Under the medicine pod, the flames burned fiercely, and the sloppy old man's eyes stared intently, and then used his spiritual power to sense the temperature of the medicine pod.

Different pills have different requirements for temperature, which requires a high degree of experience to be able to grasp accurately.

In the process of alchemy, if there is negligence, it will cause the precious herbs to turn into ashes.

Yechen walked to the front of the medicine tripod in such an open manner, standing beside the sloppy old man.

The sloppy old man didn't notice that there was an extra person beside him, maybe it was his confidence in the formation he had laid out, or maybe he was in the depths of Jiangyin Academy, and no one dared to disturb him.

As time slowly passed, the old man began to put the herbs into the medicine pod, feeling that the flames were somewhat insufficient, the sloppy old man hurriedly squatted down and went to the bottom of the medicine pod to add the fire source stone.

After carefully placing the position of the fire source stone with the iron tongs, the sloppy old man suddenly found that there was an extra pair of feet beside him.

The sloppy old man was slightly stunned, and then suddenly looked up and saw Yechen standing aside and smiling at him, the old man's eyes suddenly widened, and a thick anger immediately appeared on his face.

"Boy, where did you come from? The sloppy old man said angrily, the power on his body instantly surged, and Yechen found that this sloppy old man was still a master, and his strength was only half a step away from stepping into the martial spirit, presumably the high-level in Jiangyin Academy.

However, for Yechen, the scum of the martial artist or something, he could not arouse his interest at all, and he was far less attractive to him than the medicine tripod in front of him.

Yechen said: "The temperature is up, quickly put in the herbs." ”

The sloppy old man was a spirit, and he couldn't blame Yechen anymore, and after glancing at Yechen viciously, the old man carefully put the Seven Star Frost Leaf Grass in his hand into the medicine pod.

Then, the silver power in the old man's hand emerged, constantly pinching the pill and punching the power into the medicine tripod.

Alchemy is divided into, refining, purifying and becoming a pill.

Refining is to refine the essence of the herbs, leaving the useful parts and removing the useless parts.

The second part of purification, which is further strengthened, is more difficult than the previous refining.

The last step is to fuse all the purified herb essences together, which is the simplest step and the most important step.

For each step, there is a corresponding recipe, the experience that needs to be accumulated, and the perception of the way of alchemy.

Now the sloppy old man is the first step, refining.

The old man's movements are decent, but Yechen can see that this old man is very pious about the way of alchemy, although his clothes are sloppy, but in alchemy, he is very delicate, but he is only hindered by his talent, so he has to be so careful in refining a furnace of Lingluo Pill.

After about an hour, the first step of refining was finally completed, and the sloppy old man was already sweating profusely. There is a pile of white powder left in the pod, and these are the essence parts after removing impurities.

And in this process, he didn't have time to look up at Yechen.

Next, the second step is purification.

The sloppy old man continued to put the pill recipe into the white powder in a regular manner, while maintaining the temperature of the medicine pod, while further purifying the white powder, and the remaining part will be less than one-tenth.

Yechen watched silently from the side, watching the sloppy old man's "clumsy" movements, and felt pity for this superb seven-star frost leaf grass in his heart.

The higher the age of the herb, the more difficult it is to purify, and seeing the sloppy old man's sweaty appearance, Yechen was afraid that he would destroy this elixir.

Suddenly, the white powder suddenly made a "snort" sound, and the old man's face changed.

This is a sign that the elixir is about to be scrapped.

The old man sighed in his heart, such a superb seven-star frost leaf grass, originally he didn't dare to refine it alone, but he couldn't resist the temptation of the best frost leaf grass, and in the end, he didn't wait for the helper to come, and started refining alone.

And he didn't grasp the medicine powder that was intact before, and now the medicine powder is about to be scrapped, how can he save it? According to his previous experience, the old man knew that most of this superb seven-star frost leaf grass had been scrapped by himself, and the next half was irretrievable.

This time, the alchemy has failed.

"It's all the boy's fault. The old man suddenly remembered the young man who appeared inexplicably beside him, and he was furious in his heart, and secretly said that if he hadn't appeared and distracted himself, this alchemy might have succeeded.

The old man didn't want to continue alchemy, he turned his head angrily, the anger in his heart wanted to vent, that young man was the best outlet for the fire.

However, when the old man turned his head, he froze.

Yechen's hands kept forming handprints, which were the elixirs of alchemy, and his tanjue was completely different from the danjue he had seen.

This set of pill recipes seems to be more complicated, but between the complex movements, the young man's movements are like flowing clouds, and he is not unfamiliar at all.

The old man's eyes looked at all this blankly, for him, who had been immersed in the pill all his life and was infinitely devout to the alchemy, the young man's movements were almost like the Tao, so that the old man could not find the slightest flaw.

And the powder below, under the young man's pill technique, began to beat constantly, and the part of the essence of the pill was constantly peeled out again, and the powder that was about to be damaged was being purified normally at this moment.

No, it's not normal at all, the old man found that the speed of this purification was three times the speed of his own purification.

The old man was already stunned, completely immersed in the alchemy skills of Yechen's art, staring intently at all this. It wasn't until two hours later that Yechen finally pinched a pill harvesting formula, and with bursts of fresh medicinal fragrance, white pills were beating in the medicine pod, and the old man reacted that the alchemy was over.

Subsequently, the old man's face showed a thick and incredible expression, the thirty-one pills in the medicine pod at the moment were ten more than he imagined, and these Lingluo Pills were all superb, their medicinal effects were at least twice that of ordinary Lingluo Pills, if they were refined by themselves, even if they were lucky, they would only be about twenty, and the medicinal effect would be one and a half times that of ordinary Lingluo Pills.

How can there be such ingenious skills in this world?

When this thought just came to the old man's mind, he saw Yechen pick up the cold ice jade bottle that the old man had prepared, and put the thirty-one pills into the two jade bottles, one of which Yechen unceremoniously stuffed into his arms, and the other in the sluggish old man's hand.

Then, Yechen, who was in a good mood, turned around and left.
