The Seven Dragon Kings had finally arrived, which also invigorated Nian Bing. Like the situation below, both his magical and spiritual power were significantly weakened. Even with the help of Xi Lu and Oscar, they could only draw a tie against the three thirteenth rank experts in front of them. Nian Bing was naturally aware of the strength of the Seven Dragon Kings. Kajethesis had certainly reached the thirteenth rank, and the other six Dragon Kings were also at the twelfth rank. Coupled with the Dragon Clan's naturally powerful bodies, their selfless cooperation, and the enigmatic Dragon Language Magic, their combined strength would not be inferior to the ten god-men currently present. If the Dragon Kings were determined to break the seal, then only Ya Yue and his Undead Army below could possibly withstand them.
