"Do I need to go into retreat for almost a year?"

Zhou Yue was a little regretful, in fact, he really hoped that Cai Yan could continue to break through, although she was just a legendary strategist and did not have the strength to fight alone, but for the army to fight, she had a huge advantage.

"It's okay, Sister Yan, you don't have to worry, we will definitely win this battle, although the Mongols are the invincible kings of the grassland, but if you want to conquer the city of the White Tiger you built, it is simply impossible, I think, as long as we win this battle, we will be able to have a buffer for a period of time, and by then you will be in retreat, to be honest, I am already very eager to see Sister Yan, your advanced quasi-epic strategist."

Zhou Yue persuaded quite cheerfully, and he was really confident now, because preparations for this crucial battle had been started a few months ago, and all kinds of materials could be described as piling up.

Among them, it is regarded as the sharpest artifact - the Heaven Interception War Crossbow, which has now produced 1,500 units, this thing can fire 30 giant spears at a time, if 1,500 Heaven Breaking War Crossbows are fired at the same time, what a scene it will be! This is the best means to deal with the large-scale air raid forces of the Mongols, and as many desert wolves and eagles come to them, they will kill as many as they come.

In addition to the special equipment of this Sky Interception Battle Crossbow, the number of ordinary city defense equipment is extremely large, taking the catapult as an example, in the case of the addition of Momen disciples, now this catapult has undergone three improvements, not only the range is longer, the power is greater, the speed is faster, and it is also more durable and durable, such three improved catapults, at present, the City of the White Tiger has a reserve of a full 10,000 units!

The semi-finished materials for the continuous production of zuò catapults can also continue to be assembled more than 10,000 units in the future, which basically avoids the situation that the catapult is damaged and there is no replacement.

Speaking of which, the special wood needed to make these catapults is also thanks to the wolf king Qiaoduo's Jinzhou Black City, because the wolf king Qiaoduo got the giant tree seeds from the elves, the Jinzhou Black City has been turned into a primeval forest for a hundred miles, this is not an ordinary forest, but a forest with magic, not only not afraid of forest fires, but also in the cold winter, can be lush and vibrant.

This primeval forest has not only become the habitat of the werewolf race, but also an important source of economy for their race, and most of the timber made by the White Tiger City, such as the crossbow and catapult, the eight-ox crossbow, and the feather arrow, almost sixty percent of the wood comes from this forest.

Of course, this is not to cut down giant trees, but to repair the branches of giant trees, because these giant trees are so unique that even the branches are stronger than ordinary trees.

In addition, the continuous construction of the branches of the giant trees can also make the giant trees in the Enchanted Forest grow better, and this is almost free, which can be said to be counted in one fell swoop.

It is precisely because of this that Zhou Yue's material reserves are so abundant, otherwise if they were to change to other ways, they would not be able to do it without millions of gold.

In addition to these 10,000 catapults, the Eight Bull Crossbow is also a weapon to defend the city, because the materials are less than the Catapult, the size is smaller, so the number of Eight Bull Crossbows currently accumulated in the White Tiger City has reached a terrifying 30,000 units, plus 10,000 reserve materials.

These 1,500 sky-cutting war crossbows, 10,000 catapults, and 30,000 eight-bull crossbows constitute the defense system of the entire White Tiger City.

Of course, this shows more and more Cai Yan's foresight and amazing talent when he designed the White Tiger City.

Although this city of white tigers covers a large area and can accommodate a million people to live normally, because it is built on the mountain, the effective scope of strategic defense is very huge, and there are no dead ends at all, from this point of view, it is almost like a miracle.

The entire city defense system can be roughly divided into three parts.

The first part is the outer city wall, under the premise of a height of 60 meters and a width of 15 meters, every 200 meters of the entire outer city wall, there will be a huge square tower with a total height of 80 meters, which can accommodate 50 soldiers and 20 eight-bull crossbows, which are specially used to snipe the enemy's generals, including sniping the desert wolf eagle, a flying beast, the effect must be very obvious.

In addition, every two thousand meters, the outer city wall will be built according to the terrain and mountain, a fortress protruding from about 50 meters to 100 meters outward, which is specially designed in the original city construction order, the overall defense and the entire city wall are integrated, and the top is firmly sealed with boulders, leaving only dense shooting holes to ensure the safety of the fortress.

Such a fortress is specially prepared for the best archers, such as mountain running battalions, elite archers, etc., which can accommodate up to 500 archers.

Although there are not many of them, due to the extremely high defense and security of this fortress, it will not be broken at all until the entire city wall is blasted open, and these elite archers can kill the enemy close to the city wall.

