Swordsman of Great Power

This is a realistic patriotism story. Swordsman Hei Tiezi's childhood, teenage and middle-aged stories. In the autumn of 1985, Hei Tiezi, a young university teacher with all-round talents in both civil and military affairs, came to Shekou, Shenzhen in order to make money to treat his parents. Because he was young and had no social experience, Hei Tiezi was coerced into joining the local underworld in Shekou and became his elder brother's bodyguard. Hei Tiezi has never had a fight in school or in society, and he cannot survive in the underworld. Later, Heitiezi assisted the military in completely smashing this underworld gang and became a secret soldier. After three years of training, Heitiezi was sent abroad to pursue a group of fleeing spies and traitors. After returning to China, he fought back against foreign killer groups in border areas. At the same time, spies at home and abroad are constantly being hunted down to protect state secrets. During the mission of hunting foreign killer groups in the uninhabited areas of Tibet, Hei Tiezi met Ye Lingling, a life-and-death comrade, and formed a deep friendship. It was not until many years later that Hei Tiezi learned that Ye Lingling was the twin sister who was secretly given away by his father while his mother was in a coma due to dystocia... Hei Tiezi never knew about this, not even when their mother was dying!
