And Little Qi is the 'envoy' guided by the Heavenly Dao.
The birth of Little Qi originated from a dead dragon egg in the Heavenly Demon War on Broken Blade Mountain, resurrected by the power of the Heavenly Dao to become a Holy Spirit. The reason the Heavenly Dao descended Sweet Dew was because An Jing wielded the Heavenly Sword.
It can be said that the very existence of Little Qi is a 'reward' for An Jing's perfect performance in the Bitter Silence Seal battle at Broken Blade Mountain.
And now, as Little Qi instinctively activates its Divine Skill [Inverting Yin and Yang], and the transmitted Mixed Spirit Evil, An Jing can feel his Inner Array Realm [Primordial Heaven and Earth Born] rapidly operating.
At the same time, his Heavenly Mandate, stimulated by the Heaven and Earth Law contained within the Mixed Spirit Evil, begins to brighten.
