After this battle, the battle for Rising Sun City became a focus.

The long-term offensive and defensive game has made the battle for Rising Sun City full of wisdom.

Speaking of this Rising Sun City, the main defenses are naturally the city walls, moats, city towers, and urns, and then there are probably not many.

But in fact, in terms of details, a complete city system must have many other civil engineering facilities.

The earliest human city walls were made of rammed earth, and later they were used to build the city walls in large quantities. This was probably because the bricks at that time were not ideal in terms of cost, performance, etc., and they could not be used for large areas. They often had to face impact on the city walls. Brick-built city walls were not common, and the large-scale use was still rammed city walls. The city walls built with lime, sand and clay were also extremely strong.

Later, this city wall was adopted by practitioners, and it became more and more important and the technical level became higher and higher.

In addition, in terms of city gate style, the first one was a large lintel-shaped city gate hole, and then an arched structure, which is mainly due to cost and strength.

The Asura world has long been widely used to protect itself. Sun Rising City is surrounded by moats connected to the valley water outside the city, and it is extremely wide.

This moat is almost the basic equipment of the city. It is not only used for defense, but also often one of the water sources in the city. As for letting the enemy run directly to attack the city, any guard with a little bit of mind will probably not be happy.

Of course, in terms of the details of the moat, there are some differences between cities. For example, in order to facilitate access and infrequent wars, some large cities may not use suspension bridges but fixed wooden bridges outside the main gates of some large cities.

Some even cut off the moat outside the main city gates, using only ducts to connect the river water on both sides, but in this case, they generally do not give up their attention to urban defense completely.

There is a mechanism called "Fengliang" that starts after the enemy is on the bridge, and the result will be that the bridge deck will be tilted and flipped, lifting the enemy into the trench.

In the Asura realm, two short walls are often built forward on both sides of the city gate. There are wide high platforms at the front and even horn towers on it. This is called the "city gate". Together with the city gate, the city gate forms a three-sided attack situation to strengthen the protection of the city gate.

This kind of protective measures is even more necessary outside the gate without a moat. Buildings like the city gates use it as a helper to defend the city in wartime, rather than just a decoration.

In addition, there are some special designs in the wall structure of Rising Sun City, which fully consider the defense operations under various conditions, and have been developed very comprehensively in the future.

Jue Cave is a night lighting facility to prevent the enemy from climbing the city while taking advantage of the darkness. She also considered how she could not shake the eyes of the soldiers guarding the city while illuminating the enemy.

and

The hanging door is a secret door located in the city gateway, which is lifted and lowered by a winch. This is obviously less easy to open than an ordinary city gate that is open in a crossover, but it is easy to close.

In many tactics of luring enemies, it is used to cut off the retreat of the enemy entering the city and then eliminate it.

Horse faces are gradually being promoted, but they have actually appeared for a long time, but they were not fixed as square at that time, but were horseshoe-shaped, either directly convex to the outside of the wall or built on the outside of the city wall.

This is a very necessary city defense project, because without it, the crossbows of the soldiers guarding the city can only shoot at enemies that are a certain distance away from the city, and cannot attack the enemies that are stuck at the foot of the city.

This will become a very deadly dead corner. The optimal distance between the horse face is basically equivalent to the effective range of the crossbow at that time, because this can cover each other and eliminate the dead corners on the outside of the horse face.

There is another way to eliminate the dead corners under the city. It is the seating building designed by the Mohist school in the Warring States Period, a wooden building that was picked out outside the city wall. They also designed a movable slab house called "Hunting the Gentle" which was installed on the outer edge of the city wall. They used winches to control the lifting and lowering along the outer wall, carrying soldiers inside, and attacking the enemies who climbed and attacked the city.

Sometimes such side firepower is not enough, so people build a high platform at a certain distance outside the city wall, with crossbows built on it, and only rope ladders can go up and store certain weapons and food.

This can threaten the back of the enemy, which is a very effective reverse firepower, and this is equivalent to increasing the defense depth. Another way to increase the defense depth is to build a sheep and horse wall between the moat and the city wall, a low wall with a squat and perforation.

