Lin Xuan showed a look of satisfaction on his face, patted the storage bag, and took out all the Shui Yun Zimu Sword and Wu Hook, the brilliance was dazzling, and it only took a stick of incense to open up a simple cave mansion.

Anyway, it's just a temporary residence, and he will leave after he succeeds, and Lin Xuan didn't do much to embellish it, just casually cut out a few stone chambers.

Then with a flick of his robe, the colorful array flags were sacrificed by him one by one, this Extreme Yin Evil Spirit Array Lin Xuan was already familiar with it, so it was very easy to arrange.

With the protection of this array, even if a cultivator from the early stage of Ning Dan came, he could resist it for a day or two.

Subsequently, Lin Xuan arranged two more tricks, with his current cultivation, plus this method learned from the Nine Heavens Xuangong, I believe that even if he is a master of the Ning Dan Period, if he is not very careful, he is very likely to be deceived.

After the end, Lin Xuan took out a talisman and handed it to Yue'er's hand, instructing her to sacrifice this talisman when she condensed into a golden pill and thus appeared an aura vision.

Although it is highly likely that this is redundant and there are no people in the vicinity at all, it is better to be careful than to make a mistake.

Lin Yue'er naturally nodded obediently, she didn't practice during this time, and tried her best to protect the young master.

Smiling at Yue'er, Lin Xuan turned into a ray of light and entered the new cave mansion.

He was not busy cultivating, but first slept for a night, and then continued to meditate, and his energy and mana returned to their best state. Then he came to the practice room, flipped his hand, and took out a crystal clear jade bottle, the cork was opened, and three red and white pills the size of a dragon's eye were poured out by him.

On the surface, this medicine had lost all its spiritual power, and it was similar to a waste, but Lin Xuan's face showed a precious and important expression.

Tianchen Dan!

Fenghua peerless earth elixir mountain founder left behind the miraculous medicine. It once made the entire Youzhou cultivation realm crazy. It's an old monster like the Extreme Demon Venerable. I also used to do it myself.

Legend has it that after taking this medicine. Those who have cultivated the truth in the great consummation during the foundation building period. Ten of the best can easily succeed in condensing pills. And even if it's for the condensation primordial baby. This medicine also has a great additive effect.

Yuan Baby. For Lin Xuan. It's still too far away.

There is a ninety percent chance of success in the condensation. This effect is really to the extent of going against heaven and earth. It's no wonder that the masters of the two realms of righteousness and demons were crazy about it.

It's a pity that the Heavenly Demon Lord has a strong temperament. Rather for the jade crushed. Nor is it complete. Seeing a corner. actually fused the Chiyuan Dan with this thing. Thus turning it into waste.

With the power of the Extreme Demon Venerable, he could only stare dryly, and left in a huff.

On the contrary, it was Lin Xuan, who was hidden in the shadows, who picked it up.

With the blue sea of stars, he could naturally refine this thing again.

However, looking at the red and white pills in his hand. Lin Xuan's heart was inexplicably nervous, no wonder, whether it was the earliest purification of the Purifying Pill, or the later Zhuji Pill, or the Concentration Pill a while ago, he had a lot of these pills, even if the purification failed, he would not feel distressed, but there were only three Tianchen Pills.

Besides, purification isn't a panacea. As long as it fails once, the elixir will be completely scrapped.

Looking at the three pills lying in his palm, Lin Xuan didn't dare to start.

After a long time, he took a deep breath, and finally picked up one of them as if he had made up his mind, and held it in his palm.

Close your eyes, have no distractions, and mobilize the blue sea of stars in your body. Sky. From the morning sun rises above the horizon until the sun sets in the afternoon.

Finally, Lin Xuan raised his head, his eyes opened, and two pills that were much smaller appeared in his palm, one was snow-white, crystal lovely, and the other was red, and there was a faint heat emitting it.

Tianchen Dan!

Lin Xuan took the white elixir and played with it.

After a long time, he and Chi Yuan Dan were put away separately.

Subsequently. Back to the living room to sleep.

The next day. After the physical strength and mana are restored, the purification will begin again.

That's it. It took three full days for Lin Xuan to purify all three Heavenly Dust Pills, but fortunately, he didn't fail once.

However, Lin Xuan did not take this pill immediately, but after a little muttering, he rested for another night.

The next day, it was carefully purified again.

Different from the common pills in the cultivation realm, such as the Cleansing Pill, the Zhuji Pill, and so on, this Tianchen Pill has only appeared in three pills so far, and naturally there is no way to distinguish the grades.

However, according to Lin Xuan's thoughts, even if Master Zu had the ability to penetrate the heavens and the earth, there must still be a lot of impurities in it.

Every time the impurities are purified a little more, the greater the effect of the Dust Pill will be, and for the impact of the Ning Dan period, Lin Xuan is determined to win!

Of course, he was very careful in this process, adhering to the principle of doing what he could, and it took a few more days for the three pure versions of the Earth Heavenly Dust Pill to arrive.

Afterwards, Lin Xuan took one and began to meditate cross-legged.

Soon, the medicinal power dissolved in the abdomen, and with the spiritual power, it flowed through the eight veins of the Qi Sutra.

The expression on Lin Xuan's face became more and more solemn.

After 7749 days, Lin Xuan took the second Tianchen Pill.

Keep practicing!

In the blink of an eye, he has entered the bottleneck of ninety-nine eighty-one days.

Yue'er was bored and kept outside, although she had a blood contract with her, she and the young master could have the same mind on weekdays, but now Lin Xuan was meditating with all her might, her divine sense was restrained, and there was the barrier of the Extreme Yin Evil Spirit Array, so she didn't know anything about the situation inside!

Several times, she wanted to fly in to have a look, but she was afraid of disturbing Lin Xuan's retreat, so she had to grit her teeth and hold back. Young Master Jiren Tianxiang, there should be nothing wrong!"

Yue'er clasped her hands and prayed silently, for Lin Xuan, Yue'er has always been very grateful, she was originally just a small lonely ghost, if it weren't for the young master, how could she be where she is today.

Yue'er was praying for Lin Xuan's safety, and the sky suddenly darkened.

A moment ago, the sun was still like a flame, hanging high overhead, and suddenly, it inexplicably became dim, as if it was a solar eclipse.

It was obviously a clear sky, but there were strange lightning bolts piercing the sky, and the extremely thin aura around it suddenly became thick for some reason......

"It's ......"

Yue'er was startled, and then she was overjoyed, there was only one explanation for this celestial omen, and the young master had reached the critical period of Jindan's formation.

In a flash of blue light, Xiao Yue'er had already appeared in the sky above the barren mountain, and with a wave of her jade hand, she offered the spirit rune that Lin Xuan had given her.

After the talisman burned, it turned into a light shield and enveloped the entire barren mountain in it, all the spiritual energy was blocked, and the celestial signs quickly disappeared.

However, before Yue'er had time to take a breath, a chill suddenly appeared on Yurong, and a powerful spiritual power was rapidly approaching here.
