In the north of the town, two big golden characters lie quietly above the two city gates in the north and south, the word Zhenbei is a simplified character written by Li Yuanji himself.

Li Yuanji didn't explain much, just smiled slightly, leaving people with an inexplicable sense of mystery.

It lasted two and a half months, the city wall with a total length of eleven miles, three meters wide and ten meters high, has been completely completed, the concrete poured city wall, from a distance, it makes people feel a sense of awe, and when they arrive at the city, they will be shocked by the grandeur of this city wall.

The main structure of the city wall is almost identical to that of the gate tower in the Taiping Fang, but the difference is that some changes have been made to the interior of the wall in order to save cement.

The front and back are made of half a meter thick concrete, the bottom is also built of concrete, the thickness is the same half a meter, the width of the middle is two meters, with soil and sand and gravel filling, layer by layer, and then compacted, a two-meter-high dark layer is set up at seven meters, and there is a hole as big as a human head, giving people a strange feeling.

The function of this dark layer is that it can actively defend against the enemy who ascends the city, and through the small hole, you can constantly knock down the opponent's ladder or nest car, and you can also shoot arrows from the hole, and the defense of the upper layer is two three-dimensional defenses.

On the top floor, I went to the more conventional battlement-style design, but the highest part of the battlement is two meters high, which can be used as a good cover to ensure the safety of the soldiers defending the city.

Every two miles, there is a tower, along with the city wall, the highest point of the tower reaches 18 meters high, you can see the situation of the entire battlefield, help the commander to transfer troops.

But this is not the most frustrating design, Li Yuanji is designed to treat Zhenbei as his core nest, whether it is north or south in the future, the geographical location of Zhenbei is extremely important, and according to Li Yuanji's direction, it is 200,000 troops to besiege Zhenbei, and in the absence of reinforcements, it will be held at least for more than half a year.

For this reason, the defensive force of Zhenbei City has a full number of 15,000 people, which is almost the same as the garrison of Chang'an.

In addition to the staffing, there is an even more frustrating design, with a three-tiered hedgehog array at the top of the wall, starting from the top of the dark layer.

Densely covered with wooden sticks two meters long and with the top cut down, only a small number of battlements were left unarranged, which were prepared for the besieging enemy, but in the face of such a defense, no one dared to attack rashly.

The exterior of Zhenbei Castle looks spectacular, but the interior is a bit of a surprise.

"The minister thought that His Highness would adopt all rammed earth structures!" Standing in front of a huge construction site, Ma Zhou couldn't help but sigh.

Everyone knows the shortage of cement, and the amount needed to build a city is even more terrifying, and it is normal that the buildings in the city do not continue to use concrete, but this construction site is still made of concrete.

"When the cement production comes up in the future, it will be slowly changed, and one day, all the buildings here will be made of cement structure." Looking at the construction site of Nuoda, Li Yuanji said helplessly in his heart.

"Actually, it doesn't matter, His Royal Highness's definition of Zhenbei is destined to make Zhenbei impossible to become the most prosperous city, and the minister feels that in a few years, there will be other cities to replace Zhenbei." Ma Zhou said that it was okay, but he was depressed in his heart.

He had advised Li Yuanji several times about this matter, but the result was always useless, Li Yuanji didn't listen at all, and insisted on doing it.

As a courtier, what else can I do? So what?

"It is inevitable to replace Zhenbei, but the school must be located in Zhenbei, this is the gate of my Qi country, and it is also a city declared to the outside world, this king just wants them to watch the prosperity of my Qi country!" Looking at the south, Li Yuanji secretly clenched his fists and continued: "Military, economic, academic, this is the core of Zhenbei, as for the rest, just leave it to the city behind." ”

Ma Zhou was secretly silent, once again thinking about the three words military, economics and academic.

Military and economic are understandable, but what does it have to do with academics? And Li Yuanji's emphasis on academics seems to be beyond his imagination.

This also made Ma Zhou feel that the cart before the horse was reversed, the current Qi State, what should be most concerned about the military and population, and other issues should be put behind, but Li Yuanji had to go hand in hand, Ma Zhou suddenly had a feeling of reincarnation of Emperor Yang of Sui.

Emperor Yang of the Sui Dynasty is like this, he never does what he can, and he must carry out ten good things that benefit the country and the people at the same time, but as a result, he made people complain, and finally lost his country, so that he cheapened the Tang Dynasty in vain.

"Your Highness, the minister still thinks this is a little inappropriate." Thinking about it, Ma Zhou still decided to continue to persuade him, Li Yuanji's positioning of Zhenbei is too much, in his opinion, Zhenbei does not need anything else, only a military land, and the others can be placed in the back of the city.

