He originally wanted to choose the most difficult option and get the best reward after becoming stronger, but he discovered halfway that this system seemed to be poisonous. The more difficult the option, the worse the products would be. Doesn't this force him to be a steady person? This is not good… No, that's great! … This book is also known as "The Magic Box of Vitality", "Becoming Stronger, Start with the Magic Box", "Start with a Random Magic Box", and "This Magic Box is Full of Vitality".
