Orlando gave the order, and all the heroes present were in good spirits.

They are second- or even third-generation elves who grew up listening to Orlando's teachings.

They had always heard that Orlando's secret weapon was powerful, but how powerful it was, they hadn't actually seen it.

As soon as Orlando's order arrived, they immediately lifted their spirits.

They all understood that it was Orlando looking for a legacy.

This time, whoever learns more will be the heir of Orlando.

So they all stared at Orlando's movements.

At this time, inside the Black Castle, the commander of the Black Castle Legion also felt uneasy.

But he didn't quite understand where the uneasiness came from.

He wanted to enter the deepest chamber of the Black Castle and activate the total defense of the Black Castle, but it was Nuren's forbidden place, which stored the chance for Nuren's resurrection.

With Nuren's personality, it was strictly guarded, and even he couldn't get in.

He can only keep moving his troops to prevent any enemy from sneaking into the Black Castle or something.

But this hero never imagined that there was an attack on the Black Castle, and the attack was not a sneaking enemy, but a thunderbolt falling from the sky.

When the hero ran into the interior of the Black Castle, a large cloud appeared in the sky of the Black Castle.

Purple, red, and dark green lightning danced in the clouds.

The lightning bolts turned out to form a huge eye.

The eyes were the same as the eyes that Nuren had used to observe his enemies.

It's just that there is no spirit in these eyes.

With his eyes fixed on the ground position of Blackcastle, this is Orlando's target.

Orlando's goal this time is to destroy the entire Black Castle, so his coordinates will be a little lower than the others.

This is even ruined.

After the coordinates were determined, the eyes in the sky also moved.

Then a bolt of lightning fell from the sky and landed on the Black Castle.

At this time, the people of the Black Castle Regiment also understood where the attack came from.

But by this time it was too late for them.

As Orlando said, the thunder and lightning that have accumulated for thousands of years are no longer something that ordinary people can stop.

As the first lightning fell, the second, third, thousands of lightning bolts chased down.

Because these lightning bolts don't have much wisdom control, they don't play some tricks in the sky, and they become thunderbirds and thunder dragons or something, but they hit directly downward.

As the lightning fell, Blackcastle also stood up for it.

But the defenses of Blackcastle were simply not able to withstand the power of lightning.

After all, the undead will also be restrained by thunder and lightning.

The most important thing is that in the place where the lightning struck, the temperature went up directly, although the Black Castle is an undead city, most of the city was transformed from the original human capital.

With the exception of the castle on the highest hill, which is made of stone, most of the buildings are made of wood and stone.

The stone is fine, but as long as the temperature is high, the wood will burn directly.

So under the first wave of lightning, the whole Black Castle burned.

At the same time, the undead on the surface of Blackcastle have all died under the thunder and lightning.

But even so, the thunder and lightning did not stop, and they continued to strike one after another.

If this is the case, there may not be a way to show the accumulation of millennia.

As the lightning increased, the lightning merged in pairs, and finally collided with each other, becoming even larger thunderbolts.

The elves in the distance were dumbfounded, they were clearly standing fifty miles away, but they could clearly feel the heat emitted by the thunder and lightning.

"Prepare to retreat, the thunder and lightning are a little out of control."

Orlando glanced up at the situation in front of him and gave the order directly.

Now that I've seen enough, if I continue to look at it, I may see myself together.

When the elves heard this, they immediately stepped back with Orlando.

Orlando's guess was not wrong, as the lightning bolts collided one by one, and all the lightning bolts finally formed a huge ball of lightning that fell directly from the sky.

The lightning ball wasn't too big when it looked at it in the sky, but when it fell, it enveloped Black Castle and all the cities in their city.

The ball of lightning landed on the ground, and a thud was heard.

The powerful shockwave directly blew around the center of Blackcastle.

Under the shockwave, everything was blown up.

The strong wind blew nearly a hundred meters from Black Castle.

The retreating elves were also affected, and were smashed to the ground by the trees and masonry blowing from behind.

When the shock wave dissipated, the elves looked back and found that everything had disappeared from the original location of the Black Castle and the city, leaving only a large crater about thirty meters deep in the original Black Castle.

There was nothing left here except the Great Pit, whether it was the mountain where Blackcastle was located before, the city below Blackcastle, or the woods outside Blackcastle.

When the aftermath of the explosion had cleared, Orlando told the elves to stop.

He glanced back at the devastation caused by the explosion and finally sighed.

"It's a little more powerful."

"My lord, you don't have to sigh, that natural emperor didn't use our secret weapon, it was his own loss, missed our blow, see how he fights the army of the undead."

"You." Orlando shook his head, "You still underestimate other people, that adult can change all this in a short period of time, it shows that he has real skills."

In the future, he will be our lord, and it is better for you to change your thinking.

Let's go, the Black Castle has been taken, and then we will go and block the passage of the undead invasion, this territory will have nothing to do with us, whether the elves can occupy a position in this territory in the future, it depends on you. ”

When several elven heroes heard this, they didn't dare to say anything more.

But they didn't have anything to worry about when it came to Orlando's assignment.

They came this time, but they took some of his troops from the Royal First Legion with them.

After Chen Gu's expansion, this army was about three times stronger than the original Elven First Legion.

Although they only brought a small part of them, their strength was already equivalent to the number of the original Elven First Legion.

With such a force in hand, and the undead army has already gone in the direction of the Holy Tree City, they have nothing to fear from the rest of the way.

At this time, Chen Gu and Nuren also knew that something had happened to Black Castle.

Nuren was in the Black Castle because his lifebox was destroyed by lightning this time.

And Chen Gu is because he got a hint from the system.

The Black Castle was destroyed, and he occupied more than ten cities in the territory, and his mission was completed.
