I’m a Mage Who Wields a Sword to Crush Villains. What’s the Problem?

【Empress by my side + play the pig to eat the tiger + genius + swordsmanship】 Jiang Xiaobai transmigrates to a world where humans and demons coexist. An Empress also lives inside his soul. He's tormented by the possibility that he might turn into a woman at any moment! After ten years of sword practice in the mountains, he accidentally comes down and is mistaken for a talentless nobody. He's assigned menial work at Jiangcheng Spirit Academy, only to get himself into serious trouble. Then, by a stroke of luck, he becomes a mage... Jiang Xiaobai: “I'm really just a low-tier mage!” Villain: “Who are you trying to fool? If you've got the guts, hit me with magic instead of slashing me with that sword... Wait, you're a woman?” Jiang Xiaobai: “Just take this sword first. I'll turn back into a man afterward...” 【Please note: this story includes a gender-transformation gag, though it doesn't happen often. Avoid it if that's not your thing!】
