I Was Laid Off, but My Wife Is the Trump Card of the Spiritual Administration Bureau

Three years ago, Lin Xian, the invincible demon in the fairy world, failed to survive the tribulation and was reborn into the mortal world. He became a laid-off programmer for a large factory and had a wife, Su Qinghan, who was as beautiful as a flower but worked overtime every day. He originally wanted to live in peace and retire, but he unexpectedly discovered that his wife was actually an S-class ace special agent of the Bureau of Spiritual Administration, and she was out killing demons all day long. In order to protect this cute and arrogant little fool, Lin Xian silently downloaded the Cultivation Darknet APP "Didi Fighting Demons" and resumed his old career as a "mysterious boss". During the day, he is a good, full-time husband who buys groceries and cooks. At night, he is a dark web legend who kills the demon king in seconds. He thought he was perfectly hidden, but little did he know that his wife was also wondering why the back of the salty fish husband at home was so similar to the mysterious boss...
