Sister Li Came Outside the Door.

After inheriting the hotel left by her grandmother, Li Meng, an abandoned daughter of a wealthy family, accidentally discovered that she could connect the past and present with a jade pendant here. She rescued the ancient Ling King Jiang Shiyan, exchanged modern medicines, grains and other materials for antiques, accumulated wealth, and got rid of the entanglement of her eccentric father Li Jianguo and her selfish sister Li Yu. During this period, Li Meng helped Jiang Shiyan fight against the prince and the barbarians, promoted modern agricultural technology, and eventually became an upstart in the business world, and gained a deep friendship with Jiang Shiyan.
