I recommend "Servant Knows My Mistake: Lord of War Begging for Spare" to you. It's an ancient romance novel. The female lead, Yun Changge, had transmigrated into a little palace maid and accidentally provoked the legendary Eighth Prince of the War God! In order to survive, she tried every means to become the Empress's palace maid, but the Emperor looked at her strangely. In order not to become a resentful woman in the palace, she had to get close to the Eighth Prince, but the two of them became enemies. For five thousand years, they lived and died together! I hope you like this recommendation. Muah ~
