Sign-In System in the Myriad Worlds

After transmigrating, he binds himself to a System. Sign-in Systems are all the rage these days, but this one seems rather unorthodox. It constantly teases its Host, and its intelligence is so high that it practically toys with him. Yet this abnormal System is incredibly powerful, at least ten thousand times stronger than those other Sign-in Systems that only look impressive!
