My Guardian Is an Ice-Cold Goddess of War

I was bound to a world-saving quiz System, and every livestream determined the fate of humanity.

The nation sent its strongest female warrior to protect me around the clock. She was as cold as ice and peerless in combat, yet she worried only about me.

When the whole world wanted to control me, she shielded me with her own body. When she was gravely wounded for my sake, I overturned the rules for her.

Only later did they understand: the cultivation techniques I released to the public would usher in a new era. And she was my only protector, as well as the reason I chose this world.
