Li Banfeng obtained a Guide Token, purchased a train ticket, and prepared to go to Loess Bridge.
Shopkeeper Feng's elder brother, Feng Chongli, was still at Loess Bridge, waiting to conduct a major business deal. Throughout Li Banfeng's investigation of the railway tracks, Feng Chongli was the most critical clue.
He didn't tell Qiu Zhiheng the reason for his departure, only that he would return as soon as possible.
Only Shopkeeper Feng knew what Li Banfeng planned to do at Loess Bridge, and he accompanied him.
"My brother has a rule for doing business," Shopkeeper Feng explained. "You need to find a witness, and this witness must know both you and him. Not many people are aware of this rule, and he does not wish to tell others in advance. After negotiating business with him, many end up unhappy because they lack a witness."
Li Banfeng was puzzled. "Why must you find a witness? What if you don't?"
