If Tang Lei had not sacrificed - he had not fallen in that mission, the smiling trainer captain would still show up at the kennel on time every day, use his old key to open the Sirius cage door, and one person and one dog would run across the track in the early morning sunshine in Beijing.
If Sirius hadn't picked up the bomb - it hadn't made that heartbreaking choice at that moment, it would still be alive, still accurately locking the scent in every mission, and still swooping out when Tang Lei shouted "Sirius, search", its tail flying high, like a flag that never falls.
If Cherry had not been sacrificed - the Labrador who always rushed to the front would still rub Li Shuhan's palm with his wet nose, still be the first to lock the target in every explosive search mission, and then look back at her, waiting for the "good dog".
When all the "ifs" come true, every morning at the police dog base is complete.
Qi An came at this time. She is not a time traveler. She was born here and grew up here. She relied on her own ability to step up to the position of captain of the Interpol, and was wanted back from The Hague by the Beijing Public Security Bureau. The day she opened the base gate, Tang Lei was squatting at the door of the kennel whistling to feed the dogs, Li Shuhan was bending over to tie the leash for Cherry, and Ni Na walked out of the office building holding her notebook, and the entire runway was covered with sunlight. Sirius glanced towards the door and wagged his tail gently twice.
Everyone is still there.
Such a story begins with "no more loss".
