Nature was a loop, and the world was a grand cycle. Thus, merely improving soil quality would likely not be enough. They also had to address the water and the air. If they did not alter everything within the cycle, the improved soil would eventually be contaminated by the rain.

Huo Wei had already continued his research. The survival rate of the corn seedlings in the experimental fields was decent, but it paled in comparison to the sweet potatoes produced by the Door Spirit Mall. Sweet potatoes naturally had looser requirements for their growing environment. Since Chun Mian had provided premium goods from the Door Spirit Mall, their vitality was inevitably higher. As a result, the sweet potatoes flourished far better than the corn. After observing the thriving sweet potatoes, the villagers finally felt a renewed sense of hope for the future.
