The person who chooses to ride the line is using their life to gain time for the other two.
As soon as Yu Qing's words fell, Yu Dongling immediately cried out, "No! No, Dad, there must be another way, we can't!"
Qin Hao was silent when he heard Yu Qing choose to ride the line, not expecting Yu Qing to agree so quickly.
Yu Qing looked at his daughter and then smiled, saying, "Dongling, I'm sorry. But it's too late to say these things now. Give Daddy a hug, okay?"
Yu Dongling's tears fell uncontrollably like beads from a broken string.
Qin Hao glanced at the timed explosive and silently estimated the time, then directly said, "We still have ten seconds to waste."
Yu Qing nodded slightly, then reached out and pulled Yu Dongling into his arms, burying his head on her shoulder.
