On the day Mobei City was destroyed, Shen Xingchen had just turned five.
She remembered that her father, Shen Pojun, said "Don't look back" when he stuffed himself into the tunnel, and then never came back. For thirteen years, she lived like a weed in the ruins of Mobei City by picking up rags and running errands for others. She was stubborn and sharp. Apart from her boxing skills, she only had a rusty short knife.
She thought her father was dead and her mother was dead too. She thought that her whole life would be like this - hanging out in a small border town day by day, occasionally going to the top of the city to look at the windy sand in the north, and scolding that irresponsible old thing.
Until that day, she picked up an old emblem on the black market.
