Gu technique, killing invisibly, is one of the most mysterious means in the world.
Chen Nan stood in the shadows outside the sports arena, his eyes indifferent as he watched Inobe Kogoro and the others leaving in the distance, a cold smile appearing at the corner of his mouth.
He moved his heart, and the King of Ten Thousand Gu inside his body quietly awakened, transforming into an invisible breath, silently penetrating into the bodies of those members of the Japan delegation.
The King of Ten Thousand Gu is the king of all Gu, controlling thousands of poisons invisibly, even the top martial arts masters have difficulty detecting its presence.
Chen Nan did not let the King of Ten Thousand Gu take Inobe Kogoro and the others' lives directly, but ordered it to plant a special poison in their bodies.
This poison is colorless and odorless, lurking within the human body, only to activate twenty-four hours later.
