only that MC's brother turn into a severe siscon. Understandable though, if you have a cute little sister that is kind, smart and attached to you, you ain't gonna give her to some random rascals. NO ROMANTIC element between MC and her brother, it's purely familial affection.
even her friend suffered because of rencarnation departement screwed up and gained a very embarassing power, at least his gender doesn't change and his appereances doesn't become uglier
she work as a waitress in a bar where most of the attendant are rough adventurers. You can guess the rest
MC teach magic to his niece and messed up, his niece become vegetable ever since. He make a deal with an elder from a martial arts sect to cure his niece, at the cost of transmigrated to another world to protect the elder's great grand daughter for his entire lifetime. MC transmigrated and become a loli on the top of that. Here MC meet some new characters, friend and foe and has to deal with threat from other hostile forces as well some politics inside the sect because apparently the sect opinion is rather divided on deciding the sect's current lord. (In vol 2, especially s (he) has to deal with insiders)
Vol 1 focused on how MC accostumed to the new world and establish his/her sect reputation (Another sect killed one of the elder of MC's sect, MC take revenge by directly attacked the killer's sect headquarter and defeat the sect leader in a flashy manner)
Vol 2 will introduced new character that will become MC's sect aide. MC has to deal with insider here. Not much fight here
Vol 3 involved fights a lot. MC has to deal with someone that far stronger than him/her.
As the title suggest, MC has no dignity whatsoever (even though s (he) supposed to be respected), because of her/his easy going and somehow punchable attitude, and ended up constantly scolded by the sect current leader, Qi Qiqi. MC acted like an idiot but actually, s (he) by no means a stupid person, s (he) just lack common sense sometimes as s (he) just transmigrated.
MC is not OP (as the novel shows that there're some people that actually far stronger than her/him) but VERY strong, enough to be called as "walking natural disaster" by other people. Enjoyable so far IMO
