186: Chapter 185 The Four Regions of the Boundary Sea

"Let's go."

Ye Xiu said nothing more.

Since Xing Mu wasn't worried, why should he be?

His primary concern right now was the fusion of his two cultivation methods; he couldn't afford to worry about anything else.

"That's the spirit."

A hint of a successful scheme's smile appeared within Xing Mu's double pupils.

It felt as if everything she had just said had been done intentionally.

Hum...

The River of Time manifested in the firmament.

Countless living beings looked up at the sky, wondering what was happening.

"Open..."

A light shout rang out.

The long river shook, and a rift was instantly torn open.

"Go."

The two did not linger, directly crossing through space to enter the River of Time.

"Xing Mu, you should not have come here."

Before they had even found their footing.

The Human Emperor had already descended from the source of the River of Time, his imperial Qi incredibly dense.

Even before he drew near.

Ye Xiu felt an extremely powerful pressure rushing toward him.

"What? Does my conduct require a washed-up Human Emperor like you to tell me what to do?" Xing Mu completely ignored the Human Emperor's words, pulling Ye Xiu directly toward the source of the River of Time.

"Uh..."

The Human Emperor stood there awkwardly.

Watching the two leave, he shook his head slightly and did not move to block them further.

"Xing Mu, the Boundary Sea is very chaotic. Too many people are watching the Main World. Remember... act with caution."

Following the Human Emperor's exhortation.

The two were already traveling upstream in the River of Time. In just a moment, they reached the source region of the river.

"That place... what is it?"

Ye Xiu looked at the world shining with immortal light, appearing like a grand era, and his heart shook.

Immortal power surged within his body.

As they drew closer, he could clearly sense that his own immortal power felt a great affinity for that world.

"The Immortal Realm. Like the endless Chaos, it is vast and boundless. Even for us, it would likely take quite a bit of time to travel through all its regions."

Xing Mu explained.

Then, as if thinking of something happy.

She spoke again: "There are many miraculous treasures in the Immortal Realm. How about we go play there for a few days first?"

Play?

Ye Xiu shook his head slightly. "Now is not the time for playing. We'll talk after I finish the Fengshan ceremony."

"Fengshan ceremony? Fine, it's a deal. Once you're done, I'll come find you. Heehee... there's a type of ancient Phoenix in the Immortal Realm that is said to bring auspiciousness. I want to catch one and raise it."

"Is the Boundary Sea right next to the Immortal Realm?"

Outside the River of Time.

To the left was the vast and boundless Immortal Realm, shrouded in hazy immortal light. To the right was the endless Domain, layered upon layer like an ocean—the Boundary Sea.

These layered Domains were incredibly broken, appearing like the Dead Realm, and their numbers were terrifyingly high.

"Yes, that is the Boundary Sea. Legend has it that on The Other Shore of the Boundary Sea, there lies the secret to becoming a Taboo Emperor. That old fellow Dong Huang really is a piece of work. Ye Xiu, do you think I should expel him from the Main World?"

Xing Mu didn't sound like she was joking.

Her pretty face was full of seriousness.

"Xing Mu, does the Imperial Court not know Dong Huang's secret either?"

"No. Dong Huang's father is an ancient existence who is rumored to have already reached The Other Shore of the Boundary Sea. Dong Huang followed his father's path to reach it as well."

"Then why did the Human Emperor block the calamity for Dong Huang?"

"Are you stupid? Didn't I tell you? Everything the Imperial Court does is a scheme for the Main World. The matter with Dong Huang was just a coincidence."

"Was it really a coincidence?"

Ye Xiu didn't believe that explanation.

Dong Huang was someone who had been to the Other Shore. Would the Imperial Court not be curious?

The inside story was likely something...

Only the Human Emperor knew. After all, Xing Mu hadn't even been born when the Imperial Court was first established.

She definitely hadn't participated in the events of that time.

However, given Xing Mu's status, she ought to be aware of the Imperial Court's deepest secrets.

That left only one explanation.

Only the Human Emperor was involved in matters related to Dong Huang. Perhaps there were things the Human Emperor hadn't even told the Blade Master and the others.

