This wall is shaped much like a human ear, with the upper pinna in the north, the earlobe in the south, the pinna in the east, and the tragus in the west.

In order to facilitate outsiders to enter the city, a total of five gates should be built, one in the north and one in the south, and the longest three gates in the eastern city wall, among which, the city gate closest to the north will be transformed into a passage for trains in the future, so that trains can enter and exit the city normally.

The scale of the construction of these five city gates is not small, and now the two city gates in the east are being built, after all, both the number of craftsmen and the number of building materials are somewhat insufficient, and they can only come step by step.

The number of craftsmen who are responsible for building the wall is not much, most of the craftsmen are responsible for transporting the soil and compaction, because the wall only needs two very thin walls, the amount of work is not very large, and the width of the soil between the two walls is as high as three zhang, although it is to take the soil nearby, but because the soil required is too much, therefore, the labor required is also more, in addition, compaction also needs manpower, and in order to build the city wall more solidly, it is necessary to make the wall and the soil compaction synchronous, so that the best effect.

In fact, if the material is insufficient, the wall can be replaced by mud, and the rural tile houses of later generations, when building, many of them use loess as a binder, and there is not much of a problem, that is, the walls of the house are easy to crack.

However, for the sake of the quality of the city wall, Li An still decided to use cement mortar, and if there is any cement surplus in the future, he will also apply a layer of one-finger-thick cement mortar on the surface of the outer city wall, so as to further increase the defensive power of the city wall, and at the same time, make the outer wall of the city wall look neat and classy, and can also cover up the small steps generated by the retreat of each layer of bricks, so as to further prevent the enemy from climbing the city wall.

"Li Shilang, it's just such a simple compaction, I'm afraid it's not enough! Not strong enough. ”

One of his subordinates saw the wall designed by Ang Lee and spoke.

In fact, many ancient city walls were made of whole soil, not brick walls seen in TV dramas, and there were not so many brick materials, unless it was an important city such as the capital, it was possible to cover the appearance with a layer of stone or bricks.

Even the Great Wall, which has attracted worldwide attention, is a wall made of yellow mud in some areas, but it is only in the mountainous areas with stones that it is the Great Wall of stone.

And you must not think that the city walls made of loess are all tofu scum projects, it is a big mistake, the city walls made of loess in history, many are very strong city walls, for example, the capital city of the Xiongnu nation is a city wall built of all clay.

However, the walls of this city are extremely strong, and the walls built of stone are not weak at all, and it is said that the Xiongnu leaders gave extremely perverted specifications when building the walls in order to ensure the solidity of the city.

That is, the construction party responsible for the construction and the inspection party responsible for the inspection, one party must be executed, the specific method is that after the city wall is built, let the testing party poke with the iron vertebrae, if the iron cone can enter the length of the city wall one inch, it means that the construction craftsman of the city wall cut corners and will be executed, and if the length of the iron vertebrae pierced is less than an inch, that is, the person in charge of the detection does not use force, and the person who detects it must be executed.

Under such a harsh system, the craftsmen in charge of manufacturing would do everything possible to make the walls extremely strong, so as to ensure that the inspectors could not penetrate an inch deep, and the inspectors were afraid of being executed, so they would also use all their strength to try to pierce the iron cone to a depth of an inch during the inspection, so as to save their own lives.

Both sides wanted to save their lives, so they competed, and in this way, they tried to restrain each other, so that they could improve their skills step by step, and finally make the walls extremely strong.

This kind of city wall piled up by using human life is very inhumane, but the solidity of Tongwan City will also be recognized by the world, and this strong city wall is just a pile of mud.

Therefore, as long as you build it with your heart, the city wall made of clay can also be very strong, but it also takes a lot of energy, and Li Ang asked the craftsmen to compact it with their feet casually, it is obviously impossible to create a solid city wall, and Li An relies on only two brick walls inside and outside, and does not care too much about the internal soil structure.

"It's not strong, will it?"

Ang Lee said with a smile.

The subordinates hurriedly said: "Li Shilang, if the enemy army attacks and excavates the city wall under the city wall, as long as the outermost layer of brick wall is destroyed, it will be easy to dig the inner earthen wall, although the earthen wall is three zhang thick, but if it is not strong enough, it will not be long to dig!" ”

If the thick earthen wall is not tight enough, the defensive power of the city wall is questionable, and it is likely to be cracked by the wall digging technique of the besieging side, and the stronger the earthen wall, the more difficult it is to be dug through, and the longer it takes.

In war, time can represent victory or defeat, if the city wall can be dug earlier, the besieging side will have a great advantage, and if it takes a long time to dig a part, the defender will have enough time to deploy troops to plug the gap.

Li An naturally understands this truth, however, the population size of this port in the future can reach hundreds of thousands, or even more, the defensive soldiers and horses will be very sufficient, and the military technology is particularly advanced, so where will there be any enemy who dares to hit this city, building the city wall is just for good security, and there is a necessary defense, and there is no need to pay special attention to defense, if it is really pressed by the enemy and can only rely on the city wall for defense, then the Tang Empire may have declined, even if it can hold on for a while, In the end, it will be lost, the offense is always the best defense, and the defense is very necessary to engage in, but it can only be a subordinate position, and it must be ranked after the offense.

"There is some truth to your worries, however, our current number of craftsmen is limited, manpower is very insufficient, there is no need to strive for excellence on the city wall, as long as it is almost on the line, do you think anyone will dare to attack the city of the Tang Dynasty, the biggest role of building the city wall is the necessary defense and image engineering, and it is for the stability of public security, if such a large city does not make a city wall, it seems inappropriate."

Ang Lee opened his mouth and said what was in his heart.

