In the winter of 1970, mechanical engineer Shen Ming accidentally traveled through time and became a down-and-out educated youth in a forest farm in Northeast China. Facing the dilemma of lack of supplies and technological blockade, he dismantled shotguns and converted them into machine tools, smelted silver coins to make instruments, and launched a hard-core industrial revolution in the forest and snow fields.
From improving the gear set of the threshing machine to using rosin to break through the photoresist blockade; from purifying optical glass from forestry crystal mines to breaking down the international semiconductor monopoly with gallium arsenide wafers. Shen Ming used the mountains and forests as a laboratory, transformed an abandoned agricultural machinery station into a precision manufacturing workshop, used the Manchukuo mine data to counter KGB spies, and created the "Chinese Core" in the spy shadow of Harbin Port.
When the photolithography machine on the Western embargo list was born in the forest farm, when Moscow exchanged aviation aluminum for Northeastern rosin glue, and when Hong Kong merchants rushed to buy wafers and spent foreign exchange coupons - this time traveler with future memories was using nanoscale blades to carve a crack in the Iron Curtain of the 1970s leading to the sea of stars.
