It's a specialized Mind-controlling Starship created by the Mechanical Spirit Empire.
The Cursed Spirit Clan blood-cursed the Transcendents of the Mechanical God Sect, these technology-path followers who advocate the weakness of flesh and the ascent through machinery.
They crazily self-modify into half-mechanical beings, bioengineered humans, Mechanical Warriors, Mechanical Giant Beasts, and all sorts of super mechanical lifeforms.
Their base composition is also Cosmic Humans, but the ruling class consists of silicon-based life forms, purely Mechanical Life.
As for the Cursed Spirit Clan, they're like a group of Wizards who specialize in the Spiritual System witchcraft, originally just a native tribe of a planet that abandoned their original bodies to massively invade the Mechanical God Sect.
They completely seized a branch of Mechanical Giant Beasts and combined their innate spiritual talents to create these Mind-controlling Starships.
