"Over a thousand kilometers, two hours?"
Xu Xin repeated it.
Xu Ying also looked at the man: "Five hundred kilometers per hour, this speed is not slow at all in the underground world. Have you...prepared the vehicle for us to ride?"
"certainly."
The man nodded.
"Since I'm responsible for providing you with a location, I naturally have to see you through to the end. In the underground world directly beneath this World Tree, we have placed a flying shuttle. You can take this flying shuttle to travel through the underground world."

Flying shuttle...
Xu Xin thought of the army of flying vehicles that were like a swarm of flying insects fifty or sixty kilometers away when he left the World Tree.
Could it be that kind of aircraft?
"What you provided is the aircraft of the alien invaders, right?" Shi Wanyun asked, "Is it true that using this aircraft will not be detected by the invaders?"
Can the military equipment of alien invaders really be used at will?
"Don't worry about that. This aircraft is used by our organization." The man explained.
"This aircraft was actually scrapped due to a malfunction a hundred years ago. We didn't scrap it, but instead collected it and modified it. The positioning device had long been removed, and many anti-positioning devices were installed on it. It may not be able to escape the tracking of alien invaders above ground, but it is completely safe in this underground world. As long as you don't get too close to their base, you'll be fine.
Members of our organization have used this method to travel between underground worlds and have communicated for hundreds of years, and have never been discovered by "maintainers of order" or alien invaders, so you can rest assured."
So that's how it is.
Xu Xin nodded.
The "organization" that the man mentioned is the "rebels" of this time and space. Because they are too weak, they have only been able to communicate secretly underground for thousands of years.
They didn't even dare to use communications, because all long-distance communications required the use of satellites from alien invaders, which were likely to be intercepted and eavesdropped by the "maintainers of order." Therefore, over the past thousand years, they had developed the ability to come and go without a trace in the underground world.
"You guys are really amazing..." Xu Ying expressed surprise at the methods used by the rebels in this world, and then asked, "Why didn't you tell us about this the last time we spoke?"
"The last time I spoke to you, I didn't completely trust you," the man said. "Didn't you also not completely trust me?"
That's true.
The conversation between the two sides was not pleasant at the time, and basically no consensus was reached at the beginning.
Fortunately, Xu Xin and his team later found a monster and let it act as a bridge between the two sides.
When the man saw that the monster could speak human language and communicate stably, he couldn't believe what he saw.
Later, the two sides exchanged some information and finally reached an agreement.
"Although I still can't believe you'll succeed, the alien invaders have indeed arrived, and everything is just as you described," the man said. "That's why we've decided to spare no effort in helping you. Of course, as you said before, you must not expose us. We also need to leave ourselves a way out."
As long as they are not exposed, they can still survive even if Xu Xin and his team fail.
"Don't worry, exposing you won't do us any good." Xu Xin waved his hand. "In that case, let's not waste any more time. Let's set off now. Shi Wanyun, you..."
Shi Wanyun said softly: "I will do what I should do. You must be careful."
Shi Wanyun's abilities have nothing to do with combat, so she naturally won't go with Xu Xin and the others.
But, Shi Wanyun is the owner of this world tree.
And this place is surrounded by the vast ocean. For alien invaders, this is definitely a place they don't want to come to.
Therefore, this is also their retreat.
If Xu Xin and his team failed, there would be no point for Ji Chaoyang and his team to continue persevering.
Then they can move directly from the inside of the World Tree to the other World Tree.
They are not going to do this with all their might, they have to leave a way out for everything.
The last time Xu Xin came here, he had already set up the coordinates here and connected it to the interior of the World Tree.
Although the inside and outside of the World Tree have poor compatibility due to the difference in time flow rate, making communication and transmission impossible, as long as the time flow rate inside and outside is adjusted to be consistent, transmission and communication can be achieved.
In other words, once Xu Xin and his team failed, or Ji Chaoyang and his team could no longer hold on, they would directly adjust the flow rate difference and then transfer all the people in the World Tree to this island.
At this time, Shi Wanyun, the owner of the world tree, is needed to receive the personnel.
Of course, if this situation really happens, it does not mean that Xu Xin and the others will abandon the World Tree over there with a huge time difference.
Even if the World Tree over there cannot be defended, it will only be injected with toxins by the alien invaders and cause it to wither completely.
But the time of withering is limited. It won’t be long before the World Tree will grow back again because of its strong root system.
However, the alien invaders do not have access to the World Tree, so they cannot use it.
In other words, when the storm is over, Xu Xin and the others can still find a time to return to the World Tree.
