Yang Ji walked along the cave and soon saw two stone doors.
As soon as he pushed it open, a wave of heat hit him.
The air inside has become distorted under the high temperature, and red heat waves are clearly visible.
This is a sealed stone room, only as big as a house.
The source of the high temperature is the cluster of red flames in the middle of the stone chamber. It is as big as a millstone, rises half a foot high, and is burning blazingly without a trace of black smoke. The flame is very pure.
Yang Ji looked around [the fire in the center of the earth, there is a trace of aura inside.]
There is aura!
Yang Ji's eyes lit up. Although it was not spiritual fire, this trace of aura was much stronger than the flames caused by low-level fire attribute spells.
"In that case, let's start refining."
Yang Ji touched the storage bag, and a palm-sized and simple-looking pill furnace appeared in his hand.
As soon as the spiritual power was input, he quickly became half a foot tall, suddenly landed on the ground fire, and took all of them into the furnace.
【You start refining the elixir, and start warming the furnace.】
Upon seeing this information display, Yang Ji felt excited and instantly felt stable.
Sure enough, refining alchemy is like practicing cultivation, and there is information displayed.
The first step is to warm the furnace. Once the entire furnace has heated up, refining can begin.
Refining alchemy is a job that requires patience. While waiting, Yang Ji took out a thin sheet of elixir recipe and started studying it.
The prescription of this Linghua Pill records the required amount of each elixir, the order in which it is put in, the heat required to refine the elixir, etc.
The elixir can be made into a pill only if the proportion of each elixir is appropriate.
The heat is the key to refining the elixir. It does not work if the firepower is too strong or too low. It must be just right.
Yang Ji studied it for a long time.
A stick of incense also passes quickly.
According to the records on the elixir recipe, after heating the stove with a stick of incense, you can start refining it.
Yang Ji collected the prescription, then patted the furnace lid to reveal a small opening, and quickly put a Linghua grass in.
[There was a sneer, a burnt smell came out, the Linghua grass was ruined, the temperature was too high, and the heater failed.]
Um?
Temperature is too high?
Isn’t it the time of one stick of incense?
Is it because of different flames? The person who wrote this recipe did not use earth fire?
Yang Ji's mind was spinning very quickly, and he immediately thought of this possibility.
At this moment, I am staring into the furnace [the temperature is relatively high, 300℃.]
It seems that 200℃ does not work, so I will try again and find the suitable temperature.
Yang Ji was not discouraged and was ready to try again.
Outside the stone room, I smelled a burnt smell coming from the fire, and I suddenly felt refreshed, thinking:
"I thought you were so capable, but even the heater failed."
"Hehe, I must be following the example of a gourd, how can refining an elixir be so easy?"
"What is described in the prescription is only a rough outline. There are countless small details that are actually put into practice. If there is a slight mistake, the medicine will be ruined."
"You little kid, do you think you can become an alchemist just by recognizing a few elixirs? You still have a lot to learn."
Huo Yuan's little eyes flashed proudly, he clasped his hands behind his back contentedly, and returned to the outside of the cave with a proud expression.
Obviously, he believed that the young man in the stone room was no longer worthy of his continued attention.
In the stone room, Yang Ji continued to try.
[The temperature in the furnace is 250°C, the Linghua grass is destroyed, the heater failed, and the temperature is too high.]
[The temperature in the furnace is 200°C, Linghua grass begins to melt slowly, the furnace is heated successfully, the optimal temperature.]
"It turns out that the optimal furnace temperature for refining Linghua Dan is 200℃. Rather than talking about the furnace, it is better to say that the temperature required to smelt the first Linghua grass is 200℃."
Yang Ji was so happy that he finally took the first step by destroying the two elixirs. He also made preliminary improvements to the elixir in his mind.
Immediately afterwards, he controlled the flame through the secret door at the bottom of the alchemy furnace to keep it at 200°C.
Because [200℃] will be clearly displayed at a glance, so if the temperature is a little higher or a little lower, he can make subtle adjustments to the flame through the secret door in time.
The temperature is constant, and the Linghua grass is slowly melting while ensuring that the medicinal power does not evaporate.
After everything was melted, Yang Ji patted the furnace lid and put in another elixir.
As soon as I put it in, a message appeared instantly: [The green leaf grass is melting at an extremely rapid rate, and 2% of the medicinal power has evaporated.]
Yang Ji took a look and hurriedly lowered the fire. It was not until it stopped at 180°C that the melting of the green leaf grass became stable and gentle.
At this time, Yang Ji improved the recipe and recorded the melting point of Qingyecao.
Linghua Pill is just a low-grade spiritual pill, and it is not that complicated to refine.
There is no need to fuse two or three to form a new liquid.
