The Heart of the Divine Tree began to tremble violently, the runes on its surface flickering erratically, as if ready to extinguish at any moment. A powerful force of rejection emanated from the Heart of the Divine Tree, causing Gu Sheng's blood and energy to churn turbulently, and a trace of blood seeped from the corner of his mouth.
"Damn it!" Gu Sheng gritted his teeth, refusing to give up. He knew in his heart that if he couldn't refine the Heart of the Divine Tree, all his previous efforts would be in vain.
He grasped the Heart of the Divine Tree tightly with both hands, mobilizing all the Mystic Yellow Power in his body, and frantically assaulting the defenses of the Heart of the Divine Tree.
As time ticked by, Gu Sheng's complexion grew increasingly pale, his clothes soaked with sweat.
His body shook more and more severely, as if it might collapse at any moment.
