboo but not bamboo, like jade but not jade.

This view is a bit extraordinary, but the black spots on the body of the flying sword are densely covered with different sizes, and the aura is relatively dim, like a large amount of sand and dust wrapped in a piece of beautiful jade, just like a great beauty who has fallen into the country and the city, should have white skin and beautiful appearance, but it is like a body of age spots, which is regrettable.

However, this was not the reason why Yun Yueyao looked weird, it made her look strange because she tried to comprehend those materials, and she found that her own wood-based Heavenly Spirit Root actually helped with this!

This life-like greenery can actually feel the activity of the pill liquid during alchemy, and the current activity of the various materials in the spirit weapon!

Among them, there is a kind of greenhorned lizard's scales that have not been activated at all, and it is simply wrong to put nitrate in it! There is no material here that can be fused with and complement the nitrate, so those nitrate sand has become those impurities of different sizes on the sword, which not only affects the appearance, but also reduces the grade of this flying sword.

Finding the problem, Yun Yueyao began to work on smelting and purification!

Since these two steps have been done hundreds of times, they are already very proficient, and there are no accidents, those impurities, including nitrate, have been smoothly stripped out by Yun Yueyao, and when they are peeled off, there are ripples on the body of the flying sword, Yun Yueyao can feel that after the things that should not appear on the body of the flying sword are stripped away, the flying sword seems to have a pleasure to convey to her!

This is much more interesting than refining magic weapons and mysterious weapons! The pleasure of spiritual weapons seems to have infected her emotions, and at this time she also has a sense of pleasure and accomplishment that reverberates in her heart~!

Until the step of melting the spirit, Yun Yueyao carefully felt the emotions of this spiritual artifact, and further smelted the scales of the green horned lizard, so that it completely turned into a ball of green liquid, which was thinly wrapped on the surface of the flying sword!

For a long time, Yun Yueyao carefully activated the activity of each material in the flying sword, and then removed the deeper impurities in it one by one, until the flying sword was shining brightly, dazzling, and the happy emotions of the flying sword were more clearly conveyed to her!

Yun Yueyao knew that she had succeeded in this step of melting the spirit!

The next thing is to depict the formation, Yun Yueyao is very curious, how many formations can be carved by a single aura? The magic weapon can only depict three formations at most, and the maximum of six formations of the mysterious weapon is the limit, isn't this aura nine?

With such doubts, Yun Yueyao began to condense the formation diagram, when the formation patterns were carved onto the flying sword, she could clearly feel that its spiritual energy was growing, that feeling, as if the game was reading, until the seventh formation was carved on the sword body, this flying sword finally reached the limit of bearing.

At the same time, Yun Yueyao also felt that kind of visual sense as if the reading strip was full, so she gave up carving the eighth formation.

Looking at the flying sword that has been completed, it can only be regarded as a defective product among the spiritual weapons, not even the lowest-level spiritual energy, but now after being reprocessed, it has become a low-level medium-grade spiritual weapon!

At this time, look at the flying sword, the whole body is as transparent as jade, even if it is not driven, it will emit a warm green light, like a piece of fine spiritual jade, and the water head is extremely full!

This is a manifestation of the spiritual weapon's own absorption of the aura of heaven and earth, which shows that it is not good!
