"Aiyo eagles, take up your weapons and fight with me." Nelson pulled out his sword and the eagle badge glittered on his shoulder.


    Like other forces in the Allied forces, aiyo captured Michaud castle and took the castle as a military station, in which aiyo''s all forces were stationed.


    Ten minutes ago, aiyo received a warning message from the metal dragon of dagrana fort. Five minutes ago, they stationed in Michaud Fort observed that Monet''s army appeared at the end of the sky like a sea tide.


    Now, Monet''s monsters have reached the attack range.


    "Caster!"


    Without the order of the king and the commander, the senior mages kept by the Aiyo royal family have already begun to prepare. The swarming snakes and scorpions have just entered the attack range. Fireballs, ice cones, wind blades and rock outbursts hit like a storm. The green blood of snakes and scorpions splashed high, and the stumps and broken meat were thrown on the bodies of their companions. They roared, Keep approaching michaudburg.


    "Yu, spear!"


    The crossbow gun and throwing spear swished past, nailing a huge snake and scorpion servant to the ground. Such damage can''t make them die in a short time, but the limited time of being unable to move is enough to make them trample into meat and mud by the monsters coming from behind.


    In addition to arrows and shotguns, some watchtowers also flickered from time to time. After reaching a series of aid transactions with the black wing Empire, aiyo received a lot of industrial weapons from the north. Guns shine brightly in the defensive war, and more importantly, those dark heavy guns and rolling stone shells can cause magical lethality and even stronger.


    Before that, the aiyo country with low level of magic guide could only import magic guide guns from the trading city states. However, because its cost was too expensive, even if the strength of one country was exhausted, the aiyo country could not assemble that kind of strategic weapons for each army. In fact, this was still good. It was said that the northern countries, which have become history, had less than five magic guide guns in the whole territory in those years, It is said that they didn''t need this thing, but they were destroyed by the Black Dragon Emperor.


    If you compare the magic guide cannon with the black wing heavy cannon on the same level, of course, the magic guide cannon is fully rolled. The magic energy cannon integrating 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 ayladia hundreds of years after its launch.


    However, its high cost makes small countries have to flinch. Even if many countries can afford to buy, they will not assemble a large number of troops, because the magic cannon must be maintained by a team of mages who are proficient in magic guidance technology. You know, the money to support this team every year is also a heavenly figure - this thing is a bottomless black hole.


    The black wing heavy artillery is different. Cheap price is its biggest advantage. Moreover, the power of the black wing heavy artillery is also good. Nelson received information that the butch Kingdom has done experiments. The strike power provided by the five black wing heavy artillery is basically comparable to that of a magic cannon. Considering the range, portability and other characteristics, the eight black wing heavy artillery can be compared with a magic cannon.


    The most important thing is that the northern empire will provide supporting services for countries and forces that buy Black Wing heavy guns. If they buy 50 Black Wing heavy guns at one time, they will give a gun team. Even if some small forces lack purchasing power, they can go to the northern Empire to recruit craftsmen to maintain Black Wing heavy guns.


    It is said that these craftsmen who were awarded qualification badges by the black wing Empire came from a place called "Imperial College". Nelson knew that those were ordinary people, and the salary needed to support them was only equivalent to the salary of hiring a knights.


    This is undoubtedly good news for the countries in the north. In recent years, after the news gradually spread, most countries with trade relations with black wing began to replace this heavy artillery in batches.


    In fact, after two years of research, there are workshops in ayoshala that can make imitation Black Wing heavy guns at a lower price. However, countries still tend to import such weapons in batches from the northern empire. First, the quality of the two is different. Some imitation Black Wing heavy guns are said to explode when firing; Second, it mainly buys the maintenance team of the northern Empire and provides return and replacement services for the heavy artillery empire with serious problems. Some faults that cannot be handled by local craftsmen can also be sent to the Empire for repair.


    Third, the purchase of black wing heavy artillery is also a guarantee in a sense. If this point is not discussed in depth, all countries will not talk about it in the open.


    There are 50 black winged heavy guns in Fort Michaud. When the enemy is placed in the maximum killing area, these heavy guns fire in unison in a roar. The scene is undoubtedly shocking. It is like the roar of thunder exploding on the city wall. Solid iron balls with sparks gush out and smash into the enemy group. They crush life with unstoppable force and plough out blood * * gullies one after another.


    Ayo suppressed the monsters with absolute firepower, but just when Nelson felt that he had the victory, a new ocean appeared on the other side of the earth.


    The black tide covered the horizon. The long tails of the second batch of monsters were twisted together, and their scales were shining like metal. They kept crawling and approached quickly at several times the speed of snakes, scorpions and naiyou spiders. Under the monitoring of the mage''s eye, these creatures were like a group of snakes entangled together, but they had dragon like heads and sharp teeth.


    Viper.


    Nelson''s hand trembled and held the hilt tightly.


    In the analysis of the metal dragon family, Viper dragons are Monet''s main combat power. They are as strong as dragons, with hard scales and powerful power. These Viper dragons are completely machines refined by queldore technology.


    "Retreat." he squeezed out a word after half a ring.


    "Your Majesty, we''ll hold it soon..."


    The commander turned to look at him. At the moment of pulling his eyes, he saw the Viper dragons coming like the black tide. He quickly looked at the mage''s eyes, thought about it, and then changed his words, "Your Majesty, the black wing Empire promised to let them deal with the Viper dragons. I think the Empire should observe the Viper dragons before us, as long as we stick to it..."


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


    Nelson took a deep breath and interrupted him. He seemed determined to say at a very fast speed, "it''s not a violation. We haven''t received the order that we still need to stick to when encountering a strong enemy. Only the black wing empire can resist the Viper dragon. Come on, come on! Evacuate in batches while there''s still time. Use the transmission array!"


    "Yes, your majesty!" said the commander quickly. "Do you need to..."


    "Don''t you understand what I''m saying? Casa! Let the troops close to the transmission array go first." Nelson almost roared as the Viper tide approached.


    "Then Fort Michaud and these heavy guns..."


    "Take it or leave it!" Nelson forcibly took over the command and ordered the troops to leave.


    Soon, as the firepower of Michaud Fort weakened, some snakes and scorpions gradually climbed up the city wall, and the distance between the Viper dragons was also rapidly narrowing. They could see the figures walking on the city wall with their naked eyes and scream like a woman.


    "CASA, go." Nelson stabbed the serpent and scorpion in the chest, and the king''s guard next to him soon filled the gap.


    "Your Majesty..."


    "Damn, don''t you understand me?" Nelson suddenly kicked the commander without king''s manners and kicked him to the transmission array. "Get out!"


    Seeing that Casa also poured into the transmission array with an army, Nelson''s tight face full of sweat relaxed. There was plenty of time. The Viper dragon didn''t arrive as fast as he thought. He took a breath and said to the only guard and King guard on the city wall, "well, we''re ready..."


    Before he finished, the wall shook violently.
