Then, when the myriad races of the previous era revive, they discover a terrifying human on Blue Star who eats everything in sight… (The early chapters focus on city life, then gradually shift to spiritual qi revival. It takes time, so don't read if that bothers you.) (Give it 30 chapters. If it's no good, come and take my head!!!)
