The shortage of water resources, coupled with pollution, caused food shortages. The government banned pets and implemented a drinking water grading system, causing people to protest. Jin Zixuan, the section chief of the Korea Aerospace Exploration Agency's resource group, came to the Institute of Living Environment and told Song Zhian that Director Cui recommended her to take part in the mission of Bohai Base. Zhi'an remembered his sister Song Yuanjing, who died at the Bohai base five years ago due to a radiation leak. A total of 117 researchers were killed that year. Director Cui gave Zhi'an a golden membership card after the accident. Zhi'an poured water on the ground. Suddenly a puppy ran out to drink water, and Zhian kept it secretly ever since. The crew of the space exploration team includes captain Han Yuncai, Dr. Song Zhian, engineer Liu Tae-seok, team member Kong Xiucan, driver Jin Shan, co-pilot Yin Zhiyong, doctor Hong Jiarong, consultant Huang, who has been to Bohai Base, and Xiucan’s brother and security guard Team leader Kong Xiuhe, team members E1 and E2, after the mission, everyone’s drinking water ration can be upgraded to B. The mission is to find samples stored in extremely low temperature capsules in three storage warehouses within 24 hours before the Bohai base is closed. I asked what kind of sample it was, but Director Cui said that the information was lost during the radiation accident, so Zhian would be invited to participate if he didn't know the sample. Yuncai said that as long as the task was completed, Director Cui said that decisions related to the sample would be handed over to Zhian.
On the day of departure, the first officer suddenly changed to Li Qixiu, and everyone boarded the Nuri 11 spacecraft. Before landing, the spacecraft suddenly became abnormal and could not contact the Aviation Administration. Yuncai asked to remove the shaking fixtures, and the space hit the ground. Diving to the edge of the cliff, everyone hurriedly escaped from the spacecraft. Yuncai rescued Zhian, who had almost fallen. After everyone got off the ship safely, the spacecraft fell. The second long’s ribs broke and pressed to the lungs, causing breathing difficulties. There are 7.6 kilometers, and Yuncai wants everyone to move quickly. After some rushing, everyone finally saw the Bohai base and saw that there was only 9% of the oxygen left. Yuncai asked everyone to hurry up. However, Ms. Huang couldn’t walk because the bone pierced into the lungs. He suddenly vomited blood and died. Everyone continued to rush. At the end of the day, he finally entered the base.
