Tribulation Sutra: Starting from the Five Dragon Gate Challenge

"Jie Jing", the world's rare object, the body is a black iron plate. Those who obtain the "Tribulation Sutra" use tribulations to open the way, rise up when encountering tribulations, advance through tribulations, break through small tribulations and break small realms, and gain supernatural powers through big tribulations. If they do not break through, they will die.
