Just as they had planned, Kane was to teleport to the north wall immediately after Barakah used his absolute ability on the beast knight. Normally, he could directly teleport just by selecting his destination from his Hunter Association identity card but since an enemy had appeared near him, he had to step onto the teleportation platform before he could leave. This was a mechanism put in place by earth to keep people from easily escaping from their enemies when they were cornered.
The dragon flame spread on the floor when it crashed into Barakah's shield. The shield was okay and looked like it could take a few more seconds of the attack. Luckily for Kane, the fire breath was not aimed at him so he and the teleportation platform he was running to were relatively safe.
