The black and white light clusters continued to rotate in the silver-white Dan furnace, and the entire Heart Cultivation Hall was constantly changing color with the two balls of Dan materials in the Dan furnace at this time.

A stream of other danxiang wafted out from the silver-white Dan furnace in front of him, the pill had not yet been refined, and this Dan incense was already so strong, the pill in this Dan furnace was naturally not ordinary.

At this time, Wang Kan no longer thought about the previous things about the "Empty Cicada Ghost Worm" and the "Ghost Clan", but watched with full attention as Master Che Dan really refined the pill.

And Che Dan Zhenren, who was refining the pill, found that Wang Kan was standing by his side at this time, looking at his alchemy with interest, and his heart was also extremely satisfied.

For Wang Kan, an apprentice, Che Dan Zhenren has actually always been cultivated with the educational policy of "Great Dao Tiancheng".

To put it bluntly, it's free-range!

Only when necessary, make some reminders and give the necessary help, and other than that, everything is left to Wang Kan to learn and understand.

Because the way of cultivating immortals, especially the Dan Dao, what is most needed is the ability to comprehend, if everything is taught by words and deeds, it is undoubtedly a great drain on the disciple's ability to perceive.

Therefore, it must be cultivated in accordance with Che Dan Zhenren's "Great Dao Tiancheng" method in order to develop Wang Kan's self-comprehension ability.

And of course, this is not because Che Dan is too lazy to teach, it is purely his hard work!

Che Dan Zhenren's mind moved slightly, and he no longer thought about it, but put all his spiritual sense into the Dan furnace in front of him, and what he was refining at this time was a high-grade spiritual elixir, Liangyi Dan.

Dan Dao is different from casters.

An immortal soldier Lingwu may have been passed down from generation to generation since ancient times, or it may be like the Taixu Xuanshi Sword in Wang Kan's hand, forged through some special means and materials, and can be improved with the improvement of the realm of the owner of the Lingbao.

Once the pill becomes a pill, the grade of the pill is fixed.

Moreover, the elixir is a consumable thing, and it cannot be passed down from generation to generation like those immortal soldiers and spiritual martial arts.

And now, in this world, there are very few sects and Dan Dao monks who can refine the elixir.

On the one hand, it is because it is extremely difficult to collect Dan materials, and more importantly, there are very few Dan prescriptions of immortal pills that can be handed down to this day.

According to legend, Che Dan Zhenren was originally located in the Guhe Sect of the First Dan Sect in the Five Prefectures, which contained five Xian Dan pills, and among them, three were immortal low-level and two were immortal middle-level, and as for the legendary immortal high-level Dan Fang, the five states were so large that it was difficult to find.

Therefore, if an ordinary Dan Sect can refine a high-grade elixir, it can be regarded as having some status on the way to the Dan Dao.

At the Spirit Pill Meeting in Xuantian City before, the Fourth-rate Danmen Cloud Mist Gate in Dongzhou was just offering a mortal high-grade Tunadan, and the Spirit Pill was definitely reluctant to take it out and give it to the Spirit Pill Sect at the Spirit Pill Meeting.

Therefore, looking at the entire land of Dongzhou, except for Che Dan Zhenren, I am afraid that only some hidden elders in the Spirit Pill Sect can refine this kind of high-level elixir.

In the silver-white Dan furnace made of Taixu Meteorite, the two clusters of light, one black and one white, were rotating faster and faster at this time.

"Heaven and earth are infinite, Wuji gives birth to Taiji, Taiji gives birth to two instruments, and two instruments transform into four images......"

Wang Kan looked at the two balls of light in the Dan furnace, and almost subconsciously thought of the content in such a passage of "Yi Chuan".

"I Chuan" is not "I Ching", according to legend, it is the notes made by the great sage Confucius in the previous life when he was studying "I Ching", and Wang Kan actually couldn't remember all the contents, and only said two relevant sentences at this time.

And Che Dan Zhenren, who heard Wang Kan read this sentence softly, suddenly trembled in his heart!

The two clusters of light that continued to hover in the Dan furnace suddenly accelerated at this time, and vaguely, they seemed to have turned into four clusters of light.

Seeing such a mysterious scene, Chu Mo, who had been worrying about it, was taken aback, and couldn't understand how it had become four light clusters now, even though there were two light clusters just now.

However, Wang Kan does know it all.

This thing, to put it bluntly, is the visual persistence of light.

Because the two light clusters in the Dan furnace rotated too fast, leaving visual residues in the human eye, as if four light clusters had appeared.

"Buzz ......"

A gentle humming sound came from the Dan furnace, and the originally extremely strong Dan incense was even more dense at this time.

"It's done!" Wang Kan exclaimed.

I saw that the original two light clusters in the Dan furnace had merged into one at this time, but the person maintained an extremely fast speed and rotated in the Dan furnace.

A faint halo surrounded the elixir, constantly circulating and shining, and the danguang was dazzling, like a jeweled orb.

With a wave of his hand, Che Dan Zhenren wanted to stop the pill that was spinning at great speed, but he was stunned to find that the pill was under his control, and the rotation speed did not decrease at all.

"Wow ......"

"Boom Rumble......

A thunderbolt suddenly pierced the roof of the Heart Cultivation Palace, and came straight to the Dan furnace in front of Che Dan Zhenren.

"Dan Tribulation?" Che Dan Zhenren was taken aback.

However, this thunderbolt struck the Dan furnace made of Taixu Meteorite Iron, but it did not leave any trace.

This Dan furnace made of too void meteorite iron can really resist the Dan Tribulation!

Wang Kan saw that the Dan Tribulation had no effect on this Dan Furnace, and his heart was suddenly overjoyed, thinking that he would also go to the so-called Xuantian Peak as soon as possible to find the Tianxuan Immortal Grass, and then let Wanyi Yuanjun build such a strong Dan Furnace for himself.

Wang Kan was happy in his heart, but Che Dan Zhenren was like a great enemy at this time.

"Woo Woo ......"

Three spirit swords that either flashed with a faint green light or a faint cyan light appeared on the Dan furnace, and Che Dan Zhenren also opened his eyes and looked at the top of the Heart Cultivation Hall that had been shattered by the thunder just now.

Wang Kan also understood at this time why Master Che Dan Zhenren was so nervous, this Dan Tribulation, I am afraid that there is more than one.

"Wow ......"

"Boom Rumble......

Sure enough, a thunderbolt slashed towards the Dan furnace, and with a keen wave of his hand, Che Dan Zhenren blocked the Dan furnace with a spirit sword.

The thunder carried the power of heavenly punishment, and the fierce and tenacious wood spirit true yuan on the spirit sword controlled by Che Dan Zhenren suddenly fell into a short stalemate.

"Click......"

The spirit sword that was obviously not bad shattered, and the true yuan was agitated, and Wang Kan and Chu Mo, who were standing on the side, were almost unable to resist it.

But fortunately, at the cost of the shattered spirit sword, the result in exchange was still good, and this heavenly punishment thunder tribulation was resisted by the spirit sword.
