The Invincible Overlord of Heroes

There are twelve cities of different sizes near the Gray Valley.

The smallest one, covering only three or four acres of land, is located at the entrance of the Gray Valley. It is a militarized fortress with almost no living facilities.

Of course, with such a small area, a castle of only 2,000 square meters cannot accommodate too many troops.

However, this small fortress is built quite solidly. Not only are there steep slopes on both sides, but the city walls and arrow towers are also reinforced models.

In addition, the city walls of this fortress called Little Gray Castle are completely enclosed.

After the city walls are built with the Heart of the Castle, stonemasons are found to build the spires on the city walls.

Because there is the Heart of the Castle, building according to the architecture provided by the Heart of the Castle can not only greatly save materials, but more importantly, it requires very little time.

Before Xu Lai came, the city wall of Qingfeng City could be repaired in one day. After it was demolished and rebuilt, it took more than half a year even with the help of the Heart of the Castle.

This is after recruiting a large number of farmers, and even upgrading them to builders and construction workers.

Ordinary fortresses would never spend so much time, effort and money.

But Little Gray Castle is different. Little Gray Castle blocks the only passage in and out of Gray Valley.

The terrain of Gray Valley is narrow, and the widest position can only accommodate 5 or 6 riders side by side.

Little Gray Castle is located at the entrance, and there are high slopes on both sides. Now it has been transformed into lava terrain.

Gray Valley is a place that Kerrigan personally watches. Even if it has not been completely transformed yet, it has been completed for the most part.

No one knows how many demons are ambushed on the slopes on both sides of the lava volcano and magma traps.

Xu Lai can be sure that there must be demon ambushes on both sides.

Even if Jian Yuan has reconnaissance skills, it is hard to say whether he can find the ambush. Even if he finds it, there will definitely be more than one ambush.

Xu Lai has to wait for Lena to gather anyway, so he is not in a hurry to occupy Little Gray Castle, let alone send troops from both sides of the valley.

Little Gray Castle is not big, and it is impossible to set up a large formation in front. It is obviously not possible to rush over in a swarm.

Xu Lai didn't have many siege equipment such as crossbows and catapults, but they were of good quality. They were captured from Kasai City before.

It was also because the lightning storm was only interested in moving and living things, and had no reaction to mechanical things such as houses and equipment.

Besides, the demons were not stupid enough to think that they could rely on these equipment to block the damage of lightning. At least they had to find a place with a roof.

Unfortunately, Kasai City was still too severely damaged. Many equipment were accidentally damaged. Some equipment needed to be repaired before they could be transported.

But these were enough for use.

The structure and size of Little Gray Castle meant that not many city defense equipment could be deployed.

The demons inside could only watch Xu Lai use the catapult to smash the arrow tower and the city wall of Little Gray Castle bit by bit.

But Little Gray Castle was built extremely solidly, especially the strong top on the city wall. On average, it took three hits on the same part to break through.

The arrow tower had a higher durability. If you want to knock down an arrow tower, you need to hit it at least ten times.

Obviously, the standard arrow towers in the fortress city do not have such high durability and defense.

This level can be compared with the castle city.

Of course, that refers to the general castle city.

Not to mention the capital-level city like Qingfeng City, even the reinforced arrow tower of the Stone City is stronger than this.

While attacking the city, the crossbowmen who control the catapults and the catapults themselves will also be attacked by the lava trolls in the arrow towers.

Fortunately, these arrow towers have not been transformed into fire magic towers. They only increase the range of the lava trolls, and the power increase is not as terrible as the fire magic tower.

Even so, under the continuous treatment of the priest, crossbowmen continue to fall to the ground and die.

In fact, the death of some crossbowmen is nothing, after all, there are a large number of priests who are dedicated to treatment, and a group of crossbowmen can last for a long time.

And after they die, they can be resurrected by the Angel Legion immediately. For Xu Lai, there is no loss at all.

It’s just that the catapults are constantly destroyed by the flames, and Xu Lai is distressed.

As a mechanical unit, this thing can't be revived.

But fortunately, the materials can be reused. As long as there are enough craftsmen, it can be restored to 70% or 80% at least.

Even if we are fighting outside now, there is no stable and reliable city in the rear.

Let alone recruiting craftsmen, even if there are craftsmen, there is no suitable place to produce and repair them.

