Back in the cave, Su Zimo was not in a hurry to refine the elixir, but continued to digest what he had learned today. If he had any doubts, he secretly wrote them down.
Then Su Zimo memorized the recipe for the Spirit Gathering Pill, and the day passed.
Night falls.
According to the previous plan, Su Zimo should be lying on the stone bed at this time and continue to practice the Secret Code of the Twelve Demon Kings of the Wilderness.
But now, he could no longer practice in the Marrow Cutting Chapter, so Su Zimo had no choice but to fall into a deep sleep according to the breathing and breathing methods in the first three chapters of Body Tempering, Muscle Changing, and Bone Forging.
Fortunately, I have just finished practicing the marrow cutting chapter and have not formed a habit yet.
The next morning, Su Zimo got up early and began to practice the Qi Condensation Art. He took out the spirit stone from his storage bag and held it in his palm, and began to improve his cultivation level.
After the fifth level of Qi Condensation, Su Zimo could clearly feel that his cultivation speed had slowed down.
If he only absorbs the spiritual energy between heaven and earth with the help of spiritual stones, by the end of the year, he may reach the eighth level of Qi Condensation at most.
After all, Su Zimo still allocated most of his time to refining elixirs and learning how to fight with a sword.
In a blink of an eye, it was almost noon.
Su Zimo left the cave again and headed to Danfeng with his sword.
Surprisingly, the one who was preaching and solving doubts at Danfeng today was actually the head of Danfeng, a young man with gray hair and a childish face!
Compared with his previous divination knowledge, the white-haired boy's attainments in alchemy were much higher.
During the explanation, the white-haired boy's eyes would always fall on Su Zimo, intentionally or unintentionally, for some unknown reason.
After listening to it for half an hour, all the doubts in Su Zimo's heart were cleared up, and his understanding of alchemy became much deeper.
After the explanation, Su Zimo was about to leave, but the white-haired boy suddenly stopped him and waved to him.
Su Zimo walked over quickly.
"How is it? Do you understand?" The white-haired boy smiled and had a gentle attitude.
Although the leader of Danfeng looks like a young man, his tone is no different from that of an old man, which shows that this person is now in a state of rejuvenation.
"Yeah, not bad." Su Zimo nodded.
"Any doubts?"
Su Zimo pondered for a while and asked: "I heard Senior Brother Bu say before that there are three parts of poison in medicine. Unless it is a perfect elixir, there will be impurities in even the best elixir. If a monk swallows the elixir, will it Will it affect your practice?"
A flash of admiration flashed in the eyes of the white-haired young man, and he nodded: "In the world of alchemy, the reason why impurities accounting for 40% is called low-grade is because over the long years, this is the experience summed up by countless forefathers of alchemy. What is certain is that as long as it is a high-grade elixir, even a low-grade elixir is harmless to monks."
After a slight pause, the white-haired young man continued: "However, some senior alchemists have also pointed out that taking too many elixirs will cause impurities to precipitate in the body and are difficult to eliminate, which will still have an impact on practice. This is not true in the world of cultivation. One, because no one has discovered the specific impact yet.”
Su Zimo nodded.
The white-haired young man patted Su Zimo on the shoulder and said: "Go back and practice more. Refining elixirs is simpler than refining weapons. Practice makes perfect. If you have the third-level spiritual fire as a foundation, you will definitely be able to do it. If you have any questions in the future, you can come to me at any time. .”
Hearing this, Su Zimo suddenly realized.
The white-haired boy came to give a lecture today, probably because of him.
Su Zimo felt warm in his heart and nodded.
The white-haired boy handed Su Zimo another storage bag and said, "There are a lot of spiritual trees and herbs in it, which are enough for you to make elixirs. Take it."
Su Zimo hesitated a little, took the storage bag, and bowed deeply.
…
Return to the cave.
Su Zimo took out the alchemy furnace and prepared to refine the elixir for the first time.
On the body, the four spiritual materials have been arranged neatly according to categories.
Su Zimo also knew the prescription by heart.
The first step in refining alchemy is the end of material selection.
The second step is refining.
As the name suggests, this step uses spiritual fire to remove impurities from the spiritual wood herbs and extract the essence.
Unlike weapon refining, the higher the level of spiritual fire, the better the refining effect.
Spirit wood herbs are not as hard as spirit minerals, and require constant roasting by fire.
Most of the spirit wood herbs are extremely weak, and their ability to withstand the temperature of the flames varies.
If the temperature is slightly higher, the herbs will turn to ashes on the spot and can only be refined again.
If the temperature is slightly lower, the refining effect will not be achieved.
This requires the alchemist to practice continuously and memorize the flame temperature suitable for the extraction of each spiritual wood herb.
Su Zimo took a deep breath, picked up one of the spiritual herbs, and began to refine it.
"call!"
As soon as the flames rose, the spiritual grass was instantly burned to ashes.
Linghu saw this scene from the side and instantly grinned, his eyes full of amusement.
Su Zimo glanced at the spiritual tiger, with a calm expression, picked up another spiritual grass and continued to try.
Fail, continue!
If you fail again, continue...
Su Zimo's eyes were firm and undeterred, and he kept trying to adjust the temperature of the flame.
Finally, this spiritual grass was burned by the flames and turned into a pinch of powdery essence.
Su Zimo put the powder into a corner of the alchemy furnace and continued to refine the next spiritual grass.
It failed again. After a long time, the second pile of powdered essence was put into the alchemy furnace to distinguish it from the powdered essence of the first strain.
A full two hours had passed, Su Zimo had sweat on his forehead, and his spiritual energy was almost exhausted, before he refined all four spiritual herbs and placed them in the four areas of the alchemy furnace.
Su Zimo breathed a long sigh of relief, sat cross-legged and began to restore his spiritual energy.
After a while, Su Zimo stood up and performed the third step of alchemy, fusion.
In this step, four piles of powder essence must be blended together in a certain proportion and order.
This step is relatively simple, and the proportion and order are clearly recorded on the recipe for the Spirit-Gathering Pill.
However, if the ratio is even slightly different, the quality of the finally condensed elixir will be very different, and the elixir condensation may even fail.
After fusing in one place, proceed to the fourth step of alchemy, the second refining.
This time refining is the most critical.
Once it fails, all previous efforts will be in vain.
The essences of four different spiritual herbs are fused together, and the structure is greatly changed to withstand high temperatures. At this time, it needs to be burned with fierce fire.
The advantages of level three spiritual fire are now revealed.
Whether it can be condensed into elixir in the end and whether it can be refined into a high-grade elixir depends on how many impurities can be removed by burning the essence of the spiritual grass in this step.
The red third-level spiritual fire continued to roast the alchemy furnace, and the powdery essence inside gradually turned into a liquid state.
The nine small holes in the alchemy furnace began to overflow with white gas, and a faint medicinal fragrance came out.
If the level of the spiritual fire in this step is too low, black mist is likely to drift out. Not only will there be no medicinal fragrance, but some pungent odor will be emitted.
After half a ring, the second refining is over.
The fifth step in alchemy is condensing the elixir.
There is no room for any distraction in this step, or even a little influence from the outside world, otherwise the pill condensation will definitely fail!
Su Zimo took a deep breath, kept his mind calm, and began to divide the essence liquid in the alchemy furnace into nine parts, condense them together, and gradually take shape, transforming into a solid elixir.
At this moment, a sudden change occurred!
