After Losing His Husband, the Chaebol Uncle Had Been Planning for a Long Time

[Double male protagonists + Whistle power + Father's uncle + Widow's taboo + Premeditated ascendancy + Double strength and double cleanliness] Xie Jingshen is an S-class sentinel with incredible combat prowess, but he is forced to marry a sickly young master of the Yan family. Only seven days after the wedding, the young master died mysteriously. Everyone in Beijing was laughing at him, mocking him as a tough-minded "concubine's wife". On the night of the first seven days, Xie Jingshen returned to his old house to collect his belongings, but in the dark corridor, he ran into an extremely oppressive embrace. The person who came was the truly powerful head of the Yan family, the rumored brutal and ruthless SSS-level dark sentinel - Yan Beichen, who was also his nominal "little uncle". In the darkness, the rare 100% mutant compatibility caused the two of them to lose control at the same time. Yan Beichen's spiritual body, the black dragon, tightly wrapped around him. The man pinched the back of his neck condescendingly, his voice low and paranoid: "Ziyou is dead. As an asset of the Yan family, you belong to me now." Xie Jingshen thought this was a humiliating forced robbery, but he didn't know that there was a shocking mystery behind the seemingly unexpected loss of his husband. And this chaebol leader, whom everyone revered, fell into madness looking at his back in a dark alley ten years ago. ——All coincidences and accidents are just a trap laid by the superior for ten years, just to lure him into his arms.
