In front of a cliff not far from the valley, Yu Zehai held a sword and quickly dug a cave at a position about four or five meters above the ground on the cliff, and then drilled into it.

"You are free to move around these days, don't disturb me!" Yu Zehai's gaze swept over the faces of the people who were full of sluggishness, and said lightly.

"Understood!"

The crowd shouted in unison.

The stone chamber cave is only about ten square meters, Yu Zehai waved his sleeves, swept all the gravel and dust on the ground out of the cave, and then sat down cross-legged in the center.

Meditate and pranayama.

After a cup of tea, Yu Zehai calmed down and returned to the state of the ancient well without waves.

Alchemy is most taboo to have distracting thoughts, and if there are distracting thoughts, it will affect the judgment of the medicinal properties and the grasp of the timing, and if there is a slight mistake, all the hard work will be in vain. Although Yu Zehai is the first time that the eldest girl has been on the sedan chair, Yu Zehai has long known the "Nine Volumes of Dandao" left by the old man in the border wilderness, and the melon is ripe.

Yu Zehai took out the Dan furnace from the storage ring, and then wiped his fingers, and suddenly a large number of medicinal herbs surrounded him. Inspect the furnace, sort and sort the herbs...... What Yu Zehai wants to refine this time is the most common quenching pill among the first-grade pills.

The pills are divided into nine grades, and the pills of each grade are divided into four sub-grades: inferior, medium, high and special according to the degree of purification of the medicinal materials. For example, this quenching pill is a first-grade pill, but in the end, it becomes a pill grade, on the one hand, it depends on the quality of the medicinal materials, and on the other hand, it depends on the real talent of the alchemist.

It is also a first-grade elixir, but the difference between a first-grade inferior and a first-grade medium, high, and special grade is not a star and a half. The better the purification of the medicinal materials, the higher the grade of the pill, and the higher the grade of the pill, the less impurities it contains, and the higher the utilization rate of the warrior after taking it.

Yu Zehai stroked the alchemy furnace in front of him, only to see that he slapped the alchemy furnace wall, and the yuan fire in his body was instantly stimulated, and it burned with a "boom", and the blazing white flames burst up in an instant, wrapping the entire alchemy furnace into the raging flames.

It's just that this kind of flame has no effect on Yu Zehai now. He knew that now he only needed to continuously infuse a certain amount of vitality to keep the flame burning.

"Mo Fang, steady!"

Yu Zehai's mouth was fragmented.

An important technical indicator of an alchemist is fire control. Control the output speed of the vitality to adjust the size of the flame, otherwise, the vitality in the body will be consumed, and it may not be able to refine an elixir.

For example, in the process of refining, the flame is too small to refine the medicinal materials, and if the flame is too large, it will harm the essence of the medicinal materials.

When the Ding furnace was burned red, Yu Zehai's empty right hand made a move, and a medicinal herb was thrown into it, but before Yu Zehai could react, the medicinal herbs in the furnace had already spent ashes.

Nima!

Yu Zehai extinguished the flame and poured out the burning residue. Then clean the alchemy furnace and start refining again.

The scene just now, Yu Zehai was already used to it.

Think about it, the first time you grope for alchemy, how can you succeed at the first time? The use of vitality is not skillful enough, and the mastery of heat is biased. This is only the refining stage, if the later medicinal materials are purified, the requirements must be more precise, once there is any deviation, the medicine tripod explosion is common, and even more, the explosion of the tripod furnace will involve people and fall down.

"Bang ......"

Moments later, the same scenario played out.

Slowly, the cave began to fill with smoke. Yu Zehai ignored this and continued to focus on refining.

Fail!

Fail!

Fail again!

......

Failure again and again, the waste of medicinal materials is a trivial matter, mainly because the vitality in Yu Zehai's body has been consumed.

Sharpen the knife and do not mistake the woodcutter.

Yu Zehai poured himself a cup of spiritual spring, then pinched the formula in his hand and began to meditate and breathe.

The process of alchemy not only requires a lot of vitality, but also because the situation in the alchemy furnace is constantly monitored, the divine consciousness in the mind is also depleted at an extremely fast rate.

But despite this, Yu Zehai's face is still calm, his heart is like water, and he is not angry. Because, in his failures just now, Yu Zehai's control of the fire, the refining of medicinal materials, and the purification of medicinal liquids are gradually becoming proficient, and with the failure and summary again and again, this shows that he is getting closer and closer to success.

The first step is to refine medicinal herbs!

The second step is to purify the liquid medicine!

It's just that the purification process is a crucial step in the entire alchemy process.

Remove turnips, remove impurities, and leave essence.

The quality of the final formation of an elixir mainly depends on the degree of purification of the medicinal materials by the alchemist. If the purity reaches more than 90 percent, there is a high probability that there will be a special elixir, 80 percent, high-grade elixir, 70 percent, medium elixir, and 60 percent, inferior elixir...... If the purity is too low, then the refined one is not called an elixir, but a poison.

