"The sub-materials of the Qingyu Spirit Pill, three fresh grasses, big mugwort beans, cooked treasure roots, tiger striped ginger, Youquan Qingshui, fire spirit core, water spirit core, wood spirit core, all brought here~" Tianxun ran back from the hall, and there was a small box in his hand, which was full of the side materials of the green jade spirit pill. The Qingyu Lingdan, which is considered to be a less difficult existence among the two alchemy pills, because the medicinal materials are gentle and mild, and there will be no fierce melting reaction when refining, Tianxun originally planned to make his own prescription, but since Yu Yijie said it, refining a second-refining Qingyu Pill can be regarded as the minimum requirement for the assessment.

"Okay, it's worthy of Senior Sister Tianxun~" Yu Yijie patted his ass and said, Tianxun smiled slightly, it seemed to be quite useful. So, without further ado, Yu Yijie began to prepare for quenching... Wait, quenching?

"You've finished picking?" Tianxun saw that the pieces of perfectly separated green jade flesh petals on the silk cloth on the table were lying quietly, still full of life, and there were quite a few pieces, which showed that the results of the petals were perfect, but in such a short time after she entered the inner hall... Tianxun seemed to see the speed of Master Tianheng's demonstration back then, and it was also completed during the period when she went to the toilet.

What is the implication of this?

Tianxun didn't dare to think about it, so let's focus on the quenching situation here first, and came back to his senses to look at Yu Yijie, at this time he was checking the alchemy furnace and the fire ding, and it seemed that he was ready to start alchemy, etc... Alchemy?!

"What about quenching medicine?" As soon as Tianxun asked, he found several medicinal materials, including Qingyu cultivation, all of which had been quenched and floated beside Yu Yijie. Tianxun was speechless for a while, it was really a moment, there was no extra movement, indicating that the refining technique was exquisite, could it be that this guy was a medicine body ghost who was delayed by the martial arts talisman?

The principle of general quenching is to use spiritual fire to refine the essence of medicinal materials, eliminate superfluous substances, and improve the success rate of alchemy.

Yu Yijie can't do quenching, can only quench the medicine, the essence of the medicinal materials after the quenching is still rich in aura and vitality, but the form is not like the past, it may turn into a liquid, or there may be some structure left, and some essence is left in the green jade plant, which is kept in a small jade bottle, which is not easy to volatile, this process is called quenching, not extraction, because it has been through spiritual fire, so it is called quenching.

Yu Yijie put the small Dan furnace in the fire tripod, threw the three spirit cores into the fire tripod, and urged the spiritual fire, that is, the aura of the fire attribute, and the three spirit cores were gradually burned to ashes, but all the aura in it was integrated into the spiritual fire, and it became the standard three-genus flame for refining the green jade spirit pill.

At this step, there was no problem, so Yu Yijie immediately used the aura to put the essence in the air in the spiritual fire, and the essence of the green jade cultivation could not escape under the high-temperature spiritual fire, and was fixed and refined, and it could not even evaporate, because the spiritual fire was different from other flames, it was a flame directly controlled by Yu Yijie, so it was absolutely not allowed to have any excess loss of the essence in the refining process.

Under the control of Yu Yijie, the flames of the three attributes were processed at different temperatures and with different properties, which made the essence medicine undergo unique changes, and finally reached the level of adapting to the melting pill, Yu Yijie's expression also began to be solemn. The materials are quickly fed into the furnace, and together with the three flames, all of them are included in it, creating a high-pressure melting environment in the Dan furnace, which is the best place to melt the medicine and condense the Dan.

The alchemy furnace given by Tianxun, the three-legged three-mouth open flame furnace, is not a furnace for novices at all, and it is necessary to accurately control the pressure in the furnace to melt each kind of essence that has been quenched to the best state, the more fires the more advantageous, but the more difficult it is to control, the pressure is too small, and the fusion of the essence cannot be melted, not to mention the condensation, the pressure is too high, either the fire is vented, or the furnace is fried, which is a very dangerous thing.

There are two kinds of Dan furnaces, the open flame type and the fire permeable type, the open flame type pays more attention to the quality of the flame and is a direct fire alchemy, while the fire permeable type only focuses on fire, like cooking things. Open flame is a compulsory technique in the later stage, and fire penetration is only a substitute for practice, because of the lack of flame blessing, the limit of Danpin cannot reach the open flame type.

Yu Yijie controlled the three open flame furnaces, and he was already barely concentrating all his mental power to sense the situation in the furnace, almost forgetting his breathing, not seeing or hearing, and paying full attention to the aura induction, every change in pressure and the movement of the flames were all in his control.

Tianxun is well aware of the difficulties in this link now, so he can only help each other, after all, Yu Yijie has not undergone the special training of anti-pressure alchemy, and now he must be given a quiet environment, his surroundings have been covered by Tianxun's aura, and Yu Yijie can't feel any movement outside the aura inside.

The fusion of essence medicine is a long and boring process, which determines the degree of retention of medicinal power after condensing pills, which is an important step in determining the pills. Even if it is a green jade elixir, it is much more difficult than what he usually practices, and it is not 100% possible to refine it if he wants to release the pill, Yu Yijie is experiencing the cultivation of spiritual power for the first time in his life at the moment, which is much more unbearable than spiritual energy.

Tianxun looked at it, as if he saw the land of the year, and himself, under the guidance of Master Tianheng, the first alchemy, however, Yu Yijie did a better job than both of them, if it succeeded...

