Having a soul on their head was the most important characteristic of the people in the soul world. Zhao Hai had seen that the people in the soul world had all kinds of soul worlds. Only the people in the variant human continent had no soul on their heads and were regarded as aliens. Moreover, they could only learn physical cultivation techniques and could not learn other cultivation techniques.
In the spiritual weapon world, the people here also had souls on their heads. However, the cultivation technique they cultivated was slightly different from the one in the soul world. The soul on their heads was not their main cultivation technique. They might have a sword on their heads, but they used a saber. Therefore, after coming to the spiritual weapon world, Zhao Hai rarely paid attention to the souls on their heads.
