It seemed that the Vermillion Bird was in a deep slumber for hundreds of years for a good reason.
When Shen Yanxiao heard that, she was worried about the Vermillion Bird. Even though the two Phoenixes were slightly weaker than him, their mutual cooperation would far exceed the other bird. They advanced and retreated promptly to attack and to defend, and finally, to entangle the Vermilion Bird.
Xiu mentioned that the Vermilion Bird was injured and could not fight a prolonged battle. It would not take long before the Vermillion Bird fell behind in his attacks.
