Mu Yan was the daughter of the Demon Emperor, and Ye Chen possessed a Demon Body.
In essence, they both fought and trained using demonic qi.
Demon Corpses continuously spewed forth from the Buddha Cave, and Ye Chen had no idea how many Demon Corpses were suppressed within.
As the Demon Corpses emerged to counter the Buddhist monks and martial artists, Ye Chen joined the fray as well.
Ye Chen had obtained the Daoist Treasure Jade Lotus, owing a karmic debt to the Heavenly Buddha Temple; he needed to repay this favor.
Buddhism emphasizes the relationship between cause and effect.
Unable to intervene in the battle above the Void, Ye Chen still contributed what little he could on the ground.
Jie Kong had already joined the fight in the sky. Although he had been expelled, at his core, he was still one of the Heavenly Buddha Temple's own.
