Lu Xuan seemed to not care about the longevity grass at all!
This was because Lu Xuan was still young. For him, the realm he could reach was endless. Thus, he did not need things like the longevity grass to add a few more years to his life.
However, the longevity grass could save the lives of elders who were in the Divine Transformation Realm.
Even if the longevity grass was not refined into an alkahestry pill, swallowing one could still add several years to their lifespan.
Although only a few years didn't seem that significant of a change, those who were on the brink of death were willing to live for even a few more days. Of course, they would've wanted to live for more years!
That lone Cultivator expert was tempted by the longevity grass!
