Time passed by inadvertently, and the sunrise and sunset were four reincarnations. During these four days, Liu Yu tried his best to ripen the Guiyuan Flower and other spiritual herbs for refining the Qingyuan Pill.

Through the ripening of the black spiritual fields in the Xianfu world, it took about 1,500 pieces of spiritual stones, and a total of 50 pieces of spiritual grass needed to refine the Qingyuan Pill were obtained.

Four days later, Liu Yu closed his eyes and sat cross-legged in the alchemy room, with the Xuanhuang Cauldron not far in front of him.

Gathering energy, holding Yuan and guarding one, he suddenly opened his eyes when his body and spirit were adjusted to a better state.

With a wave of his palm, the True Foundation Establishment Fire appeared and quickly fell below the Xuanhuang Cauldron, and began to preheat the Cauldron.

After a quarter of an hour, the preheating was completed. Liu Yu controlled the first adjuvant to enter the cauldron, and removed the dross to obtain the essence.

Ignite, preheat, refine essence, fuse essence, condense pills, and open the furnace.

The process of alchemy is generally divided into these six steps. Generally speaking, the first three steps are roughly the same, and there will be no major changes.

However, due to the different formulas and different quantities of elixir, different medicinal herbs will have very large differences in medicinal properties, showing completely different changes.

Therefore, the last three steps are the most test of the alchemy master's attainments and experience. Without refining experience, even an alchemy master with extremely high experience and attainments will not succeed in refining a new medicinal pill for the first time.

Since Liu Yu's success rate in refining Yuandan has reached 35%, his level of alchemy has not improved for a long time. This is because he does not have a good teacher, and he almost relies on his own exploration and conclusion.

This is also a helpless move. In just 20 years, the progress from refining the Spirit-gathering Pill in the early stage of Qi Refining to the Jingyuan Pill and Qingyuan Pill in the early stage of foundation building is really shocking. It is a rare sight in hundreds of years. The genius, has this amazing talent.

But only Liu Yu knows that this is entirely due to the experience gained through a lot of practice. The elixir and elixir that have been wasted in refining the elixir over the years are converted into spirit stones, and it is estimated that there are hundreds of thousands of low-grade spirit stones. , so many spiritual stones, even if they are magic weapons, it is estimated that one or two can be bought.

This also made him not dare to reveal his true level of alchemy to others. Even Jiang Qiushui did not know that Jingyuan Pill had never been sold in the Jade Pill Hall. The last few bottles of Jingyuan Pill were inferior pills. , Liu Yu thought about it and still didn't release it in the storage bag.

And the alchemy technique is also one of the reasons why Liu Yu's alchemy technique is stagnant. He is still using the basic alchemy technique, and has long been unable to keep up with the increasingly complex alchemy process, which greatly affects the success rate of alchemy.

Liu Yu attaches great importance to this. Although the Immortal Mansion can ripen the spirit grass, it cannot be wasted arbitrarily. If there are raw materials that cannot be ripened by the Immortal Mansion in the future pill recipe, what should be done?

He has already told Jiang Qiushui to pay attention to this information, and he has also made inquiries between the major shops in and out of Fang City, but there has been no progress.

Each alchemist has his own unique alchemy technique. When teaching apprentices, he often keeps a hand. Generally, it will only be passed on to his own descendants or direct disciples. Unless something happens, alchemists are not short of spirit stones. Will sell their own alchemy techniques.

"We must find a more advanced alchemy technique."

From time to time, Liu Yu controlled the fusion of medicinal properties with a magic trick in her hands, and this thought flashed through her mind.

With the improvement of the level of medicinal pills, the basic alchemy techniques have gradually been unable to keep up with the rhythm, and even started to hold back, which has become an urgent problem to be solved.

Every time Qingyuandan is refined, it takes two hours, whether it succeeds or fails.

Liu Yu compresses the time to comprehend the secrets of the kung fu technique, and spends eight hours every day refining four furnaces of Qingyuan Dan, one hour summarizing the experience of alchemy, and maintaining the daily practice progress and the practice of spells and instruments for the rest of the time.

In this way, after 13 days without sleep, the fifty parts of the spirit grass for refining the Qingyuan Pill were finally exhausted. In the end, two pills were successfully refined, each of which was eight.

However, all the elixirs produced in that furnace were inferior medicinal herbs, and the erysipelas contained ten times more than normal medicinal medicinal herbs, so Liu Yu naturally would not take them.

The medicinal power of Qingyuan Pill is about twice that of Jingyuan Pill, which can save more time in cultivation.

It cost 1,500 spirit stones to ripen through the Immortal Mansion to get 50 copies of spirit grass, and completely successfully refined a furnace of Qingyuan Pill. Accept, I believe that after being familiar with the refining of Qingyuandan, you will be able to return to the original soon.

There are three reasons why the success rate of alchemy is so low. One is that he is not familiar with refining Qingyuan Pill for the first time. Second, it is more difficult to refine Qingyuan Pill.

Liu Yu cleaned the Xuanhuang Ding once, and then came to the practice room in addition to the alchemy room, and sat cross-legged on the futon.

Pour out a Qingyuan Pill from the jade bottle and swallow it with your head up. After the pill is put into the stomach, it will quickly exert its effect and turn into hot medicinal power. Different from the mild medicinal power of Jing Yuan Dan, this medicinal power is both pure and Active, somewhat uncontrolled trend, if left to continue, it is likely to damage the meridians and dantian.

Liu Yu's spirit is highly concentrated, and the fourth layer of Qingyang Gong in his body is fully functioning, suppressing the medicinal power of refining.

The mana continuously carries the scorching medicinal power in a great cycle, turning it into pure spiritual energy, and then slowly absorbs it and converts it into mana.

After the four Great Zhoutian cycles are completed, the impurities in it will be quenched~www.mtlnovel.com~ These new mana will lead to Dantian, pass through the Qingyang Demonic Fire above the lake, and finally merge into the lake of mana.

When the newly born mana passes through the Qingyang Demonic Fire, some impurities will be burned into black smoke and excreted from the body. While it is more pure, the amount of mana will also be reduced by about half.

Three hours later, along with a mouthful of turbid air containing impurities, Liu Yu finished the exercise and opened his eyes, a look of joy flashed on his face.

Qingyuandan is worthy of being an ancient recipe. Its medicinal power is more than twice as strong as that of Jingyuandan. It is true that he spent so much energy collecting spirit herbs.

With the help of this pill, one's own cultivation speed will be greatly accelerated, and the time to cultivate to the peak of the initial stage of foundation building will be further shortened. Liu Yu estimated that if the daily consumption of Qingyuan Pill is used, it will take about fifteen years. The initial peak can be reached on the left or right.

In one adventure, I collected forty or fifty kinds of rare elixir, not only the Qingyuan Pill, but also the Yangyuan Pill that was taken in the middle stage of Foundation Establishment.

"Wealth and honor are sought in danger, and dao fate is taken in danger. The ancients honestly did not deceive me."

Liu Yuxin sighed with emotion that all the medicinal pills used in the early and middle stages of foundation building are available. As long as he doesn't encounter a bottleneck, he can cultivate unimpeded to the later stage of foundation building, which can be described as a smooth road.
