As the "ghost" of the group and the trump card of the audit department, Qiao Yin has three professional creeds: 1. When the geese pass by, they leave traces, and when the accounts are passed, they leave their voices. She has been here to find out all the false and bad accounts. 2. Absolutely invisible and elusive, resolve the battle before revealing your identity. 3. Stay away from the top boss, especially the legendary CEO who is so handsome that people and gods are angry but has a bad temper that can be smelled three miles away - Lu Siyan. Three years after joining the company, she has completed the first two perfectly and is a KPI legend in the department. Until she was sent to the audit group headquarters to face the big boss Lu Siyan. In order not to be exposed, Qiao Yin pretended to be an ordinary administrative girl. Her daily job was to copy documents, serve tea, and... Secretly install a micro bug in the president's office. Cross out, it is to observe the data port. She thought she was perfect, until one day when she was working overtime, Lu Siyan leaned against the door and looked at her leisurely. "Ms. Qiao," he shook a black gadget that looked like a beetle in his hand, "Is it time for the equipment in your audit department to be updated? The signal is not very good." Qiao Yin: "!!!" Her brain shut down in an instant, and she even thought about her suicide note. It's over, I'm going to pack up and get out tomorrow. However, Lu Siyan just chuckled and threw the "Beetle" back to her. "Don't be in a hurry to resign. There is a big fish in the group, and I can't catch it alone." He stretched out his hand towards her, with a bottomless smile in his eyes, "Formal introduction, I am your client. Do you want to cooperate, Auditor Qiao? I provide authority, and you are responsible for uncovering the mole.
