Li Lao sat cross-legged on the ground, the Nine Dragons Ding was placed in front of Li Lao, Li Lao took a deep breath and shot an aura at the Nine Dragons Ding in front of him, only to hear a bang, the Nine Dragons in front of him instantly became larger, and became a big Ding more than one meter high, and a majestic and heavy aura fluctuation came from the Big Ding in front of him. Yu Fei's eyes were full of shock, and sure enough, there was still a considerable gap between the real Immortal Pill Furnace and the pseudo Immortal Pill Furnace.

"Go!"

With a soft voice from Li Lao, a transparent cyan flame violently drilled into the Nine Dragons Ding, and as soon as the cyan flame drilled into the Nine Dragons Ding, the Nine Dragons Ding made a roaring sound, and a faint sound of dragon groans came. Immediately after that, the terrifying temperature emanated from the Nine Dragons Ding in front of him, and Yu Feifei's eyes widened violently when he felt this scorching temperature, and he faintly felt that this cyan flame seemed to faintly incinerate everything into nothingness. Seeing the cyan flame in front of him, Yu Fei's eyes were full of curiosity.

Seeing Yu Fei's curious gaze, Li Lao smiled slightly and said: "Little guy! This alchemy is a university question! Different elixirs need to be tempered with different flames! The flame spawned by ordinary immortals is the Samadhi True Fire, and this Samadhi True Fire can incinerate all demonic and ghostly things! And this cyan flame can only be spawned by the Da Luo Jin Immortal powerhouse, and it can burn the void, it just so happens that this water spirit root, fig, and heavenly heart all need this centrifugal heavenly fire to be triggered! Hehe, if you want to talk about it, the material of the Yuan Dan refined by that kid from Dongyou is still what I helped him refine!". Speaking of which, Elder Li's face showed a flash of gloom.

Yu Fei's heart was full of turbulence, he didn't expect that Li Lao and Na Dongyou Jun would have such a relationship, but at this moment, Yu Fei's also relaxed, and he watched Li Lao refining Yuan Dan intently.

The temperature in the Nine Dragons Ding gradually rose, and slowly the entire Nine Dragons Ding was filled with the cyan flames. Li Lao drank softly, and directly used his aura to throw the heart of the Pegasus Demon into the Nine Dragons Ding, and as soon as the heart was thrown into the Nine Dragons Ding, the terrifying energy fluctuations were quickly released from the Nine Dragons Ding. Li Lao's eyes froze violently, and he directly shot a spiritual energy into the Nine Dragons Ding, and as this spiritual energy entered the Nine Dragons Ding, the cyan flames in the Nine Dragons Ding rose violently, completely enveloping the Heavenly Heart. The terrifying temperature suddenly emanated, and in Yu Fei's shocked gaze, the Heavenly Heart melted into a puddle of scarlet liquid at a speed visible to the naked eye.

Seeing the Tianxin that was melted into a scarlet hot liquid, Yu Feiyu's big boss couldn't help but sigh for a while, this big demon really completed his glorious and great mission from life to death! From the very beginning, the two of them entered the sea of clouds and mist, and the first thing they found was the corpse of the big demon in the shape of a heavenly horse, and when he came out, he divided the meat on his body into sections and sold it, and now his heart has become a medicinal material for refining his own elixir, which is really extremely useful! I also owe it to it, Yu Fei thought in his heart, when he has time, he will repair it with a well-dressed mound, and it can be regarded as a decent departure!

However, fortunately, that day the Great Horse Demon had already hung up and didn't know what was going on later, if he knew, Yu Fei estimated that it would have to come out of the underworld and come up and shave two pouts for himself. Just as the thought in Yu Fei's heart flashed, the aura of the Nine Dragons Ding in front of Li Lao fluctuated violently, and the scarlet hot liquid was dragged aside by Li Lao, and the figs were thrown into the Nine Dragons Ding.

As soon as the fig entered the Nine Dragons Ding, Yu Fei suddenly felt an extremely violent aura fluctuation coming, Yu Fei looked at the fig in front of him in shock, he never thought that the seemingly ordinary fig in front of him contained such a violent and ferocious energy. No wonder the ancestor of the Luo family made a big move when he learned that the figs had been robbed! If he was robbed, it was estimated that he would have to kill the other party's lair! This time, the time it took for Li Lao to refine the figs was undoubtedly longer than the time it took to refine the Tianxin, and it took twice as long to completely quench the figs into a puddle of liquid. An extremely pure and terrifying energy emanated from the liquid that the fig had been tempered.

