My CEO Mom Married a Security Guard

Five years ago someone set Samantha up. She was the young heiress of the Shen family, and the trap left her spending one night with Landon, a man who had just left the army, where he had been called the Ultimate Soldier. She had his daughter, Sabrina, and raised the girl on her own. The Jiang family now means to marry Samantha to its heir. To get out of it she takes Sabrina and goes looking for the child's father, finds Landon, and the two of them marry in a hurry. He takes a job as a security guard at Shen Group and tells nobody there that he is the Dragon Lord. The company is short of money, the Jiang family is working against it, and behind the Jiangs stands the Blackstone Society. The Qin family, for its part, is mixed up in what happened to his sister. When Shen Group is in trouble the new guard steps in, and more of what he can do comes out each time, including a flying knife he is known for.
