The toughness of his interstitial world was beyond his imagination. He found it unbelievable that his fist, which had almost exhausted all his strength, hadn't broken his interstitial world.
However, great ancestor Yu quickly launched a second punch, using all the power he could use! But it didn't work! His interstitial world didn't even crack!
"What should we do with this Suan ni?" The great Demon Dragon was a little dumbfounded. He felt that great ancestor Yu was weaker than he had imagined. That Xiao Ling could enter and leave this interstitial world as she pleased, but not only could this old man not do it, he couldn't even break it open.
Great ancestor Yu, who was being questioned, didn't look too good either. He was struggling in his heart. His true strength was naturally not just this, or he wouldn't have been chosen to be The Guardian after the Battle of the Gods investiture.
