At this moment, Lin Min and the others all rushed up, launching attacks on the enemies before them. Beams of light and missiles shot out, destroying a large number of them.

With the two IV-generation bio-mechanical armors leading the way, the group broke through with irresistible force.

....

Inside the underground central control room, Canon watched the real-time images being transmitted back, and was extremely furious.

"What's going on? Why can't so many elite troops stop them? Annihilate them! Quickly produce more soldiers for me!"

As Canon issued the order,

The production machinery in each factory started up, frantically holographic printing security guards and war guards.

Weapons were produced in batches and dispatched to the battlefield at the first possible moment.

Unfortunately, the effect wasn't good.

Su Mo's two IV-generation bio-mechanical armors were like sharp blades, cutting through the tide and blocking a large number of attacks. Lin Min and the others only needed to keep firing from behind.

They methodically approached the underground central palace.

Canon's red electronic eyes kept flashing, feeling a strange sense of panic.

"What about the advanced weapons!"

Canon began to use Artificial Intelligence·Hei Zhou to search for high-level weapons in stock.

Instantly, a row of directories popped up.

Strategic-class interstellar battleship·Black Swan (out of stock)

IV-generation standard pure mechanical armor·Guang Zhe (out of stock)

IV-generation War Destroyer (out of stock)

.....

Scanning all the way down, all that was visible were prompt boxes.

"Insufficient stock!"

"Insufficient stock!"

.....

All the high-level directory icons were grayed out, indicating that there were no products in stock.

However, from the directory, it could also be seen that the Hongji Empire was actually very powerful in the past, and could already mass-produce IV-generation pure mechanical standard armors, and even independently produce large battleships.

"Damn it, produce them!"

Canon issued an angry mechanical sound.

"Prompt: Insufficient raw materials....."

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

Canon kept searching for all the weapons within its permissions, and it tragically discovered that, apart from low-level arms, there were no high-level weapons at all.

The worst thing was that the defense weapons of the underground central base had been almost destroyed by itself.

As long as those guys broke in, they could march all the way to him.

Just then, Canon suddenly searched for a permission.

"Weapon Upgrade Modification (available)"

Canon's electronic eyes flashed red.

.....

On the other side, Su Mo and Qian Chengxue advanced rapidly, and soon they saw the central area of ​​the underground city, where a thousand-year-old imperial capital covering an area of ​​1,200 square kilometers stood.

"Target acquired."

Su Mo said in the communication channel with shock.

"Holy crap, it's so big!"

When Wei Teke and the others saw it, they also took a breath of cold air.

At this time, Gyan's voice rang in the communication channel: "This was built with the heritage of our Hongji Empire over thousands of years. Every building inside carries our years of history. And Artificial Intelligence·Hei Zhou is in the underground base at the bottom of that palace. Don't worry, that base is also a full hundred square kilometers, which can fully accommodate the battle of fourth-generation armors."

"Understood."

Su Mo and the others perked up their spirits. They were about to attack the opponent's lair. Who knew if many powerful enemies would pop up.

After a long time, Su Mo and the others successfully broke into the imperial capital amidst the tide of enemies, with a pile of mechanical wreckage behind them.

Entering the imperial capital, the surrounding buildings were no longer simply steel structures. Many wooden buildings, humanoid buildings, disc-shaped buildings, and various distinctive concrete buildings could be seen.

But it was a pity that a large part of these buildings had been damaged and decayed.

Of course, one could vaguely see how prosperous this place once was.

Of course, Su Mo and the others couldn't bother admiring these. They went straight to the central palace.

Because the number of attacking enemies was increasing,

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

It was only fortunate that the two armors of Su Mo and Qian Chengxue were very powerful.

Finally, Su Mo and the others successfully broke in.

A palace covering an area of ​​hundreds of kilometers, inlaid with various colored glaze and gemstones, and with various strange creature patterns carved on the outer walls, and incomparably luxurious came into view.

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

However, the gate was destroyed, and the entrance was a mess.

When Su Mo and the others saw this scene, they immediately noticed something was wrong. It was messy here, as if it had just experienced a battle.

"Let's go in."

Su Mo took the lead in driving the armor and rushed in, and Lin Min and others followed immediately.

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

The inside of the palace was extremely luxurious. Mechanical pillars with various patterns engraved on them went up to the roof.

The entire ground was covered with bright blue crystal bricks like mirrors.

The walls around and the ceiling above were all painted with colorful colored glaze paintings.

Gyan and others were filled with emotions when looking at their former home.

In the center of the palace, there was a huge damaged hole leading directly to the underground.

"Who on earth attacked here?"

Wei Teke asked suspiciously.

"We didn't see a single corpse along the way. It shouldn't be our people."

Lin Min said after looking carefully.

"Forget it, why bother so much? It's good to have someone to die for us and pave the way."

Wei Teke replied excitedly. He hadn't fought so happily in a long time, crushing all the way.

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

"Okay, let's go down."

Lin Min agreed.

"I'll go down first."

Su Mo drove the IV-generation bio-mechanical armor·Baoshi and took the lead to jump down.

Qian Chengxue followed without hesitation.

"Let's go too."

Everyone drove the Hyena armors and jumped down.

Soon Su Mo and the others landed in a very empty area, surrounded by the wreckage of destroyed security guards.

Kalinsha looked around and said, "This seems to be an underground mechanical reserve. There is a large passage in front, which should lead to the internal area."

"Well, but it doesn't seem so easy to get past."

Lin Min said solemnly.

Countless security guards and war guards emerged from all directions.

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

In the next second, they piled up in all directions without any blind spots.

"Don't worry about these small fries, leave them to us. Su Mo and Qian Chengxue, you break in first and see if you can directly take down that Artificial Intelligence·Hei Zhou."

Lin Min's words were not nonsense. Although Gyan said that Artificial Intelligence·Hei Zhou had a pseudo-V-generation armor in its hands, it still needed to be activated.

If they could get to him before it was activated, maybe they could stop him. It wasn't entirely impossible.

Su Mo and Qian Chengxue naturally understood what Lin Min meant. They drove their armors to explode with all their strength at the first possible moment and rushed towards the interior.
