Development covered 16 Jun 2026 to 20 Jun 2026 (commit dates).
I'm building Myriad Immortal Sect, a xianxia idle RPG, and the question that shaped the first hundred commits was not "what should the player click". It was "what is the game allowed to give the player for free". Idle games drift toward mush: every system eventually produces everything, numbers inflate, and the world map becomes wallpaper. The genre I'm working in hands you the fix for free.
Two economies, one wall
In xianxia fiction, cultivation is internal. Pills, manuals, flying swords and spirit herbs are external. A cultivator who never leaves the cave is safe, and stuck. That division became the game's hardest design rule: every reward is split by source. Meditation, breakthroughs, quests and skill nodes grow the internal side, things like qi and insight. External goods come only from the world: hunting beasts, gathering herbs, trading in a frontier town, a sect's contribution store. Neither faucet feeds the other. An idle stretch settles cultivation and never mints a pill. A treasure you buy never grants raw cultivation. Closing the second path is what keeps the first one honest.
Making the wall visible
A rule the player cannot see might as well not exist. So every breakthrough attempt lists its requirements with the source attached: this much qi from meditation, those pills from the world. When an attempt is blocked, the label says which side came up short, and the always-present guidance card points at alchemy when the missing piece is external, instead of telling you to keep meditating at a wall. Most of the UX work in this stretch was that translation, turning an internal invariant into sentences a player can plan around.
Lifespan is the budget
Pure idle games answer "when" with "now, plus a multiplier". Xianxia offers a better clock. Your cultivator has an age, cultivation slows past a certain point, and reincarnation resets the run while carrying talents forward. Lifespan turns the pacing question from "how much" into "how long", and it quietly makes the map matter: the goods that stretch what your remaining years can buy are all outside the cave. Mortality is the retention mechanic. It also gave the balancing pass a lever the genre understands: the ladder runs across ten great realms with tribulations between them, and each realm's pace is a deliberate curve choice, tuned against how many of your years a full climb should cost.
A ceiling the whole world shares
The asynchronous multiplayer layer breaks when veterans lap newcomers. Breakaway wins kill shared worlds quietly, long after the screenshots looked fine. The mortal world therefore runs on a realm ceiling shared by everyone, rising as the world ages. Your breakthroughs wait at the same wall as everybody else's until the world moves. It reads to players as the world having its own weather, and it keeps early adopters and day-300 players inside one race.
What this buys
With the wall in place, everything built on top lands softer. Sects become faction identities with their own admission and rank ladders rather than buff vendors. Quests can pay in external goods without inflating the idle loop. The next hundred commits are about the shared world itself, and the wall is the reason I expect that to stay balanced without a hundred emergency patches.
Play it
Myriad Immortal Sect is a free browser-based Idle Cultivation Game that needs no install and no account to start. The full devlog series lives there as well.
