Parasitic soul of Douluo continent

After three or five hundred years from the Tang Dynasty, the Wu soul is no longer awakened. Everyone can inherit the Wu soul of one of their parents as their own Wu soul, which has a very small probability of variation. Soul masters call this method "parasitism" once someone is born as a waste wood, someone wins at the starting line. It doesn't mean that if the person's parasitic martial spirit is not good, it's doomed to end his life. Therefore, they set up colleges, both specially built for noble parasitic and perfunctorily built for waste parasitic martial spirit. It's generally not good to graduate from waste parasitic Wuhun college, but there are also miracles.
