After Total Destruction, the Girl in the Sword Wants Me to Conquer the World

When Clyde opened his eyes at the edge of the broken leaf forest, there was nothing in his mind. The name was told to him by this body. Origin? Don't remember. An adventurer named Gareth picked him up. Three days later, four people entered the cave to execute the subjugation order, and an unexpected monster appeared, nine meters long and with dark red eyes. Gareth is dead, Ella is dead, Lena is dead. Clyde should have died together. He pulled out a sword with a white scabbard from under the stone tablet. White light emerged, and a girl with white hair and bare feet stood in front of him. She didn't ask his name or explain who she was. She stretched out her hand and said something. "Come with me to conquer this world, and take all suffering, cruelty, and death under your control. Let this world return to its original state." Clyde took her hand. He had no idea anyone had done the same thing thirty years ago. I wonder if the Black Tower will rise from the ground again. I don't know that the dragon will fly from the end of the sky. This familiar scene gave him hope again. "Come on, let the world see how awesome we are."
