The Invincible Overlord of Heroes.

The use of the Abyss Gate has been suspended. Without the physical Abyss Gate, the cost for the Abyss Lords to summon hell creatures is much higher.

But at this time, Mendis also took into account the cost. Patton opened all the warehouses, and the mana potions and physical potions were available for him to use.

After careful consideration, Mendis chose to summon a fire spirit with the ability to fly.

Although Hellfire is better at group attacks, it is also more tough and resilient.

But one thing is that the Hellfire moves relatively slowly, and the human troops are deployed three kilometers outside the city.

At such a long distance, the firepower of the long-range troops alone can consume all the hellfire they summoned.

The Abyss Lord is summoned through the Abyss Gate. The cost varies depending on the summoned object.

The health of the Hellfire is much higher than that of the Fire Spirit, and it consumes more mana.

On average, if you summon two Hellfires, you can summon three Fire Spirits.

As daylight rose, the demons on the city wall saw more catapults than yesterday.

However, this time, the demons did not hide in the city, but sent out a large number of fire elves.

As an air force, the Fire Elves fly extremely fast and have been blessed with attack acceleration in advance.

These fire elves filled the entire sky and flew everywhere.

After the Qingfeng Legion's troops were merged, the number of archer troops was extremely large, already exceeding 5, and this was without counting the cavalry archers.

A large number of arrows fell like a flood, and countless fire elves fell.

However, these fire elves were not afraid of death at all, and still stubbornly flew towards the human catapult positions.

Xu Lai cast the magic of fire control in time. With this spell and resistance, as well as the anti-magic cloak, the damage of the fire spirit was extremely low.

But these fire elves had no interest in the crossbowmen on the ground. They mainly attacked the catapults.

As a machine, the catapult cannot be affected by the magic of fire control, resistance is ineffective against it, and the sacred blood bottle cannot increase its durability.

Although the archers and crossbowmen kept shooting arrows with the help of Xu Lai's amazing speed.

Unfortunately, these fire elves are all summoned units. They are not afraid of life or death at all, and they do not lose morale even if they die.

With the ultimate offensive technique, the Fire Spirit's destructive power against catapults is still extremely strong.

More than half an hour later, with the help of the Phantom Shooter, the fire elves that went out to fight were basically wiped out.

However, about 70% of this batch of catapults were also damaged.

Even if some of them could still hold on and be used after rescue, at least half of the catapults could no longer be fired.

But even if only half of it is usable, humans still have the upper hand.

After a whole day of bombardment yesterday, both the city walls and catapults on the Hell side suffered heavy losses.

Apart from tearing down the east wall to repair the west wall, their construction and repair speed could not keep up with Xu Lai at all.

At around three o'clock in the afternoon, the demons in Briston had almost no strength to fight back.

Of course, at this time, Xu Lai only had 5 or 6 catapults left.

However, these 5 or 6 catapults do not have to worry about the artillery fire from the city walls.

Crossbowmen can take their time to aim, and with the help of ballistics, their hit rate is greatly improved.

Even at night, the artillery fire did not stop.

Anyway, even if it is dark, it will not change the position and distance between the two sides.

The crossbowmen had been firing all day long, so they wouldn't miss any targets at night.

As long as he can hit the target, Xu Lai is not afraid even if it means wasting a little more ammunition.

What he has to fight for now is time, as no one knows when Kerrigan will come back.

Even when the Fire Spirits went out of the city to fight, Xu Lai did not send out the Seraphim because he had already sent Elvy and her angel army out.

Taking advantage of her high altitude vision and speed, Elvy was able to discover Kerrigan's pursuit in advance and escape.

Xu Lai was able to get notified in advance and could respond early.

If there is enough time, he can use the time and space gate to take the large army away.

If it is too late, he will have to make choices and decisions in time, whether to fight to the death or to fight and retreat.

No matter what choice he makes, time is very important to Xu Lai.

A night battle is inevitable, but he had not planned to start a night battle so early.

He was planning to start the siege in a day or two and take it down in one go.

When facing Briston, we certainly can't train our troops slowly like we did in Little Graycastle.

All the lights were turned off on the walls of Briston.

A large group of human craftsmen were forced to climb the city walls.

After a whole day of heavy bombing, especially in the final hours of the afternoon, entire sections of the city wall were in danger.

At the city gate, which was the focus of attention, the gate tower had been blown to pieces, and several nearby fire demon towers were also affected.

