it is due time now, muzan need to die now or this manga might fall off the popularity, too many casualties for muzan to survive this, have him die and end this series on a good note.
seriously tho, this mc talk a lot, is it possible that the people in immortal world attacked him not because of book of heaven but because he talk a lot?
i won't fight, but if my blabla is hurt, it's different matter, man this guy can just make up any excuse so he can start fighting anyway, so why botheR?
