A man in his fifties can still be a warm-hearted man

Everyone assumed Chu Chengyuan was just an unremarkable old ground crew worker at Jiangcheng Airport, enduring the disdain and mockery of others. Little did they know, he had a past that would leave anyone speechless. Once, he was the fierce protector of the land, a national hero who safeguarded the entire nation with countless military achievements. But to quietly enjoy watching his young granddaughter grow up, he resolutely abandoned all power and glory, retreating into the mundane life of the common folk, seeking only a simple and stable existence. However, his greedy and malicious daughter-in-law, who betrayed the family's trust, colluded with wealthy businessmen to humiliate him repeatedly, even mistreating his beloved granddaughter. On top of that, influential figures from all walks of life conspired to bring him down. The relentless malice shattered his tranquility, pushing him to his limits time and again. The fierce warrior, long lying in wait, was bound to return to the spotlight, causing an upheaval that no one could ignore.
