Yuanka Boy

In the world, cards are king, and he is a BUG. Su Ye is an ordinary high school student. The greatest pleasure in life is to make up a secondary school setting in his head - codenamed King Jinyuan, with the Mu Tian Seal sealed in his body. He knew he made it all up. Until that rainy night, he unexpectedly crashed into the card battle space. Only the two combatants are allowed to enter the battle space. This is an iron law in the card world. The black card of forbidden power shattered in front of him, and the little girl he rescued put the unique gold card in the world into his hand. Relying on this gold card, Su Ye was admitted to the most mysterious card academy in the world. The secondary settings he had imagined came true one by one. Yuan Ka awakened in his body, and someone in the dark began to investigate him. And the Mu Tian Seal he casually made up is cracking bit by bit. His chuunibyou is actually the truth that the whole world is looking for. This is the story of a stupid kid who crashed into a world that didn't belong to him and then poked a hole in the sky.
