Gu Zhen Ren
Sooo, flower wine monk new inheritor would be a weak lvl 1 gu master. MC gets exactly what he wanted. I feel his previous life would make a better story at this point with all the struggles but it’s still early and I hope the MC doesn’t get everything too easily.
I think it makes sense that the flower wine monk did a test that so far is easy enough for a low level person like the mc to complete as remember there is hardly any level 4 gu masters around here and plenty of level 1 and 2 so if he made it difficult his avenger may never come to be. If the person is strong they can pass easily but if not he left behind ways for them to grow into a strong enough fighter to fulfill his revenge. Also if the person was already strong why would they need his inheritance to be able to act out his revenge only someone weaker would need it. He has to think of the future of who may discover it so makes sense.
