In the fourteenth year of Yongle's reign, Ji Gang, the commander of the Jinyi Guards, was executed. Before his execution, he said something to a small household:
"I just saw things I wasn't supposed to see."
Shen Zhiheng was demoted to the compilation office of "Yongle Dadian" and was ordered to verify the strange things in the world.
The first case is the case of the demon cat during the Hongwu period - a black cat with arrows hanging in the air, eyes like red torches, and a life of three thousand years.
The second one is the passing of Yin soldiers during the Jianwen period - the sound is like thunder, all witnesses are dead, and the ghost army on the city wall.
The third item is Shen Wansan's treasure trove—copying all things, with unknown origins, and hiding secrets from the universe.
Shen Zhiheng searched deeper and deeper, and found that every strange thing in "Yongle Dadian" pointed to the same answer:
This world is not what we think it is.
And his father, who has been missing for many years, has already hidden the truth in his name.
