During the Sui Dynasty, Shangguan Yi left his hometown and came to Xiaocheng to make a living in a tea house. He happened to meet Zhao Yunxi who was in Beijing to take the exam. Zhao Yunxi heard that the tea house business was very good, so he opened a tea house with Shangguan Yi.
In the same year, Yinglan, who lived deep in the snowy mountains, made up his mind to leave the snowy mountains because of his wife's instructions before her death. Finally, she came to Xiaocheng, but unexpectedly she met her only relative.
Later, a few more people came to the teahouse and became friends, but they were all looking for the ancient elixir White Moon Snow Lotus and started killing each other.
A few years later, there was a heavy snowfall at night in Xiaocheng, and the teahouse disappeared.
