Zhang Kui has already confirmed that the power of the "You Dynasty" is linked to the extraterrestrial enemies.

Through specially made altars, they performed blood sacrifices to unknown entities across distant time and space, a main feature of these "alien invaders," starkly merciless and brutally cold-blooded.
