Shadow Demon World: Starting with the Chai Gang

On the fifteenth day of the eighth month, the blood moon hangs like a platter, and the Shadow Demons descend to suck blood essence.

Just after turning forty, chief physician Kong Xuanzhong undergoes a minor appendicitis operation on an operating table for the first time. When he wakes up, he has transmigrated to another world.

The wealthy live inside the city, can afford blood dragon wood, and unite to resist the Shadow Demons. Children practice martial arts from a young age, while the people inside the city regard the impoverished people outside as mere weeds.

The parents of poor children warn them from an early age not to practice martial arts. The stronger their blood vitality becomes, the more powerful the Shadow Demons they will attract, bringing disaster upon the entire village.

After Kong Family Village is thoroughly plundered once again by the Hungry Wolf Gang, Kong Xuanzhong, hiding in the underground passage, looks at the character template data in his mind and the countdown to the recovery skill below, [Status]. He decides to take his fiancée and younger brother and sell themselves to the Firewood Gang!
