We offered you a summer job, but you went and became a mercenary?

After the college entrance exam, Lin Ye, in order to save money to buy a computer, bound himself to the "Strongest Summer Job System." Looking at the 100-yuan-a-day waiter jobs in China, Lin Ye decisively opened the dark web: "Mercenary jobs in the Middle East, 10,000 dollars a day? You're the one!"
Two months later, the world lost a terrorist organization and gained a mercenary king codenamed "Shura".
As the new school year begins, Lin Ye returns to China carrying a snakeskin bag, ready to experience the wonderful university life. Unexpectedly, the school beauty is forced into marriage by an ancient martial arts family, and a scoundrel provokes him in the street?
Lin Ye sighed and silently pulled out the [Unlimited Power Gatling Gun] and [Grandmaster-level Fighting Technique] rewards from the system: "I'm just a soon-to-be college student after summer vacation, why are you forcing me?"
The National Security Bureau was shaken, and the highest-ranking official personally ordered: "Promote Lin Ye to Tsinghua or Peking University! He'll get full marks even if he doesn't attend classes! The university president will personally make his bed! As long as he doesn't throw a tantrum, we'll agree to any conditions!"
From then on, the Dragon Kingdom gained a privileged college student who didn't have to attend classes and received top-secret information every day, and the world's great powers ushered in their doom!
