173: Cave Dzi Beads

The screen displayed a vast number of Spiritual Woods, dazzling Lin Shiming, who also noticed quite a few Heavenly Wood Hearts.

Among them were High Grade Tier 3 Heavenly Cloud Wood Heavenly Wood Hearts, and High Grade Tier 3 Iron Rock Bamboo Heavenly Wood Hearts.

The exchange conditions for these Heavenly Wood Hearts all required killing twenty Late Foundation Establishment Stage demonic Cultivators, which made Lin Shiming extremely eager, almost taking out the token given by Black Flood Dragon Loose Immortal to exchange for them.

However, at this moment, his problem was not a lack of true essence, but a lack of suitable Magical Artifacts.

Exchanging for High Grade Magical Artifacts would be useless as he couldn't control them yet. He could only use High Grade Magical Artifacts, but he was unwilling to settle for that. Therefore, only complete Tier 3 Spiritual Woods were his target for exchange. This time, he wanted to exchange for the Materials needed to refine a complete set of High Grade Magical Swords for the Purple Wood Mysterious Sky Sword Formation.

Lin Shiming checked the Spiritual Woods but found that there were only three types of complete High Grade Tier 3 Spiritual Woods: qingming wood, Yan Yang wood, and Profound Yang wood.

Of the three Spiritual Woods, the first was clearly not suitable for him. However, the second and third made Lin Shiming hesitate. The former Spiritual Wood contained the power of the blazing sun and Yan Yang, and he himself had a fire Spiritual Root. Although he Cultivated the Purple Wood Heart Sutra, using Yan Yang wood could still make the sword formation more powerful, activating the power of Yan Yang, which would undoubtedly be a great weapon against demonic Cultivators and Corpse cultivators.

As for Profound Yang wood, it was an extremely sturdy Spiritual Wood, with a hardness comparable even to High Grade Spiritual Wood, but its drawback was its extreme ordinariness, lacking other characteristics. Furthermore, swords refined from it would become heavier.

Lin Shiming hesitated repeatedly but still wanted to choose the former.

However, just at this moment, a System prompt suddenly appeared:

"Filter all Spiritual Pearls, select the dust-covered great world grotto-heaven pearl, combine it with the auxiliary spirit platform, and you will obtain a Grotto-heaven World!"

As soon as the prompt appeared, Lin Shiming felt his heart suddenly pound.

His hand, which was reaching for the token, immediately retracted, fearing that the exchange personnel would misunderstand.

After re-reading the prompt several times, he finally confirmed that the prompt was not an illusion.

Lin Shiming had only heard of the legend of the Grotto-heaven World in cultivation miscellaneous records. It was said that only Golden Core True Persons could restrain a Grotto-heaven World and make it their own.

Besides this, there were also grotto-heaven pearls, but no one in the entire Zhao Country, or even the entire Yan Region, had ever seen a grotto-heaven pearl, let alone refined one.

The System prompt had never been wrong, which meant there was a grotto-heaven pearl among the exchange items.

Lin Shiming shifted his gaze from the Spiritual Woods and began to examine various pearl Magical Artifacts.

Devouring Demon Pearl, thunder pearl, Profound Extreme Pearl... Lin Shiming looked at each pearl Magical Artifact one by one.

Each Magical Artifact had an introduction, which Lin Shiming skipped directly, regardless of whether the pearl Magical Artifact was a Tier 3 Low Grade Magical Artifact or a Tier 3 High Grade Magical Artifact.

Finally, at the very edge of the screen, he found a mysterious Tier 3 pearl.

The pearl's description stated it was a mysterious Magical Artifact, which could not be refined by dripping blood, was as heavy as ten thousand jun, and could be used for surprise attacks to smash enemies.

As soon as this description appeared, he instantly confirmed that this must be the grotto-heaven pearl. A Grotto-heaven World would naturally be incredibly heavy and unrefinable because the grotto-heaven pearl needed to combine with the spirit platform. Other Cultivators, without the System prompt, would not dare to easily attempt it.

The exchange required twenty Early Foundation Establishment Stage demonic Cultivators.

Lin Shiming was even more surprised now. He hadn't expected that this grotto-heaven pearl would only require the heads of twenty Early Foundation Establishment Stage demonic Cultivators. For him, just from the battlefield when he returned, he had already killed four Early Foundation Establishment Stage Cultivators.

At this moment, he was very conflicted, but in the end, he did not use the token to exchange for this grotto-heaven pearl.

