The stronghold built on Peace Island was not large, about the size of a dock fort. More precisely, a barracks with small walls.

Originally, it would have been safer to build a castle. After all, the castle was much more defensive. However, in Marin's plan, this stronghold on Peace Island was only a temporary stronghold. Even if you want to build a castle, it has to be built on land by the Keelung River, not on Heping Island, a small island the size of a palm.

Therefore, the final choice was to build a barracks with small walls on Peace Island as a foothold. Anyway, this stronghold, the threat it faces, at most, is scattered pirates, and the barracks with walls are enough to resist.

Now is not the Jiajing period, and the Japanese have not yet become bigger. The current Japanese are generally only a few dozen people, and those with more than 100 people are considered large-scale. It was only after the merger with the Ming Dynasty pirate organization that the Japanese became bigger, but not yet. Moreover, the authentic Japanese are just some down-and-out samurai with swords, and they have no ability to attack the city. Therefore, a small wall, with muskets, was enough to deal with the fallen samurai.

In addition, unlike the general city wall, the newly built stronghold city wall is "covered". In this way, even if it rains, it will not affect the use of guns.

Keelung faces the Pacific Ocean and has many rainy days every year, so it is also known as "Rain Harbor". If the walls were uncovered, the guns would not be able to be used if it rained. It would be dangerous to encounter a strong martial artist who took the opportunity to climb the city. Therefore, according to this characteristic, Marin specially ordered the construction of "covered" walls, and there were also protruding "cornices" that would allow muskets to stick out of the walls. In this way, the musket is not easy to get damp when firing.

Originally, Marin also planned to help build a compound in Jilong Village. Unexpectedly, the iron tools that Kong Tai left them last time were fully used by them to dig a large amount of stones. Then, without waiting for Marin's men to arrive, they themselves built a large stone wall out of stone, which had good protection.

Peace Island is not an alluvial island of the estuary, but a subsidence coast. In other words, it was separated from the main island because of subsidence.

Therefore, on Heping Island, there is a lot of stone that can be mined. Although it is not a precious marble, it is enough for the construction of walls and fortresses.

However, the stronghold built by the Beihai Kingdom on Heping Island is not intended to be made of stone. Mainly, when the stone is mined, it is too slow. Therefore, 100 masons from Beihai directly began to unload bricks from the ship, and then began to mix cement, preparing to build an ordinary wall of later generations with bricks on the inside and cement on the outside.

Of course, because there is a defensive role. Therefore, the wall is not hollow, but solid.

But even then, the defense of the fence was not very high, and the main thing was to fear shelling. After all, the cement outside the city walls is just an ordinary coating, and there are no steel bars as "bones". The cement wall without muscles and bones is also afraid of the bombardment of iron balls and shells.

But fortunately, there are no cannons for the Japanese guards here. Moreover, this stronghold is also temporary. When it comes to building the castle on Keelung land, you will definitely need to use the bones.

However, even if it is a castle on land, the bones used are only bamboo. Of course, that's enough. Taiwan Island has bamboo, after all, it belongs to the East Asian ecosystem, and there is a tenacious creature like bamboo. The cost of steel is too high, and at present, only the capital city of Beihai is reinforced concrete outside the city walls, and other places have not been used. Because, not to mention that there is not much steel now, it is also more difficult to process steel into steel bars. Nowadays, there is no machine for wire drawing, and all the wire rods are drawn by hand by blacksmiths, which is very expensive. If reinforced concrete is used everywhere, if you have money like Marlin, you will also go bankrupt. It just so happens that there is bamboo on Taiwan Island. Therefore, Ma Lin plans to use bamboo reinforced concrete when building fortifications and river embankments on Taiwan Island in the future. Although the effect is not as good as that of reinforced concrete, it is cheaper. For things that go in volume, cheap is king. The quality of Huaxia industrial products in later generations is not good, but why can they sell well all over the world? It's cheap. The rich will pursue quality, and the poor will only look for price...... And for now, the vast majority of the world's population is poor. Therefore, low-cost things are king. As for the quality, just make do......

Of course, it depends on the stage. For example, in later China, in the 20th century, everyone was very poor, so bargains were very popular. But before Marin crossed, many people had money in their hands, and their pursuits were immediately different. bargains, they are no longer sought after. There are many models with gold chains, and he is not willing to buy them at a low price......

……

When the dock fort was built, Liu Laogen, the shrewd village leader of Jilong Village, took the initiative to help with the situation in the village. Of course, Kong Tai did not treat them badly. Every day at noon, Kong Tai would give the help to the cooks. In addition, there is a daily salary for each person. But Liu Laogen doesn't want money, just grain and salt. This thing is the rarest thing for villagers living overseas. Of course, those iron farming tools brought by Kong Tai made their eyes even hotter.

Kong Tai did not disappoint the villagers either, he announced that after the stronghold was repaired, he would give the villagers a batch of iron farming tools. As a result, the villagers worked harder.

Then, Liu Laogen gave Kong Tai another big surprise - he told Kong Tai that in order to build the village wall, the villagers had collected a large amount of stones. Nowadays, there is still a lot of stone to spare......

Kong Tai directly understood and gave the batch of iron farming tools in advance. And Liu Laogen also took out the surplus stones that had been piled up in the village before and gave them to Kong Tai.

After receiving this batch of stones, Kong Tai was very happy. He commanded loudly:

"Take all these stones and lay the foundation!"

Laying the foundation with stone can make the building stronger and stronger. Marin once told Kong Tai that there are many earthquakes on Taiwan Island, and the building must be strong enough. And it's better not to get any high-level. Otherwise, the shock will be gone. Moreover, those who live on the upper floors do not have time to flee for their lives......

Therefore, the houses built within the high walls of this stronghold on the island of peace are all bungalows, and they are not small apart from each other. If there is an earthquake, it is easy to run out.

Of course, bungalows made of cement bricks are not so easy to collapse. Only when there is a big earthquake will it collapse.

In addition, for a big man like Kong Tai, his bed is also specially made in order to be shockproof.

How to make it? It's the whole bed, which is actually a steel bracket. Moreover, the bed has an iron lid on it. Even if there is a big earthquake, the roof collapses, the bed is covered with an iron cover, and the bungalow collapses is not a big threat, and the people sleeping in the bed will not be in danger.

Of course, this is just Marin's unfounded worries. In fact, how can there be such bad luck as a major earthquake? A major earthquake is a once-in-a-century earthquake. However, it is also possible to be prepared in this way.

Even, in the future, Marin plans to build a reinforced concrete house on the island for his youngest son Ma Yun. Ma Yun is the person who wants to be the owner of the island in the future, and he lives here all the year round, and the possibility of encountering a major earthquake is not small. Therefore, it is necessary to build a reinforced concrete house with strong earthquake resistance. Although the cost is relatively large, the use of steel bars for a single house is still affordable for Marin......

And this newly repaired stronghold, Ma Lin named Majiabao, and the first owner of the castle was naturally Master Kong Taikong......
