I Was Reborn at the End of Qin Dynasty and Established the Foundation of Han Dynasty

Xin Yu was delivering takeout on a snowy day and was hit by a car and died. When he opened his eyes again, he unexpectedly returned to the 29th year of Qin Shi Huang's reign and became an old beggar by the reeds in Bolangsha. There is no system, no cheats. Before he could recover, he was about to be beheaded. At the critical moment, relying on the little historical knowledge in his memory, he gave the First Emperor a suggestion to prepare more auxiliary vehicles. As a result, Bolangsha's iron cone hit the wrong target. He saved the life of the First Emperor and himself. I thought I could survive, but before I could take a breath, Zhao Gao sent people to kill him. Dozens of refugees were killed in the blink of an eye until only a few remained. Blood stained the reed roots. Xin Yu looked at the lifeless corpses and finally understood: In this world, if you don't eat people, people will eat you. Then stop living! He took the few remaining refugees and huddled them together like reeds. There are no soldiers and horses, no food and grass, only a brain from two thousand years later, and a group of brothers who are not afraid of death. But those princes and generals didn't know that Luweidang, an old beggar who was about to starve to death, was rewriting their fate one stroke at a time. The reed looks weak, but the stronger the wind, the less likely it will fall. The copper wall and iron wall of Da Qin started from that reed and opened the first crack.
