Super Invincible Devouring System

"Here is the core of the tactical base!" As he spoke, the guide pressed the device that appeared at some unknown time in his hand.

Chu Tiannan looked at it, and couldn't help muttering: "What is it? No response?"

Luo Er gave the other party a blank look, didn't say much, looked around with beautiful eyes, with a trace of curiosity and expectation.

Although she is a talented expert of the Hundred Schools Alliance, she naturally doesn't know much about the core area of ​​Jingzhou Base City.

Boom!

As soon as Chu Tiannan finished speaking, the entire mountaintop area suddenly shook. Although it was not as obvious as an earthquake, Chu Tiannan could feel it.

At this moment, a special mechanism is being opened on the top of the mountain!
I saw a special tunnel slowly opened in the open space in the center of the mountain top, as if the center was blooming, and this tunnel turned out to be straight down.

Of course, Chu Tiannan and Luo Er still don't know exactly how deep it can be, and they can only roughly see its extraordinary construction strength.

The guide led Chu Tiannan and Luo Er to the edge of the tunnel, and said with a smile, "Actually, the perimeter of this tactical base is to defend against monsters from outside."

"Monsters outside?" Chu Tiannan was taken aback when he heard the words, and couldn't help asking: "This is the strongest base city of the China League, how dare monsters come?"

Hearing this, the guide smiled proudly, and explained: "This is the last line of defense of our Chinese League, every base city has a tactical base, just in case, it can accommodate hundreds of millions of people, and it is also a refuge. "

Hearing this, Chu Tiannan suddenly came to his senses, and immediately nodded thoughtfully.

Yes, who can guarantee that the future base city will really exist forever?
If the monsters are really too strong and break through the base city, then this so-called tactical base may really be the last refuge of mankind.

"As expected of a tactical base in Jingzhou Base City, I really can't imagine this kind of construction wisdom," Chu Tiannan sighed.

"This tactical base is the place where Jingzhou Base City invests the most, because of its solidity, even the Supreme Being who surpasses Valkyrie cannot break through." The guide said proudly.

At this time, Chu Tiannan and Luo Er followed the guides to the empty plane in the tunnel, and swept down directly at a very fast speed.

The tunnels along the way are not that bare, but each floor has its own function.

"The first fifty floors of this tunnel are defense systems. The laser cannons here can kill king-level monsters in an instant, but the cost of consumption is too high, and there is no such thing as a Valkyrie." The guide explained.

As for Chu Tiannan, he looked around with great interest, and felt a little awe-inspiring when he saw the layers of ferocious and cold muzzles.

The laser cannon that can instantly kill king-level monsters is indeed a powerful technological weapon for humans.

"I've learned a lot." Luo Er said softly as she looked around with beautiful eyes shining brightly at this time.

As the unloaded aircraft continued to fall, Chu Tiannan saw the floors of the beautiful high-rise building outside the weapon system, his heart suddenly brightened, and he couldn't help muttering.

“It's too beautiful”

Luo Er nodded lightly, expressing her agreement with the former, because she really did not expect that human beings could actually install buildings underground.

What kind of vast project is this?
"The living area of ​​the tactical base is still under development. We, the Huameng, are holding the ground below. Soon the top ten bases will be connected underground. By then, it will be a real underground steel city fortress." The guide smiled.

"Underground city." Chu Tiannan murmured, human wisdom is really powerful, this kind of thinking can be called advanced.

"We're almost there!" The three of them fell for nearly half an hour before stopping at the open space at the bottom.

This is the place where all kinds of fighter planes and vehicles park together, Chu Tiannan and others got off the plane again.

"Unexpectedly, I am now close to the center of the earth." Chu Tiannan looked around curiously, looked at the majestic and majestic project, and sighed in his heart.

"My lords, please follow me. The Great Wall Guards are on the third floor above. We need to take the elevator up." As he spoke, the guide smiled and led the way.

The two of Chu Tiannan followed each other into the elevator, the elevator was extremely transparent, he asked the guide: "How long?"

"Soon!" The guide smiled mysteriously, and then, the transparent elevator slid, and there was no time for anyone to react.

Gone in an instant!
