Write a mini-novel with horror, futuristic plant lunatic gunfight
In the future, plants have evolved into intelligent creatures. They have begun to think and act independently. However, these plants did not obey human orders and were suspicious of humans. One day, a madman suddenly appeared in a small town with a gun and started shooting at people. The people fled in horror, but the madman chased them all the way. There was a girl named Mary in this small town. She was the only doctor in this town. Mary was shocked by Madman's gunshots, but she still decided to help those who were escaping. When Mary arrived at Madman's hiding place, she found that Madman was not an ordinary person but a vegetable. His body was made of plants, but his mind was crazy. Mary decided to work with Madman and they began to treat the people who had been shot by Madman. However, the treatment process did not go smoothly. Some people began to feel fear and uneasiness. Under the efforts of Mary and Madman, the people in the town gradually became safe. However, the madman started to get crazier and crazier. He kept shooting at people, trying to kill them all. In the end, Mary and Madman won in a gunfight. In this battle, Mary used her wisdom and courage to defeat Madman. She successfully sent Madman to the hospital for treatment. The people in the town thanked Mary gratefully for becoming the hero of the town. Although the madman's behavior was chilling, Mary's courage and wisdom made her the most respected person in this town.
