Demon Lord on Earth: I Really Just Want to Ascend

Others rely on spiritual energy to cultivate immortality, but I rely on electricity to cultivate immortality! 100,000 Kilowatts of instantaneous pulse power is required for foundation breakthrough? The park's power grid couldn't handle it and tripped? It doesn't matter, I developed the world's only all-solid-state lithium metal battery with a single energy density of 1850Wh/kg and full instantaneous discharge power, which perfectly solves the problem of power supply for immortals! By the way, let's engage in controlled nuclear fusion, which has been stuck around the world for decades! After all, in the future, the breakthrough of Jindan and Yuanying will only require more power. We can't always rely on controllable nuclear fusion and battery arrays, right? So—— I build a Dyson sphere directly in the solar system, swallow the energy of stars, and turn it into infinite spiritual power! Build a planet orbital gun and blast the asteroid with one shot! Build an interstellar super battleship and conquer all races in the starry sky! He even created two-way foil, water droplets, and physical law-level killer weapons! When the tribulation-era monsters, ancient gods and demons, and starry behemoths from the world of immortality arrive, they want to crush mortal technology. I smiled lightly. The water droplets attack and penetrate the body of the strong man in the tribulation period! A volley of railgun fire blasted the so-called supreme supernatural power to pieces!
