The so-called alchemy, to put it bluntly, is to use spiritual grass or other substances to smelt medicinal stones in the furnace fire.

After resting in the cave for one night and exercising for two hours in the morning, Zhang Tianzong took out the Danding in the Qiankun bag and began to prepare for the alchemy.

As for the Danding, it is a vessel used for alchemy, which is composed of two parts: the top is the Ding, and the bottom is the furnace.

Among them, the tripod is used for purification and condensation, and the furnace is the furnace fire and is used to heat the tripod.

The quality of Danding can directly affect the success rate of Dan Yao.

Fortunately, Zhang Tianzong has a good father. Although the Danding he used was not the best in the Tianxiao Continent, its quality was also ranked in the top ten.

Alchemy is divided into four steps, one is to prepare the required materials, the second is purification, the third is fusion, and the fourth is to condense the pill.

Zhang Tianzong planned to refine the second-grade top-grade Wind Catching Pill first, and the spirit grass and pill bottle he needed had already been taken out by him and placed on the ground in an orderly manner.

got up and came to the cave, and after making sure that no one was disturbing, Zhang Tianzong returned to Danding and sat down.

When his mood was completely calm, Zhang Tianzong first added fuel to the furnace, lit it and heated the ding.

Each level of pill in the Tianxiao Continent has different requirements for temperature.

If the temperature in the ding is high, the essence of the spirit grass will all volatilize, and not a drop will be left.

If the temperature does not meet the requirements, the extracted liquid essence will contain impurities, which will directly affect the final quality of the elixir.

In fact, the reason why each level of elixir is divided into four levels: top-grade, upper-grade, middle-grade and lower-grade, in Zhang Tianzong's view, is because there are the least ineffective substances in the top-grade pill and the most low-grade.

After thinking about it for a while, the temperature in the ding initially met Zhang Tianzong's requirements, and the next thing was to keep this temperature pure.

According to a certain proportion, charcoal and black lazuli were added to the furnace fire, and after waiting for another three minutes, Zhang Tianzong began to put the same kind of spirit grass into the ding.

To put it simply, purification is to extract the essence part of the spirit grass, at the right temperature, the debris contained in the spirit grass will be evaporated by the high temperature in the ding, and the essence part will be retained into spiritual liquid.

It took about ten minutes for Xu Huacao who was refining the second-level Wind Catching Pill to be refined by Zhang Tian and turned into three vials of spiritual liquid.

Putting the spiritual liquid of Xu Huacao aside, Zhang Tianzong lowered the temperature in the ding slightly, and continued to purify another spiritual grass.

It took about two hours, and the four second-level spirit grasses and nine first-level spirit grasses needed to refine the second-level wind catching pill were all turned into bottles of spiritual liquid.

Standing up and moving his limbs, Zhang Tianzong began to impact the meridians with the heaven and earth aura that was spontaneously absorbed in his body.

After the aura in his body was consumed, Zhang Tianzong checked the surrounding environment and continued the third step of fusion after making sure that no one was disturbing.

As the name suggests, fusion is to fuse the various spiritual liquids that have just been extracted according to the requirements of the Dan Fang in proportion, and then reduce the temperature of the furnace fire, and the spiritual liquid will cool into Dan.

The temperature requirement for fusion is slightly lower, but the amount of various spiritual fluids is quite strict.

If there is one more drop or one drop less of a certain spiritual liquid, it can directly affect the quality of the elixir, and if it is serious, it will directly cause the alchemy to fail.

Taking a deep breath, and when the temperature in the ding reached the requirements, Zhang Tianzong began to add spiritual liquid to the ding.

The first main medicine, followed by the spiritual liquid of various spirit herbs.

Naturally, the order of adding various spiritual fluids must not be confused, otherwise the alchemy will still end in failure.

This time, it only took about three minutes for Zhang Tianzong to add the last spiritual liquid needed by the second-level Wind Catching Pill.

After waiting for about two minutes, Zhang Tianzong removed the tripod from the stove, and then directly lowered the temperature of the tripod with water.

A thick burst of white smoke rose, and Zhang Tian took a deep breath and directly opened the lid.

Succeeded, looking at a crystal clear pill lying quietly at the bottom of the ding, Zhang Tianzhong was overjoyed.

Carefully taking out the pill, Zhang Tianzong had a smile on his face.

The fly in the ointment is that this Wind Catching Pill is only a second-grade mid-grade, and it is still some distance from the best.

But this was Zhang Tianzong's first time refining a second-level wind catching pill, and he was ready to fail before.

can refine it successfully at one time, what is he not satisfied with.

After being happy for a while, Zhang Tianzong ate a little bit at random, and put aside the remaining spiritual liquid of the Wind Catching Pill first.

He was going to refine the second-grade top-grade tonic elixir first, so that if he refined the second-grade wind-catching pill, he would have a certain degree of confidence in refining the best.

An afternoon passed slowly.

Of the fifteen second-level spirit pills, Zhang Tianzong refined twelve spirit pills, and the success rate reached an astonishing eighty percent.

You must know that if the alchemist of the Tianxiao Continent has a success rate of 30 percent, then he can barely keep his capital, and if the success rate reaches 60 percent, he can earn twice as much.

To take the simplest example, the spirit grass required for ten second-level replenishing elixirs is worth a total of forty lower-grade spirit stones, and twenty low-grade spirit stones for fuel, for a total of sixty lower-grade spirit stones.

Then these ten spiritual herbs, if you can refine three second-grade top-grade tonic elixirs, you can return all the spirit stones by buying spiritual grass and fuel, and if you practice five top-grade tonifying elixirs, the extra two are pure profits.

Fifteen parts of spirit grass, Zhang Tianzong only needs to refine four top-grade spirit pills, then he can barely return to his roots.

But he has practiced twelve of them, although only six of these twelve are the best tonic elixirs, and the rest are high-grade and middle-grade, but he has also earned nearly double.

To put it more simply, Zhang Tianzong had spent about ninety lower-grade spirit stones to buy fifteen copies of spirit grass before, but if all the pills he refined were to be sold, he could get about one hundred and eighty lower-grade spirit stones.

Earned ninety low-grade spirit stones, which doesn't seem to be much.

But the miscellaneous disciples of Wuji Sect, the spirit stones they receive from the sect in a year are only ten lower-grade spirit stones.

Not to mention the miscellaneous disciples, they are the disciples of the outer sect of the Wuji Sect, and the spirit stones they receive from the sect in a year are only one hundred lower-grade spirit stones.

If these ninety low-grade spirit stones were exchanged for silver, it would be ninety thousand taels of silver, which many farmers could not earn by planting land for a lifetime.

Of course, in order to refine the second-grade top-grade spirit pill, the spirit grass that Zhang Tianzong had wasted before had added up to more than six thousand lower-grade spirit stones.

It's just that there is a loss, there is a gain, and now that he can successfully refine the second-grade best elixir, the spirit stones he lost before can be earned back in two months at most.

What made Zhang Tianzong happiest was that now that he had successfully refined the second-grade best elixir, then he could try to refine the third-grade elixir next.

As long as he successfully refines the third-grade tonifying elixir, even if it is the lowest-grade low-grade tonifying elixir, then he is a real third-grade alchemist.

Twelve-year-old third-grade alchemist, in the more than 6,000 years of history of the Tianxiao Continent, as far as Zhang Tianzong knows, it seems that there really has never been one!
