The Invincible Overlord of Heroes.

In addition to Xu Lai himself, the troops under his command also advanced in large numbers. Naturally, the ones who advanced the most were the Naga Guards led by Emilia.

However, something really funny happened to Emilia.

Because Xu Lai took care of all the expenses, Emilia didn't have to prepare much.

This time, the large-scale advancement includes all levels except the Naga Swordmaster who has reached the maximum level.

To promote any of the Eight-Armed Nagas, you will need tens of thousands of gold coins, and you will also need to bring some rare resources.

As for gold coins, the spoils alone would definitely not be enough, but fortunately Emilia still had her own small reserves, pocket money and so on.

Even with this little pocket money, and the tens of thousands of gold coins from the spoils of war, it is not enough for many people to advance.
The advancement of the deep-sea tribe's strength is their own business, and no commander will pay for the upgrade costs out of his own pocket.

However, Xu Lai did this, and Emilia also felt that after her strength was improved, she would be able to better deal with future crises.

So Emilia went straight to Xu Lai and asked to borrow 20 gold coins.

Emilia searched the Naga Guards for various items and estimated that the maximum shortfall was only 20 gold.

However, Xu Lai directly gave her 50 yuan, so that the girl wouldn't be embarrassed to ask again if she wanted to advance next time.

The other person just asked to borrow money. In fact, even if he wanted it, Xu Lai should give it to him.

It is only natural to ask others to help and pay some military expenses.

Only when you benefit others, will they be willing to help you actively when you encounter such a situation in the future.

Otherwise, he would have to go to war every other day, and the good friendship between him and the Nagas would be exhausted.

After the battle, Xu Lai led the large army to rest for a day.

Elvi, Jian Yuan, Eric and others led a small force to clear out all the demon cities, strongholds, towns and resource points within a radius of thousands of kilometers.

The golden dragon and the black dragon won’t take that long, but there are still three sacred beasts and the water unicorn.

Xu Lai wants to make full use of these three sacred beasts before they disappear naturally.

With these three water unicorns leading the charge, there is also a large group of Seraphim waiting covetously in the rear, and dozens of archangels acting as thugs.

Even without Xu Lai's protection, he encountered almost no decent resistance.

After Mendis was defeated, he did not dare to go back directly to Kerrigan.

In the past two days, Kerrigan has been really angry and sent out a large number of slaves and low-level demons to consume the strength of mankind.

However, it is not known how long this consumption will last.

As a last resort, he had to dispatch a large number of troops to besiege Lionheart City and cut off its transmission function.

This requires a large number of troops, especially since Lionheart City is so huge that it cannot be supported by slaves and low-level demons.

Kerrigan can only send mid-level troops to the battlefield, but these mid-level troops cannot be completely consumables. No one can afford it.

Especially when the opponent is human, the priest's treatment and recovery can increase the endurance of human warriors several times.

It is generally recognized by the nine camps that the most difficult to deal with are humans and undead forces.

Kerrigan doesn't have the Gate of Hell, so he can't summon cannon fodder from Hell for the time being, so he can only send a letter to urge Mendis.

After Mendis was defeated, he did not dare to tell Kerrigan the truth, let alone allow Xu Lai to seize the city of Kasai.

Of course, truth cannot be hidden, and there is a female devil in Kasai City.

However, the Abyss Lord Kerrigan, who was always prone to anger, did not blame Mendis this time.

After learning that Xu Lai led the human troops to advance triumphantly and captured several large cities on the Kasai Plain.

Kerrigan was not in a hurry to ask Mendis to come back to join the battle, but just asked him to send someone to return his Hell's Gate.

Although Mendis was extremely reluctant to part with the Hell's Gate, he did not dare to disobey Kerrigan's orders and had to send the Hell's Gate away.

The latest order given by Kerrigan to Mendis is to stop the human forces from advancing eastward at all costs.

After crossing the Kasai Plain, there is only a gray valley between Kerrigan's temporary base, Briston.

Briston was originally the capital of the Western Empire. After being occupied by Kerrigan, it had long been transformed into a hell city.

Not only did Kerrigan move his palace into Briston, he also opened the second gate of hell in Briston.

Kerrigan's original body in hell was seriously injured after opening two gates of hell.

It is impossible to open a third one in a short period of time.

