The silver dragon mark appeared quite mysteriously in Lu Li’s Soul Pond. He speculated that this had much to do with the animal tooth pendant and… it might have just converted into the mark!
When Lu Li was building his Soul Pond, the animal tooth pendant had gone missing. He had scoured the entire room for it but nothing turned up. Also, during the process of constructing the Soul Pond, Lu Li felt the animal tooth pendant glared and warmed up, and he felt there was a dragon shadow moving in his blood.
This might be what had happened—the animal tooth pendant entered his body, turned into a silver dragon mark, and integrated into his Soul Pond.
