Two months later, the figures of Han Li and Shi Chuankong appeared in the sky above a vast lake.

Calling it a lake, the surface was boundless, the waves surged, and bursts of water mist rose from time to time, making it no different from the sea.

"This lake is called Thousand Wave Lake, and Heihe Shangren resides in the Water Palace deep at the bottom of the lake. Fellow Daoist Li, in my opinion, we should first try courtesy before resorting to force," Shi Chuankong said, glancing at Han Li.

"Fellow Daoist Shi, rest assured. The other party is a Grand Luo existence and an ally of the Third Prince. I will not act rashly," Han Li said, his expression having returned to calm as he nodded.

Seeing this, Shi Chuankong secretly breathed a sigh of relief.

"Speaking of which, this place is already considered a more remote part of the Blackwater Domain. After passing this lake, it will be the Black Barbaric Domain, right?" Han Li suddenly said.

"That's right," Shi Chuankong said, startled by the words, then sighed.

The Accumulation Scale Void Realm was in the Black Barbaric Domain, not far from here.

Han Li nodded slowly but said nothing.

The two then flew into the lake, heading downwards.

Thousand Wave Lake was extremely deep. The two descended tens of thousands of feet, yet there was still no sign of reaching the bottom.

At this moment, huge water pressure was pressing in from all directions, making even Han Li feel somewhat uncomfortable.

Shi Chuankong opened his mouth and spat out a water-blue round bead.

A soft blue light emanated from the bead, forming a huge blue light sphere that enveloped the two, and the surrounding pressure immediately disappeared.

The blue light sphere enveloped the two and continued to dive forward. After another few thousand feet, they finally reached the bottom of the lake.

However, the lake bottom was undulating, like a continuous mountain range.

The ground was cracked with huge fissures, infinitely deep, seemingly connecting to the endless Netherworld.

Shi Chuankong urged the blue light sphere to drill into a huge fissure, continuing downwards.

"Fellow Daoist Shi seems very familiar with this place. Have you been here before?" Han Li asked, seeing Shi Chuankong acting as if he knew the way.

"No. It's just that Third Brother formed an alliance with Heihe Shangren back then, and I contributed to it. I once carefully investigated the situation here at Heihe Shangren's place," Shi Chuankong said with a smile.

"I see," Han Li said, his eyes flickering, but he did not ask further.

The water quality in the underground fissures of this lake was slowly becoming somewhat different from the surface. It was heavier and more viscous, and the deeper it went, the darker the color, resembling heavy water.

The surrounding light was dark, so dark one could not see their fingers, and even with the eyesight of the two, they could not see very far.

This time, they did not descend for long before a bright light appeared before them.

They saw that the fissure space ahead suddenly became larger, and a huge underground cave appeared.

In the center of the cave, a huge island with a radius of ten thousand acres was suspended.

This entire island was not ordinary stone or sand but a whole piece of black crystal, on which pavilions and towers were carved, forming a continuous palace complex.

On the largest palace hung a plaque dozens of feet in size, with the four characters "Black River Water Palace" written on it.

The entire island bloomed with bursts of water light. Although it was black, it gave a crystal-clear feeling, making the place look like an underwater crystal palace, extremely magnificent. The island was surrounded by a huge transparent black light罩, isolating the surrounding lake water.

On the black light罩, dense forbidden runes could be vaguely seen, emitting traces of terrifying forbidden fluctuations.

Han Li had no doubt that if someone forcibly attacked, the restrictions on the black light罩 would erupt, even a Taiyi Realm cultivator could be instantly killed.

"Finally, we've arrived. This entire island is a huge piece of Taiyin water jade, refined by Heihe Shangren with supernatural powers for who knows how many years. Now the entire island can be considered a giant magic treasure, which is very powerful. So unless absolutely necessary, we should not conflict with it," Shi Chuankong said in a low voice.

Han Li looked at the huge island in front of him without speaking, but a hint of determination flashed in the depths of his eyes.

Seeing this, Shi Chuankong sighed. Knowing that further persuasion would be useless, he said nothing, turned his hand, took out a blue jade token, muttered a few words, and waved it out.

The jade token turned into a blue light, flashed through the black light罩, and disappeared into it.

After a moment, a slightly wary female voice came from the island: "Which fellow Daoist is visiting the Black River Water Palace?"

"I am Shi Chuankong, here to pay respects to Heihe Shangren," Shi Chuankong stepped forward, took out the purple token, and said with a smile, cupping his hands.

"So it is the Thirteenth Highness. I apologize for not welcoming you from afar," the woman's voice paused slightly before saying.

As soon as the words fell, a vortex-shaped dazzling black light emerged on the black light罩 in front of Han Li and Shi Chuankong, then separated to both sides, revealing a channel several feet in size.

Han Li secretly thought that the title of prince was indeed useful, and at the same time, he was even more grateful to Shi Chuankong. If it weren't for his company, given that person's caution just now, it might have been difficult to enter this Black River Water Palace.

He and Shi Chuankong exchanged a look and flew into the channel.

As soon as the two bodies flew into it, a series of black lights suddenly emerged, enveloping the two like a surging tide.

Han Li frowned slightly but did not resist.

His eyes suddenly blurred, and the next moment he appeared in a hall.

