Great Ming: I Reveal the Future During the Hongwu Reign

In the fifteenth year of the Hongwu reign, an accident transmigrates Han Cheng onto the bed of Princess Ningguo, where they inexplicably spend the night together. But Princess Ningguo is Zhu Yuanzhang's eldest legitimate daughter, and the founding emperor dotes on her. When Zhu Yuanzhang hears the news, he flies into a rage and vows to have Han Cheng skinned alive to vent his fury.

With his life on the line, Han Cheng has no choice but to reveal that he is a transmigrator to save himself. Zhu Yuanzhang naturally refuses to believe him at first. But after Han Cheng demonstrates one miraculous skill after another and displays knowledge far beyond his era, even the suspicious emperor has to accept that the man before him truly comes from a world several centuries in the future.
