HP: I Have an Extra Father in the Magical World

(My sincere thanks to Professor Snape, no cp, the author is a novice, and is a bit of a fan. I created it because I really couldn't find one that suited my taste. Please forgive me if the writing is not good. Of course, the author is very persuasive, but if you really feel that the author's writing is not good, you can leave on your own if you can't stand it. There are thousands of good books, so don't hang yourself here.) Mu Cheng is a well-known genius in the world of cultivation. He reached the peak of foundation building at the age of ten and is expected to become the youngest golden elixir monk in the entire world of cultivation. He has a bright future. And behind him there is a venerable person who is in the stage of becoming a god. However, such a genius disappeared during a secret trial. Mu Cheng himself never thought that he would accidentally fall into a black hole and end up in a different world during a secret trial to find himself a natal sword. There is a natal sword, but in another world, he not only has to face the language barrier, but also faces a fresh father from another world. This father doesn't have a very good temper, but he always protects himself before danger comes. (The introduction is incompetent, please read and move to the text) (I'll add this quietly. If you want to rate it, just give it three stars. Try to score as low as possible)
