Upgrade Specialist in Another World - Chapter 4: Slaughter in the Coliseum

At home, she was invisible; after marriage, she was a decorative vase; in the end, a sea of flames buried her, and not even her corpse remained. This is the portrait of Han Yuxi’s previous lifetime.

Given a chance at rebirth, she strives to improve herself, wishing only to no longer serve as a foil or a pretty face. Then, she will seek out an exemplary husband and live a life of peace and prosperity. Alas, things turn out contrary to her wishes—she marries a man who bears a blood feud and hatred as deep as the sea.

She turns the world upside-down, but her road to happiness is strewn with setbacks and the sweetness that comes after bitterness.

During her cultivation practice, Nie Yinzhi encountered a mishap and nearly fell into qi deviation. After emerging from seclusion, she discovered she could see floating subtitles above her head.From these danmu (bullet screen comments), she learned that she was merely a substitute supporting character in a novel.Everyone in her sect doted on and loved her only because her eyes resembled those of the beloved senior sister who had perished ten years ago.And in three days, that blind senior sister would return to the sect—Nie Yinzhi would have her core forcibly removed by her master, her eyes gouged out by her senior brother, and ultimately die alone.Armed with spoilers from the danmu, Nie Yinzhi set up a forbidden array, sacrificing her soul to summon the novel’s antagonist – the great Demon Lord.Covered in blood, amid everyone’s terrified gazes, she coldly smiled and said, “If that’s how it is, then none of you shall live!”The Demon Lord appeared slowly in his dark robes, reaching out to wipe blood from the corner of her mouth: “You’re so young, why harbor such deep resentment? If there are any misunderstandings, we can sit down for tea and talk things through. Why resort to violence?”Nie Yinzhi: “???”Is this the ruthless, evil Demon Lord everyone spoke of?![The Demon Lord says no with his mouth but his actions prove otherwise. Don’t worry, it’s not frustrating, feel free to dive in.]Gu Jiang: Today my wife is asking me to kill againNie Yinzhi: Today the Demon Lord is preaching virtue to me againCultivation World: Being persecuted again todayLaid-back retired veteran couch potato Demon Lord male lead VS grudge-holding can’t-take-any-grievance female lead[[Warning: As you can tell from the synopsis, the female lead isn’t designed to be morally good! She has character flaws! She’s not a perfect victim! She won’t wait until they actually remove her golden core and gouge out her eyes before fighting back! Proceed with caution if this bothers you!] ]
