A tour of Japan's Warring States Period

Koheta has an idea, but its feasibility has yet to be determined. Without going into detail with Kitahata University, he just said that he had a way, so he and Kitahata University went to the city to report to Yamauchi Yoshitsune, hoping to mobilize twenty powerful Nuggets. Yamauchi Yoshitsune didn't ask the reason and directly agreed. (I hope this boss doesn’t think that he discovered some big gold mine or increased production. This is not easy to explain)

Immediately, a miner and twenty members of the Mashino Jinshan Nuggets were mobilized to Xiaoping Tai's command. Koheita knew that these gold diggers were not ordinary miners, but generally wealthy craftsmen. They usually responded to the daimyo's military service like Uncle Tsunara before. Although they were not samurai, they were also among the middle- and high-income people (of course the kind of direct The situation is different for powerful groups with gold mines. Their leaders and parents are often warriors. After all, they are rich, and the miners are organized and equipped, so they are very powerful.) They also have experience in digging out the water veins of enemy cities and attacking with earth dragons. (One thing that is very sad is that the Japanese also call this method of siege a city by a hole. It probably means digging a hole to attack a city, but if you are reading in Wu dialect, you will find that the word "donggeng" is used in Wu dialect. It sounds like a slightly disgusting part of the human body. Since I am from Changzhou, Jiangsu, when we talk about the tunnel attack method in the future, we will use the term earth dragon attack, above).

Xiaopingtai took them to the boulder and asked them to try to dig a deep tunnel to the other side. It didn't need to be strong and strong, as long as it could hold up until the tunnel was connected.

Yes, Xiaopingtai's method is to dig a tunnel to form a relatively large space underground, and then try to destroy the tunnel. Under the huge pressure of the upper river water and the boulder itself, they will automatically fall into the excavated tunnel, and eventually The boulders will sink deeply, thus no longer posing a hidden danger, and the river will become calm.

The Nuggets first dug a deep pit more than five meters deep by the river. As expected, the water seepage was quite serious. The construction environment was very unfriendly, but it was still barely operable. The soil is also relatively soft, and support issues require careful consideration and planning. Several Nuggets and miners discussed it over and over again, and finally felt that it could be done.

After passing the feasibility certification, the Nuggets thought how it could be constructed, so with the coordination and help of Hokahata University, they mobilized a large number of wooden boards and logs, and then recruited a hundred water workers to start the construction together.

By digging diagonally downward for about five meters on both sides of the bank at the same time, and then digging together, the Lianchuan will be ten meters wide. Although the river channel will become wider due to the presence of boulders, it will not exceed fifteen meters. The total length of the tunnel is less than thirty meters, and Xiao Pingtai also went down several times. It is true that the soil under the river bed is soft and requires a lot of support, otherwise it will easily collapse.

Looking at the dripping tunnel, Mrs. Xiaoping couldn't help but feel a little worried about the nuggets and water traders working underground. However, one of the Nuggets patted a thick log hard, which reassured Xiaoping. I dare not say such nonsense as a ten thousand year prison (but some of us dare to say that there will never be a big flood in ten thousand years), but there is no problem at all in waiting for ten days and a half.

Xiao Pingtai thought about how people dig tunnels with a mountain on their head, which may weigh hundreds of millions or billions of jins. Now a stone on top of your head only weighs hundreds of thousands of pounds, so it shouldn't be a problem. We are not leaders. We don’t need laymen to command experts. We just need to listen to professionals. People said it was no problem, so Xiaopingtai didn't worry anymore.

In less than ten days, the entire tunnel was completed. Xiaoping Tai first roughly estimated the location of the boulder, and then asked them to widen and deepen the tunnel in the estimated direction. To ensure that the boulder can sink deeply into the ground and not get stuck in mid-air.

Xiaopingtai asked the Nuggets how to make the tunnel collapse quickly. The method is also very simple. Generally, when attacking a city, the attacker often suffers heavy losses against tall city walls. But dig through the tunnel to the bottom of the city wall, then stop digging and try to loosen the foundation of the city wall (if you encounter something like the Nanjing Ming City Wall, then this project will be huge. The foundation of the Nanjing Ming City Wall is made of strips of stone several meters thick. , I really admire it), and then use better quality hardwood as temporary support. Finally, pile firewood in half of the space, open a few ventilation holes above the tunnel for ventilation, and then put a fire in, and the walls will be burned down for you.

Therefore, cave sieges have been used a lot in the past. In addition to destroying the city walls, they can also directly enter the city. This kind of earthwork is something that many generals know. It is a general siege technique without much secret.

But now the original disadvantage has become an advantage at the moment. The original tunnel was afraid of water seepage and collapse, and dozens of lives would be taken care of at once. After all, underground, you can't run away even if you want to.

However, the soil on the riverbed was soft and easy to collapse, which was very convenient for Xiao Pingtai who was about to destroy the tunnel. Now that both sides of the tunnel are completely connected, there is no ventilation problem at all. Just think about destroying it quickly.

The first step is to evacuate the people. Before the evacuation, a large amount of straw and firewood were piled up. Then add a certain amount of combustion aid, just sprinkle some oil or something. The main burning point is under the boulder, hoping to quickly burn down the tunnel.

The fire was quickly lit. The weather was already very dry today. The fire in the tunnel was whipped up by the wind that poured in from both sides, and the fire crackled and burned horribly.

In just ten or twenty minutes, a large amount of foam began to form on the river, and slight ripples appeared on the originally calm river surface. The ripples grew bigger and bigger, and the water flow continued to stir the embankment left and right.

Suddenly, there were dull sounds, and the river rolled over. Within a few breaths, there was a loud noise.

The boulder that originally firmly occupied the center of the river suddenly sank with a loud noise, and the river made a thunderous sound. And the entire ground seemed to be shaken by an earthquake, shaking violently, as if it was the roar of huge rocks.

Even Yamauchi Yoshiharu, who was in Fuchu Castle, hurriedly evaded, but as a burst of ash fell, the entire land returned to calm.

At the same time, Lianchuan also calmed down, and the originally turbulent river continued to flow downstream calmly as if nothing had happened.

Hokahata University, who was watching all this, stood quietly on the embankment and remained silent, with a strong momentum of man conquering nature. He ran over and held Xiao Pingtai's hand tightly. He was so excited that he couldn't speak. He just held Xiao Pingtai's hand again and again.

After hearing the news, Yamauchi Yoshiharu also hurried to the riverside after appeasing the city. He watched the huge stone that had been erected in the center of Lianchuan suddenly disappear, his face full of indescribable surprise.

I'm wondering whether it's two chapters a day for more than 2,000, or a chapter of 3,000 plus 4,000.
