In the dark underground garage, Li Eunhyuk and his companions drove their vehicles, but unexpectedly became the prey of many monsters.They drove towards the exit in panic, and the roars and crashes of monsters came one after another. It seemed that every impact was announcing their impending doom.

Just when everyone was about to be caught by the monsters, An Jixie appeared with a musket. He sprayed flames at the monsters without fear, temporarily giving his companions a chance to escape.However, the danger has not been eliminated and they must find a safe shelter as soon as possible.

On the other side, Jin Xiuying was surrounded by spider monsters, and her life was in danger.Everyone hid in a safe place and closed the doors and windows tightly, trying to avoid the monster's pursuit.However, Park Yoo Ri resolutely decided to go out to rescue Kim Soo Young. Lee Eun Yoo followed closely and asked those who were hiding: What is the purpose of this exercise?Is greed for life and fear of death the only way to survive?

Park Yoo Ri and Lee Eun Yoo bravely fight against the spider monster, while Ahn Sun Young, Cha Jin Ok and Kim Ji Eun also join the battle.Jin Xiuying picked up the Molotov cocktail and threw it at the spider monster, and the monster's screams echoed through the garage.At this time, Cha Xianxiu and others arrived in time and stabbed the spider monster with an electric knife, bringing this thrilling battle to an end.

After the battle, everyone was in a state of shock.Although Cha Xianxiu successfully killed the spider monster, he planned to return to the isolation room.Jin Zhien looked at Cha Xianxiu's back and said softly: “I'm sorry for making you feel even more uncomfortable.”Li Eunhyuk told Cha Xianxiu that it was up to him to decide whether to stay in the isolation room this time.In the end, Cha Xianxiu chose to leave the isolation room and face the next challenge with everyone.

When Park Yoo-ri was dressing Jung Jae-hun's wound, Lee Eun-yo noticed her difficulty breathing and guessed that she might have asthma.Park Yoo Ri revealed her condition during the conversation with Byun Sang Wook and bandaged his wounds.At the dining table, Cha Hyun-soo, Byun Sang-wook and Anji-seop were sitting together. Anji-seop infected Cha Hyun-soo and Byun Sang-wook with his positive energy, rekindling their hope.

When Lee Eun Yoo was bandaging his sprained ankle, Lee Eun Hyuk took the initiative to help.When Lee Eun Yoo discovered that Lee Eun Hyuk's glasses frame was broken, she repaired his glasses without hesitation.Jin Yingxiu pestered Jin Xiuying to play with her, but Jin Xiuying wanted a weapon that could kill monsters to protect her younger brother.Li Eunhyuk told Han Douzhi that the water tank was contaminated, and took him to the basement to modify the vehicle to deal with monster attacks.

The army spared Xu Yijing and reached an agreement with her, giving her an alarm.Jiang Chengwan discovered the shortage of food and water in the monitoring room and began to waver.He tried to prevent Cha Xianxiu and others from escaping privately, but was stopped by Byun Sangyu.Li Enhyuk announced his plan to go out and asked An Jixie to investigate the surrounding situation.Han Douzhi began to modify the vehicle in preparation for going out.Yoon Ji Soo played the guitar, while Cha Hyun Soo was immersed in the music and felt the warmth of home.

However, Yoon Ji Soo collapsed in the toilet the next day.After Lee Eun-yo's diagnosis, she learned that she had appendicitis.If not treated in time, Yoon Ji-soo will be in danger of life.Li Eunhyuk decided to perform a simple operation on her and informed her that she would need anesthetics, antibiotics and other items.Byun Sang-wook, Park Yoo-ri, and Cha Hyun-soo decided to go out and look for these items, while the others were busy preparing for the surgery.
