When Li Hao woke up, there were only twelve old, weak, sick and disabled people left around him. The Jiuli tribe's flag was trampled under Ji Heng's feet, and his brother Chi Lie's blood stained the wasteland. Heaven issued a bloody warning: Any attempt to change historical facts will accumulate "sin karma", causing five thunders to strike and the body to be burned by karma. But in his mind, an ancient space slowly opened - magical weapons, provisions, and prescriptions were refreshed every day. The first Mo knife broke through the boulder, and the first bag of seeds was scattered into the scorched earth. Using modern special forces training methods, he allowed the remaining soldiers to learn ambush in three days, master battle formations in seven days, and train an elite night attack team in half a month. However, food and grass were always at the bottom, so he set his sights on the Central Plains imperial examination: to obtain fame, he could obtain heavenly merits to offset his sins. In the examination room, he shocked the government and the public with his article "On Jiu Li Not Barbarian". The foreign boy slapped the dignitaries in the face, but the prince Ji Heng sensed the threat. The army pressed on the territory, and the evil demons of the void took the opportunity to invade, feeding on historical resentment, triggering a great famine and a wave of alien beasts. Li Hao opened the box and found "hybrid rice technology" and "devil-breaking crossbow design", but the punishment from heaven came at the same time - the fire of karma burned his meridians, warning him to stop. Wu Ma sacrificed his body in the formation to gain some change for him: "Young Master, Jiu Li's will is difficult to pacify, you come to pacify it." Li Hao gritted his teeth and swallowed the fire of karma, looking at the thirty new city walls in southern Xinjiang, his eyes ignited with the light of reversing the way of heaven.
