What System Do You Want

Traveling to the world of immortality, there is no golden finger, so you can only engage in literature? No, the game has just begun since I learned to build the system. Fight monsters and upgrade the system, unlock a thousand times experience, and get 999 with one sword! Charm value system, become a male god from another world! Check-in system to collect famous rare treasures that are over a billion years old. Treasure hunting system, synthesis system, European God system, summoning system, lottery system, copy system, cheat system, home system, sect system, emperor system... Just ask who else! Don't ask why my little brothers are so awesome, because I sent them the system.
