To advance to the Foundation Establishment, there are four challenges for a cultivator.
The first challenge is the Physical Body.
When channeling the Spiritual Qi of Heaven and Earth into the body, a cultivator's physical body must be robust!
If previously heavily injured, left with hidden ailments, or the foundation is damaged,
it's like leaving vulnerabilities in the body, making it hard to convert Spiritual Qi when channeling, causing poor circulation of energy and blood.
Moreover, the physiological functions of elderly cultivators decay, and the decline of energy and blood also affects the process.
Of course, age is not the primary factor.
The key is the perfection of the physical body.
"I practice the Divine Hidden Sea Technique, a Water Technique, and coupled with talents like Iron Bone, Sea-Covering Thunder, Immune to Poison, and Silver Hook Poison, my body is perfectly flawless, comparable to Foundation Establishment."
