The act of traveling back to the past was amazing.
Supreme powerhouses in the Myriad Worlds could send those with weaker cultivation bases back to the past, but it was impossible for even the strongest supreme powerhouse to send a Supreme God back to the past unless they possessed a precious treasure that contained the law of time like the Supreme Powerhouse Divinity that contained the law of time. However, supreme powerhouses were rarely willing to use such a precious treasure even if it was for the sake of their direct descendants, let alone others.
Duan Ling Tian did not understand the benefits of traveling back to the past; he thought that there were none. He was unaware that after experiencing this, his comprehension of the law of time would improve after he returned to the future.
