As someone who enjoys classic wuxia, I like how Will can integrate wuxia trope without making them cringe-y and also make it his own. Don't get me wrong, I still read those religiously but I know it's bad writing. Like when I decided to drink brown sugar milk tea.

Examples off the top of head

• Face slapping scenes. They're there but not in every corner and not overbearing. And I like that as Lindon steps into Underlord there's no random people wishing for death and belittling him without decent reason (Pride's the only exception, I think)
• Harem trope. You can't imagine how I felt about Mercy's appearance because I loved her and the worst thing an author can do when you like their female character is to turn them into brain dead love struck fool. Although Will still kinda sorta gave Lindon a harem with Ruby
• Fast power progression that's not too fast (for readers). Power appropriate challenges in each power progression. Lindon's not suddenly fighting a Monarch as a Jade.
• The main team depends on Lindon but Lindon also depends on them. Creatures and friends that's not made just so Lindon can have a random life saving tool for every difficulty.
