Seeking the name of a martial arts novel

He only remembered one plot of a martial arts novel he read in high school: His girlfriend was captured and the male protagonist was forced to give his girlfriend a pill that increased his power. The other party did not know how to use it. The truth was that it was a magical pill wrapped in poison. At that time, the protagonist was very happy because he happened to know how to use it. It seemed that it was left by his master. He used his internal energy to remove the poison and then gave it to her. However, she did not know and accidentally hit him. The male protagonist was waiting for death…
After that, a different person told her that she could increase her power by regulating her breathing immediately. She was heartbroken…
Also, he learned martial arts in some ancient cave on the cliff. He has a senior brother who is extremely respected I think it's called immortal or something In any case, he is already a god-like figure in the martial arts world
that's all
