Cultivation, I have a world of high martial arts

Condensing the liquid into pills is the most critical step in the alchemy process.

At the same time, it is also the most difficult step.

This step requires the alchemist to have an extremely precise grasp of the temperature and timing.

After the high-temperature flame purifies the pill liquid, the temperature in the pill furnace is quickly lowered to a certain level in a short period of time.

For ordinary alchemists, this is extremely difficult.

But for Lin Chen, who uses instruments to make pills, it is not complicated.

"During the pill condensation stage... the temperature in the pill furnace must drop by about 3,000 degrees."

Lin Chen murmured. He could only roughly determine the temperature range, and the exact temperature still needs to be tried.

So as expected, the first attempt failed.

The entire furnace of foundation-building pills was wasted.

After that, Lin Chen started the second and third attempts.

A total of six failures.

Finally, Lin Chen got an accurate temperature.

It is necessary to reduce the temperature in the pill furnace from 3389 degrees to about 350 degrees within ten seconds.

Until the evening.

The first furnace of foundation-building pills refined by Lin Chen came out!

A round foundation-building pill, wrapped in wood essence, slowly fell into his hands.

Lin Chen sniffed the pill and carefully identified it, and his face suddenly showed a slight joy.

"It's a mid-grade foundation-building pill!"

The steps of refining the pill were completed with instruments, with almost no errors.

It was enough to surpass most alchemists and successfully reach the quality of mid-grade foundation-building pills. Its efficacy was several times better than that of ordinary foundation-building pills.

"However, is the mid-grade foundation-building pill the limit of instrument alchemy?"

Lin Chen thought carefully.

After all, this was his first time to refine a foundation-building pill, and there were still some mistakes just now.

If the temperature can be made more accurate, or other mistakes can be reduced, is it possible to refine a high-grade foundation-building pill?

Do it as soon as you say it.

Lin Chen first called his uncle and aunt and told them that he would not go home tonight.

After that, Lin Chen spent the whole night refining the foundation-building pill.

A cultivator who has perfected Qi refining has a spirit far beyond that of ordinary people.

Even if he refined it all night, Lin Chen's spirit was still very successful.

Until the afternoon of the next day.

Lin Chen snapped his fingers, and six furnaces of foundation-building pills came out at the same time.

Among them, one furnace was useless, and four furnaces were medium-grade foundation-building pills.

There was another furnace...

The mysterious pill pattern on the pill appeared faintly.

This is the top-grade foundation-building pill!

"A total of 23 furnaces of foundation-building pills, 20 furnaces of successful pills."

"Among them, five are low-grade, twelve are medium-grade foundation-building pills... top-grade foundation-building pills, a total of three!"

Lin Chen raised his eyebrows.

This success rate and quality of the pills are amazing!

Han Jihai once told Lin Chen that his success rate in refining foundation-building pills was only 60%.

And more than 90% of them were low-grade foundation-building pills.

The success rate of refining top-grade foundation-building pills is only 1%!

"The instrument refining pills is really like a cheat!"

"Except for the top-grade pills, it is impossible to refine... Compared with ordinary alchemists, it is simply a crushing existence."

Lin Chen packed the five newly-baked pills one by one.

Now, he has 27 foundation-building pills in his hand.

Among them, there are six top-grade foundation-building pills!

"This time, I will definitely be able to build a perfect foundation!"

Lin Chen was very happy. A perfect foundation means that his future path will be smoother and he can go further.

"My cultivation is only one step away from the perfection of Qi Refining."

"I will try to complete the foundation building in the next few days..."

Lin Chen thought so.

The movement of breaking through the foundation building is not small.

If he completes the breakthrough in the world of immortal cultivation, it will inevitably attract the attention of others.

But breaking through on Blue Star is extremely safe, and it can perfectly cover up the movement of his breakthrough.

In the next two days, Lin Chen put more attention on Qi Refining practice.

He practiced for more than eight hours every day, and dozens of spirit stones turned into powder.

Under such a practice that did not care about resources, Lin Chen finally cultivated the Qi Refining Chapter to perfection.

