When modern elites are trapped in a deadlock, when the sharp edge of science and technology collides with the internal force - this is not an exercise, but a life-and-death war for survival.
The special operations team codenamed "Dark Blade" triggered a space-time rift at the end of the mission, and all members fell into a familiar but completely different parallel world. This place has a modern outline, but it is home to warriors with deep inner strength, rivers and lakes who abide by the "hidden covenant", and murderous organizations that are ready to move in the shadows. Captain Ling Chen discovered that a strange silver dollar left behind by his grandfather was actually the focus of many forces in the world and was the only clue to their return to their lost hometown.
From being forced to join forces to fight against the conspiracy, to initially integrating modern thinking and ancient martial arts wisdom, Ling Chen and his team members embarked on an unprecedented path amidst the clash of swords and ideas. They used precise calculations to fight against mysterious techniques, used fearless sacrifices to interpret the meaning of protection, and used "wrong" methods that were not of this world to achieve achievements that astonished the entire world.
But this is just the beginning. The dark night has arrived and the lights will go out. The real struggle is about the recasting of order, the choice of path, and the ultimate question of what "guarding" is. Ling Chen knows that some debts must be collected by someone, and some nights must be broken into by someone - with my dark night, I promise you thousands of lights. This debt is willingly passed down from generation to generation.
