Please Call Me Evergreen Immortal Fairy

Li Daoan accidentally traveled to another world, and there was a seed that traveled with him. The seeds fell to the ground and took root, sprouted, sprouted branches, and matured. Then they taught Li Daoan a technique. This technique not only comes with several profound magical powers, but also can achieve an 'evergreen immortal body' when practiced to the end, making it immortal and immortal!
