The legend begins with becoming a white deer.

Qi Ji transmigrated and was reborn as a rare white sika deer. Relying on the [Spiritual Essence Bead System], he could gain 1 Spiritual Essence Point every day after eating his fill. Thus, Qi Ji embarked on a legendary path.
The grandson asked his grandfather, "Grandpa, what is a fairy deer?"
Grandpa said, "The Celestial Deer is a legendary mythical beast. It can walk on water to save people, crush mountains to terrify demons, and with a single cry, ten thousand trees will swarm, burying thousands of enemy troops. It can also revive the dead and heal the wounded. For thousands of years, countless powerful rulers have fought for the deer but have failed to obtain it."
The grandson asked again, "Grandpa, can I see the fairy deer?"
Grandpa said, "I don't know. For thousands of years, only those with a special destiny have been able to see it. But we can go to the Fairy Deer Temple to burn incense and pray to Buddha. Legend has it that everyone who truly respects the Fairy Deer will receive its blessings."
