Relying on such primitive manual water lifting methods could not possibly support the agricultural scale envisioned for large-scale operations.
And once continuous drought weather struck, a complete crop failure was almost a foregone conclusion.
No, absolutely not.
Agriculture and food were the foundation of medieval society, especially in a territory like his, with limited land and a large population.
A river on his land split into three from the Brightmoon Mountains and flowed through, and his territory was also a large, high-to-low slope, making it the best farming area if water conservancy was developed.
If it weren't for the current crises and large-scale reconstruction in his territory, he would have mobilized his people to build a dam in the Brightmoon Mountains.
Arthur pulled at his warhorse, leading his riders to gallop back to the Lions Den.
While galloping forward, he looked back and ordered, "Brin! Go find a few of the most experienced old farmers! Call them all here! Immediately!"
The Lions Den was just a short distance away, and Arthur, leaving his riders to rein in their horses, dismounted with a leap.
He rushed straight to the study, saw Evelyn sitting at the desk, and his voice carried an undeniable urgency: "Evelyn!!"
"Come here quickly!"
Evelyn put down the ledger in her hand, saw Arthur's serious expression, and immediately stood up and walked over.
He didn't engage in extra pleasantries, nor did he explain to Evelyn what he was going to do, as if afraid his past memories would disappear.
Arthur walked to the huge oak table and quickly unrolled a blank parchment: "Evelyn! Get a pen!"
He stared at the parchment, and the flood of knowledge from another world in his mind began to churn, yet he didn't know how to start writing. His mind was dead, move quickly!
Soon, Brin, who was stout and still had sawdust on his hands, and several dark-skinned, reserved farmers entered the study. Everyone looked at Arthur, who was at a loss for how to begin writing, and showed puzzled expressions.
Arthur slapped the pen on the table and looked at Evelyn: "Evelyn! Get a pen!"
"Draw a huge wheel! Very big!"
Evelyn's quill, saturated with ink, moved quickly across the parchment.
Arthur pondered for a moment, thinking, *It seems... it should be like this, but Westeros probably doesn't have bamboo.*
"Along the edge of the wheel, tie a circle of wooden tubes with hollowed-out interiors. The openings of the tubes should be slanted, like this...."
He gestured an angle in the air with his finger.
"Below the wheel, there must be blades that can be pushed by the water flow."
"Next to the wheel, set up a tall trough, positioned just right to catch the water poured out by those wooden tubes."
Agricultural production in Westeros had not yet developed to the point of chain pumps, so for the people of this world, this was still an incredibly strange structure.
The drawing gradually became clear under Evelyn's pen. Brin and the old farmers gathered around, their faces filled with confusion and incomprehension.
Arthur's finger pointed at the drawing, his voice steady and powerful: "Look here."
He pointed to the blades below the wheel: "We will use the flow of the Little Three-Fork River to make it naturally impact these blades, pushing this huge wheel to rotate."
His finger then moved to the wooden tubes on the wheel's rim:
"As the wheel turns, these wooden tubes will automatically fill with water when they submerge."
"Then, the wheel continues to rotate, carrying the water-filled wooden tubes to the highest point."
He finally pointed to the elevated trough:
"Because the tube openings are slanted, the water will pour out by itself at the highest point, flowing into this trough."
"We only need to build irrigation canals starting from the trough, and we can divert river water to anywhere we want on the hillside!"
Arthur raised his hand and pointed to them: "My land, from the Brightmoon Mountains to the Green Fork River, is a high-to-low terrain!"
"We just need to build multiple such chain pumps on the tributaries! And then dig out water grids! This way, we can spread water sources throughout my territory!"
The study was silent.
