My Husband's Golden Finger

This book has two male leads, and both have golden fingers. An alien transmigrates to the Tang Dynasty in ancient times. There, he meets a handsome young prodigy from the neighboring manor. Inventing things, making discoveries, farming, and supporting the family: they do it all. If you’re rich enough to rival a nation, you can treat money like dirt. But are they rich enough to rival a nation yet? Not yet. So for now, they can’t treat money like dirt. With a xiao flute and a sword, they roam the world. They visit miasma-ridden Lingnan, and take the opportunity to cure malaria; They visit bustling Chang’an, and take the opportunity to make an impression on His Majesty, Li Er, and show off a little; They visit Europe to see its backward technology and barbaric nobles, and take the opportunity to bring back a haul of local specialties; They visit the Americas for potatoes, sweet potatoes, tomatoes, and quinine… Good grief, why are there so many wonderful things? Maybe they should set up a base here.