If it weren't for Briston, the magic circle that reduced the damage of siege equipment was still in effect, and the city gate might have been blasted open long ago.

Although it has not collapsed yet, it is already shaky and looks like it will collapse at any time.

This time, Xu Lai did not spend too much energy on defense towers such as arrow towers, turrets, and fire demon towers.

With the help of these defense towers, the fire demon's range will be greatly improved, and long-range attacks will have many advantages.

But Xu Lai planned to concentrate his firepower to destroy the city wall first.

Without the city walls, he could mobilize his infantry at any time and rush into the city to engage in street fighting.

Or, if he still had some strength to spare, he could use the catapult to target the Fire Demon Towers one by one and it wouldn't take him too much time to destroy them.

No one knows when the city wall, which is being targeted, will collapse.

Especially at night, Xu Lai began to tinker with the rings in his warehouse again.

Take out the catapults, accessories, ammunition, etc. that have accumulated in Qingfeng City throughout the day one by one, and then equip them into a complete catapult.

The crossbowmen who were injured during the day were rotated for treatment, and the fallen soldiers were resurrected if necessary, and buried on the spot if they could not be resurrected.

It’s not that Xu Lai doesn’t respect the deceased, nor is it that he doesn’t want to bring the body to the family.

The intact corpses had all been resurrected by the angels, and the remaining ones could not even be put together completely.

The Seraphim of the night do not have the ability of night vision and are unable to patrol.

It just so happens that they are also needed to resurrect the soldiers who died in the daytime.

The night patrol work was handed over to the dragon knight Sir Eric.

The black dragon living in the dungeon has dark vision and can see clearly even at night.

After advancing to the 9th level dragon knight, the speed is much faster than that of ordinary black dragons, and with Xu Lai's speed talent blessing. At least within the coverage range of Xu Lai's hero attribute, Xu Lai does not have to worry about Eric being alone and in any danger.

Even if they encounter Kerrigan's large army, Xu Lai and his men can use the space-time gate to leave, and Eric alone has a great chance of escaping.

On the contrary, if Pegasus Knights such as Ed and Silver Wing were also sent out, danger would be more likely to occur.

As catapults were assembled one after another, the firepower outside the city became stronger, and the human craftsmen responsible for maintenance inside and outside the city walls became more terrified.

Not only did they have to repair the city walls in the dark, but they also had to withstand the long-range firepower from their own people outside the city.

Even if they were smashed to death, not only would they have to bear the stigma of rapist, but their wives and children would also become food for the devil in an instant.

But if they don't do it, the long-horned warlords and evil gods in charge of supervision will whip them with those thorny whips without hesitation.

At this point when their true colors are revealed, the demons are too lazy to even maintain the last bit of warmth.

In this state, even if there is a demon whipping you from behind, how effective can it be?

The workers' maintenance efficiency was low, but the firepower outside the city continued to increase.

Finally, before the humans had a chance to have dinner, a section of the city wall collapsed.

Fortunately, on this section of the city wall, except for the maintenance workers and the demons in charge of supervision, even the fire demons and fire trolls in charge of defense had retreated.

Demons also value their lives. No fool would be willing to stay on such a precarious wall unless forced to.

This section of the city wall is like the first domino.

Once it collapses, the vibration and falling debris will hit other sections of the city wall, which is likely to cause a chain reaction.

As soon as the rumbling sound of the first section of the city wall collapsed was heard, Xu Lai ordered all the magic lamps and bonfires in the entire camp to be lit up.

The demons' city defense firepower had been destroyed by him.

Therefore, no matter how bright your own camp is, you don’t have to worry about becoming a target in the dark.

However, no matter how bright the camp was, it couldn’t reach Briston.

Xu Lai simply asked people to bring out the incendiary bombs. Since this type of ammunition causes fire damage, it is not enough to kill demons.

Moreover, as a magical ammunition, the damage caused by incendiary bombs to physical city walls is far less than that caused by solid stone bullets.

Therefore, Xu Lai not only did not use the incendiary bomb, but he also did not use any other magic ammunition.

At this time, changing to inflammable bombs to attack is not for killing the enemy, but simply for lighting.

Just like the tracer bullets in modern artillery fire, they are used to make it possible to see the trajectory of the ballistic projectile clearly in the dark.

