"This is the core of the tactical base!" As he said this, the leader pressed the instrument that appeared in his hand from unknown time.
Chu Tiannan looked at it and couldn't help but muttered, "What the hell? No response?"
Luo'er rolled his eyes at the other party and said nothing more. His beautiful eyes looked around with a hint of curiosity and expectation.
Although she is a powerful genius of the Hundred Families 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 special mechanism is opening on the top of the mountain!
I saw that in the open space in the center of the top of the mountain, as if there was a flower blooming in the center, a special tunnel slowly opened, and this tunnel actually led straight down.
Of course, the specific depth of Chu Tiannan and Luo'er is not clear yet. We can only roughly see their extraordinary construction capabilities.
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 designed to resist Demon Beast from the outside world."
"Demon Beast on the periphery?" Chu Tiannan looked startled when he heard this, and couldn't help but ask, "This is China Alliance's strongest base city, Demon Beast dares to come?"
Hearing this, the leader smiled proudly and explained, "This is our China Alliance's last line of defense. 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 Demon Beast 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 Jingzhou Base City's tactical base. I really can't imagine this kind of construction wisdom..." Chu Tiannan sighed.
"This tactical base is where Jingzhou Base City has invested the most. Because of its solidity, even the supreme being that surpasses Martial God cannot break it." The leader said proudly.
At this time, Chu Tiannan and Luo'er followed the leader to the back of the unloaded 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 cannon here can instantly kill King Level Demon Beast, but the cost is too high and it is not as effective as Martial God." The guide explained.
Chu Tiannan looked around with interest, and felt a little awe-inspiring when he saw the layers of ferocious and cold muzzles.
A laser cannon that can instantly kill King Level Demon Beast... Human technological weapons are indeed powerful.
"I have learned so much." 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 beautiful floors of a high-rise building outside the weapon system. His heart suddenly lit up and he couldn't help but murmur.
"This is so beautiful..."
Luo'er nodded slightly, expressing her agreement with the former, because she really didn't expect that humans could actually install a building underground.
What a huge project this must be?
"The current tactical base survival area is still under development. Our China Alliance is now digging up soil below. Soon the ten bases will be connected underground. By then, it will be a real underground steel city fortress." 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, and sighed in his heart for the miraculous workmanship.
"Two adults, please follow me. Great Wall Guard is on the 300th floor above. We need to take the elevator up." As he said this, the conductor 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!
