文明融合

From a stone to a civilization

You start with a stone and a handful of water. There is no tech tree that hands you progress — every new element must be merged by hand .

Fire + Stone = Flint → Flint + Stick = Torch → Torch + Wood = Campfire → Campfire + Mud = Pottery…

223 elements and 230 recipes, drawn from the real arc of technological history. What you craft is not a game item — it is a road humanity actually walked.

Ten dynasties, ten cities

Stone, Xia, Shang, Zhou, Qin, Han, Tang, Song, Ming, Qing. Every era shift:

Rebuilds the city skyline — thatched huts give way to flying eaves and bracket sets

Changes which building types exist, and moves them where that era would place them

Rearranges the elements and recipes available to merge

Twenty buildings upgrade individually, and levels follow the building, not the era — the forge you raised in Tang is still there in Song, and still upgradable.

More than numbers

Chronicle — 62 historical entries unlocked by progress, each with readable prose.

Codex — every recipe pops a discovery card on first craft. Recipes you have not made show as ??? — no spoilers.

Knowledge tree — 60 topics, each one citing its historical source.

Achievements — 52 of them, from "first merge" and "complete one dynasty's codex" to "clear all 74 levels" and "visit every dynasty".
