Jinling Cartilage

Camphor leaves in Nanjing fall all over the boulevards every year, just like the scar on Xue Pengfei's palm that always hurts on rainy days - it was scratched by broken glass and gouged out by the word "coward". He is what others call a "Nanjing soft-footed shrimp": when his girlfriend was snatched away, he would only squat on the ground to pick up scattered ginkgo specimens; when faced with public humiliation, he could only drink an entire glass of beer and run away; even the centrifuge in the laboratory had a temper than him. When his senior brother smashed a petri dish, he only dared to say "I will do it again." But no one knew that this boy, who couldn't even tighten the bottle cap, was staring blankly at the chitosan holder in the microscope. Those dense pores hid the bone nail design that he spent 300 nights working on, and also hid the words that he didn't dare to say: Lin Mengmeng's trembling shoulders when she turned around, the hair rope on Zhao Lei's wrist that should belong to him, and Teacher Gan Qi's words "Resilience is not cowardice." When the degradation rate of bone nails finally matched the human body's healing cycle, Xue Pengfei discovered that some of the hardness was engraved in the molecular structure - just like the old walls of Nanjing, which looked mottled but could withstand a hundred years of wind and rain. And the scars on his palms will eventually grow into armor stronger than bone nails.
