At this time, Lin Ming and others all rushed forward and launched an attack on the enemy in front of them, shooting out beams and missiles, destroying a large number of enemies.
With the two IV-generation biological mechas opening the way, everyone rushed in like a rock.
....
In the underground central control room, Canon looked at the images transmitted back in real time and became extremely angry.
"What's going on? Why can't so many elite troops stop the opponent? Destroy it for me and produce more soldiers for me!"
Following the instructions given by Canon.
The production machinery of the arsenal was activated one by one, and security guards and war guards were printed frantically.
Pieces of weapons were produced and dispatched to the battlefield in the first place.
Unfortunately, the effect is not good.
Su Mo's two IV-generation biological mechas penetrated and split the tide like sharp blades, and also blocked a large number of attacks. Lin Ming and others only had to keep attacking behind them.
They approached the underground central palace in an orderly manner.
Canon's red electronic eyes kept flashing, feeling inexplicably panicked.
"Where are the advanced weapons!"
Kanon began to use artificial intelligence, Kurozu, to search for advanced weapons in stock.
Suddenly rows of directories popped up.
Strategic-class star battleship·Black Swan (out of stock)
IV generation pure mechanical mecha·Light folding (out of stock)
Generation IV War Destroyer (out of stock)
.....
Scan all the way and you will see prompt boxes one after another.
"Inventory shortage!"
"Inventory shortage!"
.....
All premium catalog icons are gray, indicating they are out of stock.
However, it can also be seen from the catalog that the Acer Empire was actually very powerful at one time, and could already mass-produce IV-generation purely mechanical mechas, and could even independently produce large battleships.
"Damn it, production!"
The canon makes an angry mechanical sound.
"Tip: 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's impossible not to have advanced weapons..."
The canon kept searching for all the weapons within its authority, and it sadly discovered that except for the lower-level arms, there were no weapons for the higher-level arms.
The worst part is that the defensive weapons of the underground central base were almost destroyed by himself.
As long as those guys rush in, they can triumphantly fight their way to him.
At this moment, suddenly Canon searched for a permission.
"Weapon upgrade (available)"
The Xanon electronic eye flashes red.
.....
On the other side, Su Mo and Qian Chengxue rushed in quickly, and soon they saw the center of the underground city, where a thousand-year-old imperial capital covering an area of 1,200 square kilometers stood.
"Discover the target."
Su Mo said in the communication channel in shock.
"Damn it, it's so big!"
Witko and others also took a breath after seeing it.
At this time, Jia En's voice sounded in the communication channel: "This is built by our Acer Empire for thousands of years. Every building in it carries our history. And the artificial intelligence Black Zhou is in that palace
In the underground base at the bottom, you can rest assured that the base covers hundreds of square kilometers and can fully accommodate the battles of the fourth generation of mechas."
"Understood."
Su Mo and others cheered up and were about to attack the opponent's lair. The ghost would know if many powerful enemies would appear.
After a long time, Su Mo and others successfully fought their way into the imperial capital amid the tide of enemies, with pieces of mechanical wreckage behind them.
Entering the imperial capital, the surrounding buildings are no longer simply made of steel. You can see many wooden buildings, human-shaped buildings, dish-shaped buildings, and various characteristic concrete buildings.
Unfortunately, most of these buildings are damaged and decayed.
Of course, you can vaguely see how prosperous this place used to be.
Of course, Su Mo and the others didn't care to appreciate these, they went straight towards the central palace to kill.
As the number of enemies attacked increased.
Therefore, Su Mo's speed also slowed down. They were like swimming in a garbage pool, and the resistance was extremely disgusting.
Fortunately, the two mechas Su Mo and Qian Chengxue are very powerful.
In the end, Su Mo and the others succeeded in fighting their way in.
An extremely luxurious palace that covers an area of hundreds of kilometers, is inlaid with various colored glazes and gems, and has various strange biological patterns carved on the outer walls.
In the main entrance area of the palace, there is a gate made of special materials and hundreds of meters high.
However, the gate was destroyed and the entrance was in a mess.
Su Mo and others looked at this scene and immediately noticed something strange. The place was in a mess, as if they had just experienced a battle.
"Let's go in."
Su Mo took the lead in rushing in with his mecha, and Lin Ming and others immediately followed.
After entering the palace, Su Mo and others were dumbfounded.
The interior of the palace is not ordinary luxurious, with mechanical pillars engraved with various patterns reaching up to the roof.
The entire floor is paved with blue crystal tiles that are as bright as a mirror.
The surrounding walls and the ceiling above are all carved with colorful glass paintings.
Jialan and others looked at their former home, and everyone was filled with emotion.
There was a huge, damaged hole in the center of the palace, leading directly to the underground.
"Who is attacking here?"
Witko asked doubtfully.
"I didn't see a single body along the way. It shouldn't be one of ours."
Lin Ming looked at it carefully and said.
"Forget it, no matter what, it's better to have someone die to clear the way."
Witko replied excitedly, he hadn't felt so good fighting in a long time, crushing him all the way.
You should know that the previous battle had made them look like mice, so it was a blessing to be able to take a breather.
"Okay, let's go down."
Lin Ming agreed.
"I'll go down first."
Su Mo took the lead and jumped down driving the IV-generation biological mecha Gluttony.
Qian Chengxue jumped down without any hesitation.
"We're coming too."
Everyone jumped down one after another while driving the Hyena Mecha.
Soon Su Mo and others landed in a very empty area, surrounded by the remains of damaged security guards.
Karinsha looked around and said: "This seems to be an underground mechanical storage warehouse. There is a large passage in front, which should lead to the internal area."
"Yeah, but it doesn't seem to be that easy to get over."
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 others.
The next second, they piled up from all directions without any blind spots.
"Ignore these miscellaneous fish, leave it to us, Su Mo and Qian Chengxue, you guys rush in first and see if you can directly take down the artificial intelligence Black Zhou."
Lin Ming's words are not nonsense. Although Jian En said that the artificial intelligence Black Zhou has a pseudo V-generation mecha, it still needs to be activated.
If you get in front of it before it activates, you might be able to stop the opponent. This is not impossible.
Su Mo and Qian Chengxue naturally understood what Lin Ming meant. They immediately drove the mecha with full force and rushed inside.
