Five team members, five suicide notes, they will write them before each mission.
This time, Sun Yuchen wrote one more - for his son who might be born ten years later.
"If he can't come back, tell him that his father is a Tianhu, not a deserter."
Zhang Long drew a small flower in his suicide note: "For my daughter I have never met."
Su Ying's suicide note always has the same sentence: "Donate all my organs, and the password is the patient's birthday."
Xu Xiang's suicide note is blank, while Yang Sen's suicide note is a string of codes.
They know that after this mission, they will either become heroes or become ghosts that will never exist.
