Yang Hao stayed here in the mine for a few days and inspected the surrounding area.

The geographical location here is very good, easy to defend and difficult to attack, as long as there are several key positions, set up passes, it is a husband and a man to pass.

Yang Hao was very satisfied with this place, and after drawing a map of the transaction according to the results of his inspection, he handed it over to the local guard and ordered him to garrison it at this location.

He had no interest in Sanmiao or the rest of the tribes, so he explained to the leader of Youyu, paid attention to the people who could make ships, and led everyone to ride north.

There is still a long way to go for iron to become widespread on a large scale, and the most difficult way is how to make steel.

The difference between iron and steel is the amount of carbon, Yang Hao doesn't know what is the steel frying method, and he doesn't know what the blast furnace is.

His only idea is to refine it into steel, and to put it bluntly, it is to constantly beat the red-hot iron to beat the excess carbon out of the pig iron.

As a modern person, Yang Hao is naturally not stupid enough to use manpower to do this, which is too inefficient to meet his requirements.

His only reliance was on the improved transmission technology based on the windmill principle, which was not yet mature, but barely functional.

The windmill is used to grind the surface, but it is a little incapable of making steel, Yang Hao can only think about starting to prepare for the construction of hydraulic equipment after going back.

This is another complicated project, and Yang Hao has a headache.

Finding basic industries and livelihood facilities from scratch is like flowing water, which makes people's scalp tingle when they think about it.

Today's infrastructure is just a drop in the bucket, and it is tens of millions of miles away from the idea in Yang Hao's heart.

And if it all unfolds like this, it will almost wipe out the family wealth that Qi Guo has accumulated in the past few years.

Yang Hao was having a headache about this matter on the way back to Lingzhou City, grabbing money, food, and girls, this sentence is not very applicable to today's Qi State.

Today's Qi State is like the Central Plains Dynasty in later generations, and there is no interest in those barbarians who are poor and tinkling at all.

The looting of what they got was not enough for the food and grass that the army spent on the expedition.

The only thing that can make Yang Hao interested in these forces is population and land, but now the population of Qi has reached the limit of what it can bear.

This means that he has no way to alleviate Qi Guo's current embarrassing situation from the outside world, so he can only find a way to solve it from the inside.

Yang Hao, who was heavy in his heart, had no intention of continuing to play after returning to Lingzhou City.

Ignoring the complaining gazes of his beloved concubines, on the third day after returning to Lingzhou City, he hurriedly went north.

When he came, Yang Hao spent nearly three months, and when he went back, he returned to Chang'an City in less than a month.

There is no complete road, and he still has his female dependents and seniority, and he can return at such a fast speed, you can imagine how urgent Yang Hao's mood is.

When I left, I was farming in Chang'an City, and when I returned, it was almost harvest season.

The arable land outside Chang'an has increased a lot compared to last year, and people are waving their heads in the fields and carefully clearing weeds.

In the wasteland in the distance, a few old cows lay leisurely in the shade of the trees, enjoying the leisurely afternoon.

The majestic outer city of Chang'an City has been preliminarily completed, and the cyan city wall allows Yang Hao to find a feeling that he has not felt for a long time.

Looking at the majestic city in front of him, Yang Hao was full of emotion, as if he was in another world.

It's been nearly six years since he came to this world, and he is racing against time to elevate civilization to the point where he is today, like a workaholic, and only he understands the difficulties of it.

The ministers had already received the news that Yang Hao was going to return, and they waited out of the city early.

Yang Hao met a person who surprised him a little among the people who greeted him.

There is still a chieftain.

Seeing this, Yang Hao hurriedly invited his eldest brother to ride in the same carriage with him.

On the way back to the palace, Yang Hao asked: "When did my brother come to Chang'an, why didn't I say hello, if I knew that my brother was coming, I would definitely come back earlier, wouldn't it be a snub to my brother." ”

Seeing that Yang Hao treated him so politely, Ren Yu was naturally secretly refreshed in his heart.

If a year ago he still had the ambition of using Great Qi to realize his ambition to dominate the world, but since Qi defeated Youqiu with a thunderous force, his ambition has been somewhat shaken.

Unlike the defeat of the Zhuxia coalition, the shock of defeating the poor team was far stronger than that war.

This time, instead of following the turtle-like wall defense, the Qi State used far less troops than the enemy to inflict heavy losses on the arrogant Youqi.

He also knew that this was not all the strength of Daqi.

This made him feel frightened, and thinking of such an opponent on the way to dominate the world, Ren Yu felt a burst of despair.

With a hint of luck, he wanted to go to Qi Country to see the reality of Qi Country in person, but this look completely made him die.

The changes in Qi are too great, and compared with Qi Guo, all the money from his own family is not enough for others to stuff their teeth.

Ren Yu couldn't understand why Qi Guo could change so much in just one year.

For the primitive tribes that have not changed much for hundreds of years, the development speed of the Qi Kingdom is simply a monster.

He didn't dare to imagine that if he gave Qi State another period of time, this newly rising force would become all kinds of appearances.

He was a little glad that he had made a wise decision to let his sister marry Yang Hao.

Giving up his plan to fight for hegemony, Ren Yu only hoped to reap some benefits from the rapid development of Qi State, and most importantly, he wanted to know if Yang Hao had any plans to annex him.

His former ally has become a feared presence for him, which makes him a little restless.

Ren Yu tried his best to show that he was neither humble nor arrogant, and squeezed out a smile and said: "Yang Li is poor and poor, and the prosperity of Daqi's martial arts makes a certain admirer, but it's a pity that I know it late, I wanted to come over to celebrate with you, and I came here to learn that you have gone to the south, it's really a pity, a few days ago, I was planning to leave, but I never thought that today I still have the opportunity to drink with Yang." ”

Yang Hao said: "Brother praises the little brother too much, it is a fluke to win this battle, there is no reason to celebrate, the brother can come to my Chang'an thousands of miles away, the little brother is moved in his heart, brother rest assured, today I will have a good drink with my brother!" ”

Ren Yu laughed when he heard this: "Refreshing! ”

Everyone saw the two talking and laughing, and they looked like brothers and harmonious, but they didn't know that the two had already secretly scolded each other.

The banquet of the Qi Kingdom is far from being comparable to the rough open-air barbecue of Youyu, and the sumptuous dishes surprise even the well-informed nobles.

Ren Yu has something on his mind, even if the food is in front of him, there is half an appetite there.

With the strength of the wine, Ren Yu said softly to Yang Hao as if he was drunk: "Actually, I already knew that Ren Zhong was here with you. ”
