Is theology the end of learning? No, the end of immortality is quantum mechanics.
Chen Xian, a graduate from the Department of Physics, was forced to become a glorious courier in the city due to the severe employment situation. He originally thought that the biggest trouble in his life would be the delivery of food overtime and a bad review, until that rainy night, he picked up a courier box next to the trash can. There was no inflatable doll in the box, just a dirty little white fox. It has eyes of different colors that make all living beings tremble. Its left eye hides the deep space at absolute zero, and its right eye burns with the flames of a supernova explosion.
From that day on, Chen Xian's worldview collapsed. He discovered that the hot female neighbor next door could actually "phase shift" (the art of walking through walls); the man selling pancakes and fruit downstairs mastered "thermodynamic reverse entropy" (making fireballs with his bare hands); and the sword fairy's light that occasionally passed over the city was just someone who modified the local "gravity field constant".
Facing this world that was infiltrated into a sieve by high-dimensional particles, Chen Xian looked at the arrogant and picky little fox in his arms, who was no bigger than a palm but always wanted to rule the world, and sighed: "I just want to deliver a takeaway in peace. Can you immortal cultivators stop troubling Newton?"
This is the story of a scumbag from the physics department who takes an alien queen fox and uses scientific (physics) knowledge to conquer demons and eliminate demons in the city (this kind of statement is unscientific) and support justice (and make money by the way).
