After many years of operation in the Lion Country, the scale of Tanar Harbor is already relatively large, and it is no problem to dock hundreds of merchant ships at the same time, however, considering the more prosperous commercial trade in the future, this capacity still seems to be a little small, and it should be increased at least tenfold to reach a scale that can dock thousands of merchant ships at the same time.

The expansion will take many years to complete, and if it goes well, it will be three to five years, and if it is not supported by a large dredging ship, it will not be impossible to delay it for more than 20 years, but as long as the money can be made, the expansion will be accelerated.

At this time, the Tanar seaport had two harbor basins that did not interfere with each other, just like two large square pools with small openings, one was civilian, and the other was a military harbor basin, and the facilities of the military harbor basin were completely different from those of the civilian harbor.

In the shallow water near the shore of the military harbor pool, three tall arrow towers are set up, the highest part of these three arrow towers is at least three or four zhang high from the water surface, divided into three layers, each layer is enough to garrison more than a dozen archers, in addition to the fixed high-power crossbow, the top platform, there is also a trebuchet, the defensive force can be regarded as relatively strong, but in the face of general attacks, it is not at all effective to resist Datang.

The number of guards of the three large arrow towers can reach 200 people at the highest, and these facilities have not been demolished, they have been well preserved, and they must be repaired and strengthened, because for general defense, these three arrow towers are indeed very practical and worth keeping.

The three arrow towers in the water were outpost guards, and a few hundred paces behind the harbor land, there were seven arrow towers of different sizes, three of which were much larger than those in the water, and a few of which were slightly smaller.

The total number of arrow towers in the entire port adds up to ten, not counting the watchtowers that can only accommodate two or three people, these watchtowers can also be used as arrow towers, but the area is too small, only one floor, and the power of the attack is very small.

Ten arrow towers can accommodate up to 600 people, forming a high-altitude strike force in the port to ensure the safety of the port, and in a position in the port also built several rows of barracks, some are one-story houses, some are two-story buildings, these houses are for the defense of ten times the residence, such a camp can accommodate up to two or three thousand soldiers and horses, as long as ten times all are full, the defensive force is still considerable.

On one side of the barracks was a grain depot, in which there was still a lot of food left, these were the food sources for the soldiers stationed there, and they were never empty, as long as there was food, the morale of the soldiers could be maintained at a high level.

The training place is outside the barracks, there is an archery range, a training ground, and a small racecourse, which can be regarded as everything.

There is also a modest ship repair yard in this small military port, which allows for a certain degree of repair of damaged ships and allows them to return to battle.

The draft of the military port is only four or five meters, it is not a deep-water port, and many large ships in later generations are difficult to enter the port, however, the ships at this time are generally smaller, and even the draft of the steam gunboats of the Tang Dynasty is not so large, so they can be docked inside.

For such a very good military port, Li Ang felt that it must be preserved, and he should continue to invest funds in repair and construction, so as to build the entire military port into a model military port of Datang in the subcontinent, so as to deter the surrounding areas and ensure the smooth flow of the Datang Maritime Silk Road.

Larger civilian harbors, facilities are much more than military ports, because it is a civilian harbor, so, the defense facilities are pitiful, the shallow water area of the port, there are only two watchtowers, with the role of lighthouses, there is a small shed to shelter from the rain, the single-storey platform below is only three steps long, and a hanging brazier can be placed in the middle, so that the ships entering the harbor at night will not go the wrong way, in addition, three or two archers can also stand on the platform, responsible for monitoring the ships inside the harbor, once the danger is found, It will immediately send a signal to the superiors in the back, and if necessary, you can ask for help from the opposite military port.

There are also very few defenses on the shore, only a few watchtowers that are similar to those in the water, which can provide the minimum level of defense needs against thieves and thieves, but it is completely sufficient, and its main role is to monitor and monitor every move in the harbor.

Due to the large size of the civil harbor, there are many fishing boats in the shallow water area on one side, and these fishing boats are close side by side, which is very crowded.

In order to facilitate the entry and exit of fishing boats, a suspended wooden path has been built in the shallow water area for people to walk, so that fishermen can easily enter and exit their fishing boats.

On the shore near the fishing boats, a number of fishermen's huts have been built, which are single-storey, and they are filled with fishing nets and other items that fishermen need to use, as well as some dried fish to dry.

Under normal circumstances, the man is responsible for going out to sea to fish, and after the catch is returned, the woman is responsible for cleaning and drying, so that the division of labor and cooperation can make life better.

Drifting at sea for a long time makes these fishermen very dark, and of course, it is also a very healthy complexion.

The arrival of Nan Tianzhu's soldiers and horses caused a lot of harm to these fishermen and their families, but Li An dealt with some of Nan Tianzhu's evil soldiers very harshly, so that the lives of these fishermen quickly entered the right track and their lives became stable.

Since the fishermen catch a large amount of fish, they emit a great smell when they are dried, and a gust of wind blows and can spread the fishy smell of the fish to far away.

Fresh marine fish can be sold at a good price, of course, the variety must be very good, if the variety is not good, then it will not be sold at a good price.

Every day, many people wait in the harbor for the fishermen to return from fishing, and they will buy the fish as soon as possible and sell them at a higher price.

The location of the fishermen's wharf is the most remote and the worst location of the port, after all, their goods are fresh sea fish, which is somewhat polluting, and the best wharf location is naturally given to merchant ships.

Merchant ships come from different countries, and the goods they carry are also very rich, and the commercial value is far more than that of fishing boats, so it is best to give up the largest position to merchant ships.

As soon as all merchant ships approached the wharf, a large group of people came running in search of work, known as wharf laborers, who were responsible for moving goods in order to earn the money needed to survive.

