He Lin settled down in Rongcheng and conducted reconnaissance every night. After a week, he finally found a clue.

"It turned out to be the ghost messenger who sent pure soul power to these monsters!"

Monsters eat humans, primarily their souls. Ordinary animals can be used to supplement their meat needs. Alternatively, they can simply absorb the monster's energy without eating meat.

However, soul power cannot be replenished by eating meat or breathing in demonic energy, but only by eating human souls.

Monsters may not be born with spirits like humans, but they need to constantly eat human souls to maintain their intelligence!

"Moreover, not all monsters have the pure soul power provided by the ghost messenger. For example, the pig monster in Gao Village and the water monster in the river! They don't have ghost messengers to provide soul power!"

"So, the pig monster is malnourished and the water monster is cannibalistic."

"That pig demon is also extraordinary. He can cultivate to the level of a demon general without eating humans, and he can still maintain his sanity. He is truly extraordinary!"

After understanding the situation here, He Lin chose to follow these ghost officials to take a look at the underworld.

"This world is truly interesting. They've even managed the otherworld and established the underworld! It's true that every transcendental world and every cultivation system has something truly eye-opening!"

After reaching the fusion stage, the whole body becomes one, forming its own world, without the distinction between body and soul. The new body also contains all the original attributes, so it can naturally enter the underworld.

"Is this the underworld? It's not exactly what I thought! It's indeed centered around the inner world, but it's a demiplane formed by a powerful magical instrument. Is the core of the magical instrument this path of reincarnation?"

Herlin flew calmly past these ghosts, but none of them could see him, or should I say, discovered him, because if he was blocking the way in front of them, they would subconsciously avoid him, but they completely ignored Herlin's existence.

Standing in front of the Samsara Path, looking at it, no, it should be called the Samsara Pearl. After communicating, I understood the truth.

"One of her powerful magical instruments can actually devour the other world and evolve into its own world! Rather than calling it the underworld, it's more like a magical instrument space within the reincarnation bead that can accommodate souls."

"The function of the Wheel of Reincarnation is very simple. It absorbs souls and separates the true spirit and soul force within them. The true spirit returns to the origin of the world, while the soul force returns to the practitioners of this world. It's truly a powerful magical instrument! And the person who created this magical instrument, if I'm not mistaken, is another descendant! Judging by the age of this Wheel of Reincarnation, it must have been refined by a descendant thirty thousand years ago. He should be from the Origin Realm like me, one of those six people! He's considered one of my predecessors!"

"So, it seems that this is the ancestor of the weapon refiners in this world! No, we should also include the world of cultivation. The two are twin worlds, and the cultivation systems of the two worlds are highly overlapping. Auxiliary professions can definitely learn from each other!"

No wonder there's no master of weapon refining in the world of cultivation? Yet, the art of weapon refining has developed so well. This is probably because when the Advent Ones were here, the two worlds were connected, and the cultivation systems of the two worlds were initially completed, which led to the importance of magic weapons in both cultivation systems!

This is evident from the fact that in the world of cultivation, people even use magical instruments as the foundation of a family.

Although this world has not been fully understood yet, the fact that the underworld is actually a complete space for magic tools shows the powerful role of magic tools in this world.

He Lin was delighted to see the prey and immediately began to analyze the principle of the reincarnation bead.

Analysis is Herlin's specialty. Three years later, Herlin completed the analysis of the Samsara Pearl.

"I see. The Samsara Pearl itself is a growing spatial artifact with the ability to devour. Then, it parasitized the inner world, slowly devouring it, and evolving into the underworld! After devouring the inner world, it even began to devour the material world!"

"What a great foreshadowing!"

Herlin now felt the difference between him, the newcomer, and those veterans!

He's still in the mission stage, but others have already started planning for the future?!

"This bead of reincarnation must belong to one of the six people, and one of the top-ranked ones. He will come back to retrieve this bead when he returns!"

Shaking his head, He Lin left the underworld! He Lin had no intention of seizing the reincarnation bead. He was just excited to find out its principles and supplement the database in his consciousness chip.

"Something this crucial must have a back-up plan. It's not easy to seize! Otherwise, the people before me would have already taken it!"

Moreover, when he had the thought of seizing it, he immediately had a strong warning of danger. At their level, especially at the stage of cultivating consciousness, the premonition of danger is already very strong!

This was the first time there was such a strong danger warning, which surprised Herlin.

"As expected, we can't underestimate any of the adventers! None of those six people are simple!"

The Nine Extremes Formation had nine slots for descenders. I was the seventh, and there were six people ahead of me. These six had already begun descending into the Heavenly Dao Realm, and they had accumulated immense capital by then!

For example, the one who refined the Samsara Pearl. Completing the Heavenly Dao mission was just a side job. It was estimated that the other party's main purpose was to give birth to this Samsara Pearl.

Using the power of a hospital world to create a magical weapon, one can imagine how powerful this magical weapon is, and one can imagine how powerful the person who refined this magical weapon is!

He took one last look around the underworld and shook his head. These ignorant ghost officials! They were still vying for power and profit! They didn't realize that they were just cattle and sheep raised by the reincarnation pearls, ready to be slaughtered and devoured at any time!

He left the underworld without staying any longer. After thoroughly studying the Samsara Pearl, the underworld no longer held many secrets for him. Although he couldn't refine it, he could still make use of it.

"I think the people before me would have done the same if they had discovered it. After all, using it a little wouldn't harm the Samsara Pearl at all, and on the contrary, they would owe that person a favor. Neither the Samsara Pearl's spirit nor the senior who refined it would care. On the contrary, they would be happy to see it succeed."

According to my own investigation, in the past few hundred years, someone has used the Reincarnation Pearl to accomplish something.

"In the last few hundred years? He should be the ancestor of sword cultivation. I have a strong connection with this senior, huh?! The Sword Saint Li Qing from the previous sword world should be the incarnation of this senior! I didn't expect to meet him again this time!"

"Besides the ancestor of sword cultivation, there's also the ancestor of formation masters, who must also be a senior descender. Add to that the ancestor of weapon refinement, wow... these two twin worlds of cultivation and immortal Buddha are truly bustling!"
