Qin Yu slowly restrained his excitement, and then began to sit quietly, waiting for his mood to calm down. Alchemy requires calmness, and his current state is obviously not suitable.

Slowly, Qin Yu opened his eyes again. At this time, Qin Yu was not shocked, and his face was serious.

"Tianmen, gossip, positive. The flame in the gossip furnace burned again.

Subsequently, Qin Yu quickly threw a blue spirit flower into the gossip furnace. Then control the temperature of the flame to reduce the blue spirit flower and purify it. Slowly, the blue spirit flower turned into a cloud of medicinal liquid. Immediately afterwards, Qin Yu put another green silk grass into the gossip furnace, and under Qin Yu's patient refining, the green silk grass was also transformed into a medicinal liquid.

In the end, Qin Yu put the two black flavor fruits into the Bagua Furnace and slowly refined them into medicinal liquid.

Finally, Qin Yu turned all the three herbs into a medicinal liquid. However, this is not the end, and at the most critical juncture, it is Hedan. If this step is not done well, then this alchemy will be wasted.

Under Qin Yu's control, the three clusters of medicinal liquid slowly approached.

However, the three close masses of liquid showed no signs of fusion. Qin Yu was secretly anxious at the moment, and at the same time worked harder to force the three groups of medicinal liquid to fuse.

Suddenly, with a "bang~", there was a violent explosion in the gossip furnace. Fortunately, the quality of the gossip furnace left by Lei Wei was excellent, and the explosion produced by the three medicinal liquids was not strong, so it was not a big problem.

However, correspondingly, Qin Yu's first alchemy failed.

"Why is this happening, why can't the liquid medicine fuse?" Qin Yu thought to himself.

After that, Qin Yu started to try again. However, just like the first time, the three liquids could not be fused, and eventually an explosion occurred.

After trying many times in succession, all of them had the same result, and Qin Yu's mood also became irritable.

"How can this be? This is the most ordinary second-grade Qi Benefiting Pill, do I really have no alchemy talent?" Qin Yu couldn't help but become frustrated.

At this moment, a hawk chirped. Qin Yu raised his head and saw Xiao Hei's eyes full of doubt.

Qin Yu had been concentrating on alchemy before, and he hadn't paid attention to Xiao Hei, but seeing Xiao Hei at this moment, Qin Yu suddenly became happy.

"Hey, I don't want to, let's relax and relax. Qin Yu muttered to himself. Then he said to Xiao Hei, "Xiao Hei, let's go, let's make snake soup to eat." ”

Xiao Hei immediately chirped excitedly, Qin Yu had made snake soup once before the Heavenly Tribulation, and then Xiao Hei liked the taste. So as soon as Qin Yu said that he wanted to make snake soup, Xiao Hei became excited.

The kitchen of Lei Shanju is very advanced and has all kinds of utensils. And it's mostly automated. Qin Yu basically doesn't need to do it himself, he only needs to press a few buttons, and it's all right. And there is also a timer function, as long as the time is set in advance, it will automatically cease fire and clean up everything. In short, in the middle of Thunder Mountain, enjoying the food is just a little casual.

Of course, all kinds of ingredients still need to be prepared by Qin Yu. After all, no matter how high the technology of the kitchen is, it is difficult for a clever woman to cook without rice.

Xiao Hei chopped and ate the snake soup on his plate, while chirping a few times from time to time. Qin Yu also tasted the delicious food while smiling and looking at Xiao Hei who kept tweeting.

After enjoying it, it's time to go to cultivation. Qin Yu didn't go out into the alchemy room this time. Because Qin Yu hadn't thought of how to solve the problem of fusing the liquid medicine. So Qin Yu walked straight to the practice room.

Qin Yu planned to cultivate here for a year and then go back, after all, there was nothing to do when he went back now, the same was cultivation, wouldn't it be the same everywhere? But one year was the longest Qin Yu could stay here. A year later, Qin Yu would be eighteen years old, and Qin De's Heavenly Tribulation in the original book was when Qin Yu was eighteen years old. He had to go back to protect his father. However, there is another problem with Xiao Hei's catastrophe. If Xiao Hei didn't survive the Heavenly Tribulation and didn't reach the Jindan stage by then, then his plan would have been aborted.

