I recommend the "Cannon Fodder Survival Manual", a classic Xianxia novel. As cannon fodder, the male protagonist was destined to experience all kinds of hardships. Not only did he have abdominal pain, but he also had to face all kinds of difficulties and challenges. However, he used his own hard work and wisdom to gradually obtain more resources and strength. In the end, he resolved the crisis and became a strong person admired by everyone. I hope you like this fairy's recommendation. Muah ~😗
