So I remember reading a mtl of a book that was basically a straight rip off of Swallowed Star. At the start it was much more like regular xuanhuan rather than postapocalyptic scifi. The mc had a disabled brother, he joined a squad and one of their squadmates got disabled (shot in the eye instead of losing an arm) he stole a dragon egg, found a ship that had a deceased master and the ship had a tool spirit which was just like Babata or whatever that AI's name was. There was a dog which was devouring things just like the swallowing beast and he was manipulating a shuttle with his soul power. He was also a spear user if that helps. That's all I read up to but I can't remember the books name.
