Open a Time Travel Training Class

"Didi, the system has released a new task now" "It has been detected that the host's professional title has reached Level 9 Lecturer. Please publish a paper with an impact factor of 7 or above within three days from the date of receiving the task. The paper must be closely related to time travel." "Reward for successful mission: promotion to associate professor. Punishment for failed mission: obliteration." "..." Looking at the tasks issued by the system, Tang Yuan felt like crying. Can you please stop being such a cheater! Why not just hold a time travel training class? Why do you need to rate it? !
