A few rays of sunshine passed through the thick clouds indifferently, and sprinkled like light dust on the white snowfield, and on the north wall of Avalon Fortress.

Unexpectedly, the biting winter wind swept through the ice and snow and blew over the city wall, blowing the thousands of flags standing on the city wall.

Su Cheng was standing on the outer wall of the north wall of Avalon Fortress, with his right hand resting on the wall stacks, looking across the wall stacks to the north of the fortress.

Willy, Deng Jiaer, Alyssa, and 16 knights, including 4 military commanders, were all waiting quietly behind Su Cheng.

All the knights of the Michael Knights are here now.

After meeting with the knights of the Michael Knights and saying hello briefly, Su Cheng took all the knights of the group and began to inspect the Avalon Fortress.

Su Cheng's current identity is the Knights of Michael and the top leader of the Northern Front.

In other words, in addition to being responsible for the management and construction of the Michael Knights, Su Cheng also shoulders the heavy responsibility of building and maintaining the northern front.

As the most important fortress on the Northern Front and the most advanced position on the Northern Front, Su Cheng naturally had a need to inspect the fortress.

Avalon Fortress has only two entrances, the south gate and the north gate.

The south gate is mainly used to receive supplies from the rear, and the north gate is mainly used to leave an opening so that the empire can send its army to the northern expedition to the Holy Hiran Empire.

Avalon Fortress is an important fortress located in the southern half of the Eghar Corridor, at the northernmost point of the Britannia Empire, and is specially designed to protect against the Holy Hiran Empire.

Because Avalon Fortress was so important, when the fourth emperor ordered the construction of Avalon Fortress, he recruited 500,000 civilians and gathered the best craftsmen in the country at that time.

After the craftsmen's measurements, they selected a very ideal location in a narrow area of ​​the Eghar Corridor to build the fortress.

This narrow place is no more than 4,000 meters from east to west.

Therefore, the craftsmen built the north wall of Avalon Fortress very long, and the length of the north wall of Avalon Fortress was more than 4,000 meters.

In other words, the craftsmen made the north wall of the fortress connect the east and west ends, which is equivalent to building a large wall in the Eghar Corridor that divides the corridor into two halves.

This design of the craftsmen means that if the Holy Hiran Empire intends to go south to attack the Britannia Empire, it can only attack the northern wall of Avalon Fortress.

As for the Britannia Empire, they can concentrate their forces on the northern city wall and don't have to worry about the other walls being attacked by the enemy, because the Holy Hiran Empire needs to break through the Eghar Corridor into two halves, the north and the south.

Only from the north wall can you see the walls in other directions of the fortress.

This design of the craftsmen is extremely disgusting. Because it can only attack one wall of the fortress, no matter how many troops the Holy Hiran Empire has, the troops cannot spread out and cannot take advantage of the strength.

The Daniya Empire was able to concentrate its forces and energy on the northern city wall.

And this is not the most disgusting part of Avalon Fortress.

The most disgusting thing about Avalon Fortress is that its north wall is a double wall structure!

Avalon Fortress has two inner and outer walls, both of which are made of carefully cut limestone.

There are 8 brick strips across the structure, each brick strip is about 0.4 meters thick. In addition to being used for decoration, the main purpose of these brick strips is to enhance the cohesion of the structure by tightening the rock face and core, and

Increase the wall's resistance to earthquakes.

The inner city wall is 5 meters thick and 12 meters high. There are 80 octagonal towers, each tower is 20 meters high, and the distance between towers is 50 meters.

There are battlements on the top of each tower for archers to shoot and to watch the enemy.

In addition to the inner city wall, there is an outer city wall.

The distance between the outer city wall and the inner city wall is 15-20 meters, and the gap between the two walls is called the outer city platform.

The outer city wall is about 8.5 meters high and also has 80 octagonal towers, which are exactly in the middle of the distance between the inner city wall towers and play a role in assisting the inner city wall towers.

Of course, having two city walls is not the most disgusting thing, there are even more disgusting things.

What's even more disgusting is that there is a moat outside the outer city wall!

There is an artificial moat 15 meters outside the outer city wall.

The moat is 20 meters wide and 10 meters deep.

This moat was originally filled with clear water, but as time went by, it slowly turned into a stinky ditch emitting a foul odor.

A 20-meter-wide moat, coupled with two city walls, just a cursory thought, one can imagine how desperate the Hiran army would be when they attacked Avalon Fortress.

To attack the Avalon Fortress, you must first endure the overwhelming stench and fill up this stinking ditch that is 20 meters wide and 10 meters deep.

When you fill this stinky ditch, the Britannian soldiers on the two walls will continue to shoot you with crossbows.

After you have filled up this stinking ditch with huge casualties, the battle against Avalon Fortress has just begun. You still have to attack the northern wall of Avalon Fortress designed with double walls.

The crossbowmen will stand on the higher inner city wall and use their crossbows to shoot at you from above.

In addition to the crossbowmen, there are also a large number of catapults and siege crossbows set up on the inner city walls. They will not only shoot you with arrows, but also use catapults and siege crossbows to shoot you.

The outer city wall will be filled with melee infantry, who will use rolling stones, wood, and boiling water to attack all enemies who attempt to climb the wall, and fight hand-to-hand with all those who climb the wall.

Under such a three-dimensional attack, the number of casualties suffered by Xilan's army will be extremely shocking.

Even though the soldiers of Xilan Army suffered heavy casualties and with a little bit of luck, they successfully breached the outer city wall.

There is also a higher inner city wall waiting for you!

Therefore, thanks to this northern city wall that combines the wisdom of craftsmen and the blood and sweat of civilians, the Avalon Fortress has never been breached by the Hiran Army since its construction!

The Fortress of Avalon firmly blocked the Hiran people from the fortress and the empire.

…

Su Cheng, who was standing on the outer wall of the northern city wall of Avalon Fortress, touched the battlements made of hard limestone under his right hand. He looked across the battlements at Su Cheng in the far north, and couldn't help but feel a little pride in his heart.

.

Although before he became a knight, when he was still living in Mr. Falk's mansion, Su Cheng had already learned through books that the north wall of Avalon Fortress was a very remarkable wall, and it was a collection of these

The walls of all architectural wisdom of the ages.

Although he had been mentally prepared, Su Cheng was still shocked by the power of the North City Wall after actually arriving at Avalon Fortress and standing on the North City Wall.

"What an incredible city wall..."

Su Cheng couldn't help but sigh.

"If I were asked to attack the Avalon Fortress, I would never go to war if I didn't have 10 times the strength of the fortress defenders under my command."

After saying this in a half-joking tone, Su Cheng turned around and left, heading towards the city wall.

Su Cheng's time was very tight. In addition to the north wall, there were many places in the fortress waiting for Su Cheng to inspect.

In Su Cheng's eyes, there was something in this fortress that was far more important than the north wall.
