"Eagles of Iyo, take up your weapons and fight with me." Nelson drew his sword, the eagle emblem shining on his shoulder.

Like the other forces in the Allied forces, the nation of Aiyo captured Fort Michod and used the castle as a military garrison, in which the entire strength of Aiyo was stationed.

Ten minutes earlier, Iyo had received a warning message from the Metal Dragon of Fort Grana, and five minutes earlier, they had observed Monet's army at the end of the vault in the midst of a tidal wave.

Now, Monet's monsters have reached the range of the strike.

"Spellcaster!"

Without the king's and commander's orders, the senior mages raised by the royal family of Iyo had already begun to prepare, and the swarming femme fatales had just stepped into the strike range, fireballs, ice picks, wind blades, and rock studds struck like a storm, and the green blood of the femme fatales splashed high, and the stumps and scraps of flesh were heavily thrown on the bodies of their companions, and they roared, and kept approaching Fort Michod.

"Spear, spear!"

Crossbow spears and spears whizzed by, pinning a massive number of femme fatales to the ground, not enough to kill them in a short period of time, but the time limit of their inactivity was enough to crush them to the ground by a succession of monsters behind them.

In addition to arrows and spears, some watchtowers also flickered from time to time, and after a series of aid deals with the Blackwing Empire, the Aeyo Kingdom received a lot of industrial weapons from the north, muskets shine in defensive battles, and more importantly, those swarthy heavy artillery, rolling stone-like cannonballs can cause magic as much damage, or even stronger.

Before this, the low level of magic guide country can only import magic guide cannon to the trade city-state, but because its cost is too expensive, even if the power of a country is exhausted, the country of ai can not assemble that kind of strategic weapon for each army, in fact, this is not bad in comparison, I heard that it has been reduced to the history of the northern countries, back then there were less than five magic guide cannons in the whole territory, it is said that they don't need this thing, and the result was destroyed by the Black Dragon Emperor.

If you compare the magic cannon with the Black Wing heavy cannon at the same level, of course, the magic cannon is fully crushed, and the magic cannon that integrates the peak of magic guide technology is more powerful, has a longer range, is easy to carry, and does not need to be loaded, these characteristics make it still the king of land weapons in Eladia today hundreds of years after its launch.

However, the high cost of the cannon is prohibitive for small countries, and many countries will not assemble their armies in large quantities even if they can afford them, because the magic cannon must be maintained by a team of mages who are proficient in magic technology, and the amount of money to support this team every year is an astronomical amount of money - this thing is a bottomless black hole to use.

The Black Wing Heavy Artillery is different, the price is its biggest advantage, not to mention that the Black Wing Heavy Artillery is also very powerful, Nelson received information that the Buchi Kingdom has done experiments, and the strike power provided by five Black Wing Heavy Artillery is basically comparable to a magic cannon, and considering the range, portability, etc., eight Black Wing Heavy Artillery can be completely compared with a magic cannon.

The most important thing is that the Northern Empire will provide supporting services for the countries and forces that purchase the Blackwing Heavy Artillery, and the one-time purchase of fifty Blackwing Heavy Cannons will come with a team of cannons, and even if some small forces have insufficient purchasing power, they can go to the Northern Empire to recruit craftsmen who maintain the Blackwing Heavy Cannon.

It is said that these craftsmen, who were awarded qualification badges by the Black Wing Empire, all came from a place called the "Imperial Academy". Nelson knew that those were ordinary people, and that the salary they needed to support was only as much as the pay to hire a knight.

This is undoubtedly good news for the northern countries, and after the news gradually spreads in recent years, most of the countries that trade with the Black Wing have begun to replace this heavy artillery in batches.

In fact, after two years of research, there are also workshops in the Iyosala region that can make imitation black-winged heavy cannons at a lower price, but countries still tend to import this weapon in bulk to the Northern Empire, firstly, the quality of the two is different, and some imitation black-winged heavy cannons are heard to explode when firing; Second, it is mainly to buy the maintenance team of the Northern Empire, and provide return and replacement services for the Heavy Artillery Empire with serious problems, and some faults that cannot be handled by local craftsmen can also be sent to the Empire for repair.

Third, the purchase of the Black Wing heavy artillery is, in a sense, also a purchase guarantee. This point will not be discussed in depth, and countries will not put it on the surface.

Fort Michod has fifty black-winged heavy cannons, when the enemy is put into the maximum kill area, these heavy cannons fire in unison in a roar, the scene is undoubtedly shocking, like a muffled thunder exploding on the city wall, solid iron balls with sparks gushing out, smashing into the enemy group, crushing lives with unstoppable force, plowing out one blood after another.

The nation of Aiyo suppressed the monsters with absolute firepower, but just when Nelson felt that he had won the battle, a new ocean appeared on the other side of the earth.

The Kuroshio spread across the horizon, and the long tails of the second group of monsters were twisted together, and the scales glowed with the same light as metal, and they kept wriggling, rapidly approaching at several times the speed of the femme fatales and Nayu spiders, and under the monitoring of the mage's eye, these creatures were like a group of snakes entangled **, but with dragon-like heads and sharp teeth.

Viper.

Nelson's hand trembled, and he gripped the hilt of his sword tightly.

In the analysis of the metal dragons, the vipers are Monet's main combat force, they are as strong as dragons, with hard scales and powerful strength, and these are the vipers that have been refined by the Queldore technology, complete machines.

"Retreat." He squeezed out a word halfway.

"Your Majesty, let's defend ...... quickly"

The commander turned his head to look at him, and at the moment when his eyes were pulled, he saw the vipers surging like a black tide, and quickly glanced at the mage's eyes, thought for a while, and then changed his words, "Your Majesty, the Blackwing Empire promised them to deal with the vipers, I think the empire should have observed the viper swarm before us, as long as we hold on to ...... longer"

"Do you want all my soldiers to die here? I say, retreat! ”

Nelson took a deep breath and interrupted him, as if he had made up his mind, and said at a very fast pace, "This is not a disobedience, we have not received an order to hold on in the face of a strong enemy, and the viper dragon can only be resisted by the Blackwing Empire, quickly, quickly!" Evacuate in batches while there's still time to use the teleportation array! ”

"Yes, Your Majesty!" The commander also said quickly, "Do you need to ...... first?"

"Can't you understand what I'm saying? Casa! Let the troops close to the teleportation array go first. Watching the viper tide get closer and closer, Nelson's words almost roared.

"Fort Namichod and these heavy artillery ......"

"You can't take it away and give up!" Nelson forcibly took over command and ordered the troops to leave.

Soon, as Fort Michod's firepower weakened, some femme fatales gradually climbed the city walls, and the distance between the vipers and the group of vipers was rapidly closing, and they could already see the figures walking on the walls with the naked eye, letting out a sharp scream like a woman.

"Casa, let's go." Nelson stabbed the femme fatale in the chest with a sword, and the king's guards quickly filled the gap.

"Your Majesty......"

"Damn, don't you understand me?" Nelson suddenly kicked the commander without the demeanor of a king, kicking him towards the teleportation array, "Get out!" ”

Seeing that Casa also poured into the teleportation array with a force, Nelson's tense face covered with sweat slackened, there was still plenty of time, the peater arrived not as fast as he expected, he took a breath, and said to the only remaining guards on the city wall and the king's personal guard, "Okay, we are ready to ...... too"

Before he could finish speaking, the walls shook violently.
