Naruto: Starting as the Third Hokage with Tears in His Eyes

"That's a chakra-conducting lighting system, improved by the Second Hokage and Tsunade from the medical department. It can illuminate the entire main road as if it were daytime at night, greatly improving the efficiency and safety of material transportation and troop movements."

Uchiha Kagami sat opposite A and explained gently; his voice always had a calming power.

Tsuchishiro added softly from the side, "Lord Raikage, according to our statistics, since this road and lighting system were built, the number of accidental injuries and deaths in our village caused by nighttime travel has decreased by 90%. The frequency of caravan travel has tripled."

Data is cold, but it is also the most irrefutable.

The rear half of the carriage presents a completely different scene.

"Kakashi, look at that! That mountain looks like it was split in two!"

Obito pointed out the window and shouted.

Kakashi didn't even lift his eyelids, turned a page of the book in his hand, and replied indifferently, "Those are probably traces left by construction blasting, for road repairs. Can you be quiet for once, like a genin leaving the village for the first time?"

"I call that having an exploratory spirit!"

Obito retorted defiantly, "You're just too boring! Right, Rin?"

Rin Nohara smiled helplessly and handed Obito a bottle of water: "Alright, alright, have some water. Don't disturb the Hokage."

Hiruzen Sarutobi's eldest son, Shinnosuke, the captain of the Dark Guard, was holding his short sword, leaning against the window with his eyes closed, seemingly oblivious to everything around him.

But if you look closely, you can see that his ears are twitching slightly, taking in every sound around him without missing a single detail.

In this strange atmosphere, Lu Xingzhou passed through a narrow canyon, and a magnificent view suddenly burst into everyone's eyes.

It was a colossal gray wall stretching between heaven and earth.

It is like a man-made mountain range, forcefully cutting off a huge, roaring river in half.

Sunlight shines on its smooth, mirror-like surface, reflecting a cold and solid luster.

Below the giant wall, the tamed river water has formed a vast lake, its surface calm and shimmering.

On the other side of the giant wall, several thick water jets gushed out from the reserved flood discharge outlets, making a deafening roar as they crashed into the riverbed below, stirring up a cloud of water mist.

"boom--"

A rainbow rose from the mist and stretched across the canyon.

Everyone present, except for the high-ranking members of the Hidden Mist Village who already knew about it, held their breath.

Obito and Asuma stared wide-eyed, speechless for a long time.

The book slipped from Kakashi's hand and fell to the ground. For the first time, pure shock appeared in his eyes, which always carried a hint of laziness.

"This...this is..."

"Yunlei Dam".

Danzo's voice rang out at the right moment. He stood at the front of the car, arms outstretched as if to embrace his masterpiece. "So far in my career, this is one of my more satisfying works."

His face no longer held its usual gloom, but instead shone with an almost fanatical radiance.

It wasn't the satisfaction that comes from power, but a passion unique to the creator, bordering on romantic.

After getting off the bus and standing on the viewing platform at the top of the dam, everyone felt even more insignificant.

The concrete beneath our feet was thick and solid, and the gale howled through the canyon, making our robes flutter.

"The main structure of the dam is entirely constructed using high-grade chakra concrete."

Danzo, like a tour guide, spoke in a voice that drowned out the sounds of the wind and water: "It can not only completely solve the flood disaster that has plagued the lower reaches of the Land of Lightning for a century, but also provide a stable source of agricultural irrigation water for the land."

He paused, pointed inside the dam, and raised his voice: "But that's just its most basic function. The real core is inside."

He led the group into the inner passageway of the mansion. The passageway was spacious and bright, and the walls were also inlaid with luminous crystals.

A faint smell of ozone and a strange hum of energy filled the air.

After walking for about a few minutes, a huge underground space appeared before them.

Dozens of massive, house-sized metal turbine units were neatly arranged, connected by countless thick cables that resembled giant pythons, eventually converging into rows of complex control panels on the wall.

The river water blocked by the dam flows through giant pipes, impacting the turbine blades with terrifying pressure and driving them to rotate at high speed.

"The chakra turbine series generator set designed by the Second Hokage was manufactured and improved by Orochimaru's Team Zero."

Danzo's voice was filled with awe. "The high-pressure water flow drives the turbine, which in turn drives the built-in chakra conversion core, converting kinetic energy into the purest lightning-attribute chakra, which is then transmitted out through the energy tower. The electricity generated here can not only supply the lighting and production needs of all the towns in the Land of Lightning, but there is even a surplus, which can be transmitted back to Konoha's energy network through the undersea cables we have laid."

You need to use your brain, wait a minute!

Lei Yingai's mind went completely blank.

Where should it be sent back?

He looked at the roaring steel behemoths and the rows of flashing indicator lights on the control panel, feeling that his understanding of power over the past few decades had been completely overturned and crushed at this moment.

This is the power to tame rivers and change the world.

"Of course, design and materials alone are not enough to support such a massive project."

Uchiha Kagami added with a timely smile, "Every cubic meter of concrete poured for the dam incorporates miniature defensive jutsu patterns carved by members of our Uchiha clan, strong enough to withstand the direct impact of most ninjutsu. At every stage of the project, members of the Hyuga clan used their Byakugan to conduct a 360-degree structural inspection, ensuring there were absolutely no flaws inside. It can be said that this dam represents the pinnacle of Konoha's current technology."

"Has Konoha... really come to this?"

Toshiro muttered to himself, his single eye filled with complex emotions: amazement, awe, and above all, a sense of desolation at being abandoned by the times.

"Lord Hokage."

His voice was hoarse, yet exceptionally clear, "Kumogakure... hopes to deepen military cooperation with Konoha. I think... I should send the village's most elite ninjas to Konoha to learn... learn this kind of construction ninjutsu."

He finally understood.

No matter how thoroughly something is destroyed, it's just ruins. But creation, even if it's just a single brick or tile, can build a tower that leads to the future.

This, perhaps, is true strength.

"Oh?"
