Taking Action (Part 2)

He would use his supreme power to protect Qin's divine soul from being destroyed, while helping him to complete the transformation into a divine being of the Heavenly Dao.

After becoming a divine being of the Heavenly Dao, Qin's karma would be severed.

Furthermore, with Chu Xuan's protection, the other party would not be able to detect that Qin was still alive, unless he showed up personally to check, which would not happen.

There was no reason to.

After all, no one below the chaos supreme realm could resist the power of the supreme laws of the chaos. 

Chu Xuan did not choose to meet force with force.

There was no need for that.

The other party had no enmity with him.

The reason why he had acted to protect Qin was not only because he was the one who had instigated him to kill Prison Dao Ancient God, but also because Qin possessed a large amount of the Heavenly Dao's fate energy.
