Survival Game: I Have an Island in the Middle of a Lake

[Female-centric protagonist + no romantic pairing + infrastructure building + farming + adorable pets + female protagonist remains strong throughout and reaches the top in the later stages] While on a scientific expedition in the mountains with their mentor, they suddenly encounter a major global event that pulls them into a survival world. No time to worry about the lost modern life, Jiang Lanyue wrapped herself tightly in her hard-shell windbreaker and decided to start by finding the perfect place to put her shelter. ... I don't know when it started, but a rhyme began circulating in the survival world: In the heart of the continent, in the heart of the Flying Pigeon Federation, lies an island in a lake. It is mysterious and powerful, it is beautiful and abundant. Golden wheat gathered into a sea, and wondrous materials that even the most powerful empires could not gather were piled into mountains. Ancient dragons dwell here, and the light reflected from the goddess's drawn bow rivals that of the moon high in the sky. Even the most ferocious beast tides cannot get close, and the most devastating natural disasters cannot shake it in the slightest. This is an empire and federation that doesn't need city walls. When you see white sails gathering like clouds and horse-drawn carriages winding like a long river in the distance It is then known that all the currents flow towards this island in the middle of the lake. ... Special note: There is a development period, it's not an invincible start; there are good trading partners, but no teammates, Mei Bao is a one-woman army; Mei Bao herself is a laid-back person, not a good person in the traditional sense.
