Xuan Ling thought of forever happiness when he was young. He was raised solely by his father, who had introduced him to the harsh world where only the fittest are meant to survive, he was trained by people who made him stronger each and everyday until he could finally stand on his own. Twenty-three years of presence in a military base, Xuan Ling suddenly lost his father and sworn bestfriend, He Yu. However, he did not suffer alone. Somewhere outside the base, a soldier who quit the military shadowed the city, wanting vengeance. Wang Yichen was also searching for a clue behind his father’s death six years ago. In their encounter, Xuan Ling and Wang Yichen discovers that they are not only bound by their common relationship with He Yu, but also, they are bound to unravel the secret of their fathers. Their fathers made a big mistake six years ago, bumping into a very dangerous opponent that not even the soldiers and cops could win against. When not even wealth can’t stop the feud, when not even a cup of tea is enough and when life gets gambled by a painful destiny that rested only for a few years... Suddenly, there was a story that I have to tell you. There’s a legend I have to let you know...
