Modern special forces soldier Sedrick is reborn as Summeria's infamous playboy heir. Betrayed by his wife Sylvia on their wedding day, he unlocks an intelligence system and begins his climb to power. Outsmarting the Third Prince's rebellion, manipulating the royal court, and uncovering the truth behind his father's death, Sedrick turns the empire's internal conflicts against the Jiang royal family and seizes the throne for himself.
A soldier who died on an overseas mission transmigrates into Summeria's useless prince. His new wife Sylvia, deeply in love with Jacob, sets 30 harsh rules and plots to steal his family's military power. An intelligence system activates, exposing her scheme—watch how he turns the tables!
On her wedding night, Sylvia faces a cruel ultimatum from Sedrick: return the million-tael bride price to stay as a concubine or be cast out. When Jacob arrives to rescue her, Sedrick threatens to spread scandalous rumors and flaunts his new Northwatch Prince status to intimidate her.
Wrongly accused of theft at the Prince’s Manor, Jacob is brutally beaten by guards. He claims he’s Prince Jacob and recalls childhood cricket games to convince Sedrick. But Sedrick revives a bitter old memory—Jacob once forced him to swallow a cricket after a match, leaving him bedridden for three months. Now, Sedrick orders guards to settle both old and new scores by beating Jacob again.
After his father’s passing, Jacob confronts a prince who intrudes his manor and tries to take his wife Sylvia. The prince taunts Jacob, claiming Sylvia loves him more. When forced to choose, Sylvia picks the prince, leaving Jacob devastated—until a secret twist reveals her hidden motive.
After rejecting a greedy million-tael bride price demand, the noble confides in loyal steward Zara about feigning weakness to avoid the Emperor's wrath over his military might. He takes charge of the Tiger Tally to command northern troops, orders a mobilization, and gets an unexpected visit from his father-in-law.
The Duke is blackmailed for a million taels dowry, with his son's massive gambling debt used as leverage. Meanwhile, the Emperor plots to seize the Northern Army's Tiger Tally via Syed, and the Duke reacts sharply when pressured to hand over the token.
A fierce confrontation erupts when an imposter posing as the Duke is exposed. The Third Prince laments Sedrick's cruelty to Duke Syed, while the King discovers Sedrick's scheme to claim the Northwatch title via public pressure. The Prince then unveils a counter plan.
After shocking the old man with the bombshell truth that he’s not his son, the protagonist activates a mysterious system to retrieve critical political intel. He uncovers Third Prince Jacob’s plot to smear Prince Scotty’s legacy, Minister Shane’s messy family turmoil, and Jacob’s strained marriage. He then schemes to recruit Shane and confront foes targeting his woman, sparking a thrilling counterattack.
Frustrated by her neglected life due to husband Jacob's condition, Dora is approached by playful noble Sedrick, who claims to have a miraculous pill 'Passion Gu' to cure Jacob. He tries to prove its effectiveness, warns of the pill's one-day expiry, and just then, Minister Shane arrives.
The young lord summons Minister of War Shane, confronting him over skipping his late father's funeral. He exposes Shane's secrets—illegal gambling dens and an affair with a royal consort that produced an illegitimate son—to coerce Shane into allying against the emperor. Revealing the emperor and Jacob's plot to frame his father using the Blood Raven, he promises Shane a duke title for helping foil the scheme.
Prince Scotty's spirit returns to the capital after falling in battle. While some mock his loss of backing and hint at Fabian's plot to undermine the Prince's Manor, the ominous blood raven sparks curse rumors. A loyal voice defends Scotty as Summeria's hero, pressing Sedrick to reveal hidden truths to the emperor and people.
Suspicion swirls over Prince Scotty’s mysterious death, with whispers targeting the Xiao family or Sedrick. A device used to fake ill omens surfaces, leading the culprit to confess being ordered by Commander Walter and Prince Jacob to frame the Xiao family. Jacob begs his father for protection, who defends him, teasing a tense retribution ahead.
Chaotic cries for help fill the air before General Luth confronts the monarch, revealing the late prince’s restless spirit and denouncing those who used bad omens to slander him. He warns that the million Northern Army stationed outside the city will not accept injustice unless the king immediately appoints the heir as the new prince to uphold justice, ease public unrest, and stabilize troop morale.
The king delays naming a new prince due to his late brother's recent death, but Sedrick argues state affairs take priority and pressures him with a million Northern soldiers, winning the acting Prince of Northwatch title. He soon grows wary of plots and rivals eyeing the official title in the coming month.
Following his father’s passing, the newly appointed acting prince calls out two insincere officials who only arrive to curry favor with his new status instead of mourning. He then strikes a pact with the Minister of War, who publicly backed him, securing a powerful ally as he prepares to officially inherit his title in a month.
His Highness pulls a witty calligraphy trick: a word that looks like an insult to Lord Shane flips into a glowing praise. He offers to legitimize Shane's bastard son, then demands Shane's life savings as a 'mourning gift' before letting him sneak out to avoid factional princes.
Freshly inheriting his title, Sedrick sees through the First Prince's fake condolences—he’s actually here to win Sedrick’s backing for the crown prince race, as Northern Army support is critical. Sedrick plans to extort funds, but the prince’s massive gold offering quickly turns his attitude around.
As Prince Scotty's heir and northern troops commander, Sedrick gets gifts from brothers: a valuable sword, harem access, and a scholarly book. Enraged by the ninth prince's 'insignificant' gift, he dismisses him sharply, revealing tense royal rivalries.
Jacob incurs the King's fury when his failed scheme to frame the Prince's Manor brings shame to the royals. Despite appeals, the King orders him flogged. Later, the King hatches a plot to eliminate Sedrick, heir of the Prince's Manor, believing his death will let him seize control of the Northern Army, and demands a body examination.
The revered ninth-rank Old Master dies suddenly. An autopsy reveals his organs completely shattered, implying he was killed by at least ten eighth-rank experts. Suspecting the Emperor's betrayal, a Xiao family member vows to secure the Northwatch Prince title, avenge the Old Master, and reclaim their lost power.