The third step is the fusion of the liquid medicine!

This link pays more attention, such as the order of fusion, the order is not right, it will definitely not work, alchemy pays attention to the main and auxiliary of the monarch and the minister, and the second is the understanding of the medicinal properties of medicinal materials. If it is mutually restrictive, it needs to be neutralized by neutral adjuvants. In addition, among them, it is necessary to test the alchemist's mentality, fire control ability, alchemy techniques, and comprehension.

When all the medicinal materials were taken from their essence and their dross, and purified into small clusters of medicinal liquid, Yu Zehai carefully controlled these medicinal liquids to begin to fuse according to the order on the Dan Fang.

With the experience and lessons of repeated defeats and repeated defeats before, Yu Zehai felt exceptionally smooth this time. In just a stick of incense time, a faint medicinal fragrance diffused from the Dan furnace, and the quenching pill in the Dan furnace has formed a prototype, and the alchemy has been carried out to the last step at this time, and it is about to be completed!

"Bang!"

Suddenly, with a muffled sound, a thick burnt smell came out, and under Yu Zehai's gaze, the prototype of the pill in the Dan furnace burst open, and it was instantly burned into a ball of black slag!

Yu Zehai was discouraged, and the whole person was a little dazed.

Damn it!

Yu Zehai was puzzled.

It stands to reason that he deliberately controlled the rhythm this time, from refining, purifying, to fusion, there was no problem, why did he fail in the link of Ning Dan? You know, every step of this is step-by-step, Yu Zehai can be said to be careful and careful, every little detail is carried out in a proper manner, but who would have thought that in the process of Ning Dan, it still failed.

"There are no problems with refining, purifying, and fusing them, and the refining process is extremely smooth, why do you always fail in the link of condensing pills?"

Yu Zehai pinched the elixir waste residue in his hand, frowned, and fell into deep thought. Just now, I was obviously only one step away from becoming a Dan completely, but in the end, I fell short and exploded!

Just when Yu Zehai entered the stall of meditation and pranayama with a spirit stone in his hand, not far from the bottom of the cave, Wang Lang and his party were getting together and discussing in a whisper.

"Brothers, guess what our boss is doing?"

"It must be some kind of black technology research!"

"Smell it, the burnt smell is getting heavier!"

"Hey, there's smoke in the cave!"

......

"Shhhhhh ”

Wang Lang raised his hand and knocked on the door of several people's heads, and said angrily: "Stop, if you are bored, get away." People who practice martial arts have very sharp five senses, not to mention the boss, even if it is me now, the crickets in a radius of 50 meters nearby can't hide it from my ears. Do you think that in this position of our brothers, the boss will not hear what you are talking about?"

"Uh......"

Hearing Wang Lang's words, several people covered their mouths together.

"Alright, you guys all get out, I'll just guard here. Wang Lang waved his hand and said, "Anyway, there is no danger on this island, you each find a place to play JJ, and by the way, see if you can get some game back." But try not to go to the beach, otherwise it will be swept away by a typhoon and it will be over. ”

"I'll stay too. ”

Seeing this, Yu Zejun next to him pondered for a few seconds and said: "It's best for the three of you to go together, and besides, you must not go to the windward place, it is not a joke to face the typhoon." Once you are captured by a typhoon, sea burial is your best destination. ”

"Ahh

An hour later, the exhaustion on Yu Zehai's body was swept away. It's just that what he didn't notice was that after such repeated consumption and recovery, the vitality in his body had actually improved slightly, but the loss of divine consciousness needed time to slowly recover.

In the following time, Yu Zehai plunged headlong into the world of alchemy, and his people repeatedly accepted the baptism of failure and explosion, but his people still had no previous peace and indifference.

Alchemy is also a kind of practice.

It was only at this moment that Yu Zehai understood that alchemy was not only an extremely useful life skill, but also had a very significant effect on cultivation, especially the cultivation and improvement of the state of mind. At this point, Yu Zehai seems to have figured it out, no wonder an existence like the old man in the border wilderness who stands at the peak of the cultivation world, not only cultivates to the sky, but also is proficient in alchemy, refining, formations, and so on.

There are thousands of avenues, and different paths lead to the same end.

When a person's cultivation has reached a certain level, his every move, word and deed is all about his practice, and he is not practicing all the time.

When walking, most of the exercises are light body kung fu, as well as a sense of vigilance and sensitive touch, at the same time, you can also practice the eyes and ears, body touch, when fighting, it is a state of mind exercise, when you are lonely, it is the tempering of your will, and when it is lively, it is the best cultivation environment to keep your mind like water...... Just like Yu Zehai's alchemy at this time, through repeated consumption and recovery, the vitality and divine consciousness in his body have not only grown greatly, but also become more condensed and more handy to use.

This is cultivation!
