My Sister Is Unstoppable

Northern frontier general Xia Bing rushes straight from a covert mission to her sister Xia An's engagement banquet, still in her mission coveralls. Mistaken for a cleaner by another guest, she is publicly insulted but calmly brushes it off and walks away. When she finally arrives, Xia An spots her and rushes to greet her.

At the engagement banquet, Sun Haoming mistakes coverall-clad Xia Bing for a cleaner and insults her, until Xia An publicly reveals she is her sister. Xia Bing warns him that anyone who disrespects her sister gets no second chance, and the two recall years of looking out for one another.

After mocking Xia Bing's coveralls, Sun Haoming orders his men to drag her away and teach her a lesson, and his thugs try to force her to serve them. Xia Bing stays calm and turns the tables, leaving the men to face the consequences.

Sun Haoming's men realize Xia Bing is the northern frontier general, rattling him as he excuses himself to call Pei Zhan. Xia An tells her sister that Sun Haoming doesn't deserve her, prompting Xia Bing to introduce the Pei conglomerate's Pei Zhan instead. Xia An doubts she matches his status, but Xia Bing insists on summoning him.

At his engagement dinner, Sun Haoming begs Pei Zhan to attend, while Xia Bing cuts in and has him pass along her name instead. He dismisses her as a poor nobody and a cleaner, worrying Xia An, who urges her sister not to cause trouble; Xia Bing agrees to call Pei Zhan privately later. Overhearing that this cleaner somehow has Pei Zhan's private number, Sun Haoming grows suspicious of who she really is.

Xia Bing calls Pei Zhan and offers to introduce her sister Xia An; he happily agrees and heads to the hotel. When Xia Bing herself arrives, Sun family members block her at the entrance, mocking her as a cleaner sneaking in for free food, until Xia An rushes over.

Sun family members publicly mock Xia Bing as a cleaner sneaking in for food and demand she kneel to get her invitation back. Xia An rushes in and, ignoring the Sun family's anger, declares in front of everyone that Xia Bing is her own sister.

The Sun family keeps mocking Xia Bing as a mere street cleaner unworthy of being Xia An's sister. Xia An hits back, insisting her sister's earnings are honestly made and that she owes everything to her. Xia Bing calms her down, dismissing the Sun family as beneath notice, which only draws more insults from them.

At the engagement banquet, the Sun family claims Xia An was once an orphan and now demands an entrance fee from Xia Bing, mocking her cleaner's uniform as unworthy. When Xia An offers to pay, the Suns sneer that she has no money. Xia Bing cuts in and names a price of 8.88 million, stunning the room into silence.

Old Madam Sun admits she only approved the engagement because Xia An could help the Sun family's finances, and mocks Xia Bing as a mere cleaner with no money. Xia An offers to cover the fee herself, but Xia Bing simply phones someone to prepare 8.88 million yuan on the spot, exposing the Suns' own cash crunch and leaving them humiliated.

Sun Haoming privately assures a woman that marrying Xia An is only a means to money, promising he won't abandon her. The two clash over who is really the mistress, trading threats about the Sun family's financial troubles. A woman from the Wang family then arrives with a huge cash gift for Old Madam Sun, instantly winning her approval and casting doubt over Xia An's engagement.

Sun Haoming turns on Xia An in front of everyone, and his family mocks her as worthless, even sneering that her sister is a street sweeper, before offering her a servant's job instead. As the Suns scramble to impress the arriving Pei Zhan, someone suddenly declares their wedding banquet cannot go forward.

At the engagement banquet, the Sun family publicly mocks Xia An as worthless and calls Xia Bing a madwoman and a street sweeper. Unshaken, Xia Bing openly confirms she is the northern frontier general and refuses to back down. As wealthy guests begin arriving, the Suns keep up their jeers, raising the tension.

Board directors arrive at the engagement banquet but hesitate outside, and the Sun family assumes the guests have come to honor them. A Sun family member mocks Xia Bing again as shabby and unlucky, but she fires back that they are the ones who should leave, and the scene suddenly turns chaotic.

At the engagement banquet, Old Madam Sun publicly mocks Xia Bing as a mere cleaner while claiming Xia An's company is collapsing and losing executives. A bystander defends Xia Bing, hinting her true status is far greater than anyone realizes, leaving the Sun family stunned and demanding she reveal who she really is.

The Sun family publicly grills Xia An, implying she bought bystanders' loyalty through improper means, and she denies it despite their mockery. Someone steps in to rebuke the family's disrespect, but the Suns boast that Pei Zhan will side with them once he arrives, until Xia An coolly asks how they can be so sure he won't be on her side instead.

Pei Zhan's arrival reaches the Sun family gathering, but they mock Xia Bing for thinking he would ever side with her sister Xia An. Unfazed, Xia Bing announces she will speak to Pei Zhan herself and formally introduce him to Xia An, daring the Suns to watch the outcome unfold.

At the engagement gathering, Sun Haoming mocks Pei Zhan as a penniless street sweeper, only to be told Pei Zhan actually heads one of Jiangning's top conglomerates, leaving him speechless. As Xia An tries to pull her sister away, Sun Haoming turns and hurls insults at Xia Bing, escalating the confrontation.

Xia Bing formally introduces Pei Zhan to her sister Xia An, and he reveals he has already resolved her company's crisis, pledging an immediate hundred-million investment. News then breaks that a rival firm has suddenly collapsed after its owner's daughter angered the wrong person, hinting at a shifting balance of power.

After a rival firm's collapse, the Sun family blames Xia An, hurling insults at both sisters and sending someone to attack them. Xia Bing steps in to warn them off, but the Suns boast about their conglomerate's status, so she coolly promises they're about to find out exactly what she's capable of.

The Sun family realizes they've enraged Xia Bing, the frontier's top general, and scramble to apologize. Xia Bing leaves Xia An in Pei Zhan's care, telling her to use the time to get to know him, while she goes off to find something to eat. At the restaurant entrance, an unexpected stranger suddenly turns up, unsettling the scene.

Still wearing her mission cleaning uniform, Xia Bing arrives at a five-star hotel to meet a friend but is mocked and blocked by staff who assume she can't be a VIP guest. Instead of losing her temper, she calmly reveals she has something that changes the staff's attitude, leaving the confrontation hanging.

Still in her cleaning uniform, Xia Bing is mistaken for her sister Xia An by old classmates, who mock her for becoming a cleaner and exclude her from their reunion. Hotel staff keep refusing her card until an employee recognizes her as a friend of the boss's daughter, shifting the standoff.
