The Invincible Overlord of Heroes.

Xu Lai blinked. This siege was divided into three parts, and the three parts were not close to each other.

On both sides of the valley where Xu Lai was located were mountain walls several dozen meters high, and he could not see the situation of the troops on both sides at all.

Therefore, in addition to protecting the Naga and the Vanguard Camp, Xu Lai integrated Eric and Emilia's troops into his own legion.

Reina and the Qingfeng Legion she leads will lead the army independently and will not unite with Xu Lai.

The disadvantage is that the attributes of the two sides' troops cannot complement each other. For example, Xu Lai cannot take advantage of Rena's ultimate ballistics, defensive skills, etc.

Similarly, Xu Lai's ultimate offensive skills and super speed talent do not cover the Qingfeng Legion.

But there is also an advantage. The advantage is that the strategic casting opportunities of both parties will not overlap, and they can each release their own spells.

On the other hand, even if other troops suffered relatively heavy losses, the morale loss of our own troops was only based on the standards of friendly forces.

The morale loss caused by friendly forces in battle cannot certainly be compared with that of one's own troops.

Generally speaking, depending on the ratio of friendly forces to your own forces, the morale loss will be only about 3-7 levels of your own forces.

The more friendly forces there are, the greater the impact they will have on your side.

However, this influence was not important to Xu Lai and his men, because they were in a low position and could not see clearly the movements of the friendly forces above.

The last advantage is the convenience of command, which can be adapted to local conditions.

Another commander ordered the entire army to charge, and the catapults in the valley also went to hit the enemy's city walls.

However, the lack of ballistics has a great impact on Xu Lai.

Although the enemy only had one crossbow launching the attack, since the enemy was already within the attack range of the crossbow, the catapult would certainly be able to attack as well.

At this time, although our own catapults can also attack, they are several kilometers away after all, so the hit rate will be greatly reduced.

Xu Lai gritted his teeth. This time he was not going to take it slow. There was no point in delaying any further.

"Let the battering rams go first and charge at the city gate!"

Generally speaking, battering rams are used to attack city gates, and the city gate drawbridge needs to be destroyed first.

But Graycastle was built directly at the exit of Grayvale, and the biggest problem here was that it was inconvenient to divert water.

Therefore, Graycastle has no moat, and naturally there is no need for a drawbridge, only a city gate.

Two battering rams built with steel plates drove side by side towards the city gate.

Behind them, there were many wrecked cars that were just covered with iron sheets.

Time was short and Xu Lai had no time to prepare. He only relied on the warehouse ring to find dozens of battering rams.

Fortunately, Qingfeng City is no longer what it used to be. There are now many craftsmen, mages, and alchemists.

Although Xu Lai's request was urgent, he still got two good things for him.

The all-steel frame is mixed with stainless steel baffles and steel-clad strikers weighing several tons, and is enchanted with an acceleration effect.

Without this acceleration effect, such a ramming machine would not be able to run at all even if it had four wheels made of steel.

If Xu Lai were here, he might study the track structure.

But this is actually just self-consolation. Xu Lai had wanted to set up a research institute a long time ago, but it was only after the founding of the People's Republic of China that he was able to gather enough talent and resources.

Even if it was done, Xu Lai himself would not be able to participate in the research. As a king, he really doesn't have time to meddle in it, to be honest.

Besides, he was not good at research. What he knew about modern technology and modern ideas was almost the same as what any other advent hero knew.

Even if there are people who are professionally engaged in scientific research in various fields, the results will definitely be ten thousand times better than Xu Lai doing it himself.

Of course, these are all things that happened later. The most important thing for Xu Lai to do now is to break open the gate of Graycastle opposite.

As a large military fortress, the gate of Graycastle is not simple.

In addition to using the top layer of materials, many additional layers of spells were solidified.

The most important thing is that the gate of Graycastle is a double gate. Even if the outer gate is broken open, there is still a long corridor inside.

The corridor was originally staffed by human archers, but now crowded with them are a large number of fire demons.

There's no way. The place is so small. If the demons deploy fire trolls with stronger attack power, I'm afraid even a few of them wouldn't be able to squeeze in even with their hunched bodies.

But even so, it was still impossible for the defenders to allow human battering rams to ram the city gates so recklessly.

The sound of the wind was heard, and a large number of huge rocks smashed towards the human position madly.