The subordinates nodded and said: "What Li Shilang said is also right, my Tang Empire is so strong, where will someone come to provoke, the city wall does not need to be too strong, just enough, enough." ”

Li An smiled, and when he looked up, hundreds of soldiers escorted a large amount of timber over, which was a little irregular, and at first glance it was construction waste after the demolition of the building.

"What are these things, where did they come from?"

Ang Lee asked.

"Li Shilang, these are the materials for building the Arrow Tower! There are more than 30 villages around, each village has several arrow towers, which were originally used to deal with the remnants of pirates, but now, all the pirates have been annihilated, and it is useless to keep so many arrow towers, so before the soldiers and horses of each village are evacuated, all these arrow towers are dismantled and transported back together, anyway, the port needs building materials everywhere, and these materials can more or less alleviate the port's demand for resources. ”

The subordinate hurriedly replied.

Li An nodded with satisfaction and said, "Well done, I know how to live, I know how to save, haha!" ”

This order has not been issued by Li An, his subordinates have already done it, and it is very correct, which really did not disappoint Li An, these arrow towers lost all their role after the pirates were annihilated, and it is a waste of resources if they are not demolished, and after they are demolished, these materials can still be used, which can greatly alleviate the demand for wood for port construction.

However, seeing these soldiers, Li An suddenly felt that he should let them do something, after all, now that the pirates have been completely annihilated, the army of more than 10,000 people can be said to have basically no combat mission, and the task of defense does not need so many people at all, rather than letting these soldiers have nothing to do, it is better to let them join the ranks of craftsmen, of course, this is temporary.

If you let these soldiers work for no reason, do the work of craftsmen, they must be very reluctant, and they will not be able to make trouble, but there is a saying, called money can make the ghost grind, as long as these soldiers are given some additional subsidies, they can soothe their dissatisfied hearts, so that they are willing to work, as a soldier does not earn much, if you give extra money, why don't they do it, for what reason to refuse?

"More than 10,000 soldiers are responsible for defense, which is really too much, if 6,000 people are sent to help the craftsmen, will the progress of construction be increased?"

Ang Lee opened his mouth to say that it was feasible.

"Li Shilang, some of these soldiers have already done the work of craftsmen, and there is no problem in getting started, but they must give more money, otherwise they will be dissatisfied."

The subordinate spoke.

Li An nodded with a smile and said, "Needless to say, how can this official not give them enough subsidies, hahaha!" It's settled, you take care of the arrangement! ”

"Yes, my subordinates are commanded."

One of his subordinates answered, turned around and went to prepare.

If it weren't for the fact that the number of craftsmen was too tight, and the scale of the construction of the port was too large, Ang Lee would not have bothered these soldiers, and it could be regarded as a helpless choice, anyway, there was money.

"Do a good job, do a good job and process money."

Ang Lee loudly boosted morale and told the craftsmen to work harder.

In fact, personally come to inspect the work of the craftsmen, also has the role of supervision, as long as Li An personally comes, the subordinates in charge of the project must also accompany together, so, there is a large group of officials watching from the side, the craftsmen who work are not the slightest chance to be lazy, the work must be full of passion, and the progress of the project can naturally be slightly accelerated.

In the evening, Li An returned to his lodgings, and after dinner, asked his subordinates about their opinions on the work.

"Back to Li Shilang, the soldiers are quite satisfied with the compensation, most of them are willing to work, and there is no pressure to transfer 6,000 soldiers and horses from more than 10,000 troops to be responsible for the work."

The subordinate replied happily.

Li An looked very happy, nodded, and said: "Okay, it's really good, you have done a very good job in this matter, and from tomorrow, you can let the soldiers go to work." ”

"Yes, Li Shilang."

The thought of having 6,000 soldiers and horses join the ranks of the craftsmen made Ang Lee's mood particularly good, which meant that the work could be carried out faster, so that he could feel more at ease when he left here.

After the gradual increase in merchants, the night lighting work of the port is getting better and better, and in the core area of the city, almost all of them are very bright, and there is no need to worry about tripping over anything when walking at night.

Li An naturally went out for a walk after dinner, and walked to the place where the pirates were tied, and met a lot of soldiers talking about work on the way, these guys were quite happy when they talked about additional subsidies, especially some soldiers who had worked before, and they were very original, anyway, they were idle, and there was nothing bad about making more money, no one would give money and couldn't get by.

"Yikes! Go to hell! Go to hell! ”

Not far ahead, an angry soldier rushed over to a pirate for no reason, punched and kicked him, and after the fight, he paced away contentedly, as if nothing had happened, and there were several soldiers snickering behind him, not knowing what he was laughing at.

Li An walked over, looked at a few smiling soldiers leaning forward and backwards, and asked, "What are you laughing at, what are you so happy about, tell this officer about it." ”

"Li Shilang."

Several soldiers were startled, how could they have imagined that Li An would suddenly appear behind them.

"It's okay, the officer is just passing by, just say anything, the officer won't blame the soldiers who tell the truth."

Li An's gossip heart rose and asked.

Several soldiers were still a little hesitant, as if this matter was not easy to talk about.

"Li Shilang forgive the sin, a few of us went to find Xiaoniang to relax, there is a brother who is going to that kind of place for the first time, and the result is only a blink of an eye...... That's it. ”

One soldier said stiffly.

When Li An heard this, he immediately understood, and said with a smile: "In this way, it was the little lady of the Qinglou who made fun of the soldiers who left just now, making him feel that he had no face, didn't he." ”

They are all people who have come over, how can Li An not understand this kind of thing, and his heart is like a mirror.

"What Li Shilang said is that that's the case, this brother just loves face too much."

"It's also the little lady of the Qinglou who is not sensible, how can she make fun of the benefactor? It's too unusual. ”

The soldier responded.
