In the cave, Han Chen sat quietly, his right arm stretched forward, his palm pressed on the black fire mouth of the Black Emperor Ding, his eyes slightly closed, his face calm, and his breath was long.

There are more than two hundred kinds of medicinal herbs, totaling nearly 10,000 plants, which is indeed a lot, but before, it took a day and a night for Han Chen to refine nearly 8,000 plants.

Subsequently, after the topographic map of the Red Desolate Secret Realm appeared, although it took some time, more than a thousand medicinal herbs only took an hour and a half, and they were completely exhausted.

I saw that at this time, the ground around Han Chen was smooth and clean, except for a few pieces of gravel of different sizes, there was nothing else, not even a piece of residual leaf of medicinal herbs.

Although it was said that after the practice of more than 8,000 medicinal herbs in the past, Han Chen's control over the essence of refining medicinal power had become much more and more proficient, and his hand feel, flame control, feeling, and so on had also been greatly enhanced.

But it has only reached the point where it takes one attempt to refine and a second time to successfully refine the essence of medicinal power.

For an ordinary alchemist, Han Chen's level was already extremely amazing, after all, even some fifth- and sixth-grade alchemists didn't dare to say that they didn't need any attempt to successfully refine the essence of medicinal power at one time.

Except, of course, some gifted geniuses.

According to reason, even those fifth- and sixth-grade alchemists didn't dare to guarantee things, Han Chen, who was not even a second-grade alchemist, and his soul power was only at the peak of a first-grade alchemist, he actually wanted to reach the point where he was not allowed to try, and he could successfully refine medicinal materials and refine the essence of medicinal power at one time. Isn't it crazy?

Is Han Chen really crazy? Naturally not.

The reason why Han Chen did this was also because he had a certain degree of certainty.

First of all, his soul was originally more than ten times stronger than ordinary people, and although he was only at the peak level of a first-grade alchemist at this time, it was only not enough in terms of quantity, and in terms of the purity of his soul power, he was actually not inferior to a second-grade mid-level alchemist.

However, if you want to advance to the second-grade alchemist level, the most important thing is the powerful level of soul power. If the soul power is not strong enough, it will not be able to support the refining of the second-grade pill at all, and the refining will be halfway through. Soul power is depleted. In the end, it can be the result of destroying Dan.

This was also the reason why the purity of Han Chen's soul power had clearly reached the level of a second-grade mid-rank alchemist, but he was unable to practice the method of refining second-grade pills.

In this way, Han Chen's soul power is so pure, isn't it useless?

Naturally not.

Alchemist whether it is alchemy. Or promotion promotion. What is valued is indeed the powerful level of soul power.

But the chances of success in alchemy. As well as the success rate of promotion and promotion, in fact, the most important thing is to look at the purity of the soul power.

The more refined the soul power. The more you can control it, the more handy it will be. The more condensed it is, the more it is used.

Alchemy is a delicate job, whether it is refining the essence of medicinal materials, or quenching pills and melting pills, there are high requirements for the purity of soul power.

Therefore, many alchemists would rather suppress the increase speed of their own soul power, spend more time, find some genius treasures, or condense their own soul power by themselves, rather than break through the ranks too early.

Because, the breakthrough of the promotion level means that the strength of the soul power increases, just like a small pond, it slowly turns into a big lake.

Originally, the silt in the small pond had not been cleaned up, but now it has become a large lake, and if you want to clean up the silt in it, the difficulty is not one or two times, but a hundredfold and a thousand times.

Han Chen had already learned about this from Guiguzi.

The purity of soul power! This is one of Han Chen's dependencies.

As for the second dependence, it is simpler.

First of all, the two hundred kinds of medicinal materials he refined, and nearly 10,000 medicinal materials, were just some medicinal materials needed to refine the second and third grade pills, not genius treasures, just some middle and high-level medicinal materials.

Whether it is refining or refining the essence of medicinal power, the difficulty is not too great, as long as you try a few times, you can basically refine the essence of medicinal power smoothly, the difference is only whether the essence of medicinal power is refined or not.

With the purity of Han Chen's soul power, it was not impossible to reach the point where he could successfully refine the essence of medicinal power in one go without trying through the practice of nearly 10,000 medicinal herbs.

And as long as you can find the best hot spot, the purity of the essence of the medicinal power extracted does not need to be considered at all.

The value of the saliva fruit is indeed very precious, after all, things that can improve the qualifications and talents of martial artists are rare.

It is also worthy of the four words genius Dibao.

It's just that genius earth treasures are also divided into three, six, nine and so on.

The Jiao Saliva Fruit is indeed a genius earth treasure, but the probability of improving the qualification talent is too low, so even if the Jiao Saliva Fruit is ranked among the genius earth treasures, it is only worthy of it.

Don't say that the spiritual product is a genius and a treasure, and even ordinary products can't reach it.

In the Genius Treasure, there are six grades.

There are six grades of mortal, spirit, king, emperor, emperor and heaven. With the lowest grade and the highest grade, each grade has four levels: lower, intermediate, high, and best, and a subdivision is carried out.

This saliva fruit is only among the genius treasures, not the product.

After practicing nearly 10,000 medicinal herbs, once Han Chen was able to reach the point where he could successfully refine them without trying, it meant that Han Chen could basically refine the middle and high-level medicinal materials once.

