In those ancient years, Taishang Laojun was known as the Moral Heavenly Venerable, and he was one of the most powerful people in the entire world. There are countless pills, divine weapons, and magic weapons refined in his hands. Over time, it will naturally leave some immortal imprints!

Of course, it was just a legend, Chu Chen never thought that such a legend would now be presented alive in front of his eyes!

That's ...... But Taishang Laojun's alchemy secret technique!!

Almost instantly, Chu Chen opened his spiritual sense to the limit. Carefully observed every movement of the light and shadow of Taishang Laojun. Do your best to memorize those actions in your head. But something disappointed him. In the past, the spiritual consciousness that was invincible and unfavorable, at this time, in front of Taishang Laojun's actions, there was no mystery. Those vague movements were still extremely fast and blurry, and I couldn't understand how he used his aura at all. Only a very small part of the movement can barely catch some vague things.

Taishang Laojun's alchemy secret technique, that is beyond imagination of alchemy. Even if Chu Chen's spiritual sense had reached the level of a "Great Grandmaster", he couldn't understand the mystery at all. Only some of the most superficial and basic means can vaguely figure out a line of artistic conception.

Just as Chu Chen was fascinated and carefully pondered the mystery of those lights and shadows, he saw a slight shock, and the light and shadow in front of him disappeared in an instant, as if they had never appeared before. When I looked closely, I saw that I was patronizing and figuring out the mystery of the law in the light and shadow, but I didn't notice the fire, and as a result, a good Duyuan Dan material was burned to ashes.

"I just got the medicine stove, and I'm not very skilled. It's okay, try more. ”

Those lights and shadows were directly presented in Chu Chen's mind, Senior Sister Qingyue didn't see it, and when she saw Chu Chen, she was a little stunned and refined a medicinal herb, and hurriedly spoke comfortingly.

"Well, senior sister, I understand, don't worry. Chu Chen nodded. This medicine furnace is very magical, only when the elixir is burned and the medicinal gas in the elixir is dispersed, can it hook the imprint of Taishang Laojun in the underworld. When the herbs are burned, the medicinal gas is dissipated. The light and shadow that had manifested were gone.

The second time, Chu Chen already had experience, and when he was going to figure out Lao Jun's alchemy, he also divided a part of his mind to control the fire.

But this time, the image of Lao Jun's alchemy is very strange and did not appear again?

Just when Chu Chen was puzzled, the voice of the little hamster suddenly came from his mind, "Chu Chen, don't look for it, the image of Lao Jun's alchemy will not appear again today." ”

The little hamster was already Chu Chen's blood**, so it could see some things that Chu Chen sensed.

"Why?"

"Because the level of this purple blood furnace of yours is too low, every seventy-two hours, only one-tenth of the image of the pillar of incense can appear. The little hamster replied.

"How do you fix that?"

"How to solve it, the deity is too lazy to answer you, of course it is...... Constantly transform and evolve your small medicine furnace, and you can see more and more images of Laojun's alchemy, more and more, longer and longer, sleeping. ”

The little hamster snorted angrily, quickly fell asleep, and ignored Chu Chen.

At some point, Chu Chen even suspected that it was not a mouse at all, but a pig, which had been eating and sleeping all day long.

Since the image of Lao Jun's alchemy will not appear again in a short period of time, Chu Chen's attention is no longer focused on this.

Instead, he began to concentrate on refining medicine, and soon he was attracted by the purple fire rising from the medicine furnace!

It was only then that he discovered the mystery of this purple flame. This kind of flame is like being born for alchemy, and has an unparalleled sensitivity to medicinal materials, which can delicately incinerate every impurity in the medicinal materials without destroying the medicinal properties of the medicinal materials themselves.

Originally, Chu Chen needed a lot of force to operate the furnace flame, but now he only needs two parts of force, and he feels that he has entered the semi-automatic world of ease from the hard manual world.

The purple fire even seemed to be able to communicate with Chu Chen's soul fluctuations, and changes according to Chu Chen's soul power.

This "Taiyi Purple Blood Furnace" is really amazing, according to the opinions of Master Xu and the little hamster, this is still the lowest level and rough state, if it continues to improve, how powerful the effect will be, Chu Chen hardly dares to imagine.

Chu Chen calmly manipulated the Ziyan refining medicine in the small medicine furnace, but in his mind were some fragments of the lingering image of Lao Jun's refining medicine, and that mysterious feeling made him feel fascinated.

Taishang Laojun's alchemy secret technique is too subtle and profound.

I just couldn't understand it, but Lao Jun's demeanor, movements, gestures, and even the aura flowing on his body when refining the medicine made Chu Chen feel that he had sensed something.

This feeling is like a talented and intelligent martial arts practitioner newcomer, watching the Grand Master make a move, although he can't learn the Grand Master's moves for a while.

However, the consciousness and images left in his mind by the Great Master would give him a sense of epiphany, and then he embarked on a new path.

This is how Chu Chen feels now, after seeing Lao Jun's alchemy, he suddenly feels that his alchemy method should be able to try to improve.

Although Elder Lingxin's alchemy is brilliant, compared to Lao Jun's alchemy, it is simply the difference between a baby and a martial arts master.

