According to the True Martial Saint Lord's plan, breaking through the thirty-fourth layer of heaven in this universe was something he intended for Lin Yun to do, because doing so would enable Lin Yun to rapidly and significantly enhance his strength.
If that were the case, even if the spatial node connecting this universe with the Netherworld had greater dangers, Lin Yun would be capable enough to confront them.
In other words, if Lin Yun couldn't handle it, then he couldn't think of anyone else who could.
After all, Lin Yun's current achievements were comparable to those of Grand Master Taoist Ancestor Er Lee from thousands of years ago. He estimated that even if the reincarnated being of Er Lee's friend awakened, it might not be comparable to Lin Yun's current accomplishments.
