MTL - My Stand-in is Steve - Chapter 441 Obtained material: Aizen's Collapsing Sky Jade

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? Or will he succumb into a conspiracy lurking within the country's borders?

Liang Ning had just bid farewell to her eldest and second eldest brothers who died on the battlefield, never expecting that when she was preparing to fulfill a marriage contract with an orphan she saved six years ago, she would be burned alive by him!Upon waking, she became Miss Fu of the Fu Family, and her murderer had already risen to a high position, surrounded by beautiful wives and concubines, becoming a trusted minister before the emperor...No fear!Miss Liang of the Liang Family changes lanes, still the decisive and ruthless Rashamon!But why does that brat, who used to play around with her nephew and knew nothing about respecting elders, keep pestering her?

In her previous lifetime, they had married for five years. He meant everything to her, but she was thrown away like an old shoe.

sidelines, cheering for the MCs like the dedicated shipper she is. But plot twist—she’s now a guy. And not just any guy—a ridiculously handsome guy!After spending an embarrassing amount of time winking at her own reflection and flexing muscles she never had before, she decides, “Why just watch the romance when you can be the romance?” Armed with good looks, charm, and way too much insider knowledge of every trope imaginable, she sets out to conquer every character in the story, including the MC she used to fangirl over.But wait… Does this make her gay? Or straight? Or just hopelessly in love with her own fictional fantasy? Frankly, she’s too busy causing chaos (and enjoying it) to care.PS: There is smut, and its reverse harem :3
