That special resource could only elevate his realm by one level, but was unable to raise the realm of Langya Saint Lord by one level.
It made sense, after all. He was merely at the second level of the super realm; to advance one more level would only bring him to the third level of the super realm.
Whereas Langya Saint Lord was already in the upper echelon of the Saint Lord Realm, and the next step up for him would be Peak Saint Lord.
The resources required by the two were undeniably on a different scale.
Nevertheless, True Martial Saint Lord only spoke such words previously in order to persuade him to agree to take over Immortal Origin Holy Land.
Therefore, his conflict with Langya Saint Lord wasn't significant, whereas his conflict with Chu Lee was, perhaps Chu Lee also wanted that special resource?
