'Tianyu Villa' is located on a medicinal mountain with many precious medicinal materials. Ye Yu, the founder of "Tianyu Villa", is even famous for his superb medical skills. There is an endless stream of people going up the mountain to seek medicine. However, due to its excellent terrain, except for those with strong internal strength who can hold their breath to reach the top of the mountain, most people are buried in the mouths of jackals, tigers and leopards.
Ye Yu took on four apprentices. The eldest disciple Ye Yuze is Ye Yu's legitimate son. The second disciple, Ye Chenrui, was picked up by the owner of the villa on the mountain behind the villa, and no one knew his origin. He has high attainments in medicine. The third disciple Ye Yunxi is now the owner of Tianyu Villa. His father had a close relationship with Ye Yu. When he was hunted by the enemy, he left his five-year-old daughter and newborn child, the fourth disciple Ye Xi, in the care of the former owner.
Ye Yunxi's medical attainments are not as high as those of Ye Chenrui and Ye Xixi, but because of her own hard work in private, she can stand shoulder to shoulder with them. After inheriting the position of the owner of the village, she had always wanted her younger brother with more talent to take over her position, but Ye Xi was at an active age and wanted to leave the Tianyu Villa to travel around the world and experience the chivalry in the world.
