[No System, No Supernatural Abilities, Five Transmigrators, No Rebirth, Pure Apocalypse]
When a piece of chalk jolts him awake in the apocalypse, his hard drive becomes humanity's last weapons factory.
Lin Yi is the infamous "odd genius" of Linhe County Experimental High School.
He is snoring away in physics class when his physics teacher, Zheng Guodong, a former grade-eight fitter, throws a piece of chalk that never misses. But this time, as the chalk whistles through the air, the sound outside the window isn't the school bell. It's a shriek that tears civilization apart.
Zombies surge like a tide. Order collapses.
Linhe County, once famous for its precision bearings, becomes a graveyard of steel and flesh in an instant. The first thought that flashes through Lin Yi's mind isn't fear, but the treasure at home his parents dismissed as "a waste of time": the small CNC machining center that roars away, the humming 3D printer, and... the encrypted hard drive packed with forbidden blueprints…
