Three years ago, he was the supreme “Dragon King,” a legend in the underworld. But after being betrayed by his sworn brothers and left gravely wounded on the brink of death, he concealed his identity and married into the Su family of Jiangcheng, becoming a live-in son-in-law who delivered food and was despised by everyone.
Three years later, his wife is humiliated and her family pressures them to divorce. At their engagement banquet, he opens his grimy delivery box. One black card stuns the crowd, and a single phone call brings a powerful family crashing down overnight.
But before the turmoil has even settled, new threats are already brewing. A sky-high bounty on the international dark web once again puts a target on his back. The shadows of the bloody betrayal from years ago come surging back, while the ancient organization Dark River quietly casts its vast net across the city.
With formidable enemies closing in from all sides and his beloved wife at his side, he dials a long-sealed satellite phone and awakens the Four Guardians.
“Azure Dragon, White Tiger, Vermilion Bird, Black Tortoise, heed my command.”
As financial tycoons bow their heads, the queen of intelligence submits, and the king of military industry comes to pay homage, he takes his wife's hand and gazes down at the city, both familiar and strange.
The king has returned, the hidden dragon emerges from the deep. This time, he will reclaim not only the blood debt, but also the vast land that was stolen from him.
