The hydropower station is ruined. Three days of diesel left. Engineer Xiao Junzhi made a decision: break into Jinling to get the cold fusion prototype. There was only one bionic AI accompanying her - she named herself Xiao Suling, and her face looked very much like his deceased friend.

These three people will start from a dead city and walk two thousand kilometers westward along the canal.
