Most Ancient
超古代文明
Most Ancient is a Battle Cats stage in Spring Sprang Sprung. It costs 80 energy and sends 11 enemy spawn lines — led by The Face as the boss — against a 200,000 HP enemy base, and clearing it rewards 11,280 XP. Its enemies carry the Floating and Red traits, so cats that target them do the most work here.
