I opened the treasure chest in the ghost blade

Haneda Ryuichi, who had transmigrated to the World of Ghost Destroyer, had obtained the Treasure Chest System. He could draw all kinds of super items and powerful skills, such as the top-notch breathing technique, the sword of the Grim Reaper, the domineering aura of One Piece, and the Demon Eye of Death of the Moon-shaped World!

He was the most powerful trainer in the world, and he was also the most powerful Ghostblade killer in the world.

"Haneda Ryuichi, can you not kill me?"”
