The Invincible Overlord of Heroes

The whole day, the Hell army was consuming the ammunition reserves of Graycastle.

The purpose was to prevent Graycastle's catapults from having enough reserves to saturate their output when Hell launched a real attack.

At the same time, it was also to determine the specific location of the Graycastle catapults based on the impact point and flight arc.

Catapults, especially those transported to the city wall, are generally fixed and difficult to move.

After determining the specific location of the catapults, Hell can choose to send troops to attack these catapults and destroy them directly.

At worst, determining the location of these catapults can determine their optimal attack range and projection angle.

For any catapult, no matter how long the attack distance is, there is a certain angle that cannot be projected, which is determined by the structure of the machine.

Of course, the designers of the city defense have thought of this problem long ago.

Therefore, on the general city wall, there are at least 4 or more catapults to ensure that there are no blind spots, at least except for this section at the foot of the city.

The catapults on the city wall are better. At least no matter how sudden the sneak attack of the crypt demon is, it can't fly to the city wall.

However, the catapults arranged behind the city wall are likely to be attacked by the crypt demon.

Night is coming. Even if all the magic lights in the city are lit, there are still many dark corners that cannot be illuminated.

Xu Lai arranged enough soldiers to patrol the city, and there are also scouts who listen to the ground.

But Xu Lai has never dealt with demons like crypt demons when defending the city.

And after all, it is a magical world. It is not known whether there is any sound when passing through the ground. Even if there is, it may not be impossible to cover it with magic.

The demons have not moved during the day, just to wait for the best time to act at night.

Xu Lai is almost 100% sure that the group of crypt demons will definitely act tonight.

Xu Lai has chosen the action targets for them. He built more than ten catapult positions in the inner city during the day.

This kind of catapult position built inside the city wall has no range bonus from the city wall, and has no advantage over the demon's catapult.

In fact, because the target cannot be seen, it can only attack according to instructions, and the hit rate is much worse than that of ordinary catapults.

However, if the demon troops are dense, it doesn't matter if the hit rate is a little worse, anyway, the demon can be hit no matter how it is hit.

The demons made so many mirror images and fake demons, isn't it just to consume their own ammunition?

Xu Lai didn't believe that he had so many catapult positions, and he only arranged a small number of soldiers for defense, and those demons would not be interested.

Completely different from the demon's guess, Xu Lai would not cherish any ammunition or catapult.

Except for those high-end goods sent to the city wall, ordinary catapults can be built hundreds of times a day with the ability of Qingfeng City.

It's nothing more than the craftsmen of Qingfeng City working harder and the workers moving more times.

Therefore, Xu Lai also specifically instructed the soldiers on defense to pay attention to the underground movements at any time, and to protect themselves first if anything goes wrong, and ignore the catapults.

These catapults are the traps Xu Lai prepared for the demons.

A large number of woven nets and freezing traps were laid in the catapult positions.

Due to the characteristics of themselves and the demon race, the crypt demons have strong resistance to fire and earth element magic.

The most common traps such as flames and ground spikes are not very effective for the crypt demons, and may paralyze these demons.

Woven nets and freezing traps are not intended to kill these crypt demons, but to trap them and not give them time to bury themselves again.

As long as these crypt demons are caught in the net or frozen, the troops arranged by Xu Lai will come immediately.

The crypt demons are good at sneak attacks, and attacking from behind can cause double damage.

But their frontal ability is only slightly stronger than that of the winged demons.

In order to be able to sneak underground smoothly, they cannot wear any equipment.

Except for a few leader-level crypt lords who have specially crafted exclusive equipment, the rest of the crypt demons are naked attributes.

The only thing they are stronger than the winged demons is that they don't have to limit their weight, so they can carry heavy shells and grow sharp back thorns.

Even though Xu Lai made sufficient preparations, he still miscalculated. The crypt demons did not appear all night.

Not only the crypt demons, but also the demons outside the city are also very powerful, but in fact they are just two or three kittens.

A flare was projected into the air, and countless dark demons could be seen rushing from the battlefield seven or eight kilometers away.

However, mirror images are not easy to distinguish, even in the daytime when the vision is good, light and shadow are needed.

At night when the vision is poor, even with flares, it is difficult to distinguish whether it is a mirror image or a real demon.

