Even though the relationship between Batman and the police was not that tense in this universe, it was still unlikely that he would stay in Arkham's main control room and watch surveillance videos with Gordon for one or two hours.
Therefore, while he was downloading the videos, he fast-forwarded them to take a look at the videos that brother Jue had left behind.
Unsurprisingly, when the scene where Feng bujue gestured to the camera flashed past, Batman asked Gordon to slow down the video ... And finally, the camera stopped on brother Jue's smile.
"What does he mean by this?" Gordon looked at the screen and read,"does that gesture mean a bird ... Or an Eagle? What is he trying to imply?"
"That's ... Bat ..." Batman replied in a deep voice as he unplugged his device from the computer interface (you can think that he had a bat USB). It seemed that the download was completed."He did this to the camera, which means he wants to invite me to join the game."
