I Clicked Excel

My name is Chen Mo, 35 years old, with a monthly salary of 2,800. When the system came and everyone was chasing the sky and the earth, turning stones into gold, I silently turned on "Excel Mastery". Later, the Demon Lord came to the city with an army of millions. I handed over a function-generated "Demon Army Logistics Supply Chain Vulnerability Analysis Report". The Demon Lord vomited blood on the spot, and the financial director defected overnight.
