Brother-in-Law, Am I Better Than My Sister?

Years after nuclear wastewater was discharged into the sea, living creatures mutated. Ferocious beasts rose to the top of the food chain, and humans became their prey. Modern weapons were useless against the beasts. The only ones who could save humanity were martial artists. Chen Xuan had been born into this world eighteen years ago, but he had no golden finger or spiritual meridians, and couldn’t become a martial artist. He planned to lie flat and live off someone else, but his school beauty fiancée looked down on him. Then, just before the college entrance exams, his golden finger finally arrived. Chen Xuan awakened the Primordial Chaos Divine Physique and roused a dormant god-level spiritual meridian. When the Prodigy Rankings appeared, Chen Xuan rose to prominence, becoming an unparalleled genius and gaining a vast trove of resources. He decided to secretly support his school beauty fiancée’s younger sister. Training together rapidly raised both their cultivation levels, and the younger sister soon got a taste for it. She clung to Chen Xuan every day: “Brother-in-law, I want to cultivate dual cultivation with you.”
