It has been half a year since we arrived at Sunset Valley. In the past six months, Sunset Pass has already had a general prototype, and has first seen its scale, and has played its role, intercepting many scouts sent to the south by the Northern Alliance, which made the Northern Tribal Alliance hate it. So he sent a small number of troops to harass him. As a result, before he could see the valley camp, Robben commanded a newly established independent artillery regiment to use 100 Type 75 mountain cannons to hit a fallen flower and water. At this point, the Northern Alliance has never sent anyone to harass the construction of Sunset Pass again.

The northern tribe did not come, and Robben was happy to be idle. His main task now is to integrate all the troops of the Thunder Tribe. He divided the 70,000 Thunder Tribe Legion into three naval, army and air force: the navy is tentatively 2,000, and there are two warships. The Victory and the new warship launched by Robben named Raiders not long ago. There are 1,500 sailors, 500 reserve sailors and an ironclad ship under study, with a total combat power of 2,000; the Army

It was the main force of the Thunder Tribe. There were 3,000 Thunder Legion, 5,000 City Defense Battalion and 500 Bear Knights. Later, 150 machine gun squadrons were formed, 300 independent Type 75 Mountain Cannon Battalion and Robben's own guards totaled 10,000 people. Later, when Robben went out to fight, a new 50,000 legion was formed to participate in training. Now, basically completing basic training, Robben incorporated all these people into the Thunder Legion and re-divided the Thunder Legion.

The reorganized Thunder Legion had a total strength of 50,000, and five infantry regiments, one directly under the corps, and one directly under the mixed machine infantry regiment. Each of the five infantry regiments was equipped with 9,000 people in each regiment, and the artillery regiment was equipped with 200 Type 75 mountain cannons. In addition, each artillery squad was equipped with a machine gun group and a support force of 1,000 people. The mixed machine infantry regiment was divided into two parts, one part was 500 directly under Robben to protect Robben's safety. The other 1,500 people were equipped with a machine gun for each three, and became a machine gun group, supplemented by rifles, grenades and other self-defense weapons. Since then, the Thunder Legion has been organized in an all-organized system, and a new army will still be formed according to this organization.

After this period of development, the Air Force has 3,000 goblin fighters and has completed 600 bee-type fighters. In the process of intensifying training, Robben plans to divide the Air Force into two parts: one is the garrison air force stationed in tribal camps, and the other is the Expeditionary Air Force that can sail far away on Kirov airships. Because of the difficulty in making Kirov airships, Robben plans to build two ships first, and all of them are the garrison air force defense stations.

In addition, because the Sunset Pass is being built recently, military defense is also required, Robben has drawn 10,000 veterans from the Thunder Tribe and re-enlisted 20,000 new recruits to form the Sunset Legion guarding Sunset Pass. In addition, 30,000 were drawn from the Shanghai God Tribe. By then, when the Sunset Pass is built, the Sunset Legion can reach a scale of 60,000. Robben has also specially formed an independent artillery regiment, an independent machine gun regiment, and a thousand air force garrisons for the Sunset Legion in advance. After the Sunset Legion is officially completed, it can have strong fire support and air force.

After 100,000 people working day and night, and the Thunder Tribe and the Sea God Tribe are given priority, after more than half a year of emergency repairs, the main city wall of the Sunset Pass was initially built. The Sunset Pass was built into a double-layer city wall adjacent to the moat. The inner wall is composed of a solid structure, with a wall thickness of 5 meters and a height of 12 meters. The exterior is carefully cut limestone blocks, and the core of the city wall is stucco made of limes and rocks crushed. There are about seven to eleven brick belts across the structure, each of which is about 40 cm thick. These brick belts are not only used as decoration, but also strengthen the cohesion of the structure by tightening the rock surface and the core, and can enhance the resistance of the city wall to natural disasters such as earthquakes.

The city wall of Sunset Pass has 16 towers, including four towers on the front and back. Four towers were built on the ridges on both sides, supplemented by city walls, which avoided enemy troops climbing up to capture the pass. These towers were mainly square, 18-20 meters high, and the spacing of the towers was at least 50 meters. There were battlements on the top of each tower, and there were spaces for mountain cannon shooting and battlements dedicated to machine gun shooting. The inside part of the tower was two floors, the bottom floor led to the city and used as storage. The upper floor could enter through the city wall walkway, with windows for viewing and projecting. You can use an inclined ladder to climb the city wall. However, due to the progress of the project, all towers had not started construction. That was the second phase of the project after the city wall was completed.

The distance between the exterior wall and the inner wall is 15-20 meters, and the gap between the two walls is called the inner city platform. The bottom of the exterior wall is 2 meters thick, and there are some arched rooms connecting the outer city platform. Above is a battlement walkway, and the outer wall is about 8.5 meters high. From the city, you can reach the outer wall through the main city gate or the back of the bottom floor of the inner wall. There are also 16 city towers in the exterior wall, which are round and just in the middle of the distance between the inner wall towers, playing the role of assisting the inner wall tower. The room connecting the outer city platform has windows and a back door below to the outer platform. The defense of the exterior wall is amazing, and Robben personally tried to directly withstand the bombardment of the Type 75 mountain cannon.

The distance between the moat and the exterior wall is about 15 meters, forming an outer city platform. The inner city platform has a road extending along the city wall. The moat is 20 meters wide and has a water depth of 10 meters. There is a wall on the inside of the river that is 1.5 meters high and has a shooting port. This is regarded as the first line of defense at Sunset Pass.

There are eight main city gates and sixteen side gates in the city wall. Some main city gates can lead to the moat. The secondary side gates are called common city gates, which can be used by the army during wartime and can lead directly outside the city wall. It is worth noting that this side gate is divided into military and civilian. These secondary city gates are also used for civil transportation in normal times. The distinction between civilian and military city gates was actually proposed by Robben. He was worried that civilian materials would block the wartime passages when war broke out, so he divided the two. Among them, the city gate located in the middle of the Sunset Pass was used as the main city gate of the Sunset Pass. A glorious main city tower was built on the wall above the main city gate. A horizontal plaque was hung on the city tower with five big words "The First Pass in the World" written on it, making the front of the Sunset Pass look majestic and dignified.

In addition, Robben personally designed multiple fortifications and prepared to start construction of the second phase of the project after the main body of the city wall is completed. It can be said that it forms a comprehensive defense system with the city wall. The earliest and largest scale is the acropolis about 20 kilometers long. As the outer defense of the Sunset Pass, it is located 3 kilometers north of the pass and surrounded the Sunset Pass. The acropolis wall is 3 meters thick and 5 meters high. Its main function is to serve as an auxiliary defense pass. When the enemy suddenly attacks, it can delay the enemy's attack and give the inner pass to reflect the defense time.

In the open space between the Acropolis wall and the Sunset Pass, Robben planned a large area of ​​neat farmland and two fortresses. Usually, farmland could provide food for Sunset Pass. The two fortresses were guarding both sides of the northern passage, one left and one right. Both fortresses Robben put in great effort. The outside armed ones were like hedgehogs, all of which were guns and guns. In the future, tunnels would be dug from the underground to connect the fortress and the main city. In this way, even if the entire Acropolis fell, these two fortresses might not be captured. These are the necessary paths to Sunset Pass. They are considered to be the external defense area of ​​Sunset Pass, which is used to protect the main city, gather troops, resettle refugees, and fight against enemy invasions, etc., and can even delay the enemy's attack time.
