She accidentally broke into an interlocking ancient world, each of which was barren, dilapidated, and full of dangers. There is no golden finger around, only infrastructure skills and a tough mind. From diverting water and building roads in deserted villages, to consolidating the defense and security of small border towns, and then to reclaiming wasteland and promoting agriculture in disaster-stricken areas, she used her mortal efforts to dig mountains and canals, pave roads and bridges, build water conservancy projects, and develop production. In strange worlds, she resolved clan conflicts, united scattered people, turned desolation into fertile soil, and gave the homeless a home. Every time she completes a world's infrastructure task, she will start the next unknown journey, and those close friends and companions she meets along the way become the glimmer of light on the way forward, supporting her to travel across mountains and rivers, just to build thousands of lights and human fireworks.
