Using Devours The Earth To Draw In Heavenly Refinement

Zhen Hua was startled. Using seven elements in Heavenly Refinement basically meant you had already perfected the technique! In his many years of forging, it was extremely rare that he would be able to complete seven-element Heavenly Refinement. Moreover, his body would be severely injured every time he even attempted it. 

He opened his mouth, thinking to stop Tang Wulin, but he did not speak in the end. He believed that Tang Wulin would only learn his lesson by suffering the consequences. 

After all, they were at the Heavenly Ascension Platform, and Zhen Hua was there to protect Tang Wulin. If there were any unexpected troubles, he could at least keep him from being severely injured. 

How was the boy capable of drawing in so much origin energy to this place?
