Once I Traveled Through Time and Had a Son

(Trap) I, once traveled through time, became the successor of the successor. I have lived alone for 18 years, and now I have to raise another child. I am just an ordinary person, but my son is not, but I don't need him to become an immortal. After all, my son is not an ordinary person. He fell off a cliff and met his grandfather. For me, just lying flat is enough!
