I’m Ne Zha, the Demon Child, and I Beat Up Yuanshi Tianzun from the Start

[Nezha + Ao Bing + System + Pure Power Fantasy + Investiture of the Gods + Journey to the West + Primordial World] "When the devil child Nezha binds himself to the Primordial World Sign-In System, he beats up sages and rewrites the Primordial World!" Lin Xiaozha, a 3D modeler who died suddenly after an all-nighter, transmigrated into the devil child Nezha in the world of Investiture of the Gods. From the start, Yuanshi Tianzun pinned him to the Immortal-Slaying Pillar at Jade Void Palace, and the white light from the sage's fingertip crushed his soul. "If I can't finish this job, I won't even be able to afford my mom's painkillers!" At the end of his rope, the Primordial World Sign-In System suddenly activated: [First Sign-In Reward: Saint-Slaying Spear, damaged version!] Lin Xiaozha grabbed the spear tip that could pierce a sage's skin and slapped Yuanshi Tianzun right in front of the Twelve Golden Immortals! Shock value +9.99 million! From then on, this modern soul rampaged through the world of Investiture of the Gods with a God-Slaying Spear that could devour a sage's blood, the Ancestral Dragon's Space-Rending Claw, and the Ancestral Phoenix's Nirvana Flame: Hurled into the Dragon-Han Primordial Tribulation, he stole the Ancestral Dragon's reverse scale and tore through time and space; Wandering into the Ancestral Phoenix's Nirvana Sea, he put up the Karmic Fire Red Lotus as collateral and swindled away a divine artifact; Reborn as a Devil Pill fetus, he devoured his twin brother and turned the tables on Yuanshi's puppet talisman! When the heavenly tribulation curse descended three years later, Nezha rode his Wind-Fire Wheels and tore open the sky screen: "You old bastard, you siphoned the nourishment from my mother's womb back then. Now it's time to pay up!" What kind of devil child is this? He's clearly the most rebellious battle god in the Primordial World!
