After the destruction of the Raging Flame Sect, the army from the Azure Sky Kingdom did not stand around and wait for too long as they knew that the Heavenly Sky Kingdom would soon find out about the fact that they had already entered their territory.
So, with this in mind, the Azure Sky Kingdom directly moved forward and launched an attack towards the central region of the Heavenly Sky Kingdom before they could prepare a proper defence. Taking control of the now former Raging Flame Sect in a bid to secure an easy path into the Heavenly Sky Kingdom.
All of this happened after Xuan Hao and Shu Yao had already returned back to the Flying Sword Sect to meet up with the other elders who went out to deal with the different branches of the Raging Flame Sect spread out across their territory inside the Heavenly Sky Kingdom.
