Chapter 466: Eliminate the Men in Black

Usopp and Chopper nervously walked towards the depths of the cave, taking every step very cautiously, as if they were in a minefield full of traps. Usopp held the slingshot tightly, beads of sweat rolling down his forehead, his eyes fixed on the darkness ahead, and whispered to Chopper, "Chopper, we have to be careful, we don't know what kind of monster is in there."

Chopper was holding a small first aid box in his hand, which he prepared for emergency treatment. His body was trembling slightly, but he still nodded calmly: "Okay, Usopp, let's go together." His little hooves left a slight sound on the ground of the cave, which was particularly clear in this silent environment.

As they went deeper, the roars became louder and louder, and the cave was filled with a pungent smell. Suddenly, a huge claw stretched out from the darkness, and the claw was covered with sharp barbs, which flashed coldly in the weak light. The claw slammed the ground hard, raising a cloud of dust, and the cave shook.

Usopp yelled, "Watch out!" He quickly drew his bow and fired a "fire star" in the direction of the claw. The bullet exploded the moment it touched the claw, igniting a ball of fire that illuminated a small area around it. With the light of the fire, they saw the full appearance of the monster - a black panther as big as a mountain, its eyes were like two green lanterns, emitting a fierce light, its black fur was shiny and smooth, and its muscles undulated under the fur, showing its powerful strength.

The black panther was enraged by the flames. It opened its bloody mouth, showing its sharp fangs, and let out a deafening roar, rushing towards Usopp and Chopper. Chopper hurriedly threw the medicine box to Usopp, then ate a blue ball and "strengthened his wrist" again. "I'll stop it!" Chopper shouted, rushing towards the black panther, using its huge body and powerful hooves to collide head-on with the black panther. The two collided with a loud noise, and Chopper was shocked and took a few steps back, but he still stood firm.

"Chopper, hold on!" Usopp shouted as he loaded a "Exploding Star" onto his slingshot. He aimed at the Black Panther's eyes and fired it with force. The ammunition flew accurately towards the Black Panther's right eye. The Black Panther sensed the danger and wanted to dodge, but it was too late. The ammunition exploded near its right eye. The Black Panther roared in pain, and its right eye was injured and bleeding.

The black panther became even more violent, waving its claws and attacking Chopper madly. Chopper tried to dodge, but was still cut several times, and the blood dyed its fur red. "It hurts!" Chopper yelled, but he didn't mean to back off.

Usopp was very worried when he saw Chopper was injured. He looked around the cave for something useful and suddenly found some loose stones on the wall of the cave. He had an idea and ran over to pry the stones hard, shouting, "Chopper, lead it over here!"

Chopper heard Usopp's words and moved towards Usopp while dodging the black panther's attack. The black panther chased after him, and when it caught up with Usopp, Usopp used all his strength to pry a huge rock. The rock rolled down towards the black panther. Although the black panther sensed the danger, it was too fast to avoid it completely. It was hit on the hind legs by the rock and roared in pain again.

"Now, Chopper!" Usopp shouted. Chopper gathered all his strength and rushed towards the injured hind leg of the black panther, and hit it hard with his horn. The black panther's hind leg was broken by Chopper, and it completely lost its balance and fell to the ground.

Usopp and Chopper thought the crisis was over and just breathed a sigh of relief, but they found that the black panther had not given up struggling. It supported its body with its front paws and roared at them again, with an even more fierce look in its eyes.

"This guy is really tenacious!" Usopp gritted his teeth and took out all the remaining ammunition from his backpack, ready for the final battle with Black Panther. Chopper also prepared for the battle again, his eyes were firm: "We must defeat it!"

The black panther pounced again, and Usopp fired all his ammunition at once: "Sure kill, multiple star bombs!" Countless ammunition flew towards the black panther and exploded on the black panther, creating a huge impact. The black panther was pushed against the wall of the cave by the power of the explosion and hit it hard. This time, it finally had no strength to stand up, fell to the ground, and slowly closed its eyes.

