I Hand Over the System, the National Team Conquers the Heavens, and I Lie Flat

【System-based + the rise of a great power + infinite flow + multiple female leads + Drawing Sword + Marvel + The Three-Body Problem + Resident Evil + the Myriad Worlds】 “Officer, I want to turn myself in. There's a System in my head that can transmigrate across the Myriad Worlds and buy things wholesale!” After transmigrating and awakening a food-delivery System, Liu Yi'an heads straight to the police station and hands over his golden finger to the state! The state: “As long as you can bring back advanced technology, we'll do more than provide room and board. A hundred female agents will line up to serve as your bodyguards!” 【Not only will he hand over the System, he'll also lead the national team to steamroll the Myriad Worlds!】 First mission, “Bright Tang Sword”: Li Feilong is still shouting for Battalion Commander Yi? Liu Yi'an directly calls in the Dongfeng express! Drone swarms blot out the sky, a combined-arms brigade crushes the enemy with overwhelming force, and Anping County is wiped off the map in an instant! Staring at the Gatling gun in his hands, Li Feilong is dumbfounded. “Th-this is the Jade Emperor's army, isn't it?” 【It's not just about changing the plot. It's also about a technological leap in the real world!】 Go shopping in Marvel: “Hand over the Iron Man suit blueprints!” The real-world Longguo equips its army with mecha! Raid Resident Evil: “The T-virus is too dangerous?” The state turns it into Super Soldier Serum, doubling the physical fitness of the entire military! Enter The Three-Body Problem as a Wallfacer: “The droplets are invincible? Watch me whip out a two-dimensional foil and hit the Trisolarans with a dimensionality strike!” While Eagleland is still congratulating itself over its aircraft carriers, Longguo's star destroyers have already reached beyond the atmosphere. Eagleland breaks down: “Please stop delivering takeout! We really can't keep up!”
