On June 20, 1932, seventeen Yunyin envoys wearing white robes walked into Konoha Ninja Village with their heads raised and their chests raised.

"Welcome, you guys come from afar, why not go and take a rest first?" The third generation of Hokage, who led a group of senior executives, greeted them warmly.

Yun Yin's team leader, who is also the same as the third generation of Lei Ying clan, said softly and politely: "Thank you, thank you, Konoha is still as hospitable as ever!"

"Of course." The third generation of Naruto agreed and led them to Konoha Center, the luxury hotel built last year with the senior management.

There were a group of people talking and laughing on the road, but no one noticed the figure hiding underground.

"It doesn't look like a ninja, but will Yun Yin send ordinary people here?" After analyzing the specific situation, he turned into a ball of white smoke and disappeared underground.

...

At the Uchiha Kendo Hall, Shen, who had just chopped down 50 tribe members, suddenly frowned.

"I came to Konoha in half a month? It seems that Yun Yin and the others are very anxious..."

It spans more than 3,000 kilometers and walks from the Land of Thunder to the Land of Fire. It is not something that ordinary people can bear.

"You don't have to look at it, you know that these people are all ninjas. Yun Yin's group of people should disguise themselves as if they are a little bit..."

He believed that Konoha's senior executives should not be unable to see this abnormality.

"It's time to rest, get up and continue!" Shen pulled out the Tianbuliu sword and prepared to practice until the evening to see the situation.

The fifty Uchiha tribe members who were almost exhausted could only stand up and set up an offensive posture helplessly.

...

It is built with collective investment from various families and is nearly 100 meters high.

After the Yunyin messengers in Room 2046 entered the room, they quickly checked all the furniture decorations inside.

The decoration of the whole room is very simple, with gray and red walls made of a little embellishment, a large-sized TV set inlaid on the wall, four or five sets of black sofas, and a large bar forming a living room layout of nearly 100 square meters.

In addition, there are six three-person rooms, each room with an area and layout that is no less than the living room.

"Captain, there is no abnormality."

"Very good, I can finally take off this damn clothes." After Ji, who was sitting on the sofa, said that, he tore off the white robe on his body.

On hot days, it was also difficult for them to wear this outfit.

"Captain, come and see what this is."

The words of his subordinates made Ji unable to help but look up in the direction he pointed.

"What's this?"

"It seems like a machine that can release air conditioners, it should be the air conditioner mentioned by intelligence." His subordinates said, and pressed the switch of the remote control.

With a "drip", the air conditioner hanging on the wall opened the cover and transported air conditioning into the living room.

Ji immediately felt a chill that rushed straight to his celestial cover: "Comfortable..."

"I didn't expect that Konoha had such high technological strength."

"That's right, they've used this kind of good thing just before we finished the electricity supply in the whole village."

"It seems that the information has not been exaggerated. Konoha is indeed ahead of us Yunyin for nearly ten years."

Ji listened to his subordinates' discussion and began to compare the technology of both sides.

As a future technological power, Yunyin naturally has a lot of high-tech.

But energy has largely restricted their rapid development.

Electricity was first discovered and utilized by Yunyin.

As its name suggests, the Country of Thunder is a country with frequent lightning.

A long time ago, people living here discovered that lightning is an energy that can be used efficiently.

It was just because of the long-term wars in the ninja world that they did not have enough time to find a way to store electricity.

It was not until the end of the First Ninja World War, which had just been established more than ten years ago, that Yunyin Village took advantage of the peacetime to invent the battery used to store electricity.

Being able to store means being able to use, so simple machines such as electric lights and electric fans came into being.

Years of research on electricity have led them to solve the fundamental problem of collecting electricity through wind power generation and thermal power generation in the past few years.

Until now, the entire Yunyin has powered on the entire village, and every household can eat watermelon with a fan in the summer.

But what about Konoha? It will refrigerate for you directly!

The chemistry and physics knowledge involved in this can be studied thoroughly in just over a decade.

"What method is used to refrigerate this air conditioner..." Ji Baisi was puzzled.

The reason why the third generation of Lei Ying let him serve as the captain was not only because he was a scientific researcher.

Konoha’s air conditioner obviously does not use electricity to generate electricity!

First, I didn’t see the big battery of my own, and second, I didn’t see the wires that spread throughout the village. No matter how you look at it, it wouldn’t be converted into heat energy, and then it would continue to refrigerate through material sublimation.

Yun Yin has been able to roughly draw the theory, but it just lacks relevant formulas.

Ji got up and carefully removed the air conditioner from the wall and began to study the specific structure inside.

"Is there an iron block that can continuously refrigerate?" He also found himself unable to crack this thing.

"With the fluctuation of chakra, is it the use of changes in nature to refrigerate?"

As a scientific researcher, Ji, of course, understands whether this matter is difficult or not.

Chakra has five mutual restraint attributes, and it is not difficult to mix in the correct proportions, but the barrier material is a difficult problem.

Both are indispensable!

What should I do if I don’t know the correct proportion? Find the material for the barrier!

What should I do if I can’t find the barrier material? Calculate the correct proportion and look for it!

"Koye's technology is really ten years ahead of us..." Ji could not refute this iron-like fact.

He also believes that Konoha's solution that uses chakra as energy is much more efficient than Yunyin.

According to the ninja cognition in this world, chakra is a kind of energy condensed by the spirit and the body, which can be said to be inexhaustible.

As long as chakra is not excessively extracted from the human body, it is basically equivalent to zero cost.

"No wonder all the Uzumaki clans came here..." Ji Na only understood why Konoha wanted to protect the Uzumaki clan.

Unfortunately, all this was just his imagination.

The current vortex clan does use their own chakra to work and pay off their debts, but it is only a small part.

A human-metal computer has been developing solar and chemical energy for a long time.

It is not a problem for him to preserve the basic theories and related formulas of his previous life and conduct research and development from scratch.

Originally, in his vision, chakra was a biological energy that was to be abandoned.

Not to mention squeezing labor, the core container used to preserve chakra alone is a bit expensive and cannot be widely popularized in the Naruto world.

Use a tailed beast instead? Maybe one day it will be stolen!

In addition, the country of Fire, which is stupid and has a lot of money, can have the financial resources to buy these products with a premium of 20 times, and also make a bold statement that it will be popular all over the country.

A big capitalist laughed out loud on the spot. He felt that when solar and chemical energy were researched, he could go to the Kingdom of Fire to harvest another wave.

Spend the money earned from others for research and development, and then sell the results at a premium. Daming of the Kingdom of Fire is a good person!

"When you go back to Yunyin, you have to carry out the development of chakra as soon as possible..." Ji, who was led by mistake, thought that he had to throw away the electricity and embraced the zero-cost chakra.

Today, Uchiha Shin arrived in outer space safely.
