It took about ten minutes for the first firefighter to start crossing the river.
Just a thin climbing rope to traverse the entire river, with turbulent waters flowing beneath, it was truly frightening.
Yet, that firefighter was exceptionally calm, moving slowly but surely.
Initially, he moved slowly, but as he became more familiar, he sped up.
By the end, he was very fast, taking only one minute and forty seconds in total.
Once he successfully reached the other bank, he secured several climbing ropes and then gestured to the others:
"It's okay, come on over!" he yelled.
The next second, a group of four firefighters crossed the river simultaneously.
The firefighters might not have felt anything, but the people on this side of the road were genuinely shocked and frightened.
"Oh my god, isn't that amazing?"
"Nonsense, they're our invincible blue friends!"
Dozens to nearly a hundred people crossed in just about ten minutes.
