Myriad Worlds: I Wield the Human Emperor Banner, Yet They Call Me the Demon Lord

[Myriad Worlds] + [Decisive and Ruthless] + [Invincible] + [Fast-Paced] + [System] + [Doing as One Pleases] + [N Tool People] (Based on reader feedback, the big shots don't seem to like leisurely farming and everyday-life stories, so the direction changes starting in Volume Three, Chapter 104.) An old man claiming to be a god sends him to another world and grants him three wishes. Eternal life, the Myriad Worlds, and the strongest System. From the start, he arrives in the otherworldly fantasy of A Certain Scientific Railgun and obtains the Emperor's Banner. Meng Shuai: "System, why is this Emperor's Banner still giving off black smoke?" System: "It's just so dense that it looks black." "Why does everyone call me the Demon Venerable?" "They just don't know how great you are, Host." "System, did I really do something wrong?" "The Host is never wrong. You only ever do the right thing." A figure appears at the end of the river of time. Tens of thousands of mighty beings from the Myriad Worlds surround the Silent Heaven Demon Venerable, their killing intent blazing. Even a wisp of the aura they release can easily destroy a small world. Meng Shuai turns and sits down. A throne of white bones appears, and behind him rises the Emperor's Banner, its shadow blotting out the sky. Terrifying demon kings stand in rows at either side. The mighty beings of the Myriad Worlds swallow nervously, resisting the pressure of the great demons. Resting his head on one hand, Meng Shuai says listlessly: "Why have you brought killing intent with you to meet me?"
