Rowan was getting increasingly pressed, as the gods he had slain returned, carried by portals of darkness created by Tenma to quickly bring them back to the field of battle.
The pressure on him grew from insane to impossible, and his single drop of golden blood hovering in the air began to shrink, if it was destroyed, all that power would rush into his Mental Space, and Rowan did not want such an event to ever occur.
Unlike both gods he had killed, Rowan was wary of allowing a Major God's power or higher to enter his Mental Space, because their Intent was more developed and powerful, they might be able to see what was inside his Mental Space, although Rowan did not think that was possible, he would rather not take that risk, not if he could help it.
The power being endured by the single cell increased until he knew that he had barely ten seconds to hold on.
