The monumental explosion occurred at noon, but the negotiation envoy did not appear outside Maple Fort until dusk.
Because before that, the Iron Peak County Military was busy retrieving people from the river.
To ensure that the culvert could be collapsed with a single blast, Mason ordered the "amount that guarantees destruction" to be loaded into waterproof coffins.
Yet, no one expected the underwater blasting to be so terrifyingly powerful. The sound of an explosion above ground was loud, but underwater, it could literally "turn the rivers upside down."
With a single coffin of explosives, not only the culvert but also every ship moored on the river surface was instantly overturned.
Fortunately, Mason, always cautious, had ordered the evacuation of unnecessary personnel from the site before the official detonation.
However, when the explosion occurred, the sailors on the ships and the engineers operating the winch were all thrown into the river.