But anyway, Xu Lai doesn't need to cherish ammunition. Nearly a hundred catapults, trebuchets, and catapults on and under the city walls started together.

There are turrets on Gray Castle, but Xu Lai can't add them for a while, because the most important magic cannons of the turrets need high-level alchemists to make them.

Xu Lai has ordered several cannons from Qingfeng City, but even if the cannons are available, it will take two or three days for the craftsmen to build new turrets.

The turrets that are currently in use are still the ones that have been repaired before.

These turrets can fire shells cast by a large number of iron balls, which are not only powerful but also can scatter.

The disadvantage is that the previous magic cannons are all very ordinary stuff.

Not to mention compared with the cannons used by the tower mages, they can't even compare with the ordinary naval cannons on Xu Lai's fleet.

The power is okay, but the range is only one kilometer. Even with the dual blessing of ballistics and archery, the range is less than 1.5 kilometers.

In the night, Xu couldn't see clearly whether the demons were turned into fragments or bombed into slag.

Anyway, each round of catapult firing can destroy at least thousands of demons.

The movement speed of the demons is not slow. I guess Kerrigan has other speed-increasing treasures besides logistics.

At a distance of seven or eight kilometers, the demon infantry appeared in the range of the phantom archers after a few rounds of bombing.

With the bonus of the reinforced arrow tower, the phantom archers, who already have a wide range, took the lead in launching a powerful long-range offensive.

Thousands of arrows, with tens of thousands of phantoms, almost connected in a straight line, appeared in the sky continuously.

Whether it was the Hellfire summoned by Kerrigan using the Hell Gate, the Longhorn Warlord, or the mirror image copied by the Mirror Method.

When they walked into the attack range of the Phantom Archer, it was like encountering a wall formed by arrows, and no one could get through.

One after another, the Hellfire was blasted into pieces by the powerful arrows.

According to the previous experience of the demons, the projectile distance of human archers is indeed very long, but the power is extremely ordinary.

The hero of the Longbow Corps defending Lionheart City not only has the ultimate archery, but also has the archer specialty, and is equipped with a complete set of archer suits.

Adding these three items together, even the archers led by Xu Lai, no matter the range or output, are far from comparable to the opponent.

But the damage caused by the archers of Lionheart City is less than half of that of the Phantom Archer, even when the number far exceeds that of the Phantom Archer.

No matter how strong the defender of Lionheart City is, after all, the projectile only has a quarter of the damage.

No matter how high, strong, or how much bonus the arrow towers of the capital's walls are, they are reduced by three quarters at once. How much power is left?

The phantom archer not only has full damage, but also has the same bonus as the arrow towers. It can also bring more phantom arrows according to its own level.

The average level of Xu Lai's phantom archers is almost level 8, which means that each phantom archer can shoot 8 extra arrows.

The phantom arrows are not full, but the demons have only eliminated one-tenth of the troops, and the remaining nine-tenths are either mirror images or cannon fodder.

Mirror images cannot withstand any damage. Cannon fodder, whether they are driven and enslaved humans, or little demons, are extremely fragile units.

This kind of unit may be able to string seven or eight of them with one phantom arrow.

It is impossible to maintain such a firepower configuration for a long time.

A phantom archer, even a phantom arrow saint of level 8, only has 3 quivers and 120 arrows.

Under the special effects of archery and logistics, the amount of ammunition can be increased by 30%, which is only 156 rounds in total.

With the terrifying firing rate of the phantom archer, 156 rounds of ammunition can be fired in less than three minutes at the limit.

Of course, considering the quality of the demons, there is no need to maintain such an exaggerated strength.

However, a phantom archer will use up their daily free ammunition in ten minutes at most.

For the rest of the time, either Xu Lai will provide ammunition supplies or arrange for them to rest.

A reinforced arrow tower with three layers of shooting positions can accommodate up to 12-18 archers for shooting at the same time.

Xu Lai arranged three times the number of phantom archers in each arrow tower, allowing them to rotate at any time to ensure that the arrow tower output is continuous.

Ten minutes later, seeing that the demons could not come up, Xu Lai ordered to reduce the intensity and release some demons appropriately.

Anyway, there are still tens of thousands of sky archers on the city wall. If it is not enough, more archer masters can be mobilized to come up.

After reducing the attack frequency, there were indeed occasional tough Hellfires that broke through the phantom defense line.

