After figuring it out, Lin Wan waved his hand to take out the charred slag in the Dan furnace, and performed a cleaning technique to clean up the inside of the Dan furnace, and Lin Wan continued to practice his alchemy career.

The second time the refining of Huanglong Dan failed.

The third refining of Huanglong Dan failed.

The fourth refining of Huanglong Dan failed.

For five days in a row, Lin Yun failed to refine the Yellow Dragon Pill for more than a dozen furnaces, but did not succeed in one furnace, at this time, Lin Yun's body was messy, and there was a black piece on his face, but Lin Yun didn't care, and looked at the seven Yellow Dragon Pills in his hand stupidly.

Lin Yun refined seventeen furnaces of Huanglong Dan, and only then did he succeed in one furnace of Huanglong Dan came out, it can be seen how challenging the spirit pill is, and the success rate and low Dan rate are scary, but these did not discourage Lin Yun's enthusiasm, since he got the spirit ring, his life has become different, if he can't hold on to a small test, what kind of immortal can he cultivate, it is better to go home and give birth to a child and take someone to go.

Lin Yun felt that in the past few days, he had refined the Huanglong Dan by himself, his divine consciousness had become more and more condensed, and his spiritual power had become more and more refined, and the time for refining the Huanglong Pill had gradually shortened, and it originally took three hours to refine the Huanglong Dan in one furnace, but now it has been shortened to two hours and forty minutes.

Lin Yun carefully put the seven Yellow Dragon Pills in his hand into the wooden box he carved, then closed his eyes and ran the exercises, slowly recovering the spiritual energy consumed.

After this, Lin Yun recovered his aura and continued to refine the remaining dozen or so elixirs for refining the Yellow Dragon Pill, and all of them were refined into the Yellow Dragon Pill.

The remaining eighteen furnaces of Huanglong Dan, because Lin Wan is becoming more and more proficient in refining Huanglong Dan, among the remaining eighteen furnaces of Huanglong Dan, Lin Wan has succeeded in seven furnaces of Huanglong Dan, and the success rate has reached half, and each furnace of Huanglong Dan is seven grains, plus one furnace of Huanglong Dan that was successfully refined before.

Lin Yun saw that his success rate was so high, and he thought in his heart that his sister still had a talent for alchemy.

If the alchemists of the earth knew that Lin Wan had failed to refine so many times and had wasted such a spiritual herb elixir, he would have been angry with Lin Wan and would have scolded the loser, and he still had the talent for alchemy, and he would have despised the moonlit night.

Lin Wan has a total of fifty-six Yellow Dragon Pills, but most of these fifty-six Yellow Dragon Pills are low-grade elixirs, and a small part are medium-grade elixirs.

As for the elixir, it is divided into lower grade, middle grade, upper grade and best grade, among which the difference in grade, the efficacy of the medicine is different, the higher the grade of the pill, and the erysipelas in it is much less.

Lin Wan opened his mouth and inhaled, and a grain of Qi Refining Pill fell into Lin Yun's mouth, and the Huanglong Pill turned into a stream of extremely pure aura, flowing into Lin Yun's limbs and lilies, constantly wandering around in the tendons, Lin Yun tightened his mind and operated the Mixed Heaven Recipe to refine the pure aura in the Huanglong Pill.

An hour later, Lin Yun breathed, a white dragon in the wing of his nose erupted out, turned into a round of smoke, and dissipated in the air, Lin Yun opened his eyes, the essence of his eyes flashed, the corners of his mouth smiled slightly, and muttered, "I didn't expect that a low-grade Huanglong Dan would actually be better than half a month of penance for myself, if I look like this, it won't be long before I will break through to the second layer of qi refining, and it will be just around the corner to advance to the middle stage of qi refining."

After refining the Huanglong Pill on a moonlit night, he did not immediately continue to take the Huanglong Pill to cultivate, but after a comfortable day of sleeping, he came to the Elixir Garden.

After Lin Yun came to the elixir garden, after seeing the good trend of the elixir of the elixir, he was overjoyed, and picked all the ripe elixirs and kept them for later use.

The elixir of direct fruit, continue to be sown.

Lin Wan was busy in the Elixir Garden for most of the day.

When his heart moved, he took out the Imperial Spirit Ring, took out the Huanglong Pill, refined the Huanglong Pill to increase his cultivation, and left.

Time inadvertently flows, ten days, in the blink of an eye.

After ten days, Lin Yun took two pills of Huanglong Pill a day to cultivate, and at this time, Lin Yun's cultivation had already reached the critical point of the first level of Qi cultivation and the second level of Qi training.

On this day, Lin Yun planned to break through the first layer of Qi training and advance to the second layer of Qi training.

Lin Wan stuffed a medium-grade Huanglong Pill into his mouth, which Lin Yun used for cultivation before, and it was all a low-grade Huanglong Pill that he had taken.

However, the effect of the medium-grade Huanglongdan is ten times that of the lower-grade Huanglongdan.

The medium-grade Huanglong Pill fell into Lin Yun's mouth, and directly turned into a stream of jin liquid and fell into the abdomen, and a majestic aura under the condensation continued to swim around among the meridians in Lin Yun's body.

Lin Yun only felt that after his dantian was shaken, his own momentum soared, and after reaching a certain height, he stopped moving, and Lin Yun's cultivation naturally advanced to the second level of Qi training.

After Lin Wan advanced to the second level of Qi training, he did not stop the operation of the exercises.

Instead, he continued to stuff a Yellow Dragon Pill into his mouth, and then consolidated his own cultivation.

A day later, after Lin Yun's cultivation was stabilized, his eyes opened, his eyes flashed, and the corners of his mouth smiled.

I finally advanced to the second level of qi training.

However, after Lin Wan advanced to the second level of Qi training.

Instead of taking two Huanglongdan a day like before, but taking one Huanglongdan a day, Lin Yun felt that taking so much Huanglongdan was already an erysipelas and drug resistance to Huanglongdan, and the effect was much worse than before.

Lin Wan spent four hours a day cultivating, and the rest of the time went into the medicine garden of the Imperial Spirit Ring to pick ripe elixirs.

The rest of the time is to delve into the alchemy in the elixir encyclopedia.

Lin Yun found that in the encyclopedia of elixirs, in addition to several elixirs that increase cultivation for qi cultivators, there are also several elixirs such as the return elixir, the detoxification pill, the breaking elixir, and the elimination elixir.

Hui Ling Dan is used to restore the aura of the monk, just right, refining the elixir of the Hui Ling Pill, there are all the spiritual rings, Lin Wan refined seven or eight furnaces out, and got thirty-four Hui Ling Pills.

The detoxification pill is used to detoxify all kinds of poisons, and it is also just in the spirit ring, the elixir is complete, Lin Wan refines two furnaces, and gets twelve detoxification pills.

As for the elixir is used to recover injuries, taking the elixir can dissipate the spiritual energy of the monk's whole body for an hour, and the two elixirs here are each lacking two elixirs, and Lin Wan has not refined them.

On the contrary, on the one hand, Lin Yun continued to study the alchemy technique and pondered how to refine it, but Lin Yun's alchemy technique improved by leaps and bounds.
