Two weeks later.
Yuzuru didn't know what he had gone through; all he knew was that his body was extremely depleted.
Even though he had experience dealing with Kaguya many times, faced with the stark difference in their physical strength and the desires accumulated over a thousand years, the once powerful him was like a lone boat, easily overturned and capsized by various giant waves, falling into the sea.
Fortunately, Kaguya still had feelings for him, and she always managed to precisely control the degree of her desire, always just draining him dry before comforting him with a heart even more generous than Tsunade's.
All I can say is that it's a bittersweet experience.
After resting for two days in Kaguya's arms, Yuzuru finally returned to the Shinobi World.
That evening, Tsunade and the others watched Yuzuru devour his food and couldn't help but complain, "That woman really didn't leave us anything."
"After all, it's a desire that has accumulated over thousands of years; how could it possibly subside so quickly?"
"It's alright, Yuzuru has a strong recovery ability. After eating and drinking well and getting a good night's sleep, she'll be back to normal by tomorrow night."
Two weeks later, the Kage of the Fourth Village and his guards arrived in the Land of Water in a menacing manner.
It's clear they're working together to exert pressure.
Yuzuru and Mei Terumi were already prepared. One of them was still playing the role of Mr. Arashi, and the other was wearing a straw hat symbolizing the Mizukage. They came to the Land of Water to greet everyone.
"Welcome to the Land of Water, four Kage."
Mei Terumi looked at everyone and said.
" Mizukage, we know that Kirigakure and the Land of Water have already cooperated with the Sea Region Academy. Could you show us?"
"That's exactly what I was thinking. However, Mr. Lan seemed very interested after hearing about this, so he came to invite us to attend a technology sharing conference."
"Oh?"
Upon hearing this, everyone's attention immediately shifted away.
After all, compared to the Land of Water and the Kirigakure, the Sea Region Academy was more of a concern for them.
This mysterious Academy possesses a level of technology far exceeding theirs, and the mysterious Mr. Lan's strength is even more unfathomable.
"Gentlemen, please follow me."
Yuzuru opened the Yomotsu Hirasaka and invited everyone inside.
The group exchanged glances, seemingly wary.
Seeing this, Mei Terumi smiled slightly and went inside first.
Only after seeing this scene did they agree to enter.
After passing through Yomotsu Hirasaka, the group arrived at a beautiful island.
The island is small, with the main building being the central tower, surrounded by wide concrete roads where transport vehicles travel. There is also a testing ground where some unfamiliar devices are being tested.
Those who witnessed this scene for the first time immediately signaled to the guards beside them to record it.
"You flatter me. These are all devices still in the testing phase. There are new monitoring equipment, new vehicles, and energy devices. They will be officially put into use after they pass safety and stability tests."
Yuzuru gave everyone a brief introduction.
" The Sea Region Academy truly lives up to its reputation."
Hiruzen Sarutobi immediately praised him.
"One of the Academy's missions is to change the world through technology. We believe that people in the future will become happier with the help of technology."
Yuzuru nodded, without being overly modest.
"I believe that under your leadership, the Sea Region Academy will definitely succeed."
"No, no, no, you've got it wrong. I'm just one of the guardians of the Sea Region Academy. The direction and future of the Academy are determined under the guidance of the principal; I don't participate."
Yuzuru said with a smile.
"One!"
Upon hearing this, the expressions of the several figures did not change much, but their apprehension towards the Sea Region Academy rose to a new level.
"Is there more than one strong person like him? The Sea Region Academy is incredibly powerful."
"Let's go inside first. The Academy hopes to establish some business collaborations with everyone."
"Business cooperation?"
Hearing this, they became interested and followed Mei Terumi into the building.
Soon, everyone took their seats, and Yuzuru took out several discarded items she had prepared and began to introduce them to everyone.
It has to be said that these country bumpkins in the Shinobi World are really easy to fool. Just a little demonstration of these outdated products made them eager to try them out.
"Mr. Lan, does the Academy sell all these items?"
"Of course, after all, the Academy needs money too. The students' accommodation, food, and the various technological products they consume every year mean the Academy is always losing money, all so that the students can learn as much as possible. Therefore, there always needs to be some special business."
"I see. So, during this period of time, the Land of Water and the Academy must have reached quite a few business collaborations, right?"
"That's true. However, the Land of Water's geographical location is unfavorable, with a humid climate year-round, causing many products to rust faster. Therefore, the daimyo of the Daimyo of the Land of Water has spent a lot of money purchasing products from the Academy to maintain the security of the Land of Water's infrastructure."
"Oh? Could you please tell us a bit? We'd also like to take a look at those products; perhaps we can even reach a cooperation agreement with the Academy."
"Sure."
Yuzuru changed the PowerPoint presentation and directly showcased the new streetlights, as well as many public facilities, including vehicles, large agricultural implements, and some electronic devices.
At the end of the scene, Yuzuru deliberately displays Scientific Ninja Tool.
As expected, this group showed little interest in the earlier ones, but immediately became serious when they saw the last one.
"Mr. Lan, is that a new type of Scientific Ninja Tool in the last scene?"
Ai asked impatiently.
The others also kept a close eye on Lan.
Yuzuru had no intention of hiding this from him.
"That's right. It's Second-Generation Scientific Ninja Tool, capable of using some simple Kekkei Genkai Ninjutsu, such as Lava Release, Boil Release, Lava Release, and Storm Release."
Upon hearing this, everyone's eyes lit up.
"So that means the Mizukage has already bought quite a few of these new Scientific Ninja Tool, right?"
Rasa looked at the smile on Mei Terumi's face and said.
Upon hearing this, everyone's expressions immediately turned grim.
Mei Terumi didn't seem to care, casually trimming her precious nails.
" His Mizukage did indeed purchase fifty sets of Second-Generation Scientific Ninja Tool for national protection. They pose no threat to you all, so please rest assured."
Yuzuru said that on purpose, to make these idiots feel uneasy.
After all, they had already seen Scientific Ninja Tool before. Although they were the worst, the fact that they could unconditionally unleash Ninjutsu as long as Chakra was injected into them was enough to attract their attention.
That's a way to directly transform regular Ninjutsu into hand seal-free Ninjutsu. In battle, the effect of such suddenly released Ninjutsu is extraordinary.
This alone was already quite remarkable, but now, the new Second-Generation Scientific Ninja Tool can actually use the power of Kekkei Genkai, which forces them to pay attention again.
The Kekkei Genkai Ninjutsu without a Seal brings about a qualitative change. To put it bluntly, an ordinary Chunin, with this, can hold off even a Jonin for a while.
But if someone is already Jonin, adding this thing on top of that makes it much more than just 1+1=2. Jonin have top-tier combat experience and can seize every opportunity in battle.
If combined with this blood-stained Ninjutsu without hand seals, it would be absolutely overwhelming for Jonin who lack Scientific Ninja Tool.