And Qin Yu knew from Xiao Hei that Xiao Hei's Heavenly Tribulation would descend in three months. In this way, you can smoothly shuttle through the flood wilderness and return to the Qianlong Continent.

…………

In the practice room, Qin Yu first began to practice attack skills. There are some attack techniques in "Star Change" that Qin Yu can cultivate now.

Qin Yu used strenuous exercise and strong training to vent the dissatisfaction in his heart, and finally vented all his frustration.

In this way, Qin Yu, who was in a good mood, began to cultivate.

Qin Yu, who sat down, probed his consciousness into his body and began to work hard to run the star change.

Suddenly, Qin Yu opened his eyes suddenly, and then rushed out of the practice room and came to the alchemy room.

Qin Yupan sat in the Bagua Furnace Flash, and the herb for refining the Second Grade Qi Benefiting Pill was next to him.

Qin Yu didn't start alchemy immediately. He knew that it was easy to make mistakes in alchemy like this, and the success rate was not high. So Qin Yu began to sit quietly to calm down.

After a long time, Qin Yu finally opened his eyes.

The stars are really on fire, "Tianmen, gossip, positive." ”

The gossip furnace lit up again. Immediately, Qin Yu skillfully refined the three herbs into a medicinal liquid. He's done it many times.

Finally, it's time for the last step - Hedan!

Qin Yu carefully controlled the three medicinal liquids to approach, and then, Qin Yu did not force them to fuse. Instead, start to get them spinning. It's like a whirlpool.

Under Qin Yu's control, the three medicinal liquids slowly rotated, and then slowly accelerated. And as the three medicinal liquids swirled, they finally fused together a little bit. Immediately after that, there are more and more parts that are integrated. In the end, the three liquids finally fused together.

The liquid medicine that fused together was divided into ten equal parts by Qin Yu, and then the temperature slowly dropped, and the liquid medicine also slowly solidified, and finally formed a pill - Erpin Yiqi Pill.

"Hahahaha. Qin Yu laughed excitedly. provoked Xiao Hei, who had just come back from foraging, to be puzzled.

"I was blamed before, I was too stupid, where was there brute force to fuse the liquid medicine. That's stupid. You still need to think about what you do. Wisdom is the key to the success of things, and you can't just use brute force. Well, never do such a stupid thing again. It's enough for a fool to do it once. Qin Yu muttered to himself excitedly.

However, Qin Yu didn't know that the method of using rotation to accelerate the fusion of medicinal liquids like him did not exist in the current cultivation realm. In today's cultivation realm, alchemists only let the medicinal liquid fuse on its own, or use some special techniques to guide the fusion, but there is no one like Qin Yu who can control the fusion of the medicinal liquid. The process of waiting for the fusion of the liquid medicine is relatively slow, and even if there is a technique to guide the fusion, it is very laborious. So alchemist is a profession that tests patience.

However, the alchemy books that Qin Yu saw only introduced the last step of alchemy to be combined, but did not explain how to combine the pills. After all, ordinary people just go with the flow, where is there anyone like Qin Yu who forcibly combines Dan. So under all kinds of coincidences, Qin Yu created a method of rapid Hedan, that is, the rotation of the Hedan method.

Moreover, this rotation of the Hedan method not only speeds up the speed of the Hedan, but also improves the degree of the Hedan.

In general, in the process of self-fusion of the liquid medicine, there are always some reasons why the liquid medicine cannot be completely fused, and the most is fused eighty percent. So there's always a part of the liquid that goes to waste.

The so-called difficulty of Hedan, the most important thing is the difficulty of eliminating the liquid medicine that has not been fused. In this way, in the final condensation process, there are always some unfused medicinal liquids mixed with the fused medicinal liquid. As a result, the quality of the elixir decreases.

However, Qin Yu's rotating Hedan method can quickly and completely fuse the liquid medicine, which not only speeds up the speed of the Hedan, but also makes the liquid medicine not waste in the slightest, and at the same time improves the quality of the elixir. This shows how clever Qin Yu's rotating Hedan method is.

