What is Chu Chen's origin, his brother has always wanted him to marry him, and now it doesn't seem so ridiculous, he can be regarded as worthy of himself.

Tang Rou quickly stopped his chaotic thoughts and continued to watch Chu Chen refining the "Digging Spring Pill".

The refining process of the Digging Spring Pill is extremely complicated, and this kind of complexity and cumbersomeness will never be understood by those who have not been refined. There are 31 herbs, and the medicinal properties of each herb and the other herbs are mutually reinforcing, so the process of coordinating the medicinal properties is particularly troublesome.

In addition to these changes in pharmacology, the most difficult part of refining the Quanquan Pill is the two processes of closing the furnace and opening the furnace.

The so-called closed furnace is the process of sending all the medicinal materials into the medicine furnace for incineration, and at the moment when the medicine furnace is closed, the influence of air flow will have an irrepressible effect on the medicine fire in the medicine furnace. This effect can lead to a difference in the temperature of the overall fire.

This slight difference in temperature has no effect on other medicinal herbs, but it has a great impact on the most expensive divine spring water.

The water of the Divine Spring is essentially a kind of spring water, and the so-called water and fire are incompatible, so when refining the Digging Spring Pill, the most difficult thing is to refine the water of the Divine Spring.

As long as there is a slight difference in any link, it is possible to completely incinerate a drop of divine spring water, and at this point, this furnace of elixir can be regarded as waste.

Therefore, when the furnace is closed, it is the time when the pharmacist's control over the flame is tested.

In addition to the closed furnace, the opening of the furnace refers to the process of perfect coordination and unification of the medicinal properties of all medicinal materials in the medicine furnace and thorough smelting into one.

When the furnace is opened, the moment these extremely high temperature air pressures rush out of the intersection of the medicine furnace, it will also cause a big change in the medicinal properties of the entire medicine furnace.

Before refining the Digging Spring Pill, Chu Chen was already familiar with the conflict between the medicinal properties of these medicinal materials.

And after reading the bearded tutor's alchemy technique several times, I can be regarded as having some confidence.

But when it came to the actual incineration, there was still a little trouble.

Chu Chen's Taiyi Purple Blood Furnace was refined from the fragments of Taishang Laojun's Bagua Furnace, so the medicinal fire contained in it was not strictly speaking a mortal flame, and it possessed a unique celestial spirituality.

At the moment when Chu Chen sent all the medicinal materials into the medicine furnace and burned it closed. The flames in the medicine furnace didn't know what was affected, and suddenly the flames skyrocketed, and a blinding purple light shot up into the sky.

Burned all the medicinal herbs to ashes in an instant!

In a cloud of purple flames, all the medicinal herbs turned to ashes!

Shen Hou, Zhou Mei, and even Tang Rou all gasped, because in their opinion, Chu Chen had already done a perfect job, and he would make mistakes.

Only the bearded tutor didn't speak, he had seen too many scenes like this, and he knew that he should let the disciples who were refining medicine summarize by themselves first, and it was not appropriate to rush to appease or build up.

Hmm, what's going on? What's wrong?

Chu Chen frowned, and stroked the delicate induction on the Taiyi Purple Blood Furnace with both palms.

This medicine furnace had already become one with his mind, reaching the point of turning the furnace into the palm of his hand, so after careful investigation, the reason was quickly found.

The spiritual power contained in the innate purple flame inside the Taiyi Purple Blood Furnace conflicted with the innate spiritual power of the water of the Divine Spring.

When the furnace is closed, the purple fire must be suppressed with spiritual power first.

Wait until the water of the divine spring is completely fused with other medicinal materials, and then ignite the purple fire, there will be no problem.

"Don't be discouraged, you have done a very good job, you must know that when many people refine the Spring Digging Pill for the first time, they can't even pass the level of washing medicine, and there are very few people who can persist in the process of closing the furnace. ”

Seeing Chu Chen touching the medicine furnace and muttering silently for a long time, the bearded mentor thought that his disciple was extremely frustrated because of the failure of medicine refining, and finally patted him lightly on the shoulder and comforted, "This time the medicine refining process has a lot to show for it. ”

"Thank you, teacher, I'll try again. ”

Chu Chen smiled and nodded, took out the second Spring Digging Pill material from the storage ring, and began to refine it step by step from scratch.

Tang Rou and the others became nervous again, and the three of them felt that they could hear each other's heartbeats.

And Chu Chen, the person concerned, was much calmer than them, with the experience of the last failure, this time he was extra careful when refining the medicine.

When it came to the moment when the furnace was closed, he directly opened his spiritual sense, accurately controlled every wisp of flame in the furnace, and unhurriedly suppressed the temperature of the flame with spiritual power at the moment of closing the furnace.

When he sensed that the drop of divine spring water was gradually absorbed by a milky white medicinal liquid, he breathed a long sigh of relief, and the light purple flame suddenly rose brightly.

Finally passed the difficulty of closing the furnace, which made Chu Chen's expression relax a little.

Seeing his expression, the expressions of the three onlookers suddenly relaxed slightly.

Only the bearded tutor's face gradually became stern. After all, there is one last difficulty that has not been overcome......

Sure enough, just as the bearded mentor was worried about, the moment Chu Chen waved his arm slightly and lifted the purple furnace lid, a blazing purple light skyrocketed, and in the blink of an eye, the almost completely formed pill was incinerated clean.

"Failed again, the Digging Spring Pill is too **, even if Chu Chen manipulates it perfectly, it still can't work. ”

"After all, we have been in the Medicine Palace for too short a time, and the Digging Spring Pill is really not something we should have touched at this stage. ”

Compared with Zhou Mei and Shen Hou's sighs, Tang Rou still had an expectation in her heart, she felt that Chu Chen still had the possibility to create a miracle and successfully refine the Spring Digging Pill!

After a little guidance from the bearded mentor, Chu Chen started the third attempt, and Shen Hou and Zhou Mei were no longer nervous, because they didn't dare to hold out hope anymore.

In their eyes, Chu Chen's refining process was as perfect as a textbook, and the reason why he couldn't succeed was that he was still too young and the time had not yet come.

The bearded mentor's thoughts coincided with Shen Hou and the others, but the bearded man thought in his heart that the most fundamental reason for Chu Chen's failure was that his cultivation was too low.

There is only the Nine Layers of Spiritual Water, and the first one he refined at that time was already in the Spirit Spring Realm, Chu Chen was in a hurry, and the failure of refining the Digging Spring Pill this time was not a bad thing for him.

No matter how talented a disciple is, it is not a good thing if it is too smooth sailing, and he just took advantage of the failure of refining the Quanquan Pill this time to take the opportunity to educate this precious disciple, which will be of great help to his future.

"Ding!" I don't know how long it was, but the bearded man who was dozing off suddenly heard a crisp sharp sound.
