In the first year of Tianli, Haozhou.
A soul from more than six hundred years later wakes up in a dilapidated adobe house. He found that he had become a farmer in the late Yuan Dynasty, and Zhu Wusi's family lived next door.
One night, Zhu Wusi's wife gave birth to a baby boy, named Zhu Chongba. He knew that this baby was the future Hongwu Emperor-Zhu Yuanzhang.
He also knew that this emperor would kill meritorious officials, set up royal guards, peel off blue jade and turn it into grass, leaving countless regrets for the Ming Dynasty.
He decided to be a good neighbor from today on.
From teaching Zhu Chongba how to write the first word "", to giving him "Sun Tzu's Art of War"; from advising him "not to take the lead, not to be greedy for merit, and not to kill and surrender", to helping him save Zhu Biao, untie Lan Yu, and cut off the vassal king - a neighbor who traveled through time spent twenty years trying to change the fate of a dynasty.
