When the cold river water submerged the last ray of consciousness, Su Yu was reborn back to the age of fifteen with overwhelming hatred. She was framed by her stepmother and stepsister in her previous life and became a victim of her family. In this life, she vows to firmly hold her destiny in her own hands.
She gave up her cowardice and hid her edge, and she resolutely chose the most difficult military road. From receiving secret training from retired sniper Grandpa Luo, to joining the Special Forces Reserve as an exception; from becoming the King of Special Forces code-named "Thorn" to being selected into the top secret organization "Deep Blue" - she has grown rapidly in the tempering of blood and fire.
Along the way, she met Lu Jingnian. This powerful and mysterious special forces commander, from initial scrutiny to heart-to-heart teaching, eventually became her most solid support and most compatible soul mate. They fought side by side, writing the love legend of "You and I are invincible in the world" amidst the hail of bullets.
The truth about his mother's early death and the secret past of the Lin family in Beijing gradually emerged. Facing the intricate family forces and enemies hiding in the dark, Su Yu holds a sharp blade and wears glory, vowing to liquidate those who have hurt her and the people she loves.
This is a road paved with thorns, and she will eventually step on the thorns to reach her peak.
