The alchemy room is divided into four levels.

The primary alchemy room, with an explosion resistance coefficient of one weight to the Sky Realm, is used by rookies or alchemy apprentices;

The intermediate-level alchemy room, with an anti-explosion coefficient of the second level of the Returning to the Sky Realm, is used by alchemists;

The high-level alchemy room, with an anti-explosion coefficient of the triple return to the Sky Realm, is used by the alchemy master;

There is also a special alchemy room, which is specially used by people with status such as the Great Elder or the head of the family.

After seeing Tang Zixi's ability, Elder Tianshi directly took Tang Zixi to his own special super-grade alchemy room.

"Zixi, I'll start teaching you alchemy now, listen carefully!" Elder Tianshi took out a document and began to explain.

Elder Tianshi took the most ordinary Replenishing Yuan Pill as an example to explain the key points of alchemy.

It turns out that when alchemy, it is not necessary to add all the materials to the tripod at the same time, some materials need to be put in first, and some materials need to be added after a period of time. And the heat is not static, it is adjusted at each stage.

While explaining, Elder Tianshi began to refine the pill and teach by example. Since Tang Zixi had never tried alchemy, Elder Tianshi first asked her to stand aside and watch.

Every detail, every step, Elder Tianshi will explain clearly the purpose and significance of doing so.

I have to say that Elder Tianshi is a good mentor. Not only because of his high level of alchemy and good expression skills, but also because he is willing to teach without reservation.

It took three days for Elder Tianshi to show the whole process of refining a Supplement Yuan Pill in front of Tang Zixi.

"Okay, Zixi, I've taught you all the methods and experience, and now it's your turn to come to alchemy. I'll give you ten materials, six days, and you stay in this alchemy room to give it a try. If I can successfully refine the elixir, I am of course happy, even if you fail, you don't have to be discouraged, no one can succeed in refining the pill for the first time, this time it is just for you to practice your hands!"

"Yes, Master, I will definitely do my best. Tang Zixi said.

After teaching the course for three days in a row, Elder Tianshi was a little tired, and he yawned and left the alchemy room.

Tang Zixi was the only one left in this super-grade alchemy room.

The furnace in the high-grade alchemy room was very large, enough to refine a hundred elixirs at the same time.

Elder Tianshi gave Tang Zixi ten copies of the material, that is to say, if Tang Zixi only refined one grain at a time, he would also have ten chances.

The cycle of refining the Replenishing Yuan Pill was three days, and Elder Tianshi gave Tang Zixi six days, which meant that if everything went well, he could only refine two batches of the Spirit Pill at most.

In order to save materials and leave himself one more chance to practice his mobile phone, Tang Zixi decided to take a copy of the materials to try first.

Tang Zixi put the first ingredient into the furnace and began to control the fire according to the experience taught by Elder Tianshi.

This was the first time she had taken control of the spiritual fire inside the furnace, and she had discovered a strange phenomenon, because her spiritual sense could be combined with the spiritual fire, so her inspiration could reach into the furnace and see the materials inside surrounded by raging fire.

She could clearly see that the materials were slowly dissolved into a liquid by the furnace fire, and they interacted with each other, resulting in another liquid state that was constantly being concentrated and refined. The final stage of alchemy is to cool and solidify the refined stock solution into a pill shape.

Every step, Tang Zixi strictly followed the steps taught by Elder Tianshi, and the materials in the furnace had been fine, but after half a day, they suddenly scorched.

Tang Zixi was not discouraged, she was thinking, maybe there were some details of a certain step that she didn't pay attention to, so it failed.

Tang Zixi cleaned up the slag, put the second material in, and made persistent efforts. This time, she was more careful to follow Elder Tianshi's words. However, she still failed, and it ended in failure after only half an hour of refining.

She watched as the materials scorched. This time, she was sure that she had made no mistakes.

If there is no mistake, why is it still failing?

Tang Zixi was unwilling, she decided to find out the reason. She put a third copy in.

This time, Tang Zixi didn't strictly follow Elder Tianshi's experience. She is based on the experience of Elder Tianshi, and the phenomena seen by the eyes are the secondary. If according to the experience of Elder Tianshi's alchemy, when she found that the material had a precursor of burning, Tang Zixi would immediately weaken the fire, and if she saw that the material lacked heat, she would increase the fire. In other words, the basis of her method taught by Elder Tianshi was fine-tuned according to the actual situation.

Three days later, Tang Zixi finally succeeded in refining the first elixir!

At the moment when the lid was opened, I saw that in the alchemy furnace with curling smoke, there was a pitch-black and round, shiny and black Replenishing Yuan Pill lying quietly. A strong scent of danxiang greeted the face, which made people feel refreshed and relaxed.

Put this tonic pill in the palm of your hand, and a sense of joy of success arises spontaneously. How much she wanted to go to her little husband immediately and tell him that she had succeeded! From now on, she would be able to refine the pill......

But not yet!

This is just a grain of refining! I am too happy, if my own technology can achieve stable mass production, then it is called learning to be successful!

