Doomsday Cup

Is this a doomsday battle royale game? It's really funny, this is obviously a fair world! Eliminate the gap between people to the greatest extent, and rely on strength to capture everything. What I can get means what the enemy can take away from me. All this makes people like it, and the blood is boiling! ——————A militant man with abnormal thinking, relying on luck and strength, struggles in this world. (This book includes super fantasy content, psychological warfare, novelty content, no harem, single female protagonist, teamwork, and later includes cross-border battles. The characters are many and complex, and the plot is not confusing. I don't believe anyone can understand the cover)
