In the cave, Han Chen sat quietly in the center, and on the ground around him, all kinds of medicinal herbs were neatly displayed.

There are so many herbs that they completely occupy the not very large ground in this cave.

Each herb has its own unique medicinal fragrance, at this time, so many medicinal materials are placed together, the medicinal fragrance is diffused in the air, and the fusion is actually formed into a rich medicinal fragrance.

However, Han Chen didn't care too much about this, because all his thoughts at this time were condensed in the Black Emperor Ding, which was being wrapped in pale cyan flames and burned and tempered honeysuckle.

Honeysuckle is not a rare medicinal material, but it is not ordinary, Han Chen also found it in a small valley in a mountain forest a while ago, and picked it easily, the number is not much, only more than forty plants.

In the Black Emperor Ding, the pale cyan flames continued to sway and jump, and under the control of Han Chen's soul power, the temperature of the flames slowly and evenly increased.

As the temperature of the flame rose to a certain level again, a faint trace appeared on the inner wall of the Black Emperor Ding again, these traces were connected, like lines, but they were too blurry, and the time that appeared this time was shorter than the last time, and it was only less than a third of the time, and it disappeared directly.

The time was too short, and Han Chen's mind was all condensed on the honeysuckle in the flames, and it was impossible to catch and find it.

Just because Han Chen can't find it doesn't mean that others can't find it.

"What is that?" In the sea of knowledge in Han Chen's eyebrows, Guiguzi frowned slightly. said softly: "Although the time of appearance is very short, and it is very vague, it can still be seen that the blurred lines, composed of them, should be a map." ”

Guiguzi has always been in Han Chen's mind, this time Han Chen refined the saliva fruit, he naturally would not ignore it, but he didn't make a sound to disturb.

Because, he felt that Han Chen had been able to leave from under his wing. Soar alone.

Day. When he first entered the 100,000 mountains, he faced a fierce pursuit. On the periphery of the 100,000 mountains, absorbing the spiritual energy of fire, earth, and wood, the four stars of Samadhi True Fire are perfect. Attacked and killed Yan Liuduo. Go to the Blood Python Golden Jiao's lair. On the way, he killed Zhao Quan and others. Until finally won the saliva fruit. Kill the Blood Python Golden Jiao.

In each of these incidents, Han Chen did not rely on Guiguzi's strength.

This is a good start, Guiguzi wants to keep Han Chen going.

Although Han Chen did not refine the Jiao Fruit now. It is just to use honeysuckle and many other medicinal materials to practice. But Guiguzi is still very serious observation.

Quenching medicinal materials and extracting the essence of medicinal power can be said to be the most basic and important step in the first art of alchemy, because no matter what kind of pill is refined, even if it is a nine-grade pill, it is also necessary to extract the essence of medicinal power to start refining.

Therefore, from this step, it can be clearly seen whether the foundation of an alchemist is solid.

And because of this, the appearance of the lines on the inner wall of the Black Emperor Ding was discovered by him.

"Although Zhilu Dao should be a certain map, the line traces are too vague, even if they are detected with the power of the Yuan Shen, they cannot be seen at all, and the time that appears is too short. Guiguzi secretly said in his heart: "Wait and see!"

In this way, Guiguzi fell silent again, and Han Chen's sea of knowledge fell into a calm. However, in this calm, an incomparably powerful soul power surged out, completely filling the Black Emperor Ding, and all the changes in it were completely incorporated into his own perception.

And in this regard, Han Chen did not have the slightest feeling at this time.

If Han Chen knew the truth, he would definitely be shocked.

If a person's soul power is within the range of another person's soul power, it will definitely be noticed. And like Guiguzi, the soul power poured into the Black Emperor Ding unscrupulously, and it was completely enveloped in all directions, but Han Chen didn't even have the slightest feeling, not even the slightest sense of stagnation when he urged the soul power.

There is only one way to do this, and that is that there is a huge gap between the two, as if heaven and earth are there.

It's like a martial artist who has learned martial arts and cultivated to the extreme, just like an ordinary old man with dizzy eyes.

The martial artist used his body martial arts, the speed was like lightning, and he was so fast that even if he dangled in front of the old man many times, the old man couldn't find it at all.

At this time, Han Chen's soul power was that of this ordinary old man with dizzy eyes. And Guiguzi is that warrior.

"Is this here? No, it should be a little better!" All his thoughts were condensed, carefully feeling the changes in the honeysuckle in the pale cyan flames, and then slowly looking for the best hot spot according to the changes.

"This is it!" When the temperature rose again, Han Chen's heart jumped suddenly, and he hurriedly used his soul power to control the temperature of the flame in an instant.

After finding the best hot spot, Han Chen didn't need to work anymore, kept the temperature unchanged, and slowly refined.

