Chapter 662 The Dark World

Author: Why I am a God

"More than a thousand kilometers, two hours?"

Xu Xin repeated it.

Xu Ying also looked at the man: "The speed is 500 kilometers per hour. This speed is not slow at all in the underground world. Are you... ready for us the tools we want to take?"

"certainly."

The man nodded.

"Since you are responsible for providing you with a location, you will naturally send the Buddha to the west. In the underground world directly below this world tree, we have placed a flight shuttle. You can take this flight shuttle and move forward in the underground world."

Flying shuttle...

Xu Xin thought of the aircraft army that was fifty or sixty kilometers away, like flying insects when he left the World Tree.

Could it be that kind of aircraft?

"What you provide is an alien invader's aircraft." Shi Wanyun asked, "Will the other party really not notice it when using this aircraft?"

Can the military equipment of alien invaders be used at will?

"Don't worry about this. This aircraft is used by our organization." The man explained.

"This aircraft was actually a aircraft that was scrapped due to a failure a hundred years ago. We did not scrap it, but after collection, it was modified. The positioning device has long been removed and many counter-positioning devices are installed on it. It may not be able to escape the tracking of alien invaders above the ground, but it is completely fine in this underground world, as long as you don't get too close to their base.

Members of our organization used this method to travel between the underground world, interacting and contacting for hundreds of years, and have never been discovered by the 'order defenders' or alien invaders, so you can rest assured."

So that's it.

Xu Xin nodded.

The "organization" that men call is the "rebels" in this time and space. Because their power is too weak, they can only communicate secretly underground for thousands of years.

They don't even dare to use communications because all remote communications require the use of alien invaders' satellites, and they are likely to be intercepted and eavesdropped by the "order defenders". So over the past thousand years, they have developed a skill that can come and go without a trace in the underground world.

"You are so amazing..." Xu Ying expressed surprise at the methods of the rebels in this world, and then asked, "Why didn't you tell us when you talked to you last time?"

"I didn't trust you completely when I talked to you last time." The man said, "Don't you not trust me completely?"

That's true.

The conversation between the two sides was actually not pleasant at the time, and there was basically no consensus at first.

Fortunately, Xu Xin and the others later found a monster and asked it to connect the bridge between the two sides.

When the man saw that the monster could speak and communicate stably, he couldn't believe what he saw.

Later, the two sides exchanged some information and finally reached an agreement.

"Although I can't believe that you will succeed now, the alien invaders have indeed driven their troops, and everything is like you said." The man said, "That's why we decided to spare no effort to help you. Of course, you should not expose us as you said before. We naturally have to leave a way out for ourselves."

As long as they are not exposed, even if Xu Xin and the others fail, they can still survive.

"Don't worry, it's not good for us to expose you." Xu Xin waved his hand, "Since that's the case, we won't waste much time. Let's go now. Shi Wanyun, you..."

Shi Wanyun whispered: "I will do what I should do. You must be careful."

Shi Wanyun's ability has nothing to do with fighting, so he naturally would not go with Xu Xin and the others.

However, Shi Wanyun is the holder of this world tree.

And here is surrounded by the vast sea. For alien invaders, this is definitely a place they don’t want to come at all.

Therefore, this is also their retreat.

If Xu Xin and the others fail, Ji Chaoyang and the others will no longer have the meaning of continuing to persevere.

Then they can directly transfer from the world tree to the world tree.

They are not trying to do this, they must leave a way out for everything.

When Xu Xin came last time, she had already set up the coordinates here and connected with the world tree.

Although the phase difference between inside and outside the world tree is very poor and cannot be communicated and transmitted, as long as the internal and external time flow velocity is adjusted to the same, transmission and communication can be achieved.

In other words, once Xu Xin and the others fail, or Ji Chaoyang and the others can't hold on, they will directly adjust the flow rate difference and then transfer all the people in the world tree to this island.

At this time, the owner of Shi Wanyun, the world tree, needs to receive the personnel.

Of course, if this happens, it doesn’t mean that Xu Xin and the others have abandoned the world tree with a strong time difference.

Even if the world tree over there cannot be kept, it will only be injected with toxins by alien invaders, causing it to wither completely.

But the time for withering is limited, and it won't take long to grow again due to its powerful root system.

Alien invaders do not have access to the world tree, so they cannot use that world tree.

In other words, when the storm passes, Xu Xin and the others can still find a time to return to the world tree.

This is the retreat they prepared for themselves.

It is not advisable to burn the boat, because there is too much difference between the two sides, both strength and information.

The winning chance is not big, and burning the boats is equivalent to semi-suicide, which is meaningless. Modern warfare is not something that can be solved by morale.

"Okay." Xu Xin nodded, "Be prepared at all times, it may not be possible for a long time there."

"I'll send you to the underground world."

Soon, a few people came to the underground world through the root lift of the World Tree.

The underground world here is located under the entire deep sea.

Moreover, because there are no crystal veins here, the underground world is pitch black.

When Xu Xin and the others walked out of the root elevator of the World Tree, they were completely unable to see their five fingers.

He took out a tree house core at the first time and illuminated the surroundings.

But the range that can be illuminated is only a few dozen meters around.

There is no soil on the rocky terrain, and the surroundings are extremely quiet, like a dark abyss, which is so quiet that it makes people frighten.

This is completely different from the underground world where monsters are everywhere and terrifying monsters he has seen before.

This is an unexplored dark world.

"After all, this place is relatively close to the base of the alien invaders, only more than a thousand kilometers. They did not conduct experiments on the giant beasts here." The man explained to Xu Xin and the others again, "And there are no crystal mines nearby, so except for the location very close to their base, they are basically in the undeveloped stage."

Before the man finished speaking, suddenly, two cylindrical strong lights were shot out at a distance of about two hundred meters away from the few people, illuminating the nearby area.

Xu Xin and Xu Ying also saw the source of the strong light.

It is exactly what men call flying shuttle.

"Is this what you are talking about? It's so small..." Xu Ying complained, standing next to the flight shuttle.

This is a very small aircraft with three propellers on the left and right.

The interior space is very small, and except for the driving position, there are only four or five people sitting behind.

The interior space of cars and small helicopters is almost the same.

However, the propeller is indeed very large, and the length of each propeller is longer than that of the cabin.

It looks like a large remote-controlled drone.

"This is our flight shuttle, this is the version suitable for the underground world." The man walked to the flight shuttle, "It's not fast, but it's very flexible, and it's very suitable for shuttles in some areas with complex terrain in the underground world."

As he said that, the man opened the hatch door and entered the cockpit: "You can't drive, I'm responsible for taking you there."

Xu Xin and Xu Ying looked at each other, and then entered them one after another.

The interior space is really small, so I can only sit inside like a car and can't stand up.

"Close the hatch door and take off."

The propeller rotated rapidly and hung up in the air with the entire fuselage.

But surprisingly, there were three large propellers spinning at such a speed, but there was basically no sound.

Silent propeller?

"The voice is so small." Xu Xin sighed.

This technology is really hard to understand. The noise is probably not as big as the computer fan...

"Of course, it must be small. The purpose of this flight shuttle itself is to explore the underground world. If the sound is too loud, it will cover up some key sounds and attract large numbers of monsters, so it must be hidden."

Not bad, at least it won't be discovered by alien invaders because of their sound.

The sense of security has been greatly improved.

The shuttle flew into the air and rose to a position nearly a hundred meters above the ground.

"Sit down."

This area is quite flat, so the flight shuttle starts to accelerate horizontally.

After a strong back-pushing feeling, the speed began to stabilize.
