Weird Invasion, I Pick up Trash and Evolve

Bai Yujing lost an arm due to an accident, but she was lucky enough to pick up a very affordable robotic arm. Although it was just the lowest-grade robotic arm, she was still very happy. Unfortunately, within two days of installation, the world mutated. The weird phantom has become a reality, the overlapping area has become the scene of a severe disaster, and countless absurd and unspeakable monsters are wandering in the city, harvesting lives. Bai Yujing was busy escaping like everyone else. She thought she was just an ordinary person until the left hand of the robotic arm suddenly changed its shape and penetrated a monster. Bai Yujing watched as the mechanical left hand took out a scarlet crystal stone from the monster's body, and then expertly embedded the crystal stone in it: "..." Pupil earthquake. Bai Yujing's calm expression broke, staring at the mechanical arm's silent collapse. She knows that cheap goods are not good ones! ! ! ＊＊＊ I don't know when, the world has quietly changed, and weird overlapping areas have begun to appear in various places. In the overlapping areas, you can see blurry and full of weird shadows. Other than that, there is no danger. People lived in panic and gradually got used to it, until one day, someone passed by the shadow but did not pass through it... The overlapping area has become a hell, but it is also an important resource place. People have discovered that the crystals obtained after killing weirdos in the overlapping area can awaken incredible abilities. As a result, the overlapping area has become a hot spot again, and people continue to enter the overlapping area, looking for opportunities to reach the sky in one step. However, everyone found that every time they went to an overlapping area, they would always meet a woman rummaging through the trash. Everyone thought she was out of her mind, leaving aside good crystals and picking up a pile of scrap metal. However, when the overlapping area appeared on a large scale for the second time, and the strangeness invaded human territory with an overwhelming force, a woman picking up garbage suddenly appeared. Her whole body was covered in dense steel, and with a single wave of her hand, she could be fired upon by thousands of beams of artillery fire. She could fly to the sky and escape from the ground, and was omnipotent. The terrifying and strange things were powerless to resist under her hands! Everyone: ... Isn't this a bit too scientific! ! ! Bai Yujing: ... Who says it's not? But - it smells so good! Motto: All roads lead to Rome!
