"Young fellow, are you really going to teach them the art of forging? Aren't you afraid of changing the history of the giant spirit race?" Ji Lutian, standing beside Zhou Shu, whispered. "I've been thinking recently. If history changes, will the two of us disappear?"
"I don't know," Zhou Shu said. Even though he had the Heavenly Emperor Jade Book and grasped a portion of the laws of time, he had no answer to this question.
His mastery of the Heavenly Emperor Jade Book could only accelerate time and not reverse it.
It was much more difficult to reverse time than to accelerate it.
Zhou Shu estimated that even if his strength increased by ten times, he might not be able to reverse time.
As for letting people go against the flow of time and travel back to ten thousand years ago, he didn't even dare to think about this kind of strength. He felt that it was almost impossible to do.