The goods on the merchant ship are loaded in large boxes, and each box is very heavy, so many coolies are tired and bent over, which looks quite hard, but as long as they can make money, the hard work is worth it.

There is also a not too large shipyard on one side of the port, this shipyard occupies a relatively large land area, but occupies a relatively small water area, a lot of wood and materials are placed in the house on the land, there is only one dock in the water, only one medium boat can be built at a time, or a few small fishing boats, it is a very weak shipyard, and what is currently being built are several small fishing boats, which are ordered by fishermen here.

The expansion potential of the harbor is very large, as long as it takes a lot of effort, it will definitely be able to expand into a large harbor, perhaps because of too much confidence, there is no city wall on the land of this harbor, only a simple fence built of wood, this kind of fence can only block ordinary people, if it is a thief, it can easily climb over the fence, enter the harbor at night, but there are many watchtowers in the harbor, which are equipped with soldiers armed with bows and arrows, so it takes courage for thieves to dare to enter.

Ang Lee considered the overall situation and decided to build Tanar into a dazzling pearl on the Maritime Silk Road, for which a huge amount of construction costs must be invested.

Fortunately, the Lion Nation promised to compensate for a huge amount of wealth, as long as this compensation is in hand, except for a small part to appease the merchants and people, most of the funds will be used to build the seaport, among them, Tanar and Godi will be the focus of construction, especially Tanar, because it has not suffered damage from the war, all kinds of facilities are relatively perfect, and the expansion work is easier to carry out.

In order to achieve the optimal construction results, Ang Lee decided to personally inspect the situation of the harbor and design it.

Li An first came to the military port, and visited the Tang soldiers in the military port, asking them to rest more and train seriously.

"Li Shilang, the facilities of this military port are quite perfect, but there are too many garrisons and horses needed, and six hundred people are needed to fill the ten arrow towers, which is too much, and some changes need to be made."

The subordinates understood that it was not easy for Datang to garrison troops overseas, and the personnel needed to be as refined as possible, and they could not use too much manpower to defend a seaport.

Li An nodded and said: "You are right, you can't be so labor-intensive, but since these arrow towers are all intact, there is no need to demolish them at all, just use them as watchtowers, one arrow tower can be used by five people, so that fifty people can defend it." ”

"Li Shilang, this person is missing, but in this way, the defensive strength is too weak, and it still needs to be improved."

The subordinates felt that this was still not a good idea.

Li An pointed to the two most critical defensive positions, and said: "These two positions are the most important, to build two strong towers, four artillery pieces are placed on the top of each tower, and ten soldiers are enough to defend it, so that the enemy within a radius of several miles cannot get close to the harbor, and at the same time, a large number of archers are also omitted." ”

"Li Shilang is right, in this way, the soldiers guarding can be reduced a lot, but the strength of the guard has been greatly strengthened, the range of artillery is much farther than that of bows and arrows, and only two artillery towers are needed to completely control the military port, so that the enemy does not dare to approach."

The subordinate agreed.

In any era, if you want to reduce personnel and increase efficiency, the best way is to use more advanced equipment, only more advanced equipment, in order to achieve the result of reducing personnel and increasing efficiency, and Datang now has artillery, only need to erect a few artillery, the deterrent effect can be far higher than that of a large number of archers, and the combat effectiveness of a turret is more than ten full arrow towers.

The construction of two brand-new turrets in the military port is the best improvement plan that Li An can think of at present, as for the expansion of the scale or something, the funds are not in place for the time being, and the dredging ship is not in place, so it cannot be implemented.

After investigating the military port for a while, Ang Lee went to the civilian port, where the potential for change is greater, because the area is larger, the facilities are more, and it can also produce great economic value, so the need for change is also the greatest.

Military ports are more concerned with safety, while commercial ports are more concerned with commercial value, so the premise of the change is to improve economic efficiency as the ultimate goal.

More than half of the civilian ports are used for commerce, and fishermen occupy a small amount of land, while shipyards occupy only a small area.

In the future, commerce will become more and more prosperous, so this commercial port is absolutely not enough, and it is necessary to continue to expand the commercial berths in the shallows a few miles away, or even a few more, of course, the original port can also extend the distance to the deep sea, so that the water area is larger, and more ships can be berthed.

Fishermen have a limited amount of catch, shipyards don't have much to occupy, and only the loading and unloading of merchant ships is the most troublesome and labor-intensive.

Li An walked near a merchant ship that was unloading, and looked at dozens of coolies working hard to carry the supplies on the cargo ship, and suddenly felt that this phenomenon had to change.

These coolies are very tired, but the efficiency of the work is not high, it often takes a lot of time to unload all the goods of a ship, and the space of the wharf is limited, there are many ships waiting to be unloaded, and some merchant ships need to wait for a day or two to unload smoothly.

Of course, there are still many ships that need to be loaded, and there are even more merchant ships that need all kinds of supplies, after all, merchant ships travel long distances, need to supply fresh water and food in the port, and also need to buy various daily necessities, all of which need coolies to carry them, and the physical strength of coolies is limited, and the efficiency of work is naturally not high.

If this situation cannot be changed in time, it will inevitably greatly restrict the development of port commerce, which is very unfavorable.

There are three ways to remedy this inefficiency, the first of which is the simplest and most straightforward, and the easiest, which is to increase the number of coolies and get more people to work in the port to speed up transportation.

The second is similar to the first, which is to build more berths, and after more berths, more ships can be loaded and unloaded at the same time, and of course, there is more demand for coolies, which is also something that must be done in the later stage.

The third method is to use the mechanical arm to transport goods, so that the efficiency of handling can be improved many times, and the saving of manpower is also very large, which is a very good method, which can greatly increase the throughput speed of port goods.
