The Game Invades the Earth

Four people drop a lot of items. One of them has a sword with a high frequency vibration, which makes it easier to cut off tough materials. The other two drop rings, one of which has a miniature transformation ring, which enables them to use two items at once. The captain tells them that they've found four corpses, including the younger brother of the president. The younger brother doesn't want to participate in raids, so the guild members couldn't help him. The president gave him a bunch of rare items, so he's got a good chance of winning a boss. He's also got three corpses that were caused by a wild boss, and one of the corpses was cut by an enemy's sharp weapon. He warns the other members of the guild to search for people nearby, because they'll pay a heavy price for their reckless actions. The skeleton warrior says that this dungeon isn't as good as he thought it would be. It's more difficult than expected, and the combat coordination is way worse than expected. He needs to level up quickly.
