Hello!
This time, we will walk you through the event “Mountain Breaking, Rock Breaking”!
The event “Mountain Breaking, Rock Cutting” is for a limited time until May 31, 2026.
About the story
Bekas is the main character in this story.
As a result of his own style, he remains a C-class mercenary, so his pockets are always poor. On top of that, I’m a big eater, so I’m always hungry.
The story begins when a civil engineering project was being held at a restaurant in the village where he washed up.
The problem child Liselotte also appears, and the punchline is that she says she’ll use scissors with the idiot.
About limited time quest strategy
From the “Base” screen, enter the limited-time quest screen by selecting “Departure” – “Collaboration” and complete the following “Mountain Crushing, Rock Drilling”.
Stages 1-1 to 1-5 are left to the NPCs, so you can easily complete them.
1-6 “Shining Future” is difficult for some people because you have to fight with a team that you have formed.
If you can’t win, use your friends (select another player’s team from the “Select Friend” screen) and get help from strong players (which can be estimated by the amount of coins spent) to conquer the game.
Other than that, it is an event battle with fixed units, so the strategy is easy.
Construction shop
In this limited-time quest, you can obtain the exchange item “Special Alloy Ore”.
This is an item to be exchanged at the construction shop.