The purpose of the incendiary bombs is to wait for the ammunition to explode so that people outside the city can observe the specific situation of Briston.

Moreover, the newly built catapult was still placed in the same position as during the day.

But no matter how you adjust it, there will still be a slight difference from the position during the day.

As the saying goes, a miss is as good as a mile. Every slight adjustment means a difference of dozens or even hundreds of meters.

Using the fire from the incendiary bomb, you can also adjust the direction and angle of the catapult.

At the same time, the collapse of the city wall also alarmed the demon bosses who had just laid down and were about to rest.

One by one, the demon generals crawled out from their tents or dreams.

The fire demon stationed in the Fire Demon Tower screamed in fear: "The city wall has collapsed, the city wall has collapsed!"

The city wall collapsed, but Xu Lai did not rush to order an attack. Instead, he launched more catapults and continued to bombard the city.

The infantrymen of the Qingfeng Legion, who had eaten and drunk their fill, returned to their respective barracks to rest under the orders of their respective superiors.

If the demons dared to rush out and fight Xu Lai to the death at this time, they might really catch Xu Lai off guard.

Unfortunately, the demons themselves also need to rest.

Moreover, from top to bottom, all the demons, including the fire demon Barton, do not have the confidence to fight against humans.

Nearly ten thousand abyss lords consumed countless mana potions and spent an entire night to summon the fire spirits.

It only took humans more than half an hour, relying only on long-range troops, to resolve the issue.

It is said that the Knights Templar, known as the strongest human cavalry regiment, has not taken any action so far.

Before the demons could come up with a countermeasure, the second section of the city wall collapsed under the continuous bombardment of catapults outside the city.

Then in the third and fourth paragraphs, Xu Lai seemed to be intending to tear down all the walls of Briston.

Patton gave the order, commanding all the combat demons to be attentive and take turns to rest in batches.

Outside the city of Briston, there is a lava moat.

Although this lava river cannot be compared with the magma in a volcano, its temperature is also terrifyingly high.

The most important thing is that ordinary wooden boards, even those that are only a few dozen centimeters thick, will immediately catch fire if placed on both sides of a lava river.

It takes less than ten minutes to cross a thick wooden board, and even less time for a person to cross it.

Once the wooden planks burn off, the soldiers crossing the river will fall into the lava river and it will be difficult for them to survive.

Of course, Xu Lai can also give them the magic of fire control. As long as the spell is not dispelled, it will be no problem for the warriors with thick blood to swim across the lava river.

If you want to avoid easy wear and tear, simple and easy-to-use props for crossing the river such as wooden boards are obviously not suitable.

Patton obviously also took the existence of the moat into consideration, so he deployed heavy troops for defense at the only city gate that could safely pass through the moat.

With the help of the fire from the fire bomb, Xu Lai saw a large number of long-horned generals, evil god kings, as well as lava trolls, fire demons, etc. gathered on the nearby fire demon tower.

Patton really spent a lot of money. Although Xu Lai didn't see it, he guessed that there should be a large number of big demons hiding nearby.

Only this kind of terrifying creature can rush to the battlefield to provide support in an instant.

However, Xu Lai was not in a hurry. He calmly commanded the catapults to carry out targeted elimination of the enemy's long-range firepower.

At the same time, he also asked Lena to use the Dragon Heart to summon dozens of skull dragons to help in the battle.

Xu Lai did not expect that the Dragon Heart would summon even the Bone Dragon.

This thing is an undead unit. If you carry it with you, it will seriously affect morale.

However, although these bone dragons are a little weak, they can still be summoned in large numbers.

With the help of Reina's defensive expertise, the demons were also slightly shocked.

Xu Lai has god-level offensive skills, which also come with the special effect of being invincible. Even the soldiers of the same level under his command find it difficult to defeat Lena's men.

Now, these bone dragons not only possess Lena's defensive expertise, but also Commander Xu Lai's speed talent, sacred blood bottle, and god-level offensive skills.

The bone dragon, which was originally extremely fragile and could be considered the weakest high-level creature, suddenly had its defense, attack, life, and speed data supplemented.

As an undead creature, the attacks of the bone dragon are accompanied by curses, and even after the bone dragon dies, it will take a very long time for the curse to dissipate.

Therefore, these dozens of skull dragons caused great trouble to the demon army.

Especially since they are flying creatures, they fly around and cause trouble everywhere, making all the demons in Briston restless. (End of this chapter)
