After I Transmigrated, I Won by Staying Close to the Yandere

Shen Lanqiao was accidentally thrown into a training camp for assassins. To reclaim her identity as an ordinary person, she killed and saved people in equal measure, becoming the mysterious Black-and-White Twin Fiends of the martial world.

During a trip to the capital, someone suddenly tracked her down. It turned out she was the daughter of a marquis. To save her family, she was granted in marriage to Lu Dianchen, the emperor's most favored Third Prince.

Not long after the wedding, Lanqiao discovered that Lu Dianchen's favor was a sham. The emperor had deliberately made him a whetstone to hone his own son. Lanqiao was unconvinced. Was His Majesty not worried that the whetstone might grind the blade away entirely?

See how two notorious villains, in the eyes of the world, stir up trouble and set things right in both the imperial court and the martial world.