After a while, Han Chen's heart moved, he put away the pale cyan flame, and then collected the extracted medicinal essence with a jade bottle.

Glancing at the pale golden liquid in the bottle, Han Chen immediately corked the bottle and put it aside, ignoring it again.

"Although I succeeded in finding the best hot spot of honeysuckle and perfectly extracted the essence of medicinal power, I had refined two honeysuckle plants before, and it was not until the third strain that I succeeded in finding its best hot spot!" Han Chen thought to himself in his heart: "In terms of rarity, honeysuckle is far from being comparable to the saliva fruit, and correspondingly, the difficulty of refining between the two is even more different!"

"If you want to refine the saliva fruit, you can't make any mistakes. ”

"You must elevate the feel and feeling to the peak and limit!" exhaled lightly, Han Chen's eyes froze, and he said secretly.

I have to say that if you want to accomplish this, it can be described as a great challenge for Han Chen.

Because, even those alchemists who have reached the sixth- and seventh-grade levels dare not say that they can be completely sure that they can directly find the hot spot of a medicinal herb that has never been tried and refined, and extract it perfectly.

If Han Chen really did this, it would mean that he had completely surpassed those sixth- and seventh-grade alchemists in extracting the essence of medicinal power.

The palm of his hand pressed on the pitch-black fire mouth of the Black Emperor Ding again, and the soul power surged into it, and then his heart moved, and the pale cyan flame, with a 'bang', rose again.

With a slight wave of his empty left hand, a honeysuckle plant flew into the air, fell into the ding, was wrapped in flames, and quickly refined.

For Han Chen, having found the best medicinal herbs that are hotly spotted, it is no longer difficult to kick away the essence of medicinal power.

Under the control of Han Chen's soul power, the temperature of the flame increased rapidly, and when it reached the time when the honeysuckle was at its best, it stopped increasing in an instant.

The honeysuckle, which is at its best in the heat spot, quickly withers, then slowly cracks and breaks. At the same time, a trace of pale golden medicinal essence was slowly refined from it.

After a while, Han Chen's heart moved, the pale cyan flame was instantly retracted, and with a wave of his palm, the essence of medicinal power extracted from the honeysuckle flew out directly from the tripod and caught it with a jade bottle.

But Han Chen didn't even look at it, directly corked the bottle, and threw it aside.

Immediately, his right hand pressed on the fire, and in a moment, the pale cyan flame rose again, looking at the honeysuckle on the ground, Han Chen groaned slightly for a moment, and then waved his empty left hand lightly.

Suddenly, five honeysuckles rose into the air and fell into the Black Emperor Ding.

That's right, this time, Han Chen was going to refine five honeysuckles at once to refine the essence of medicinal power.

For him, it is no longer difficult to find the best hot spot honeysuckle and refine the essence of medicinal power, and the reason why he continues to refine it is just to enhance the sense of receiving.

However, it is also refined, but it does not have to be done step by step. The five strains were refined together, not only in terms of quantity, but also in terms of difficulty, which was also greatly enhanced.

Because this requires the alchemist to concentrate on five purposes, otherwise, he will lose sight of one or the other, and may even not be able to complete the refining of one strain in the end.

On the surface, doing so doesn't seem to have anything to do with Han Chen's original intentions.

But in fact, whether it is a dual-purpose or a five-purpose purpose, it is a test for the alchemist, testing his control over the amount of soul power, and testing his control over flames.

For both of these points, if you can control them at will, then the difficulty of finding the best hot spot will be greatly reduced.

Of course, if you want to refine medicinal materials for multiple purposes, the premise is that you already know the best hot spots for this medicinal material.

Through soul perception, all the changes in the Black Emperor Ding were clearly perceived by Han Chen.

After all the five honeysuckles fell into the pale cyan flames, Han Chen didn't hesitate at all, and his soul power split into five, entered the flames, and attached himself to the five honeysuckles.

Immediately, his mind moved, and he began to rapidly raise the temperature of the flames and began to refine.

The minimum standard of a first-grade alchemist is to be able to achieve a single-minded and three-purpose approach, because this is the requirement of the most inferior first-grade elixir.

Han Chen's limit is one heart and seven uses, and this is already the peak level of a first-grade alchemist, if he can reach one heart and nine uses, and can freely refine a second-grade elixir, it means that Han Chen's soul power has advanced to the level of a second-grade alchemist, and he also has the qualification to refine a second-grade pill.

One heart and seven uses and one heart and nine uses seem to be not much different, but only Han Chen himself understands the difference.

If you want to achieve one heart and nine uses, you can only wait until your soul power is increased and you can advance to the level of a second-grade alchemist, and according to the current progress of promotion, it will take at least three months, maybe even longer. (To be continued......)
