Lin Chen, a top special forces soldier, died heroically with his comrades after being betrayed by a traitor while performing a transnational anti-terrorism mission. As he lay dying, he looked at the fallen figures of his comrades, filled with regret for not being able to protect them. Unexpectedly, he was reborn and returned to the time when he was a recruit of the special forces "Blade" ten years ago. With the memories and battlefield experience of the next ten years, Lin Chen is determined to change his destiny. He wants to uncover the lurking traitors, make up for his previous tactical mistakes, and protect his comrades one by one; he also needs to make plans in advance to crush those conspiracies that threaten national security. In the tempering of blood and fire, he not only wants to restore the glory of the "Blade", but also makes the banner of loyalty and faith fly forever on the battlefield in the new era.