The hall was quite large. The walls and floor were crystal black. Even the seats and other objects in the hall were closely connected to the ground, and were carved. They were exquisite and harmonious, without the slightest disharmony.

A sound of footsteps came from the hall, and a beautiful woman wearing a light blue gold-threaded feather coat, with high cloud temples and three gold-carved phoenix hairpins inserted in her hair, walked out, followed by four respectful maids.

This woman looked to be in her thirties, with fair skin and a beautiful appearance, but her eyebrows were straight, giving her a sharp feeling.

Han Li glanced at her, and this woman's cultivation was not weak, having reached the early stage of the Taiyi Realm. Judging from her demeanor, she seemed to be an important figure in this Black River Water Palace.

"Thirteenth Prince, your Highness, has arrived. I have failed to greet you with the courtesy due to a prince. Please forgive me," the feather-coated beauty said, performing a salute. Her voice was the same as the one that had transmitted the message remotely.

"Madam is too polite. We arrived too suddenly today," Shi Chuankong said with a smile.

The feather-coated beauty looked at Han Li, and her stern eyebrows furrowed slightly, but she said nothing.

"Fellow Daoist Li, this is Madam Ju, Heihe Senior's Dao Companion. This is Fellow Daoist Li. Although he comes from the Immortal Domain, he is a close friend of Shi. Fellow Daoist Li has great supernatural powers, and the Emperor also admires him," Shi Chuankong said, observing the expressions and introducing both sides.

"Madam Ju, Li greets you," Han Li said, his heart moved, and he cupped his hands.

Hearing this, Madam Ju looked at Han Li again, her attitude softened a little, and she slightly bowed, considering it a return of the salute.

"I wonder, Thirteenth Prince, Your Highness, what brings you to my Black River Water Palace? If there is anything you wish to impart, I am all ears,” Madam Ju said, inviting the two to sit down and ordering the maids behind her to serve tea and fruits.

"I would not dare to impart anything. Shi has come today with a matter to ask Heihe Senior. I wonder if Heihe Senior is in the palace?" Shi Chuankong said.

"Ah, Your Highness has come at a bad time. My husband has been in closed-door cultivation for many years in order to cultivate a great magic. I am afraid he cannot come out to meet Your Highness," Madam Ju said with a proud expression on her face.

Hearing this, Han Li secretly breathed a sigh of relief.

"Is that so? That really is a shame." Shi Chuankong said, glancing at Han Li out of the corner of his eye.

"Before my husband entered closed-door cultivation, he asked me to manage the various affairs of the Black River Water Palace. I wonder, what is the matter that Your Highness has come to my husband for? As long as it is not too big a matter, it is the same if you tell me," Madam Ju said, gathering the hair beside her ear, with a smile on her face.

Although she tried to hide it, her expression still revealed a hint of complacency.

"Haha, speaking of which, it is indeed not a big deal. I heard that the Black River Water Palace recruited a lower realm ascender named Ziling over a hundred years ago. I wonder if there is such a thing?" Shi Chuankong said with a smile, his eyes turned.

Hearing this, the smile on Madam Ju's face disappeared instantly, and a layer of frost hung on her snow-white face. A look of jealousy appeared in her eyes, and at the same time, a sharp, chilling cold light flashed through her eyes.

However, those changes only happened in an instant. The next moment, Madam Ju's expression returned to calm, and she said: "Oh, there is such a person, but I wonder why Thirteenth Prince, Your Highness, asked about this person?"

Although Madam Ju's expression changes only passed in a flash, both Han Li and Shi Chuankong saw it.

Han Li's heart sank, but he did not open his mouth.

"Actually, it's not a big deal. That Ziling and Fellow Daoist Li were friends who knew each other in the lower realm. Fellow Daoist Li heard that she ascended to the Holy Region, and came to visit today. I wonder if Madam can ask Ziling to come out and let them meet?" Shi Chuankong said solemnly.

"Hehe, friends? I'm afraid they are lovers! A vixen is a vixen. She hooks up with men wherever she goes!" Madam Ju glanced at Han Li, sneered.

"Ziling has just ascended to the Holy Region and is not familiar with everything here. If she has offended you in any way, I am willing to apologize on her behalf," Han Li said, his mind racing, and he stood up and cupped his hands.

"Offended... Hmph!" Madam Ju snorted coldly but did not continue.

"In order to appease Madam's resentment, I have a few decent materials here. Please accept them with a smile," Han Li said, his eyes turned, and he raised his hand and waved.

A green glow flew out of his hand and brushed across the table next to him.

Four things suddenly appeared on the table: a small blue flag, a purple-black seal, a blue ice crystal, and a piece of black dead wood.

The small blue flag and the purple-black seal were both magic weapons, and both were ranked magic treasures. The blue ice crystal and the black dead wood were also materials containing the power of laws. Each one emitted extremely huge power of laws, vaguely above the two magic weapons.

These magic weapon materials were all found in Zhao Gu Zhenren's storage magic artifact. Even Shi Chuankong was very envious when he saw them.

When Madam Ju saw these things, her eyes also moved, but then she snorted coldly, looked up at the sky, and did not even look at those things.

Seeing this, Han Li's face sank.

"Cough, Madam Ju, no matter what, can you please let them meet for my sake?" Shi Chuankong coughed lightly and said.
