Floch does indeed die. His fate is a significant plot point in the manga's storyline. The circumstances surrounding his death add to the overall tension and drama of the series.
Well, it could have completely changed the course of the story. Maybe he would have used his powers more strategically or made different choices that affected the outcome.
I recommend "The Rebirth of Hong Kong's Dragon and Tiger Martial Artists" to you. The main character in the book, Chan Jiale, traveled back to 1985 and became a substitute for Chan. He constantly challenged difficult movements in the filming of movies and became an outstanding actor step by step. There was also a plot of the Baby Plan in the book. I hope you like my recommendation. Muah ~
