When Guo Mordekaiser stared at the energy consumption curve jumping on the computer screen, the sky outside the office building was already dark. The time in the lower right corner of the screen jumped to 21:17. He paused with his fingertips on the mouse before clicking on the last page of the report - "Jinlan Building Energy Saving Renovation Project Third Quarter Supervision and Accounting Table". Under the heading, densely packed numbers were like ants lining up, and he had just used three formulas to cross-check the last line "Energy Saving Deviation Value of Air Conditioning System Frequency Conversion Renovation: 0.37%".
"Guo Gong, haven't you left yet?"
The office glass door was pushed open a crack, and Lin Xiaoman, an intern from the project department, poked his head in, holding an unopened loaf of bread in his hand. She went to the site to inspect the fresh air ducts during the day, and the cuffs of her white shirt were still stained with some dust-proof paint that had not been wiped clean. "Director Zhang asked me to send you the photo of the air duct insulation layer taken on site in the morning, and said that you need to check the loss of energy-saving materials tonight..."
Guo Mordekaiser sideways let her in and pushed the warm water on the corner of the table: "Eat something first. Just send the photo to my email. I have calculated the loss. It is 1.2% Less than the budget. The density of the insulation cotton is up to standard. I didn't waste last week watching the manufacturer change batches."
Lin Xiaoman said "Wow" and bit the bread and came over to look at his report: "Guo Gong, you are so amazing, aren't you? Last week, the manufacturer boss worked for a long time and said that he would have to pay more for changing batches. You took the test report and calculated the heat loss coefficient with him, but you asked him to change it at the original price. Director Zhang even praised you for being a 'supervisor with an abacus' - you know both construction and accounting. You are the only one in the company who has these two skills together."
