What's the name of the movie in which the temperature drops suddenly and it rains, and one person and one dog finally submerges the whole city?

The movie you asked is will smith's movie "I am a Legend". Ignorant humans are often the initiators of catastrophic events ... human medicine has invented a new virus that can cure diseases, but the virus has mutated, turning infected humans into living zombies. A large-scale virus broke out suddenly, and almost no one could stop it from spreading. No one knows where this terrible virus started, except that it is unstoppable, irreversible and incurable. Most importantly, it is man-made. ? Robert Nayville is an outstanding pathogen scholar in new york City, serving the US military. As a pioneer of government investment in epidemic vaccine research, he saw the virus raging in the street, but he could do nothing. This airborne virus finally enveloped the whole city at an irresistible speed, so that the President could only order the blockade of new york City and let uninfected people leave the city. As you can imagine, this practice caused great panic among the citizens, and new york was in chaos. Robert put his wife Zoe and his seven-year-old daughter Mary on a helicopter and left Jiaocheng, China, but witnessed the tragedy of their deaths ... At this time, death may be the best choice, because those infected but not dead have changed their bodies and become terrible creatures, and there is no longer any rational thinking. They live in the darkness and shadows under the city, avoiding the sun-they are passionate about fresh blood and meat. ? As a result of this disaster, new york became a dead city, and Robert became the only human here-somehow, his blood had innate immunity to this virus. Robert knows that he has two weapons to use, that is, his scientific expertise and his own blood. The experience of earning a living in the army helped him choose a lifestyle in this abandoned city, which is completely systematic. He insists on a lot of physical training every day, and he also sends out radio waves to ask for help or find survivors like him ... Robert is a very self-disciplined person, otherwise, normal people may go crazy in this extremely lonely situation. The only one who is still fighting alongside Robert is his most loyal partner, Sam, a German shepherd. During the day, Robert took Sam out to find life-sustaining materials, and then went to the laboratory to do research and send radio waves; At night, they shut themselves in a building as strong as a fortress and watched the monsters "feed" on the streets of the city. In addition to doing the same thing dutifully every day, Robert enjoys complete freedom in this "empty city": he can drive his sports car on the street; Playing golf on a fighter plane; Decorating his fortress with priceless jewels, even the most prosperous commercial street in the city center has now become Robert's own "back garden". As the last hope of mankind, Robert was driven by the only remaining task, that is, using the immune system in his blood to find a way to reverse the virus. Although he knew that he was facing a huge astronomical figure, he had no choice because his time was running out. Stage photo
