If the crowd on the day of execution was considered massive, the situation at the city gates was so chaotic the throngs of people would easily cause a claustrophobic outcry.
It could not be helped. After experiencing the Water Ball flushing the city and swept by the "plague", the citizens were at their last straw and if there was going to be another unfortunate event, it would cause a complete meltdown in the city.
Therefore, when they saw the notice put out by the Church that the gates would be reopened, many cried tears of joy as they saw the light at the end of the tunnel. They gathered at the gates anticipating the opening of the gates according to the time stated in the notice. They could not bear another second to leave the capital.
Well, it was fortunate that the capital had four gates, to divide the traffic flow or else there would be deaths by stampede.