"No, you only see the risks here, but you don't see the benefits here." Li Yuanji shook his head with a smile and said, he didn't say it before, thinking that Ma Zhou would figure it out by himself, but now it seems that he still has some assumptions.

continued: "The establishment of the school here is conducive to the students' exposure to more external things, which is conducive to their studies, and what this king wants is not those who can only care about the rotten Confucianism, but the talents who can solve the life of this life after a few years of study." And the economic interests are more obvious, and after the city is built, the north of the town will only have one purpose left in the economy, transit and overnight. The inns in the city are all operated by the government, and all the income is included in the government treasury. ”

"Your Highness wants to?" Ma Zhou's heart lit up, and he suddenly brightened.

Li Yuanji nodded lightly, exploitation, not more exploitation, where does the money come from?

Li Yuanji, who exploited the people, would not do it for the time being, and there was no reason to do it, and the rest was the caravan that he valued more, not so much that Zhenbei was responsible for the economy, but that Zhenbei was the duty of direct exploitation of interests.

Merchants could have traded directly in the north of the town, then north to the north and south to the south, but then they had to pass through the north of the town to the city to trade.

The city to the north was at least a day's journey away, and the merchants could only stay here, eating, drinking, and lodging, which were the sources of profit.

And Li Yuanji's purpose is to make Zhenbei self-sufficient, save limited resources, and allow himself to maximize the development of other places.

……

There is no such thing as a free lunch, and the same is true for the people who have immigrated here.

The state of Qi divided the land for them, and even gave them food, so that they could support it until the harvest came down, but what it took was that each family had to send a Ding man to work in the north of the town.

Every time the seven-day rations are prepaid, Ding Nan works in the city for seven days, and the government soldiers in various places will give them another seven days' rations according to the order, and they can't eat enough, but they can't starve to death, which is much stronger than staying in the Central Plains.

What's more, hope can be seen here.

I personally experienced the convenience of Yuan Rang plow, and experienced the speed and convenience of the plow rake, the heaviest farm work is the plough and the flat, now these two have been solved, what else is there to worry about? In the end, many Ding men were relieved to leave the farm work at home to the women and children, and then came to the north of the town to participate in the labor with their companions.

"Brother Gun, let's rest for a while, our speed is much faster than others, and we don't have to worry about completing today's progress." The dog threw the shovel on the ground, picked up a bowl of water from the bucket next to him, solved it with a bang, and handed another bowl to the old gun.

The old gun took the bowl and drank it in two sips, and then continued to wield the shovel and shovel the dirt out with a spade.

"I heard from the people who came before that King Qi is very generous in terms of rewards, as long as the work is done well, there is no shortage of food or something, and if you are lucky, you can also divide a piece of meat, my family has a lot, and the food is as much as yours, how can I do it if I don't do more?"

"Hey, that's what others said, we've been here for half a month, right? I haven't seen anyone win a reward until now, old gunman, it's almost there, and we're not slower than others. The dog continued to persuade, but his butt never left the ground.

"Seeing that I haven't seen it, King Qi treats us well, the whole family has food to eat when one person works, and there are so many arable land and pastures, you can't encounter this kind of thing when you are in your hometown, you don't have to do it if you have poor physical strength, I am strong, if I stop, I will feel ashamed." The old gun shook his head, people's abilities are big and small, the old gun never blames others, he only knows his ability, how strong he is, although his philosophy of life has brought him a huge bane, but as of today, the old gun never thinks he is wrong.

"Don't be so grateful to this king, this king likes fairness and justice the most, you work, this king gives food, it is justified!" Li Yuanji happened to walk nearby, and the old gun, who had been working hard, didn't notice Li Yuanji's figure, and the dog who was only taking care of rest also didn't pay attention, but Li Yuanji heard their conversation clearly, and couldn't help but have a good feeling for this old gun.

"Your Highness...... I ......" was caught lazy on the spot, and the dog hurriedly built a shovel with a panicked look, and while working hard, he struggled in every way.

"Don't worry!" Li Yuanji smiled and waved his hand, indicating that he didn't care about him being lazy: "The old gun is right, you have poor physical strength, don't worry about doing less, he has strong physical strength, and you should do more." ”

Putting his eyes back on the old gun's body, his thick back, he shoveled out the dirt with a spade, repeating the same action over and over again, without the slightest hint of fatigue.

"You could have lived a better and more nourishing life, but you used it in the wrong direction, so that you mixed it up like this......"
