The so-called purple heavenly tribulation actually came much less frequently than the normal heavenly tribulation of the Eternal Thunder Waterfall. On average, it would only strike two or three times a second. If you were in the Eternal Thunder Waterfall, it wouldn't be a problem for all the lightning to strike you more than a hundred times a second.
However, even so, the kings didn't dare to be negligent, because the purple lightning didn't seem to be exhausted at all. They were gradually paralyzed one after another by the purple lightning.
As for Han Fei, he secretly activated the Yin-Yang Millstone. In his heart, the Yin-Yang Millstone was activated. As long as this powerful purple lightning rushed into Han Fei's body, half of the power would be swallowed by the Yin-Yang Millstone and then transformed into the purest energy that flowed in Han Fei's body.
"Ahhh~"
