Every World Is a Dungeon Instance, and I Am the Merchant of All Realms

Wang Duoyu finds a kaleidoscope connected to all worlds. It randomly links to a dungeon from the myriad heavens.

Every world is a dungeon. He can only enter the next one after clearing the current dungeon.

Second chamber: Romance of the Three Kingdoms X. The Hermit of Six-One. See how Wang Duoyu breaks out of the predicament.

Third chamber: The Story of Huo Yuanjia. Wang Duoyu helps Huo Yuanjia establish the Chin Woo Athletic Association, saves him, smashes the sign branding China the Sick Man of East Asia, and fights back against foreign invaders.

Fourth chamber: Diablo II: Lord of Destruction. He helps humanity resist the demon armies and slays the Seven Lords of Hell.

Fifth chamber: The King's Avatar. He returns to the top alongside the protagonist, Ye Xiu.

Readers decide which dungeon comes next by voting. The one with the most votes wins. In a tie, the first nominated option takes it, and votes for the losing options carry over to the next round. When there are no dungeons in the pool, the author is free to make things up.
