I Became the System, Bound to the Villain Host at the Beginning

I accidentally learned that my sister was selected by the system to travel through all the worlds. At this time, the system administrator bound to Su Bai ran away and he inherited the system. From then on, Su Bai transformed into a system, traveled through the heavens and all realms, and embarked on the journey to find his sister. The villain must die? No! Bind the "Villain System" quickly, the Son of Destiny! Not good enough? Come! Bind the "Chop Knife System", no matter how skilled you are, you are still afraid of the kitchen knife! Many years later... "Ding, Su Bai's Ten Thousand Realms Travel System has been activated. Do you want to bind it?" Su Muxue's eyes widened: "Su Bai? Brother! How did you become a system!? Where is my original system?"
