Rowan did not hurry to attack or interfere with the destruction of his Ouroboros Serpents, without killing him, any casualties caused to his Serpents were useless, he would rather wait, as far as he was concerned every single moment that passed, he was getting stronger.
His Ouroboros Serpents had already finished healing inside the void in his hearts, and rearing up for round two, roaring their anger at their killers, they curled around the ring in his chest that was his World Engine, their blood burning.
Rowan kept them in check, they had already played their part for now. He had to be careful with the way he moved his pieces to achieve the best results possible.
Rowan had tasted the power of a Major God, and the abilities of Tenma, the so-called leader of the gods, must be at their very peak, as he was most likely not a Major God, but a High God.
