Irregular Monster Girl Doctor

"Travel to a world full of monster girls and get a golden finger that absorbs diseases and turns them into words. What kind of life do you want?" "A, it is our duty to rebuild the glory of mankind and continue the bloodline of the monster mother, the royal family and the saint." "B. Destroy the demons, defeat the tide of monsters, and become a hero who saves the world." "C. Explore the dungeon, unlock the secrets of this world, thwart the mind flayer's conspiracy, and seal the evil god three times." "D, become the master of the plane." "Children make choices, I want them all." As his strength continues to improve, Lewis gradually comes into contact with the dark side of the world. Ancient technology, bloodshed, alchemical weapons, lost empires, ancient ruins, abandoned cities. While people in this world were still doing reverse archaeology, Lewis was shocked to realize that there was a pair of big hands hiding in the darkness that were ready to crush the entire world.