In other words, the existing catapults are used one by one, and there is no replenishment in a short time.

Therefore, after smashing all the arrow towers, Xu Lai ordered the catapults to be packed up and make way for the infantry.

Many gaps were smashed on the wall.

The long ladder with a hook on the top is enough to support the infantry to enter.

Although the top of the wall of Xiaohuibao is a repaired spire, there is still a small square frame every few meters, which is the reserved shooting hole.

Whether it is an archer or a crossbowman, humans are not big in size, and one shooting hole is enough for several people.

There are not many large-sized crossbow carts, catapults, and small gray castles, so there is no need to open holes.

Small Gray Castle is not a fortress built completely according to the heart of the castle, and there are traces of reconstruction and processing everywhere.

Therefore, the demons cannot completely transform this kind of fortress by polluting the heart of the castle.

This is also the reason why the arrow tower was not changed into the fire magic tower.

The demons naturally had no way to forcefully change the processed city walls, unless they had to tear them down and rebuild them.

But obviously, the demons were not willing to do so.

The demon archers, such as Magog, were relatively small in size, and one shooting hole could accommodate two or three.

But for fire trolls and lava trolls, they had to hunch over to walk in this capped city wall, and the shooting holes were not enough for them to use.

But even so, Xu Lai was reluctant to waste the catapults, and would rather let the infantry of the first landing camp launch a charge.

In addition to the infantry, Xu Lai also sent out the priest group to cover.

The priests had higher defense than the priests, and there was only one demon general guarding the small gray castle, and the attribute bonus given to the soldiers was not high.

Of course, the demons were not without heroes. Even if we didn't count Mendis who escaped back, there was still a demon hero in the Gray Valley.

But this small gray castle was too small to accommodate too many defensive soldiers.

Whether it was Mendis or another demon hero who did not show up, they all knew that this small gray castle would definitely not be able to be defended.

Moreover, Xu Lai still had the advantage of air force, even if he would not easily advance from both sides of the valley.

But if the defender escaped, Xu Lai would definitely not let him go, and it would not be a big deal to send a few masters to fly over and kill him.

Considering this situation, the two demons certainly did not want to stay and wait for death.

The bonus was not much, and the priests and high priests were both level 5 and level 6 professionals, and they were also buffed, and they were protected by Xu Lai's fire control magic.

The key was that behind the priests, there were priests responsible for blood.

Even the front-line soldiers of the first landing camp had priests and high priests to treat.

This circular ladder layout just took all of them into consideration, and also allowed the priests and high priests, who Xu Lai needed most now, to gain the most experience.

The priests used magic attacks. Although the attack range of this attack was not as good as that of the shooter, the hit rate was much higher than that of the shooter.

Although the shooting hole is not big, the priests stand far away, which can accommodate several light balls at the same time.

Behind the shooting hole is the fire troll. The huge bodies of the lava trolls have no place to hide even if they want to.

The small city wall is filled with sturdy demons, so that the charging vanguard soldiers have a hard time squeezing into the city wall for street fighting.

It is also thanks to these vanguard soldiers. If Xu Lai sent the infantry of the Qingfeng Legion.

The spearmen are okay, at least they can poke the spears at the top of the ladder.

If it were the sword and shield soldiers, I am afraid that they would not be able to cut a gap for a year.

Even with the addition of god-level offensive skills, the basic attack is not high, and it is still difficult to break the defense of high-level demons.

And the only demon building in this small gray castle is the demon birth pool.

The birth pool has two functions for demons.

One is to hatch little demons. Whether it is used as food for high-level demons or slaves, little demons are very useful.

Another function is to heal wounded demons.

Now there are only a few gaps for attack. If it weren't for these well-equipped and basically all-powerful skills, it would be difficult to break the situation for a while.

However, the warriors of the first landing camp can grab a place on the wall by relying on warrior skills such as charge, shield strike, powerful strike, and sweeping thousands of troops.

Due to the narrow terrain and crowded demons above, the warriors of the first landing camp cannot be effectively rotated.

More importantly, although the priests know simple healing spells, they can only be used when the soldiers of the first landing camp appear in their field of vision.

That is, either climbing the ladder outside or killing to the shooting port, no other effective treatment can be obtained.

