Sword Energy Descends on the Land

Five hundred years ago, there was a war between humans and monsters. The humans suffered heavy casualties, but they also won the war. In the end, the demon tribe retreated several miles to Lingjiang and then became the property of the human race. In order to prevent the demon clan from invading again, the human race built twelve nine-story demon-slaying towers, with twelve tower guards and many tower auxiliaries. They complement each other and share responsibilities. The tower guardian is also a position passed down from generation to generation, so the next generation of the tower guardian is also called the successor, but the known time is all determined by the tower guardian. As time went by, there were villages around these demon-slaying towers, and most of them made a living by fishing. Because the Lingjiang River is so big and half of the river is covered in heavy fog, only a few people except the tower guardians and auxiliary tower people know where the demon tribe is on the other side. The protagonist, Han Lingyu, is the successor to the Demon-Slaying Tower of Darkness. After listening to the story told by Grandpa Miao, he decided to become a swordsman. At the age of ten, he knew everything, started practicing martial arts, and started his journey!
