The energy from a quasigod-ranked Demon Monarch was massive beyond comparison, especially when he had lived a very long life. The amount of life force in him far exceeded mankind.
Incomparably thick life force was immediately fused together with the strength of Golden Dragon King's breakthrough of the fourteenth layer of the seal. It transformed into a mighty torrent that lashed onto every portion of Tang Wulin's body while simultaneously lashing towards the fifteenth layer seal.
This was the most terrifying part.
In reality, the Golden Dragon King's essence was already contained in the Golden Dragon King's consciousness back then after the tenth seal. The consciousness was constantly plotting against Tang Wulin and would attempt to control his body at the slightest available chance.