At the same time, Lin Chen's cultivation also reached the perfection of Qi Refining.

After reaching the perfection of Qi Refining, Lin Chen did not break through immediately.

Instead, calm down and adjust your own state.

Foundation building is not something that can be completed in an instant.

According to what Lin Chen knows, it may take a whole day to break through the foundation building, and constantly attack the bottleneck of foundation building.

Therefore, it is necessary to ensure that one's own spirit is in the most perfect state.

...

The fifth day of Lin Chen's return to Blue Star.

Under the escort of Li Nian, he came to the martial arts palace again.

Here, there is a safe house built specifically for him.

"Brother Li, my safety will be handed over to you from now on..."

Lin Chen stood in front of the room and said to Li Nian.

Involving business, Li Nian nodded meticulously:

"Don't worry, no one can disturb you in the next day, I said!"

Lin Chen was relieved after hearing this, and entered the safe house.

The house is full of spiritual energy, even comparable to Danfeng.

Here, there is a miniature spirit gathering array, only a few feet in radius.

It is Lin Chen's special preparation for breaking through the foundation building period.

Coming to the center of the miniature spirit gathering array, Lin Chen waved his hand.

Hundreds of spirit stones were scattered around his body.

Afterwards, Lin Chen sat cross-legged, constantly absorbing spiritual energy from the spirit stones and taking it into his own Dantian.

The Dantian in the Qi Refining Stage has a limited capacity.

If it only takes in but not out, the spiritual energy will inevitably overflow.

However, the spiritual energy taken into the body will continuously flush the Dantian and purify the spiritual energy.

This is the first step of building the foundation, the purification of the true essence.

As the surrounding spiritual stones turned into powder one by one, the true essence and mana in Lin Chen's Dantian became more and more pure.

Until, several hours later.

When Lin Chen could no longer increase his mana, and his true essence began to leak out.

Then the second stage of building the foundation was officially opened.

The true essence solidified.

Lin Chen took the first top-grade foundation-building pill.

As the medicinal effect of the foundation-building pill was absorbed by the body, it was like turning on an accelerator.

The true essence and spiritual energy in Lin Chen's Dantian began to accumulate and solidify.

Originally, the spiritual energy in the Dantian was reduced to occupy only one-third of the space in the Dantian.

After that, Lin Chen continued to absorb spiritual energy.

Until, a solid existence like a Dantai appeared in the Dantian.

This is the foundation-building Dantai.

This Dantai is integrated, and the spiritual energy overflows on the Dantai.

The true essence and mana contained in the Dantai alone is more than twice that of Lin Chen's perfect Qi training.

When the Dantai solidifies, the foundation is established.

At this moment, as long as Lin Chen is willing, he can complete the foundation in an instant.

But the low-grade foundation is not what he wants.

So, Lin Chen took the second high-grade foundation pill.

As the effect of the foundation pill continued, Lin Chen increased the speed of absorbing spiritual energy.

The spiritual energy entered the body, solidified, and turned into part of the Dantai.

The originally blurry Dantai became clearer and clearer.

The third, fifth, and tenth foundation pills...

The sun gradually moved westward.

In the safe house, the ground was covered with layers of spiritual stone powder.

And Lin Chen also reached the critical moment of foundation building.

Under the introspection of the soul, the foundation Dantai in the Dantian was like a layer of silver.

At this moment, Lin Chen has achieved the high-grade foundation.

And in the silver, a little bit of gold can be vaguely seen.

Lin Chen took another medium-grade foundation pill.

As the spiritual energy continued to solidify, the details of the foundation Dantai became clearer and more vivid.

At the same time, the faint golden color became more and more dazzling.

Five, ten...

Another ten middle-grade foundation-building pills entered his stomach.

Until the next morning, the first ray of sunlight fell on Lin Chen.

Looking inward with his soul, it was not only the sunlight that was golden...

It was also the foundation-building pill platform in his dantian.

So far, the perfect foundation has been built!

Lin Chen slowly opened his eyes, and the leaked true energy was constantly restrained.

With a smile on his face.

"Finally, the perfect foundation... has been achieved!"
