"You still know that you've been back, and it's been almost a month since you lost the news in a flash. Where have you been?"

"I went to villages in various countries to help with the autumn harvest."

“…what?”

In the Naruto office, Tsunade obviously refused to believe that Mingchao was going to help with the autumn harvest. Seeing Mingchao's eyes twitched straight, he clenched his fists.

Ming Chao smiled and said, "Mr. Tsunade seems to be a little irritable. What's wrong? I'm really going to help with autumn harvest and experience life."

Tsunade frowned and snorted, "Experience life? The left minister of the Fire Kingdom has lived in the village for almost half a month, and I am so annoyed!"

After a pause, she said again: "I can't beat or scold that old guy, and I have to look at his bad face every day. I originally wanted to find you, the 'Flying Cao Ninzu Rebellion Ninzu, who does not belong to Konoha, and scare him. You have no news yet..."

"Sir Naruto, I don't mind making some pranks to disgust him, but are you sure this is appropriate?" Ming Chao said.

Tsunade was silent, and her momentum was extinguished.

She just enjoyed her mouth and supported the establishment of Wano Country. As a Hokage, she is worthy of Daemon. Thanks to her granddaughter of the first Hokage, she is so popular that she can't be able to be popular anymore. She is also the best doctor in the ninja world.

If someone else is gone, even if Kiki is ready and cannot be changed, the example of Iwa Hidden Village is that Daming cannot force Konoha to start a war, but it is still possible that a Naruto can do it.

Don’t underestimate the country’s tyranny overpower.

After nearly a month of agricultural research, Ming Chao has learned more clearly about this. A group of ninjas who do not know how to use ninjutsu to transform the environment and only know how to fight are pinned to death by daimyos in terms of economics, and there is no doubt about subordinate relationships.

"Forget it, keep dragging him." Tsunade said: "Anyway, I will leave for Wano Country in another week, and let Jiraiya stay to deal with him at that time... I just hope that Nagato will not cause any major troubles, and the Six Kage will talk about it, which has not been mentioned before he went to Iwa Hidden Village."

"I'll go too, I'll leave in a few days. I'll probably get earlier than you. I'll go to Cao Ninja Village first to see how it's going." Mingchao said.

"You?" Tsunade was surprised: "Didn't you sneaked to Kushin Village during this period?"

"Why am I lying to you for this? I'm really going to help Qiuhuo." Mingchao smiled, and then changed the topic before Tsunade took the initiative to ask more details and said, "Sir Tsunade, how is Itachi?"

Tsunade frowned slightly again.

"It's okay for a short time, but it's best not to use those Sharingans in recent years."

After the battle in Yunyin Village, Itachi coughed up blood on the way back. At that time, Ming Chao carefully checked his body for him, and the result was only physical fatigue and excessive consumption.

After returning to Konoha, after being mentioned by Mingchao, Tsunade carefully checked Itachi in the hospital and found some troublesome problems.

Congenital cardiopulmonary dysfunction.

It can also be said to be a genius disease. His heart and lungs cannot keep up with the improvement of his strength and are oppressed by the body. Especially after using the Maneidoscope Sharingan, the body is weak and the damage will be even more serious.

This is similar to Kummaro's blood disease, but it is not that serious.

After Ming Chao's reminder, based on Tsunade's experience, he diagnosed a disease that had no concept of Naruto's world: worry and illness.

Or mild depression.

He put too much pressure on himself. Whether he was killing some of his tribe members for the family and the ninja village, or trying to reintegrate Uchiha into Konoha again, he always cared the responsibility, kept it tacitly and kept everything in his heart.

In fact, it’s okay now. Some treatments are replaced by Uchiha Itachi who killed his parents by extermination. The depression he suffered from may be severe.

"That child Uchiha Itachi..." Tsunade sighed again: "It's obviously the same age as you, and you've experienced a lot of things, why do you look heartless all day long?"

"So you see, there are friends like Shimizu and others, the cute little Kasumi, and the most important thing is to have the beloved Lord Tsunade, you, I..."

Tsunade suddenly got goosebumps and cursed in anger: "Okay, get out!"

"learn!"

Ming Chao left smoothly and reported to Tsunade. He did not go home, but instead went to Konoha's largest electrical appliance shop.

This place is the most similar to a modern shopping mall, full of various electric fans, refrigerators, ovens and other household appliances. At first glance, it looks out of place with the Ninja World and is very strange.

This is not the first time Mingchao has been here. When he first arrived at Konoha, he brought the "Cast Ninja Village activity funds" provided by tourists and bought a complete set of electrical appliances. The shop owner still remembered him and greeted him in person.

Being handsome is always beneficial.

"No, no, no, I'm not here to change the new product. I want to find the best maintenance master in your store." Ming Chao said so.

Passion is reduced by half, but it is passionate after all.

Within a few minutes, a middle-aged man in his forties came to Mingchao and said, "What's broken? Can you tell which part is wrong? I'll just take the accessories."

"Nothing is broken." Ming Chao handed over a 500 tael silver note: "It will take the master a while, I will ask two questions."

The middle-aged man was stunned for a moment and pushed Mingchao's silver note with his hand: "What do you want to ask?"

"Well... a few days ago, I went to a nearby village. It happened to be the autumn harvest and saw farmers harvesting rice."

Middle-aged man:?

Ming Chao turned his head and pointed at the fan: "When they saw them threshing rice, I suddenly thought, if there was a special machine like a fan, which could make their threshing efficiency many times?"

Middle-aged man:??

He thought for a while and said, "You...uh, it's possible...but farmers definitely can't afford that kind of thing..."

Mingchao: "That is, you can do it, but there is no need to make money?"

“…Well, right.”

"Wait and I'll settle the calculations for you." Ming Chao thought for a while and said, "If a village originally planted 100 acres of land, the labor force was just enough, and the land harvest was taken away by the nobles, and the rest was just enough for the whole village to eat for a year.

But if you develop a machine that doubles the efficiency of farming and lend it to them for free, they can plant 200 acres of land this year if there is enough farming.

The additional 100 acres of land will still be collected by the nobles by 30% and the remaining 70%. According to the average output of our country of Fire, it is about 20,000 kilograms of grain, and at the current price of 10 taels per kilogram, it is 200,000 kilograms.

They have tasted the benefits of the machine you borrowed. If you don’t borrow the next year, they will definitely buy it, and they may buy it more. Isn’t this 200,000 taels enough?

Of course this is the ideal situation. If you encounter a wasteland or have natural disasters and man-made disasters, you will lose money, but I think the opportunity to make money is still greater than the opportunity to lose money, right?

Whether to bet a bet, it may take five years to sell your machine throughout the ninja world, and the richest man in the country of Fire is you."

Middle-aged man:???

He felt that it seemed to make sense, but there seemed to be some problem. He hesitated: "A village only has a fixed amount of fields. How can it be doubled in efficiency and double the harvest?"

Ming Chao: "Where are you cooperating with the ninja? There are too many woods in our country of Fire. What if the ninjas cooperate to reclaim wasteland? Let the ninjas collect money one year later. If the 200,000 taels are not enough for you to share, you will owe another year, 400,000 or even more silver notes, which is always enough to pay it back, right?"

This time, the middle-aged man was silent for a long time.

Then he suddenly sighed with great pain: "I can't make the machine you mentioned."
