"Delayed Teleportation"

This is Chapter 1950, before chapter titled "The Loch Ness' Second Attack" 

If the team was to be hit by another attack from this unknown giant, they might all die right away. 

What to do?! 

When will teleportation start? How come it was taking so much time?!

The sonic guy also panicked and couldn't help but check the duration of his active ability once more. 

"I don't know! It should only take a few seconds, but there is a sudden space fluctuation and now, there is a delay!" 

The sonic guy didn't know why their group teleportation was delayed again for a few more seconds because there was an obvious space fluctuation yet there should be nothing causing the space fluctuation. 

Or maybe...the monster that attacked them before was the reason why they could not teleport right away?