You know, in the world of the black city, due to the expansion of the power system, every soldier has the same superhuman skills, two or three thousand meters of charging distance, it doesn't take much time at all, and there is no need for any ladders, siege vehicles, once you start to charge, it is dense, like dumplings, rushing to the city wall, a few times by jumping, you can jump on the sixty-meter-high city wall, at this time, just relying on the parallel defense on the city wall, very passive.

And at this time, the protruding fortress of two thousand meters can play an unimaginable role!

As for the main city wall, there is no place for trebuchets, only 10,000 eight-ox crossbows, and in addition to the heavy infantry who are ready for battle.

The reason why this is so, according to Cai Yan's explanation, is because the fire rate of the catapult is too slow, and it is not cost-effective to attack enemy soldiers, maybe ten stones will not be able to hit an enemy.

Therefore, the catapult is mainly used to accurately hit the enemy's siege equipment, therefore, it is focused on the second line of defense, after all, the first line of defense is the main battlefield of melee hand-to-hand combat because the enemy charges too fast, and if you are not careful, it is easy to be destroyed by the outbreak skills of the enemy general.

The second part of the city defense system, that is, the second line of defense, is the city wall of the city of the White Tiger, this circle of city walls is about 1,500 meters away from the first city wall, and the shortest part is 800 meters, but it has been completely built on the ridge, so the overall height is more dominant, and on the basis of the first city wall of 60 meters, the height of 50 meters has been increased.

In other words, if you look at the plain outside the White Tiger City, the second wall is already 110 meters high.

Such a height is quite oppressive, so although the distance in a straight line is stretched to 1,500 meters, this terrifying height can still exert the great threat of catapults.

According to the actual test, on the second city wall, the kind of catapult that has been improved three times, the effective range of the projection can completely cover any point within five thousand meters, and with the height gravity bonus of 110 meters, as long as it hits, it will be 100% double damage crit!

Even if it is a Tiger tank, if it hits it, it will be smashed directly.

What's even more wonderful is that due to the advantage of occupying height, even if the enemy has a catapult capable of projecting a distance of five kilometers, it will definitely not be able to hit, at least it will have to be replaced by a catapult with a range of about seven kilometers.

But according to Wang Dazhong, it is impossible at all, unless it is the Qin army crossbow array of King Yingzheng of Qin, with the mythical domineering aura of Fengxiao Jiutian, or some powerful generals, such as the desert arrow god Zhebe, can be shot with one arrow, but that is a minority after all, the desert arrow god Zhe is no longer awesome, he is covered with iron and can twist a few nails, don't forget that all the catapults installed on the second city wall are catapults, 10,000 catapults, tired to death!

Therefore, Zhou Yue can almost imagine that under the intensive bombardment of these 10,000 catapults, even if the Mongols get more catapults and crossbows, they will have to eat ashes, which is absolutely suppressed.

And once the Mongols do not have a large number of long-range attack equipment to assist in the siege, then, the first wall of the White Tiger City can be safe and sound, if it is only by the crowd tactics to cut the city wall, Zhou Yue is too late to welcome, what are you kidding, the defense value of this city wall is as high as 50,000 points, and the durability is 15 million points, so if all the 150,000 troops of the Mongols come to cut the city wall, they will definitely faint to death.

In this way, the Mongols were left with the only option of attacking the city, but the large number of eight-ox crossbows and a large number of archers on the first wall were not vegetarians, which naturally caused huge casualties to the Mongols.

If the Mongols wanted to avoid this, they would probably have to send their flying troops, elite archers with desert wolf eagles as mounts, and take advantage of the high altitude dive to break the second line of defense.

I have to say that the Air Force will always be rich and handsome, whether in modern society or in this black city world, if the Mongols really dispatched tens of thousands of desert wolf eagles in one go to destroy the second line of defense of the White Tiger City, it would be very easy.

However, this is still in Cai Yan's design, and the third line of defense of the White Tiger City is waiting here.

This third line of defense is located in the center of the White Tiger City, and it is also the highest point, which originally belonged to the top of Phoenix Mountain, which is the city lord's mansion and the city within the city, with an area of nearly 800 acres, and is also isolated by a huge city wall, this circle of city walls is not high, only thirty-five meters, however, due to the relationship between the mountains, from the flat ground, it is at least three hundred and fifty meters high.

At such a height, you can just overlook the entire White Tiger City, and the field of vision is wide, which is perfect for sniping the Mongol air forces.

The walls of this city within a city are very ordinary, only ten meters wide, but because of the location, it is more dangerous than the sky, and 1,500 sky-cutting war crossbows are densely placed on it, which can basically ensure the killing of a large number of desert wolf eagles, even if there are still remnants, it will not become any climate.
