In the next two days, whenever he had spare time, Xie Jingchen kept studying that transparent thing, confirming it could ignite objects.
He decided to use the telescope lens to burn the grain and grass of Nanliang.
During these two days, he also figured out where the grain and grass were hidden.
However, the weather was against him; when he was ready to act, it started to rain.
But it was also because of the rain that he found his chance to act.
With the heavy rain, no one would think of burning grain and grass; the military was less vigilant, giving him the perfect opportunity to stealthily fix the lens in a spot not easily noticed.
Burning grain and grass was a major achievement, but compared to his undercover work in Nanliang, risking exposure to burn the grain and grass didn't seem worth it.
Now that he had a perfect plan, there was no reason not to proceed.
The heavy rain poured for one day and drizzled for another half day, until it cleared up in the evening.
