This process is extremely painful, almost equivalent to grinding every part of the body, flesh, and bones.
At the same time, this process also carries certain dangers, potentially causing damage to the body, resulting in injuries that are difficult to recover from.
However, once this stage is passed, it is considered a successful breakthrough, and the final stage is to stabilize the cultivation, without any danger.
The four stages take about three to five years, but during the breakthrough process, it is not necessary to go into full seclusion, only when establishing the Spirit Base, complete focus is required.
Zhou Tianci chose to go into seclusion in the western part of the Spirit Source Land because there is a Mystic Iron Ore Vein there.
Meanwhile, An Yuxing secluded himself beside the waterfall stone pool under the Spiritual Spring Mountain Plateau, where the water attribute Spiritual Energy is rich, not much different from the Spiritual Spring Lakeside.
