Yin soul was not strong.
Even if they were at the True Self Tier, without martial arts techniques, they couldn't draw on heaven and earth's Regulations. They could be wounded by high-level energy. They had too many weaknesses.
However, there was probably no one else that could deal with it as easily as Ling Han.
"Going by that theory, this is Netherworld?" Lin Luo walked over. He had naturally heard Ling Han's words just now.
Ling Han nodded and said, "This is a connection point with the Netherworld. It was sealed by the Holy Emperor using a powerful technique, but after such a long time, this seal has loosened. Going by the looks of it, it won't be long before the seal loses its effects completely. At that time, a large number of Yin souls will penetrate deeply, and it will be inevitable that a great battle will break out."
