Answer Before End of the Month

After Lu Zhou confirmed his mission, he exited the system space.

Lu Zhou's consciousness returned to his study room in his mansion. He wasn't in a hurry to start working. Instead, he went into the kitchen and made himself a cup of coffee. He then opened his computer and went on his MathOverflow account.

This was the world's largest and most professional mathematics forum, many well-known scholars such as Tao Zhexuan and Schultz had their own accounts and blogs, and Lu Zhou was no exception.

Even though Lu Zhou didn't update his blog as often as Professor Tao, he still liked to communicate with scholars from all over the world.

Lu Zhou knew that his thesis on arXiv should have been downloaded a lot of times by people around the world. He opened his MathOverflow email, and he was shocked by the number of email messages he received.
