Chen Yuan squatted beside the scrap pile at the edge of Rusty Iron Town, rummaging for something with an iron bar bent into a hook shape. His movements were slow and careful, like an old farmer looking for missing ears of wheat in the fields. Three days ago, he was still typing codes on the computer screen in his cramped rental house, working overtime until two in the morning, and even forgot to eat dinner. Then there was a violent dizziness, as if something had been thrown from a high place. When he opened his eyes again, he was already lying in a pile of junk that smelled of engine oil and metal rust.