Of course, except for Xu Lai using healing spells.

Xu Lai's spirit value is not low, and one healing can restore a lot of health.

And because of the size of the small gray castle, the scale of the war is not large, Xu Lai has many opportunities to cast spells, and basically a round of spells can be released in about five minutes.

Unfortunately, it is easy to recover health, but it is impossible to recover physical strength.

Especially the warriors of the Xiandeng Camp, who have various skills. They are fierce, but they cannot last long.

The mana of the warrior profession is not high, so most of the skills actually consume physical strength.

Like charging, charging, and slamming, they all consume physical strength in multiples.

After fighting for an afternoon, the warriors of the Xiandeng Camp on the front line were exhausted, and Xu Lai had to order a retreat.

Fortunately, they had the upper hand, and even if they retreated, they could calmly take away their own bodies.

This is a mandatory requirement, after all, you can live with corpses.

If you don't take away the bodies of your companions, then in a blink of an eye, your former companions will become food for demons.

If it is a real siege, although the Xiandeng Camp failed to take down the city wall.

But as long as Xu Lai fills in the soldiers of the Qingfeng Legion in time, he can still occupy a section of the city wall steadily.

However, Xu Lai is not anxious, and after nightfall, the human vision is blocked, and the demons will inevitably launch a counterattack.

Xu Lai was waiting for Reina to come over, so he was not in such a hurry.

The next day, after eating and drinking, he repeated the same trick.

However, the section of the city wall that was seized yesterday had been reoccupied by the demons.

They even repaired the city wall and patched up the holes on it.

The demons could not do it, there must be human craftsmen in the city.

However, as long as the city wall is still being destroyed, these craftsmen should be fine for the time being.

After all, there is enough food stored in the small gray castle, and the demons do not need to rush to eat people.

In the morning, the first batch of soldiers seized a section of the city wall, and in the afternoon, they were replaced by the spear and shield soldiers of the Qingfeng Legion.

Although the attack power of the heavy shield infantry is not good enough, with the heavy shield, the defense is extremely strong.

Although the demons are of a higher level, they have no offensive skills, and the big shield has strong defense. They also have the ultimate defense skills and the angel alliance to protect their bodies.

In this case, as long as the heavy shield soldiers can protect their bodies and prevent their bodies from being exposed outside the shield, it is impossible for the demons to break through the defense.

The heavy shield infantry can even put away their single swords and concentrate on defending with two hands holding the shield.

The spearmen behind them can use the advantages of the spear to attack the demons in front of the heavy shield soldiers.

There are 5 points of strength and constitution bonus provided by the statue of the god of war, as well as the resistance of the spearmen behind them.

Even though the demons were generally stronger than humans, they could not take down the human spear and shield formation for a while.

With Xu Lai in charge, and without him participating in the battle, the tactics also provided a lot of additional attributes.

This bought a lot of time for the human infantry corps, and they were able to continuously expand their territory on the city wall.

When night was about to fall, the spear and shield soldiers actually occupied half of the territory on the city wall without any long-range support.

On the third day, the catapults had completely lost their threat.

The enemy's limited long-range troops had been completely destroyed by the priests, and a lot of their manpower had also been buried.

Although they still failed to take down all the city walls today, they killed thousands of high-level demons.

In the end, the demons could not even send out the warlords, whose ranks were no longer very advantageous.

They could only rely on the long-horned demons summoned by the evil gods to fight.

The long-horned demons had no advantage over humans in terms of rank.

If it hadn't been late when Xu Lai came, he should have been able to take down all the city walls that day.

By the fourth day, the demons on the city wall had become sparse, and there was no need to send the advance battalion to seize the breakthrough.

Xu Lai did so. Compared with the advance battalion, the recruits of the Qingfeng Corps needed to upgrade their levels more.

The demons received a death order, so no one dared to escape even though they knew they had no chance of winning.

With others not competing for experience, Xu Lai spent four days and finally took down the small gray castle.

And successfully liberated more than 300 human craftsmen imprisoned in the small gray castle.

At the same time, the average level of the Qingfeng Corps infantry was finally raised to level 5, and more high priests and a small number of angels appeared.

After occupying the small gray castle, Xu Lai planned to use it as a base to clear the uphill on both sides. (End of this chapter)
