By the time Su Mucheng had ordered her food, waiting for the cafeteria's chef to specially cook and pack it, she returned to the office and saw that Li Jiangao had already arrived. Xu, probably being farther away, had not arrived yet.
At this moment, Li Jiangao was sitting next to Qiao Ze, listening to Qiao Ze's explanation.
"...The overall approach is like this, we first prove the validity of S(n) and P(x), ensuring these two tools can accurately describe and generate prime numbers. Then we prove that for any given even number e, we can use G(e) to find two prime numbers P(x) and P(y) whose sum equals e, and that completes the entire proof."
Su Mucheng, upon hearing Qiao Ze's words, suddenly thought of a joke she had seen online: how many steps does it take to put an elephant into a refrigerator?
She felt like laughing, but luckily she managed to hold it in.
Because when she pushed the door open, both men looked up at her.
"Su is back."
