When Zhou Yan, a graduate student in the history department, woke up from a coma and found that he was Sheng Yong, a general in the early Ming Dynasty, his first thought was: I am going to die.
As an expert on Ming history, he was very clear about Sheng Yong's fate - he fought a bloody battle for Emperor Jianwen with King Zhu Di of Yan in the Battle of Jingnan, and was ultimately defeated and died. Now, he is standing at the center of this historical whirlpool.
Relying on his foresight of history, he saved the day from danger time and time again on the battlefield and managed to get his way in the court. He got acquainted with the kind but gentle Jianwen Emperor Zhu Yunwen, and became the young emperor's most trusted general; he also saw the talents and strategies of Yan King Zhu Di, and secretly guarded against each other while cherishing each other.
When the battle of Jingnan burned across the Central Plains, Sheng Yong faced the most painful choice: should he follow history and surrender to Zhu Di, who was destined to win, or should he fight to the last moment for his confidant Zhu Yunwen? Should he stand by and watch his comrades who are destined to die, or should he fight to change their fate?
He chose a middle path - in the cracks of history, saving the people who could be saved and changing the things that could be changed. When the smoke from Nanjing's destruction dissipated, this time traveler who knew everything stood on the devastated battlefield and finally understood: some fates can be fought against, and some histories must be accepted.
This is not a story about changing history, but a story about sticking to one's true heart amidst the torrent of history.
