Weak Pup? I'll Upgrade Forever

Yuehao wakes up in the body of a small white wolf. He is the discarded offspring of the previous empress, who was overthrown, which puts him at the bottom of his bloodline and makes him a target. Assassins close in almost immediately. Before that he was an ordinary man who barely left his room at home, and he does not know how he got here. A system that strengthens him binds to him while he is cornered. He grows from a weak wolf by pushing past his limits and beating stronger opponents, working toward taking back the throne his ancestors held, though the loss of that empire has more behind it than he knows.
