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".
