Between the Dragon Empire and the Kingdom of Braavos, there is an Iron Tooth Ridge from west to east, the mountains are steep and rugged, and the north and south spans greatly, and only a Great Rift Valley is the only shortcut for the Dragon Empire to reach the Kingdom of Braavos from the interior.

Normally, many caravans would pass through the Rift Valley to travel between the two places, but now the Rift Valley has long been blockaded by the armies of the Kingdom of Braavos.

The entire Great Rift Valley is 12 kilometers long and no more than 50 meters wide, and if you look down from the sky, you will find that it is a narrow thin line, which is more appropriate than a line of sky.

Such a steep terrain has been a battleground for soldiers since ancient times.

However, the Kingdom of Braavos has built a dangerous city called XX here, which has a kind of momentum that is incomprehensible.

In fact, the army of the Flame Dragon Mother launched a war of aggression against Braavos, only to be stopped by this natural danger, and finally had to spare most of the Iron Tooth Ridge and attack from the other side.

However, Izeh Targaryen the Great is not the Flame Dragon Mother, and the well-trained Red Dragon Legion is not the monster army of the Flame Dragon Mother back then-

They are stronger.

The Northland Alliance has suffered several big losses at the hands of the Dragon King, and the Dorne Fortress can't even resist it for half a day, knowing very well how powerful the Dragon King's army is.

As a result, in the past nine years, the walls of the Iron Castle have been strengthened several times, and the deployment of troops has been optimized again and again, in addition to being equipped with a large number of spellcasters, even the number of elemental towers has been expanded to eight in a narrow terrain of fifty meters.

Therefore, the army of the Braavos Kingdom has ten percent confidence to stop the Red Dragon Legion from the Iron Tooth Ridge, and unless the Iron Fort barrier is broken, the monster army will not want to step into the territory of Braavos from here.

……

After the 300,000 Red Dragon Legion was divided, there were not many clan leaders led by them.

Warwick led 30,000 Red Dragons to temporarily station in front of the Great Rift Valley, this guy has a lot of experience in siege

He had long heard of the name of the Iron Castle Barrier, and it was naturally no ordinary city to be able to keep the monster army of the Flame Dragon Mother out.

Now looking at this precipitous terrain that is easy to defend and difficult to attack, he knows that he will be greeted by a tough battle.

At this time, the Dragon Empire was fighting on multiple fronts, and there may be several battlefields that were fiercely engaged on the vast national border.

As the commander of the Red Dragon Legion, Warwick naturally chose the most difficult bone to gnaw on the Iron Fort and handed it over to the leaders of other clans, he was not at ease.

This licking dog can stay by the Dragon King's side for a long time, and he is undoubtedly very smart, unlike Kane Bloodhoof, who only knows how to go on a rampage.

Therefore, in the face of the iron fortress, he did not rashly launch an attack, but probed all kinds of information in detail.

Only by knowing oneself and knowing one's opponent can one not be defeated.

Two nights later, a drow elf handed over a military document to Warwick, and he did not let anyone find out about it, completing the task assigned by the leader of the Wolf Fangs.

Warwick looked at the map of the fortress defense that Darkscale had stolen from the walls of the Iron Fort, which detailed the distribution of troops, the number of troops, the location of the granary, the armory, the barracks, the distribution of the garrison, and so on.

The iron fortress is twenty-five meters high and thirty meters thick, the number of defenders is only 20,000, and there are 382 spellcasters of various professions, including seventy-eight priests.

However, there were fifteen large catapults, as well as eight elemental towers, twenty artillery pieces, and ten bed crossbows, and this configuration could easily stop the army of 100,000 humans in this first-line terrain.

It is worth mentioning that explosives are not an uncommon thing in this fantasy world.

There are wizards and alchemists who are constantly getting stronger by studying knowledge, and the cannons of this world are even much stronger in power than the modern red-clothed cannons of the world that Izawa knows.

The shells contain not only explosives and shrapnel, but also various spell effects after the explosion.

The only flaw is that the firing frequency is not fast, and it is easy to blow up.

The narrow terrain of the first line of sky is not conducive to the Red Dragon Legion to launch a charge, and once it enters the range of the opponent, it is easy to be attacked by the enemy, and it is impossible to avoid it.

Although the Red Dragon Legion is powerful and can ignore ordinary bows and arrows in iron armor and steel helmets, it cannot withstand the ground-washing attacks of large engineering equipment such as stone throws, bed crossbows, artillery, and elemental towers.

Coupled with the caster's use of large-scale trap spells, such as swamps, glaciers, and confinements, if they rashly attacked, they might have lost most of the 30,000 Red Dragon Legion before they rushed under the walls of the Iron Fortress Barrier.

At that time, the Iron Fort was not captured, but Warwick himself had defeated all the Red Dragon Legions, and he was afraid that he would be severely punished by His Majesty, and he could not afford to lose this person.

Now that he knew the detailed arrangement of the Iron Castle barriers, he could use his advantages to make some arrangements.

For example, one hundred wyverns, one hundred and fifty Chimera, three hundred griffins, three hundred manticores, plus the red dragon Aurelian.

Sister Long felt that staying in the Dragon Palace was too boring, and she didn't want to see those two hateful guys in front of her all day long, coupled with the desire to conquer in the red dragon's blood, so she followed Warwick directly to the front line in a fit of anger.

There is no doubt that this is a force that can completely dominate the air, but today's Red Dragon Clan can be equipped with every clan leader casually.

In addition, there were fifty giants accompanying them, and the brute strength of these big men threw boulders no less than catapults.

So, Warwick learned from the siege experience of previous wars, and spent three days making various pre-battle preparations, making sure to defeat them in the siege battle at once, and he did not have much time and troops to spend here.

To be honest, this guy didn't take the Iron Castle Barrier seriously, after all, even a city-state of the level of Farranlun had been conquered by the iron hooves of the Red Dragon Legion, although His Majesty personally stepped in at that time, but he thought he could do it.

In the eyes of the defenders of the Iron Fortress, the Red Dragon Legion did not seem to have any intention of attacking the city, but was just blindly stationed in front of the Great Rift Valley.

But this guy is very bad, every day at 3 o'clock, 5 o'clock, 8 o'clock, 12 o'clock, 18 o'clock, 24 o'clock, let his wolf cubs blow the horn of the offensive war, and make the defenders of the iron fortress panic.

But every time it blows and doesn't move, it makes the human soldiers who are ready for defense scold, this kind of thing is enough to come once or twice, so many times a day, even an iron man will feel tired.

This continued until late at night, three days later.

The Red Dragon Legion's attack quietly began.
