Tens of millions of flying units from major alliances are hovering around,

They were all hovering outside the magic defense shield, not daring to get close.

On the ground, there are tens of millions of land troops, isolated outside the city wall that is hundreds of meters high.

Even the moat of the black technology castle blocked a large number of enemies.

The water in the moat is no ordinary river water.

Once an enemy falls into the river, he will sink to the bottom quickly, unable to get up, and will drown directly.

Of course, the most powerful weapon to stop the enemy is the close-range defense cannon on the city wall.

Fully automatic close-in defense guns, unlimited ammunition, and a rate of fire of more than 3,000 rounds per second. Even tanks cannot hold it for a second. When these alliance troops approached the black technology castle,

They were immediately torn into bloody mist, and no one was spared.

"Horse's!"

"I just can't understand it!"

"What level is Tang Xiaofan's black technology castle?"

"Why is it that the walls of my primary main city are less than one hundred meters high, while his walls are three to four hundred meters high!"

"It's definitely a high-end main city!"

"It is impossible for an intermediate-level main city to have a city wall of this size!"

"And what is that cannon! You can't get close at all, how can you shoot it?"

"Tang Xiaofan's development speed is more than ten times faster than ours, it's scary!"

"I just want to ask a question, how to break down a city wall that is hundreds of meters high?"

"I also want to ask a question, how to get close to the city wall? The artillery is too sharp!"

"I heard that someone in our alliance has built a magic cannon? Come over here quickly!"

"It's just a small magic cannon and it's useless at all!"

"..."

At this time.

On the walls of the black technology castle, dazzling lights shone.

Then huge beams of light flew out,

It blasted directly into the alliance army in the city.

In an instant, a roaring sound sounded.

Like thunder! At the same time, huge mushroom clouds appeared, filling the sky above the Alliance army.

The entire battlefield fell silent, and a moment later the Alliance army was in chaos.

Many castle owners were so frightened that they quickly retreated, not daring to get close to the walls of the black technology castle.

"Fuck!"

"The walls of the black technology castle are actually equipped with magic cannons, and there are thousands of them!"

"Crazy! Where did Tang Xiaofan get so many resources?"

"Tang Xiaofan has conquered so many dynasty-level forces and has so many resources that he has upgraded the castle to a high-end main city. What does it mean to build a few thousand magic cannons?"

"You really are a toad and yawn so loudly!"

"Those are thousands of magic cannons!"

"In one round of shelling, our alliance army lost tens of thousands of troops!"

"If you come here a few more times, the army camp will collapse!"

Before the castle lords on the battlefield were shocked, another dense rain of arrows appeared on the walls of the black technology castle, hundreds of thousands of them.

Every time a rain of arrows fell, a large number of castle soldiers were killed.

After a few rounds, the alliance army lost tens of thousands of troops.

Immediately afterwards,

The magic energy cannon on the city wall was fully charged, and a new round of bombardment began.

It caused greater casualties to the Alliance army.

"Gutter!"

"Why do I feel like I'm not attacking a castle force at all, but more like I'm attacking a giant city in the local empire. Such a defensive force is so terrifying!"

"Didn't Tang Xiaofan's castle troops dispatch all the troops to attack the dragon's nest? Who is controlling those magic cannons, giant crossbows, arrow towers, and crossbow camps?"

"My flying troops discovered in the sky that there are a large number of humans in the black technology castle, as many as tens of thousands!"

"The population of Black Technology Castle is probably one hundred thousand!"

"These human races were all forcibly abducted by Tang Xiaofan!"

"One hundred thousand troops, trough, crazy!"

"Breaking news, someone penetrated the defensive shield and discovered three military buildings!"

"Three military buildings, how is that possible!"

"Nothing is impossible. In addition to the Devil's Factory, Tang Xiaofan also has the Monastery of Light!"

"Oh my God!"

"I wouldn't know if I didn't come here, but I'll be shocked if I come here!"

"Tang Xiaofan alone has three military buildings, and they are all top military buildings!"

"The number of troops he can recruit every day is top-notch!"

"Tang Xiaofan's strength and potential are too terrifying. If we don't destroy his black technology castle, even top castle owners like us will have no way to survive!"

"You can't beat him in the Competition of All Races!"

"Don't talk nonsense! Hurry up and order the army to continue attacking. If it's a step too late, Tang Xiaofan's castle army will almost come back! The two rubbish alliances of God Destroyer and God Slaughter won't be able to stop them within an hour."

"Kill! Charge!"

As orders were passed on, tens of millions of troops from the major alliances once again madly attacked the black technology castle.

There are still densely packed flying troops high in the sky, forcibly attacking the defensive magic shield laid out by the Elf Mother Tree.

They ignored the strong damage from the close-range defense cannon and wanted to risk their lives to attack the magic shield.

They have only one purpose, which is to destroy the defensive magic shield and break into Tang Xiaofan's black technology castle.

As long as the Heart of the Castle is destroyed by them, even if Tang Xiaofan leads the castle army back, it will be too late, and they will have achieved one of the goals of this war.

Outside the Black Technology Castle, hundreds of thousands of troops from the Alliance of Gods, the Killing God Alliance, the God Killing Alliance, and the God-Chosen Alliance are also frantically attacking the walls of the Black Technology Castle.

They even actually moved the magic cannon from the castle behind.

Hundreds of magic cannons lined up in a row, blasting the walls of the black technology castle. Unfortunately, they had to be prepared for the attack of close-range defense cannons. They couldn't get too close and could only attack from a distance.

However, it is almost impossible to destroy the walls of a high-level main city with these small magic cannons.

After all, it is not easy for even a twenty-level expert to destroy the walls of the black technology castle.

What's more, it's just a small magic cannon? In fact, the power of the magic cannon in the Gods and Demons Continent is far lower than that of the magic cannon on the Sky City.

They are also small mana cannons. The small mana cannons mounted on the Sky City are enough to kill a twenty-level expert, but the small mana cannons of the Gods and Demons Continent are not good enough. They can only kill two people at most. A tenth level strong man.

The huge gap is entirely because the farmer clan's magic cannon technology is more advanced.

After all, no matter what, the Sky City is a war fortress for the farmers to attack the dimensional world.

The magic energy cannons it carries are naturally very powerful, especially the sacred magic energy cannon, which is powerful enough to kill the true god.

"I told you a long time ago that it's useless, but you don't believe it!"

"Hundreds of small magic cannons blasted together, not even knocking down the walls of the black technology castle, but wasting a lot of soul stones!"

"It's useless if it doesn't work, you have to try it!"

"Now, we must try every means to break through the black technology castle's wall defense, or destroy the magic defense shield and enter the black technology castle!"

"The defense of the black technology castle is so damn strong, it's harder to chew than a turtle shell!"

"What now?"

"The army of flying troops in the sky cannot destroy the magic defense shield, and the troops on land cannot break through the walls of the black technology castle."

"No one thought that Tang Xiaofan would have upgraded the black technology castle to a high-end main city!"