And this short period of time is only relative to the demons in hell. If converted into human time, it would not be possible within a hundred years.

In order to defend Briston, Kerrigan also specially transformed the Grey Valley, making the terrain here more rugged and full of magma.

The original Ash Valley was named because of the lack of green plants, but at this time, the Ash Valley had long since turned into a lava valley.

But no matter how good the terrain of Gray Valley is, without a superhero in charge, Kerrigan felt really uneasy.

This is also the reason why he was able to suppress his anger and let Mendis make amends for his crime.

However, Kerrigan authorized Mendis to command the army of Grey Valley.

But Mendis was not qualified to mobilize the troops of Grayvale, and the troops there had to be stationed in Grayvale without fail.

After suffering a round of defeats, especially after losing all of Ferris's Fire Elves, Mendis became much more low-key.

Not only did Mendis not interfere in all the defense of Kasai City, but he actively cooperated.

Utilizing the castle gate transformed from the city of Kasai, cast the Hell's Gate spell and actively help evacuate the surrounding demons.

In addition to evacuation, the Hell Gate can also summon demons from Hell.

However, none of them knew when Xu Lai would attack.

It is easy to summon the demons from hell, but you cannot just ignore them once you have summoned them.

Demons are not slaves, especially those that are summoned, who don't even need to be paid wages.

Normally summoners have to offer sacrifices in order to summon creatures from other dimensions for help.

Mendis used the Gate of Hell to forcefully summon them. If he doesn't treat them well with good food and drink, they might get furious and start a fight with their own people first.

However, demons consume a lot of energy, especially those that are carnivorous.

Even if they ate up all the slaves in Kasai City, they wouldn't be able to hold out for long.

Moreover, the demons do not produce anything. If they really eat all the slaves, who will help them reproduce?

What's more, the summoned demons are not permanent.

Generally speaking, the demons summoned through the Gates of Hell only exist for 24 hours at most.

After this time limit, it is not impossible for them to stay in the main world, but then they will need additional mana to maintain it.

Even with the glorious halo, after losing nearly a thousand Abyss Lords, the summoning limit and maintenance time suffered great losses.

Xu Lai was not able to take over the city of Kasai in one go. As a marquis' castle, the city of Kasai was built extremely magnificently.

After being transformed by the devil, the city of Kasai became easier to defend and more difficult to attack.

The moat was replaced by flowing lava. If you wade through it to attack the city, you will be scalded to death. In addition to the defenses on the ground, there are at least a dozen fire towers on the city walls, and each fire tower has at least 3-4 fire trolls.

The main tower was even more terrifying, as there was actually a fire demon inside, which he had come from nowhere.

As a spellcasting unit, even if it is just throwing fireballs, its range cannot compare to that of a shooter.

However, the Fire Demon Tower has two functions: one is to increase the range, and the other is to increase the power of the fireball.

Even with the Fire Demon Tower, Xu Lai was not very scared. After all, the range of the Phantom Shooter was even more terrifying.

But the enemy still has the city wall, the city wall plus the Fire Demon Tower, even if the Fu Tower is not as good as the Phantom Shooter, the Fire Demon on the main tower can definitely shoot back.

This fire demon was tested by the three water qilins using their last remaining heat.

Unfortunately, there are too few three-headed water unicorns.

After smashing thousands of horned demons on the city wall, as well as a dozen catapults and more than forty crossbows, he was killed by Mendis and the Balrog.

The good news is that Xu Lai doesn’t have to worry too much about the opponent’s city defense weapons.

Ferris has ultimate archery, ultimate ballistics, and the skill of crossbow, plus the range and power advantage of the city wall.

These more than 40 advanced crossbow carts are equivalent to at least 400 high-level troops, and they are long-range high-level troops.

The bad news is that the three water unicorns have used their lives to verify the defensive strength of Kasai City.

With Xu Lai's help, the three water qilins are almost invincible.

Xu Lai originally just wanted to use their last time to cover the army's siege on the city.

However, he didn't expect that the Water Qilin had been destroyed before his catapult was assembled and the main force had not yet joined the battle.

The more than 50 advanced crossbow carts on the city wall are extremely powerful with the support of ultimate archery and ballistics.

The Water Qilin tried its best but only destroyed more than 40 planes. The thousands of horned demons in charge of controlling them were just a bonus.

Although the city walls were temporarily cleared, Ferris' specialty was still making crossbows.

