Within the Immortal Stones, jade is revered and highly costly. It is a commonly used material for Immortal artifact refining. And in the Immortal Realm, there exists a mystical mountain called "Mount Heshan," known for its jade resources.
The Penglai Immortal claimed Mount Heshan for himself, transforming it into Tashan Stone.
None of the immortals dared to challenge the Penglai Immortal, fearing that even if they won the competition, their own immortal artifacts would be damaged by the Tashan Stone, leading to a loss outweighing the gain.
Seeing the Tashan Stone was not put to use, the Penglai Immortal bestowed it upon the Penglai Fairy Island left in the Nine States, serving as the grand treasure of the sect.
When Jiang Li threw a punch, the Tashan Stone was refined once again. The stone material was compressed and metamorphosed, elevating the hardness of the Tashan Stone to a higher level.
