The story is fictitious and should be viewed rationally.
Time travel, to put it bluntly, is to live the life that has not been lived again.
Interpol Wei Ning traveled through time and became the Imperial Guard of the Ming Dynasty, becoming the personal bodyguard of the second prince.
Ten years ago, a prophecy of "Feng Ming Chao Huang" triggered an unsolved case in the palace. Now officials related to the old case have died mysteriously one after another. In the harem, the beloved concubine will do whatever it takes to help the third prince ascend to power; in the court, undercurrents of forces from all sides are surging.
Wei Ning used modern criminal investigation knowledge to break the game, but found that he had already been involved in a larger chess game.
In this game of chess, the winner takes all, and the loser takes all.
