The third layer of space unexpectedly empty, just like a prepared battlefield. Black Blade and Bexia stood below the stairs, Black Blade stopped and looked ahead into the darkness.

"Puh! Puh! Puh!..."

Blue flames rose from both sides of the ship's walls. The dim blue oil lamps gave off a chilling feeling, as if the burning was not flames but ice!

"Invader, if you don't want to die, leave now!" a voice came from the darkness. It sounded strange and eerie. The owner of the voice gradually appeared in front of everyone on the stairs leading to the next level.

"Hiss!" Bexia took a sharp inhale as she looked at the "monster" in front of her.

The owner of the voice was too terrifying. His entire body was a sea blue color, with a fish tail instead of human legs. Scales covered his body, and his whole body floated half a meter above the ground.

What truly frightened people was his wild hair, or rather, it had surpassed the human understanding of hair. Mold's hair was not hair at all; it was a group of small snakes, still alive, wriggling crazily on top of his head, their eyes glowing red.

"Are you the Sea Nymph Mold?" Black Blade frowned as he looked at the Sea Nymph in front of him. The pressure from Mold was not small, and his strength surpassed Black Blade's by quite a bit. The outcome of a battle was uncertain. However, Black Blade had no intention of fighting to the death right now. Simply restraining him would not be a big problem.

"I advise you not to believe Ru Jie's words. It might not be a good thing if you lose your life later!" Mold said calmly.

"Unless I try, how would I know?" Black Blade's intentions were clear, so he didn't plan to waste time with Mold. Whether Ru Jie had any problems was irrelevant. Would a king fear someone who had been dead for so many years?

Black Blade took his long sword down from his shoulder, and magical power surged all over his body. A thin layer of magical protection appeared on his body, but there wasn't a significant fluctuation in magical power.

Kings were already beyond ordinary people. Their control over magic was not as rough as regular people. They had strong control and reached the pinnacle of using magic. Therefore, during battles, unless there was a strong collision, it was rare to see the brutal scenes of Extreme violence.

The more powerful a king, the better their control over strength, and the less magic leaked out. This allowed them to sustain a battle for longer and fully utilize the same amount of magical power.

"Hmph! Greedy humans." Mold naturally understood that Black Blade was after his treasure, so his expression naturally couldn't be good.

Mold took out his weapon, a deep blue steel fork. The Sea Nymph clan used three-pronged forks for battle. Only the Sea Nymph Emperor would use their clan's inherited Artifact, the "Starfish Trident"!

Mold didn't waste any words. With a flick of his fish tail behind him, it was as if he was moving in water. A ripple appeared in the air, and Mold instantly appeared in front of Black Blade. The three-pronged fork thrust towards Black Blade's chest.

"Clang!"

Black Blade blocked the attack with the large blade, but he still took a small step back. However, he didn't fall behind. A bright light flashed in his eyes.

"The Eye of the Eagle!"

"Black Blade Reversal!"

Black Blade's long sword spun, skillfully tipping the three-pronged fork away from Mold. At the same time, the long sword fiercely struck Mold's tail.

"Ding!"

However, it wasn't easy for Mold to be struck. He immediately blocked Black Blade's attack with his three-pronged fork, but this collision sent him back more than ten meters. Of course, this was intentional on his part to create distance.

"Ice Arrow Barrage!"

After retreating, Mold immediately waved his three-pronged fork. Water magic crazily condensed into dozens of ice arrows from all angles and flew towards Black Blade.

"Earth Splitting Slash!"

Fearlessly, Black Blade raised his long sword, and a black, huge, blade aura spread out from the ground. All the ice arrows in front were crushed. At the same time, this blade aura continued towards Mold with undiminished force. However, it didn't have much power left and was shattered by Mold's fork.

The two fought for a while, but Black Blade had the upper hand. This was not because Black Blade was stronger than Mord, but because Mord had very little life left. His body was not in its normal state. If he were to unleash all his power, it would be a huge damage to him and would cause his already limited life to come to an end faster.

"It's your turn, kid!" Black Blade's voice came through clearly. Although he didn't turn around, it was easy for someone with the power of a king to communicate through telepathy.

Bexia didn't reply. He glanced at Mord in the distance. After a few exchanges, they were now in a standoff with Black Blade. Their auras clashed with each other, invisible but strong enough to gravely injure anyone standing between them.

The entrance mentioned by Luge wasn't the staircase leading to the next floor. It was actually behind Mord. With his "Shadow Body Cloak," which was almost at the quasi-king level, it was unlikely that he could hide from Mord's perception at this close distance.

The real entrance that Luge mentioned was in another corner. It was originally a damaged part of a ship but later turned into another ventilation duct. That was where Mord set up a weak point in his barrier.

Bexia followed the route Luge described and found the ventilation shaft, which wasn't too far from where he was. The barrier here was indeed weak, and Bexia easily passed through the barrier's power, leaping into the darkness and gently landing on the ground after a moment.

"Here..." Bexia looked at the space in front of him. The entire fourth floor was illuminated by a large piece of sea blue crystal, or rather, a large crystal box filled with glowing blue liquid. He could feel the abundant magic power gathering around the crystal box, almost as if it couldn't be dispersed.

In addition, the fourth floor also contained many shelves filled with various things - magic books, magical equipment, materials, and various props. Each item emitted powerful magic. If the strength of magic was the only factor considered, more than half of the things here were stronger than the "Magic Concentration Ring" in his hand. Each of them would be considered a priceless treasure in the outside world.

However, what Bexia cared most about was the Elixir of Eternal Life. These treasures were mere external items, but the Elixir of Eternal Life and other life-enhancing substances were truly priceless and couldn't be measured by money. That was the real invaluable treasure.
