After transmigrating to another world, he becomes the second son of Emperor Qianyuan of the Great Qian Dynasty.
As the second prince, who is useless at everything and looked down on by the world, Jiang Cheng had planned to lie low. But then the late emperor, seeking to practice an ancestral secret art, had to feign death and enter seclusion for three years.
To reclaim the throne when he emerged, the emperor deliberately passed it to Jiang Cheng, the most worthless of his sons.
Fortunately, Jiang Cheng activates the Strongest Emperor System.
He summons Han Xin, the Immortal of War, and gains a troop type: the Immortal of War Army.
He summons the famous general Yue Fei and gains a troop type: the Beiwei Army.
He summons Kongming, the Sage of Strategy... One after another, legendary figures from Chinese history come to serve him of their own accord.
Three years later, the late emperor returns to reclaim the throne.
Behind Jiang Cheng stand countless strategists and a host of renowned generals.
“I have already ascended the throne. Why would the late emperor commit treason?”
