"I've tried it many times. This dragon skin is very hard. It took me 70% of my spiritual energy to cut off two pieces. These are yours." Ye Yuxi casually threw a cloak at Bai Jinyi.

For the past few days, Bai Jinyi was guarding outside, and Ye Yuxi slowed down the time in the chaotic space by ten times.

Three days outside and a whole month inside, Ye Yuxi barely made two cloaks in such a long time, one can imagine how difficult it was.

Of course, Ye Yuxi spent nearly half of this month recovering her spiritual power.

Bai Jinyi took the cloak casually. Although the dragon skin was very tough, it was extremely light, like a piece of fine silk.

"It's easier for me to think." Bai Jinyi held the things in his hands, knowing that Ye Yuxi must have spent a lot of effort on them.

"Jin Yi, look at this." Ye Yuxi didn't say anything to Bai Jinyi's idea. At the beginning, she and Bai Jinyi had similar ideas, but after she tried it herself, she realized that this way would not work.

With a flash of light in the palm, a milky white light cluster appeared in Ye Yuxi's palm, the whole body was snow white, like jade fat.

Different from the beautiful jade, this ball of white jade fat is not solid, but slowly surges above Ye Yuxi's palm, emitting a strong spiritual energy.

Occasionally, one or two blue arcs will flash across it, which is quite strange.

"This inner alchemy hasn't solidified yet?" Bai Jinyi recognized the source of this "jade fat" at a glance, but in his consciousness, the bone dragon inner alchemy should have already become solid.

Ye Yuxi nodded lightly, "This is the inner alchemy of this earth-level bone dragon. The inner alchemy of the other two black-level bone dragons have all solidified, but this is the only one."

With a flick of Ye Yuxi's jade finger, a streak of white spiritual power pierced towards the inner alchemy. Just as it touched the surface of the inner alchemy, an electric arc suddenly gushed out from inside, directly knocking out that spiritual power.

Such a scene made Bai Jinyi frowned again, how could this inner alchemy defuse the attack by itself? !

This is the first time I've heard of such a thing!

I had never seen such a thing when I killed the earth-level spirit beast Nine Yin Dragon Jiao before.

"Its inner alchemy has undergone a slight mutation. I tried it with the fire of the earth spirit, but it couldn't be refined at all." Ye Yuxi said quite solemnly.

"It seems that there are more mysteries in this bone dragon than we expected. I don't think you need to touch this inner alchemy. Show it to Master Long to see if he knows." Bai Jinyi looked at the flickering electric arc at that time, his voice low .

Ye Yuxi nodded, and suddenly remembered something, lightly swiped her fingertips, and two white figures appeared again, "See if these two inner alchemy can help you."

Floating in front of Ye Yuxi were the inner alchemy of the other two black bone dragons. Compared with the inner alchemy of the earth spirit bone dragon, these two inner alchemy had completely cooled down, floating there the size of a watermelon.

Originally, these two inner alchemy were intended to be cooled down and handed over to the staff of the Qi Mansion to activate the silver boat, but after the inner alchemy was completely cooled, Ye Yuxi discovered that the inner alchemy actually contained some space power!

This discovery instantly caught Ye Yuxi's attention, and this inner alchemy also contained some extremely pure black spiritual power.

Those black spiritual powers were extremely hot, very similar to the black flames that Bai Jinyi had awakened before.

Faintly aware of the extraordinaryness of this inner alchemy, Ye Yuxi kept it.

With a light stroke of Bai Jinyi's palm, an inner alchemy fell into his palm. The moment the two got along, a circle of spiritual power suddenly burst out from the inner alchemy.
