The mudslide in the heavy rain at Fort Berranie made Andelt feel a little lucky, glad that he was not in a hurry to capture Fort Berranni and let the soldiers of the sun never set escape, but also felt a little more uneasy in his heart, after all, this kind of thing has the first time, it is very likely to happen the third and third times.

Although natural disasters cannot be prevented by humans, there are many facts that prove that natural disasters are most likely caused by man-made. In addition, as a more important city in the Western Regions of the Central Continent that the sun never sets to manage next, if there is a possibility of mudslides in Fort Borranie in the future, it is necessary to be prepared in advance, so after a little contemplation, Andert gathered all the engineers in the general (the engineers of the sun never set can be described as the existence of the army's universal wrench, because they are not only senior repairmen of war equipment, but also senior designers of fortifications, in addition to the gunners, Counterweight trebuchet operators and others had to find weak areas of local buildings on the battlefield, so some of the Sunset Engineers were half-baked geographers and surveyors, hoping to find out through these Sunset Engineers the cause of the disaster that caused the mudslide in Fort Berranni, which had never had a mudslide before.

And it didn't take long for a group of embarrassed Sunset artillery surveyors, that is, Sunset engineers who adjusted the direction of the attack for the artillery, to submit a report, as the first to read this report, Andelt sighed lightly after reading it, and a trace of guilt flashed on his face, because the mudslide this time was completely caused by the artillery of the Sunset.

Fort Berranie is known to be a castle built on the edge of a mountain range, and the interior of the mountain range on which the castle rests was hollowed out after it was built and turned into a part of Fort Berani, a part of the mountain that is hidden within the mountain. Although the inhabitants of Fort Berranni did not have any problems in the process of hollowing out the mountains because of their superior construction skills, humans are not dwarves and gnomes after all, and they do not have the amazing city-building skills of these two races, especially the skills of building the interior of the mountains. Therefore, the completion of the internal construction of the mountain range is also a hidden danger for Fort Beranni.

Of course, the master builder of Mordan, who was the builder and designer of the fortress, also discovered this hidden danger after the hollowing out of Fort Berranni, and he also knew that as the trees around the mountain range grew, the roots of those trees would inevitably destroy the rock structure of the outer surface of the Fort Berranni mountain range, causing the cave to collapse. Therefore, after the completion of the general structure of Fort Berranni, the master of the city of Mordan began to renovate the internal structure of Fort Beranne, which was discovered after the army entered Fort Beranne that day, and was later called a legend in the mountains by the tourism enthusiasts of the King Continent - Boran Mountain City.

The inner area of the Fort Berranni Mountains, transformed by the efforts of the master Mordan before his death, can not only grow foods such as mushrooms, but also grow dark water trees, which can thrive with just a little light and a lot of fresh water. The most important thing is that its roots are magical plants that turn scattered silt into stone (this is where the "top forest" of Fort Berranie comes from, referring to the dark water forests that grow to the fortified tops of the inner mountains of Fort Berranie). And the planting of the Anshui tree also made it possible for this master of Mordan to build a city without the need for a landslide event to occur inside a large mountain range.

In addition, the master builder of Mordan also designed a complete urban canal system for Fort Berani, which extends from the top of the mountain on which Fort Berranie depends, to the interior of the mountain range and the inner and outer cities of Fort Beranni, which can not only solve the problem of water supply in the Fort Berranie Mountains, but also prevent the possibility of mudslides in the mountains.

Of course, the city canal also had its drawbacks: it was impossible to lay pipes inside the mountain, as was the case in later generations. Therefore, part of the urban aqueduct system of Fort Berranie must be exposed to the air if someone deliberately destroys the urban aqueduct system of Fort Berranie. That would be a high risk of mudslides and even flash floods in Burranniburg. After all, although the rainfall in the Western Regions of the Central Continent is not as urgent as the British islands in the original world, it will not be much worse.

As for this problem, the designer, that is, the master of Mordan who designed the castle of Berranni, died before the builders found out about the problem, and at that time, there was no Moldan Imperial City in the Duchy of Moldan but it was controlled by the Principality of Moldan (originally called Slok City, which belonged to the Principality of Mold, and was later renamed Moldan City after the surrounding principalities merged into the Kingdom of Moldan). As for what is named after the Mordans, because the Moldans who own Fort Berranni are the most powerful of all the principalities in the merger).

