I Will Retire in the Magical World by Cultivating Immortality

I was a loose immortal in this immortal world and lived happily for thousands of years, but I finally died in the ninth heavenly tribulation. When he opened his eyes again, he became a baby from a farmer's family in another world. Test result: Born without magic power, body wasted due to cultivation. The parents were worried and the villagers shook their heads and sighed. I'm quite satisfied - I can finally live a peaceful life. So, I started to seriously enjoy my retirement life. When I was five years old, monsters attacked the village, and I picked up a branch. Later, the whole kingdom began to spread rumors that a "born swordsman" appeared on the border. When he was seven years old, the master mage came to test his talent. He looked at the crystal ball that showed no reaction, with disdain on his face. He doesn't know that I just used an improved breathing method last night to trigger a hundred-mile elemental tide. Entering school at the age of ten, I was the only "non-magic" student at Knight Academy. When I graduated, my name was engraved on the honor list of all departments. I just want to plant fields, raise flowers, and study how crude magic is in this world. But there are always people who don't believe in evil. Until that day, the natural disaster of the undead will press upon the realm, the Holy Domain mages will be at a loss, and the kingdom will collapse. I stood up from the field ridge and patted the dirt on my hands. "It's so noisy... Are you going to let people retire?"
