Yu Sanzu breathed for three hours before he recovered.

If Zhihai is injured, it will affect the spirit, and there will be endless troubles in the future. The most important thing is that the cultivation realm does not have a direct healing elixir for injuries to the sea of consciousness and damage to the spirit, although there are some spirit plant treasures that can assist the injury, but the effect is not very good.

Under normal circumstances, if Zhihai is injured, as long as it has not reached the level of damage to the spirit, it can gradually recover by slowly adjusting his breath on his own, but the time is over the years, depending on the degree of injury.

But if it is a damage to the divine spirit, there is basically no solution, unless it is a super power, willing to help at the cost of depleting his divine consciousness cultivation. But this method of healing is thrilling for both parties.

Therefore, once the monk's spirit is damaged, the consequences are very serious, the light ones will be damaged, the heavy ones will fall to mortals, and even die.

Yu Sanjin knew the severity of Zhihai's injury, but he couldn't solve it at the moment, so he could only let it go for the time being. Fortunately, he is a fusion of two souls, and his spirit is much stronger than ordinary people, so the impact can be minimized.

Yu Sanjin carefully checked his own sea of knowledge, and found no abnormality, only to see the center of the sea of knowledge, the creation of the Qiankun coin domineering suspended in the air, and the refining source Danxin was squeezed to the edge.

He didn't continue to entangle himself in the sea of knowledge, harnessing the refining source pill heart, wrapping the spirit grass, and carrying out a new round of practice.

After a round of pranayama, he found that his divine sense had actually improved, and his control over the refining source pill heart had gradually become familiar, and he could basically control the running path of the spirit grass.

It is not a matter to practice like this, after all, alchemy is to be operated in a Dan furnace, and the temperature and heat inside are different from those outside, and there are air flow interferences, so you must adapt to them.

Yu Sanjin introduced the spirit grass wrapped in the refining source Dan heart into the Dan furnace.

As soon as he entered the Dan furnace, the surging high temperature caused the spirit grass to stagnate, and he almost fell out of the control of the remaining three catties of divine consciousness.

He was not in a hurry, and hurriedly strengthened the tension of Danxin, resisting the interference of the high temperature airflow, and was able to survive this crisis.

Then the problem came again, because he was not familiar with the temperature in the Dan furnace, some spirit grasses began to wither, and symptoms of dehydration appeared.

Yu Sanjin controlled the Danxin and avoided the high temperature area, so that the heating surface of the spirit grass became balanced, and the damaged condition of the spirit grass was improved.

After stabilizing the suspended spirit grass, it was time to try alchemy.

Alchemy is an extremely powerful Dan method, and there is no need to quench it like other Dan methods, one by one, and then refine it, and then condense it, cut it, become it, and start it.

Alchemy can seamlessly connect all links, it relies on the miracle of the alchemy pill heart, and completely controls the alchemy materials.

This kind of alchemy avoids the long-term consumption of alchemists, and also saves some unnecessary troubles, making the refining of the spirit grass more complete, and the fusion between different spirit grasses can be maximized, which greatly promotes the quality of the elixir.

Yu Sanjin used the "Alchemy Technique" to lay down a pill trick, only to see the refining source pill heart bloom with a hazy light, shrouded in the six kinds of spirit grass, and began to refine.

This change made him extremely happy, it turned out that Dan Xin had to cooperate with Dan Jue in order to change form and fit with the spirit grass.

It is said that it is a Dan heart, but in fact, it contains the Dan Dao endowment of "Alchemy", which is conceived in the sea of knowledge of the inheritor and grows together with the alchemist. Yu Sanjin has a preliminary understanding of "Alchemy".

What a Dan Dao inheritance! Yu Sanjin sighed involuntarily.

The six elixirs in Dan's heart changed visibly with the naked eye, and the herbal essence flowed to the center along the veins cast by Dan's heart, gathering together without interference, and the liquid mass was colorful and very dazzling.

Yu Sanjin realized that it turned out that the use of alchemy to refine the spirit grass was not to directly quench the spirit grass in a high temperature, but to gather the temperature on the Dan heart first, and then refine the spirit grass through the Dan heart.

No wonder this alchemy method is so powerful, not only is the success rate extremely high, but the quality of the refined pill is also outstanding, and the feelings have long been set routine.

As long as the Dan Heart is conceived, and then combined with the corresponding Dan Jue, the inheritance endowment of the "Alchemy Technique" can be activated. This kind of alchemy inheritance is tantamount to cheating, like alchemy that has been directly initiated.

The only regret is that the Dan Heart grows with the growth of the inheritor, that is to say, Yu Sanjin is limited by his own cultivation and divine sense, otherwise, he is fully confident that he can refine a high-grade pill.

The refining of the spirit grass continued, and Yu Sanjin reviewed the "Alchemy Technique", and another Dan trick was struck.

I saw that Dan Xin suddenly turned into the appearance of the mysterious Dan furnace, the turtle was lifted, and the green dragon was galloping. The two turtles spat out a crystal purple light from their mouths, shrouded in the liquid mass, and slowly swallowed the liquid mass.

Immediately, the two green dragons spit out wisps of brilliant herbal essence, slowly converging in the center, and finally, the volume of the liquid mass was actually reduced by half, but it looked very delicate, and the impurities were obviously much less.

"Your sister, what the hell is going on? How did the Dan Heart transform into a mysterious pill furnace? And the Xuan Turtle swallows the medicine, and the Qinglong spits the medicine, and it can still be purified!" Yu Sanjin muttered, "That's right! Purify! The so-called alchemy technique is naturally the origin of refining spiritual things!"

