Lin Chongtian didn't rest for a moment, as all the herbs disappeared in front of him and sank to the bottom of the furnace, the purple-red light of Lin Chongtian's hands disappeared immediately. But it was only for a moment, and then it immediately turned into a lilac light, and the transition was smooth and not awkward at all. It's just that compared to the original bright fuchsia, this lilac glow is slightly grayer.

"The fifth step is to cool down. If it is too cold, it will volatilize some of the medicinal essence, if it is too hot, it will evaporate part of the herbal essence that has reached the highest temperature, and if it is hot and cold, then the herbal essence will not be able to withstand the capricious changes and lose its aura. Only by maintaining a certain uniform temperature can the herb essence be left with the most perfect and complete medicinal surname, preparing for the final step of the great fusion. ”

And this so-called uniform temperature regulation completely depends on the level of alchemy of an alchemist himself. Lin Yongtai said expressionlessly, "This step is the last step before closing, if you think about it too simply, then you are wrong." Once the temperature is not well controlled, then all the work done before will be wasted, and many alchemists often relax their vigilance after experiencing a complicated period of alchemy, and as a result, the ship capsizes here.

Lin Nantian nodded, how could he not know that except for the most critical fourth step, the seemingly ordinary fifth step was a trap that was not big or small, when he first learned to refine medicine in the early stage, the person who stepped on this trap at that time was probably no less than the one who failed in the most critical fourth step, even he himself had accidentally made a mistake.

However, obviously, the experienced Lin Chongtian would not capsize in the gutter here, and he calmly controlled the water element force to cool these newly extracted herb essences, they were like carefree elves, dancing and running to their heart's content in the spacious incinerator furnace. Obviously, the current temperature is more suitable for the survival of these plant essences, and it does not make them feel any resistance and discomfort.

As the water element power continued to cool, the inside of the incinerator gradually stabilized, and the small world inside gradually became quiet, and the medicinal herb essence was like a group of children who were tired of playing asleep. At this time, Lin Chongtian unhurriedly picked up the lid that was placed aside, and made the lid of the incinerator tight, impermeable to a trace of wind.

All things in the world are all on a circular path, and so is cultivation, and so is alchemy. Lin Chongtian's hands were pressed against the outer wall as they had been at the beginning, and he continued to output his purple fire element power. However, unlike the purple-red light that quickly brightened at the beginning, this time, the purple-red light on Lin Chongtian's hands grew extremely slowly, just like a person who ran with all his strength at the beginning and a person who jogged at the beginning, the gap was very large.

"Son, see clearly, this is the last step - fusion. This step is simple and simple, but difficult to say, first of all, we must use the fire element force to constantly control the pale cyan smoke in the incinerator that is constantly running, compress it, and then compress it until it reaches a critical point, and then control the fire element force to surround the compressed light cyan smoke, just like pinching an object with the palm of your hand. ”

"Finally, slowly increase the fire element power, remember, it can't be fast, it must be slow! When the fire element power grows to a certain amount, the light cyan smoke that is compressed to the extreme, containing rich herb essence, will explode and form a finished medicine pill. If the growth of the fire element power is too fast, and the explosion limit of the pale cyan smoke is suddenly exceeded, then the furnace will be fried! At this point, remove the lid of the furnace and take out the medicine pill, and this alchemy will be over. ”

Lin Yongtai's words revealed an unconcealed excitement, because the first batch of "Tianyuan Dan" related to the future of the family was about to be released!

Not only Lin Yongtai, but now Lin Chongtian's face is flushed, I don't know if it is affected by the temperature or excited. Just as he was slowly increasing his fire power, he had gradually sensed that the pale cyan smoke that had been compressed by him to the extreme was about to reach the temperature of exploding. Although he was only refining a red-grade pill this time, the energy he had expended had even surpassed that of refining a yellow-grade pill, and his seriousness was still too much.

This time, Alchemy Lin Chongtian feels very good, very perfect!

Under the incomparable concentration of his mind, he did not make the slightest mistake, and he was confident that not only the quality of the alchemy this time would definitely be fine, but the quantity of the pill would definitely not be less.

Fortunately, Lin Chongtian didn't know what Lin Nantian, who had watched his alchemy all the time, commented on him at this time, and if he knew, he would definitely vomit blood in anger.

"Well, the patriarch's grandfather has played well in alchemy this time, and there are generally no problems, but many details have not been dealt with well. The most important thing is that the last step is very wrong, how can you increase the fire element power so slowly! That is what a novice alchemist who can't control the fire element power and is not familiar with the raw materials can do this. It should increase the fire element power at the fastest speed to make it explode the pill, so that a part of the herb essence will not be volatilized in the process of increasing the fire element power!"

"It's a pity, this alone is about a waste of three pills. In addition, the patriarch's grandfather doesn't seem to be going back to the pill, so it is estimated that the number of medicinal pills produced is about sixteen to seventeen!" Lin Nantian secretly commented.

"Bang!"

Just when Lin Nantian was secretly pondering, a dull sound sounded in the incinerator, like a thunderclap on the ground, pulling Lin Nantian back from his thoughts.

I saw that Lin Chongtian couldn't wait to open the lid of the incinerator, sucked in his hands, and held all the refined Tian Yuan Dan in his hands, his eyes lit up, his hands trembled slightly, revealing a trace of tenderness and excitement.

"Haha! Good! Very good! Just by looking at this shining star, the dazzling luster, you know that this alchemy is absolutely successful! As long as you wait to see if the medicinal effect is the same as the introduction, you can officially put it up for auction!" Lin Chongtian smiled solemnly, "Let me count how many pills have been fried this time, according to my estimate, it should not be less than fifteen." Yongtai, bring me an empty bottle!"

"Okay, patriarch!" Lin Yongtai danced with his hands, smiled all over his face, took an empty bottle from the shelf next to him and handed it over.

"One, two, three...... Fifteen, sixteen, seventeen!Hahahaha, as I expected! It was really unexpectedly very successful, and I actually blew up seventeen finished pills!" Lin Chongtian smiled happily and was ecstatic, "I have never tried to refine seventeen pills in one furnace! This time, under the pressure of high pressure, I actually performed at a higher level!"

"Congratulations to the patriarch, it's done!" Lin Yongtai looked at Lin Chongtian with convincing feelings.

Only Lin Nantian stared at the raw materials at the bottom of the furnace with stupid eyes that had lost their aura and had lost their luster, and sighed secretly, "Alas, it's wasted, there are still more than half of the herb essence in these raw materials! As long as you use the Hui Dan, you can reuse them and refine double the number of medicinal pills! It's a pity that I can't tell my father and the patriarch the method of Hui Dan now, even if I can't say it clearly, this technique can only be practiced on the spot." Forget it, red-grade medicine pill, these raw materials are not precious, and if they are wasted, they will be wasted!"

Just when everyone was happy that they had successfully refined a high-quality Tianyuan Pill, suddenly, the excited expression on Lin Chongtian's face disappeared, and was replaced by a very solemn expression.
