MC is invited to the direct disciple ceremony of this "villain junior brother" (reminder: after he got kicked out of the sect), he goes there, his Original Master is like "see I gave him what you wanted for years haha". Here, again I failed to comprehend why they add a master/disciple contract broken in chapter 1 if he never was her direct disciple but simply some named disciple apparently...

MC and his new Sister literraly slaps some his old senior sisters in their own sect and no one say anything. Again, I fail to see how this is possible in a cultivation world / sect... Its like going in a gang turf while wearing another gang's color and attacking their members... I was expecting some Elder or Mc's OG master to say something but nope.

Anyway, they try to use MC's old formation that only he can setup to give some swordsmanship comprehension boost to the junior brother (something he did in the past before the story started for his OG Senior sister), the guy is about to die as it turns out the formation is one-time use only. So some slight facesplap ensue, where they must asks MC's help to fix the formation, he refuses, they tries to force him but get scared because of MC's new master reputation (she's feared by the whole continent) and the intervention of a well respected Sect Master from another sect.

So MC could let the guy who he knows is a demonic cultivator dies (which never cross his mind even though apparently being a demonic cultivator is huge bad thing in this continent), or saves him and gets some advantages. He negotiate for one treasure and also for 3 of his older "Senior sister" to kneel and beg him which they originally refuses (Again proving that faces is important in the setup in theory...). He could have asked to use the treasure mentionned in chapter 1 to clean his reputation but never thought about it either, but this part is still believable.

Then after he helps the Villain, MC's OG master wants to force him to give back the treasure she gave him just before. Still in public, in front of all the others sects present. So suddenly, she again throwaway all her faces even though she is supposedly well respected, and forget her fear of MC's new master. Guess what ? Mc's new master arrives and battles his OG master, when she gets tr*shed the Villain is like "let's resolve that by having me duel MC". And no one thinks its nonsense, the guy would have been dead without MC's helps, they can't force him to give back the treasure and now wants to duel him to get it. Ah yes, I'm winning my fight against you to protect something that is rightfully mine from our trade, but let me accept your fight proposal to have our children fights and decides the outcome... Seems logical, can't argue.

Anyway the duel is even more nonsense (which gets interrupted by an unrelated character the stroll in and his like "oh let me duel you both before lol"), that ends up in Villain losing and saying "oh its just a sword fight, its not a real fight", ah yes, fighting with swords in a cultivator world is not a real fight, my bad I forgot that's not like 90% of cultivators uses swords and you just had a boost to your swordmanship for this reason.

And then MC's gets back to his own sect, it's revealed than while the duels were ongoing, MC's OG master sent some elder to steal the treasury of his new sect, and his new master stole the old sect treasury.

So, I'm to assume, that those guys who fear MC's new master because of her strength (which she again displayed just before), went and stole her sect treasury, and that they were able to do it easily, where are the sect's protective formations overpresent in this kind of stories ? (It goes both way, how was his new master able to steal the treasury from his old sect without no one detecting it, same thing, no formations ? No Protectors ?)
