Traveling Through the Apocalypse, That Cute Girl Is so Cool

[Imaginary doomsday background + alien beasts + system + strong female + cool writing + superpowers + female protagonist who is cute on the outside and A on the inside + no CP, no zombies] Su Yin died while working in a civilized society and traveled to a terrible apocalypse where social classes were reshuffled and the right to speak was in the hands of people with high powers. Su Yin accidentally activated the system. With the support of the system and her character of never giving up, she upgraded step by step. She secretly built her own base in each system mission, moved all the people from the periphery of the base into her own base, and started infrastructure construction! "Wow! What is that? Isn't that a villa area where S-class beasts are stationed all year round? Why is there anyone there?" "Do those people look familiar to you? Are they people from the East and South districts before?" "I thought they were all dead! I didn't expect..." "Look at their food. They even have white flour steamed buns. Are they growing vegetables in the yard?" The heroine is a girl with a soft and cute appearance. She is often misunderstood by people as having a delicate body and is easy to push down. In fact, she can kill Lu Zhishen with one punch and shows no mercy to evildoers. [In the early stage of the full text, there will be a small amount of confrontation between the male and female protagonists, but there is no emotional line. The female protagonist is busy upgrading infrastructure. There will be ambiguity in the later period, but the female protagonist just wants to be alone and beautiful.
