He handed the note to Pei Zhiyao, which bore a string of numbers that looked like a password.
"Let me introduce myself, my name is Liu Jinbo."
"This is Zhang Huasheng's safe deposit box password; he said that even if he died, this password would still be used," Liu Jinbo said.
Pei Zhiyao and Wen Mian exchanged glances, both aware that this clue might be their only hope at the moment.
"We will seriously consider this clue and will give you an answer tomorrow," Pei Zhiyao said.
Liu Jinbo nodded, then stood up and left the coffee shop.
Pei Zhiyao and Wen Mian followed suit and exited the coffee shop.
"Do you think this clue is reliable?" Wen Mian asked.
Pei Zhiyao was silent for a moment before responding, "As it stands, this is our only clue, and he has no motive to deceive us."
Wen Mian nodded, knowing that Pei Zhiyao was right.
Now all they could do was hope that this clue was correct, or they might end up with nothing.
