Delta Force: I Can Rewind Time Within the Rules

Wang Jiahao transmigrated to a parallel world where Delta Force had yet to appear. He thought he could use his memories from his previous life to make a name for himself in Delta Force and earn a fortune. But things didn't quite go the way he expected. Delta Force did appear, but to his surprise, everyone was pulled into the game and matched up, experiencing the thrill of real gunfire firsthand. Here, Haf Coin was everything. They had to earn Haf Coin to stay alive, because once their balance hit zero, they would die. But 10,000 Haf Coins only bought an extra hour of life. Everyone started with just 1,000,000 Haf Coins, while Wang Jiahao had a mere 240,000, a full two days less than everyone else. To survive, he'd have to work twice as hard as the others, or even several times harder. It wasn't just Haf Coin that was counting down their lives. The operators they encountered in the game were just as deadly. This wasn't a game. It was the real world. The operators followed their own rules for killing and had no regard for reason. Only the right items could protect people from their deadly rules. While everyone else was cautiously exploring this unknown world, Wang Jiahao was far ahead of them, thanks to his experience from his previous life.