It wasn't that he felt the grotto-heaven pearl was unworthy; on the contrary, he worried that using such a precious token to exchange for the grotto-heaven pearl would make it easier for its true nature to be discovered.

If the Purple Mansion Cultivators of the Three Sects learned the secret of the grotto-heaven pearl, he would have no chance of obtaining it.

Lin Shiming lingered there for a long time, struggling for a long time. Finally, he gritted his teeth, refrained from looking at the grotto-heaven pearl, and used the token to exchange for Yan Yang wood. The exchange condition for Yan Yang wood was the heads of thirty Late Foundation Establishment Stage demonic Cultivators.

Its value was also exceptionally high among Tier 3 treasures.

However, upon seeing a hundred-meter-long section of crimson Spiritual Wood in his Storage Pouch, Lin Shiming understood why it required the heads of thirty Late Foundation Establishment Stage demonic Cultivators.

Nevertheless, even if he could refine eighty-one formation swords to form the Grand Purple Wood Mysterious Sky Sword Formation, he wasn't particularly excited at this moment, as the grotto-heaven pearl was not yet in his possession.

Only when the grotto-heaven pearl was in hand, and he had a Grotto-heaven World, could he transplant the Little Divine Tree and Wood Demon into the Grotto-heaven World. Then, he wouldn't fear inquiries about his Storage Pouch.

For this, he secretly gritted his teeth.

During the next demonic Cultivator attack, he must expose some of his strength and kill enough Early Foundation Establishment Stage Cultivators in one go.

Leaving the Treasure Pavilion, Lin Shiming headed directly towards an Artifact Refining pavilion in Tianhe City. This Artifact Refining pavilion was named Profound Green Artifact Refining Pavilion, and as its name suggested, it was an Artifact Refining pavilion opened by the Disciple of Danqi Peak (Pill and Artifact Peak) of the Qingxuan Sect.

Tier 3 Spiritual Wood naturally needed to be refined into sword formation prototypes, and his Artifact Refining skill could only refine Tier 2 Low Grade Magical Artifacts, let alone Tier 3 Magical Artifacts.

This Artifact Refining pavilion was also recommended by Xie An. It must be said that his Senior Brother had greatly helped the Lin family.

The Profound Green Artifact Refining Pavilion was only a two-story building, indicating that the Artifact Refining pavilion could only refine Foundation Establishment Magical Artifacts.

Upon entering, one could see two Cultivators sitting opposite each other, one holding a Secret Manual and examining it. Neither Cultivator was old, but both were Foundation Establishment Middle Stage Cultivators.

"May I ask if you two are Great Masters Lin Xuan and Xu Qing?"

Seeing Lin Shiming enter, the two Cultivators put down their books and sat upright, looking at Lin Shiming.

"Yes, but you can only choose one of the two Artifact Refiners, Fellow Daoist, just choose!"

"Yes, I am far superior in Artifact Refining to the one next to me. I think you should know how to choose!" The two spoke one after another, instantly filled with a strong sense of rivalry.

Lin Shiming finally understood why, when he asked Xie An where to refine artifacts quickly and affordably, the latter's expression after recommending the Artifact Refining pavilion was as it was.

Now that he thought about it, he had already anticipated this situation.

However, this also made Lin Shiming feel novel, and he also estimated that the Artifact Refining fees would be lower, as this was competition within the same shop!

"Great Masters, Lin wants to obtain the Magical Artifacts quickly, so please work together!" Lin Shiming replied, then saw their expressions turn cold, and continued with a smile:

"Don't worry, Spirit Stones and Materials are not a problem!"

"Fellow Daoist, you are mistaken. Both of our strengths are top-tier Artifact Refining strengths among the Qingxuan Sect Disciples. You can only choose one."

"Besides, can you really produce so many Spiritual Materials?" The two spoke one after another again.

Lin Shiming said nothing, took out the Storage Pouch containing the Yan Yang wood, and then took out thirty jin of qingming iron.

Both of these Materials were top-tier Materials for refining Flying Swords.

"This..." Xu Qing was instantly stunned when he saw so many Artifact Refining Materials. He had never expected that Lin Shiming, an Early Foundation Establishment Stage Cultivator, could produce Spiritual Materials worth millions of Spirit Stones.

"Alright, Xu Qing, this time, let's have a good competition!" Lin Xuan, after being stunned, instantly agreed.
