The Flame Demon Sea Monster practically drooled when it saw her; this woman was truly beautiful.

Zu An remained calm. This woman was beautiful, but she had no soul. Her expression was dull, and she was far inferior to Shang Liuyu.

The mermaid phantom looked at Shang Liuyu, and suddenly two beams of light shot out from her eyes, scanning her from head to toe before saying, "Mermaid royal bloodline confirmed, permission granted."

After saying this, the phantom returned to the mermaid statue on the wall.

The lines on the mermaid statue began to disperse and reconstruct, eventually forming a unique pattern.

The pattern seemed to resonate with the surrounding divine runes, and soon golden lines connected them, causing the entire wall to shine with brilliant golden light.

The Shadow Fiend and Kachir quickly retreated a distance.

A thought struck Zu'an: they seemed somewhat afraid of this light.

Unfortunately, the light did not last long and quickly went out. Then the wall slowly opened to both sides, revealing a huge and deep opening.

Shang Liuyu was taken aback. The wall had been sealed tightly, with no sign of it being able to be opened. He never expected there to be such a vast space behind it.

Kachir and the three demons both showed excited expressions: "It's done!"

With a wave of their hands, their respective men quickly ran ahead to scout the way. Before long, the men returned to report that no danger had been found ahead, and the demons' smiles grew even wider.

He then gestured for Zu'an to follow, and they went inside together.

Immediately, everyone's gaze fell on Shang Liuyu. After opening this door, she was no longer of any use. The others were all demons or evil spirits from hell, but this woman was a sea creature.

Zuan saw through their thoughts and whispered, "This place is too mysterious. We might need her again later."

The demons thought about it and agreed. Shang Liuyu's cultivation might be considered decent in this world, but in their eyes, it was not enough. She was even less capable than one of their elite leaders and could not cause any trouble. So they gave up the idea of ​​killing her now.

The Flame Demon Sea Siren even joked with Zuan: "You really are chivalrous, you haven't fallen for those sisters, have you?"

Zuan replied calmly, "They are all mine. It would be a waste to kill them."

The demons wore knowing smiles. Such a beautiful mermaid queen, killing and eating her would indeed be a waste.

The two sisters are a pair; the Lord of All Changes is a master of manipulation.

Zu An ignored the lewd looks from these people and led Shang Liuyu straight inside.

Inside was another separate secret room, which was soon blocked by a door with an endless sea carved on it, as if the surging seawater was alive and could rush out at any moment.

“It’s your turn.” Kachir looked at Zaun.

Sensing the surging ocean power emanating from the door, Zaun had an idea and immediately took the Crown of the Sea God to the door.

There's a ring on the door; the Crown of the Sea God can fit right into it.

After the Crown of the Sea God was placed inside, the entire structure suddenly lit up, and then the lines on the door seemed to come alive and began to flow.

The reliefs on the stone gate transformed into real seawater at a speed visible to the naked eye, until finally even the stone gate itself disappeared, becoming completely part of the ocean.

Seeing all this, everyone marveled. They wondered who had built it back then, as it seemed to contain an incredibly profound method of elemental transformation that even they couldn't fathom.

We are now in the deep sea, and this seawater contains endless destructive power. Once this seawater is released, probably very few of the people here will be able to save their lives.

Shang Liuyu thought to himself, "No wonder they were so eager to get me and the Crown of the Sea God; they wanted to open this mysterious passage."

She was, after all, a member of the mermaid royal family, and because of her sister, she was very familiar with the Dragon King. However, for thousands of years, neither the mermaid clan nor the Dragon King seemed to have any record of this passage, and they didn't know where it led.

The Crown of the Sea God flew back to the top of Zaun's head. Zaun seemed to understand something, and took Shang Liuyu's hand and walked straight forward.

As he approached, the gate formed by the seawater automatically parted to reveal a deep tunnel.

Seeing this, the others hurriedly followed. Once inside, they discovered that the walls on both sides were no longer made of stone or earth, but were formed by the sea parting to both sides.

Everyone subconsciously looked up and saw that it was also seawater above them. They were now more than ten thousand feet above the sea level. If this seawater were to suddenly crash down out of control, even a mortal immortal would probably be crushed into a meat patty.

The group looked at the magnificent tunnel with awe, their steps quickening as they wanted to leave the place as soon as possible.

After walking for an unknown distance, the group finally left the underwater tunnel and stepped back onto solid ground, and everyone breathed a sigh of relief.

However, not long after, the group was blocked by another wall. Unlike the previous one, this wall was not carved with anything related to the ocean, but with a huge ghost face.

The ghostly face was extremely ferocious, with two red flames burning in its eyes, staring straight at these uninvited guests, and the entire wall was filled with a thick aura of death.

Zuan felt a chill run down his spine. He noticed that not only the wall, but also a special magic circle on the ground, where all the runes gathered to form the image of a ghost face. The ghost face opened its blood-red maw, and the sharp teeth inside seemed to be emitting a chilling light.

Upon seeing this, Shang Liuyu couldn't help but feel a little scared and subconsciously leaned closer to Zu An's arms.
