"Did I come here just to be cannon fodder!" The young man, gnashing his teeth and running wildly, roared in Hongtian's magic force field. Behind him were sword arrays, gun arrays, sword arrays, halberd arrays, and colorful magic bullets, magic cannons, magic laser bombs, and magic laser bubbles.
"Eh? I don't know anything? Then what am I here for!" The young man wanted to lift the table in front of him and insert his pen into the eyes of the white-clothed super mage sister across the table.
"I'm not good at fighting spirit, I'm not good at magic, I'm not good at anything, I just run fast, am I here to make soy sauce, or am I here to be cannon fodder!!!"
"What? Assassin?"
"Stick your sister! Give me a stab and see!"
