I Killed The Immortal

I Killed The Immortal
My name is Arthur Gottfried and I just wanted to marry the mayor’s daughter. Now my lower body lies two meters away from me. But I couldn’t even die. The Immortal has snatched me from the hands of death and made me his student.   “Kill me”, he said. “And you’ll return home”.   Why did he want me to kill him? He never told me that.
