I'm Poisonous and I Can't Fight

The Eastern Continent has been in turmoil for hundreds of years, and finally the world is divided into nine parts. Each state takes care of itself and proclaims itself emperor, commonly known as the Nine Emperors. In Nanhai, Yuezhou, there is a small town that is not part of Kyushu. It is called Taoyuan. It is said that descendants from all states come here to study. After graduation, all students from Taoyuan become the best in all walks of life on the mainland. In Taoyuan, there is a village called Taoyuan Village. No outsiders are allowed to set foot there. If someone invades, the whole country will be notified and all states will attack it. One day, an outsider came to Taoyuan and left a baby behind in the village. The baby's body was covered with black lines, but the strong people in Taoyuan could not keep the baby. The villagers looked at the baby, moved with compassion, and left the baby behind.
