Delta Arrival: Start with a Private Secret Service

(The rating has just been opened, so it is a bit low. It will increase in the future!) Delta fan fiction+System+Pretending to be a pig and eating a tiger+Onslaught+Violent flow After time travel, the game invades reality! The "Operation Delta" I played has become a terrifying restricted area for all Blue Stars! Not only am I familiar with all the maps and strategies, but I have also activated the only private secret service system! Others start with a small pistol, but I start with a private arsenal! Lack of guns? I directly built a production line to make M7 and A Da unlimitedly! Shortage of people? I captured a Hafk team with my backhand, and they will be my pioneers tomorrow! From a single-handed lone wolf to a commander commanding thousands of troops. When Hafk's army pressed forward, the entire Blue Star technology was blocked and fell into deathly silence. Lin Yuan stood on top of his war fortress, with the torrent of steel behind him. "Now, it's time to switch between offense and defense!"
