Great Tang: Grand Marshal of the Army from the Start

Li Zhengyuan, Prince of Hejian Commandery, awakens the "Mandate of Heaven" System. Facing a fierce invasion by barbarians, he single-handedly forces the Tang dynasty to endure.

Li Shimin: "As long as Li Zhengyuan is alive, the Tang dynasty should be invincible!"

The Turkic Empress: "The realm may still belong to the Li family, but Li Zhengyuan is the only one I truly respect."

Princess Changle: "I will love only my husband for the rest of my life. Who even is that Changsun Chong?~"

Yuan Tiangang counts on his fingers: "The prosperous Tang dynasty lasted another five hundred years, and then somehow continued for another thousand?!"

Li Yuanzheng quietly takes a sip of wine: "System, bring me the world map! ..."
