I Build Gundam in the Wilderness and Become an Immortal in the End of the World

In the apocalyptic world where technology is supreme, Lin Qiu's obsession with ancient books is regarded as an outlier. Once he was summoned to the wild world of spiritual energy, he became the "humanoid battle pet" of the tribal girl. Giant beasts are rampant here, totems are sacred, but even the wheels have to be rubbed by hand. So—— He equipped the Thunder War Eagle with vector thrusters, taught shamans to draw integrated circuit boards, used alchemy furnaces to extract high-energy fuel, and ignited the industrial revolution in the wild continent. When he brought with him a cultivation level far beyond the ordinary, and several cubic meters of "cross-border specialties". Facing the world-destroying beast that made armies around the world despair, he just calmly opened his tablet and called up data analysis: "Plan A: Inject reverse-phase psychic waves into its seventh energy node, causing local rule collapse. The success rate is 87%, and it will cost me 30% of my true energy." "Plan B: Use my natal flying sword to perform micro-resection to remove the diseased 'dao pattern core'. The success rate is 92%, but I need to rest for a week after the operation." The generals looked at the heaven-like energy maps and mathematical formulas on the screen, and their voices trembled: "Is this, is this scientific?" Lin Qiu pushed up his non-existent glasses: "They asked the same question when I was teaching the original artificial Star Destroyers next door." "Now, choose A or B? Just a reminder - my true energy, like your ammunition, is a strategic reserve for one shot and one less shot.
