Review Detail of Kraxz in God of Investment

It started good, but as it goes on the story just plainly went downhill after him having money with his cheat the inconsistency of the mc and also his sister's character is very noticeable. It was introduced that the MC has strong will and drive due to him and her sister growing up as orphans as well as her sister being a considerate person. It just went downhill that after the MC got ample money he just became a beta MC being subjected to the whims of her sister which also became spoiled. Nevertheless it was such a good story but the character development is just.... well whatever good luck
