The Undead Pharaoh was dead, and the energy influx nearly killed Michael as it reached him.
Michael was fortunate that Archangel's Grace and True Extraction were still active. He used Extraction to drain bits of the energy influx and Insert to insert it into Archangel's Grace before using the Heavenly Realm Soul Technique to recuperate faster from his injuries.
It didn't take long to heal Michael to the peak, but he wasn't in perfect condition even after the effect of Archangel's Grace deteriorated.
His vision was still hazy, and he stumbled around the throne hall with unsteady steps. Nonetheless, Michael was alive and not on the verge of death anymore. With enough time, he would be fine. That was all that mattered.
"What are we going to do now? The Curse is dead," Michael asked, only to see a large serpent and a Wolf Head lean over the Undead Pharaoh's body.
