No Problem

Naturally, the people of the immortal sect wanted to convince them to enter the sect, but since words of kindness alone had failed to convince them to obey and worship the sect, they considered using strength to suppress Xuanyuan Mo Ze and Feng Jiu and prove to them that outside of sky there is the sky, outside of people there are people. Even though they were powerful, they were not as strong as the immortal sect's Venerables. 

The immortal sect's reputation would be harmed if they were not subdued, so they suppressed them at every turn and urged them to take the two Venerables' challenge.
