Devil Fruit: Invincible from the Tremor-Tremor Fruit

When the fishmen army was at a disadvantage, the fishmen wizard appeared.

He had a strange figure, half human and half fish, his skin was a sickly blue-green color, and his eyes flashed with a cold light. He held a magic wand engraved with complex runes in his hand, and the head of the wand was inlaid with a gem that emitted a faint light, which obviously contained powerful magic power.

With the appearance of the fishmen wizard, the Blue City defenders immediately went on alert. However, they obviously did not expect that the fishmen wizard had such powerful magic power. He raised the magic wand high, muttered something, and the air around him began to vibrate violently, as if an invisible force was gathering rapidly.

Suddenly, a dazzling magic beam gushed out from the magic wand and rushed into the sky. Then, countless tiny magic rays swept towards the Blue City defenders like a net. These rays were extremely fast, making it impossible for people to dodge, and each ray of light contained a powerful destructive power. Once hit, the consequences would be disastrous.

Although the Blue City defenders were brave and good at fighting, they couldn't help but feel a little helpless when facing this unprecedented magic attack. They could only wave their weapons with all their strength to try to resist the attack of these magic rays. However, the magic power of the Fishman Mage was too strong, and the defense line of the Blue City defenders was soon torn into pieces.

At this moment, the entire Blue City was shrouded in panic and despair. People could only watch those magic rays raging in the city, but they could not make any effective resistance. The twisted Fishman Mage stood outside the city with a hideous smile on his face, as if he had foreseen the impending destruction of the Blue City.

When the Blue City fell into chaos and panic, a red figure quietly appeared on the edge of the battlefield. She was the "Rose Assassin", a mysterious killer of the Blue City forces, known for her elegance and lethality. She was wearing a tight red dress, like a blooming rose, and she looked particularly dazzling on the gray battlefield.

The Rose Assassin held an exquisite dagger in her hand, the blade flashing with cold light, revealing a dangerous and charming aura. Her movements were light and agile, as if she was dancing an elegant dance, and every step was precise and powerful.

In the chaotic battle, she quietly approached the Murloc Archmage who was casting a spell. The Archmage was immersed in his magic attack and was completely unaware of the approaching danger. The Rose Assassin aimed at the opportunity and shot instantly. The dagger drew an elegant arc in the air and accurately pierced the back of the Murloc Archmage.

Everything happened too quickly, and when the Murloc Archmage reacted, it was too late. He widened his eyes, looked at the dagger on his chest in disbelief, and then slowly fell down. The Rose Assassin gracefully pulled out the dagger, gently wiped off the blood on it, and then turned and disappeared in the chaotic battlefield, leaving only a red afterimage.

As the Murloc Archmage fell, his magic attack also dissipated, and the Blue City defenders got a chance to breathe. They all looked at the disappearing red figure, their eyes full of gratitude and awe.

When Rose Assassin was about to leave after completing the assassination mission, she saw a woman so beautiful that she was moved walking out of the army of fishmen.

"Rose Assassin, you are indeed an amazing killer." Boa Hancock's voice was low and provocative, "But in front of me, maybe you should stop dancing."

Rose Assassin stopped and slowly turned around to face the sudden challenger. Her eyes were cold and deep, as if she could see through the truth behind all appearances. She didn't speak, but just held the dagger in her hand tightly and stood quietly in a defensive posture.

Boa Hancock saw this and a wild smile appeared on the corner of her mouth. She didn't have any weapons, but her hands were her most powerful weapons. She flashed and rushed towards Rose Assassin at lightning speed, her hands turned into afterimages, attacking the opponent's vital points.

A hint of coldness flashed in the Rose Assassin's eyes. She did not flinch or dodge. At the moment when Boa Hancock was about to touch her, she swung the dagger in her hand fiercely and stabbed Boa Hancock's chest at an almost impossible angle. This move was both ruthless and accurate, and it was obvious that she wanted to kill the opponent in one move.

However, Boa Hancock was not an ordinary person. She dodged this fatal blow sideways at the critical moment, and at the same time, she grabbed the Rose Assassin's wrist with her backhand, trying to take the dagger from her hand. The two moved as fast as lightning, and in a blink of an eye, they had fought for several rounds.
