Chapter 390: Chapter390-A Fierce Battle!

Amid the chaotic battlefield, John remained casually at ease, hands clasped behind his back, strolling around the periphery. 

Despite being the one who had invited Adam and Blue Sea to join the fray for the Key of the Saint, he was paradoxically the most relaxed at the moment. 

Having unleashed Abyssal Prison, he had already taken complete control of the situation. 

The entire area of Hengfeng Valley was under his sway. 

The battle was merely a finishing touch.

Yet John didn't hinder the others from fighting. 

He could tell that Adam and Blue Sea needed a vigorous battle to prove their strength. 

And there were no more suitable opponents than Kingserp and Karthus at the moment. 

As guild leaders of the world's top ten guilds, while they had had their fair share of frictions, they had largely maintained restraint. 

Rarely did they have the opportunity for such a direct confrontation.
