"Cough, cough cough!"
A bout of coughing came from the cave as Sun Wukong crawled out. There was a faint trace of blood at the corner of his mouth, which he wiped away with his hand. Looking up at the Heavenly Demon Blood Shadow in the sky, his eyes blazed with astonishing combativeness.
"The complete manifestation of domain power is indeed formidable! Yet you are no Heavenly Dao Saint and this domain isn't truly yours. To think you can unleash its full power is pure fantasy!"
In this exchange of blows, Sun Wukong suffered minor injuries, but one of the advantages of the Chaotic Divine Body is an extraordinary self-recovery ability. Sun Wukong didn't even deliberately activate the Eight-Nine Profound Skill to heal; the minor wounds in his body healed on their own through the body's self-repair mechanisms.
If Sun Wukong's skills were limited to this, he would indeed have trouble facing the Jidu Demon Emperor, but he hadn't unleashed all his might yet!
