Can someone judge a person's strength just through their ranks? How...shallow.
"The outside world is cruel. The more weak you are, the more likely you will die. The magical beasts you will see outside will see your rank first before attacking.
They choose their prey wisely. Similarly, you will be distinguished in the outside world based on your rank.
Don't make friends. They may be close to you now, but the next day you might need to kill them or see them getting killed.
Don't think you are powerful just because you have gotten into Beijing University. I have seen geniuses fall and average magicians rise. That is how hard work matters.
You are going to spend the next 4 years of your life in the university, and maybe for further education, you will continue to be here, so don't behave recklessly.
I don't demand you all to remain single, but even if you are a couple maintain a line of decency.
