Ye Chen wanted to destroy the dragon's nest and the surrounding Ten-Thousand-Year Soul Dragon Herbs.
Each Ten-Thousand-Year Soul Dragon Herb and spacetime artifact signified the birth of a Creation realm expert in the Soul Race or Hall of Souls.
Given the status and power of the Hall of Souls, they might lack spacetime artifacts, but not Ten-Thousand-Year Soul Dragon Herb. However, they required these herbs in order to break through, as they allowed their divine souls to transform, without which, their divine souls would not be able to use the power of the spacetime laws.
Even if they broke through using spacetime artifacts, they would at most be half-step Creation realm experts. Since they specialized in soul techniques, the inability to use the power of spacetime laws meant that their main source of attacks would be weakened.
Therefore, the Ten-Thousand-Year Soul Dragon Herbs were extremely important to the Soul Race.
