Hua Manman never expected to transmigrate into a satisfying palace-intrigue novel, becoming the cannon fodder female supporting character in the book.She tried to turn the tables, but discovered that as long as she didn't act according to the plot, she would feel a heart-wrenching pain as if being stabbed by a knife.In that case, she might as well just lie flat and be a salted fish!But what was baffling was,why did that Prince Zhao, known for being sinister, ruthless, and treacherous, always like to stare at her?...Prince Zhao discovered that something seemed to be wrong with his ears.As long as he stared at someone, he could hear that person's inner thoughts.For example, right now,Hua Manman was crying with tears streaming down her beautiful face: “To be able to receive the Prince's favor is truly a blessing this humble servant has cultivated in a past life!”However, what she was thinking in her heart was—“Oh my, this chili oil today has quite a kick! It's making me cry so hard I can't even stop.”...(1v1, Sweet)

The mighty heavens exist, ruling over all things. Those favored by its will are granted power and fortune, while those who dared to oppose it perished, leaving none behind. This is the tale of a man who once defied the heavens, underwent multiple reincarnations, and returned once more to the cultivation world. But here’s the twist. This young man remembers nothing of his past lives and is simply a teenager from Earth. How will he who has no knowledge of cultivation and experience in fighting, survive this grim world while being an inner disciple of a lower realm force—or so Xiao chen, the teenager thought till he heard a systematic sound in his mind. [Ding! Host has awakened the heaven’s destined villain system!]

The daughter of a duke, the stuttering Maximilian, married a knight of lowly status at her father’s coercion.
