Tang Shaoyang explained about the cultivators, mostly something he read from Grandmaster Xu's notes or whispers from Ouyang Biya. He knew he was not good with words, so Ouyang Biya helped him to explain about cultivation and cultivation along with the potentials.
The thing he saw from the cultivation was that it would not make them less reliant on a skill. Most of the skills had a cooldown, and cultivation didn't have that cooldown. As long as you had an internal energy to power it up, then you could use the technique.
Of course, he did not forget to explain the responsibility that came with the technique. If they accepted this opportunity, they would be responsible for rebuilding the Thousand Vows Pavilion. He had learned a little bit of the Thousand Vows Pavilion from Ouyang Biya, how the Thousand Vows Pavilion ran differently from the other sects in the Sacred Realm.
