Delta Force: I'm the Ultimate All-Rounder Assault Player

Pei Qiong woke up one day to discover he had transmigrated to a world where Delta Force had descended. Here, maps like Zero Dam, Long Creek Valley, Brakkesh, Space City, and the Prison had all become treasure-hunting secret realms. The items inside had magical effects and were worth a fortune. Here, everyone had entered the age of treasure hunting... An invisible nobody in his class from the start? Pei Qiong chose to charge headlong into the map, earning both praise and admiration, as well as bounties and profits. Buried in debt from the start? Pei Qiong chose to enter Zero Dam and fight his way through to earn his starting capital! The secret realms were full of danger, and the NPCs were downright unhinged? The bosses were oppressively powerful, enough to make anyone despair? The other people entering the secret realms were all strong, too? No worries. I'm the greatest all-around attacker! What kid cries every day? What attacker loses every day?!
