Lu Zeming plucked an ear of wheat and rubbed away the husk. The Spirit-Gathering Array had ripened it, and though it fell short of Spirit Wheat, it was several times better than ordinary wheat.
The grains were larger, heavier, and more nutritious. Most importantly, they grew in an astonishingly short time.
Lu Zeming did not get carried away. Spirit Energy was ultimately a form of energy. High school biology had taught him that energy diminished as it passed through each level, while matter cycled and could be reused.
Put simply, the Spirit-Gathering Array could supply Spirit Energy, but not the carbon, nitrogen, phosphorus, potassium, magnesium, and other minerals plants needed to grow.
If they kept using the array to ripen crops, the plants would eventually absorb all the minerals in the soil. Then, no matter how abundant the Spirit Energy was, they would stop growing. They would lack the material needed to build their cells.
Fortunately, that problem was easy to solve. With homemade Farmyard Manure and wood ash, the Spirit-Gathering Array could theoretically produce grain without end, as long as there was enough waste to feed it.
Lu Zeming had the wheat harvested, then brought in three large cartloads of fermented Farmyard Manure and wood ash and spread them across the field.
They planted another batch of wheat. A little over ten minutes later, it was ripe.
Lu Zeming repeated the process four or five more times. Only after confirming that it worked did he hand the Spirit-Gathering Array over to Matsumoto Seizo, head of the Agriculture Department.
The old man was so moved that he kept wiping away tears.
"This isn't a Spirit-Gathering Array. It's a treasure trove! With it, the village will never have to worry about going hungry again. And that's not all. We'll have a
