Sister, You Are Actually the Leader of a Cult?

Code writer Wang Mingxuan encountered a fantasy world and had only one sister in his family. My sister not only has the beauty of a country and a city, but also has the appearance of a fish sinking before a bird falls, and the beauty of a woman shy of the moon. My sister is also very rich and controls 80% of the wealth of the Qin Empire. After awakening to the system at the age of eighteen, Wang Mingxuan began to check in at various places without telling his sister. Because the system allowed him to hide for ten years. He is not allowed to reveal his strength within ten years. When I'm busy, I check in and act chivalrously. When I'm free, I go to my sister to show off. Living like this, what's the harm if you don't become an immortal or a god? Until one day. Wang Mingxuan looked at his sister who was surrounded by a mountain of corpses and a sea of ​​blood, as if she were taking a leisurely stroll in a garden, with a look of shock and disbelief on his face. "Sister, you are actually the leader of a cult?" "Brother, are you actually the sword immortal?" Since then, there has been a very ferocious brother-sister combination in the world.
