Lin Yan, a modern mechanical engineer, accidentally traveled through the late Warring States period and became a battlefield remnant.
He suffered broken bones and was in a desperate situation, but with military knowledge and military thinking that transcended the times, he rose up against the odds in troubled times.
He improved his crossbows, forged iron armor, and created a new formation. He used 500 warriors to defeat the 8,000 Zhao army, and shocked the northern Xinjiang in the first battle.
Entering Xianyang, he met the First Emperor, took control of the world's weapons, made repeated crossbows, established the country's system, and strengthened its military equipment.
When Da Qin had a magical weapon that transcended the ages,
When the Six Nations cavalry met the modern military formation,
Lin Yan used the hands of the God of Craftsman to cast iron and blood to strengthen the Qin Dynasty, sweeping the world and wielding power in both the government and the public!
