I Awakened Thunder, and the Female Ghost Sucked My Yang Energy and Got Zapped

[Rumble-Rumble Fruit + Wildly Satisfying + Ruthless + Supernatural Powers + The Paranormal] The paranormal returns, and demons and monsters run rampant. Lu Chen transmigrated eighteen years ago. Now working part-time as a food delivery driver, he gets pinned against a wall by a stunning female ghost in the middle of the night. The ghost opens her cavernous mouth, ready to drain him of his life force. At the brink of life and death, the Rumble-Rumble Fruit awakens! The Merit System activates! “Bzzzt, Boom!” A wild bolt of lightning leaves the female ghost tingling all over before killing her on the spot! At the same time, Lu Chen discovers that this System's rules are pretty interesting. Exorcise evil spirits? Merit points! Save someone's life? Merit points! Even striking down a school bully with a bolt of heavenly lightning after seeing an injustice can earn merit! As long as he has enough merit, he can not only upgrade his supernatural abilities, but also max out his martial arts proficiency! With a wave of his sleeve, Lu Chen maxes out his Observation Haki, gaining full-map vision and seeing through everything. No flashy tricks can fool him! Others spend half their lives studying the 《Two Demon-Slaying Forms》. Lu Chen spends a few hundred merit points to analyze and complete them, turning them into the 《Six Powers》! And that's not all. As long as he has enough merit points, even fake martial arts manuals from roadside stalls can be analyzed into genuine techniques! In this world fraught with danger, while the geniuses are still sweating through their arduous training, lightning flickers at Lu Chen's fingertips as he casually sets his skills to max level. “Cultivation? Isn't that what mortals do?” “I'm different! One step, one point! Steady as can be!” Years later, disaster strikes. Billions of evil spirits ravage the human world, and humanity is plunged into despair. Lu Chen arrives astride billions of thunder dragons, incarnate as the Heavenly Worthy of Universal Transformation of the Thunderclap of the Ninth Heaven. His dazzling divine might blankets the heavens! Countless Ghost Kings kneel on the ground, trembling. “That man is here!” The man standing amid a boundless sea of lightning, as if descended from the heavens, says calmly, “Come at me all at once!”