However, at this time, there were still 4 turrets and hundreds of crossbow carts on the city wall waiting for them.

Under the blockade of the turrets and crossbow carts, these fish that slipped through the net could not rush within one kilometer.

Helplessly, Xu Lai could only order to reduce the frequency again, let the phantom shooters shoot and rest for two or three seconds.

But even so, because the demon army was filled with too many illusions, after breaking through the crossbow arrows and artillery fire, there were still few left.

These demons did not need to work the sky shooters, they only needed to call on the batch of recruits recruited after the founding of the country.

These recruits followed Xu Lai all the way from the grassland to Gray Castle, and were led by Lena to fight several tough battles, and they also ate dragon meat.

Their level at this time was not low, and the average level had exceeded level 5, basically mainly level 5, supplemented by a small amount of level 6 and level 7.

They would conduct targeted attacks on the demons that broke through the defense line at close range to gain experience.

Xu Lai took a quick look at the demons outside the city and lost interest, so he focused on the city.

However, the movement inside the city was even quieter, and there was no unusual movement except for the normal patrols.

The actions of the demons at night were really a lot of noise but little action, and Xu Lai did not feel any pressure at all.

On the contrary, the demons themselves lost some troops.

However, Kerrigan was not impatient at all. The loss of these demons was nothing to him, not to mention that most of them were summoned, and it would be in vain if they died.

As long as he made his move without showing any signs of defeat, and let his demons know that he was taking action, it would be fine.

In addition to consuming the ammunition of the defenders in the city, the actions during the day and at night also allowed Kerrigan to have a basic assessment of human strength.

Just like the terrifying continuous rain of arrows.

Although he had heard reports before and knew that Xu Lai had a very powerful long-range force.

But he didn't know how strong this force was.

Now he knew that with the bonus of the arrow tower, those archers could shoot nearly two kilometers away, and the key power and speed were extremely terrifying.

If he didn't know the abilities of these archers and rashly concentrated his troops to attack, he would definitely suffer heavy losses.

Although the continuous rain of arrows did not last long, Kerrigan knew that as long as the opponent had it, he would definitely be able to last.

Xu Lai must have an extremely large space ring on his body, even at the artifact level.

Therefore, Kerrigan dared to conclude that as long as Xu Lai was willing, this continuous rain of arrows would definitely last for a long time.

In addition to the human archers, Kerrigan was also concerned about Xu Lai's efforts in city defense.

After taking Lionheart City with great effort, Kerrigan seized a large amount of wealth and a large population.

But these wealth and population could not be used by him for the time being.

The key is that he had no time to stop and sort out his internal affairs, and most of the siege weapons he had accumulated for several months were lost in the battle of Lionheart City.

Moreover, he came back in a hurry, and it was impossible for him to bring those bulky guys.

Briston had fought with Xu Lai before, and the city was broken, leaving only the inner city.

Kerrigan dismantled all the catapults from the inner city wall of Briston and modified them into new catapults.

However, these more than 20 precious catapults are now Kerrigan's treasures, and he is not willing to take them out to consume with Graycastle easily.

Only when the catapults and siege vehicles of Lionheart City are delivered, he may take them out to consume with Xu Lai.

Some time ago, Kerrigan saw Xu Lai's cavalry, and today he saw Xu Lai's city defense weapons and some archers.

Kerrigan touched his chin and called off the troops before dawn.

His camp had been moved to the front line, only 30 kilometers away from Graycastle.

The crypt demons were a surprise force arranged by Kerrigan, and they must cooperate with the main force.

As for whether this surprise force could form such an effect, Kerrigan was not quite sure.

The best result he hoped to achieve was to break the two layers of Graycastle's walls directly from the inside to the outside.

Under the sudden sneak attack, no matter how strong the long-range troops of humans were, it would be useless and they could only rely on melee guards.

If the crypt demons could open the two city gates directly, it would provide great convenience for Kerrigan's siege.

But if the crypt demons did not have this strength, Kerrigan would need to arrange them to sneak attack the catapult positions, the granaries and arsenals, etc., to create chaos in the city.

What to do and how to do it depends on the strength of the human infantry.

So Kerrigan did not stop his troops. After adjusting the formation, he continued to attack Graycastle the next day. (End of this chapter)
