Chen Lan opened his eyes once more, and the Celestial Emperor's head had just fallen before him.
He suddenly turned around and saw everyone, a smile spreading across his face instantly.
He succeeded. He successfully returned to the past, and seeing everyone alive and well was wonderful.
"Chen Lan, why do you look so pale?" At this moment, Yang Tian noticed Chen Lan's face was extremely pale and bloodless, expressing his concern.
"It's nothing." Chen Lan weakly replied, his voice barely audible.
He didn't expect the energy consumption to reverse time and return to the past was so significant. But that was normal since he needed to change the past where an Emperor Dao expert destroyed the Celestial Domain.
Returning to the past consumes energy based on what occurred during that time. If it was just having a meal without any significant events, it wouldn't consume much energy.
