Mr. Zombie lingers in the city

Five Rules for Modern Zombie Survival (To be Supplemented): 1. Never drink human blood except in emergencies!!! The risks are extremely high, and the energy conversion rate is almost the same as animal blood, making it very inefficient! 2. Zombies don't have stomach acid. When you need to eat for social reasons, remember to eat foods that induce vomiting easily. Avoid hard foods, as they can choke you! 3. Don't assume you can avoid beef just because you're physically strong. You don't want to know how cruel large-caliber firearms are. 4. It's best to cultivate your own blood. Be careful of blood with high cholesterol and high blood sugar. It tastes bad, and zombies have a very low absorption rate of cholesterol and blood sugar, so you might have to bleed them out – not worth it! 5. Don't casually provoke women, because zombies have difficulty distinguishing between desire and appetite. Getting them dizzy is one thing, but killing them is another… Also, women can make zombies unhappy, especially unattractive ones…
