In 228 BC, the wind and sand on the border of a certain country carried the cold light of cold weapons, but were suddenly torn apart by a loud thunder-like sound - Lin Feng, a retired sniper from the Chinese Special Forces, carried an M16 rifle and 120 rounds of ammunition, and traveled through the electromagnetic storm to the eve of Qin's unification of the six countries. With a language barrier and a shortage of ammunition, he fought his way out of a desperate situation where he was almost treated as a barbarian. He used his fighting skills to save the herb-gathering girl, and defeated the horse thieves with 8 bullets. He was regarded as a "man of heaven" by the villagers, but he also attracted spies from Xianyang because of his abnormal "thunder method".