However, now Chu Chen could only feel the intention of the Martial Arts Grandmaster, and the other parts could not break free from the Spirit Heart Elder's alchemy system.

Chu Chen shook his spirits and decided to try to imitate Lao Jun's alchemy.

Chu Chen gritted his teeth and began to concentrate, and when he burned the medicine, his hands trembled slightly, and the aura in his body began to be integrated into his alchemy technique according to the meaning of "Laojun Alchemy" in his mind.

Countless Dan intentions are surging!

One, two, three...... 100, 200, 300...... 1,000, 2,000, 3,000......

Finally, under the highly concentrated energy, the three thousand six hundred Dao Dan Intents were perfectly displayed by him, but when he saw that the fist-sized medicinal liquid in the medicine furnace trembled slightly, there was an astonishing change in an instant.

The constantly tumbling liquid instantly spun violently, and in just an instant, it split into two and transformed into the shape of two yin and yang fish rotating with each other. These two groups of medicinal liquids are distinct from each other, but they are close together, converging into a mysterious Taijitu-shaped medicinal liquid, which is slowly condensed.

With the scorching of the light purple flame, the Taijitu-shaped medicinal liquid began to evolve and transform gradually, constantly converging towards the eyes of the yin and yang fish, and began to condense two crystal clear and identical Duyuan Dan, constantly rotating with each other.

When the last trace of flame disappeared, Chu Chen's fingers moved slightly, and the two precious Du Yuan Dan flew into the porcelain plate that had already been prepared next to him. This amount of medicinal materials, which originally only had one pill, was forced to refine two pills under the influence of that strange Lao Jun's medicinal intent!

Chu Chen's body trembled with excitement. It is worthy of the Dan intention of Taishang Laojun!

Driven by the Dan intent of the Tai Chi Liangyi Alchemy, it is possible to refine double the amount of pills with one medicinal material, and this bizarre special effect alone is enough to astonish the world!

However, Chu Chen also knew very well that at present, his Dan intention was still very shallow, and he could refine two Dan with one medicinal material, and this "Taiyi Purple Blood Furnace" also played a huge role.

And at this time, Qing Yue, who had been watching Chu Chen's refining, had opened her mouth slightly, looking at Chu Chen in disbelief.

"How is this possible? The first time I refined the second-order elixir, not only did I succeed, but I also refined the double elixir with one medicinal material, junior brother, you tell me honestly, are you the reincarnation of the god of medicine?"

Qing Yue has always been by the side of Elder Lingxin, and she can be said to be well-informed, even the scene of medicine refining by a pharmacist who is stronger than Elder Lingxin.

But there has never been a day when Chu Chen used that small black medicine furnace to refine the Duyuan Dan.

One herb refines a double pill, which ...... This is impossible for the Great Medicine Master to do, it is clearly a secret technique that only exists in the legendary ancient alchemy that has been lost, how did Chu Chen complete it?

Even if Chu Chen's success rate in refining a first-order pill before was one hundred percent, when it came to a second-order pill, it should inevitably become fifty percent, and the difficulty of a second-order pill could be said to be more than ten times that of a first-order pill.

Chu Chen succeeded lightly, and he also refined double!

In fact, Chu Chen's success this time was also beyond his own expectations, after all, he used the "Taiyi Purple Blood Furnace" and "Laojun Danyi" to create the terrifying effect of Zào.

But Qing Yue, who didn't know the inside story, could only think that Chu Chen was the reincarnation of the God of Medicine, and she muttered, "Where is the little medicine saint, it should be the little medicine god." ”

Chu Chen seemed to consider that his Dan refining seemed to be too shocking, so he didn't use the Taiyi Purple Blood Furnace for the next few days.

However, he had already tried to use the vague "Laojun Dan Intent" that he vaguely understood in normal alchemy, although the effect was not as good as using the "Taiyi Purple Blood Furnace", but it also made the good success rate of his second-order pill reach more than sixty percent.

On this day, Senior Sister Qingyue walked into the Ancient Hall of Medicine Refining in a hurry, and her pace was very brisk.

"Senior Sister Qingyue, why are you so happy?"

Chu Chen, who was refining the Flame Pill, raised his head slightly and asked.

"Hehe, junior brother, Elder Lingxin sent a message today, and her affairs are over. I'll be back this afternoon, and you'll be learning her alchemy right away. ”

"Great, it seems that I will be able to refine the Cold Crystal Xuandan right away and start condensing the first drop of spiritual water. Chu Chen was obviously very happy.

"By the way, one more thing. ”

"What's the matter?"

"This time, Elder Lingxin went out and met a demon girl surnamed Ling, Elder Lingxin has abolished her whole body cultivation and sent her to the sect prison......"

Before Qing Yue's words were finished, the blood fire in the medicine furnace controlled by Chu Chen suddenly soared high, and the void rolled, burning the medicinal materials in the medicine furnace completely, and a cloud of green smoke with a burning smell scattered in all directions.

"Little junior brother, why did you suddenly fail to control the fire?" Chu Chen stood by the stove in a daze, Qing Yue's words didn't seem to be heard at all, just muttered, what should I do? She is such a proud person, she has fallen to this point, how can I help her? Obviously, Ling Xuan fell into the hands of the Spirit Heart Elder, and was abolished from his whole body cultivation, and he was still in the prison of the sect!
