Hundreds of years later.
Morax rescued many of Meng's fairy beasts, including Mandrill, and discovered Mandrill's incompleteness. He spent a lot of energy to treat Mandrill, removing the part burned by the spell and then filling it with the flesh and blood of the god, and helped the bird reshape its broken wings.
The stars change and the sea changes. The two secretly fell in love with each other for various reasons. It was not until a thousand years later that Yan Shen abdicated and took the name Zhongli. Then they gradually opened Mandrill's new house, and one person and one immortal lived a happy life in Liyue Port.
Concept: The implicit romance unique to the East, extremely stretched and hard to express. Until the sweet spring called love fills up and overflows, people with low self-esteem and sensitive people dare to speak of love.
