 Instead of "being cool" I actually find it dumb he kept rejecting good sects and teachers who are much more stronger knowledgeable and connections. You might think it is cool he is "going through the hard way" but in reality he will learn more with stronger teachers and people who are more knowledgeable get better pills because his goal is to "learn faster"  you need to get any opportunity you can get to be stronger and faster and to prove my point, later he met to guy he saved again (the guy who went to the poison sect) and realized the guy got much more resources, books to learn from, pills, teachers at the top 10 demonic sect
