Review Detail of DeeJack in Five-Year Old Prophet is Pampered by Ten Brothers

First of all, this is a "system" novel, which wasn't even mentioned in the synopsis. The MC acts like an idiot, which is completely normal for a 4 years old, but then in the next paragraph the author explains how she's a genius, she knows about financial investment, she built hotels and restaurants etc, which I find quite difficult, even with a system. I didn't feel the story that interesting, but I didn't read a lot of chapters so I won't be too harsh.
