In 2749, human civilization has long since left the solar system, but it has fallen into a dilemma more cruel than interstellar navigation - the depletion of water sources. The blue planet that once nourished all things has become an abandoned land with barren resources. Humanity is scattered on colonial planets on the edge of the galaxy. Every planet with drinkable liquid water has become a battlefield for all forces. Morning Star, a desolate planet labeled as a "potential water star" by the Interstellar Alliance, has become the focus of a new round of resource competition due to the detection of liquid water veins buried deep underground. And Li Luo is the most special guardian in this dispute.
