"A code?" Ye Luo furrowed his brows and looked at Chen Qianqian, "Qianqian, did your grandfather ever mention any numbers or anything like that to you?"
Chen Qianqian thought for a moment and shook her head, "Grandpa didn't tell me any numbers, but before he was taken away, he told me that it was almost my birthday, but unfortunately, he wouldn't be able to celebrate it with me."
"Your birthday?" Ye Luo's expression narrowed, asking, "Qianqian, when is your birthday?"
Chen Qianqian recited a series of numbers. He Fang glanced at Ye Luo, who nodded, and He Fang promptly entered a series of numbers into the safe. Suddenly, the safe was opened.
"You really got it right, kid," He Fang said with a smile, looking at Ye Luo before turning his attention to the safe. There were only two things inside the safe, a letter and a black key.
