Chapter 737: Flying Rainbow Mountain

"How can this be possible?!" Duan Ling Tian was shocked to the point his eyes stared wide open, and the Origin Energy in his hands swiftly increased at the same time to increase to the limit in the blink of an eye.

But even then, the Exquisite Jadebox remained unmoving and was utterly impossible to open.

Along with strands of azure energy, violet energy, and earthen yellow energy roiled within the Origin Energy in Duan Ling Tian’s hand, he tried to open the jade box, yet it still didn’t move in the slightest.

"This…" Duan Ling Tian was shocked in his heart as the Origin Energy and Concept on his hands dispersed, and his face was covered with an expression of astonishment.

When had he seen such a bizarre jade box?

"No wonder the message left behind by Father said that… So it turns out that he knew for certain that I’m currently unable to open the Exquisite Jadebox!" At this moment, Duan Ling Tian had completely come to realize the truth.