It took nearly an hour or so to continuously refine these two medicinal materials, and in the face of such a terrifying consumption, beads of sweat also appeared on Li Lao's forehead. Two of the two main medicinal materials for refining Yuan Dan have already been refined, and there is still the last Water Spirit Root left. It's just that in the end, the refining of this water spirit root is obviously more difficult to refine than the first two. Li Laogang threw the water spirit root into the Dan furnace, and a strong soft and watery aura fluctuation came out from the water spirit root. As soon as this aura fluctuation full of water artistic conception emanated, the cyan flames that originally filled the entire Dan furnace actually faintly felt like they had been suppressed.

Seeing this scene, Li Lao's expression froze, and he violently shot out two aura fluctuations into the Dan furnace, and the cyan flame that was pressed down by the water artistic conception aura rose violently, but this effect was not too obvious, and the two completely different energies were frozen together, and no one could help anyone for a while. Seeing this, Li Lao continuously sent several spiritual energy fluctuations into the Dan furnace, and the cyan flame that was originally stalemate with the water spirit root instantly rose several feet high, completely covering the water spirit root. The water spirit root has just begun to have a tendency to melt into liquid, and at this time, Li Lao is already sweating profusely, and the aura on his body is weak and weak, and Li Lao, who is only the Yuan Baby, obviously can't withstand such consumption. Seeing this, Yu Fei on the side hurriedly took out a few elixirs from the ring and crushed them beside Li Lao.

The crushed elixir turned into a stream of aura and entered Li Lao's body, supplementing Li Lao's violent consumption, and Li Lao's complexion looked much better. Even so, the difficulty of refining this water spirit root was still beyond Yu Fei's imagination, and it took more than two hours to completely refine it into liquid. When the water spirit root completely turned into a puddle of liquid, Yu Fei and Li Lao invariably breathed a sigh of relief. After the refining of the three-flavor main medicine was completed, the remaining spirit herb elixirs were much easier, and it didn't take long to be quenched into liquid.

Looking at the dozen or so pools of liquid of different colors in the Dan furnace in front of him, Yu Fei's heart tightened, the entire alchemy has reached the last link, and this link is the final fusion. If you are not careful, a failure will be wasted, and a whole furnace of medicinal materials will be turned into ashes.

Li Lao controlled the liquid formed by the ten or so elixirs that were finally refined to fuse together, the medicinal properties of these elixirs were not very strong, and the process of fusing together did not happen too unexpectedly, forming a puddle of brown liquid. Soon, the scarlet hot liquid that Li Lao controlled Tianxin to transform also melted in, and then fused the figs into it. The original brown energy, as the fig fused in, the originally mild brown energy was instantly filled with that violent aura fluctuation. Now only the water spirit root has not been fused into it!

The most difficult step is coming! Fig and Water Spirit Root are full of fire attribute rage, and the other is full of water attribute femininity, these two energies are diametrically opposed, and it is difficult to fuse together!

Even if he was old, at this point, cold sweat broke out slightly on his forehead. I saw that the pool of liquid formed by Li Lao's control of the water spirit root slowly approached the brown liquid, and as soon as the two came into contact, an extremely astonishing energy fluctuation erupted. These two energies collided suddenly, and there was a feeling that water and fire were incompatible, seeing this scene, Yu Fei's breathing stagnated, and the scene he didn't want to see still happened!

"Melt!"

Even Elder Li felt a great resistance appear, and with a loud shout, majestic aura fluctuations erupted violently from Elder Li's body, forcibly controlling these two energies to merge together. The two pools of energy slowly approached together, slowly merging under the forcible control of Elder Li. Halfway through the fusion, the mutation suddenly occurred, and the two energies suddenly erupted into an extremely powerful aura fluctuation. As this aura fluctuation erupted, the entire Jiulong Ding let out a roar, as if it couldn't withstand this energy fluctuation explosion!

Hearing this voice, Yu Fei's heart instantly hung up, and then, the original burst of violent energy disappeared in an instant, followed by a scorched taste, Yu Fei's heart was suddenly cold, did you fail?

asked about this burnt smell, Li Lao's face was not too good!
