Before the burning pain of gunpowder smoke in his nasal cavity dissipated, Lin Xiao was awakened by the biting chill. He opened his eyes suddenly and saw a mottled cement wall in front of him. "August 2008" was clearly printed on the old-fashioned wall calendar - this was the eve of his first special forces selection. A strange warmth suddenly came from the palm of his hand. When he looked down, he saw a faint spring pattern emerging from the tiger's mouth. At the same time, memories came flooding back like a tide.
In his last life, while performing a cross-border rescue mission in the Middle East, he was hit by an IED bomb while covering his teammates. Before he died, the last scene he saw was the recruit Danzi who always followed him and called "Brother Xiao", holding him and crying. But now, he has returned to fifteen years ago.
