The members of the Fengyun clan had been checking on Tang Yu's background ever since she came into Fengyun Manor, but none of them were successful.
It turned out that Tang Yu had never gotten onto anyone except the people in the Tang family. Moreover, Tang Yu was secretly apprenticed to the lady of Fengyun Manor. Hence, the Tang family was not aware of it.
Back then, the master of the Tang family—Tang Luo, brought a woman who had lost her memory back to the manor. As the Tang family was afraid that this woman might ruin the Tang family's reputation, they had covered it up, even the servants in the Tang family had no idea that there was such a woman staying in the manor.
Moreover, Rong Yan had never left the mountain behind the manor. Hence, the people of Fengyun Manor could never find her.
However, Feng Ying did not give up checking on Tang Yu as he believed that he could ultimately find the lady of the Fengyun Manor.
