The story isn't bad for what it is. There's not much character progression after the transmigration. The progression of the MC's strength has a problem. There's free attributes that the MC constantly earns. Yet we are left wondering if he uses them and how he allocates them. There's also chests but the author does not consistently tell us what is in the chest after they are opened. So you are left contemplating the MC's stats and load out. It is frustrating after a while. The author definitely isn't fleshing out the details.
