Kim Sun checked everyone’s location in the control room. Tae-seok suddenly appeared and shot him. The two scuffled. Kim took a bottle of moon water and threatened him, but Tae-seok shot him and broke the moon water. She was locked in a room and watched him die. Zhian found a movie about her sister doing moonwater experiments in the research room. At first it was a goldfish, and later it was a copy of Luna with many numbers. It was not until the 73rd that she successfully adapted to the moonwater. The police also found out that her sister recorded it to her. In the movie, the sister said that she just wanted to help humans, and she wanted Zhian to see the sea, and Zhian cried. Zhian injected moon water into Luna's body to recover the wound on her foot. Jiarong fell from the vent to some place and found many of Luna's bodies, screaming in fright.
Yunjae and Soohyeok separate their actions. Yunjae meets Jiayoung and returns to the control room with Jiayoung. He sees Kim Sun's corpse. Yoonjae turns on the system to check everyone's location, and asks Jiayoung to return to the main researcher first. room. There is more and more water in the secret storage, causing the pressure in the cabin to increase, and the system automatically activates the ventilation system. Soohyuk came to Yuanjing's research room and pointed the gun at Runa. Yoonjae told Soohyuk that Tae-seok was heading to their location. So Soohyeuk quickly brought Ji-an and Runa back to the main research room, and Ji-an looked up. Look, the water dripping from the upper pipe dripped onto the face. Tae-seok came to Yuanjing's research room, but did not see anyone. Yuncai suddenly appeared to scuffle with him. Moon water suddenly broke through the Bohai base and sprayed on Tae-seok's body. Tae-seok hurried away.
