Let's take it from the top and look over it again.
It's pretty much confirmed that the two shadows were of Fang Tianyu and Yu Fen.
What made them abandon their daughter to fend for herself, while they desperately entangled themselves with the bizarre?
The co-driver's exact words were that the train suddenly encountered a strange invasion.
Then Fang Tianyu, out of great benevolence, stepped forward and traded his life for a moment of peace.
But this consolation demanded a continuous "sacrifice" of subsequent passengers.
Still not right...
Why on earth would Yu Fen die with Fang Tianyu?
Or rather, what exactly happened that led them to forsake their daughter, who was only a few years old?
The strange phenomena, the Fang couple, Xiao Qi...
Unless?
Jiang Xiao opened his eyes.
That's it, there was another possibility!
The only thing that could make the elderly couple choose to give up their lives was Xiao Qi!
In other words.
