A big joke was accidentally played on Shi Yu.
Shi Yu still refused to believe it until he saw Song Jiayao lying on the hospital bed with a bloodless face.
Many years passed, in that era of advanced technology, Shiyu purchased a time shuttle. But the condition for changing history is that human casualties must be conserved.
Shiyu has traveled through countless times and tried countless times. As long as he can exchange his own life for Song Jiayao's safety, it will be fine, as long as Song Jiayao survives.
How come the ending seems to be a foregone conclusion.
Song Jiayao was lying in Shiyu's arms.
"Don't cry, Ayu still has a long way to go. I want you to be safe and everything goes well."
Later, the machine told Shi Yu.
"If your current life is the result of someone else changing it, you can't make any adjustments to history."
Purpose: Youthful pure love, mutual redemption
