Best Friends Wear Books Together, Eat Melon and Laugh Together Haha

[Eat melon + dual system + time travel + voice + funny + have CP] Jiang Xiaoxia and Ji Ran, two college students who traveled through books together, directly unlocked a new life in ancient times. She transformed into Jiang Xiaoxia, the legitimate daughter of the Marquis Mansion, and was bound to the Melon-Eating System, while Ji Ran was dressed as the legitimate daughter of the Prime Minister's Mansion, and was bound to the Counterattack System. The two of them relied on the system to make them happy, with melons, good looks, money, and leisure, and they directly reached the pinnacle of life. However, Jiang Xiaoxia was directly made a female official because of her voice, and from then on she began her "cow horse" working life. However, fortunately, there is a melon-eating system. Although it may not be considered work, it is also a lot of fun. [The host, the Minister of Civil Affairs, got drunk and thought his son was a beauty] [Wait a minute, the host King Yi thinks the prince is his love rival] [Host, that minister actually wore women's clothes to make his daughter happy] However, due to the appearance of these two people, the original storyline was completely changed, and the big boss behind the scenes gradually emerged.
