In the End of the System, Was the Little Loli Selected by the System?

(The first three chapters lay the background, and after three chapters it starts to get exciting!) Hum, yes, I am the magician Shen Yu who lives in every dark corner of the world! Kill the system, the villain. It doesn't matter if you are lucky or have cheats, as long as you come into my sight, I will take away everything from you. By the way, I have no intention of falling in love, getting married, or having children for the time being, let alone starting a harem. Don't listen to the nonsense of that woman named Qin! Um? You ask me when did this kind of life begin? It all started when I was blocked in the men's room by a perverted system. . .
