Two streams of light quickly rushed out from the east of the Hell Extreme Domain. There happened to be a team of elites patrolling nearby. They were all armies gathered by the ten kings of the Netherworld under Emperor Yin's decree to temporarily seal off the surroundings of the Hell Extreme Domain.
The reason why Emperor Yin wanted to seal off the Hell Extreme Domain was to capture the Ghost Emperor of the North, Ullr.
Of course, Emperor Yin knew very well that it was impossible to capture the Ghost Emperor of the North, Ullr, alive with ordinary elites.
Emperor Yin only wanted the ordinary elites of the Netherworld to discover Ullr's whereabouts. As long as he discovered Ullr's whereabouts, Emperor Yin would be able to unleash the divine might of Emperor Yin's seal. He would instantly teleport to a place with a beacon and capture Ullr alive.
