Yun Xian Dan, refining one furnace, it takes almost seven days, plus the time of rest, at most four furnaces can be refined in a month, one hundred points of materials, and it will take almost two years to complete the refining.

Biqiong Elixir, it takes almost twelve days to refine one furnace, and two furnaces can be refined in a month, thanks to that, it will take less than four years to complete the refining.

Alchemy requires a lot of immortal spirit power, which is equivalent to constantly needing immortal spirit crystals to replenish, if it weren't for the thousand immortal spirit crystals that Ouyang Qian gave after joining the Ouyang family, I am afraid that I would have to sell some pills first.

Yun Xian Dan, with the improvement of Lin Tianyang's cultivation, when refining at the beginning, the success rate can reach nearly seventy percent, and each successful furnace can almost become two and a half pills or a little more, and when refining more than fifty furnaces, perhaps because practice makes perfect, not only the refining time has been shortened, but the success rate has also increased a lot, more than eighty percent of the success rate, plus the Cheng Dan rate of more than three pills per furnace, zuihou When Lin Tianyang finished refining all the hundred furnaces of pills, plus the probability of Hongling refining, he finally got two hundred and eleven Yun Xian Pills。

This result made Lin Tianyang very satisfied, in fact, even if it was Hongling, under the current cultivation limit, she would be able to reach more than ninety percent of the Cheng Dan rate, and more importantly, each furnace of Cheng Dan was more than three pieces.

With such a result, even Hong Ling was shocked.

With this kind of self-confidence, Lin Tianyang next refined the Biqiong Immortal Pill, and the success rate was not low with Liu Cheng, and each furnace could almost produce two pills, and later thirty or forty furnaces, the success rate increased to more than seventy percent, and each furnace of Cheng Dan also increased by as much as half a piece, Zuihou added several furnaces of pills refined by Hongling, and obtained one hundred and sixty-eight Biqiong Immortal Pills, which was already very close to the average nine-grade alchemist.

It's just that some pills have been refined. It took such a little time to have such a result, and when Hong Ling looked at Lin Tianyang again, she already completely regarded him as a freak.

Because Lin Tianyang didn't keep refining the pills, but added his own research and experience to the refining, so when all the two hundred materials were refined, it took him more than seven years.

There were more than two years left, Lin Tianyang directly swallowed the excess Yun Immortal Pill to cultivate, and after a long period of alchemy, Lin Tianyang found that although his mana had not increased much. But the divine sense seems to have grown a little, although it is not much, but this is only the result of a few years of alchemy, if it continues for a long time, Lin Tianyang believes. His own divine sense may become even stronger.

After the ten years were over, Lin Tianyang left his cave again. Arrived at the fairy town market. found Ouyang's shopkeeper, handed him his refining haode pill, and then took the same amount of materials from him, and the refining conditions did not change.

After returning to the cave mansion, this time it only took Lin Tianyang more than five years to refine all the pills.

This time refining. The success rate of his own Yun Xian Dan has been further increased a little, and by the time of Zuihou's twenty or thirty furnaces, it has reached eighty percent five, and each furnace has reached nearly half of three pills, and Zuihou has obtained two hundred and fifty-six Yun Xian Dan. This achievement, among the Nine Rank Alchemists, is not bad.

The refining of Biqiong Xian Dan has also been improved a lot, the Cheng Dan rate has reached nearly eighty percent, and each furnace has produced more than three pills, and Zuihou has obtained two hundred and eighteen Biqiong Xiandan, this result, even among the nine alchemists, is already very good.

Because there were a lot of pills left over from this alchemy, Lin Tianyang thought about it, and after finding Ouyang's shopkeeper, he took out thirty of them and sold them directly.

For Lin Tianyang to be able to take out thirty Biqiong Immortal Pills, Ouyang Shopkeeper was not too surprised, after all, this was the elixir that Lin Tianyang took out after two alchemies.

And Lin Tianyang also received the same materials again, but in addition, he also got the fairy spirit crystals that Ouyang's shopkeeper paid Lin Tianyang in advance for thirty pills, a total of 12,000 fairy spirit crystals.

Of the 12,000 immortal spirit crystals, Lin Tianyang got 100 medium-grade immortal spirit crystals and 2,000 low-grade immortal spirit crystals.

Compared with the low-grade fairy spirit crystal, the fairy spirit power contained in the middle-grade fairy spirit crystal is naturally more pure and vigorous, and it itself looks more crystal clear and transparent than the low-grade fairy spirit crystal.

After getting the Zhenduo Immortal Spirit Crystal, Lin Tianyang immediately entered the Tower of Babel first, and paid off the debt owed to Tongtian Lao Dao, and the absence of debts made Lin Tianyang suddenly relax a lot, and when refining the elixir of the third mission, he seemed to be more handy.

In the third task, when all the two hundred furnaces of pills were refined, Lin Tianyang's success rate in refining the Yun Xian Pill had reached nearly ninety percent, and each furnace of the pill had almost reached three and a half pieces, slightly more, and Zuihou had obtained two hundred and eighty-two Yun Xian Pills.

The success rate of Biqiong Elixir is also more than eighty percent, and each furnace is close to three and a half pills, and Zuihou has obtained two hundred and forty-eight Biqiong elixir.

At this level, it can be said that among the nine-rank alchemists, it is already very powerful, and even Hong Ling herself admits that she has not reached such a rate before becoming an official nine-rank alchemist.

With so many pills, when Lin Tianyang went to find Ouyang's shopkeeper, in addition to giving him another thirty Biqiong Immortal Pills, he also gave him one hundred Yun Immortal Pills to sell, and obtained a total of 17,000 Immortal Spirit Crystals.

This time, because Lin Tianyang seemed to have too many pills, the shopkeeper Ouyang was also a little surprised.

After Lin Tianyang saw his surprised look, he felt in his heart that maybe the next time he came back, he might have changed a little.

After getting the same amount of materials again, and returning to the cave mansion, Lin Tianyang began refining the pill again.

After refining the pill this time, Lin Tianyang found that whether it was Yun Xian Dan or Biqiong Xian Dan, he seemed to have reached a limit, Yun Xian Dan was no longer able to improve after reaching the ninety percent Cheng Dan rate, and the Cheng Dan rate of Biqiong Xian Dan was also maintained at eighty percent five, but the number of pills produced in each furnace increased slightly, Yun Xian Dan has reached nearly four, and Biqiong Xian Dan has also reached three and a half pieces, Zuihou Yun Xian Dan has gained three hundred and sixteen pieces, and Biqiong Xian Dan has obtained two hundred and eighty-four pieces.

At this time, Lin Tianyang also estimated that even if he refined these two pills in the future, if there was no major breakthrough, even if he refined more, I am afraid that he would not be able to improve it again.

When the time reached ten years again, Lin Tianyang finally came to the store again, and this time after finding the shopkeeper Ouyang, Lin Tianyang still gave him the required amount of pills, but the shopkeeper Ouyang told Lin Tianyang to wait for a while.

Lin Tianyang knew that it was probably because of what happened last time that the Ouyang family reacted, and sure enough, not long after, Ou Yaqian appeared in front of him again, and this time it was no longer the doppelganger of the late stage of the True Wonderland, but the doppelganger of the middle stage of the True Wonderland.
