As their team and others were planting trees in the new area, the sky suddenly darkened and this time, in many areas near their homes, several different types of viruses appeared. When they see the situation, they tell their people to hurry back to the pit and take the elevator to their office to change clothes . So hurry up to complete the mission. Upon arriving at the scene, the SQ and UQ siblings used their guns to kill the virus, with the KQ and MQ watching a strange black ball hovering in the air and there was lightning around of its which made them unable to catch the strange ball. KQ told SQ and UQ to fight the virus in the background, both flying through the air to find the source of the strange bullet falling behind. As they flew into the cloud, the source of the bullet drop, an incredible thing happened. Because there is a strange tree that floats on the cloud and drops its fruits. As they fly closer to the strange tree, they see deer that look like sleeping plants. He seemed to notice that someone was staring at him, so he opened his eyes and walked over to them and made a very cute gesture like a dog or a cat. The plant energy of this deer that attracts the virus from the original litter to destroy it. But the fallen bullet is the protective shield of this strange creature. When they turned back to the strange tree, the shadow vanished, leaving only the deer creature . When they came down, they saw the virus attacking them even more, forcing the four of them to join forces. But no matter how hard they try to fight, protect and kill the virus, they still cannot fight the virus and are seriously injured. Suddenly, the deer creature sent a signal from its body, causing the virus to fire from the lightning, and the bullet gathered into a large ball that was about to explode. The deer creature motioned for them to hurry up and hide in their pit. When they returned to their positions with the deer creature, the bullet exploded, burning trash on land and all over the territory of their ancient homeland. And disperse natural gases to dissolve chemical fumes that burn trash and rain down to clean up the area. When the sky stopped raining, their team and the people came out, seeing that the sky was starting to clear, that there was more and more oxygen, that a beautiful rainbow was emerging and that the empty earth grew like plants that a new one grows again, they were so happy, and people think of this strange deer creature as their angel, and a new history of mankind is written in new pages. Ten years later, KQ and MQ had a son and a daughter, while UQ and SQ married a member of the village and gave birth to a daughter. A strange deer creature named Sasha also grew up and always produced bullets to drop them off in other areas after killing the virus, which caused people to start migrating to another area, to reorganize into new cities and civilizations. Their new religion, without following the old path, destroys the environment for generations and lives in happiness and peace.
