If there's one thing I had to criticize about this series so far, is the introduction of "the system" and then after its relevancy has passed its kinda just there in the background.
Its there as a plot device to magically heal his mother and his back issues, the main reasons the author gave the reader to symphasize for the MC at the beginning of the story, but after that it hardly ever shows up again and its kinda just presumed he's using it in background to excel further and further.
Its like yeah it exist, and unless some deux ex machina problem comes up again it won't be at the forefront of the story. Its not that different than other Korean Manwha in this genre in that regard, the story overall is just okay.
