太弱小了，没有力量

Meaning

"Xiānbèi" (rice cracker, sounds like Japanese "senpai") is the nickname for Arknights operator Eyjafjalla (sheep character). From Bilibili UP "一只大哈鱼"'s drunk video where he planned an "attack on Japan" over nuclear wastewater, mimicking her voice saying "Senpai!!!" It went viral for being hilarious.
