Li Yuan is an egg, a dragon egg brought here by the system. He is the child of the system's former host. Something happened to the system's former host. According to the provisions of the system's internal company agreement and at the request of the system's former host, the system took Li Yuan to other worlds.
The system stayed in some worlds for a while, and finally came to Teyvat due to an accident.
Then he met Zhongli, who was still Morax at the time, and made a contract with him, handing Li Yuan over to him.

Intention: The world is beautiful and I am growing up