It is very simple to melt all the elixirs, then perform a fusion reaction according to a specific ratio, and then solidify to separate the elixirs.
Yang Ji smelted two elixirs and finally understood.
At this moment, he looked directly at the remaining five elixirs [Luo Yuncao, melting point 160°C...Liuyunhua, melting point 155°C. Purple Leaf Teng, melting point 100°C.]
Knowing all the melting points, Yang Ji began to melt them one by one.
Finally, I got seven pots of medicine.
Yang Ji began to follow the records on the prescription and left a certain proportion.
But in the end, the seven pools of liquid medicine couldn't be fused together.
Yang Ji was puzzled and looked intently [The ratio of the medicinal liquid is wrong and cannot be fused. The proportion of Luo Yun's herbal medicine liquid is too low.]
He slapped his forehead and suddenly realized.
Yes!
The Luoyuncao recorded in the prescription is fifty years old, but the one I smelted is forty-nine years old.
Although the difference is only one year, the medicinal power contained in them is completely different. If they are combined according to the proportion of the elixir, it will definitely not work.
The fruits on the same tree are sour and sweet, and even the elixirs of the same year contain different potencies due to various reasons such as growth.
No wonder it is said that refining elixir is difficult.
The first difficulty is smelting. If I hadn't had a golden finger to help me, I could tell the temperature in the furnace and the melting point of the elixir at a glance. Otherwise, how could I have been able to control the flame so easily to smelt it?
If there is no golden finger to assist, if the year of smelting the elixir is slightly different from what is recorded on the elixir recipe, then the so-called "percentage of heat" recorded on the elixir recipe will be in vain.
If it is refined according to the heat on the elixir recipe, the firepower will either be too strong or too low, and fine adjustments will be needed during the process.
No wonder it is said that refining the elixir takes three to five days. I think all the time is spent on adjustments.
The second difficulty is the ratio of medicinal liquids.
Although the elixir formula is an empirical ratio obtained through countless elixir refinings, each elixir contains different medicinal powers. If you rigidly follow the instructions on the elixir formula, it will definitely not work.
Similarly, this also requires constant attempts to fine-tune the ratio, which is also a waste of time.
I don’t know how much elixir will be lost during this period.
After Yang Ji refined it for a while, he suddenly became enlightened.
The prescription is just a rough idea, and it seems that the actual operation still needs to be adapted.
At this moment, he was about to smelt some more Luo Yuncao and put it into the alchemy furnace, but at this moment, the information display changed [Because the proportions were wrong, the seven medicinal liquids began to have adverse reactions, the medicinal properties changed, and the medicinal liquid was destroyed
.]
Just hearing a bang, a puff of white smoke rose from the alchemy furnace, and all the medicinal liquid burned instantly.
When Yang Ji saw this scene, he sighed that it was a pity that more than two hundred spiritual stones were destroyed like this.
However, he quickly came to his senses, and after cleaning the alchemy furnace, he started refining it again.
After the first try, the second time was much faster.
After some operation, all seven kinds of elixirs were smelted smoothly in just one stick of incense.
At this moment, he put aside the prescription and looked directly at the medicinal solution [The best fusion ratio is Linghua grass 100%, Luoyun grass 95.2%, Qingyun grass 94.02%... Purple leaf vine 50.01%.]
Seeing this scene, Yang Ji exclaimed in his heart, "Good guy, the 10,000th percentile is accurately determined. If it hadn't been for the action of Zhenjun Nascent Soul, how could he have such a powerful spiritual consciousness to divide the proportions so finely?"
Even if Yang Ji has a golden finger that can see the proportional data in real time, he still has to carefully remove the excess liquid medicine, otherwise how can it be so accurate?
After some operations, he also consumed a lot of energy.
The monster said that refining alchemy requires strong soul perception, and he finally understood.
However, the result was very satisfying to him. The seven medicinal liquids had merged into a new pool of cyan medicinal liquid and started to react.
The next step is to warm it up. When the liquid is thick enough, it can be divided into ten equal parts of the same size.
The last step is to transfer the elixir.
Send spiritual power into the alchemy furnace, causing the divided elixir embryos to slowly rotate along the alchemy furnace, and finally you will get a smooth, round, and good-quality elixir.
Time passed slowly.
After the ten elixirs inside were completely formed, Yang Ji patted the elixir furnace.
boom!
A slight roar spread, and a strong fragrance of red pepper suddenly rose from inside.
The moment he turned on the furnace, the fire source outside the cave pricked up his ears, and suddenly asked in surprise: "This... seems to be the sound of Dan Qi rushing into the furnace?"
Immediately afterwards, a scent of Danxiang rushed into his nostrils, and Huo Yuan's eyes suddenly turned straight.
