Surprise.

Luna agreed to Yang Dao's request, even though she understood little. After arranging for food delivery, she left. Yang Dao called Professor Dew out for the operation room, as he called it, and had her eat. The Professor was very reluctant to stand up from her chair. She was dedicated to her work and understood that eating for energy is also necessary. 

She asked Yang Dao to put the meal on the table and she would eat it after washing up. Yang Dao had no qualms about it and served the food. Then, out of curiosity, he walked inside the room, where the computer was placed. He saw a coding screen being displayed on the monitor. This system had no operating system, so they designed one from scratch to fulfill their needs. He sat down in the chair, skimmed through the codes. Then he slowly started writing a code.
