I let you have children and you lead seven sinful girls to rebel?

"You damned Chen Xuan, would it kill you to beg me for a second?!"

Dugu Rou rolled her eyes, realizing that Chen Xuan, with his straight-laced personality, would never back down or beg her.

Finally, she said it to herself.

The source of the Yellow Springs is divided into two springs: the Yin Spring and the Yang Spring.

The Yang Eye is the spring that they are currently seeing, from which clear water flows. As for what is inside the spring, she has no idea.

Meanwhile, in another location, liquid also flows out of the Yin Eye, but it is not water; instead, it is a thick, yellow liquid with a strong corrosive effect.

If the body of a Great Emperor or even a Quasi-Supreme expert falls into this thick yellow liquid, even their bones will be melted into dust.

Therefore, the yellow Yellow Spring water they saw on the shore, and the Yellow Spring water flowing through all the heavens and myriad worlds, are actually water resulting from the fusion of two liquids flowing from two springs at the source of the Yellow Spring.

The Yellow Springs liquid of the Yin Eye can corrode all the laws of the world. Even if a Quasi-Supreme uses the laws to protect their body, it will be corroded, thus damaging their physical body.

A single drop of the Yellow Springs liquid can cause flesh to rot and wounds to fail to heal.

Therefore, apart from the Supreme Being, no one can approach the Yin Eye of the Underworld.

It is said that the Yin Eye of the Underworld is also guarded by a supreme-level monster, which does not allow anyone to approach it.

Some say that the thick, yellow liquid flowing from the underworld's eye is the decomposition of a person's corpse.

Inside the Yin Eye of the Underworld is a tomb, where a supreme and terrifying being is buried. He died for some unknown reason, and his corpse became infected, the resulting putrefied fluids polluting the entire source of the Underworld.

If it weren't for that yellowish liquid from the corpses, this place wouldn't be called the Yellow Springs, but rather the Holy Spring.

After all, the Yellow Springs also has another name: the Holy Water of the Yellow Springs.

Therefore, many people speculate that the Holy Water of the Underworld is actually water from two separate springs.

The Yellow Springs are the pus flowing from the Yin Eyes, while the Holy Water is the clear water that Chen Xuan and the others could see with their naked eyes. This water is so clean that it can be drunk directly!

However, because the holy water was polluted by the Yellow Springs, the word "holy" was removed, and it became Yellow Springs Water.

The river that flows through all the heavens and myriad realms is also called the River of the Underworld, not the Sacred River of the Underworld.

After listening to Dugu Rou's explanation of her self-talk, Chen Xuan looked thoughtful.

It turns out that the legend that the Yellow Springs Water is corpse water is not unfounded, but rather a genuine source of information.

"Who on earth buried their grave here, polluting the entire water source?"

Chen Xuan began to ponder.

The River of the Underworld has existed since the beginning of the Boundary Sea Era.

In other words, this so-called corpse that is festering and oozing fluid is a creature even more ancient than the Boundary Sea Era.

It's important to understand that the Boundary Sea Era is different from the Savage Era and the Mythical Era, which only lasted for 1.296 billion years.

The two eras combined only amount to approximately 2.6 billion years.

However, the Boundary Sea Era, from its inception to its end, lasted a full ten billion years!

So far, Chen Xuan has only heard of one being that is even older than the Boundary Sea Era: the ancestor of the Angel Race, who is also the owner of the Angel Heart within Dugu Rou's body!

Even the Desolate Celestial Venerable only came to the myriad realms during the middle of the Boundary Sea Era.

Now, another being even older than the Boundary Sea Era has appeared: the master of the Yellow Spring Yin Spring!

Of course, all of this was just something Dugu Rou had heard from other places.

Whether it's true, whether the spring is the tomb of some ancient creature, and whether the yellow liquid flowing out is its decaying corpse, remains to be seen.

Seeing is believing!

"What are you looking at? Can we come in?"

Seeing Chen Xuan bending over and staring at the spring, Dugu Rou couldn't help but speak up.

"It should be fine, right?"

Chen Xuan said, but he did not go in immediately. Instead, he first let the World Tree extend a branch out.

He stretched a branch into the spring to test the way, and only after confirming that there was no danger did he prepare to jump in.

"I'll go in first, you follow me."

After saying that, he plunged into the spring in a dragon-like motion.

There was a force pushing outward from the spring, seemingly trying to squeeze Chen Xuan out. Fortunately, this force was not very strong, and Chen Xuan moved against the current, darting through the spring like a nimble fish.

Dugu Rou followed closely behind.

Although the passage through the spring was pitch black and nothing could be seen, fortunately, it did not suppress the extension of divine sense.

Therefore, they do not need eyes to see; they can scan everything around them with their divine senses alone.

The spring's passage was very long; Chen Xuan and his companions swam for almost half a day and still hadn't reached the bottom.

"Chen Xuan, if we swim any further, will we reach the Earth's core?"

Dugu Rou couldn't help but complain.

The main problem is that the passage to this spring is only one meter wide, so they have to keep their heads down and feet up at all times.

“I’m not sure either. Let me swim a little longer and see. If it’s really not working, you can go back first, and I’ll swim to the bottom and then come up to get you.”

Chen Xuan transmitted his voice.

"Tch, you think you can shake me off? No way." Dugu Rou refused to back down and followed closely behind like a shadow.

Well, since she's said that, what else could Chen Xuan say but to continue?

The two continued swimming downstream for nearly an hour.

"It seems like we're almost at the end!"

Suddenly, Chen Xuan stopped, his whole body stiffening in surprise.

Because ahead, the narrow passage, only one meter wide, had become much wider.

Furthermore, the direction is no longer downwards, but forwards.

Chen Xuan and his companions landed on the ground, and a dark tunnel appeared in front of them.

The tunnel was pitch black, and you couldn't see the end of it at a glance.

"Chen Xuan, are you cold?"

Dugu Rou suddenly transmitted her voice.

Chen Xuan turned his head and found her shivering from the cold.

"A little. Let's use divine fire to protect ourselves; maybe that will make us feel better."

Chen Xuan nodded. In fact, the deeper you go, the lower the temperature gets.

Strangely, the water wasn't cold; it was actually a bit warm.

But the environment here made their bodies feel an uncontrollable, bone-chilling cold.

"Why don't you wait for me here?" Chen Xuan suggested.

"No, I have to watch over you!" Dugu Rou shook her head. "What if you accidentally die in there? With me here, I can protect you."

"Can't you wish me something good?" Chen Xuan bent his index and middle fingers and gave Dugu Rou a sharp rap on the head.

"You dare hit me!"

Dugu Rou pounced on her immediately.
