But seeing Zi Li's palm lightly move, the bone wings in front of him fell down, and finally Zi Li held it with one hand, and the place where he started was cold, and there was a faint temperature in the cold, like a piece of warm jade, giving people a very comfortable touch.

Holding the bone wing in front of him with both hands, Zi Li played with it for a while, and then threw the bone wing into the air, and with a palm of his hand, a cluster of fiery red flames suddenly burst out of his palm, and finally broke away from the control of his palm, appeared in front of him, and slowly suspended in mid-air.

The soul power controlled the temperature of the flames, and after a while, Zi Li stretched out his hand, and the bone wings that were originally suspended in mid-air were directly thrown into the large fiery red flames.

As the bone wings were thrown in, the fiery red flames suddenly popped and suddenly rose, and a terrifying temperature spread out, smoking the entire stone cave like an oven.

Zi Li stared intently at the bone wings under the scorching temperature of the flames, and with the increase in temperature, a trace of gray breath that was imperceptible to the naked eye emanated from the bone wings with a sneer, and finally evaporated and dissipated under the high temperature.

"Tsk...... I didn't expect that there was still a trace of residual aura in the bone wings......" Zi Li looked at the gray aura that kept coming out, a trace of surprise flashed in her eyes, and finally she couldn't help but shake her head in amazement and whispered.

While speaking, Zi Li did not hesitate at all, her hands trembled, and she controlled the temperature of the flame to continue to rise......

And as the temperature of the flame increased, within a moment, the speed at which the gray aura in the bone wings came out gradually slowed down, obviously, under the terrifying high temperature of the Chaos Lotus Heart Flame, the residual aura hidden in the bone wings had been gradually forced out.

After baking at such a high temperature, about an hour or so, when the last trace of gray breath was expelled from the bone wings, Zi Li also slowly breathed a sigh of relief, looking at the bone wings in front of him with full eyes.

However, after the remnant of the breath was removed, Zi Li did not withdraw the flame like this, but carefully controlled the flame at a constant temperature, and Xuan Xuan continued to bake the bone wings.

After half an hour of continuous baking, the bone wings that had been motionless finally made a slight change, only to see a drop of viscous jade-colored liquid suddenly and quietly fall on the originally crystal clear surface, and this drop of liquid did not dissipate like this, but stayed in the flames, slowly tumbling.

As the first drop of jade-colored liquid appeared, it was like a chain reaction, and a steady stream of jade-colored liquid began to seep out of the bone wings, and finally with a subtle ticking sound, it slowly fell.

When the incense stick was tightened, a small ditch about half an inch deep was formed under the bone wing, and on the other hand, the entire volume of the bone wing was nearly doubled......

The change in the bone wings did not surprise Zi Li, but she saw that her eyes were flat, and her handprints were constantly controlling the temperature of the flames, keeping the temperature above a constant temperature, not rising or decreasing......

With the passage of time, the volume of the bone wings is getting smaller and smaller, and the jade-colored liquid underneath it is becoming more and more, and it is becoming more and more viscous and rich......

"Tick!"

A subtle and crisp sound suddenly sounded in the stone cave, Zi Li's slightly narrowed eyes suddenly opened, raised his eyes slightly, but found that the bone wings in the flames had completely disappeared, replaced by a viscous jade-colored liquid, and it seemed that because the temperature of the flame was too high, small bubbles appeared in the puddle of jade-colored liquid, and as the bubbles rose and exploded, a strange energy was also released......

Looking at the jade-colored liquid, the corners of Zi Li's mouth slowly rose, and he breathed a sigh of relief, after refining for so long, it was finally refined into a liquid!

If it weren't for Zi Li's Chaos Lotus Heart Flame, such a flame against the sky, I am afraid that this time would have to be extended for several days.

The heart moved slightly, the fiery red flame in front of him, the temperature suddenly rose, and Zi Li's face gradually became solemn, the palm of his hand turned over suddenly, and more than a dozen white bones appeared in his hand in an instant, and then Zi Li threw it at the flame, and these bones were thrown straight into the flames.

Then, there was a low thunderous sound from the flames, and as the thunder continued to sound, the bones gradually turned into white powder, merging into the jade-colored liquid.

The white bone of Nasen is a kind of thunder attribute monster bone, because the bone wing originally had a trace of thunder attribute, at this time, putting some powder can also make the flying wing have a certain amplification effect after it is formed, and even, if it encounters some thunderstorms, it can be the effect of the thunder attribute energy between the jade heaven and the earth echoing each other, thus making the speed faster!

After putting the bones into the liquid roar, Zi Li successively put some herbs, feathers, and other things into the flames, and the input of these things can increase the flight speed and performance of the flying wing to a certain extent!

In about half an hour, when Zi Li put all the things into the flame and refined them into the jade-colored liquid, the originally crystal clear liquid also became more Aki richer, and there were some stripes of different colors mixed in it, which looked very good!

Looking at the liquid that had changed in color, Zi Li slowly exhaled a breath, but his palm was flipping, and the temperature of the flame in front of him suddenly began to slowly decrease, and in the process of lowering, he would pause slightly for a while.

Looking at the flame exuding a mild temperature in front of him, Zi Li was also relieved, and for the next period of time, there was no need for Zi Li to deliberately pay attention, just guard the flame in front of him and ensure that the temperature of the flame remained unchanged, just fine!

This period of time is considered to be a period of warm recuperation, and Zi Li only needs to wait quietly for the moment when the flying wings are formed!

As Zi Li slowly closed her eyes, the cave fell silent again, only the fiery red flame in mid-air slowly burned, and the subtle sound of bubbles quietly exploding in the flames.

The time of gestation is nearly a day and a night, and Zi Li is also helpless for this time, but fortunately, she is also fully prepared for this, and there is nothing surprising.
