Zhang Tiansheng, a young man from a small town in the south, refused to lead a mediocre life after failing the college entrance examination. With his admiration for soldiers and his obsession with self-breakthrough, he resolutely boarded the train heading north and became a recruit. When he first entered the military camp, he was reduced to a "conformist soldier" due to poor physical coordination. His physical fitness was at the bottom, his internal affairs was poor, he was ridiculed by his comrades, he doubted himself, and he was trapped in a growing dilemma. Thanks to the strict guidance and heart-warming redemption of Li Tiezhu, squad leader of the recruit company, and the support and competition of his comrades such as Zhao Lei and Wang Hao, his tenacity was completely inspired. He practiced more late at night and gritted his teeth to break through the physical limits. He gradually got rid of the label of "problem soldier" and completed the basic transformation from "civilian" to "soldier". From the accumulation of conventional infantry battalions, to the life-and-death breakthroughs of special operations selection, to the hardening of the special operations brigade, Zhang Tiansheng has gone through extreme training, actual combat tests, overseas peacekeeping and other hardships. He has faced the sacrifice of his comrades, life and death choices and mission responsibility. With his keen observation and unyielding willpower, he has grown step by step from a clumsy recruit to a top special forces soldier, and won the title of "King of Soldiers".
