Xiao Yi and several other survivors stood in the mission hall, about to embark on an unknown journey. The base's leader, Li Hao, explained the mission in detail: to search for supplies in an abandoned supermarket on the edge of the city. After the apocalypse, the supermarket had become a zombie territory, and the supplies inside were crucial to the base's survival.

As the sun gradually set, they set out on their journey. Along the way, they advanced cautiously, avoiding zombie gathering places. Each person's face was filled with tension and vigilance, weapons gripped tightly, ready to respond to any emergency.

The edge of the city was already a ruin. The buildings on both sides of the street were in ruins, with broken doors and windows, and the walls covered with vines and moss. Zombies roamed here, their eyes flashing red and emitting low roars. Xiao Yi and his teammates advanced closely in the shadows of the ruins, trying to avoid being discovered by the zombies.

After a long journey, they finally arrived at the supermarket. The door stood open, and the interior was pitch black, with only a faint moonlight filtering through the broken windows. They knew it was fraught with danger. However, for the survival of the base, they had to face it bravely.

Xiao Yi took a deep breath and raised his rifle. He rushed into the supermarket first, followed by his teammates. They turned on their flashlights and illuminated the interior of the supermarket. The goods on the shelves were scattered all over the floor, and the ground was covered with dust and broken glass. They began to search the supermarket carefully, looking for useful supplies.

Suddenly, a burst of hurried footsteps came from deep inside the supermarket. They immediately became alert, holding their weapons tightly. A group of zombies rushed out from the darkness and attacked them. Xiao Yi and his teammates quickly launched a counterattack. With their extraordinary courage and wisdom, they successfully repelled the zombies' attack.

However, this was just the beginning. In the supermarket, they encountered more dangers and challenges. Sometimes they were besieged by hordes of zombies, sometimes they were hidden traps and traps. But no matter what difficulties they encountered, they never gave up. They supported each other and worked together, ultimately successfully finding the supplies they needed.

When Xiao Yi and his teammates returned to the base with a full harvest, they were warmly welcomed and praised. This mission not only allowed them to obtain valuable supplies, but also made them deeply realize the importance of teamwork. They knew that in this doomsday world, only unity and joint efforts can help them survive.
