**From cicada shells to slide rules, he used his skinny bones to build the concrete wall of life. **
Nine-year-old Chen Lifeng climbed a tree to pick up cicadas in exchange for sweat-soaked tuition fees. His father's silent palm burned "responsibility" into his bones and blood. During his four years in college, he was an isolated island swallowed up by the black mist: working three jobs to support his paralyzed father and sick mother, depression followed him everywhere. He relied on a bowl of shredded pork rice from a stranger and the glimmer of a forum saying "Don't let your spine be crushed" to survive in a cocoon of low self-esteem.
The construction site is the new purgatory. In the roar of the master "Ma Yanwang", the ink line cut his fingers, the total station bent his spine, and the cold eyes and conspiracy followed closely. He swallowed the humiliation and gnawed on specifications and calculated data late at night in the boardroom when mosquitoes were buzzing. On the night when the cold wave struck, he independently directed the life-and-death battle of concrete pouring, pursed his cracked lips tightly, and finally won the master's shiny slide rule with a smooth and dense floor slab - the first concrete wall made of flesh and blood was erected.
The joy of the wedding was torn apart by the emergency sirens. The father collapsed, and the uremia diagnosis shattered the new life. In order to save his father and for the "little stone" in his pregnant wife's belly, engineer Chen Lifeng tremblingly accepted the dirty envelope. The muffled sound of the drawer closing is the collapse of the moral dam. On a typhoon night, the reporting email was like a life-threatening charm, and the tower crane groaned in the wind and rain. On the computer screen, an unfinished self-report letter is juxtaposed with an anonymous letter of betrayal from a classmate. Hovering the mouse, there is an abyss under the fingertips - and outside the window, the broken giant arm of the tower crane is smashing into the prefab area filled with inferior materials...
Under the concrete wall is a battlefield for survival in desperate situations, and it is also a monument to human dignity.