"Ning Dan!" Yu Yijie After a few hours of melting pills, he finally fused all the essence medicine perfectly, and officially ushered in the time of Ning Dan. Use the aura as the unformed Rong Dan solid type, completely control the fire and pressure, and the three fire ports suddenly burst into flames, which is a normal phenomenon of Ning Dan, but the fryer is not, so Ning Dan Jiagong must accurately grasp the limit of the alchemy furnace, sometimes the Dan furnace can not cope with the needs of the Ning Dan, so it can only be made up for with time, but it will still lose some medicinal power and quality.

This three-mouth furnace is at ease, refining the elixir of the Qingyu Spirit Pill, there is no need to worry about the fryer at all, because even if it fails, its medicinal properties will only make it burn to ashes, and it will not be fried at all. The process of condensing Dan is slightly easier than that of Rongdan, as long as you maintain the Dan type and maintain the environment that should exist in the furnace, Ningdan is a simple thing and does not need to spend too much mental power.

After a while, the amount of fire discharged from the fire mouth became less and less, this is one of the phenomena of Ning Dan's close success, after all, fire is also an important part of the pill, and the three spiritual qi are all absorbed into the pill through the fire effect, and if it is Shi Dan, it will condense into a Dan pattern. As the spiritual fire gradually decreased, the furnace pressure decreased, and the Dan furnace no longer vented the fire, and the last trace of fire left was collected into a special fire charm and used to wrap the refined elixir, so that it could be perfectly preserved.

Ning Dan succeeded, Yu Yijie finally opened his eyes, handsomely waved his hand, the top of the furnace was suddenly flew, a cyan aura of the pill flew out of the medicine mouth, after a few circles in the air, slowly fell into Yu Yijie's hands, Yu Yijie was slightly panting at the moment, sweating profusely, his clothes were soaked, but the hard work paid off, the green jade elixir was successfully refined, Yu Yijie handed over the pill to Tianxun on the spot, he didn't have to look at it, he was full of confidence.

Tianxun took the pill, took it in his hand and weighed it, the weight was quite sufficient, the two Dan lines jumped on the surface, the aura gathered the Dan, and the refracted light was like a cloud, which was the perfect quality of Shi Dan. The collection of medicines, quenching medicines, and refining medicines were all successful, and Tianxun was also relieved, he really didn't see the wrong person.

"Second refining of the green jade pill, the best of the pill, the texture is clear, the aura is sufficient, the medicinal power is visible, do you plan to take it, or give it to me as a souvenir?" Tianxun poked his head over and asked, Yu Yijie didn't think about how to answer, only to see that the Qingyu Lingdan, which had been hidden by Tianxun and disappeared, and she was staring at herself, as if she didn't plan to return it.

"So... Give it to my senior sister as a souvenir..."Yu Yijie was embarrassed to take it again, so he could only obediently hand over the tinder talisman, and Tianxun happily took out the pill and wrapped it in the tinder talisman. It stands to reason that she can refine these two alchemy pills casually, what is so rare?

"Senior sister, my medicine spirit practitioner assessment..."Yu Yijie asked tentatively.

"It's over~ It's all over, you can go back after cleaning up, and I'll come back next time~" Tianxun immediately returned to the inner hall like a baby, and didn't care about Yu Yijie, then it seems that she saw it, Yu Yijie used his own blood on this Qingyu Pill, which is one of the essences of the medicine spirit, since it has passed, it means that the blood is effective~

Yu Yijie also cleaned up and walked out of the lobby, and when he saw that it was already dark, only Qianxun and Wu Jun'er were still guarding not far from the door, and when he saw Yu Yijie coming, he immediately stood up and walked to Yu Yijie's side.

"It's a lot of sweat... Isn't it difficult?" Chihiro saw that Yu Yijie's clothes were soaked, as if he had experienced a hard battle, and he didn't know if he had passed...

"Look at the expression, and you know it's passed. Wu Jun'er turned his head and said to Fan Qianxun, Yu Yijie's face was relaxed and happy, it was indeed not like the expression of not passing, Yu Yijie also admitted the facts, the two were overjoyed, and they informed everyone of their current location, or in the pavilion in the outer courtyard.

Today's mental and physical strength are seriously consumed, Yu Yijie felt that after relaxing, he was hungry and sleepy, and it happened that everyone hadn't eaten yet, so the three of them went to the canteen to buy a lot of things at once.

In the face of Yu Yijie's gobbling, everyone was a little surprised, but considering the test questions of the medicine body, everyone couldn't imagine what Yu Yijie had experienced for most of the day, and when he filled his stomach a little, he had time to share what he had just done with everyone while eating.

After Yu Yijie finished speaking, everyone had more expressions of disbelief, this guy's mastery speed and ability to use skills are too incomprehensible, the original assessment of the medicine body is one that everyone is not optimistic about, Yu Yijie has not only cultivated the martial arts to a high level in more than two months of cultivation, but also mastered more spells, and even the medicine body has become omnipotent...

"You're probably the true cultivator..."Lin Qingyuan also scratched his head and said haha, the difference between the Dao levels has no comparative value, this guy's cultivation mastery and skills can be their little master, the so-called people on the earth, there are heavens outside the sky, that's probably what happened.

"Don't you have a lot of skills, besides, this is not the assessment requirement? Yu Yijie was busy eating, and he didn't pay much attention to everyone's eyes.

"But the time is too short, right?" Yuan Liang, as the representative who could not learn the most, couldn't help but complain.

"That's because I've got the idea, I'll tell you about it later, and I'll wait until I'm full!" After speaking, Yu Yijie gobbled it up again, and after five minutes, he was considered to have filled his stomach.

"Don't mind if I take off my shirt, do you?" Yu Yijie didn't wait for everyone to answer, he directly took off his sticky shirt, put it aside, and then began to share the tricks of mastering the exercises.
