The stable operation of the East Sea Bay Oasis and the booming commencement of the Southwest Peninsula development acted like two shots of adrenaline, thoroughly activating the long-dormant potential of Sunagakure.
However, with the exponential growth of the reclaimed area, a grim reality presented itself: traditional human and animal labor could no longer meet such large-scale, high-efficiency production demands.
All eyes turned once again to the Sunagakure Joint Research and Development Department, specifically to that Minister who constantly created miracles—Sayo.
After successfully mass-producing a sufficient quantity of "Ecological Puppet - Seawater Purifier" and ensuring their stable operation, Sayo did not stop.
His vision had long been cast toward a broader horizon.
How to apply Ninjutsu and Puppet Technique more deeply into production and construction, and comprehensively improve efficiency, became the new core topic for the Research and Development Department.
Consequently, under Sayo's personal leadership, the elites of the Research and Development Department once again threw themselves into intense research.
Based on the mature Natural Energy Core power supply System of the "Ecological Puppet," the precise Sealing Technique control System, and high-strength alloy forging technology, a series of behemoths born for production and construction gradually turned from blueprints into reality in the research workshop.
The first to be unveiled was the "Giant Plow" series of large-scale farming Puppets.
These Puppets had a sturdy and heavy design, with a wide tracked structure on the lower half, allowing them to easily traverse soft sandy ground or newly reclaimed fields without ever sinking.
Their core component was not a combat weapon, but a huge, cold-gleaming composite plow blade, along with automatic seeding and soil-covering units at the rear.
Powered by the stable energy provided by the purifiers, they possessed strength far exceeding dozens of strong oxen, capable of plowing and precisely seeding the land day and night at an astonishing speed, with efficiency over a hundred times that of human labor.
When several "Giant Plow" Puppets worked simultaneously in the vast fields, the scene was spectacular; the earth was turned over like waves behind them, nurturing new life.
Following this, the "Pack Beast" series of large-scale transport Puppets was developed.
The sea salt and grain produced in the Southwest Peninsula needed to be transported back to the Village, and supplies from the Village needed to be sent to the development front lines.
Traditional camel caravans had limited carrying capacity, were slow, and were vulnerable to attacks.
The "Pack Beast" Puppets perfectly solved this problem.
They possessed huge storage compartments, had immense load-bearing capacity, and adopted a hybrid chassis of magnetic levitation and tracks, allowing them to adapt to desert terrain while maintaining decent speed.
They traveled in convoys along fixed, classified routes like a moving Great Wall, forming a brand-new material artery for Sunagakure.
Finally, to meet the construction needs of the Southwest Peninsula ports and infrastructure, the "Rikishi" series of infrastructure Puppets came into being.
These Puppets were true steel giants, with body sizes even approaching the combat Puppet "Gundam," but with a more robust structure and even more terrifying strength.
Their arms could be retrofitted with massive cranes, pile drivers, excavators, and other engineering tools, allowing them to easily move tons of boulders, drive sturdy Foundations, and dig large trenches.
After Earth Release Ninja completed the macro-level terrain transformation, these "Rikishi" Puppets were responsible for precise, high-efficiency, refined construction; ports, warehouses, roads, and other facilities rose from the ground at a speed visible to the naked eye in their hands.
The advent of this series of engineering Puppets completely changed the production mode of Sunagakure.
Farming efficiency was greatly improved, and vast fields were fully utilized.
Material circulation speed increased, costs were lowered, and losses were reduced.
Infrastructure construction progressed by leaps and bounds, and the embryonic form of the Southwest Peninsula trade hub quickly took shape.
Sunagakure's development thus entered a brand-new stage—the era of mechanized, large-scale production.
The physical strength of the Ninja was greatly liberated, allowing them to devote more effort to patrolling, defense, technical guidance, and more complex tasks.
Sayo stood on the observation deck of the Research and Development Department, watching another "Rikishi" Puppet being assembled in the workshop below, his eyes filled with gratification.
These cold steel creations might not have the dazzling power of combat Puppets, but with every plow, every transport, and every pile driven, they were tangibly changing the face of the Land of Wind and solidifying the Foundation for Sunagakure to move toward prosperity.
The combination of knowledge, Ninjutsu, and Puppet Technique was ultimately not for destruction, but for creation.
This series of engineering Puppets was the most perfect embodiment of this philosophy.
They were the true "strategic weapons" of Sunagakure, the keys to future peace and prosperity.
