In the Ultraman Universe, I've Become the Underworld King, Ruling the Cosmos

Si Ye transmigrates to the Ultraman world and becomes the King of Hades from Super Beast Force, building a new world with his own hands.

His power is peerless. One strike of the Dark Xuanming Black Hole leaves Ultraman Legend, one of the Mysterious Four Ultras, with no chance of escape.

He commands the universe, with warriors of the Underworld everywhere. Belial forces the prophet Delacion to abandon Ultraman King, leaving him to die in battle. Tregear goes head-to-head with Father of Ultra, humiliating him and making him lose face in public...

Making Tartarus submit has become routine. Turning Hikari and Mebius to his side and dismantling the Land of Light right before everyone's eyes is what truly takes nerve.

Everything has only just begun.
