[g-] Gandalf is in [1] front of the [-e] electricity plant, unable to get in. He takes off his 合 glove and throws it into the air, whereupon it turns into a 鸟 bird! A 鸽 pigeon, to be precise, which flies around the electricity plant, looking for a way in so that it can carry a message to someone inside, it being a carrier 鸽 pigeon after all.