Chapter Twenty-Eight: Alchemy

The second-grade Qi Benefiting Pill had been successfully refined, and Qin Yu was really full of joy. However, Qin Yu still didn't know what the quality of the pill was, so he couldn't wait to find someone to test it.

However, Qin Yu is in the wilderness, where are the people, there are many animals. I had no choice but to go to the green fire wolf to test the medicine.

Qin Yu walked out of the alchemy room and saw Xiao Hei looking at him with a puzzled expression.

Originally, Qin Yu planned to let Xiao Hei try this second-grade Qi Benefiting Pill, but Xiao Hei was now already a congenital Great Perfection, and the second-grade Qi Benefiting Pill was useless to him. The quality of the natural second-grade Yiqi Pill can not be tried.

Qin Yu smiled and touched Xiao Hei's head, "Xiao Hei, follow me." Then Qin Yu and Xiao Hei came to the Thunder Mountain Residence.

Qin Yu was waiting for the arrival of the green fire-headed wolf. He had just sent a soul message and notified the blue-headed wolf to come to him.

A moment later, a cyan giant wolf that was a few points bigger than a tiger ran towards Qin Yu. With this expression of a green-headed wolf, Qin Yu named it Xiaoqing.

When Xiao Hei saw the green fire wolf running over, he immediately rushed forward to kill it. In Xiao Hei's opinion, this is his territory, and this green fire wolf dares to come to his territory, purely to seek death.

Looking at Xiao Hei who was about to rush out, Qin Yu hurriedly stopped him. "Blackie, don't be impulsive, I let this wolf come. ”

Xiao Hei chirped a few times, obviously puzzled. Qin Yu smiled and didn't explain much.

Xiaoqing walked to Qin Yu, and then squatted on the ground, wagging his tail, looking at Qin Yu with a flattering look in his eyes. It looked like a dog.

Qin Yu smiled and touched Xiaoqing. Then he took out a second-grade Qi Benefiting Pill and threw it casually.

Xiaoqing immediately jumped up and swallowed the pill in his mouth neatly. Then he crouched there motionless.

Qin Yu's soul spirit probed into Xiao Qing's body, carefully paying attention to the changes in Xiao Qing's body. And Xiao Hei watched all this curiously.

The Second Grade Yiqi Pill melts in the mouth, instantly generating streams of pure energy in Xiaoqing's body. These energies are very gentle, and they are slowly assimilated by the energy in Xiaoqing's body and become their own energy. At the same time, Xiaoqing's strength has also improved a little. It's not much, but it's obvious.

However, the pill in Xiaoqing's body was not completely turned into energy, in addition to most of the pure energy, there was also a part of the residue in Xiaoqing's body, which became an impurity in Xiaoqing's body. Moreover, these residues enter the meridians along with the energy, and there is no way to get rid of them except for special methods, such as thunder and lightning refining and improving the quality of true qi.

If Xiao Qing takes too much Erpin Yiqi Pill, the more residue will be produced in his body. At the same time, due to the residue, Xiaoqing will form a kind of resistance to the Erpin Yiqi Pill, and the effect of taking the Erpin Yiqi Pill will become less and less obvious. And it will also bring a lot of trouble to cultivation.

Of course, there are generally residues in the elixir. There has never been an elixir without residue in the cultivation realm. Moreover, the residue contained in the elixir was much more than Qin Yu's elixir.

The residue in the pill is mainly produced in three aspects.

On the one hand, due to the slight difference in flame temperature during the purification of the herbs, the impurities in the herbs are not removed cleanly enough, or a part of the essence refining waste is turned into residue. Of course, if this step of fire control is like a finger swing, then there will be almost no residue. Qin Yu naturally did not produce residue at this step.

The second aspect comes from the fact that the part of the medicine solution that was not completed at the time of Hedan was not removed, and at the same time, it was not removed. Qin Yu Alchemy is a complete fusion of medicinal liquids, and naturally there will be no such residues.

