Peerless Imperial Physician

(Not a son-in-law + not suppressing the realm + traditional urban immortality + decisive killing + not suppressing the protagonist + the school belle CEO's backlash + invincible push!) Five years ago, he was framed as a murderer because he accidentally witnessed a murder and arson. He was taken away on his fifteenth birthday and sentenced to death. Five years later, the man who should have been shot long ago returned against fate. Since no one will redress my injustice, I will kill all those who harmed me. I am the emperor's doctor, I am the one who can bring people back to life, and I am the only one who can use immortal magic to reach the gods.
