Back when Shi Feng was at the Seven-star Martial Spirit Realm, the Nine Nether Four Extremes Seal he cast could kill a Three-star Martial King Powerhouse. But upon reaching the Martial King Realm, every single star was a vast difference, and now, even if he was at the Three-star Martial King Realm, casting the Nine Nether Four Extremes Seal capable of killing a Four-star Martial Sovereign would almost completely deplete the energy in his body.
And to deploy the Nine Nether Soul-shocking Seal, a soul attack on a Four-star Martial Sovereign, the drain on Soul Power would be immense. Moreover, if the opponent also practiced Spiritual and Martial Dual Cultivation and possessed a Soul Power that was above a two-star Martial King of the third stage or higher, the chances of victory would be slim.
