Who knows how Song Shuhang's pseudo-immortal body in the cultivation chat group came about?

Song Shuhang was the main character in the cultivation chat group, and he had a pseudo-immortal body. As far as I know, the body of a pseudo-immortal is a special constitution that allows one to be immortal and possess powerful self-cultivation abilities. Song Shuhang had obtained this physique through long periods of cultivation and accumulation, and had used a special method to transform his body into a pseudo-immortal body. It should be noted that the pseudo-immortal body is not eternal. It will gradually disappear as his body ages. Therefore, Song Shuhang needed to constantly cultivate and maintain the health of his body in order to maintain the long-term existence of his pseudo-immortal body.
