I really enjoyed this novel for the first 200-250 chapters, you could even say it was my favorite novel of all time, but around the "war arc" the story became very stale, the same jokes were getting used over and over again, and the MC was just getting power up's from everywhere without any struggle(for example, before this he actually had to cultivate or had to struggle to get power ups), but around the war arc time he just started getting random power ups. All in all it became very boring to read and was becoming a chore, but i struggled up till around ch 350 and then just decided to stop reading hoping that it would get better in the future. So my question is, does the story improve? are the same jokes still used? is there any character development for the MC? is the MC still getting power ups with no struggle?
