Seven years ago, in an ancient southern temple, An Ci, a student at the Academy of Fine Arts, was sketching under the eaves and met Deng An, a carpenter who was repairing window lattice. When leaving, he stuffed a piece of Hetian jade scraps into her palm, said "warm and moist", and then disappeared into the sea of people. Seven years later, An Ci became a jade bookmark soft chamfer polisher, pursuing "an arc texture that won't hurt your hands." Deng An reappeared as a material quality inspector, only recognizing the industrial standard of "tough and wear-resistant". The two stood at opposite ends of the production line, separated by the demolition of an ancient temple, the concealment of hand injuries, and a misunderstanding spun by a third person. When An Ci discovered that Deng An secretly added soft light to the inside of her product, when Deng An's old injury on his right hand began to worsen, and when the eaves of the ancient temple were about to be bulldozed - they had to find the answer to the coexistence of soft light and toughness in the 0.1 Mm transition zone. This time, no one is allowed to leave first.