Due to limited materials, she could only make 5 or 60 high-end crossbows, but the number of ordinary crossbows of lower quality was definitely not small.

After comprehensive adjustments, even if the power of city defense weapons decreases, it will not be too much.

On Xu Lai's side, the main force is cavalry, and their siege capability is not strong.

As for the air force, because the Fire Elves were all wiped out and the Winged Demons suffered heavy losses, our side had an absolute advantage.

But once the air force is dispatched, unless it is conducting high-altitude reconnaissance, it still cannot avoid being shot at by the enemy's long-range forces.

Secondly, although our air force has certain advantages, it is relatively weak in terms of quantity.

The opponent has the help of Mendis and a large number of flying abyss demons and abyss lords.

They don't need air superiority, they just need to hold back Elvy and the others and prevent the angel troops from opening the city gates.

What's more, if Xu Lai only dispatched the air force, Elvy and the others would be caught in a fight, which would be quite dangerous.

There is no solution that will satisfy both parties, so Xu Lai will just delay it.

Anyway, he had a large number of cavalry troops and could roam freely across the entire Paphakes Plain.

Moreover, after the siege of Kasai, the castle gate of Kasai was no longer useful and could no longer be used to transport troops between castles.

Xu Lai didn't know that Mendis could use magic to turn the castle gate into the gate of hell.

But this had no effect on the battle situation.

During Xu Lai's siege of the city, the demons were unable to resist at all.

Ferris also knew that facing a powerful superhero like Xu Lai, no matter how many demons were stationed outside, they could only delay time.

Compared to humans, demons are actually very rare.

Therefore, Ferris was not willing to lose troops in vain. Her strategy was to leave only a small number of demons in each stronghold.

These demons used the city’s fortifications to counterattack the human forces and deplete their strength.

But unfortunately, Xu Lai has the Angel Legion here, as well as three super meat shields.

Not to mention that with the Water Qilin here, Xu Lai’s troops will not suffer any casualties.

Even if there are, as long as thousands of people don't die at once, they can all be pulled together in one night.

Because of this strategy, there are now a large number of demon troops in Kasai City, so many that they have become a serious burden.

In this situation, Ferris only hoped that the human troops could come and attack the city immediately, so that both sides would consume some troops.

Even if the consumption ratio is ten to one, Ferris is willing to do it.

The problem is that Xu Lai is not willing to do so.

For him, it was only a matter of time before he captured the Paphakes Plain.

In the entire plain, the only lonely city left is Kasai.

When Xu Lai had no advantage in the siege, he was so stupid as to waste human lives.

Avid finally sent a batch of catapults, but it turned out that not only could he not fight against the enemy's catapults, he couldn't even shoot past the enemy's crossbows.

If Xu Lai was the defender, if he really wanted to fight with the opponent in a consumption contest, he would definitely not be willing to use it even if he had an advantage in equipment.

He could even give up the city wall.

If you are unwilling to sacrifice your child, you cannot catch the wolf. If you are unwilling to put out any bait, how can you expect the fish to take the bait?

What's more, after taking over the Pafix Plain, Xu Lai was busy all day long.

There are dozens of cities, hundreds of towns, thousands of villages and resource points, and hundreds of rebel forces of varying strengths.

It is easy to take over these cities, but it is not so easy to govern them.

Although Xu Lai was conscious of training talents in echelons, he simply did not have enough time.

Not only was progress going smoothly for him, but Reina was also escorted by the Coast Guard, which had high-level infantry and archery units.

In addition, with the help of fearless summoned dragons in every battle, Reina was able to advance triumphantly and was invincible.

With so much land, we can’t just leave it vacant.

If we want to resume production, we must first have a sufficient population.

The damage caused by the demons to the Western Empire was extremely huge, especially the loss of manpower.

This made it extremely difficult for Xu Lai to restore the previous structure.

Many cities, even if they are recovered, can only remain vacant temporarily.

Some villages and towns simply had to be demolished first to concentrate resources as much as possible.

Xu Lai was forced into a corner and even thought of issuing tasks in the Mercenary Guild to recruit some advent heroes to resume production.

It's no wonder that these heroes who descended on the Earth dreamed of having their own territory. Even though the conditions proposed by Xu Lai were not very good, there were still many people who responded. (End of this chapter)
