A Giant Warship Drifts In from the Start, and the Nation Builds the Nantianmen by Hand

[System mission + national scientific research + hard sci-fi + saving the world from the apocalypse] "System, you're telling me to drift a hundred-thousand-ton warship around and draw a heart in the ocean?!" With the apocalypse fast approaching, Lin Mo, a recent graduate, was forcibly bound to an outrageous System. Fail a mission, and he would be executed on the spot. Complete one, and he would receive technology far ahead of its time. But this mission was simply ridiculous: board a ten-thousand-ton warship at the Beiming test site and personally execute an extreme full-rudder turn. Lin Mo looked at the wrench in his hand, then at the security barrier around the test site, and decisively chose another path: He would turn himself and the System in together! So the Tianshu Bureau took over in the middle of the night, the Beiming test site adjusted its navigation tests, and an experienced helmsman joined in personally. The hundred-thousand-ton warship really did carve a giant circle two kilometers in diameter into the sea! First-round reward: [Sky-and-Space Carrier-Class Room-Temperature Superconducting Electromagnetic Catapult System]. It was only then that Lin Mo learned the truth: in thirty-six months, a solar catastrophe would sweep the globe. The long-prepared "Nantianmen" was still missing a path into space. Now, that path had appeared. From then on, the System set the problems, Lin Mo submitted them, and a vast scientific and industrial network solved them. "Next time, submit the mission." "We'll figure out the rest." As the White Emperor tore through the sky and the Luan Bird stretched across low Earth orbit, humanity would no longer have to sit and wait for death.
