I, the Prince of Qin, Will Guard Hangu Pass for Ten Years!

"The fifth prince Ying Yu will go to Hangu Pass immediately and guard Hangu Pass. If the fifth prince is summoned, he will never return to Xianyang!" Originally, Ying Yu thought that this would be the beginning of his magnificent career, but he did not expect that Da Qin had so many talents that he did not leave Hangu Pass for ten years. Fortunately, Ying Yu obtained the sign-in system after traveling through time. The longer the time, the richer the reward! "Sign in for one year and gain tremendous strength!" "Sign in for three years and get three thousand Snow Dragon Riders!" "Sign for five years and get 10,000 tiger and leopard knights!" "Sign in for ten years and get the Eighteen Riders of Yanyun!" I originally thought that I would have to kill all the generals of Great Qin before I could get out of Hangu Pass. But he didn't expect that ten years later, Qin's 300,000-strong army would be trapped in Handan. Bai Qi had not left, and Wang Jian had not yet appeared. He was the only one in the entire Qin Dynasty who could ask for help! Ever since, Ying Yudong came out of Hangu Pass, and the name of Overlord resounded throughout Liuguo! Da Qin actually started unification in advance! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
