It's really good, especially if you are looking for some realistic development. It's not like one of those where MC will always go for adventure and somehow gain all the treasures thanks to plot armour. This MC is how I think I'd be if I could improve without taking unnecessary risks.

LIKEOne thing I personally found unrealistic is that every opponent he faced had his supreme treasure of the counter element of the MC. when he was relaying on the ghost at the beginning he faced only cultivators of fire element or had lightning treasure, when he relied on red emperor he face opponents of water element or had water treasure and when he faces opponents him self, they all magically had a supreme treasure stake made of wood to counter his earth element. he never had advantage of element, except he had the advantage of numbers.
