Nether Pool

"What's so special about this?" Lin Mu said with a sneer.

He moved swiftly, appearing before the Toad, his long sword flashing in his hand.

Sizzle!

A series of whooshing sounds rang out as wounds appeared on the Toad's body, its face contorted in pain.

Its eyes were fixed on Lin Mu; it hadn't expected this human to have such methods.

Normally, Netherworld Creatures are invincible in the face of living beings.

The human before him was an anomaly.

"Still not convinced?" Lin Mu sneered as he plunged his longsword into its skin, the entire blade disappearing into its body.

The Toad let out a painful scream, and its body trembled uncontrollably.

"What... what do you want to do?" The Toad seemed a little scared.

After all, Netherworld Creatures are different from living beings; once they die, they disappear completely.

"What I want to do? Don't you know?" Lin Mu said coldly.

"I can become your Contract object and obey your commands!" the Toad said.

"You don't deserve it!" Lin Mu said coldly.

"I don't need Contract clients like you, I only need slaves!"

The Toad's expression changed drastically, and it immediately shouted, "I am the Yellow Spring Toad, Third Grade being in the Netherworld!"

Lin Mu was slightly taken aback. "Third Grade? What does that mean?"

"We Netherworld Creatures have a clear ranking system, from one to nine ranks, with the first rank being the lowest and the ninth rank being the highest!"

"However, even a first-grade Netherworld Creatures can cause fatal damage to the living beings of this world!" said the Yellow Spring Toad.

Lin Mu nodded slightly.

He knew very well that the Netherworld Creatures were quite special.

Without special means, it is impossible to harm it.

More importantly, they can directly attack the Divine Soul, causing great harm to martial artists and Demon.

"Are there any restrictions on you Netherworld Creatures?" Lin Mu asked.

"Yes, we cannot stay in this world for long. Even if we sign Contract with you, we can only attach ourselves to you and lend you some of our power temporarily!" the Yellow Spring Toad explained.

Lin Mu nodded slightly; he knew very well that without any restrictions...

This world has long been swallowed up by the Netherworld.

"Then what should I do if I want to Contract a higher-level Netherworld Creatures?" Lin Mu asked.

"Impossible! You yourself are only at the Third Order. It's simply impossible for you to find Netherworld Creatures stronger than me!"

"The Netherworld Creatures are all very arrogant!" said the Yellow Spring Toad.

Lin Mu's face showed a hint of thought as he smiled and said, "If you can help me Contract with a high-level creature, I'll release you! You don't want to become my slave, do you?"

There was a hint of resentment in the eyes of the Yellow Spring Toad, but its life was now in Lin Mu's hands, so it dared not act rashly.

"There is a way, but it's quite risky!" said the Yellow Spring Toad. "There are many high-level young creatures in the Netherworld. If we can form Contract with them before they grow up, we can meet your requirements once they do!"

"Is there any way to find these creatures?" Lin Mu asked.

A sly glint flashed in the eyes of the Yellow Spring Toad, and it immediately said, "No need for such trouble!"

"Actually, some high-level beings also hope to sign Contract with humans, provided you have the ability to do so!"

Lin Mu asked, puzzled, "What do you mean?"

"It's very simple. Back then, there was a very powerful human who established a rule in the Netherworld: anyone who could stay in the Nether Pool for three days would be considered to have gained his approval and would surely be able to rule the Netherworld in the future!"

"Many higher-level beings believe in this rumor because that human did many incredible things back then!"

"The current Lord of the Underworld River the Underworld River was once under his command. You should know that before following him, it was just a second-grade Little Shrimp, but now it is a rare ninth-grade powerhouse in the Netherworld!" Yellow Spring Toad explained.

There was a hint of thought in Lin Mu's eyes.

If the Yellow Spring Toad wasn't lying, then this person is very likely the Nether Emperor.

Lin Mu looked at Black Saber King: "Are you aware of this?"

"The teacher did leave behind some methods in the Netherworld, but..." Black Saber King said with a hint of helplessness, "So many years have passed, and those methods are not coercive, so even if they succeed, it doesn't mean that any living being would be willing to follow. Moreover, it's very dangerous, after all, humans in that era were much stronger than they are now!"

"The challenges set are not so easy to overcome!"

Lin Mu nodded slightly, as long as it's true.

Having access to the system, he has absolute confidence in himself.

He was very confident that he could complete the challenge as long as it was feasible.

"Alright then!" Lin Mu looked at the Yellow Spring Toad: "Lead the way, I'm going to take a stroll around the Nether Pool!"

"No problem!" said the Yellow Spring Toad.

"But before that, we still need to set some restrictions on you!" Lin Mu said.

He looked at Black Saber King: "Is there any way?"

"You haven't yet Contract with Netherworld Creatures, so you can't directly enslave it. However, the Netherworld has Reincarnation System. As long as it swears an oath to the Nether God, it cannot easily break its vow!" Black Saber King explained.

Lin Mu nodded slightly, staring at the Yellow Spring Toad: "Do as he says!"

"Yes!" The Yellow Spring Toad nodded slightly, then swore an oath to the Netherworld: "I, the Yellow Spring Toad, swear that I am willing to lead Lin Mu to the Nether Pool and guarantee that I will not harm him!"

"Also, you are not allowed to leave until I complete the Nether Pool Challenge!" Lin Mu said.

"He is not allowed to leave until he has completed the Nether Pool Challenge!" said the Yellow Spring Toad.

As his words fell, it was as if an invisible Karmic Force had fallen upon him, and his soul seemed to be bound by shackles.

Lin Mu's eyes showed a hint of surprise; he hadn't expected the Netherworld to be so magical.

"Alright! Let's go check out the Nether Pool!" Lin Mu said.

"Be very careful, that place is very dangerous!" Black Saber King warned.

"Don't worry! I don't do things I'm not sure I can do!" Lin Mu said.

Black Saber King nodded slightly.

He knew that Lin Mu was no ordinary person and was naturally unwilling to Contract with an ordinary Netherworld Creatures.

In truth, he is the one who has a hard time.

Back then, he hadn't even managed to Contract with such Netherworld Creatures.

In the end, they could only sign a contract with a Fifth-Rank Netherworld Creature.

You could die at its hands if you're not careful.

Lin Mu followed the Yellow Spring Toad into the Netherworld once again.

Because the Yellow Spring Toad led the way, Lin Mu's Divine Soul attached to it increased, with almost half of Divine Soul entering the Netherworld.

Just like Netherworld Creatures coming into the real world, they must have a medium.

The stronger the medium, the greater the power it can generate!
