Genderbent Dragon Clan: What Do You Mean My Sister Is Chu Zihan?

[Chu Zihang gender-swapped + Lu Mingfei gender-swapped + single female lead + alchemy and dragon-slaying]

“An older sister and a desk mate are the best things in the world.”

So said Su Qing, the legendary creative genius of Cassell, a remarkably dependable alchemist, a human Doraemon, the only normal person in the Equipment Department, the beloved little sister of an Executive Department witch ranked above S-class, and the perfect high school desk mate for the pretty S-class junior Lu Mingfei.

“I’ve said it before: all my success comes from my own efforts. That applies to learning and discovering Dragon Tongue, upgrading and evolving my bloodline, and getting rid of my beer belly and digesting it.” Su Qing spoke with grave sincerity as the employees below nodded repeatedly.

So that’s how it is. The boss really works hard, just as they’d thought... Wait, did something weird slip in there?

“Boss, there’s a suspected high-level mixed-blood in northeastern Amerl, unleashing a dangerous Word Spirit with a wide area of effect!”

Su Qing’s gaze sharpened. “Do we know its sequence number?”

“It seems... to be in the nineties!” Her subordinate trembled with fear as Su Qing picked up her blade, her long black hair cascading like a waterfall.

“Warriors, charge with me and apprehend the criminal!” Su Qing called out to the System in her mind. “Is the analysis cooldown over?”

[Analysis cooldown has reset]

“Yes!”

“Charge!” Su Qing roared, brandishing her blade.

This is the story of an ordinary-blooded mixed-blood who unexpectedly obtains a Dragon Tongue analysis System, and struggles to survive at a school for monsters through alchemy and all-nighters, eventually forced to embark on the path of dragon-slaying.

(The pacing is on the slow side, with original plotlines. The protagonist influences events, and a certain cold-faced, cute, expressionless person learns to joke.)
