Let me laugh
why would her favourably increase? why didn't it decrease the moment she found out how he wasted the opportunity she had laid out for him? The way he did it was definitely a lost of face for her. And we all know how they treat their face/reputation in these types of novels, especially cold and indifferent eccentrics like her. If this mc were to ever meet an opponent who is similar in combat power, without luck ( plot armour ) he would 100% die. cultivators always fight, even those who are considered prodigies have been conditioned to fighting since an early age. he has, up to this point into the story, always been overwhelmingly more powerful than his opponent. even if he meets someone who is inarguably weaker than he is, he will be at risk of dying no matter how cautious he is due to his lack of actual combat experience, so long as that someone isn't one he completely eclipses in power. even now it takes a long time for him to advance, there has to be a point where just sitting in one place and doing nothing but training with no extra boost won't be enough. And by that time, everyone at his level that he has to compete with for opportunities will have tens of thousands maybe even hundreds of thousands of years of fighting experience. And the higher the cultivation level, the more tricks they'll have up their sleeves. Him having gotten to where he is by little virtue of his own effort and with no struggle or hardship at all compared to others at that level, will be completely outclassed by them. It'll be like a p2w player meeting an actually good high level veteran player in a game. People at that level have gone through multiple life or death situations and can remain calm in them to make the best decisions. Meanwhile the mc was flustered even before attempting to fight the beast that was chasing after him. he has never attempted to adjust himself to his new power and has no idea how strong he actually is.
