When the smell of many medicinal herbs mixed together came out, the three of them couldn't help but cover their noses all of a sudden, with a look of horror.

This...... This is clearly exactly the same as the scene of Le Kai's first refining, could it be that this kid failed again?

Le Kai has no time to care about the minds of the three of them, at this moment, his eyes seem to be flat, but in fact, he has been fully powered, completely locked the Dan furnace, although separated by the hot mist and bronze body, but the situation in the Dan furnace is as transparent, and the slightest change has not escaped his perception.

Just when the Wu brothers and sisters were about to retreat away from the pungent smell of medicine, they saw Le Kai open the small Ding furnace that he had taken out of his arms, uncover the lid, and elegantly drip a few drops of liquid into it like pouring wine.

Sneer......

Like sulfuric acid poured on the floor, as soon as the crystal liquid entered the Dan furnace, it triggered a series of chemical reactions, first a burst of white smoke, and then it seemed to be purified.

What's even more amazing is that the original pungent smell of medicine has suddenly undergone an astonishing reversal, and in the turn of breath, it has turned into a fragrant fragrance.

"This ...... Is this the real alchemy?" Wu Yitian was taken aback, as a worldly peak martial artist, he was infinitely close to the final threshold, and naturally felt the abnormal changes in the air. It's like there's a huge suction, sucking in the aura around you!

Generally speaking, the aura cannot be seen or touched, but it is real, just like the mysterious essence contained in the mineral, which cannot be distinguished by the naked eye, but it is the essence of the mineral.

There was a sudden change in Le Kai's eyes, as if a calm deep pool was thrown into a boulder, and instantly splashed a circle of ripples, which seemed strange and unpredictable, and the invisible qi machine seemed to turn into substance, enveloping the mouth of the Dan furnace.

I only heard his low scolding, like the dark sound of spring thunder, low and heavy, his hands suddenly opened, the wind whirred, between his ten fingers, an air mass suddenly emerged, although he was in the basement, but at this moment, the three of them were like being in the turbulent sea, feeling shaken, trembling, as if the whole world was dancing with the ten fingers of Lekai.

The world is spinning, time and space are reversed!

"Rambo, close your eyes and don't look!"

Le Kai shouted in a low voice, beads of sweat appeared on his forehead, how huge the true qi that had been accumulated for two months gushed out, completely beyond his expectations, and instantly triggered the surrounding qi, almost out of control. Even with his powerful spiritual power, it is like a whirlpool at the moment, as long as it touches it, it will be deeply attracted, and it will be difficult to break free.

Wu Zhitian had already pulled up his stunned sister, withdrew from the five battles like lightning, and looked at Le Kai in horror, although he had been constantly overestimating Le Kai, but at this moment, he still found that it was far from enough, this kind of momentum, this kind of oppression, was really too far beyond himself.

Le Kai no longer has reservations, the spiritual power and true qi are all at full strength, within a radius of five zhang, they are all extremely dangerous areas, the whirlpool generated by the true qi, frantically absorbing the thin spiritual energy around him, and then spinning, submerged into the Dan furnace.

This is the most crucial step in refining the "Qi Returning Pill", and the power of the pill is completely determined by the amount of True Qi that can be infused and retained at the moment.

The mist disappeared, and the strange fragrance was no longer smellable, and all the qiē were controlled by Le Kai, and the final fusion was carried out in the Dan furnace. This fusion requires an incomparably subtle control force, and there is no room for the slightest mistake, and it is indeed a milestone-like test for the alchemist.

The aura in the basement was already extremely thin, but after a while, the absorption speed slowed down, and the movement became smaller and smaller, and finally calmed down.

Le Kai's eyes are changing, there is no focus in the curtains, but like two cameras, they are constantly changing, and the spiritual power is transmitted out, and the final step is to perfectly control the true qi, that is, divide the medicinal liquid into one by one and seal it up, otherwise, the essence will go away with the wind, and work in vain.

This is even more a test of the alchemist's spiritual control power, and it is necessary to divide the spiritual power into several strands and use them in one heart.

This invisible danger is the real danger, the slightest carelessness, there is the possibility of injury, and even worse, the brain domain is counterattacked, and it is possible to become neurotic or brain-dead.

What's even more depressing is that this level can only be relied on by oneself, and outsiders can't help at all.

Is it finally the final stage?

Le was happy for a while, but he was extremely depressed, this refining process, he had already rehearsed the "game tactics" in his mind countless times, and he was sure that he was comfortable before he began to make a formal attempt.

It's just that the actual operation is not a drill, Le Kai found that he had miscalculated one thing, that is, the aura of the Azure Star is now thin Cheng dù, and Dan Idiot didn't think of this at all when he made a plan for him, so when Le Kai launched the true qi and spiritual power to collect the aura infusion as expected, this loophole appeared, and it was undetectable in the early stage, but it was revealed in the later stage, that is, the true qi and spiritual power were consumed.

If the pill does not absorb enough aura, it cannot be considered a success, and the price of falling short is too great. Lekai not only needs victory, but also perfect victory, and even the slightest flaw cannot be tolerated. At the end of the moment, there is no doubt that there is still a little bit of heat.

Fight!

Le Kai gritted his teeth, grabbed the copper tripod containing the juice of the "Three-Star Yunling Grass" and poured it into his mouth.

What an absolute waste!

You must know that this furnace pill has added a large number of rare medicinal materials, but the juice of the "three-star Yunling Grass" is only a few drops, and now he uses it as a drink to drink, if he is known by Dan Idiot, he is afraid that he will also jump up and beat his ass.

The absolute gains outweigh the losses.

Le Kai can't tolerate the failure of his "game tactics", as long as he succeeds this time, he will be able to correct his mistakes according to the thick Cheng dù of the surrounding aura when refining in the future, but now, he must succeed.

The "Three-Star Yunling Grass" took three hundred years to grow, and then Lekai used a secret method to refine the essence juice, how could the effect be imagined by ordinary people? Although it was only a small sip, it was enough to refine more than a dozen furnace pills. So much juice was drunk by Le Kai, and the effect can be imagined.

The juice is fragrant, and the spirit in the mouth is a shock, as if a man with kidney deficiency has taken some kind of fierce medicine, and the results are immediate, and he becomes a fierce man in an instant. But then, every drop of that juice was like a small bomb, exploding in Lekai's dantian. With the explosion, the huge aura was like a balloon agitation, and it suddenly propped up, making Le Kai's stomach bulge all of a sudden, and it was extremely round and terrifying.
