"Our reflexes lesson is to train you in the speed of your reflexes.
"Under normal circumstances, a person's reaction speed could reach 100 milliseconds or even lower through extreme training. However, the difficulty was too great. Furthermore, the ability could not be used in general.
"In this Genetic Era, elixirs could greatly reduce the time it took to train our reflexes. The target of our reflexes lesson is 10 milliseconds. If your reflexes do not reach 10 milliseconds a year later, your personal rating would drop by a grade."
Xu Tui's eyes flickered. A year later, if an individual's reflexes were less than 10 milliseconds, their rating would drop by a grade. Out of all of the classes, this was the only one that the students would be demoted if the student did not meet the requirements.
The school must have made such a rule to emphasize the importance of a person's reflexes.
