Pharmaceuticals and alchemy are the same, and they are also graded in terms of refining techniques. They are divided into four grades, A, B, C, D, and the grades of the medicine refined are also these four grades. Class A is the best, and Class D is the last.

Each grade is also divided into three levels, so that the quality of the medicine can be divided in great detail.

Most of the pharmaceutical methods owned by Lin Tian are first-class, and he lived hundreds of thousands of years ago, so he should have mastered many pharmaceutical methods.

It is said that above the first rank, there are king-level pharmaceutical techniques and alchemy methods, but even if Lin Tian has lived for so many years, such a medicine is rarely seen.

What Lin Tian was going to refine was the most basic Pei Yuan Elixir, and the effect produced by Pei Yuan Dan was the same. It's just that the efficacy is much worse, and of course, Lin Tian doesn't have the conditions to refine the pill now.

Now Lin Tian could only use advanced refining techniques to improve the medicinal effect of Peiyuan Elixir as much as possible. In this way, it can make up for the lack of being able to do alchemy.

But even so, the most important thing is the elixir. Only when you find enough elixir can you refine the Peiyuan Elixir.

As the most basic elixir, Peiyuan Elixir does not require many materials, only three elixirs are needed, and then a certain method can be successfully refined.

These three elixirs are the thousand-year-old spirit ginseng, the nine-leaf Xuanwei grass and the hemp dragon flame flower.

These three elixirs were very common hundreds of thousands of years ago, and as long as they had a simple refining method, they could be successfully refined.

There were no these three elixirs among the dozen or so elixirs taken out of the cave before, and now Lin Tian could only go to the elixir garden to explore, there were hundreds of herbs in the elixir garden, and it was not difficult to find these three elixirs.

Just do it, and at that moment, Lin Tian walked towards the Elixir Garden.

Now that the one-tailed spirit ape has been driven away by Lin Tian, according to the average number of elixirs it steals from the elixir garden every day, plus the number of Zhao Dazhong's private pockets, the current Lin Tian can pick nearly a hundred elixirs in the elixir garden on average every month.

When he arrived at the Elixir Garden, after some searching, Lin Tian couldn't help but be a little disappointed.

It's not that these three elixirs don't exist, but that the year is too short.

The thousand-year-old spirit ginseng Lin Tian didn't see it at all, and only found dozens of hundred-year-old spirit ginseng, and most of the rest were decades old.

And the nine-leaf Xuanwei grass Lin Tian didn't see it, only saw some three-leaf Xuanwei grass. And the vintage of the Ma Long Yanhua is not enough, it is far from what he wants.

The peiyuan agent in Lin Tian's heart can directly break through to the third layer of the condensation stage after taking one dose. And at the moment, the elixir that is not enough for these years, I don't know what kind of elixir they will refine.

After thinking about it, this is the only way it can be. If this Tianxuan Sect could have so many high-grade elixirs, it wouldn't be so depressed now. Pick some high-grade elixirs casually to refine some pills, and I'm afraid that there will be many masters in the Tianxuan Sect.

At present, the elixir that was not enough for these years could only be used improvised, and Lin Tian had no other way.

At that moment, Lin Tian prepared these three elixirs, and then he transported the faint aura and probed these aura into the elixir, changing some of the structures in the elixir. Then he used a special technique to start refining the cultivation elixir.

Refining potions is not as complicated as alchemy, but it doesn't take a short time. In addition, the current Lin Tian has only just awakened the spirit acupoint, and he does not have any powerful spiritual power to refine it at one time, so he can only do it in stages. After the aura in the spirit cave was exhausted, Lin Tian needed a period of time to recover the aura before he could continue refining.

It took a whole afternoon for Lin Tiancai to refine this Peiyuan Elixir.

Ding and so on!

Looking at the potion in his hand, Lin Tian wiped the sweat on his head. This was the first time in his life that he had refined a potion, and it was good to be able to succeed.

Although the grade of the elixir was not high, with Lin Tian's first-class technique, he still refined a first-class potion of the D rank, although the grade was not high, but at least it was stronger than the second- and third-grade of the Ding grade.

If he was given some good materials, Lin Tian believed that he would even be able to refine a C-grade elixir. It's just that his aura is not enough now, and he doesn't have so much aura to refine higher-grade elixirs.

Even so, it's enough. After the Peiyuan Elixir was refined, Lin Tian couldn't wait to take it.

A warm current entered the mouth and spread all the way throughout the body. Lin Tian hurriedly controlled this aura and let it pour in the direction of the Taichong Acupoint.

The Taichong acupoint slowly formed a faint whirlpool, constantly absorbing this aura. With continuous absorption, Lin Tian's Taichong acupoint was gradually getting bigger.

An hour later, this aura was finally absorbed by Lin Tian's Taichong Acupoint. Next, as soon as Lin Tian's mind moved, Taichong **** sent out an aura and rushed directly towards an acupuncture point next to it.

The process of impacting the acupuncture points was painful, even for Lin Tian. Beads of sweat rolled down Lin Tian's head, and even his body trembled slightly.

Once, twice, three times......

Lin Tian controlled the aura and constantly impacted that acupuncture point. The pain is gradually intensified.

"I can't fail, I want to be strong!"

While enduring the pain, Lin Tian shouted loudly in his heart.

Even if people awaken the spirit cave, it doesn't mean that they have become strong. Only by constantly penetrating the acupuncture points can we become stronger step by step. If not, you can only stop.

"Boom!"

I don't know how long it took, there was a loud bang in Lin Tian's mind, and the acupuncture point next to the Taichong acupoint was finally penetrated.

"It worked!"

Feeling that the acupuncture point was finally penetrated, the aura naturally flowed towards that acupuncture point along the Taichong acupoint, and a line was formed between the two acupuncture points.

Although the second acupuncture point was penetrated, Lin Tian did not stop. Instead, he used his aura to rush towards the next acupuncture point.

There was a lot of aura obtained through the Peiyuan Elixir, and Lin Tian wanted to see what kind of effect the Peiyuan Elixir he made could achieve.

Time passed little by little, the sky outside the window gradually darkened, and Lin Tian in the wooden house was still carrying out the impact of acupuncture points.

One, two, three......

With Lin Tian's continuous efforts, one by one the acupuncture points were penetrated by him.

"Boom!"

The sky outside gradually brightened, and at this time, a loud noise came from Lin Tian's mind again.

It worked!

After a night of impact, Lin Tian finally completed the nine acupuncture points, forming a spiritual vein between these nine acupuncture points.

Condensation layer 1!

With that loud noise, Lin Tian knew that his current cultivation had reached the level of condensation.

Feeling the condition in his lower body, a smile appeared on Lin Tian's face.
