We Are in the Dungeon and Start with a Desert Eagle.

After the protagonist traveled to a world where he was looking for an encounter in a dungeon, he made a mistake. Awakened the arsenal system. The starting novice gift pack is a Sand Eagle. After that, it was taken out from the arsenal. Barrett M82A1, M249, M4A1, AA12. This kind of weapon should not exist in this world at all. Dungeon boss? Barrett dropped in one shot. A seventh-level adventurer? Ten grenades can't kill you. If that still doesn't work, then get a tactical nuclear missile. Dongfeng Express must achieve its mission.
