Seeing Batman go left, Matt, who had been ready for action, charged at the other group of ninjas on the right side of the hospital without hesitation.
Although Batman didn't give any orders, Matt very consciously took it on himself to act as backup.
That was because Batman had never been defeated.
A strange whistling sound rang out. It wasn't ear-piercing, but was drawn out and deep, like the sound of a xun.
Alarmed, the eight ninjas on the left scattered and looked into the sky.
Thanks to their special training and nocturnal habits, they were able to see the black shadow approaching rapidly from the sky.
The enormous cape unfurled to form distinct bat wings. The blood-red lenses on the face flashed, as if scanning for prey, and there was a strange whistling sound.
"Batman!" a ninja cried out.
"Shut up and kill him!" the lead ninja immediately ordered in a low voice.
