Spirit Interpreters had cultivation requirements, but they were only minimum requirements. For example, a Bright Eyes Primary Spirit Interpreter needed at least Integrating Realm cultivation to qualify, while a Control Intermediate Spirit Interpreter needed at least Exploration Realm cultivation, and a Haoran Advanced Spirit Interpreter needed at least Enlightenment Realm cultivation. These were merely the minimum cultivation requirements; they did not mean that anyone with that level of cultivation would definitely be a Spirit Interpreter of the corresponding level.
Only by reaching Enlightenment Realm cultivation and mastering an Original Treasure Formation could one become an Original Formation Master. As for a Grand Original Formation Master, one could still reach that level with Enlightenment Realm cultivation, but a World Original Formation Master had to be a Star Envoy. As for the highest-level Original Formation Celestial Master, one also needed at least Star Envoy cultivation. As for the number of Origin Tribulations, Lu Yin was not too clear. The Original Formation Celestial Masters he had seen were either Half-Ancestors or peak Star Envoys like Celestial Master Xiu Ming.
The Celestial Master Qiu Ling he had assimilated had cultivation at the level of Seven Origin Tribulations, very close to Celestial Master Xiu Ming's cultivation, though still somewhat inferior. That happened to make her assimilable by Lu Yin. If she had been a Half-Ancestor, Lu Yin would never have been able to assimilate her.
Assimilating an Original Formation Celestial Master was far more useful than assimilating a peak Star Envoy. At the very least, her experience as a Spirit Interpreter was extraordinarily valuable. Previously, the highest-level person Lu Yin had assimilated had only been a World Original Formation Master.
As memories surged forth, Lu Yin was still tremendously excited. He wanted to see the Original Treasure Formations Celestial Master Qiu Ling had mastered.
