Late Tang Dynasty: from a Cement Wall to the World of Domination

Li Jun traveled to the outskirts of Changge County in the late Tang Dynasty. When locusts cross the border, they strip off the bark of trees and exchange their seeds for food. He fought his way out of the siege with a high-carbon steel horizontal knife, leaving only seventeen refugees around him. The mysterious shuttle hidden in a deep mountain cave allows him to travel between modern times and the late Tang Dynasty. But the only things that can be brought over are salt, sugar, iron and seeds - any finished products will be burned to ashes by the time and space channel. So he started by burning cement, making horizontal swords, and built a three-foot-wide cement wall with his own hands. Huang Chao's army pressed on the border, and Meng Kai's eight thousand soldiers besieged the city. He led eight hundred Cangtou troops wrapped in black scarves, and used lime, gold juice, night attacks and iron pagodas to hold on to the world in the troubled times of the late Tang Dynasty. While others were grabbing food and land, he was already building walls. When others attacked the city, his cavalry had already trampled the entire mountain road. In this game of chess at the end of the Tang Dynasty, he started from a wall.