Graycastle did not deploy many trebuchets, but all of them were adjusted in position, and most of them were aimed at the open space in the valley.

In such narrow terrain, Xu Lai and his men had no place to hide. The most they could do was to ask the infantry pushing the catapults and battering rams to raise their shields.

However, even if it is just a low-level catapult, its destructive power is extremely terrifying.

What's more, most of the troops deployed in Graycastle are high-level catapults, and the damage is even more exaggerated.

With the help of ballistics, it’s no wonder that the people pushing the cart are just ordinary infantry.

Even if the most elite royal guards of the Qingfeng Legion were here, they would be smashed to pieces.

Perhaps only Reina, who is good at defense, and her top-level infantry can survive this wave of stone-throwing bombardment.

Xu Lai can do it too, he uses the Paladin's holy armor.

Between every few siege weapons, there would be a Holy Light Knight following, responsible for providing protection for the soldiers pushing the carts in front, behind, and on both sides.

Of course, although the holy armor can help soldiers resist damage, if the boulders hit the siege vehicle, it will still cause serious scars.

Although the craftsmen of Qingfeng City worked hard, except for the two at the front, the rest of the siege vehicles could only be hit two or three times at most.

If you accidentally trigger a lucky hit or a critical hit, it will be destroyed in two hits.

Being destroyed is not scary. What is scary is that the terrain is narrow and the destroyed siege weapons will block the road, hindering other vehicles.

It takes a lot of time for the soldiers to clear these obstacles.

Even if the holy armor could last for an extra ten seconds with Roland's expertise, it was still far from enough.

Xu Lai had no other good ideas and could only rely on luck.

This is why, even though he knew that being at the front of the line would definitely be a special target for the enemy, he still put the two assault vehicles at the front.

The Great Demon has the effect of reducing the enemy's luck, but it seems that even in Graycastle, there are no Great Demons deployed.

I don’t know if this is the reason, but Xu Lai is pretty lucky anyway.

The enemy's catapults fired indiscriminately, causing some obstacles to the troops' advance, but failed to cause any damage to the two battering rams in the front row.

Suddenly, there was a loud bang, and a thick wall of fire suddenly burned about a hundred meters away from Graycastle. The catapult has a minimum attack distance limit. At this position, only the ballista and the demon's long-range troops can attack.

However, although the one minute of invincibility had already passed, Xu Lai cast the magic of fire control on everyone before setting off.

With this effect, the charging troops simply ignored the triggered fire trap.

On the tower of Graycastle, an evil god of hell grinned grimly and calmly opened his spell book.

The next second, a dispelling spell emitting blue light was thrown out.

As the ancestors who played with fire, demons were very sensitive to the magic of controlling fire that could restrain fire spells.

As early as when the human army charged forward collectively, he keenly sensed the existence of the magic of fire control.

However, it was not until he saw the human troops rushing into the fire trap that he calmly released the Dispersal Technique to drive away the fire control magic.

Without the magic of fire control, he was worried that humans would not dare to rush into the fire. In that case, his fire trap would be useless and a lot of energy would be wasted.

But just as the evil god of hell grinned foolishly, a red shield continued to be put on everyone.

Xu Lai tore open an extremely valuable scroll of the ultimate fire-controlling magic without hesitation.

The evil god of hell hesitated for a moment, but in the end he was reluctant to tear open a spell scroll and allowed the human troops to rush through the wall of fire.

There are no other traps after the fire wall, mainly because most demons are only good at fire spells.

But even though there were no more traps behind the fire wall, the gate of Graycastle opened by itself.

Teams of long-horned generals wearing heavy armor filed out from behind the door.

The evil god of hell would never easily give humans the opportunity to approach the city gate, and it was even more impossible for him to let the siege vehicle, which looked powerful, crash into his gate.

Xu Lai didn't have any good solution. The people pushing the cart were just a group of ordinary infantrymen that Xu Lai had selected from the logistics corps.

Although the average level of this group of infantry has reached level 5, it seems that they are not much different from the level 6 Long-Horned Warlord.

If the Statue of the God of War and the Angel Alliance are included, there is no difference even in the basic attributes.

However, the infantrymen that Xu Lai had selected were logistics soldiers. Their main task was to push carts and transport goods, and they had rarely used the weapons in their hands.

