Can Heavenly Lightning Have Any Evil Plans?

Du Shenglan, the most talented genius in the cultivation world, condensed sword energy at three, resonated with the Martial Monument at five, and went alone to the forbidden area at ten. However, the world's evaluation of him was just one sentence —What a pity.It's a pity the Du family already has a unicorn, and it's a pity the Du family wants to destroy Du Shenglan.Du Shenglan's father: "No matter how extraordinary you are, you cannot contend with the family."A like-minded friend: "I didn't mean to betray you. Helping you means offending two major cultivation families."A former master: "To destroy the Du family, unless you become the Heavenly Dao, but the Great Dao is just. If you become the Heavenly Dao, you cannot take revenge out of personal vendettas."In the land of the Nine Rivers, no one has ascended for three hundred years, and it is rumored that the Heavenly Dao is lacking. Reaching the tribulation period is the extreme for a cultivator.Therefore, the four great families remain unshakable, controlling the elements.Du Shenglan: ...Interesting.The four great families joined forces to hunt Du Shenglan, intending to force him to ascend and complete the Heavenly Dao.On that day, under the watchful eyes of all, Du Shenglan finally crossed the tribulation and transformed into... heavenly lightning."The Heavenly Dao can't help me eliminate evils, so I become the Nine Heavens Lightning Tribulation myself! When I'm happy, I'll strike one; when I'm sad, I'll strike two; when I'm heartbroken, I'll strike three...""Every ten days is a cycle, the first five days I'll strike the Du family, the last four days I'll randomly select a 'lucky person' among the scum, and on the tenth day, I rest.""No strikes on wedding days, mourning days, or at the end of the year..."Retaliatory comedic protagonist X sinister and ruthless devoted antagonistNote: The protagonist will later cultivate a human body again, but the original form remains as lightning tribulation.
