In the ancient dynasty, Xie Mingyi, a little princess who was favored by the Queen Mother, insisted on marrying Lu Zhi, the son of an aristocratic family in her previous life, but ended up with the miserable ending of guarding the Kongyuan alone. Reborn as a teenager, she vowed to cut off her old relationship, wear armor and carry a sword, and become a chess player.
