Just when Lan Feng explained to Ding Lin the strangeness of the Heavenly Book World, Qian Ji also frowned, looking at the Heaven and Earth Melting Pot from time to time.

At this time, the cyan flame burning in the furnace was mixed with a little forest white in the middle, this was the Taiyin Divine Fire, and this flame was the only one in the Heavenly Book World.

The flames of the Kyushu region are divided into heavenly fire, earth fire and spiritual fire, and above these flames are a few divine fires, and the current life of the divine fire is unique, and there will never be a second one. Taiyin Divine Fire, with cold attributes, the ancient powers used it as alchemy, and found that it could preserve the medicinal properties of the elixir, but so, it could not play a big role, so that people didn't care much, it can be said that it was the most despised divine fire at that time, and then slowly turned to the refining weapon, and it was the appearance of an artifact that made this flame shine, and the Youquan Sword was the thing of the town faction of today's Jiuxiao Pavilion.

"I don't know if I used it like this, and when that kid understands the effect of this Taiyin Divine Fire, will he be so distressed that he will cry. Chiki muttered.

However, Lan Feng's current state is difficult to understand, as if a person lacks a soul, there is always something to occupy his stronger heart, so that his body is abnormal, as a martial artist, he doesn't even notice it, and thanks to a bone of this spirit devouring beast, he finally has no worries about solving it in this way.

Qianji gritted his teeth, stomped his feet, or threw the bone into it, and everything was left to fate!

The white flame sank into the bone, not even a trace could be seen, but suddenly, the air seemed to become much slower, the seemingly impermanent bone, from white to dark green, while changing color, it also began to slowly melt, but it turned into not a liquid, but a green liquid, which looked even a little crazy, and the green powder was mixed with a lot of wriggling flames.

The whole process lasted about an hour, and it was completed in the sigh of the thousand machine commanders, the original bones have turned into green flames, and the bone refining is to fuse these green flames, and bless them to their own bones, these are not ordinary flames, but the Taiyin Divine Fire is fused with the bones of the spirit devouring beast to refine, using this kind of thing to hone the bones, the power of it can be imagined, but the accompanying pain is not something that ordinary people can endure.

"Boy, okay, let's refine bones here!, I'll protect you and make sure nothing goes wrong. Qianji waved his paws, no matter how he looked at it, he was a little weak-hearted.

As Lan Feng's consciousness returned to his body, Qianji also prepared the materials, and at this time, Feng Shaoqing was still healing, and Lan Feng jumped into the water after saying a few words.

The water was not too deep, but it was extremely cold down there, and Lan Feng's spiritual power shield almost didn't support it.

"It's a good place, let's start here!" Qianji appeared in the outside world, and completely ignored the environment in front of him, as if in the water and in the world of heavenly books.

"Let's get started, what am I going to do?"

"This is what makes bones. Qianji took out the green flames that had been refined before, "I call them the Soul Devouring Flames, all you have to do is swallow all these flames, use your spiritual power to guide it to attach to your bone joints, and it will automatically refine." ”

"It's that simple?" Lan Feng asked.

"That's it... It's that simple!" Chiki pursed his lips, and then didn't open his eyes to look at him.

"How do I feel like there's a ghost in your expression! Is there something you didn't tell me?"

"No, absolutely not. ”

"Why don't you try it for me first?" Lan Feng said as he grabbed Qianji's tail.

"Stinky boy, you let me go, I said it's not okay?"

"Speak quickly!"

"This is made by fusing the bones of the Spirit Devouring Beast with the Divine Fire, think about it yourself, the Spirit Devouring Beast is at least equivalent to the powerhouse of the Yuan Dan Realm, its flesh and blood are full of huge energy, so not to mention the energy in this bone, in addition, although the Taiyin Divine Fire is not highly lethal, it is one of the Divine Flames after all, not to mention the two put together, you still have to use this thing to refine the bones, and the pain is nothing more than the full force of the Yuan Dan Realm powerhouse. ”

"So it's dangerous to refine bones!"

"It's not a danger, it's a life of death. So you have to think about it. Qianji looked disgusted, and this girl grabbed its tail and didn't let go, which was really uncomfortable.

In that case, let's get started!

Lan Feng didn't hesitate, he swallowed those flames in an instant, those flames slowly spread out in his body along the direction of spiritual power, Lan Feng didn't feel any discomfort or abnormality, just carefully guided the flames attached to his bone joints.

"It's a success!" Lan Feng muttered happily as the flames formed a mold outside his bones.

"The beauty you think, the point is here, withdraw the spiritual power!" Before Lan Feng could get happy, he was splashed with a layer of cold water by Qianji.

However, although Lan Feng was unhappy, he continued to do so.

At the moment when the spiritual power was withdrawn, a painful scream suddenly shook the deep water and tumbled, and Lan Feng's face and the skin of his entire body were no longer visible, and the only thing he could see was a bloody figure.

Qian Ji looked at Lan Feng who was struggling, and couldn't help but shudder, thinking that at the beginning, its owner had also tried this bone refining method, but there was no one like Lan Feng who couldn't bear to look at it directly, just like placing a bomb inside his body, as if he was about to be detonated at any time.

Lan Feng's only feeling at this time was that his bones and even his soul were broken, and he had no sensation except for pain.

Time passed by a minute, but Qianji's face became more and more ugly, "It seems that I still underestimate the cultivation of this spirit devouring beast, with such a powerful power, this soul devouring beast is likely to be a powerhouse who has stepped into the three realms of heaven and man with half a foot in his lifetime." At the same time, he was also worried about whether Lan Feng could withstand it, after all, the powerful power of the Spirit Devouring Beast brought not only pain, but also the difficulty of refining, according to the current situation, this difficulty was definitely beyond Lan Feng's bearing. Otherwise, it won't be unrecognizable.

At this time, Lan Feng could clearly feel that his body was shattered layer by layer from the inside out, and even the burning sensation came from the surface of his skin.

Lan Feng endured the pain, he already knew that the power of the "Spirit Devouring Flame" was too domineering, and even this cold deep water could not alleviate that pain.

After a long time, Lan Feng seemed to have become numb, and his mind began to condense, staring closely at those green flames, which jumped on his bones as if they had life.
