Falling into an Unknown Galaxy at the Beginning, I Survived by Dismantling Ships

In 2187, humans have colonized many planets in the solar system, but the genius navigator Lin Xiao fell into an unknown galaxy with his ship and people in a deep space accident. The main engine stalled, and the oxygen and water circulation was on the verge of collapse. She could only rely on a "disassembly level" temporary repair to force ignition, but the cost was the permanent loss of key modules. In order to return home, she must crack the return mechanism of the ancient ruins "Gate Network" under the pressure of resource countdown, unknown biological threats and loss of communication in deep space. But what really made her despair was not the journey, but the truth. In an abandoned circular space station, the remains of a decades-old human-standard rescue capsule left behind half an encrypted aeronautical map and a warning: Don't open the door. It turns out that humans have not come here for the first time, but have been screened, recycled, and eliminated time and time again. The gatekeeper AI begins to track in different levels, and the solar system enterprise salvage team disguises itself as a rescue team to approach; every time the ruins technology is used, her "signature" will be exposed, and every battle and exploration must be exchanged for water, fuel, and a way to survive. When talent and rationality are pushed to their limits, can Lin Xiao complete the last jump back before the galaxy-level blockade is completed?
