Experiment

The wheat sprout did not spot growing as Abel as observing it. Instead, Abel could even hear the sound of its growth through the power of will.

300 stems of wheat, oats, and barley kept growing. Abel darkly thought to himself, "what have I done!"

After an hour, the growth of the crops slowed down. They were fully formed by that point, and it didn't look like they were going to grow anymore, but Abel felt another explosion incoming through his power of will. Those crops were still gathering energy.

Abel looked over at the other 600 crops. They were still as always. 

It seemed like he had created some kind of special liquid by combining the 3rd goddess fountain water through the Horadric Cube. Although he didn't know what those crops would turn into next, they could grow fast. That was all it mattered.