The residue of the third aspect still comes from Hedan. In the case of Hedan, perhaps because the proportion of herbs was not precise enough, the two medicinal liquids were fused, but the third medicinal liquid was not fused. The two medicinal liquids fused together cannot form an elixir, but they are regarded as the fused medicinal liquid by the people of Hedan, and it will also form residues in the human body.

The residue in Qin Yu's elixir is this third type of residue. In other words, the responsibility of the second grade Yiqi Pill is not perfect and accurate enough.

"It seems that the effect of this second-grade Qi Pills is not bad. It's just that there are still some flaws, and they still need to be improved. Qin Yu nodded with satisfaction.

Xiao Qing, who opened his eyes, immediately wagged his tail again, and looked at Qin Yu expectantly.

"You brute, you are insatiably greedy. Qin Yu scolded with a smile.

Then he threw out a second-grade Qi Benefiting Pill and turned around and went back to Lei Shanju.

Xiao Hei was puzzled, why this green fire wolf would listen to the eldest brother, and why the eldest brother was so excited after giving it a small pill.

What Xiao Hei doesn't understand the most is why this green fire wolf just refuses to go. No matter how much Xiao Hei intimidates or beats, the green fire-headed wolf just won't leave. This made Xiao Hei faintly angry. This is his territory, but this green fire wolf is not leaving, how can this not make Xiao Hei angry.

However, Xiao Hei will not kill the green fire wolf. Because he understands that since this green fire wolf was called by his eldest brother, it is his eldest brother's wolf, that is, his own people. Xiao Hei will not be a killer to his own people.

Qin Yu ignored Xiao Hei and Xiao Qing messing around outside, and instead returned to the alchemy room. This time, he was going to improve the Second Grade Yiqi Pill to achieve a more perfect state.

Qin Yu refined the three herbs into a medicinal liquid. Then he began to study, and then he divided each of the three balls of liquid medicine into ten equal parts. Then take one of the Blue Spirit Flower Liquid, one Green Silk Herbal Liquid, and two Black Flavor Fruit Liquid for Hedan.

After fusion by the rotary haltan method, a new liquid medicine is formed. Qin Yu's spiritual sense penetrated into the medicinal liquid and carefully observed. He found that there were some black flavored fruits in the medicinal liquid, and it was obvious that there were too many black flavored fruits. Cooling the liquid medicine aside, Qin Yu then began the experiment again.

This time, Qin Yu divided the remaining medicinal liquids into ten equal parts, one portion of each medicinal liquid. Then take a large part of the blue spirit flower liquid, a large part of the green silk herbal liquid, a large part and nine small parts of the black fruit liquid for Hedan.

After this Hedan, Qin Yu took a closer look and found that there were some newborn medicinal liquids in the medicinal liquid. Qin Yu carefully discerned and found that these medicinal liquids were formed by the fusion of blue spirit flowers and black flavor fruits. In other words, the amount of green silk grass is not enough.

So Qin Yu began to study again, and this time he added a small amount of green silk grass.

In this way, Qin Yu did some cautious research step by step. Of course, research is very draining. If it weren't for the fact that Qin Yu's main soul was already at the peak of the Cave Void Period, and because Qin Yu had two souls, he would not be able to support such a study.

Just like the alchemists in the cultivation realm now, waiting for Hedan is a little lacking, where is there still the strength to study. Even if it is studied, it can only be said that the whole herb is not as accurate as Qin Yu's. Therefore, all the pills in the cultivation realm are whole herbs.

In the end, under Qin Yu's insistence, he finally researched a relatively perfect ratio, one hundred parts of Blue Spirit Flower, one hundred and fourteen parts of Green Silk Grass and one hundred and ninety-three parts of Black Flavor Fruit. The second-grade Yiqi Pill refined in such a ratio has almost no residue. Even if there is, it can be ignored.

Qin Yu finally smiled. Then Qin Yu refined some second-grade Qi Benefiting Pills in such proportions. Although the residue in the pill is equivalent to nothing. However, physical research is still needed. If you don't give the wolf to eat, how do you know what the specific effect is?
