Naturally, looking at those needles Allen became quite surprised for a second because he did not think those monsters could attack like this. But then he realized most likely only the queen had this kind of attack because she also has some kind of bloodline compared to those male bees and those soldier bees.
He just only got surprised for a second but instantly reacted. He already moves away from that place and at the same time shoots a bullet toward that monster. Even though the speed of those needles were faster, they weren't that fast enough for Allen. He did not even need to use the bloodline power to get away from that place.