Usopp and Chopper both collapsed to the ground, both of them with varying degrees of injuries. Usopp panted and said, "Chopper, how are you?" Chopper replied weakly, "I'm fine, just a little tired and a little painful."

They rested for a while, and Usopp took out medicine from the medicine box and simply treated each other's wounds. "We have to leave here quickly and go back to find Luffy and the others." Usopp said.

Just as they were about to get up and leave, a strange sound came from deep in the cave, like someone was chanting in a low voice, or some kind of ancient spell. Usopp and Chopper looked at each other, their eyes full of fear.

"Will there be any new monsters?" Chopper said tremblingly.

Usopp gripped the slingshot tightly, "Whatever it is, we have to go check it out. We can't let it threaten everyone."

They walked cautiously towards the source of the sound. The closer they got, the clearer the sound became. When they turned a corner, they saw an amazing sight - a huge round stone platform appeared in front of them. The stone platform was engraved with various mysterious runes, and the runes were shining with strange light. In the center of the stone platform, a man in a black robe was chanting a spell, and some crystals emitting black aura were placed around him.

The man in black robe seemed to have noticed their arrival. He slowly turned his head, and through the gap in his black robe, a pair of eyes flashing red could be seen. "You ants, you actually came here and you are really courting death." The man in black robe had a low and hoarse voice, full of malice.

Usopp summoned up the courage to shout, "Who are you? What are you doing here?"

The man in black robe laughed eerily: "I am the messenger of darkness. I am here to awaken the dormant power, and you will be the sacrifice." After saying that, he raised his hands, and the crystals around the stone platform glowed brightly, and a powerful dark force began to spread in the cave.

Usopp and Chopper felt the horror of this power, and they knew they had to stop the black-robed man. Usopp fired a "paralysis star" at the black-robed man, and Chopper rushed towards the stone platform, trying to destroy the crystals.

The man in black robes easily avoided Usopp's attack. He waved his black robes and a dark energy swept towards Chopper. Chopper was hit by the energy and flew out, falling heavily to the ground.

"Chopper!" Usopp yelled. He rushed towards the man in black robes regardless of everything, shouting as he ran: "I won't let you hurt Chopper!"

The man in black robe sneered, "Stupid guy." He cast magic again, and many black tentacles appeared on the ground, wrapping around Usopp. Usopp tried his best to dodge, but his feet were still caught by the tentacles and he couldn't move.

Just as the black-robed man was about to launch a fatal attack on Usopp, Chopper struggled to get up from the ground. He ate the last blue ball and entered the "runaway enhancement" state. Chopper's body became bigger, his hair stood up, his eyes were full of bloodshot, and he roared at the black-robed man: "Don't hurt Usopp!"

Chopper's attack caught the black-robed man off guard, and he was knocked back a few steps by Chopper. Usopp took the opportunity to break free from the tentacles. He saw that Chopper had entered a dangerous rampage state, and he was moved and worried. "Chopper, let's defeat him together!" Usopp shouted.

They joined forces to attack the black-robed man. Usopp used his slingshot to constantly interfere with the black-robed man, while Chopper used his powerful force to fight the black-robed man in close combat. After a fierce battle, the black-robed man gradually revealed his flaws.

Usopp saw the right moment and fired a special "Demon Star" that he had made. This bullet contained powerful energy and hit the black-robed man directly. After being hit, the black-robed man spurted out a mouthful of blood, and his black robe began to break, and the dark power began to get out of control.

With the defeat of the black-robed man, the crystal light around the stone platform gradually dimmed, and the dark power in the cave slowly dissipated. Usopp and Chopper successfully prevented a crisis. They sat on the ground tiredly and smiled at each other.

"We did it, Usopp," Chopper said weakly.

"Yeah, we have to go back and tell everyone." Usopp said.
