The four giant beast shadows were already covered in scars and not at their full strength. Even though the disciples of the Beast Taming Sect were able to keep their battle formation intact and continuously supply True Yuan to help the giant beasts recover to their full strength, this still required time.
However, the Demon Cultivators took advantage of this time, unleashing their full power in an explosion that scattered the four giant beast shadows.
The Elders of the Beast Taming Sect who controlled the battle formation saw that many disciples were affected by the flute playing of the Elder from the Joyful Union Sect; they no longer forced the gathering of Spiritual Beasts. Instead, they disbanded the battle formation, preparing to charge.
They had already broken through the defensive array of Ten Thousand Crows Valley. Even without the help of the giant beast shadows, they could still win.
