The same cave, cold and dark, covered with blood. The only difference is that the pool of blood in the center of this cave is missing. And Qiao Yu sat quietly on the cold ground, looking at the pile of heavenly treasures in front of him with his arms crossed, his face thoughtful.

Here, this is Qiao Yu's dream, everything is an illusion condensed by his method of controlling dreams. However, after careful calculation and setting, all the phenomena that exist at present are almost indistinguishable from reality. And what he had to do was to practice and familiarize himself with the first step of refining the Drunken Immortal Drink in this dream realm.

The whole process of refining the Drunken Immortal Drink is deceptively simple. However, for Qiao Yu, who had only cultivated to the Qi refining period, it was actually quite troublesome. It takes a lot of time just to refine the treasures of heaven and earth, not to mention that there are still remaining steps, which are complicated and troublesome. It was a challenge to successfully refine three barrels in one month.

First of all, the first step is to refine the koji. In terms of Qiao Yu's current spiritual power, if only one wine material is quenched at a time, it will take seven days to complete the quenching of the material alone. Fermenting koji, on the other hand, also takes a day.

Eight days is not a long time compared to a month. But the next step is far more complex than the first step. After Qiao Yu's careful consideration, he finally summed up one point. That's the first step, and it has to be done in at least two days.

Shortening the time from eight days to two days is naturally extremely difficult. However, for Qiao Yu, who has the ability to control dreams, it is not unrealizable. It takes time, a lot of trying, and learning from experience, all of which can be accomplished in dreams.

After entering the dream control, the flow of thoughts increases rapidly like a rapids in an instant. All this thinking, for Qiao Yu, is just a momentary effort. The next moment, he immediately began to prepare and began to practice the tempering steps.

The copper tripod was stimulated, and the moment the copper net appeared, Qiao Yu was so fierce that he reached out, picked up a piece of wine, and threw it into the tripod. The flame technique operated, and a flame flew out from his palm, rushed into the ding, and in a blink of an eye, it burned and occupied most of the part.

Simply try to keep the flame to a certain level so that the fire is not too powerful and the material is damaged. Or the fire is too small, and the quenching process is too slow. Qiao Yu tried repeatedly for nearly ten or so times before he finally found his feeling and successfully mastered it.

The process of quenching the material is extremely boring and bland. The control and use of flames are also constantly consuming spiritual power.

An hour passed in the blink of an eye. When the first wine material was successfully quenched into a liquid form, Qiao Yu hurriedly took it out with a jade piece wine vessel, stored it in the pot, and started the quenching of the second wine material again.

In the same hour, Qiao Yu successfully refined the second wine material in the same way. The continuous tempering for two hours finally completely drained Qiao Yu's own spiritual power.

Then, it is to operate the spiritual power, restore the pranayama, and replenish all the lost spiritual power. This process, based on Qiao Yu's cultivation of the Meditation Determination, also takes an hour to restore his majestic spiritual power.

In three hours, refine two liquor ingredients and restore all the depleted spiritual power. At this rate, a day without sleep can only be tempered six wines. And to complete the twenty-five realms, it will take more than four days. In addition to the fermentation time, it takes five days, which is only three days shorter than eight days, and it does not meet the expected two-day requirement at all.

In this state, 25 sake ingredients were successfully refined and fermented, and it was finally found that it took five days. However, there is a huge difference between the dream and the real time. According to Qiao Yu's current dream control ability, in reality at this time, about ten hours have passed, nearly a day.

There are twenty-nine days left until the month of January. However, Qiao Yu still couldn't live up to expectations. Immediately, after thinking about it, I skimmed the previous method and began to try a new method.

This time, he chose to quench three materials at the same time. This has a new change in the control of heat. However, after several attempts, he quickly succeeded in mastering it. However, what he didn't expect was that in the process of refining his efforts, the speed was raised, but the consumption of spiritual power became a fatal problem.

Quenching three materials at the same time requires far more firepower than quenching one. Every time Qiao Yu was refining, he was about to succeed, because his spiritual power was exhausted, and only one of the three materials was successfully refined. In a good case, there will be two successes, but the chances are not high. But no matter what, it is impossible to complete the three realms at the same time.

After repeated attempts, learning from various failed experiences, and thinking. In the end, Qiao Yu finally summed up the root cause of the problem and found a way to solve it.

His own problem is that in order to force the speed of improvement, it leads to a lack of spiritual power and fails. To solve this problem, it is necessary to reconcile each other and achieve a state of equilibrium.

The method that Qiao Yu summed up was to replace the flame technique and use the ordinary three-flavor true fire to temper it. In this way, although the refining speed is not as fast as the Flame Technique, the consumption of spiritual power is greatly reduced. The harmony of the two produces a balance, and success is absolutely inevitable.

