Qin Xiao has been a soldier on the border of the Qin Dynasty since he can remember. His only reliance is the "kill the enemy and become stronger" system - killing the enemy can gain cultivation, skills, and physique. From the Body Tempering Realm to the Martial Emperor Realm, he single-handedly swept the Xiongnu and pacified the Baiyue. He was promoted from a small soldier to the Lord of Wu'an and became the most dazzling general of the Qin Dynasty.
Little did he know that every one of his military exploits was seen by Ying Zheng, the First Emperor of Xianyang Palace. Ying Zheng already knew that Qin Xiao was his own son who lived among the people back then, and secretly cleared away his political enemies and allocated resources for him, just to wait for him to be strong enough and the father and son would recognize each other. When Qin Xiao received the "Prince's" seal in the court hall, he realized that all his "luck" was due to his father's love.
After becoming the crown prince, Qin Xiao relied on the support of the system and Ying Zheng to kill Zhao Gao, suppress Confucian dissidents, capture Xiang Yu, collect Han Xin, and stabilize the Qin Dynasty; at the same time, he explored the method of cultivating immortals, broke through the shackles of the mortal world, and ascended to the immortal world. He found the art of resurrection in the fairy world, allowing his mother to return to the world and reunite with Ying Zheng, and the family of three was finally happy.
After that, Qin Xiao made a breakthrough all the way to the divine realm, took control of the divine power, transcended the universe, and stepped into the realm of the heavens. He led Ying Zheng, Han Xin and others to cultivate immortality together, planted the flag of Great Qin all over the world, and eventually became the emperor of all heavens who rules over all universes. Great Qin also became the most powerful force across countless universes.
