At night, Xiaoxiao wrote back to the mysterious person who sent the email asking who the other party was. The mysterious person replied that he was here to help her. At work the next day, Xiao Xiao looked at all his colleagues suspiciously, wondering which of them this person would be. The mysterious text message instructed Xiaoxiao to go to Sister Xue in the data room on the 29th floor to prepare a cup of coffee with sugar and milk, where Xiaoxiao met Lu Mang who was searching for information.