Inside the city wall, the city defense should also be considered. In addition to the often seen stairs and ramps, a loop should be built next to the city wall so that the defenders can quickly maneuver and transport equipment. If there is any loop congestion during the battle, please slow down and drive slowly, which will be fatal.

Due to the limitations of cost and project volume, it is indeed difficult to achieve good results in civil engineering such as city walls.

However, it was a pity that Luohu's side did not consider the basic moat and horse face when renovating and building Xuricheng.

In terms of various equipment and tactics of attacking and defensive cities, the realistic effect should be easy to pursue.

Cloud ladders are probably the most commonly heard siege equipment, but they are not something that looks like a bamboo ladder. Using that simple tool to siege the city was called "ant-attached" and "moth tutor" in ancient times, which was a relatively helpless method of siege.

For example, they are often equipped with a pair of small wheels on their heads, so that they push forward hard after reaching the city wall, so that the small wheels can roll along the wall and stand up quickly. Or they can directly tie a crossbar to a long bamboo pole and a wooden pillar to form a lighter bamboo ladder.

The ladder that the ancients generally called was a large siege equipment with wheels at the bottom, and soldiers were pushing forward under the ladder.

It is said that Lu Ban invented it, but it must have been there during the Warring States Period.

Now, an upper city staircase has been added to the main staircase, and the first two wheels are installed on the ladder. With the advancement of wood processing technology, a folding mechanism and protective device have been added to the ladder.

Of course, if this kind of ladder wants to approach the city wall, it must first cross the moat and block the trench.

The "shou" in the siege method is to use earth, stone, firewood and firewood to fill the trenches and open up channels for the siege.

It is not a good idea to rely solely on manpower to carry it on your back. Therefore, a kind of toad cart appeared during the Southern and Northern Dynasties. After loading soil, it was pushed over and stuffed. Historical books even recorded large toad carts promoted by 300 people.

If people only need to cross the trench, the directors like to let soldiers cross the river by stepping on bamboo ladders, which is probably influenced by the People's Liberation Army. In fact, during the Warring States Period, there was a bridge specifically crossing the trench, and there were two wheels below to facilitate movement, called flying bridges. Later, there were trench bridges and slitting bridges, which were more convenient for personnel to pass quickly.

When approaching the city wall, in addition to climbing through a ladder, the attacking side will also use a rushing car to hit the city gate. This tactic is called a rushing car. However, in addition to the city gate, a rushing car also directly hits the city wall, destroying its rammed earth structure and causing the city wall to collapse.

During the second siege, he led tens of thousands of people to attack, while Luohu only led 3,000 people to defend.

When the ladder was rushing to the city, Luohu used rockets to burn the ladder, and used a rocket hanging from ropes to press the ladder, breaking the strategy of how to attack the city.

Later, there was a special collision, which could move around the city, wrap iron at the front end of the collision wood, hit the siege ladder, and the stone mill was replaced with a special iron collision wood, made of heavy wood into a bell shape, and an iron blade was installed around the lower edge, and then it fell down and smashed the rusher.

The fire is mostly in the ladder. After the failure of the rushing car, high-rise wooden frames are built, and the defenders at the city are suppressed with bows and arrows, and then the trench is filled with soil and directly fill it to the city.

The Luohu army built another city wall in the city. Wu Feng then dug a tunnel to lead directly into the city, and dug a trench horizontally in the city.

In this way, I attacked for many days and days, but still couldn't break through the Rising Sun City.

Because these methods of siege were adopted during the war of Asura Emperor, the ancients had come up with countermeasures.

Of course, the Yanhuo Army's methods of siege are not only exposed. The Yanhuo side thinks this is too slow, and can use siege, large shield and other equipment to cover the soldiers to get close to the city wall and then attack. The defender will use stone mills to smash them, and the attacker will strengthen the strength of the siege, and later changed it to a spire, called a pointed wooden donkey. Therefore, the offensive and defensive sides develop each other in this constant confrontation.
