"It worked!"

Lin Mo opened his eyes, his gaze shining brightly.

Indeed, it worked. The 'Black Snake Totem' on his back genuinely had a unique control ability over Netherworld Power. Not only could it quickly purify the vicious aura within, but it also made the Nether Energy incredibly pure, doubling the Nether Energy contained within ordinary Netherworld Stones.

Thinking of this, Lin Mo held out his palm, and streams of purple energy flowed back through his meridians. The palm immediately burst with purple brilliance, and moments later, twenty walnut-sized Netherworld Stones appeared on his palm. These purple stones emitted a pure and captivating Netherworld Power.

"According to Brother Xue, refining a single Nether Origin Stone is equivalent to ten ordinary Netherworld Stones, but after purification with the 'Black Snake Totem', it can actually produce twenty ordinary Netherworld Stones."

With this situation, I only need to slay fifty Star System-level early-stage Barbaric Beasts to harvest a thousand Netherworld Stones. Absorbing these Netherworld Stones should allow me to step into the ranks of a Second Seal Nether Pattern Master. With the strength of a Second Seal Nether Pattern Master combined with my own power, I would be able to kill Li Ling and the Great Elder of the Netherworld Sect if encountered alone.

However, wanting to kill a Star System-level Barbaric Beast in this area is much more difficult than outside. Although my power is not suppressed in this gray space, the beasts here are exceptionally fierce and violent, also unaffected by the peculiar force of the space region.

The main issue is that the beasts do not operate alone. Once a fight breaks out, it is easy to attract surrounding beasts for a siege...

Just observing how difficult it is for Xue Chen and the others to handle two beasts can imagine how difficult it is to slay the beasts here.

"There is another way, directly exchanging for Nether Origin Stones from those people... There are many people at this gathering point, and there should be those who have hunted beasts for Nether Origin Stones."

Thinking of this, Lin Mo dispersed the Array, placed the Netherworld Stones into his Space Ring, and then, carrying the Xuanyuan Sword, walked out of the small house. The wide street didn't have much traffic, many people gathered together, choosing a secluded place to quietly cultivate, and those walking on the streets mostly remained silent, each maintaining a vigilant heart.

"Should I just shout here to buy Nether Origin Stones?" Lin Mo frowned, glancing around, and suddenly saw some people quickly walking down the street ahead.

"I wonder if we can exchange for any treasures this time!"

"Came to this space for some unknown reason, the beasts here are extraordinarily mighty, I need to exchange for a defensive-type treasure!"

These people whispered among friends, speaking quietly, but Lin Mo's senses were extremely sharp, naturally hearing clearly, immediately understanding that these cultivators gathered in the city seemed to be trading treasures together.

"Maybe I can gain some here!" Lin Mo quickly followed the group.

After a few minutes, they arrived at a wide plaza where over a thousand people had already gathered. These people surrounded together, seemingly discussing the trade of treasures. In such a Secret Realm Space, everyone wants to enhance their strength, naturally forming such a place for transactions, each taking what they need.

"Vajra Ape Transformation, a Heaven Rank Intermediate Defense Technique, I need an offensive Star Sea Level treasure."

"Heavenly Gang Earth Evil Saber, a Star Sea Level High Grade Treasure, I need a few Heaven Rank Healing Holy Medicine..."

Voices spread from within the crowd. Lin Mo did not rush to purchase Nether Origin Stones, instead casually wandering about. Most of the trades here were bartering, no one was trading with soul coins, as soul coins have no use here. Only treasures can quickly enhance one's strength, providing enough self-protection and the ability to contest for treasures.

After a round, Lin Mo roughly gauged the crowd. Among them, there should be disciples from the Hexagram Sect, and some emitted a mixed aura, indicating small factions entered this space region. Some even wore red-white interwoven outfits, each exuding arrogance.

"People from the Five Primus Sect?" Lin Mo squinted slightly. He had promised Zhou Xinyue to exterminate the Five Primus Sect to avenge her master.

But given the current situation, with various forces entrenched, and so many eyes around, it wasn't the right time to strike. Moreover, the Sect Master of Five Primus Sect reached a half-step Star Domain Level. If he truly intended to eliminate the Five Primus Sect...he would need to reach the Star System Level Early Stage at least to have enough confidence.

After the round, Lin Mo stood at a secluded spot in the plaza, then flipped his hand, revealing several Netherworld Stones with pure Netherworld Power upon his hand, drawing much attention, and soon surrounded by many.

"These are Netherworld Stones, incredibly significant for a Netherworld Pattern Master. Whether used for cultivation or array setup, they hold great value. Let's get to the point; I want to exchange these Netherworld Stones for your Nether Origin Stones. The Nether Origin Stone embodies a violent, vicious beast aura, difficult to absorb... but these Netherworld Stones, with their pure Netherworld Power, are of high quality. I wish to exchange five Netherworld Stones for one Nether Origin Stone," Lin Mo stated in a loud voice.

The crowd erupted with astonishment as largely everyone was aware of Netherworld Pattern Masters' affairs, and Netherworld Stones were vital to them. Even if one wasn't a Netherworld Pattern Master, absorbing Netherworld Power could increase cultivation, and they could power arrays and magic treasures like an energy source.

Nether Origin Stone, a treasure within the beasts of this space, could be refined into ten Netherworld Stones when purified. But refining takes a considerable amount of time and True Yuan... thus, Lin Mo's pure Netherworld Stones, exchanging five for one Nether Origin Stone, was an acceptable deal.

"What are you doing with the Nether Origin Stones?" someone asked.

"That's my business, but if any of you have Nether Origin Stones, you may exchange them!" Lin Mo replied calmly.

Currently, he has twenty pure Netherworld Stones, capable of exchanging for four Nether Origin Stones. Once he refines them, it shouldn't take long to accumulate a thousand Netherworld Stones, formally entering the ranks of a Second Seal Nether Pattern Master.

"I want to exchange..." A bearded man stood out, clad in a vest, a massive dark giant axe on his back towering over him, and his mere presence made those around him shudder. He then handed a Nether Origin Stone filled with Evil Qi to Lin Mo. 𝘧𝓇𝑒𝑒𝑤ℯ𝑏𝓃𝘰𝑣ℯ𝘭.𝘤ℴ𝘮

Upon the bearded man's exchange, three more people came forth to trade for Netherworld Stones. After all, the Nether Origin Stones were useless to them without a purification method, better to trade for pure Netherworld Stones that could absorb Netherworld Power.

"If any of you still have Nether Origin Stones, I'll wait here tomorrow with more pure Netherworld Stones." Lin Mo cupped his fist in salute.

Just as he stored away the Nether Origin Stones and prepared to continue refining pure Netherworld Stones, a group dressed in black-red outfits suddenly blocked his way. The leader was a young man with a sinister expression, his eyes slightly sunken, giving an ominous vibe.

"Oh, Netherworld Stones..." The leader's eyes glinted with a cunning hue, the corners of his mouth curving into a sinister arc.
