This was the side effect of the stone bead.
In fact, from Lin Yuelan's point of view, although the stone bead could save lives, it could also cause cancer. A new type of illness would usually only start to take effect in the later stages, and then death would follow.
While many doctors discovered this problem, they had no way to deal with it, let alone prevent it.
Therefore, unless it was a matter of life and death, ordinary people really did not dare to use stone beads.
Of course, stone beads were not something that ordinary people could possess.
The people or families who owned the stone bead also treated it as a treasure. It was to save their lives in a critical moment and then live for a few years, or even ten or twenty years. It was better than dying early.
Lin Yuelan asked, " Are you sure that your son's friend's heirloom is a stone bead? "
Chen Shanbiao was stunned. He thought about it and couldn't be sure.