Moreover, as logistics soldiers, their equipment is relatively inferior. They are wearing a blank suit, and except for the breastplate and shield, there is almost nothing good on them.

Their opponents, on the other hand, were a group of long-horned warlords armed to the teeth. Not only were they equipped with luxurious equipment, but they also held long whips that could enable medium-range attacks.

Xu Lai's infantrymen were beaten all over the head.

Fortunately, although these logistics soldiers are not good at fighting, as heavy shield infantry, they still have the defensive instinct.

The horned demons are the meat shields of the hell army. Even the highest-ranking horned warlord among the horned demons still has this fate.

The purpose of the evil god of hell sending out this long-horned general was not to kill the human infantry, but to let them stop the human progress.

The fire trolls and lava trolls on the arrow tower were throwing fireballs with all their might.

Fireballs can't do much damage to infantrymen who have been blessed with firebending magic, ultimate resistance, and anti-magic cloaks.

However, the battering ram they were pushing did not enjoy any magical effects, and its durability continued to decrease little by little.

If this continues, no matter how durable the two rams are, they won't be able to hold out for long.

But the road was narrow, and even sending cavalry to break through the roadblock was only possible in dreams, let alone transferring long-range troops to engage in counter-fire.

Fortunately, at this time, the vanguard camp led by Eric had already arrived on both sides of the Gray Valley.

Eric's vanguard camp was originally composed mainly of lightweight infantry, and did not need to carry heavy equipment such as catapults and battering rams like Xu Lai.

Therefore, although the mountain road was difficult to walk on, with the help of Xu Lai's super speed talent, they still arrived at the city quickly.

However, on their side, all they could see was the city wall.

And because there was no baggage, there was definitely no high-end equipment like siege towers, at most there were just some long ladders.

The walls of Graycastle were not capped. It was not a small fortress like Little Graycastle. Big Graycastle was dozens of meters high, and it was impossible for ordinary people to climb up.

Eric was not in a hurry to launch an attack on the city. Although he had to attack the camp first, he was not going to die.

The fire trolls on the city wall threw fireballs down for free.

Of course, the damage of the fireball is not high, but the opponent has a large number of crossbows.

Now we can use the shield to resist, and with the additional defense provided by the Angel Alliance, we can hold on for a while.

If we really want to climb now, without the protection of shields, I don’t know how many people will die before we can climb up.

Eric waved his hand, and the phantom shooters in the rear quickly rushed over under the cover of the infantry of the vanguard battalion.

The terrain here is not flat, but it is not like in the valley where you are squeezed by the mountain walls on both sides and cannot move.

Although the Phantom Shooters cannot use their most proficient scattered formation, at least it can ensure that every shooter has a shooting position.

Even if they cannot see the target for some reason, they just need to shoot arrows at the city walls and arrow towers.

These more than 2000 phantom archers are the ceiling of long-range troops, with extremely long range, extremely high damage, and exaggerated number of arrows and firing rate.

For a moment, the left side of the city wall, which was under the charge of the Qingfeng Legion, was covered by a rain of arrows from the Phantom Archers.

The fire trolls above were shot and exploded from time to time, splitting into multiple low-level fire demons.

Theoretically, if a fire troll splits into two fire trolls, the output will be significantly increased.

However, even with the advantage of the high walls, the fire trolls could only barely move some of the front-line troops.

This is because the phantom shooters have no place to stand and output damage, so they have to squeeze forward.

If it were a situation on the plain, with the Phantom Archer's range advantage, it would be impossible to compete with the Fire Demons in range unless the Fire Demons' walls were raised by another 20 meters.

The huge casualty ratio between the two sides was completely on a different level, which was something the Evil God of Hell could not accept at all.

He gritted his teeth and tore open the sheet of Dispelling Magic to get rid of the fire control magic on the human first, otherwise he would not be able to fight on.

Xu Lai quietly moved to the front row and suddenly fell into hesitation.

He had one more chance to cast a spell, but he hesitated between the fire-controlling magic and the earth-shaking magic.

Back then, Xu Lai’s confident Stone City was almost breached by the Beast King’s earth-shaking power.

In order to attack the city, Xu Lai tried every means to buy a high-level earth-shaking scroll, and he was even reluctant to tear it open and use it.

Thinking of his strategic goal, Xu Lai finally gritted his teeth and released this high-level earth-shaking power. (End of this chapter)
