This time, he was still Zhu Chentao's disciple, and Yang Chen's former slave He Lian came to serve. However, unlike the last time, from beginning to end, Zhu Chentao and He Lian were just spectators, and the refining of the materials and the refining of the pill were all handled by Yang Chen alone.

To put it bluntly, when Yang Chen was refining his own pill, he just asked Zhu Chentao and He Lian to learn as much as possible. Although Zhu Chentao was already a master of Yuanying, he didn't dare to surpass Yang Chen on the way to alchemy, and looked at it honestly, for fear of missing a little.

As for He Lian, she was originally Yang Chen's servant, whether it was cultivation or fire alchemy, she was not as good as Yang Chen. Yang Chen promoted her like this, of course she knew how good she was, and she served her master and Yang Chen very thoughtfully, and she didn't dare to slack off in the slightest.

The Questioning Pill requires more than a dozen kinds of raw materials for 10,000 years of fire, and these are all found in the valley left by the Howling Sky Dog. When Yang Chen took out those freshly picked medicinal herbs, even Zhu Chentao couldn't help but fall into a frenzy.

As an alchemist, there are a few times when he can see the elixirs that are more than 10,000 years old, and they are all like this at a time? When Yang Chen was preparing, Zhu Chentao took the trouble to explain the tasting of medicinal materials to He Lian, and at the same time, he could be regarded as having personally touched these rare medicinal materials.

Yang Chen first used the earth core fire to refine all the medicinal materials. The medicinal materials that have been on fire for more than 10,000 years have sufficient spiritual power, which is jaw-dropping. Not to mention anything else, just because the Yunling Furnace was repeatedly edified by this large piece of medicinal gas, it changed its face out of thin air. From that pale green sè to a little pale green, the end is magical.

It's just that the spiritual power that overflows from the refining makes He Lian a little unbearable, so she has to avoid it from afar, and the situation of the surging qi and blood in the whole body has eased.

Officially starting to refine, Yang Chen's fire-resisting technique once again surprised Zhu Chentao. His eyes were fixed on the flames in the Spirit Furnace, and he couldn't take his eyes off it.

This time, Yang Chen used the technique of resisting fire like earth and fire like wood, and the Asking Heart Pill paid attention to making people's hearts stop like water, pointing directly to their hearts, not being invaded by external demons, and the most quiet earth and wood system among the five elements of nature was the most suitable. However, despite the dual refining of civil and engineering, the origin is still flame.

At the bottom of the furnace is a flame as tight as the earth, which is composed of a combination of the earth's core fire and the cold ice flame, and the medicinal liquid refined by the earth's core fire is spread on the top, and under the action of the two flames, it is like a magma that has just melted, slowly softening and flowing.

A miniature Bodhi tree made from the fire of Xuanmu, the trunk of which penetrated the liquid and took root in the fire and ice flames below. The liquid that was close to the trunk of this flame linden tree boiled slightly, spreading the fire to other parts little by little.

Under the Bodhi tree is the most suitable for people to meditate and practice, under this kind of tree, you can enter the meditation peacefully, and at the same time the mood is calm, and the Xuanmu fire transforms into the Bodhi tree, but it is to take this Zen and integrate it into the Asking Heart Pill, which happens to coincide with the medicine of the Asking Heart Pill.

Of course, it is not that the Xuanmu fire can achieve such an effect by transforming into a Bodhi tree. The key is the subtle flame of the Xuanmu Fire, and when the surrounding medicinal liquid is boiled, the tiny Tranquility Formation is directly engraved into the liquid of the elixir. Every drop of the tiniest drop of medicinal liquid contains this tiniest tranquilization array, which is the most fundamental reason.

The Xuanmu Fire can only make the small circle of medicinal liquid around the trunk boil at a time, but it can't make all the medicinal liquids feel the fire, which requires Yang Chen's precise control, and little by little by controlling the other two flames, all the medicinal liquids can undergo the baptism of the Bodhi Xuanmu Fire.

This process alone takes at least a year. The Asking Heart Pill can make people not invade by external demons, relying on this Bodhi Zen feeling. And the kind of coldness brought by the same ice flame can also make people stay awake at all times, which is the reason for pointing directly to the heart. Naturally, the Ice Flame also has the use of the Ice Flame, which is also a magic circle composed of extremely fine flames.

However, relying on the effectiveness of the magic circle alone is not enough to support the function of the Asking Heart Pill. What really plays a key role is the medicinal power of these 10,000-year-old medicinal materials with the assistance of monarchs and ministers. Otherwise, those Mahayana masters can also set up formations, wouldn't it be easy to achieve the effect of the Asking Heart Pill?

In the final analysis, the huge and continuous supply of spiritual power that is not violent is the foundation of everything, and the medicinal power assisted by the monarch and the minister, coupled with the combination of various factors, has achieved the good reputation of the Asking Heart Pill. It was precisely because Yang Chen had absorbed the Ice Flame and Xuanmu Fire last time that he had so much confidence in refining the Asking Heart Pill. Even if Zhu Chentao watched Yang Chen refine the Asking Heart Pill from beginning to end and let him do it again, it was not so easy. Not to mention that the raw materials are difficult to find, just such a superb fire-fighting technique is not something that Zhu Chentao can reproduce.

The entire refining process, Zhu Chentao can only be described as breathtaking. Yang Chen's current method of resisting fire simply made him not know how to describe it.

Now Zhu Chentao and He Lian only believe one thing, as long as they continue to practice according to the way of fire resistance that Yang Chen taught before, the road ahead is far from the end. There will no longer be such a thing as Zhu Chentao thinking that his Jindan was already an insurmountable peak a long time ago.

One year's time was only enough for Yang Chen to add enough formations to those medicinal liquids, and the rest of the time, Yang Chen was still needed to complete the refinement of the Asking Heart Pill.

Surprisingly, at the last moment, Yang Chen was not using a high-grade flame, but one of the first-grade flames that happened to be collected this time. The low-key and restrained flame keeps the most unfazed steps, but always maintains a strong heat.

Originally, Yang Chen thought that he was going to use Bibi fire to do this, but now with these low-level flames, it is more suitable, and the success rate of the pill is also higher.

Finally, ten months later, Yang Chen began the last step of collecting pills. The dazzling collection techniques, Zhu Chentao could barely understand a little bit, He Lian was purely caught in the mí fog, and he didn't understand what Yang Chen's techniques were for.

However, at this critical moment of collecting Dan, no one dared to disturb Yang Chen easily, both of them looked at Yang Chen cautiously, and waited until Yang Chen completed all the actions and put away the flames.

In the spirit furnace, a shining light the size of a bucket suddenly shot out, and the dazzling pillar of light directly broke through the roof and soared into the sky. The earth vein aura in the Burning Sun Courtyard seemed to be suddenly attracted by something, and frantically concentrated towards the Yunling Furnace.