At the end of the day, many of the Moldan's craftsmen had to solve the problem by modifying part of the original urban aqueduct area, including laying the urban aqueduct on the surface of the mountain behind the main castle of Berranny and under the three megalithic walls: the former was due to the builders. Generally no trebuchet can hit there, and no one will throw stones at the rear for no reason, and the latter, although it seems dangerous, and is always exposed to the enemy's noses, but as the walls continue to widen and heighten, and the stones taken by the walls are made of huge stones made of extremely hard and huge granite polished from the vicinity of Burranie Castle, so as long as the walls are hidden behind the walls and inside the city walls, there will be no damage. And the most important thing is that if you want to destroy the city canal system in the city wall stage, you must destroy one of the three walls of the castle in Beranne, and even if the urban canal system in the city wall section of the city wall is destroyed, it does not matter, because at the beginning of the design, the master builder of the city said that it is useless unless the two main systems of the city canal system are destroyed.

It is also because of the stability of the urban canal system that the Moldanes, especially those who were born and raised in Burranniburg, know how to repair the city walls and those urban canal systems every few years, but they gradually forget the fragility of the urban canal system of Burranniburg.

And the sun never sets is actually unknown, including now that Andert has received the information from those sunset gunners. However, the soldiers knew that if they wanted their troops to advance to the inner city of Fort Berranni as quickly as possible when launching a general attack, and even the inner area of the mountain range of this fortress, the most effective, direct and fastest way was to destroy the city walls, which made the artillery units of Sunset destroy the urban aqueduct system located under the city walls of Fort Berranni by mistake; As for the urban aqueduct system located on the mountain range behind the main fort of Fort Berranni, in fact, the sun never sets itself does not want to hit the cannonballs there, but the problem is that everyone knows that the early artillery of the road, especially the heavy siege artillery, which is a thermal weapon that enhances its power at the expense of accuracy, will always give you a "miss" wherever you want to hit, so many cannonballs flew towards and hit the urban aqueduct system located on the mountain behind the main fort of Fort Berranni.

In the case of the destruction of the urban canal system that originally served as a flood control system, the rainwater could not continue to flow into the interior of the Borranniburg Mountains called civil water, but flowed down the slopes, and the surface of the mountain range was often blown by high-level air currents, resulting in weathering of many mud and rocks, and it is strange that this heavy rain does not become a mudslide when washed down. However, it is worth mentioning that the Sunset Gunners did not report that they accidentally hit the urban aqueduct system of Fort Berranie, but that they accidentally disrupted the rock formations above Fort Beranne, causing the falling rainwater to accumulate on it and eventually form a mudslide.

"So this mudslide was caused by artillery? If that's the case, it's good to say, anyway, although there are not many master craftsmen in our great empire, it would be good to transform the surface of the mountain range. After putting the report in his hand aside, while Andrit himself was muttering to himself, a herald ran up to Andrête and shouted: "Your Excellency, Commander, something has happened in front of the barracks!" ”

"What's the matter?" Endelt frowned.

"That's right, just now after the mudslide at Fort Berranie had almost weakened, and the rain in the sky had also lightened, the gates of Fort Berranni suddenly opened, and an officer of Borani with a white flag in his hand rode to our barracks, and now he has been caught by our soldiers who never set Sun, but he keeps shouting to see you."

"White flags? Surrender? See me? Strange, is something going on at Fort Berranni? With a stomach full of doubts, Andert and the herald of Sunset came to a tent, and met the Mordan officer, who had been standing there even though his body was tied, surrounded by several members of the Sunset General's Guard, with a white flag on the belt around his waist.

At this time, the officer in front of him not only exuded the smell of mud all the time, but also his body, hair and combat boots were covered with yellow mud, and according to several members of the general guard who never set, this guy was not wearing a weapon when he came, and his clothes were the inlaid armor on his body, from this person, it can be seen that this guy is obviously a Mordan officer who survived the mudslide.

And looking at this Mordan officer, there was not an anxious look in his eyes, coupled with the current situation in Fort Berranie, in fact. By this time, Andrette had already guessed most of the reasons for the surrender of the defenders in Fort Berranni. (To be continued.) For mobile phone users, please go to read. )
