Immortal Palace Longevity

Time always passes by inadvertently, and the sun rises and sets, and it is another four reincarnations. During these four days, Liu Yu tried his best to ripen the Guiyuan Flower and other spiritual herbs for refining Qingyuan Dan.

Through the ripening of the black spiritual field in the Immortal Mansion World, it cost about 1,500 spiritual stones, and a total of 50 spiritual herbs needed for refining Qingyuan Dan were obtained.

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

Gathering Qi and concentrating his mind, holding Yuan and guarding oneness, he suddenly opened his eyes when his body and mind adjusted to a better state.

With a wave of his palm, the foundation-building true fire appeared and quickly floated down to the bottom of the Xuanhuang Ding, and began to preheat the cauldron.

After half a quarter of an hour, the preheating was completed, and Liu Yu controlled the first auxiliary medicine to enter the cauldron, removing its dross and taking its essence.

Ignition, preheating, extracting essence, fusing essence, condensing the pill, and opening the furnace.

The process of alchemy generally consists of these six steps. Generally speaking, the first three steps are roughly the same and there will not be much change.

However, different pills have very different medicinal properties due to different formulas and different amounts of spiritual medicines, presenting completely different changes, and there will be great differences in the integration of spiritual medicine essences, pill-condensing techniques, and furnace opening time.

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

Since Liu Yu's success rate in refining Jingyuan Dan reached 35%, his alchemy level has not improved for a long time. On the one hand, this is because he has no good master and relies almost entirely on his own exploration and summary.

This is also a helpless move. In just 20 years, from refining the Juling Dan in the early stage of Qi Refining to the Jingyuan Dan and Qingyuan Dan in the early stage of Foundation Building, the progress is really shocking. It is simply a rare genius in hundreds of years, and only such an amazing talent can be seen.

But only Liu Yu himself knew that this was entirely due to the experience gained from a lot of practice. The spiritual medicines that were wasted in the past few years for refining pills were converted into spiritual stones, which was estimated to be hundreds of thousands of low-grade spiritual stones. With so many spiritual stones, even if it was a magic weapon, it was estimated that one or two items could be bought.

This also made him dare not reveal his true level of alchemy to others. Even Jiang Qiushui did not know that Jingyuan Pills had never been put on sale in Yudan Hall. Liu Yu thought about it and kept the inferior pills of the last few bottles of Jingyuan Pills in the storage bag without releasing them.

The alchemy technique was also one of the reasons why Liu Yu's alchemy was stagnant. He was still using the basic alchemy technique, which had long been unable to keep up with the increasingly complex alchemy process, greatly affecting the success rate of alchemy.

Liu Yu attached great importance to this. Although the Immortal Palace could ripen spiritual herbs, they could not be wasted at will. If there were raw materials in the future pill recipes that could not be ripened by the Immortal Palace, what should he do?

He had already told Jiang Qiushui to keep an eye out for information in this regard, and he had also asked around in the various shops in the market, but there had been no progress.

Each alchemist has his own unique alchemy technique, and he would often keep a few of them when teaching his apprentices, and would generally only pass them on to his direct descendants or disciples. Unless something unexpected happened, the alchemist would not be short of spirit stones and would not easily sell his own alchemy technique.

"We must find a more advanced alchemy technique."

Liu Yu made spells in his hands from time to time to control the fusion of medicinal properties, and this thought flashed through his mind.

With the improvement of the elixir level, the basic alchemy technique has gradually failed to keep up with the pace, and even began to lag behind, becoming an urgent problem to be solved.

It takes two hours to refine each furnace of Qingyuan Dan, whether it succeeds or fails.

Liu Yu compressed the time for comprehending the secrets of the skills, spending eight hours a day refining four furnaces of Qingyuan Dan, one hour summarizing the alchemy experience, and the rest of the time maintaining the daily practice progress and practicing spells and instruments.

After thirteen days of sleepless nights, the fifty spiritual herbs for refining Qingyuan Pills were finally used up. In the end, two pills were successfully refined, and eight pills were condensed each time.

But the later furnace produced only inferior pills, and the poison contained in the pills exceeded the normal pills by ten times, so Liu Yu naturally would not take them.

The power of Qingyuan Pill is about twice that of Jingyuan Pill, which can save more time for cultivation, and is worth about 1,200 to 1,300 spiritual stones per bottle.

It cost 1,500 spiritual stones to ripen fifty spiritual herbs through the Immortal Palace, and successfully refine a furnace of Qingyuan Pills, which is worth about 1,000 spiritual stones. It only lost 500 spiritual stones. This price is completely acceptable to Liu Yu. I believe that after becoming familiar with the refining of Qingyuan Pills, it will soon pay off.

There are three reasons for the low success rate of alchemy. One is that I am not familiar with refining Qingyuan Pills for the first time. The second is that refining Qingyuan Pills is more difficult. The third is that the alchemy technique has been delayed.

Liu Yu cleaned the Xuanhuang Ding, then left the alchemy room and came to the training room, sitting cross-legged on the futon.

He poured out a Qingyuan Pill from the jade bottle and swallowed it. The pill took effect quickly after entering his stomach, turning into strands of hot medicinal power. Unlike the mild medicinal power of the Jingyuan Pill, this medicinal power is both pure and active, and has some uncontrolled trends. If it is allowed to continue, it is likely to damage the meridians and Dantian.

Liu Yu was highly focused, and the fourth level of Qingyang Gong in his body was fully running to suppress and refine this medicinal power.

The mana continued to carry the hot medicinal power for the big circle circulation, turning it into pure spiritual energy, and then slowly absorbed and converted into mana.

After the four big circles were completed, the impurities in it were refined, and the new mana led to the Dantian, passed through the Qingyang Magic Fire above the lake, and finally merged into the mana lake.

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

Three hours later, with a mouthful of turbid air containing impurities being exhaled, Liu Yu finished practicing and opened his eyes, with a hint of joy on his face.

Qingyuan Pill is indeed an ancient recipe. The medicinal power is more than twice as strong as Jingyuan Pill. It is indeed worth spending so much energy to collect spiritual herbs.

With the help of this pill, his 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 he continued to take Qingyuan Pills every day, he would be able to reach the peak of the initial stage in about fifteen years.

In one adventure, he collected forty or fifty kinds of rare spiritual medicines. Not only did he collect Qingyuan Pills, but he also collected Yangyuan Pills for the middle stage of foundation building. I believe that he should be able to collect all of them during this period of time when he cultivates to the peak of the initial stage of foundation building.

"Wealth and honor are sought in danger, and Taoism is achieved in danger. The ancients did not deceive me."

Liu Yu was moved. He had all the elixirs needed for the early and middle stages of foundation building. As long as he did not encounter bottlenecks, he could practice to the late stage of foundation building without any obstacles. It was a smooth road.
