The two herbs that had just been exuding a spirit of spiritual energy instantly lost their luster and dimmed, as if they had lost the strength of their whole bodies, and slowly, slowly descended towards the bottom of the incinerator, until they were shrouded in white smoke and could no longer be seen.

"The second step has been completed, the previous process is flawless, and the essence of the main material has been completely refined. Lin Yongtai said.

The purple-cyan light that flickered in Lin Chongtian's right hand was now invisible, replaced by a purple-red light that gradually became brighter. The purple-red light in the right hand gradually became brighter and brighter, brighter and brighter, and in the blink of an eye, it exceeded the brightness of the purple-red light in the left hand. The purple-red light on the left hand seemed to be unwilling to be surpassed, no longer stable at a brightness, and began to gradually brighten. The two rays of light are like two children in a race, neither of them will show weakness, and no one will admit defeat.

"Step 3: The second warm-up, the main purpose is two. On the one hand, the essence on the main material is condensed and gathered to remove impurities, and on the other hand, the melting and fusion speed of the remaining secondary materials is accelerated. Lin Yongtai said with admiration, "It's not a purple-level Yuanshi, the temperature rise is really fast, and the second heating up was completed in less than 20 seconds." ”

Just as Lin Yongtai spoke, the purple-red light of Lin Chongtian's hands had stabilized, and the two rays of light seemed to rush past the child at the terminal at the same time, and the brightness was stable at the same point, and no one was better than the other.

"The requirements for the red-level medicine pill are not too high, and a yuan-level alchemist can often be more than competent. But first of all, his control of the fire element power was not as meticulous as the patriarch, and he did whatever he wanted; secondly, the time it took him to heat up might be dozens of times, or even hundreds of times that of the patriarch. Don't look at your patriarch grandfather who looks very serious now, in fact, he hasn't even taken out Yicheng's strength, and he is very relaxed. Lin Yongtai said with a smile.

Lin Nantian took a closer look into the incinerator, and the white mist that was originally only at the bottom of the furnace had climbed to the center of the furnace, and the color that was not too dense had now turned into a dense white cyan; the only thing that was the same was that the white and cyan smoke was still so restless, still running at high speed in the incinerator, running, as if there was an endless amount of energy. When you get closer, you can vaguely smell a faint medicinal fragrance.

"Look carefully at the actions of the patriarch grandfather, son, you are about to start the most critical step of the entire alchemy-the fourth step. In the entire alchemy process, this step is the most time-consuming and energy-consuming, and the decision not to allow the slightest mistake is not allowed, and the practitioners must not be distracted. One son is wrong, all the plates are lost, it can be said that half of the alchemy is in this step" Lin Yongtai finished speaking, staring intently at the incinerator intently.

I saw Lin Chongtian exhale slowly, his left hand was still firmly attached to the outer wall of the incinerator and continued to output fire yuan force to control the temperature in the furnace, and his right hand kept putting all kinds of herbs into the incinerator like a thousand-armed Guanyin, sometimes putting one raw material in, sometimes two or three raw materials at the same time. Every time he put in the raw materials, the purple-red light on Lin Chongtian's left hand will always change, or brighten or darken, and his right hand is like a magic hand, flashing purple and cyan light for a while, and then flashing lilac light, changing in different colors, so busy!

"The order in which all kinds of raw materials are placed, and when and how to put them? It will be explained in great detail on the prescription, and this is absolutely unmistakable, even if it is 1 second late when the herbs are put in, then the whole furnace of medicinal pills will be scrapped! In this regard, all the alchemists are exactly the same. Therefore, even if it is a red-level alchemist, the red-grade pill he refines will not necessarily be worse than the red-grade pill refined by a yellow-level alchemist, and the most important thing about the difference in level is the pill that can be refined. Lin Yongtai said to Lin Nantian earnestly.

Lin Nantian nodded seriously, indicating that he remembered.

"The raw materials of the wood surname need to be extracted with the wood surname Yuan force, and the speed of extraction is determined according to the proportion of the wood element force of their own physique, of course, if the proportion of wood yuan force in the body is not even 20%, then it is impossible to extract any raw materials of the wood surname. Lin Yongtai continued to guide Lin Nantian's basic alchemy knowledge.

"What is the raw material of the wood surname?"

"You stupid, all the things that grow on the earth are raw materials of the wood family!" Lin Yongtai scolded.

"Shhhhhhhhh Lin Nantian put his index finger to his mouth, "What is the Yuanli surname of the patriarch grandpa's lilac light on his right hand now?"

Lin Yongtai covered his mouth and said softly: "That's the water genus surnamed Yuanli! First, it is used as a raw material for the extraction of the water caste. Lin Yongtai paused, as if he was afraid that his son would ask this stupid question again, and replied: "It is the medicinal herbs that grow in the water, such as jade coral, water horse grass, shark blood flower, and so on. ”

"The second function is to cool down. You see, son, there are not many herbs left next to the patriarch's grandfather, and this crucial fourth step is almost complete. Judging by the patriarch's expression, he should not have made any mistakes. ”

Lin Yongtai seemed to breathe a sigh of relief, "After all, this is just refining a red-grade pill, whether it is the number of raw materials or the extraction of raw materials, it is extremely simple for a yellow-level alchemist, if what is to be refined now is a yellow-grade pill, then the amount of raw materials alone is several times that of the red-grade pill, not to mention the difficulty of extraction." Often, this stage will take 2~3 hours, instead of a few minutes of red-level pills, if you are not careful in these 2~3 hours, then the previous efforts will be wasted.

Lin Nantian watched Lin Chongtian put the last herb beside him into the incinerator , his right hand emitted a light purple light, the solemn expression on his face gradually relaxed, and his movements became more and more skillful. In a few moments, the last herb was also extracted and sank to the bottom of the furnace, disappearing in front of Lin Nantian's eyes. Lin Chongtian let out a sigh of relief, and at this point, the first four steps of alchemy were successfully completed.

Lin Nantian was standing by the incinerator at this time, although there was no wind in the room, but the strong smell of medicine continued to hit his nose. It was a fragrance mixed with the smell of many different herbs, which was very special and soothing, and made people smell it refreshed.

Inside the incinerator, the snow-white smoke had now turned a vivid pale green. The smoke grew thicker, as if it was about to clump. Wandering, spinning, and playing in the incinerator covered the entire incinerator. But the strange thing is that although the incinerator has no lid, the smoke seems to have a spiritual surname, but not a trace of it escapes out of the range of the incinerator.

As if knowing what Lin Nantian was thinking, Lin Yongtai spoke: "These smoke are all the essence of plants and trees extracted just now, and they are free in the entire smoke, and they are all within the control of the patriarch Yuan Li now. Unless the patriarch withdraws the Yuan Force, the smoke will not dissipate. ”;
