A determined voice echoed. "I use the Willpower Rune as an oath to become Class 2 Creation Master Lin Yuan's retainer. I shall solemnly obey the responsibilities of a retainer, and if I violate the oath, I shall receive punishment from the willpower of the world."
Once Liu Jie's words turned silent, the purple Willpower Rune that was revolving around Liu Jie suddenly stopped. The rune appeared with a layer of mysterious chain, and it was locking up Liu Jie's Willpower Rune tightly on this end. On the other end of the chain was Lin Yuan's spiritual energy.
Liu Jie could feel himself and Liu Jie forming a superior and subordinate relationship.
This was a rune oath, and only people who comprehended Willpower Runes could take the oath. Violating it would cause the world's willpower to form a barrier, disallowing them to feel spirit qi again.
