Speed of Life and Death

"Good morning, students. My name is Luo Shifeng, and I am a professor from the Extreme Branch Institute's School of Neurology. I will be giving a public lecture on reflexes. I hope that this year will bring you joy and improvement."

Luo Shifeng, who had an exquisite short beard, went straight to the point.

"Three points.

"First, our School of Neurology has a large public class. It has the most students. There are 1,500 students in the class today. There are many people, so I request for absolute silence. I do not want to hear any sounds from your communication devices or whispers. If you do, then please leave. Don't affect the rest of the students' studies. Watch the recording alone after class.

"Second, unless I ask you a question, if not you can ask me questions after class or during training. Otherwise, there's no way for us to go through this lesson.