In this way, if he wanted to successfully refine the two salivary fruits, Han Chen could be regarded as having some certainty, but it was just that.

Although the Jiao Fruit is only worthy of being listed as a genius treasure and has not been included in the product, it is still among them after all, and there is still a gap between it and the middle and high-level medicinal materials.

To be able to refine successfully, Han Chen himself didn't know the Dao, he could only look at the Mandate of Heaven

Han Chen, who was sitting in front of the Black Emperor Ding, did not move for a long time, and his breathing had gradually become inaudible, turning into a statue.

If it weren't for the slight heaving of his chest for a long time, I am afraid that he would have lost his breath. Died.

The pale cyan flame, like a fairy, rises and jumps from time to time in the tripod, and the firelight is projected through the holes in the lid of the tripod, forming a light and shadow, which is very beautiful.

At a certain moment, Han Chen's eyelids suddenly trembled, and his eyes immediately opened, and a fine light flashed in his dark eyes.

The right hand pressed on the Black Emperor Ding's fire mouth and did not move. The fingers of his left hand in the air flicked rapidly. With the flicking of his fingers, he saw the pale cyan flames in the ding fluctuate violently.

As the flames fluctuated, streams of astonishing heat emitted from each other, and there was a pause. I saw that the lines on the inner wall of the tripod were quickly revealed. Just two breaths are clearly visible. Then a faint light emanated.

For these line marks, Han Chen didn't care, all his mind. They all fell on the fiery red liquid in the flames in the Ding.

That was the essence of the medicinal power in the Tian Yuan Fruit. Tian Yuan Fruit is one of the main medicinal materials for refining Huangji Dan.

Huangji Dan is a five-grade pill, and the effect is the same as that of the Huiqi Pill, but the Huiqi Pill can only play a role in the three realms of Sword Guard, Sword Master, and Sword Soldier, and generally speaking, when it comes to the Sword Soldier Realm, the side effects of the Huiqi Pill are already very large, and if you don't want to, you won't take it.

Once the swordsman breaks through and enters the Sword Spirit Realm, he can take the Yuan Spirit Pill.

The Yuan Ling Pill is a four-grade pill, and its effect is the same as that of the Hui Qi Pill, but the cultivation realm of taking the Yuan Ling Pill is at least the Sword Spirit Realm.

And the Huangji Dan, it is even more on top of the Hui Qi Pill and the Yuan Ling Pill. It is the elixir taken by the Sword Emperor Realm.

As one of the refining medicinal materials of the Huangji Dan, the grade of Tianyuan Fruit is naturally extraordinary.

It is a high-level mid-quality medicinal material, and it is naturally difficult to refine.

Just refining the essence of the medicinal power in it, Han Chen had consumed nearly two hours, and he was still in the Samadhi True Fire of the Triple Heavenly Queen.

If it was before the promotion, Han Chen estimated that even if he refined it for a day, he might not be able to completely refine it.

Fortunately, after more than two hours of refining, the essence of the medicinal power in it has not only been refined, but also the impurities in it have also been refined and removed.

The pale cyan flames in the ding were like dragons, constantly churning and crashing.

After refining it again with the high temperature, the index middle finger of Han Chen's left hand suddenly rose together, and the void led towards the sky.

"Get up!" he snorted.

The next moment, the fiery red liquid in the pale cyan flame suddenly leaped up, and with a 'boom', it leaped away from the hole in the lid, and at this time, Han Chen's left hand had already taken out an empty white jade bottle and directly inserted it into the bottle.

Call!

It was only at this point that Han Chen finally let out a long breath.

As soon as his mind moved, the pale cyan flame in the Black Emperor Ding was like a tide, surging suddenly, and finally turned into a palm-sized flame, and then the flame disappeared at the bottom of the Ding and returned from the fire mouth.

After that, it was directly taken into the body by Han Chen's palm.

After putting the Samadhi True Fire into the upper dantian on his eyebrows, Han Chen immediately didn't care about anything else, even the essence of medicinal power that had just been refined didn't bother to glance at it, and quickly plugged the lid and put it aside.

Immediately, he put his hands on his chest, closed his eyes, and his mind sank into his body, and his mind moved, and the Cold Snow Sword Technique quickly worked in his body.

In an instant, Han Chen entered the cultivation.

Time passed quickly, and Han Chen's cultivation this time was not so fast, and it was only after the time of the three incense sticks that he withdrew from his cultivation.

Call!

Exhaling a breath of turbidity, Han Chen only felt refreshed, and his whole body was extremely relaxed.

"Three-star swordsman mid-stage!" his mind swept through his body, Han Chen was slightly stunned, and then couldn't help but smile bitterly and shook his head.

He didn't expect that just the practice of refining medicinal materials and refining the essence of medicinal power would also be able to raise his cultivation realm to a small level.

If the cultivation realm was improved, if it was placed a few days ago, he would definitely be extremely happy, after all, after the martial artist entered the sword soldier realm, his cultivation speed would be slower than that of the sword master and sword guard realm.

Every improvement takes a lot of effort and a lot of time.

But after understanding his own situation, Han Chen could only smile bitterly. (To be continued......)
