Lin Chen, the ace captain of China's "Blade" special forces, codenamed "Lone Wolf", spent his life on the battlefield, performing thirty-three top-secret missions with a narrow escape from death. However, during the last border defense operation, he was betrayed by his most trusted deputy captain, Zhao Feng, and died in the siege of an international mercenary group. When he was dying, he closed his eyes and sank with regrets about the unavenged blood revenge and the safety of the country. When he opened his eyes again, Lin Chen was reborn and returned to the new barracks in 2010 - eight full years before he stepped into the "Blade", sacrificed his comrades, and rebelled against traitors. This time, with his ten-year peak memory as a soldier, top tactical experience and accurate prediction of the future, he showed his amazing talents starting from the basic assessment in the new barracks: breaking the five-kilometer cross-country record, crushing veterans in push-ups, and scoring full marks in all five live-fire shootings, which shocked the entire camp. He is no longer a young boy who only charges with passion. While he is fighting through the cruel selection of special forces, he is trying to make up for his past regrets and protect his comrades who are alive and dead. At the same time, he is making secret plans step by step, vowing to completely smash the conspiracy of the traitor Zhao Feng and the international mercenary group. From being an "alien" in the new barracks to returning to the pinnacle of "sharp blade", Lin Chen used his reborn body to hold the blade of vengeance and guard the territory of his family and country. In the tempering of blood and fire, he recast the legend of the King of Soldiers, making all the young people scared!
