The mere fact that she's a student would entice them even more because it would make her an easier target. Think about it Hawkeye. She's only a student, and she's up against several fully grown adults, former soldiers no less. Not only that, but the leader is a level 4, while Yue Yan's a level three, making him not only a great deal more experienced than her, but more powerful as well. She would not be able to win the battle alone. Hell, she may not even be able to adequately fight back out of simple fear.
Do it again, better this time. Always, always always remember that you will not always win. You must be realistic. A teenage student would only be able to defeat a battle hardened, fully grown ex soldier with great amounts of luck.
