The Fierce Big Wolf and His Precious Little Fox

Two male protagonists, two strong men, 1v1 double cleansing, criminal investigation, arrogant and noble young master shou VS an old ruffian male attacker who loves to show off and talk coquettishly but is also very serious at times. Three years ago, Merchant Tour was seriously injured in an explosion and was rescued by a stranger. Three years later, Shang Xun met that man during a major case. It's just that one person recognized him, but he didn't. The two met during this corpse dumping case. He saw how thoughtful he was under his wild and unruly appearance, and he also saw another side of him that no one knew about. A little fox who seems cold, dignified and has a bit of a temper, but is actually a madman who can see people's hearts thoroughly. One of them seems to have no integrity and loves to talk nonsense, but in fact he is thoughtful and has skills like a fierce wild wolf. The cases are connected one after another, one after another, and after each one is connected together, the victim forms a closed loop. Someone asked the merchant: "Your parents have died, and you are about to die, so are you afraid?" The businessman chuckled lightly. No one was doing anything right, but his eyes were firm and fearless: "When have I ever been afraid? I should not give in an inch!!" Note: Plot is the main focus, emotion is secondary.
