I Cultivate with String Theory

The universe is not the product of natural evolution. It is a system of designed "cultivation vats."

The Weavers of the Dao from the previous String Epoch discovered that "higher-dimensional harvesters" lurked in the depths of the String Sea, feeding on energy released by the decay of the vacuum. The harvesters cannot enter individual universes directly. Instead, they "design" them as metastable cultivation vats, allowing civilizations to evolve within them until the appointed time, when they harvest the string-vibration energy of the entire civilization.
