Review Detail of Biguy in Level Up Legacy

I didn’t know this was going to turn into a cultivation story. The stor is okay, but the mc is one dimensional with no personality. Having lived his whole life being looked down on, the moment he gets powers like everyone else, he goes from playing the hero to playing the villain in the blink of an eye. All the while never showcasing a personality. This made the story fall flat and became uninteresting, because you longer care why he wants to learn about runes.
