Frankly speaking, if the group had gone across the bridge one-by-one, this might not have happened! Unfortunately, no one wanted to fall behind and they were afraid that someone else would get to the inheritance first! Hence, they did not want to concede even one step!
As for flying through the air...
That was impossible!
Perhaps the Master of the ruins had wanted to prevent cultivators from flying through the air so he had placed water caltrops on the single plank bridge as well. If anyone tries to fly, they would end up badly bruised by the spikes from the water caltrops!
Hence, the crowd had no choice but to slowly cross this single plank bridge!
Gu Ruoyun had dared to step onto it because she was certain that she would be able to escape from the dragons.
"Argh!"
Just then, an arm reached out from the side and someone, who had been caught off guard, fell off the bridge.
