At the thought of this, the Spirit Monarch no longer hesitated. He made a prompt decision and swayed his body once to retreat into the distance. The glint in his eyes suddenly turned dark blue.
Gu Yuena had been observing his changes all this time while simultaneously monitoring the battle between Tang Wulin and the Demon Empress. She was ready to provide reinforcements at any moment.
The sudden change of the Spirit Monarch's aura startled her. She hastily shifted her attention back to the Spirit Monarch.
The Spirit Monarch's body swelled up rapidly. He instantly turned into an abyssal Spirit Dragon fifteen meters in length.
It was only fifteen meters. Compared to the other abyssal Spirit Dragons, his size was way smaller.
In comparison, the three great Spirit Dragon Kings were each over a hundred meters.
Upon closer inspection, one would discover the differences.
