Where does this confidence come from?

The enemies that had raided the Chu Family were all taken care of, and the captured disciples set free. Those that were injured were moved to the infirmary of the clan so that they could receive treatment.

After they were set free, the disciples of the Chu Family angrily glared at the attackers that Venerable White had subdued. Some of the short-tempered disciples couldn't help but charge forward and use their fists to vent the anger and hate in their heart. The Chu Family wasn't a buddhist sect, and they weren't the type to repay ingratitude with kindness.

In the meantime, the new leader of the Chu Family, Chu Wenyan, and two elders arrived next to Song Shuhang and thanked him and Venerable White for saving the Chu Family.

Afterward...

Song Shuhang asked, "Right, family leader, is Miss Chu Chunying safe? After Fellow Daoist Soft Feather discovered what had happened to the Chu Family, she was very worried about her safety."
