It is said to be an "accident" but it is no accident; Mo Yan orchestrated the whole thing. She had the Hidden Guard pose as an ordinary person and tell the Fang Family that they were in search of a Noble person compatible with their horoscope to be a bride, and Mo Yongxi was immediately tempted.
Mo Yongxi had a bad reputation in the village, and no one from her own village or the surrounding ones wanted her as a daughter-in-law. As her age kept increasing, it was impossible for her not to be anxious. Now that a fine marriage proposal fell from the sky, how could she not grasp it firmly?
While Mo Yongxi tried every means to ingratiate herself with the elders of the Fang Family, Mo Yan had the Hidden Guard disguise himself as a celestial-looking Taoist, divining for the whole Fang Family. He only mentioned that upon finding a person compatible with their horoscopes, the Fang Family would certainly prosper and their wealth would flow in abundantly.
