The reason why Zhao Hai and Hu Yulong talked about Hu Yuan was that he was in closed-door training, and he had been in closed-door training for more than a year. Hu Yuan's strength was already very strong, and later on, he learned how to compress his energy, which made his strength even more powerful. However, because he was already old, it was impossible for him to go further. In other words, it was impossible for Hu Yuan to ascend again.
However, the situation here in the secret realm was a bit special. The energy here in the secret realm was very active. Hu Yuan was like Xia Yu. The energy in his body that was originally lifeless became active once it absorbed the energy here in the secret realm, which surprised Hu Yuan.
After that, Hu Yuan began to research on how to use his mental power. After cultivating his mental power, Hu Yuan suddenly felt something and went into seclusion. This seclusion lasted for more than a year. To be honest, this was really shocking.
