In the third year after her spiritual energy was revived, Su Mian awakened the most useless ability - "Efficiency increased by 15%", which translated into human words means that it is a little faster to change PPT. She thought that her life was always to survive between Party A and her boss, until she used Party A's demand collection to collapse a tribulation fox spirit in the company bathroom at three o'clock in the morning. A window popped up on her computer: "The Aura Awakener file has been created. Number: null." At the same time, Gu Changyuan, an S-level awakener at the Tianshu Alliance headquarters, was staring at the signature that had not been solved for three years in the system log - Null. The entire alliance searched for a mysterious system maintainer for two and a half years, built the core scheduling system, predicted spiritual energy disasters in the three eastern provinces, and rewrote the intelligence encryption system. No one knew who Null was. All he knew was that every time Null took a shot, he was in the building he passed. On the day he first passed by Null, Null was holding an iced American style with a D-level rating and changing the 27th version of the plan at his workstation. He would not tell her that he had been looking for her for three years; nor would she know that every bug she fixed was preventing a disaster for him. The story of a migrant worker and the founder of Tianshu Alliance begins with a glass of iced Americano.
