A hundred miles from the battlefield
"Lulie, Xiūsang, come quickly! I've got news about Lord Romon!" Inside a heavily fortified manor, two young men were practicing combat techniques when a knightly-looking man suddenly entered from outside, carrying a large sheet of paper in his hand.
The two young men immediately looked up at the knight. "Captain Tekaxiu, you have news about our lord?"
"Yes. I was inspecting the territory just now and chatted with the captain of a merchant caravan. It turned out they had come from the Aisk Kingdom! That's where our lord's home is!" Tekaxiu said excitedly. "I asked around and found that our lord is quite famous now. Everyone knows something about him, so I wrote it all down."
"Come, let me see!"
"I want to see too! What news is there about our lord?" At those words, the two young men immediately put away their weapons and ran over.
"Look, it's all written here—so much news about our lord..." Tekaxiu proudly showed the sheet of paper to the two of them.
Lulie leaned closer and read aloud, "...Fifteenth-Level Druid... Biogas... Ecological Farmland..."
The paper recorded quite a few things, but those were the only key words Lulie could understand. Most of the rest described the construction methods for something called biogas.
"Tekaxiu, what is this biogas?" Lulie raised his head and asked in great confusion.
Xiūsang also looked at Tekaxiu curiously. He was not as straightforward as Lulie and usually spoke very little, but that curious expression alone said enough.
Tekaxiu chuckled and explained excitedly, "You don't know this—biogas was created by our lord. I heard that once you build it, you don't need to chop firewood for cooking anymore, and it can even enrich the soil... Do you know what keeps biogas running?"
"No." How
