In the near future, the most popular thing in the world will not be war or finance, but a super professional league called "Peak Battlefield" that combines e-sports, physical fitness, and real-life confrontation. Players must not only play games, but also run maps, decipher, and team games. It is highly enjoyable to watch. The protagonist was a retired agent who died accidentally while tracking down a multinational match-fixing syndicate. He was reborn three years ago and was bound to an "undercover championship system" with a less serious style. The system requires him to sneak into the league as a professional player, and while fighting for the championship, he can dig out the mastermind behind the game, laundering money and betting. Otherwise, the system will continue to deduct his "operational life" and make him more and more handicapped on the field. The protagonist obviously wants to handle the case in a low-key manner, but because of his heavy agent habits and too many saucy tricks, the league turns into a spy comedy scene.
