The terrain of the Heavenly Medicine Blessed Land is fan-shaped; it becomes narrower the deeper one goes. The seventh region can already be considered deep, yet it is still about half the size of Daozhou.
The escape technique of the Qilin Undying Medicine is too strong, and being an earth-element medicine, it can swiftly flee upon contact with the ground. Even the Earth Spirit Great Saint with the Later Earth Sacred Body cannot catch up, let alone others who can only trail from afar.
Su Han has been following the team for three days, but except for the first day when he saw the Qilin Undying Medicine, he hasn't seen it again.
Not to mention the Qilin Undying Medicine, he hasn't even caught sight of the Earth Spirit Great Saint since then, merely encountering the Buddha Great Saint occasionally. However, he's not anxious; the Immortality Medicine isn't easily captured, and impatience won't help.
