Hang on, he is doubting the knowledge from the system n not expecting it to be something amazing n powerful even though he himself was able to use the very same knowledge to retrieve a soul from the underworld?? Let's not talk about the soul but those fertilizers that can instantly grown a plant to maturity n bear fruit within a minute even if he is the one planting it.. Wtf is wrong with his thought process, sure go be a mortal but everything given by system is o.p okay 🤬
