Moon Hua Sect had a rule that anyone who breaks through to the Transcendent Realm before the age of one hundred could automatically enter the Inner Sect and become an Inner Sect Disciple.
After all, longevity increases by as much as a hundred years after advancing to the Transcendent Realm, and one hundred years of age does not seem old any longer.
So this restriction is relatively lenient.
Zhao Zhi could have broken through much earlier, but he received many insights from Ling Xiao and realized there were many issues in his cultivation process; therefore, he deliberately suppressed his cultivation level and didn't break through.
During this time, he resolved these issues one by one, and his strength also improved significantly.
Although he is currently only a Transcendent Realm First Layer Martial Artist, once he advances, even Martial Artists of the Transcendent Realm Second Layer wouldn't dare to underestimate him.
