It was not difficult for Han Chen to use five medicinal herbs at the same time, although the difficulty of refining five medicinal materials at the same time had increased a lot, but it was still within Han Chen's control.

The temperature of the flame rises rapidly, and the enhancement stops at the best hot spot, and the refining is rapid.

Soon, all five honeysuckles withered, cracked, and shattered, leaving only five clumps of pale golden liquid.

After refining for a moment again, the flames were extinguished, and five pale golden medicinal essence essences flew out of the Black Emperor Ding and were packed into the jade bottle by Han Chen.

Without stopping, Han Chen once again put the five honeysuckle plants into the Black Emperor Ding for refining.

Although the loss of the essence of alchemy medicinal power on the amount of soul power is not small, with the amount of soul power that Han Chen has at this time, it can only be used for a short time.

With a 'boom', five clusters of pale golden medicinal essence flew out of the Black Emperor Ding and were packed into the jade bottle by Han Chen.

After taking a look, he put the plug on and tossed it aside.

He exhaled lightly and refined it, and at this time, Han Chen's soul power had already consumed thirty percent, which was not much.

Without a reason, Han Chen's gaze swept over the many medicinal herbs on the ground, and soon, he landed on one medicinal herb.

Purple Star Root. The appearance looks somewhat similar to the rhizome of a plant, only about ten centimeters long, two fingers wide, and the whole is purple, and a little light shines on it from time to time, looking like a star.

This purple star root is slightly more precious than honeysuckle, and its effect has a miraculous effect on trauma, and it is an indispensable medicinal material among many traumatic elixirs.

Although slightly more precious than honeysuckle, it is not really a rare thing. In terms of quantity, it is slightly less than honeysuckle, only thirty-six!

Retracting his gaze, Han Chen pressed his right palm on the fire mouth on the Black Emperor Ding, the light cyan flame burned in the Ding, and with a slight wave of his left hand, a purple star root rose into the air and fell into the Black Emperor Ding.

With a move in his mind, he lowered the temperature of the pale cyan flame to a minimum, and after the purple star root fell into the flames, he did not hesitate at all. Quickly ramp up the temperature.

When the temperature of the flame reaches the optimal hot spot of honeysuckle. The purple star root has not changed much, and it is clear that its optimal hot spot is significantly higher than that of honeysuckle.

Then Han Chen slowed down the speed of the flame problem slightly, and slowly increased.

The first refining of each medicinal herb is the most difficult. It's also the most exhausting. Because I don't know where the best hot spots are. I can only explore a little bit, try a little bit.

This requires extreme concentration of the mind, without the slightest trance. And you need to be patient.

"Is this here? No, it should be a little better!"

Under Han Chen's attempt, the temperature of the flame increased at a lower and lower rate.

Suddenly, Han Chen's heart jumped, "Oops, the temperature is high!"

Click

In an instant, in Han Chen's perception, the purple star root in the ding instantly withered, and a trace of crack appeared.

Although Han Chen had already lowered the temperature at this time, sensing this crack, Han Chen sighed lightly, and he knew that the refining of this purple star root had failed.

As soon as his mind moved, the temperature of the flame skyrocketed instantly, and the purple star root in the flames instantly collapsed and shattered under the high temperature, and then was burned into ashes.

After disposing of this waste purple star root, Han Chen did not pause, and with a wave of his arm, he swept a purple star root again and threw it into the flames in the ding.

The second refining process began again.

Although after the refining of honeysuckle, Han Chen's feel and feeling have improved a lot, but for this purple star root, which has never been tried to refine, it is not enough to be able to find the best hot spot and refine it smoothly after just trying it once.

Looking at the lilac liquid in the jade bottle in his hand, Han Chen frowned slightly, then shook his head and sighed lightly, without even a stopper, he directly threw it aside.

The essence of the purple star root is actually the little bit of light on it, so the essence of the medicinal power extracted by it is not only dark purple in color, but also more intense in that little bit of light.

I closed my eyes and pondered, and quickly recalled the refining process of the previous two times in my mind, and continued to analyze and summarize.

After a moment, Han Chen opened his eyes, and without hesitation, he waved his hand and rolled up a purple star root and threw it into the flames within the ding.

As soon as his mind moved, the pale cyan flames suddenly swelled like a volcanic eruption.

"This is it!" When the temperature of the flame reached a level, a fine light flashed in Han Chen's eyes, and the amount of soul power surged, instantly controlling the temperature of the flame and stabilizing it.

Subsequently, under the calcination of the flame's high temperature, the purple star root quickly withered and shattered.

With a 'boom', a cloud of dark purple liquid flew out of the ding, was accurately caught by Han Chen, and was packed into the jade bottle.

Looking at the essence of medicinal power in the bottle, a smile appeared on Han Chen's face.

The color is deep purple and viscous, with a little bit of light and shines, and it looks very bright.

This is the essence of the purest medicinal power of the purple star root.

"Hehe, the progress is quite big!" Guiguzi smiled slightly in the sea of knowledge.

The refining of the purple star root, although it was only at the third time, found the best hot spot and refined the essence of medicinal power.

But compared to refining honeysuckle before, this time Han Chen's progress was indeed not small.

The Purple Star Root was refined for the third time, and Han Chen seemed to have been refined hundreds or thousands of times.

The increase in the temperature of the flame is incomparably accurate, and the position of the best hot spot for the purple star root is also extremely accurate, and the mastery of the flame after the most is also more decisive and skillful!

Compared with the third refining of honeysuckle, it is indeed a lot of progress.

After finding the best hot spot for the Purple Star Root, Han Chen also directly rolled up five of the thirty-three Purple Star Roots that were born, like honeysuckle, and began refining them together.

When the last few purple star roots were also refined, Han Chen's feel and feeling were also enhanced a lot.

However, this is not enough, he needs not to try twice, until the third time to succeed, nor to try once.

It's a perfect success the first time.

It took two pillars of incense to recover the amount of soul power, and then Han Chen continued to refine non-stop.

This time, Han Chen took out a total of more than two hundred medicinal herbs, each of which had different quantities, more and some less, but the least was more than thirty plants.

If all of them are combined, there are almost 10,000 medicinal herbs.

The pale cyan flame continued to burn, and one medicinal herb after another was thrown into it and refined.

As time passed, the herbs on the ground gradually decreased.

With the decrease in medicinal materials, Han Chen's feel and feeling for refining the essence of medicinal power have also increased rapidly, and the success rate of refining the essence of medicinal power has also increased a lot.

Occasionally, you only need to try once, and the second time you can find the best hot spot and refine it smoothly.

This is exciting news for Han Chen.

It's just that Han Chen didn't find out.

As the rarity of medicinal materials increases, the best hot spots continue to increase, and the temperature of the flame also increases.

On the inner wall of the Black Emperor Ding, the blurred lines appeared more and more frequently, and gradually became a lot clearer.

However, the appearance of the lines on the inner wall of the Black Emperor Ding has always been perceived by Guiguzi.

"Does it need to reach a certain height for it to fully manifest?" Guiguzi said secretly in his heart. (To be continued......)
