In the ninth century BC, the Zhou royal family's war horses were weak and the paint on their chariots was peeling off. The Sixth Division could not muster 3,000 useful horses.
To the west of Longshan, a group of survivors of Shang Dynasty who were exiled from Shandong by Duke Zhou were raising horses for the Zhou people under the sword of Xirong. They are people of Qin, their status is vassal, their ancestor god is Xuanniao, and they only have three things to survive: horses, salt, and knives.
Ying Ye, the lowest-ranking horse slave in Qin Yi.
He has an ancestral "Book of True Horses" that can make war horses faster than military cavalry; he has a gold medal in the shape of a bird of prey, which hides the blood oath of winning the Qin Dynasty for seven hundred years; he has a bronze whittling knife, which once cut open the belly of a dying mare and took out the mysterious colt that changed the fate of the country.
From Qingshui Qinyi to Haojing, on the 700-mile Longshan Road, he led 700 horses to ambush Xirong and cut off the legs of hundreds of soldiers on the narrow cliff road; at the Zhou Dynasty Villa, he sprinkled wine on the ground in front of the minister Ji Shuo and offered naked sacrifice to the God of Shang; at the Shenhou tent, he held half a tiger talisman and fought his way between the Wolf Head Banner and the Kuilong Banner.
This is the eve of the rise of the Qin people.
There is no myth about the destiny black bird descending to give birth to Shang. There is only a horse slave crawling out of the bloody mud, chewing up the word "vassal" and swallowing it in his stomach, and then spitting out a knife that cuts through the spring and autumn.
