This is a story that takes place in a parallel world. On a blue star in a certain galaxy. Lu Fan is a senior student majoring in international trade at a university. Their graduation project this year was to open an online store, and he reluctantly chose to sell arms. So an online store called "Hao Xiang Lai - White Rabbit Weapon Shop" was opened for business. It was originally just a prank, but unexpectedly, I actually received an order from the buyer. And the value of the first order is 2 billion! Just when Lu Fan was at a loss, not knowing whether to report it to the country or quietly close the store, a clear voice sounded: "Hey! Congratulations, you have bound the invincible Ultraman Mustang biangbiang weapon system!" … At this point, Lu Fan started on the road to becoming a weapons tycoon in the universe!
