· Added a medium difficulty map [City of Ashes], the map area will gradually open as the lava cools; At the same time, a new boss called "Ghost Lord" has been added, which will summon harvesters to raid your position.

· Balance adjustment: The monster "Sunflower" can only heal other enemies and will no longer heal itself; Monster [Ghost Mage] summons ghosts at a lower frequency, while reducing health and increasing speed.

· Added automatic save function, allowing players to read files and continue playing after abnormal or forced exits.
