Rebirth in 1975, Building an Important Weapon for the Country

Jiang Yuan, a genius doctor in materials science, was reborn in a parallel world in 1975 and became a newly graduated engineering college student. In this era of scarce supplies and backward technology, the "future technology sign-in system" he carries with him has become his trump card to change the world. From improving steel formulas to chip design, from people's livelihood technology to national weapons, Jiang Yuan has single-handedly promoted the technological leap of the entire era. And it all started when he gave up the national scientific research institute and chose to work as a technician in a local machinery factory that was on the verge of bankruptcy.
