Scientific Cultivation of Immortality

After Gu Huanyu died suddenly while working overtime, he took a mysterious ancient jade with him and traveled to the ancient world where the immortal civilization was at its peak. When everyone regarded him as useless and looked down upon him, Gu Huanyu quietly carved the micro-reactor into the mountain-protecting formation. When the immortal came to the sky and despised mortals, Gu Huanyu showed off the electromagnetic rail gun: "Sir, times have changed!" When the Demon Emperor coerced hundreds of millions of demon soldiers to tear the sky apart, Gu Huanyu silently launched a planet-level strategic deterrence agreement. "Immortal magic weapon?" Gu Huanyu smiled while sitting in the information command center, "I'm sorry, my major... Is the sea of stars!" Many years later, a motto spread in the world of cultivation: "You don't have to believe in ghosts and gods, but you must respect science."
