The door of the refrigeration room slowly opened with Barry's command, "There isn't much food and resources left, obviously not enough to support us for the whole winter," Barry , the captain of exploration team, said.

It is now late autumn in 5674, and the Earth's ozone layer is about to disappear. The oxygen on the ground is already very thin, and only 5000 survivors live in the underground city equipped with complete oxygen supply systems. There are many creatures on the ground have undergone mutations to adapt to environmental changes.

"I think it's time to go out and search for supplies, Captain," Sidra, the deputy captain of exploration team, said. "But now the mutated monsters on the ground seem very rampant. Would it be too dangerous for us to go out like this?" Fay said anxiously. "If there is no food, the situation for all 5000 of us will become dangerous. Human interests come first. Don't worry, Fay, we will succeed," Barry comforted.

Outside the armored car, there was a mess, with many holes on the ground smashed by meteorites, as well as the bodies of mutated animals that had been killed and devoured. The sky was pitch black, with only the lights of armored vehicles providing the only light.

Suddenly, the detection device of the armored car made a strange noise. "Oh no, a bunch of mutant monsters are approaching us," Sidra said. "How so? Isn't there a monster repellent system on our armored car? Fay exclaimed. Jaylan, sitting in front of the control wheel, said, "There are so many monsters that we can't handle it!" "I'll go with Cloe to lure them away, you guys get out of the way, trust me." Barry commanded. Cloe, who had been sitting silently in the corner, immediately picked up her equipment and followed the captain out of the armored vehicle.

"Captain and Cloe will be fine, right?" Fay said. "What's more important now is to find food, otherwise humans would really be in danger," Sidra said. "There seem to be signs of supplies on the right front," Jaylan said. "Good, full speed ahead," Sidra ordered.

The doors of the armored car slowly opened. "Fay stayed behind to pick us up, and Jaylan got out of the car with me to look for food." Sidra said.

Sidra turned on the light on her helmet and began to look around. "The detector seems to be over here," Jaylan said, pointing to the front right. They made their way to the place Jaylan was pointing, but instead of supplies, they were greeted by a group of mutated monsters. Sidra was startled, but immediately reacted, found cover, and hid. However, Jaylan stood motionless until the monster spotted him. Sidra thought to herself, "Oh no, we need to get back in the armored car." She hurriedly grabbed Jaylan's hand and planned to run in the direction of the armored car. But Sidra couldn't pull him, "Hurry up, they're going to catch up!" Sidra urged. Seeing that the way back was also surrounded by monsters, Sidra hurriedly pushed Jaylan and hid in a box.

"What's the matter with you, why didn't you move?" Sidra whispered, "I hope we won't be discovered, or the people in the underground base won't survive without food at all."

"I wonder if you remember Kari?" Jaylan's eyes glazed over and he whispered. "How do you know her, she was my teammate before, she was smart and brave, but unfortunately she died," Sidra replied. "She's my sister, my only relative, she's still so young, but it's you that killed her!" Jaylan said suddenly, emotionally.

"She was already infected with the mutant virus at the time, and if she returned to the base, she would only infect more people."

"There is obviously a possibility of treatment, but you killed her directly!"

"I can't gamble with the lives of everyone in the underground base, and I'm also sad to have lost an excellent comrade-in-arms."

"Hypocrisy! Let me tell you, I planned everything for today, and the monsters on the road were also attracted by me, and the captain should not be able to come back. I'll ask you one last time, do you regret your decision? ”

"No, human interests come first." Sidra said resolutely.

"Then you go to hell and confess to my sister!" With that, Jaylan detonated the bomb on his body. Seeing this, Sidra hurriedly dodged. Luckily, she jumped out of the box with only a slight injury. But the sound of the explosion caught the monster's attention, and Sidra gripped her gun and began the fight.

Sidra's badly wounded body appeared in the armored car lights. Fay exclaimed, hurriedly opened the car door, and helped her into the car. "What happened? How did you get so badly injured? What about Jaylan? "Fay asked quickly. "He's dead. I'm already infected, I can't go back to the base, you just kill me and hurry up to save the captain," Sidra said in a weak voice.

"No, the doctors at the base have just developed a new drug that has a high chance of being cured. I'll take you back, and you'll be cured! ”

"What is the cure rate?"

"70%, for sure."

"No, it's not high enough, don't waste your time, kill me quickly."

"No, I can't, I can't, you trust me, you'll survive when you get back to base," Fay cried.

"I can't gamble the lives of the 5,000 people in the base and the fate of humanity, human interests come first," Sidra said, using the last of her strength to turn the gun on herself and press the trigger.
