In Demon Slayer, I’ve Just Become Upper Rank Three. Calling the Nation for Help

Tong: Reporting, sir. There's a Fist Pillar facing me.

Third Brother: Reporting, sir. There's an Ice Pillar facing me.

Muzan: You two, go spring camping.

[You report Muzan's coordinates, and the Dragon Nation launches its “space-based weapons” deployment!]

[You submit a sample of demon blood, and the Dragon Nation's biotechnology department develops a “gene blocker”!]

[You provide the layout of the Infinity Castle, and the Dragon Nation's engineering institute designs a “spatial jammer”!]

[You identify the target. Dongfeng Express delivers, guaranteed!]
