Tracking.

Shi Lang made his way to Jane's old home. Her mother was a staff member of the Federal Archives. She would be able to help him better than anyone else. He retraced his steps through his memory, and despite the fact that he had spent his entire life in this neighborhood, it felt as if he had stepped into some unknown locality. 

He looked at the streets and sighed, "To think life took off at the speed of light." 

After reminiscing for a bit he moved ahead and climbed the steps of a building. He knocked on the door and waited for a response but when he did not get any response, he smacked his forehead and said, "I forgot she might be working, how dumb of me." 

He was just about to turn around when a familiar voice sounded behind him, "Oh, mighty Lang also has moments when he acts dumb?" 

Shi Lang chuckled and turned around, he said, "Hahaha, Martha, my sweetest. How are you?"
