"When he first started high school, a stranger told Lin Zheng that there was something of his in the bank's safety deposit box, and that the withdrawal password was a string of 32 digits. However, when Lin Zheng went to the bank, he was informed by the bank that the time was not right and that he couldn't withdraw his treasure. After that, Lin Zheng put the matter out of his mind." Po Jun rummaged through Lin Zhen's old books.
"According to Lin Zheng's memory, he must have logged the password in his mathematics book. After all, it's a string of 32 digits with no discernible pattern. With Lin Zheng's capabilities, it's impossible for him to remember them without aid." As he said this, Po Jun grabbed a corner of the book and pulled out the book he wanted.