"Believe what you want."

Xing Mu didn't bother to explain further and was the first to fly into the Boundary Sea.

The Domains beneath their feet were deathly silent. These endless, continuous Domains rose and fell like tides under the influence of unknown storms.

The two were very fast.

A single step crossed tens of millions of Domains.

Yet for the Boundary Sea...

These tens of millions of Domains were but a single drop of water in the ocean.

After walking for a long time.

Ye Xiu finally asked in confusion, "Xing Mu, didn't you know the location of the soul-returning grass? Why does it feel like you're just searching aimlessly?"

"Tsk... the Boundary Sea is vast and boundless, and these Domains are layered one on top of the other. How could I still remember the exact location? Besides, the medicinal properties of the soul-returning grass are so specific that it's useless to me. Why would I keep it in mind?"

"Are you kidding me?"

"Are you snapping at me?"

"You..."

The two glared at each other, both looking exasperated.

"Fine, let's just look."

In the end, Ye Xiu was the first to pull back his anger.

He asked, "Is there any way to find it quickly?"

"The soul-returning grass is formed from the essence of a powerhouse after their death. In places where there are ripples from a great battle, there is a high chance it will manifest."

"Doesn't it need time to grow?"

"Naturally. It takes about a hundred thousand years or so to take shape. However, the soul-returning grass is sentient and usually grows at the Origin of a Domain, so it's very hard to find."

"You..."

Ye Xiu had completely lost his temper.

With Xing Mu, he felt like he had returned to those years past.

She could truly infuriate a person to death, yet you couldn't do a single thing about her.

"I'm just teasing you. For me, finding the soul-returning grass is as easy as lifting a finger." Seeing Ye Xiu's face darken, Xing Mu coughed lightly and explained.

"Then just find it already."

"What's the rush? Am I not explaining it to you? If you rush me again, I'm going back."

"Fine... Young Miss, when can we start looking?"

"Let me prepare myself."

"Prepare for what?"

"This scenery reminds me of something."

"..."

"Back then, I led the Imperial Court's iron cavalry all the way from the River of Time to the East of the Boundary Sea. After slaying several Immortal Kings in a row, I even sent a Nine Nether Immortal Venerable fleeing in panic..."

"And then?"

Ye Xiu spoke somewhat weakly.

He looked at the floating Domains and was surprised to find that some actually possessed the aura of living beings; clearly, civilizations existed there.

"And then... the world began to call me Venerable Mu."

Xing Mu looked proud, not looking like a Star Emperor at all, but rather like a wild girl who had just been let out of the house.

"Alright, enough nonsense. Why are there still living beings in this Boundary Sea?"

"Of course they exist. How could these endless Domains be nothing but dead worlds? In the explored areas of the Boundary Sea, it is divided into four regions. The region we are in is the East Region, also known as the Ancestral Domain."

"Ancestral Domain?"

"Yes. The Immortal Realm and the River of Time are the Ancestral World, so the East Region that encompasses this place is naturally the Ancestral Domain."

"What about the other regions?"

"If there's an East Region, the other regions are naturally the South, West, and North Regions."

Xing Mu finished, then added: "However, except for the East Region which has the boundary of the River of Time, the other three regions have no clear boundaries; there are only unknown areas."

"Unknown areas? Are they unexplored?"

"Naturally. Over countless ages, the areas of the other three regions should have grown quite a bit. I just don't know if the people from back then are still around."

A hint of nostalgia appeared in Xing Mu's eyes.

She seemed to think of something happy, and a slight smile appeared at the corners of her mouth.

"Now is not the time for reminiscing. Finding the soul-returning grass is the priority."

Ye Xiu spoke up to remind her.

He was truly afraid Xing Mu would go off to catch up with old friends, which would not only waste time but also risk exposing the secrets of the Main World.

After all, the aura of the Main World on Xing Mu was far too dense.

Even with his strength as a newly ascended Immortal Lord, he could clearly sense it.

If they encountered an Immortal King or an Immortal Venerable.

The secret of the Main World being devoured would definitely not be hidden.
