Laura and the others couldn't help but be shocked when they saw this. It should be known that there was a layer of protective shield around the carriage. That layer of protective shield had quite a lot of defensive capabilities, and it could at least block a full-powered attack from a unity soul cultivator. However, this Iron Arrow had directly pierced through the protective shield and nailed into the glass with such great force. This was the most shocking thing for them.
As for the iron Arrow not piercing through the glass, that was very normal. The glass of the carriage was not ordinary glass. To be honest, the glass of the carriage was not glass at all, but a kind of crystal. The crystal was very hard, so the iron Arrow naturally could not break the crystal.
The person who was attacking them outside did not expect his arrow to be blocked by the carriage. He was stunned for a moment before he slowly walked out from the forest.
