alright thanks for the answer, i think this helps, i atleast got a couple ideas like this, i think you should add some tips for the next ending in after one of the beastwave ending like for end 1 the dialogue could go like, whit your qi you managed to barely sustain a small defensive formation around yourself inside the now abandoned sect, you are the only survivor, if you had more qi you could save more (obviously whit some better writing) and so on until you get to end 3 whit the tip saying you need spmething more if you want to save the city not just it's inabitants
this could also explain why you can fight back against the beast wave and survive while having just 2 qi and a attack power in the 300s while you can't even survive whit a attack power of 2000