In countless failed experiences, after summing up all this, Qiao Yu finally understood why Senior Sister used the true fire of foundation building instead of fire attribute spells to refine the wine materials. I'm afraid she's had the same problem as herself, and that's her solution.

It is true that his control over spiritual power is not as strong as that of his senior sister. But as long as he follows this method, he will at most consume more spiritual power than his senior sister, but in the end, it will be completely enough to achieve the expected efficiency.

All the problems suddenly became clear, and Qiao Yu almost did not hesitate, and started a new attempt. And since he started this time, all the previous attempts have already consumed five days in reality. In other words, six days have passed since the January period. And he's still trying in his dreams.

However, there is the experience of previous failures, as well as the problems and solutions that have been summarized. This time, even in his dream, Qiao Yu only took one day to successfully refine all the twenty-five materials. The whole process, in reality, only took more than an hour.

Finally reaching the expected efficiency, Qiao Yu immediately got excited out of the dream and woke up from reality again.

"It's been six days, and it looks like I'm going to have to hurry. After waking up, Qiao Yu muttered to himself, and immediately rushed to Ding's side, followed the steps he tried in his dream, and began the real tempering.

Countless attempts have created Qiao Yu's skillful skills like a master. From the opening of the tripod to the insertion of medicinal materials, the three flavors of real fire fill the tripod, and the whole process is completed in one go. The strength of the flame is just in place, not half a slight.

One day later, the twenty-five materials, as expected, were successfully refined. After the spiritual power is breathed, Qiao Yu is in a state of fullness. Immediately lift the pot to the side of the blood pool and gently place it into the pool. The spiritual power operated, and began to frantically inject spiritual power into the wine vessel.

At one time, almost ninety percent of Qiao Yu's spiritual power was consumed before the qi induction effect of the wine vessel was finally stimulated. The blood in the pool of blood is swirling in the wine vessel, fermenting the koji.

The process doesn't end there. Qiao Yu took advantage of the fact that the effect of the wine vessel was still stable, and hurriedly meditated and breathed. Sensing that the effect of the wine vessel was gradually decreasing, he hurriedly withdrew from the pranayama state and injected spiritual power into the wine vessel again.

In this way, the effect of constantly stabilizing the sake vessel is passing day by day. For two whole days, Qiao Yu finally succeeded in fermenting the koji. The first step was successfully achieved with the expected efficiency of two days.

"I didn't expect it to take eight days, and it looks like I'm going to have to move faster. Qiao Yu looked at the fermented koji, wiped the sweat on his forehead, and then returned to the corner again, lay down quietly, and started a new dream control process.

In his previous plan, he tried to do it in a dream for six days and then two days to complete the first step. The whole process will take eight days. Originally, he had planned to achieve efficiency beyond what was expected, but now it seems a bit far-fetched.

But there is no doubt that his refining skills have really reached the level where he can complete the first step in two days. In the future refining, excluding the time spent trying, he only needed two days to complete the first step, which was a real level improvement.

This is followed by the second step, quenching the wine. This step is the most core part of the entire refining process, and it is also the most difficult step. The so-called "liquor" is the most important core of refining the drunken immortal drink, which is equivalent to the medicinal materials of alchemy.

The rest is the third step, quenching, and the final step, blending all the ingredients and fermenting until completion. "Sake introduction" is to play the role of neutralizing "koji" and "sake ingredients". It is also quite important. Only when the wine is refined and all the wine materials are adjusted can the wine materials be integrated and fermented. However, the process is much easier than refining the "liquor".

It is still a refining material, but the difficulty increases, and the method will change relatively. And all the attempts, Qiao Yu will be carried out in a dream. This time, he completely mastered the second step of refining, and it took ten days in reality.

You must know that ten days in reality is equivalent to two months in a dream. For Qiao Yu, it can really be described as a world away. In his dreams, he was almost a moment of non-stop madness. Keep trying, go through all kinds of failures, learn from experience, and keep honing yourself. During this period, all kinds of efforts put in, although hard, but also made him really grow.

However, ten days later, when Qiao Yu woke up from his dream and began to refine the wine in reality, he carried out the second step. A subtle change, but it caught his attention. After noticing this unexpected change, his face was joyful, filling almost his entire face.

This change was that he realized that his ability to refine the wine had been quietly improved. Whether it is his mastery of spiritual power, or even the degree of spiritual power itself, he has actually imperceptibly improved.

The second step, which would have taken six days to complete. In the end, when it was completely completed by Qiao Yu, it only took four days.

It was only at this time that he finally realized that refining the Drunken Immortal Drink was not a waste of time at all. It's actually a practice as well. Repeated refining has made his control of spiritual power absolutely substantial. The spiritual power is also constantly depleted, and it has become more powerful and powerful as it is absorbed and replenished like a wolf.

And this also happens to make up for the fatal defect that although he has strong spiritual power, he does not know how to fully master the use.
