Transmigrating to The Wandering Earth: I Join the Nation to Help China Rise

[Portals through time and space + The Wandering Earth + Spirit Cage + The Three-Body Problem: Building the Strongest Huaxia] Good news: delivery driver Lin Chen found a portal! Bad news: on the other side lies an underground city in the year 2075, during the apocalypse of The Wandering Earth. Extreme cold, scarcity, and danger at every turn. The game starts on hell difficulty! With nowhere else to turn, he immediately handed the portal, otherworldly technology, and top talent over to the country! The country stepped in, bringing the strength of the entire nation to reverse-engineer the apocalypse technology. From then on, Huaxia overtook the world on the bends, and its technology took off! While other countries were still struggling with energy bottlenecks, Huaxia had already achieved energy independence with fusion technology from The Wandering Earth! While the West was bogged down in internal strife over chip technology, Huaxia’s photonic chip technology had already monopolized the global market! Just when everyone thought this was the peak, Lin Chen quietly opened a second door. Beyond it lay Spirit Cage’s crimson wasteland, overrun by Devourers, with humanity on the brink of extinction. He brought Huaxia the Guiyuan cultivation system and life-source technology, and life-extending drugs became part of the national health insurance program. Then the third door opened. The Trisolarans’ sophons were locking down human science, the ETO had infiltrated the upper echelons of governments around the world, and the Trisolaran fleet would reach the battlefield in four hundred years. Lin Chen turned the sophons against their masters and replaced the ETO’s core leadership, turning the underground network the Trisolarans had spent twenty years building on Earth into Huaxia’s puppets. From underground cities in the apocalypse to interstellar fleets, from fusion energy to higher-dimensional technology: when the Trisolaran fleet reached the Solar System, Huaxia’s eleven-dimensional collider and super-strong material armor were waiting for them. The Trisolarans thought they were invading a planet full of bugs.
