Done! I'm Surrounded by Witches

Dr. Xi, who has been traveling around the world for more than ten years, runs a "rebirth" clinic in the most chaotic city of freedom. One day, when Mr. Xi was closing the door after get off work as usual, a silver-haired witch came to him... The arrival of the witch brought devastating disaster to the Free City. Our Doctor Xi fled all the way to the northwest and came to an extremely closed country. In this ignorant and backward country, he embarked on the path of practicing medicine again... What to do if there is no ventilator? There is slime! What to do if there are no surgical sutures? Spider with a human face! What should I do if I don't have CT equipment? There is a demon sealed artifact! What to do without antibiotics? Go to the cemetery and pick some human head mushrooms... Do you want pointy ears? Can! Do you want elf ears or goblin ears? What? ! You want the goblin's green ears? ! Your Majesty, the dragon egg in your body is too big and you need a caesarean section... Lord Balrog, your heart keeps spitting fire, melting my scalpel... Ps1: There is no woman in my heart, so I will draw my sword and be a god of nature. Ps2: Magical creatures are so useful! Ps3: Not good! I accidentally created a bunch of witches! Ps4: Bring hundreds of millions of shocks to this different world with backward medical science! (Don't criticize if you don't like it! The author has a heart of glass that will break if touched.)
