There are a total of fifty-eight kinds of refining medicinal materials in Mu Yuandan, which means that it needs to be fused fifty-seven times.

Fifty-seven times, and if only one of them does not succeed, it is considered a failure.

Han Chen's mind was highly condensed, and he slowly fused the essence of medicinal power step by step in order.

It's a slow process, and it's not rushed, it's not fast. Moreover, it is also a great test for the soul power and cultivation of the alchemist.

If the soul power is not enough, it will not be able to support the completion of the refining, and the result will naturally be failure.

If the cultivation is not enough, the true yuan will be exhausted in advance, the flame will not be supported, and it will be extinguished, and the result will also be a failure.

Han Chen's soul strength is strong, and his cultivation has fully met the requirements, so there is no need to worry about these two points at all, and the rest depends on Han Chen's own performance.

Time passed slowly, and the essence of the medicinal power in the medicine tripod continued to merge. The newly fused essence of medicinal power, under the calcination of the flame, the impurities were quenched again, and then continued to fuse

Two hours have passed!

"It's done!"

Exhaling heavily, Han Chen's face relaxed slightly.

Inside the medicine tripod, the essence of fifty-eight medicinal powers was completely fused into one, the color was pale green, about the size of a baby's fist, and under the calcination of the flames, a faint medicinal fragrance wafted out.

This is just a dan embryo, the essence of the medicinal power in it has not been completely integrated, and then it needs to be calcined with a flame to fuse the essence of various medicinal powers, and the new impurities produced are refined, and at the same time catalyze the fusion of the medicinal power, complete unity, this process is Ning Dan.

Exhaling slightly, calming down his breath, Han Chen's eyes and jaws lifted, and he turned on the True Yuan, urging the flames and began to condense the pill.

This process is the same as the Rong Dan just now. Pay attention to slow work and meticulous work, and also be in a hurry.

Two more hours passed.

Inside the medicine pod, the baby's fist-sized dan embryo shrunk several times, the size of a dragon's eye, the color was emerald green, and the medicinal fragrance became more intense. It escaped, filling the entire Dan room.

"Almost!"

With a soft sound, Han Chen opened his eyes.

After six hours of refining, up to now, everything has progressed smoothly, and then the last step is the quenching pill!

With his left hand, he pinched out three seal knots, and his mind moved, and the true yuan in his body was surging. With a 'boom', the samadhi true fire in the medicine tripod surged violently, directly submerging the pill, and the temperature soared.

But after only half a breath, the flames came back down, and the temperature plummeted.

At the time of arrival, a very rich Dan fragrance permeated the entire Dan room. Refreshing.

Han Chen's left hand was raised, and a palm slapped on the medicine tripod. With the sound of the 'bell', the medicine pod shook, and then a turquoise pill flew out of the hole in the top cover, and was taken by Han Chen with his hand raised and put into the jade bottle.

"Such a strong danxiang. It should be the best!" Looking at Mu Yuandan in the jade bottle, Han Chen smiled and raised his hand to throw it to Guiguzi, "Teacher, take a look!"

Guiguzi flicked his fingers. The jade bottle hung in front of him and stopped, and the cork was removed, and the elixir rolled out and hung in the air.

"The fragrance is rich, straight to the heart, and extremely pure. The color of the Dan body is as green as a leaf, transparent and flawless!" Guiguzi nodded and smiled: "It's still a little short of the best, it should be the top grade!"

"This is just the top grade," Han Chen pouted.

This Mu Yuan Dan, what he consciously refined was already quite good, and all the steps were almost to the limit that he could reach, with his current level of a fifth-grade mid-level alchemist, this Mu Yuan Dan should be the best.

"Although your soul power has reached the level of a fifth-grade mid-level alchemist, it is only soul power, and for the control of pill refining, you are only at the level of a fifth-grade lower-level, or even a fourth-grade alchemist!"

How could Guiguzi not know what Han Chen was thinking in his heart, shook his head and smiled, put Mu Yuandan into the jade bottle, and then said slowly.

"To be able to refine this Mu Yuan Dan and reach the top grade, it is still due to your soul power being strong enough, otherwise, whether this Mu Yuan Dan can be successfully refined is still a question!"

"Let you refine the pill and practice your hands, it is precisely to let you adapt to it as much as possible, and master the soul power that has been promoted, otherwise, you have to practice what kind of hands, and directly refine the Purple Vein Leaving the Falling Pill!" Guiguzi raised his hand and threw the Mu Yuan Pill back to Han Chen, and said, "Rest, recover the consumption, and then continue!"

"Hmm!"

After putting Mu Yuandan into the empty ring, Han Chen put away the Samadhi True Fire, stepped aside, and began to cultivate, recovering consumption.

After refining for six consecutive hours, the true yuan in Han Chen's body consumed nearly forty percent, this is because he cultivated the Three Dragons Sword Technique, and there is a relationship between the three sword galls, if he changes to someone else, I am afraid that the dantian cyclone will be exhausted before the refining of the pill is completed.

In comparison, the consumption of soul power is even greater, and it consumes sixty percent. After all, it is only the middle level of the fifth grade, and refining the pill of the lower rank of the fifth grade, although the consumption is less, it will not be less.

Soon, half an hour passed, and Han Chen opened his eyes and withdrew from cultivation.

The aura in this Dan Tower was very strong, and it didn't take much time for Han Chen to recover, and the soul power, under the small method, had already been completely restored.

The state was full, Han Chen came to the Five Peerless Peaks, turned his palms over, and took out a large number of medicinal materials from the empty ring.

Guiguzi is right, he is now the time to practice, the five-grade lower-level elixir, it is still not difficult for him, if he wants to improve the alchemy technique, to achieve enough to refine the purple vein from the fall pill, the only way is to continue refining, and then master.

Disheveled!

The Samadhi True Fire rose up in the medicine pod, and soon the preheating was completed, Han Chen waved his hand, and put dozens of medicinal materials into the medicine pod, wrapped in flames, and began to refine.

The pill he was going to refine now was called Jin Yuan Dan.

Like that Mu Yuan Dan, it is an absolute metallic elixir, but it is not a healing pill, but a strength enhancement, making Zhenyuan more sharp and powerful.

However, this is only effective for those who practice metal martial arts, and it is very simple, but it is extremely popular.

And another six hours passed.

The flames in the medicine tripod were extinguished, and a dark golden elixir flew out of the tripod and was included in the jade bottle by Han Chen.

After a slight glance, Han Chen put it into the empty ring, and then cultivated it.

Half an hour later, it was full again.

Keep refining!

This time, the elixir refined by Han Chen, Huo Yuan Dan.

The grades are the same as Mu Yuan Dan and Jin Yuan Dan, they are all five lower ranks, but their roles are different.

The Fire Yuan Pill can boil the true element in the martial artist's body, becoming violent, doubling the destructive power, and becoming more lethal.

It is also only valid for fire-type warriors.

In addition to these three pills, there are also Tu Yuan Dan and Shui Yuan Dan, and Han Chen is also refined, and the effects are even different.

The five kinds of pills are not rare, they are very popular, and they are called the Five Elements Yuan Dan.

However, it is a pity that the refining of Tu Yuan Dan and Shui Yuan Dan, Han Chen both ended in failure. (To be continued......)
