Although the plan to ambush the Demon God was agreed upon in the Nine Heavens and Ten Lands, due to the presence of a considerable number of opponents and neutrals, not all cultivators from the Immortal Sects participated in the battle.
Indeed, too many powerful beings acting together might not produce a positive effect; it could instead lead to chaos on the battlefield.
The first formation to engage the enemy was composed of the most resolute factions from the God-killing Sect, namely Tianshu Pavilion, Heavenly King Sect, Shu Mountain Sect, and Venerable Wanfa. They used the mightiest Divine Artifacts and struck with the fiercest blows!
Behind them, some from the Neutral Sects observed the battle situation, ready to act if needed. However, if the vanguard proved sufficient, they would not risk engaging.
