After a fatal car accident, Lin Ye woke up in another world. What he faced was not the system nor his grandfather, but the desperate situation of being locked up in the mine. With a "borrowed" birthday poem, he averted the crisis. He made his first pot of gold through chemical experiments on purifying coarse salt. He originally wanted to use modern knowledge to improve his life in a low-key manner, but he didn't know that his every move had already fallen into the eyes of some big shots. That bag of snow-white fine salt caused unimaginable waves. Being led into the deep abyss of mystery and facing unpredictable big shots, Lin Ye realized that in this era, knowledge that is too advanced can either become a ladder or a noose. From a refugee to a craftsman, from a staff member to a hero... He just wanted to do some "side business" to settle down, but the torrent of fate pushed him towards the only path to supreme status. When the light of modern technology shines into the ancient court, is it a blessing or a curse? Is the world ready to welcome an "Engineer Emperor" with a unique painting style?
