Seven Days of Endless

This is a maze with no exit, made up of the remains of countless annihilated civilizations. This is a journey with no past, only a seven-day countdown to death. Welcome to the Hall of Echoes. The amnesiacs left here must search for a relic called "Echo" among the bizarre ruins, piece together the fragments of the truth from the broken images, and gain weak power. They must be constantly vigilant about: In the wrong corner, "withering" can turn people into ashes; In the midst of excessive noise, Sound Patrol brings complete silence. Silent words, Liuying, Panshi, Baixiao... Strangers with code names, are each other's only support, and may also be a sharp knife stabbing in the darkness. In this desperate reincarnation, they are not only looking for a way out, but also for themselves and their way back to be swallowed up by this strange palace. When the last echo dissipates, will the world end, or will the truth be revealed?
