Xueba Starts from Daily Sign-In

Su Chen accidentally obtained the daily sign-in system. Math scum? It's okay, just sign in. "Ding, you signed in successfully and gained proficiency in mathematics!" Trigonometric functions, linear algebra, all SOEASY! Learn in seconds. Is it awesome to speak four languages? I'm afraid you have never seen the world. "Ding, you signed in successfully and gained proficiency in all languages!" The heads of state were shocked, "That's awesome, he actually understands alien languages!" From then on, Su Chen went further and further on the road to academic supremacy, becoming omniscient and omnipotent.
