In "Pumice Stone Journey", bonfire activities are held every week, and players can throw in firewood at any time. After putting in firewood, players can get good rewards. The activity rewards are related to the abyss layer. If you reach 4000 contribution points and the campfire level reaches level five, you can get the highest reward for the current abyss layer. As for how much firewood to invest, there is no specific limit. Players can decide according to their own needs and resources.
