My Basement Connects to Another World

[Seeking follows for the new novel, Reborn as a Great Painter!] Zhu Nanfeng discovers a wondrous otherworld in the basement of her own home. On the very first day of her trip there, she finds a little bundle of joy with green hair and green eyes, who doesn't look human. She cooks for him, makes his bed, and sings him to sleep. She raises him for half a year. The kid, who has grown all the way to six feet tall, finally speaks. He strokes her hair and gazes at her adoringly. "You've taken such good care of me. I'll take good care of you, human." "...What?" Zhu Nanfeng. Wait, let's get this straight. Which one of us is whose pet? Later... When otherworlders are being eaten as snacks by three-headed lion-yao beasts, Zhu Nanfeng travels between the two worlds, trading modern rice technology for gold and jewels from the otherworld. "The otherworld is short on food? I've got plenty!" "The otherworld is short on weapons? I've got plenty!" "The otherworld is short on medicine, salt, and everything else? I've got it all!" When her cousin's son is worrying about how to get around, she buys buildings with gold bricks and trades diamonds for cars. Back on Earth, she has a huge villa. In the otherworld, she has a grand palace. And so she lives a happy life, rolling around on mountains of gold. And Ji Xun, who decided to take her in, keeps his promise. He snatches immortal pills for her to eat like candy, forges a golden crown for her to wear as a hat, and beats every demon beast and spirit into submission, making them her minions to boss around. He even graciously grants her a new honor: "Your bloodline may be inferior, but I permit you to bear me a whole litter of cubs." Zhu Nanfeng, the world-hopping merchant who dominates the otherworld: "...Huh?" ...[The old novel, The Little Secretary System, is delightfully sweet and satisfying, with plenty to read!] Theme: Modern technology changes the world.
