Super invincible swallowing system

"This is the core of the tactical base!" As he said this, the leader pressed the instrument that appeared in his hand at an unknown time.

Chu Tiannan looked at it and couldn't help but muttered: "What the hell? No response?"

Luo'er rolled her eyes at the other person and said nothing more. Her beautiful eyes looked around with a hint of curiosity and expectation.

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

Boom!

Just 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 time, some kind of special mechanism is opening on the top of the mountain!

I saw that in the open space in the center of the mountain top, as if there was a flower blooming in the center, a special tunnel slowly opened, and this tunnel actually led straight down.

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

The leader 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 resist the monsters from the outside world."

"Monsters on the periphery?" Chu Tiannan looked startled when he heard this, and couldn't help but ask: "This is the strongest base city in the Chinese Alliance. How dare the monsters come?"

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

Chu Tiannan suddenly came to his senses after hearing this, and then nodded thoughtfully.

Yes, who can guarantee that the future base city will really exist forever?

If the monster is really too strong and breaks through the base city, then this so-called tactical base may really be the last refuge of mankind.

"It is indeed a tactical base in Jingzhou Base City. I 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 the God of War cannot break it." The leader said proudly.

At this time, Chu Tiannan and Luo Er followed the leader to the back of the empty aircraft in the tunnel, and swept directly downwards at a very fast speed.

The tunnels along the way are not bare. Instead, each layer has its own function.

"The first fifty floors of this tunnel are defense systems. The laser cannons here can instantly kill king-level monsters, but the cost is too high and not as effective as the God of War." The guide explained.

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

Laser cannons that can instantly kill king-level monsters. Human technological weapons are indeed powerful.

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

As the unloaded aircraft continued to fall, Chu Tiannan saw the floors of a beautiful high-rise building outside the weapon system. His heart suddenly lit up and he couldn't help but mutter.

“This is so beautiful”

Luo'er nodded slightly and agreed with the former's words, because she really didn't expect that humans could actually install the building underground.

What a vast project this must be?

"The current tactical base survival area is still under development. Our Chinese League is now digging up soil below. Soon the ten bases will be connected underground. By then, they will be real underground steel city fortresses." The leader smiled.

"Underground city." Chu Tiannan murmured. Human wisdom is indeed powerful. This kind of thinking can be called advanced.

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

This is a place where various fighter planes and vehicles park together. Chu Tiannan and others got off the plane again.

"I didn't expect that I am now close to the center of the earth." Chu Tiannan looked around curiously, looking at the magnificent and majestic project, sighing at the miraculous workmanship.

"Two adults, please follow me. The Great Wall Guards are on the 300th floor above. We need to take the elevator up." As he said that, the guide led the group with a smile.

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 was rubbed, and there was no time for anyone to react.

Gone in an instant!
