Generally, the medicine furnace is basically about a foot high, because only a wide enough space can accommodate a lot of different medicinal properties, and the medicinal properties of the main drug, auxiliary drug, and dispensing are harmonized.

But the small furnace in front of Chu Chen's eyes was pitch black, and it was only three feet high, and from the outside, it almost looked like a whole piece of smelted big iron!

This...... This thing can also be used to refine medicine?

At this moment, even many students who originally had confidence in Chu Chen began to have a suspicious look in their eyes: This guy shouldn't have seen the magic of the wooden character seal, and he has already given up on himself after seeing the magic of the wooden word seal, and he doesn't plan to refine the medicine well!

In the midst of everyone's strange gaze, Chu Chen's face was solemn, and he threw the warm yellow remnant sword into the three-foot high medicine furnace...... Don't be fortunate, this Warm Rainbow Sword is only a broken sword, and I want a complete long sword, I'm afraid this furnace can't fit it.

Just when everyone wanted to laugh but didn't dare to laugh, Chu Chen's face was solemn, and after reciting a few words of medicine recipe slightly, his figure brushed and brushed eight steps in a row, and after walking around the medicine furnace perfectly, he punched a gorgeous seal into the three-foot-tall small furnace.

Rumble!

The blue light exploded in the field, as if a turquoise sun suddenly appeared, and the blue light surged out, and around the medicine furnace, a huge flame as high as three zhang long was conjured, and the fire light reflected a piece of turquoise around the surroundings, which made everyone's eyes freeze instantly.

This...... The twenty-four secret seals of the heavens of Daluo are printed with wooden characters, and they are more refined than Huang Yue's wooden character seals!

At this time, the blue flame rising from the medicine furnace in front of Huang Yue was only one zhang high, but the blue flame rose in front of Chu Chen, and the blue flame actually soared to three zhang, completely suppressing the light flame!

However, it was not over, in the shocked eyes of many students, Chu Chen's footsteps did not stop, and he walked around the medicine furnace three times in a row, a total of twenty-four steps.

A dazzling spiritual power light surged out like a tide into the flames, and this torrent of spiritual power actually had a total of three colors: green, red, and gold.

Infused by the three-color spiritual power, the light changed in the three-zhang high blue flame, first conjuring up a lush and incomparably green forest, and then a red heavenly fire fell from the sky, igniting the entire forest, and in the red fire, a dazzling golden sword light churned in the sea of fire, as if it was constantly refining and refining by the flame.

"Wood makes fire, fire alchemy this ...... This is actually the perfect integration of the wood, fire, and gold in the twenty-four secret seals of the Great Luo Heavens!"

With an exclamation, the student's whole body couldn't help but tremble. And after hearing it, everyone seemed to be completely stunned by a thunderbolt in an instant!

The 24 Secret Seals of the Great Luo Heavens are not independent of each other, and in the complete 24 Secret Seals of the Ancient Era, they can complement each other, thus deriving the omnipotent and omnipotent secret arts.

After the later generations sorted out the seven-character seal, it also inherited this characteristic, and each character seal can complement each other, just in combination with the five elements of yin and yang.

Among the many secret techniques of alchemy, people once deduced that if the fire, wood, and gold seals of the seven-character seal recipe were fused into one, the most perfect alchemy would be matched.

Because wood can make fire, and fire can make gold. It can exert miraculous effects when refining the metallic pills such as Sword Body Pill, Vajra Pill, and Iron Armor Pill!

However, one of the words of this seven-character seal recipe is already very complicated, and the difficulty is comparable to that of a top-level alchemy.

Who can master the three secret techniques at the same time, and even if they master the three secret arts, how to smelt them into one is a problem.

You must know that the difficulty of combining these three secret techniques is not as simple as adding one, and its difficulty increases exponentially!

But at this time, in front of the people, this only zài in the legend of the refining technique actually appeared!

At this time, Chu Chen's front was completely shrouded in a dazzling light.

The three-zhang long blue flame evokes a world in which a lush forest burns, providing infinite light and heat.

And in the endless forest fire, a golden sword light continued to refine and purify, gradually exuding a cold sword intent.

With the naked eye, you can see layers of golden sword light, like stars, arranged in the red fire that covers the sky, emitting bursts of dragon-like sword groans.

This spectacle is enough to go down in history!

Can...... How could this be possible for such a young alchemist!

Looking at the solemn look on Chu Chen's young face, everyone felt a sense of rebellion.

The seven-character seal recipe is so secret that it can even be found directly in the main hall of the Medicine Palace.

But there are only a handful of people who can really spend a lot of effort on ascetic cultivation, and they have never heard of it even after comprehending the three-character secret art and smelting it into one person!

Even if some master alchemists exhaust their entire lives, I'm afraid they won't be able to do this!

But now this qiē is vividly shown in a young man who is less than twenty years old...... How is this possible?

Everyone was completely surrounded by a huge shock, and they were almost out of breath, and Leng Qianxue widened even more, with a pair of beautiful eyes full of incredulity.

In fact, the sect master of Xuantian Sect has also been sitting on the throne for a while, and Leng Qianxue thinks that she has some knowledge.

I also knew a lot about some masters of medicine refining, but once I knew those masters, I was as ignorant as a child when I was less than twenty years old in front of me.

Is this still a low-level pharmacist? This is really a low-level pharmacist who can perform alchemy??

In addition to Leng Qianxue, his students have thoroughly admired the five-body cast.

Don't want it, when the three-character secret technique, once it is cast, you can see the level of alchemy of the young master in front of you, which is enough for you to spend your whole life pursuing, or you may not reach the realm.

With such a mentor...... Are you still worried that you can't learn advanced alchemy?

At this moment, not only were many students stunned, but even Huang Yue, who had always been smug on his face before, was almost shocked at this time. The small three-foot-tall medicine furnace in front of Chu Chen was blazing, and the blue light flame completely enveloped the entire space, causing the expression on his face to change several times in a row.
