Survival for the whole people: build mechas at the beginning, open Gundam

tens of thousands of meters above the sky.

There are tens of millions of flying arms circling the major alliances,

All of them hovered outside the magic defense shield, not daring to approach.

On the ground, there are tens of millions of land troops, who are isolated from the city wall that is several hundred meters high.

In fact, even the moat of the black technology castle blocked a large number of enemies.

The water in the moat is not ordinary river water.

Once an enemy falls into the river, it will sink to the bottom quickly, unable to climb up, and drowned directly.

Of course, the most powerful weapon to stop the enemy is the near-defense gun on the city wall.

Fully automatic close-in gun, unlimited ammo,
The rate of fire is more than 3000 rounds per second, even a tank can't hold it for a second,
These arms of the alliance approached the black technology castle at the beginning,

It was torn into a blood mist immediately, and no one was spared.

"Horse's!"

"I just can't understand it!"

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

"Why is the city wall of my primary main city less than 100 meters, but his city wall is as high as 400 meters!"

"Absolutely a high-level main city!"

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

"And what is that cannon! It can't be approached at all, how can it be fired?"

"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 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? Hurry up and pull it over!"

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

"..."

Just at this time.

On the walls of the black technology castle, clusters of eye-catching light shone.

Immediately afterwards, huge beams of light flew out,

It directly blasted into the alliance army in the city.

In an instant, there was a booming sound.

Like a thunderstorm!
At the same time, huge mushroom clouds appeared, filling the sky above the alliance army.

The whole battlefield fell silent,
A moment later, the alliance army was in chaos again.

Many castle owners retreated in fright, not daring to approach the walls of the black technology castle.

"Fuck!"

"There are magic cannons erected on the walls of the black technology castle, and the number is as high as several thousand!"

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

"Tang Xiaofan has captured so many dynasty-level forces, and has enough resources to upgrade the castle to a high-level main city. What's the point of building a few thousand magic cannons?"

"You're really a toad, yawning so loudly!"

"That's thousands of magic cannons!"

"One round of bombardment, our alliance army lost tens of thousands of units!"

"A few more times, the army camp will collapse immediately!"

Before the castle lords on the battlefield are overwhelmed,
On the walls of the black technology castle, there was another dense rain of arrows, hundreds of thousands of them.

Every time a rain of arrows falls, a large number of castle troops are shot and killed.

In the past few rounds, the alliance army has lost tens of thousands of units.

Then,

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

Caused greater casualties to the Alliance army.

"Slot!"

"I don't feel like I'm attacking the castle forces at all, but rather like attacking the giant city of the local empire. Such a defensive force is too frightening!"

"Haven't Tang Xiaofan's castle troops dispatched to attack the Dragon's Nest? Who is manipulating those mana cannons, giant crossbows, arrow towers, and crossbow camps?"

"My flying units discovered in the sky that there are still a large number of human races in the black technology castle, up to tens of thousands!"

"The population of the black tech castle is probably in the hundreds of thousands!"

"These human races were forcibly captured by Tang Xiaofan!"

"One hundred thousand arms, trough, crazy!"

"Shocking news, someone passed through the defensive shield and found three arms buildings!"

"Three arms buildings, how is it possible!"

"Nothing is impossible, besides the Demon Factory, Tang Xiaofan also has the Guangming Monastery!"

"Oh my God!"

"I don't know if I don't come, I'll be shocked!"

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

"The number of units 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 us top castle masters will have no way out!"

"The Ten Thousand Races Contest, I can't beat him at all!"

"Don't talk nonsense! Hurry up and order the army to continue the attack. If it's too late, Tang Xiaofan's castle army will almost come back! The two rubbish alliances, Mie Shen and Tu Shen, can't stop them within an hour."

"Kill! Go!"

As the order is passed down,
Tens of millions of troops from the major alliances once again frantically attacked the black technology castle.

There are still dense flying units in the sky, forcibly attacking the defensive magic shield arranged by the elf mother tree.

They disregarded the strong killing of the near-defense guns,
I want to risk my life to attack the magic shield.

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

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

Outside the black technology castle,
Hundreds of thousands of troops from the Alliance of the Gods, the Alliance of Killing Gods, the Alliance of Killing Gods, and the Alliance of Choosing Gods are also frantically attacking the walls of the black technology castle.

They even really moved the magic cannon in the rear castle.

Hundreds of magic cannons were lined up, and they blasted fiercely at the walls of the black technology castle.
It's a pity to guard against the attack of the near-defense artillery, they can't get too close, they can only attack from a distance.

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

After all, even if it is a level 21 powerhouse, it is not easy to destroy the walls of the black technology castle.

Not to mention a mere small magic cannon?
In fact, the power of the magic cannons on the Gods and Demons Continent is far lower than the magic cannons on the Sky City.

They are also small magic cannons.
The small magic cannon mounted on Sky City is enough to kill level 21 powerhouses, but the small magic cannons in the Gods and Demons Continent are not good enough, they can only kill level [-] powerhouses at most.

Such a big gap is entirely due to the more advanced magic cannon technology of the farmers.

After all, no matter what,
The city in the sky is a war fortress for the peasants to attack the world of the dimensional plane.

The magic energy cannon it carries is naturally not weak,
Especially the sacred magic cannon, which is powerful enough to kill the true god.

"It's useless to tell you a long time ago, but you don't believe it!"

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

"It's useless, you have to try!"

"Now, we must do everything possible to break through the wall defense of the black technology castle, or destroy the magic defense shield and enter the black technology castle!"

"The defense of the black technology castle is too strong, harder than a turtle shell!"

"What should we do now?"

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

"No one thought that Tang Xiaofan had already upgraded the black technology castle to a high-level main city!"

"His wall defense value is terrifyingly high!"