Yu Sanjin suddenly realized, overjoyed, no wonder he could improve the level of any spiritual thing, and the emotional family played this Dan Dao is the origin!

"Hahaha......" Yu Sanjin laughed heartily, this source alchemy made him surprised.

He forced himself to calm down, after all, he was still alchemizing at the moment, and it was easy to affect the result of alchemy.

In a few moments, the essence of the plants and trees in the Dan furnace has been quenched, and the colorful liquid mass is extremely pure, blooming with a soft light, which is reflected around the second form of the Dan heart, which is very dazzling.

With the success of refining the source, the Dan Heart gradually returned to its first form, enveloping the mass of grass and tree essence so that it could be evenly heated.

According to the steps of "Alchemy", Yu Sanjin made a pill trick in time, only to see the Dan heart rotate at high speed, and after a while, it was very natural to divide the group of herbal essence into twelve groups.

These twelve clusters of herbal essences, each of which has the same amount of weight, does not have a trace of cumbersomeness, and does not stick, as if it has been carefully calculated and then differentiated.

In fact, alchemy is not completely without steps, but it can simplify the complex, making the entire alchemy technique more reasonable, the process smoother, and the results more controllable.

For example, in the process of Chedan, the common method is to wait for the liquid mass to solidify before Chedan, which can ensure that the material will not overflow and evaporate, thus causing unnecessary wear and tear.

However, the alchemy technique relied on the anti-heaven pill heart, and there was no such concern at all, and it could be divided into twelve parts in advance in the liquid mass form, so that the distribution of the essence of plants and trees was more even, and the quality of the pill was more guaranteed.

The most important thing is that the ordinary Danfa Chedan can only be used for six parts, but the Alchemy Chedan is twice as much, reaching twelve. This kind of quantitative change may not be much in the eyes of ordinary people, but in the eyes of alchemists, it is simply against the sky.

Just imagine, it is a common practice in the industry to have six Cheng Dan in one furnace, but the profit is scary enough. And the source alchemy, one furnace into twelve pills, it is not an ordinary money-making, and it is not an exaggeration to say that it is a money-grabbing.

Yu Sanjin was only in contact with alchemy for the first time, so naturally he didn't have this concept yet. Only after he tastes the sweetness can he have this kind of awareness.

The twelve clusters of grass and tree essence in Dan's heart were filled with soft light, suspended in the Dan furnace, like six twinkling stars.

Thanks to the protection of Danxin, even if the liquid mass has been left for a long time, it has no loss and has always maintained its most perfect state. If it was an ordinary pill method, it would have turned into coke a long time ago, or even a fryer.

Refining the source Dan heart is indeed a mysterious Dan Dao inheritance, which is beyond the scope of ordinary Dan masters' understanding of Dan Dao.

It's time to complete this alchemy, Yu Sanjin is another pill trick, and I saw Dan's heart tremble violently, and it instantly glowed with dazzling light.

And the twelve clusters of herbal essences, arranged in an orderly circle, around the heart of the Dan, slowly rotated, as if twelve small planets were revolving around a big planet.

This strange phenomenon reveals a mysterious charm, as if it is secretly in line with some kind of avenue, but it is difficult to grasp if it is immediately separated.

The rotation of the liquid mass slowly accelerates with the degree of solidification. The whole process goes from slow to fast, from slow to urgent, and finally becomes impossible to capture with the naked eye.

After about half a pillar of incense, the Dan furnace became calm. I saw twelve crystalline pills surrounding the pill heart, which was slightly smaller than the ordinary pills, but it was obviously much more delicate.

Yu Sanjin used his divine consciousness to guide Dan Xin out of the Dan furnace. Danxin carried twelve pills, suspended in the air, still orderly and round, very magical.

Yu Sanjin stretched out his hand and pinched one of the pills, held it in the palm of his hand and looked at it carefully, only to see that although the real pill was a little smaller, it was very round, and there was even a pill halo around it.

However, all pills are distinguished by Dan halo to distinguish quality, inferior pills do not have Dan halo, medium pills have one Dan halo, high-grade pills have two Dan halos, and special pills have three Dan halos.

The pill in Yu Sanjin's hand has a Dan halo on it, which proves that it is a medium-grade true pill. The first alchemy made a medium pill, and if this was to be said, it would be unbelievable.

Yu Sanjin knew in his heart that in the process of alchemy, he used alchemy to improve the purity of the elixir. Therefore, only then can the medium elixir be refined.

He was overjoyed, after all, he had personally refined the Yipin Hui True Pill, and he was now a justifiable Yipin Dan master.

"By the way, isn't the source alchemy technique able to improve the grade of the elixir?Why don't you take the opportunity to try it?" Yu Sanjin's mind quickly turned, and he became more and more excited.

He filled two pills with jade, and then guided Dan Xin to wrap the remaining ten pills into the pill furnace.

The inheritance memory of the Alchemy Technique indicates that as long as there are ten times as many low-level spiritual objects, a higher-order spiritual object can be refined. For example, as long as you use ten first-grade Huizhen Pills, you can refine one second-grade Huizhen Pill.

The price of the second grade of the pill is ten times more expensive than the first grade of the pill? After all, his current cultivation was already in the middle stage of Lingyun, and if he could take the pill he had refined, he would have a great sense of accomplishment!
