Engineer Shi Lin transmigrates to the interstellar era and becomes a sickly, good-for-nothing Omega. His once mighty snow leopard spirit form has regressed into a frail white cat, missing limbs and liable to vanish into thin air at any moment.
"How can a kitty be made to suffer like this?"
Abandoned by his family, Shi Lin takes matters into his own hands and equips his spirit-form kitty with awesome mechanical prosthetics.
The mechanical kitty grows more and more lively, and Shi Lin settles into a life of being disliked by everyone, but having a cat to pet.
Just then, his eldest sister Shi Ruoxiao, whose spirit form has awakened as a phoenix, slaps a marriage contract down in front of him.
"Two good-for-nothings are a perfect match. You can take this marriage."
It turns out the Shi family and the Marshal's household had long been bound by a marriage agreement. The intended groom is Fu Jinsheng, once a heaven-blessed prodigy and now a fallen young master.
Fu Jinsheng has yet to differentiate, let alone awaken a spirit form. In an era where a person's strength is judged by their spirit form, he is indeed no different from a cripple.
Shi Lin is eager to get away from this family. He quickly packs his belongings and races toward a life with freedom and a cat to pet.
On their wedding night, Shi Lin tells Fu Jinsheng, "I'm in poor health, and you can't differentiate. That's fine. From now on, the two of us and one cat can make a life together."
Fu Jinsheng's gaze is dark as he looks at the mechanical kitty, whose entire body is mechanical except for its fluffy tail. He nods. "All right."
*
Fu Jinsheng has a special constitution. Before he differentiates, his spirit form awakens: Void, a divine beast capable of devouring all spirit forms and laying waste to the world.
He doesn't want to hurt anyone, so he refuses to differentiate. As a result, the whole world abandons him.
Dark emotions grow within Fu Jinsheng. Before he can completely lose control, he meets someone, along with that person's mechanical cat spirit form, which isn't afraid of Void.
The man smiles brightly.
"I'm really good at this. I can repair mechs and support you."
"It's all right if you can't differentiate. You can borrow my kitty to pet~"
Fu Jinsheng rubs his forehead. "Do you know what it means to let someone else pet your spirit form?"