The success of this elixir tells Tang Zixi an experience, that is, experience can only be used to guide practice, so as to avoid detours, but practice cannot copy experience, because in the process of practice, the problems you encounter are ever-changing, if you don't know how to adapt and use the same method to solve problems, then you will naturally fail.

Elder Tianshi's experience was not wrong.

The first and second materials fail because each one is in a different state.

The same alchemy material, harvested in different years and seasons, will have some differences in the content, moisture and properties of its various active ingredients. For example, if the moisture of the spirit grass harvested this time is high, then you have to use a larger fire to bake away its water vapor, if the fire power is low, then the alchemy essence will not be hot enough. If the moisture of the spirit grass is low and it is refined with too much fire, then the original liquid will be easy to coake.

Elder Tianshi's spiritual sense could not penetrate the alchemy furnace to observe every instantaneous change in the material, so the experience he summed up was a method with a high probability of success. In other words, even an alchemy master could not achieve a 100% success rate.

Tang Zixi is different, she can clearly observe the changes in the materials in the furnace and adjust the heat in time, so as to improve the success rate.

After discovering his ability to be different from ordinary people, Tang Zixi was ecstatic.

Now, she has seven materials left.

She couldn't wait to refine one material at a time, she threw all seven materials into the alchemy furnace at once and began refining!

Time passed quickly, Tang Zixi stayed in the alchemy room for another three days, she focused all her energy on alchemy, when she was hungry, she took out some food prepared in advance from the space ring, and drank some water when she was thirsty. These foods were originally prepared for taking Yunhe to the Shenshu Space for recuperation, but I didn't expect that they would not be needed at that time, but instead became the working meal of alchemy now.

After three days and three nights, the second round of alchemy was finally completed! When Tang Zixi opened the lid of the furnace, she saw seven round elixirs lying at the bottom of the furnace. The seven elixirs were rounder and brighter than the first elixir she had refined, and they also exuded a halo of colorful pills. Obviously, these seven elixirs were of a higher grade than the first one.

Tang Zixi knew that this time she had really finally succeeded, and she had completely learned the essentials of alchemy.

Tang Zixi laughed, put away all the elixirs, and opened the door happily, she couldn't wait to run to Lihe Garden to find Yunhe, she wanted to tell him this great news!

The moment she opened the door, she realized that Elder Tianshi was already standing outside the door looking at her with a smile.

"Zixi, I've been waiting for you outside the door since yesterday. Seeing that you have been in retreat, I don't dare to disturb you suddenly!Hearing you smile so happily, do you have some understanding of alchemy?" Elder Tianshi asked kindly.

He didn't hope that Tang Zixi would succeed in alchemy for the first time, as long as Tang Zixi understood something a little and had a deeper understanding of alchemy, he would already benefit a lot.

Tang Zixi happily conjured the first Replenishing Yuan Pill, held it in his palm, and said to Elder Tianshi: "Master, I succeeded, take a look!"

The moment Elder Tianshi's eyes saw that Replenishing Yuan Pill, his eyes were so shocked that they were about to fall out!

How is this possible? The first time you learn alchemy, you can refine it successfully?

"Zixi, ...... you" Elder Tianshi's face turned red, and he couldn't speak for a while.

"Master, what's wrong? Could it be that the level of the elixir I refined is too poor and disappointed you?" Tang Zixi said stunned.

Because Elder Tianshi's expression was so strange, he wanted to laugh and cry, but he couldn't laugh or cry, and his face turned red.

"No!" A few seconds later, Elder Tianshi, whose reflection arc was too long, laughed and said, "Zixi, you are really a genius! I succeeded in the first alchemy, much more powerful than when I was a teacher, I was moved to be a teacher, I can accept you as an apprentice with outstanding talent, I have no regrets in this life, I can finally pass on the alchemy technique......"

As he spoke, Elder Tianshi was so excited that he cried, he wiped his tears and said, "The first time you refine the pill, ten parts of the elixir can refine one elixir, which is the probability of one-tenth of the success, which is already very good! As long as you step up your practice in the future, you will soon master the doorway, and the success rate will be higher and higher." ”

It turned out that Elder Tianshi was not angry, but was moved by Tang Zixi!

"Master, I will definitely work harder in the future. Tang Zixi smiled: "By the way, Master, what level is this elixir?"

Elder Tianshi said: "It is round, the surface is flawless, and there is a strong Dan fragrance, this is a second-grade elixir, which is equivalent to the level of an alchemist." But you are still a long way from a real alchemist, because in the alchemy qualification assessment, in addition to the strict requirements for the level of the elixir, there are also requirements for the success rate of alchemy. At least 80% of the success rate, and at least one of them is a second-grade elixir, and only those who meet these two conditions can be considered qualified alchemists. ”

"And so on, a first-grade elixir, with a success rate of 90 percent, is an alchemy master. Elder Tianshi added: "The threshold for an alchemy apprentice is relatively low, as long as the three-grade elixir is a sixty percent success rate. ”
