People are in Konoha, controlling twelve spells

After solving Kado, Naruto summoned Dazna.

"Kado is dead. From today onwards, no one will stop you from building a cross-sea bridge."

When Dazna heard this, he was pleasantly surprised and said, "Thank you, Naruto-sama!"

Defeating Kado is the long-cherished wish of many citizens of the Land of Waves, so Dazna's voice is sincere.

"How are you going to build this sea-crossing bridge?" Naruto asked.

Dazna took out a roll of blueprints from the backpack he was carrying, and handed it to Naruto respectfully.

"I drew the blueprint for this sea-crossing bridge a long time ago, and now I just need to take out the previous design." Dazner said.

Naruto looked at the drawings and shook his head: "Although your design is good, it lacks a vision for the future."

Prospective to the future?Dazna was puzzled and asked what this meant.

Naruto didn't answer him, but instead asked, "Have you heard of trains?"

Dazna thought carefully for a long time before replying: "I have heard people say that in the far north, there is a country called Snow Country, where there is a kind of steam-propelled iron car, which seems to be called a train."

"Master Naruto, is that what you said?"

(Train, appeared in Hokage's first theatrical version of "Big Live Drama! Yukihime Ninfa Tie")

Naruto nodded, indicating that he was correct.

"Since we want to build a bridge, it is better to build a bridge across the sea that uses both road and rail. The upper part is reserved for carriages and pedestrians, and the lower part is paved with rails for trains to run."

The country of waves is an island country with a natural deep-water port.

If you go by sea from the country of waves, you can reach the country of soup, the country of the moon and the country of thunder to the north; the country of water to the east; the country of tea and the country of the rainbow to the south.

It can be said that the Land of Waves has the attributes of a natural trading port.

If a railway can be built, the goods can be transported from the countries on the mainland to the country of Bo, and shipped by sea from the port, and can be distributed to many countries.

Especially the country of thunder and the country of water, the two big countries.

This is also the reason why Cardo came to the country of Waves to engage in the shipping industry.

"However, if we want to build such a dual-purpose sea-crossing bridge, the cost of building the bridge will probably increase significantly." Dazner hesitated.

It's not that he can't see the goodness of Naruto's plan, but it's just that the land of waves probably doesn't have enough money to build bridges.

"It doesn't matter, I can pay for the bridge building in advance." Naruto said generously.

Dazna's eyes lit up: "Really? It takes a lot of money to build a bridge!"

"It doesn't matter. As long as the bridge is completed, the management rights of the bridge and all rights to the land within 99 kilometers along the railway line will be transferred to me. The time is [-] years."

"All the profits generated during this period will be handed over to me. How about this plan?" Naruto asked with a smile.

Although he is a ninja, he has enough strength to guarantee him any rights he wants.But to be able to obtain this right legally and compliantly, Naruto does not have to use force.

Dazna nodded: "Of course, this is what Naruto-sama deserves."

When Dazna left Naruto's residence with gratitude, he heard a 'bang' and a burst of white smoke.

It wasn't Naruto's real body that Dazna was talking to just now, but the avatar he created using the "Multiple Image Avatar Technique".

At this moment, his true self is in an open space in the forest, practicing ninjutsu learned from the "Book of Seals".

Incidentally, Sasuke is also practicing these ninjutsu.

Seeing the gap between him and Naruto, he practiced harder and harder.Apart from eating, drinking and sleeping every day, the rest of the time is devoted to practice.

"Sasuke, you don't need to pursue the number of shadow clones." Naruto pointed out after watching Sasuke's training.

"It's because of my special circumstances that Chakra can create so many clones."

"According to your situation, it is completely enough to create more than 100 shadow clones by the technique of multiple shadow clones, and there is no need to pursue more numbers."

Naruto taught Sasuke three ninjutsu in total, namely the sealing technique "Four Elephant Seal", the A-level ninjutsu "Multiple Shadow Clone Jutsu", and the A-level ninjutsu "Mutual Riding Detonation Talisman".

The first sealing technique, because there is no opponent to seal, it is difficult to practice.

The third ninjutsu, Mutual Explosive Talisman, is powerful, but it has a fatal flaw, which is that it consumes money.

The essence of this technique lies in the unlimited psychic detonation talisman. It will never stop until the enemy is blown to death. Every time it is practiced, it will cost a lot of money.

So Sasuke's focus is of course on the technique of multiple shadow clones.

As for Naruto himself, he is pondering and researching how to improve Spiral Pill.

"Injecting Chakra of other attributes into the spiral pill is a way of thinking. But what if I change the direction of the spiral pill?"

Naruto thought so.

The running direction of the spiral pill is from the inside to the outside, which looks like a repulsive force. Once it hits the human body, it will knock the person away at the lightest.

Naruto, on the other hand, wanted to change the running direction of the spiral pill from the inside to the outside, similar to suction, just like the great whirlpool that can swallow everything in rivers, lakes and seas.

Naruto stretched out his right hand, and a spiral pill in the opposite direction appeared in the center of his palm.

As Naruto continued to inject chakra into it, the spiral pill in the opposite direction not only did not grow larger, but continued to shrink, and finally turned into a very solid black ball.

Naruto let go of his hand, and the small black ball immediately fell to the ground.

The moment it touched the ground, the small black ball completely released its power, directly blasting a huge deep hole in the ground!

With a thought, Naruto's figure appeared in the distance, on the edge of that huge pit.

"This power is really terrifying!"

The ground under his feet disappeared completely, replaced by a deep crater, as if a super bomb had exploded there.

Naruto was sure that if his power storage time was longer, this spiral pill in the opposite direction might be able to blast the entire Konoha Village to the ground.

"It is no longer a spiral pill." Naruto finally gave this ninjutsu a new name, called the "spiral wheel Yu" technique.

In the next few days, Naruto has been busy developing and perfecting this "Spiral Lunyu" technique, while supervising Sasuke's practice, giving pointers from time to time.

Days like this did not stop until Dazna came to inform that the first sea-crossing bridge in the Kingdom of Waves had officially started.

As soon as the bridge project started, it encountered the problem of insufficient manpower.

For this problem, Naruto's solution is very simple and rude.

That is to spend a lot of money to recruit people.

A village in the Land of Waves.

"Have you heard? The bridge project is recruiting workers, 300 taels a day per person!" A man said in a grocery store at the head of the village.

"What, are you kidding, the salary is so high?" Someone replied.

The country of Waves is a poor island country, and 300 taels a day is a great price for them.

"Why am I lying to you!" The man before was a little anxious: "This is the news from my third uncle who lives in the town! It is said that there is still a meal?"

"There is still wages for the meal package?! The bridge builder is still recruiting."

"If you want to recruit people, I will go too!"

..........................................

Within a few days, hundreds of workers poured into the construction site of the bridge, and the construction of the bridge officially started.
