At this time, Lin Ming and the others all rushed forward and launched an attack on the enemy in front of them, shooting out beams and missiles one after another, destroying a large number of enemies.

Under the opening of the way of the two Generation IV biological mechas, everyone broke through like a bamboo.

....

In the control room of the underground center, Canon looked at the images transmitted back in real time, and was extremely angry.

"What's the matter, why can't so many elite troops stop each other, destroy it for me, and produce more soldiers for me quickly!"

With the instructions given by Canon.

One by one, the production machinery of the arsenal is activated, and the crazy holographic printing security guards and war guards.

Pieces of weapons are produced, and the first is time to send them to the battlefield.

Unfortunately, it didn't work out well.

Su Mo's two IV generation biological mecha pierced into the splitting tide like a sharp blade, and also blocked a large number of attacks, Lin Ming and the others just had to keep attacking with fire behind them.

They methodically approached the central underground palace.

Canon's red electronic eyes flickered continuously, and he felt panic inexplicably.

"Where's the high-grade weapon?"

Canon began to use artificial intelligence to search for high-level weapons in inventory.

Suddenly, rows of directories popped up.

Strategic Star Battleship Black Swan (out of stock)

IV Pure Mechanical Mecha Light Fold (out of stock)

Generation IV Destroyer of War (no inventory)

.....

Sweeping all the way, I saw a prompt box.

"Out of stock!"

"Out of stock!"

.....

All premium catalog icons are gray to indicate that they are not in stock.

However, it can also be seen from the catalog that the Hongji Empire was actually very powerful, and it can already mass-produce the IV generation of pure mechanical mechas, and even independently produce large battleships.

"Damn it, give birth!"

Canon let out an angry mechanical sound.

"Hint: Insufficient raw materials ....."

"How is it possible, why is this happening, it's impossible, the weapons in the planetary fortress should be very strong, it is impossible that there are no high-level weapons...."

Canon kept searching for all the weapons within its authority, and it sadly found that there were no high-class weapons at all, except for the low-level troops.

The worst part is that the defense weapons of the underground hub base have been almost destroyed by himself.

As long as those guys burst in, they can triumphantly kill all the way in front of them.

That's when all of a sudden, Canon searched for a permission.

"Weapon Upgrade (Usable)"

Canon's electronic eyes flashed red.

.....

On the other side, Su Mo and Qianchengxue quickly rushed forward, and soon they saw that in the central area of the dungeon, there was a thousand-year-old imperial capital covering an area of 1,200 square kilometers.

"Discover the target."

Su Mo said in shock in the communication channel.

"It's so big!"

When Witco and the others saw it, they also took a breath of cool air.

At this time, Garn's voice sounded in the communication channel: "This is the construction of our Hongji Empire for thousands of years, and every building in it carries our years of history. And the Artificial Intelligence Black Sky is in the underground base at the bottom of that palace, you can rest assured that the base is also a hundred square kilometers, which can fully accommodate the battles of the next four generations of mechas. ”

"Understood."

Su Mo and the others cheered up one after another, and they were about to attack the other party's nest, and the ghost would know if there would be many strong enemies.

After a long time, Su Mo and the others successfully entered the imperial capital in the tide of enemies, and there were pieces of mechanical wreckage behind them.

When you enter the Imperial Capital, you can see many wooden buildings, humanoid buildings, saucer-shaped buildings, and various characteristic concrete buildings.

Unfortunately, a large part of these buildings are damaged and decayed.

Of course, you can vaguely see how prosperous this place once was.

Of course, Su Mo didn't care about appreciating these, and they went straight to the central palace to kill.

Due to the increasing number of enemies attacked.

Therefore, Su Mo's speed also slowed down, they were like swimming in a garbage pool, and the resistance was extremely disgusting.

It's just that the two mechas, Su Mo and Qianchengxue, are very powerful.

In the end, Su Mo and the others successfully entered it.

A palace that covers an area of more than 100 kilometers, is inlaid with various glasses and precious stones, and the outer walls are carved with various strange biological patterns, and the incomparably luxurious palace comes into view.

In the area of the main entrance of the palace, there is a gate made of special materials and hundreds of meters high.

However, the gate was destroyed, and the doorway was in shambles.

Su Mo and the others looked at this scene, and immediately noticed something unusual, there was chaos here, as if they had just experienced a battle.

"Let's go inside."

Su Mo took the lead in driving the mecha and rushed in, and Lin Ming and the others immediately followed.

After entering the palace, Su Mo and the others were dumbfounded.

The interior of the palace is not ordinarily luxurious, and mechanical pillars inscribed with various patterns lead to the roof.

The entire surface of the ground is paved with crystal bricks that are as bright as a mirror.

The surrounding walls and the ceiling overhead are all depicted with colorful glass paintings.

Jia Lan and the others looked at their former home, and everyone was full of emotion.

In the center of the palace was broken a large and broken hole, which went straight underground.

"Who the hell is attacking here?"

Witco asked, confused.

"I didn't see a single body on the way, it shouldn't be our people."

Lin Ming looked at it carefully and said.

"Forget it, no matter what you're doing so much, it's good to have a way to die."

Witko replied excitedly, he hadn't fought so well for a long time, and he had been crushed all the way.

You must know that in the previous battle, they were like rats, and they were thankful that they could catch their breath.

"Okay, let's go down."

Lin Ming agreed.

"I'll go down first."

Su Mo took the lead in driving the IV generation biological mecha Gluttony and jumped down.

Qianchengxue jumped down without a trace of hesitation.

"We'll go too."

Everyone drove the hunting mecha and jumped down one after another.

Soon, Su Mo and the others landed in a very empty area, and the wreckage of the security guards was destroyed everywhere around.

Karinsha looked around and said, "This seems to be an underground mechanical reserve, and there is a large passage in front of it, which should lead to the inner area. ”

"Well, it doesn't seem that easy, though."

Lin Ming said solemnly.

I saw countless security guards and war guards popping up in all directions.

Their red electronic eyes stared at Su Mo and the others.

In the next second, there are no dead ends in all directions.

"Don't care about these miscellaneous fish, leave it to us, Su Mo and Qianchengxue, you break in first, and see if you can directly take down that artificial intelligence black universe."

Lin Ming's words are not nonsense, although Garn said that the artificial intelligence Black Heaven has a pseudo-V generation mecha in his hand, but it must also be activated.

If you kill them in front of them before they start, you may be able to stop them, which is not completely impossible.

Su Mo and Qianchengxue naturally understood what Lin Ming meant, and they immediately drove the mecha to burst out with all their strength and rushed inside.
