She is a cultivator from another world. She is proficient in refining artifacts, improving elixirs, talisman arrays, medical skills, and even fortune-telling. Due to several unexpected tribulations, her reputation was tarnished and she became the second daughter of the Lu family who harbored ill intentions toward her future brother-in-law.What? She had just been reborn, and she was going to marry a ferocious man who was known as the living Lord of Hell and the second young master of the Mu family whose legs were disabled?! Fine! Since that man was so magnificent and fit her taste, she would marry him anyway! But what happened to his legs being inconvenient? Who was the man who would pounce on her from time to time at night and pamper her until she felt sore all over?! Who was the one that first spread the rumors? Would they dare to come forward? They would most likely be crippled if they did not kill him![In the modern world, the male and the female are both strong. From evil torturing to extensive face slapping, this story is filled with endless thrills. There are mythical dimensions, cute babies and even (not scary) supernatural occurrences. Both leads are immaculate and pure while the male lead is addicted to doting on his wife!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
