After all, if Veluriyam Capital and Pillfire City were to go to war, Jiang Chen would feel no psychological burden in killing Emperor Yun Lan, the Celestial Emperors of the Heavenly Sound Temple and the Heavenly River Palace.
However, these individuals are now controlled by the Demon Lord of the Heavenly Demon, assuming a different identity; killing these people gives Jiang Chen a sense of sorrow akin to a rabbit mourning for a fox.
The Vermilion Bird Divine Beast seems to see through Jiang Chen's thoughts and persuades him, "Jiang Chen, there's no need for sorrow. Since ancient times, your human faction has never lacked such scum. The elites of the Ancient Era human faction never showed mercy to those traitors who defected to the demon tribe. Since they have betrayed the human race, killing them is not akin to murdering your own kin. Besides, if you don't kill them, once they escape, they will certainly bring calamity upon your human faction."
