Although Zhu Wuyang was confident that he could overcome the Heavenly Thunder Tribulation and even the Inner Demon Tribulation, he decided to start with the Five Elements Tribulation after some consideration.
Since there was a safer way, why would he choose those dangerous methods of advancement? After all, those dangerous methods of advancement would not bring Zhu Wuwan stronger strength or a stronger cultivation foundation.
Moreover, after passing through those dangerous tribulations, it was inevitable that he would have to pass through the Five Elements Tribulation. Therefore, why not follow the relatively safest method of passing the tribulation that had been summarized in the cultivation world for hundreds of thousands of years and slowly pass through the many tribulations?
Tribulation of Gengjin!
