Lin Luo didn't know what Han Li was thinking after seeing him.

At this time, he was in the House of Earth Fire and looked at the contents of the two jade slips in his hand.

The first volume is the various gains and losses of his last alchemy and the tips he asked the old man surnamed Ma for alchemy.

The second volume is the alchemy experience and pill recipes that the Lin family has accumulated over the years, and there are no more than five people in the entire Lin family who are qualified to view, and Lin Luo is one of them.

There are two kinds of pills he wants to refine this time, the Yuan Ling Pill, which contains qi and disperses.

The Gu Dan Pill obtained by the ancestors of the Yuan Ling Dan Lin family, not because of the lack of elixir, has only appeared a few times since it was obtained, and its effect is that it can make the monks above the tenth layer of Qi refining improve by one level without any side effects.

After convincing the use of the Yuan Ling Pill, Lin Luo could easily go from the twelfth layer of qi refining to the thirteenth layer of qi refining, which can be imagined how precious it is.

If it weren't for the fact that the Frog had emptied all the bloody forbidden lands this time, he would not have been able to scrape together all the main medicinal materials he needed, a six-hundred-year-old elixir.

And the Yun Qi Dispersion was equivalent to the enhanced version of the Yellow Dragon Pill in Han Li's hand, which could increase the mana of the cultivators above the tenth layer of Qi refining.

The entire Lin family only had two bottles, and when he entered the Yellow Maple Valley, he obtained five Yun Qi Scatters, so that he could cultivate to the twelfth level of Qi refining.

And with these two pills, with his qualifications, he grasped the cultivation to the peak of the thirteenth layer of qi refining before the blood-colored forbidden land, plus three top-level magic weapons and ninety-eight K. He had absolute certainty that he would kill "Senior Brother Lu", and then find a safe place to hide until the trial was over.

At that time, you only need to prepare in advance, and twenty elixirs can get two Tsukidan.

For most of the day, Lin Luo made sure that he had memorized all the precautions before putting the jade slip back into the storage bag, and then took out a fiery red Dan furnace with a little starlight.

This Dan Furnace was one of the two top-level magic weapons on his body, called the Silver Fire Furnace.

In addition to being able to refine pills, because of the addition of silver essence and iron essence, the defense is still extremely good. Within 100 meters, they were swept by the ninety-eight K for a while, and they were not injured at all, which was one of their Lin family's ancestral magic weapons.

After placing the furnace at the mouth of the fire, sit cross-legged and close your eyes to breathe.

He wasn't Han Li who had countless elixirs to waste, he had to make sure that he couldn't make more than five mistakes at a time.

Otherwise, the final pill will not be enough.

And this sitting is a day, a day later, Lin Luo opened his eyes, his dark eyes were shining, at this time he was in an unprecedentedly good state, whether it was the true yuan mana in the dantian, or the divine sense was extremely full.

Then, as soon as he patted the storage bag, more than a dozen jade cups were neatly placed on both sides of his side.

It was full of medicinal powders that he had prepared, most of which came from the Blood-Colored Forbidden Land, and only a small number of auxiliary medicines were elixirs grown in the Hundred Medicine Garden.

After glancing at the jade and making sure that the number was correct, he cast a spell to introduce the earth fire into the Dan furnace.

Just the tea kung fu dan furnace is like a scorching sun, blazing people.

Feeling that the fire was coming, Lin Luo's face condensed slightly, and then he pointed to the lid of the Dan furnace, and then, he saw the lid lifted, and then he picked up the nearest jade jar, poured the medicinal powder in it and roasted it.

After about three minutes, a faint but refreshing medicinal fragrance diffused from the Dan furnace, hearing this, Lin Luo did not dare to delay, and picked up a jade and poured its Chinese medicine powder into the Dan furnace, and then roasted it again to fuse the two medicinal powders.

As time passed, the medicinal fragrance emitted from the Dan furnace became more and more intense, which made people feel refreshed when they smelled it.

But Lin Luo knew very well that it was still very early for Cheng Dan at this time, and at the very least, he had to use a more violent earth fire to carry out instantaneous condensation pills, so that the pill could be formed.

For the vast majority of alchemists, this step is basically a matter of luck.

If you are lucky, you will succeed once, and if you are unlucky, you will not succeed even if you get it hundreds of times.

Thinking of this, Lin Luo took out a machine and put it aside, and the machine read: Infrared thermometer.

That's right, it's the infrared thermometer, something that the frog brought with him on his last trip.

It was precisely because of this thing that he decided to refine the pill, so that he could determine the temperature of the fire when he became a pill, as long as he knew the instantaneous temperature of the pill, then the chance of success should be much higher.

It is difficult to determine the specific temperature with the divine mind sensing alone, and you can only have an approximation.

The Qi Refining Cultivator's Divine Thoughts were similar to radars, and they could not measure specific temperatures.

After placing the thermometer, Lin Luo re-made it, and then used his divine thoughts to sense the changes inside the Dan furnace, and then slowly adjusted the heat.

Then, with a muffled sound, Lin Luo stopped the ground fire, opened the Dan furnace to take out the waste residue in it, cleaned it up, closed his eyes and began to recall the various changes that had occurred in the Dan furnace before the alchemy failed.

After identifying the error point, he opened his eyes and checked the temperature change at that time before starting again and putting the Yuchen Chinese medicine powder into it.

……

In this way, Lin Luo stayed in the Earth Fire House for a whole month, and only after all the medicinal powders he brought were used up did he end this alchemy.

His guess was correct, with the thermometer, the success rate of his alchemy increased by more than half.

When the state is at its best, five or six furnaces in a row can be successful. As long as the temperature of the instantaneous condensation is determined, the success rate is greatly improved, and as long as there is no big problem, it can basically become a pill.

Therefore, he can be said to have gained a lot this time, not only has there been obvious progress in alchemy, but also refined a large number of pills.

There were five bottles of the Yuan Ling Pill alone, and each bottle had twenty or thirty pills.

As for Yun Qi Dispersion, there are even more, and it is also his main refining pill this time, a full twenty bottles, each bottle of thirty pills, a total of six hundred.

To put it bluntly, if these pills are given to the Lin family, they will definitely be able to make the Lin family appear more than a dozen Qi refining twelve or thirteen level monks in a short period of time, if there are enough foundation building pills, the Lin family will be able to appear three or five foundation building monks, and it will definitely be able to become the cultivation family second only to the three major families.

However, it's not that it doesn't work now, it's not that I don't believe my father, but if the Lin family's strength skyrockets in a short period of time, fools will know that there is a problem, and it will not be good to attract the attention of Huang Fenggu and other families at that time.

Therefore, these pills must at least wait for him to build a foundation and have a certain amount of self-protection before giving them to the Lin family.

A foundation-building monk in the Yellow Maple Valley and a Qi refining stage disciple are not the same concept at all, and they are enough to deter many people.

And he only needs to cultivate step by step.

You must know that there are still a lot of elixirs in the blood-colored forbidden land, and with his current alchemy skills, it is enough to support his cultivation to the late stage of foundation building, and even before the invasion of the demon path, it is possible to advance to the late stage of the foundation building of the Dao, and then find a way to fake his death and leave Tiannan.

Of course, this is a choice made only as a last resort.
