The difficulty here lies in the Divine Soul!
Whether it is a Cultivator, a Mechanical Transformer, or a Martial Artist, being able to possess such heaven-defying methods at Tier Five is due to the existence of the Divine Soul.
To achieve Tier Five, as far as the Martial Artist System is concerned, one must not only enhance their vitality to the extreme.
Ensuring their vitality can support them in stepping into this realm.
More importantly... the Divine Soul must be resilient enough!
If the Divine Soul is not resilient, it cannot be fully integrated into the body, and there is even a high possibility that it will be dispersed by the intense vitality within.
Therefore, there is a certain degree of danger when breaking through Tier Five.
If the Divine Soul is damaged, not only will the foundation of Martial Arts be destroyed, but even the whole person might become a fool.
There are only two ways to enhance the Divine Soul.
