"Fourth Brother, rubber trees can produce rubber."
Prince Chu saw Zhao Yao talking about rubber trees with a radiant face and grew even more puzzled, "What exactly is this rubber?"
"Fourth Brother, I'm telling you, rubber is a treasure. It can be used in so many ways. I can't explain it clearly now, but once I get it out, you'll understand." Zhao Yao wasn't trying to be secretive; he genuinely didn't know how to explain what rubber was to Prince Chu, especially since he hadn't seen it himself. "All I can say is that once I get the rubber out, I can make many things that will benefit the people and be good for the Great Zhou."
"Is rubber really that amazing?"
Zhao Yao nodded vigorously, "It's incredibly amazing. Once I make it, you'll know."
Prince Chu trusted Zhao Yao's ability to get things done, and hearing him speak so confidently made him look forward to it.
"What else?"
Zhao Yao asked back, "Fourth Brother, do you know what the greatest resource in Lingnan is?"
