At the Liang Family Winery in Xiqiao Town, Liang's daughter discovers that the unknown microbe L-07 in the aged qu is diminishing as the starter degenerates. Her father, Lao Liang, refuses both testing and preservation. As a result, the brewery's liquor turns cloudy and sour, a veteran brewer leaves due to a back injury, and Boss Zhao arrives offering to buy out the formula. Armed with laboratory gene sequencing and liquid nitrogen cryopreservation of L-07, she returns home to test a new starter batch. Persuading Lao Liang to test-brew using half a tube of cultured bacterial solution alongside half a brick of old qu, the resulting batch runs crystal clear once more, winning a ten-jar deposit from a local restaurateur. Father and daughter agree to preserve the microbial strain, and Lao Liang continues brewing with the revived starter, keeping the family craft alive.
