Zhou Xingming thought hard, and finally painfully attributed the reasons to three points: first, his cultivation level was not high enough; second, he did not have a deep understanding of the exercises and was not familiar with the application.

Zhou Xing sighed and returned to the hall with the golden eyes and mud. After closing the door of the temple, he took a few deep breaths and stared with breath, took out the iron-hearted cauldron from the ring, and observed the cauldron for the third time.

After that, almost every hour passed, there was such a shout in the hall: "Set! Set! Set!... Set it to me! Ah, it's still not working! It's still fake! Fake exercises, lie, I want Change the exercise method! I want to re-elect!... Set it up! Set it up! Give it to me! Why is it still uncertain? Fake, it's a fake exercise! I'm fooled!..."

A few days later, Zhou Xing was already shouting dry, physically and mentally exhausted, but he was still pointing his golden eyes with his hands, shouting "fixed" in a hoarse voice. The latter seemed to deliberately didn't cooperate with him, always moving around, non-stop.

Helpless, Zhou Xing closed his eyes again, but he could clearly see Tiexinding.

Zhou Xing took a deep breath and finally completed Guanding. This step took far more time than he expected.

After that, he took out a cloth bag from the apse, which was significantly larger and heavy than the one with mud and golden eye food.

A strange medicinal fragrance filled the hall.

Mud raised his head suddenly, and Jin Jing looked at him.

"Don't don't don't, this is not for you to eat, this is for me to reconcile medicine, don't make trouble, if make trouble, I will go crazy." Zhou Xing nervously said.

Hearing that, Jin Jing meowed a few times, and then lay on the ground. The mud screamed, but the sound was not very pleasant.

Seeing that the two of them didn't do anything extra, Zhou Xing let go of his hanging heart and poured out all the medicinal materials in the cloth bag, making the medicine in the hall more intense.

Although they are all low-grade medicinal materials, Zhou Xing is still very excited. This will be the first step he needs to take to become a pharmacist.

Now his main spiritual veins are complete, and with the first-level cultivation base of the first glimpse, he has been able to refine five kinds of pill, namely the battle spirit pill, the restraining pill, the **** action pill, the qi pill and the true martial pill. Among them, the Zhenwu Pill is the most difficult to cultivate, and the Battle Spirit Pill is the best.

Zhou Xing didn't think he was a genius in refining medicine, he was even ready to refine all the medicinal materials in front of him into waste residue. Therefore, he must first refine the battle spirit pill that only needs one kind of medicinal material.

The prescriptions, refining methods, and precautions of these low-level pills are recorded in detail in the "Essence of Pills", and Zhou Xing was overwhelmed by memorizing early.

Even so, Zhou Xing did not rush to do it, but closed his eyes to meditate, adjust the body and mind to the best state, and waited for the best time for refining medicine.

Finally, it was two noon.

Zhou Xing suddenly opened his eyes and patted the ground. The unyielding root plant closest to him jumped up and suspended in front of him.

Zhou Xingqiang pressed the excitement in his heart, pinched the tactics with his hands, released aura, and drew the medicinal materials into the iron-hearted cauldron.

Once he started refining medicine, from beginning to end, the pharmacist should not touch the medicinal materials with his hands. No matter how small it is, he must use aura to complete it. It took him three full days to master it.

Zhou Xing really didn't have much confidence in his talent for refining medicine, so he had to think about it before doing every step, and he did it carefully, without the unrestrained and unrestrained freehand brushwork that Shao Mingjiu had when refining medicine.

Really knowing the difficulty of refining medicine, Zhou Xing paid homage to Shao Mingjiu.

Even so, Zhou Xing had no fear of retreating in his heart, but a bit of joy was born. Because he knows that he never gives up on what is decided.

"Fire!"

Zhou Xing cried out, two groups of gray aura flew out from his fingertips, one group flew into the bottom of the cauldron, and the other group flew into the cauldron to tightly wrap the unyielding roots. In an instant, the two groups of spiritual energy turned into raging fire.

Unyielding roots are the toughest among the low-grade medicinal materials, and have extremely high requirements for the temperature of aura fire. Zhou Xing concentrated all of his attention, continuously pumping the spiritual energy into the cauldron, and soon he saw sweat on his forehead, but he didn't even burn the skin of the unyielding roots, just a little burnt.

Zhou Xing took a violent breath of fresh air in the gap, and the hand-pinch technique changed. This time, he decided to let go and call all the auras in the five spiritual veins at the same time, and the fire inside and outside the iron heart cauldron became more intense.

To maintain the current firepower and continue to increase the firepower, this requires the alchemist to continuously output aura. The requirements for the control and the amount of aura are extremely high. This alone is an arduous test. No wonder the master would say Refining medicine is more difficult than practicing.

Because Zhou Xing was the day after tomorrow’s spiritual energy turned into fire, the flame temperature rose extremely slowly. Following this trend, even if he squeezed out all the spiritual energy in his body, he could not refine his unyielding roots into a battle spirit pill.

Zhou Xing was never a rigid person. Once he figured this out, he immediately thought about how to break the situation to resolve the current embarrassing situation.

He thought about taking a middle-grade aura pill, with the huge amount of aura contained in it, it should be enough to support him to refine the pill, but then he denied the idea of ​​losing money.

He also thought about adding auxiliary materials to accelerate the flame combustion, but he quickly rejected it because his experience in refining medicine was too poor. Adding new raw materials rashly added new variables, which would only increase the difficulty of refining. What is the difference in fire fighting? What's more, he didn't know what auxiliary materials could accelerate the flame burning.

After thinking about it, Zhou Xing decided to take a different approach, adding a little real energy to the aura, which might receive unexpected miraculous effects.

As long as he said nothing, Zhou Xing picked up the true dragon energy and slowly incorporated it into the aura. With this step, the aura seemed to have encountered a major enemy and became very unstable.

When Zhou Xing saw that there was a door, he was delighted, and hurriedly punched the spiritual energy mixed with a little real energy into the cauldron, and the flames immediately raged.

Zhou Xing is overjoyed.

But before he could do anything, he heard a bang, and the unyielding roots suddenly exploded and turned into a pile of medicine dregs.

Zhou Xing was dumbfounded.

Although the unyielding root is more common in the back yam forest and its grade is not high, it is relative to other medicinal materials. If it is sold in the yam medicine shop, it is worth at least a thousand taels of silver.

It didn't take much time, and Qianliang silver turned into ashes. It was because Zhou Xing was born in a wealthy family, and he felt painful.

He felt that he could no longer concoct medicine rashly, otherwise he would be violent.

However, Zhou Xing had accidentally discovered through the inflexible roots exploding into ashes, that is, mixing the true energy into the spiritual energy, and the destructive power of the spiritual energy would suddenly increase.

It's just that this kind of destructive power is extremely difficult to control. Once there is an accident, the fierce true energy and the agile spirit are strongly incompatible... Zhou Xing can't imagine the scene.

For the next ten days, Zhou Xing stayed behind closed doors, and went on a test of external fusion of the two gases. Even though he proceeded carefully, he still suffered serious injuries.

Zhou Xing knows that he has no retreat. If he can't learn how to make medicine, the road ahead will be extremely difficult.
