As she spoke, she watched Manager Xu's expression.
"My pill has a similar effect. However, it doesn't just promote the circulation of Spiritual Energy. It can also heal the meridian damage that cultivators of the Fifth Tier and above suffer from advancement."
A cultivator begins their Cultivation at the Initial Tier and gradually advances from the First Tier to the Ninth Tier. After the Fifth Tier, they are considered to be among the ranks of experts.
From then on, each advancement not only becomes increasingly difficult, but is also accompanied by surges of Spiritual Energy and physical damage from meridian expansion.
These are problems those below the Fifth Tier don't face.
Therefore, the period immediately after advancement is when an expert cultivator is at their weakest. They will spend several days recovering in seclusion, allowing their internal Spiritual Energy to stabilize and their meridians to heal.
