Review Detail of Kayle_Mighty in Monster Paradise

This novel is quite decent but after a while it got annoying with him always hiding his abilities and somehow always shaking his head whenever he gets underestimated. He's always hiding something. It's fine when he doesn't use his real name since he doesn't want purple crow to chase him. It's also ok to hide the monsters, that's his little secret. But for the people who do know him, why hide your strength? Why hide the fact that you're "sword genius?" When he enters the ruins I became so annoyed with Yeyu and li liang always saying something that shows they think hes weak and the mc is always "smiling helplessly". The funny thing is people always notice there's something special about him but they still go the route of underestimating him, just so he can show his abilities later and then they act surprised. Why can't these Chinese authors just write decent characters, smart ones that actually try to find out how good you are before saying "you're too weak" instead of immediately underestimating someone?
