The Miasma: Idle Survival

The Last Source of Breath, Humanity's Survival Rests in Your Hands

Deadly toxic miasma has shattered civilization, reducing the world to a festering wasteland. The legendary "Miracle Tree," said to purify the atmosphere, is now humanity’s final hope. As its guardian, you must nurture the ancient tree, expand pockets of pure land, and fight off twisted mutants and raiders to reclaim humanity’s right to breathe.

Core Survival & Building​

► ​Cultivate the Tree of Purification​

Draw power from the earth, consume purification crystals to fuel the tree’s growth.

► ​Dynamic Pure Land Ecosystem​

Plan automated irrigation systems, build oxygen-dome farms, deploy light barriers—but energy overload may trigger vegetation枯萎 riots.

► ​Stealth Missions in the Toxic Zone​

Venture deep into poisoned lands wearing respirators:

Harvest glands from mutated carnivorous plants for antidotes

Lure away phosphorescent armored drakes with sonic decoys

Retreat swiftly to safety before acid rain corrodes your gear

► ​Decipher Ruined Civilization​

Crack codes in ancient climate stations, restart purification tower cores, and uncover the truth behind the "Genetic Cataclysm" that doomed the world.

Survivor Decision Network​

Taking in refugees boosts productivity, but food shortages may spark riots. Sending expeditions to plunder other camps could trigger "Blood Oath Revenge" events.

​Apocalyptic Rules​

The tree must consume 10 pollution cores daily to maintain purification, or the pure land will shrink.

During the monthly "Tide of Corruption," corrosive rain disables all metal weapons.

Your blood is the tree’s finest nutrient—but each sacrifice permanently reduces your health limit.

Final Warning​

When every breath is a luxury… will you become the nourishment that allows the tree of civilization to pierce the abyss?

​Take root here and plant humanity’s last future!​​
