Hey, Am I Not an Ordinary Person?

[Save and collect first, then write later~ Compare your feelings] In the 140th year of the New Era, alien species invaded the earth on a large scale. Six months later, the United Ministry notified all humans to evacuate the West Sector. The West End has fallen, and non-superpowers cannot get involved. Previously, plant species and animal species had occupied the southern and northern zones respectively. Humanity has its last remaining base: the East. * After traveling through time, Xu Yun opened his eyes and did not know that he was in an occupied area. The environment here is harsh, supplies are scarce, desolate, and there are also weird and terrifying alien species... At the critical moment, a voice came out in her mind: [System is activating...] [Repair function has been turned on——] [The search function is turned on——] [The Points Mall has been opened——] Xu Yun: I can survive. The system's points mall has a variety of items, including food, medicine, seeds... Everything. Xu Yun diligently killed alien species, upgraded the system and accumulated points, and finally built his own safe house in the occupied area. The only trouble is that there is a lack of companions to communicate with. So Xu Yun, whose vocal cords almost deteriorated, bought a polar bear in a mall, went out to pick up a small potted plant... And tried to make his new home lively. Although the little creatures I brought home were a bit strange—— Polar bears are tall and powerful, but they do not eat or drink, and prefer to lie down and sleep. The small potted plant is weak and frail, but the mutant vines it grows are as thick as a thigh. The little tit is round and cute, and its hard horny beak can peck a hole in the iron sheet... Xu Yun thought again and again: It's the end of the world, so it shouldn't be surprising if anything happens. Until one day, Xu Yun picked up a walkie-talkie and found the human base in the end of the world. The new friend knew that she used to live in the occupied area, and she was enthusiastic about popularizing a lot of relevant knowledge: For example, Ji Bei, the boss of the animal species, can kill hundreds of alien species at a time. He has a very bad temper and doesn't like humans. The most powerful among the plant species, the Linvine must be punished. The vines can monitor the movements of a city. There is also the boss Ling Que, who has an unstable personality and can attack without distinguishing between friend and foe... Xu Yun: Huh? She looked at the familiar yet unfamiliar figures in the picture, her expression slowly turning petrified. After the new friend introduced these things, he mysteriously told Xu Yun: "According to internal information, these big bosses have been acting strangely recently and meet frequently. It is suspected that reactionaries are united with them to start a new war against mankind." Xu·Reactionary·Yun hesitated: "Probably not..." (Weak) (wiping sweat) These guys were still taunting each other this morning over who would eat the last piece of cake. *With CP *Updated with the list Purpose: Live well
