In the dark underground world, a flying shuttle is moving quickly.
This flying shuttle is almost silent, and even when flying at a speed of over 500 kilometers per hour, it does not produce any noticeable noise.
The underground world is huge, like an abyss. In the vast darkness, this aircraft is like a firefly, illuminating a small area nearby.
But it's only a small part.
"Hmm..." Keke was tired of the boring scenery outside the window. Her little body had curled up in Xu Xin's arms. She yawned and began to feel sleepy.
"By the way, if we keep the lights on, won't we be easily discovered?" Xu Xin asked the man.
"You don't have to worry about that around here for now, but after another 200 kilometers, you'll need to turn off the searchlight," the man replied.
"Then in the darkness..."
"Don't worry, the flying shuttle can scan the surrounding one kilometer terrain clearly. Although the travel speed will be reduced, it is still 400 kilometers per hour."
"That's good." Xu Xin nodded and looked out the window again.
"By the way, I haven't asked your name yet." Xu Xin suddenly said.
"My name..." The man paused, then smiled bitterly, "My name? I almost forgot it... My last name is Yang. You can call me Old Yang. They all call me that."
"Lao Yang, if we succeed, what do you want to do?"
"Success..." Lao Yang's voice became slightly melancholy, "Haha... If you really succeed, then maybe I... Sorry, I don't have any ideas for the time being. I have never thought about this. These things are out of reach for me."
"Have you really never thought about what will happen after you gain freedom?"
"Get freedom?" Old Yang shook his head. "For so many years, what we have been thinking about is how to let more people survive. How can we talk about freedom when survival is difficult?"
This sentence is really sad.
"Before the survivors arrived, we had been trying to avoid being studied and killed by the alien invaders. You know, watching the number of our companions decrease day by day, not knowing when we would be selected, subjected to inhuman treatment and die on the test bench... We have been living in this fear for nearly a thousand years."
Lao Yang's voice was low, and the tone was like someone who had just woken up from a horrible nightmare and was telling people about his dream experience in a cold sweat.
No, this is not a nightmare, this is real.
Xu Xin was silent.
“Hmm…” Coco raised her little head slightly.
"Later, survivors appeared." Lao Yang's voice became slightly softer. "We have new companions. After that, we can be said to have rekindled hope. What we need to do now is to let more people survive..."
He turned his head to look at Xu Xin: "I once had someone kill you. I apologize to you. You were there at that time, right? What I said at that time was not false at all. If you and your world tree continue to exist, the other survivors in this batch, and even us... may suffer."
"… Then why are you helping us now?"
"Because... there is a 'god' on your side, or... should we call it a 'demigod'?"
Demigod...
This name is really a bit childish.
"That's the survivor plan it proposed," said Lao Yang. "It sends people who should have died a thousand years ago to the future, and gives them a chance to survive."
"... It just wants to complete its plan." Xu Xin said.
"No matter what it wants to accomplish, for us, it has indeed saved many lives and given hope to those of us who are almost in despair. After knowing that it also has half human blood, we see hope again."
So I decided to help them...
Xu Xin discovered that the other party's attention was actually completely on the monster.
The other party's hope and almost non-existent confidence were all given by the monster.
He didn't believe Xu Xin and the others, but he felt that since there were monsters around, this plan had little hope.
And Xu Xin and the others don't seem to be the focus.
Well, Xu Xin could still understand him.
Having been enslaved by alien invaders for thousands of years, in their hearts, it is impossible for humans to defeat the alien invaders.
In their minds, only alien invaders can defeat alien invaders.
Because of this deep-rooted concept, the first negotiation between Xu Xin and Lao Yang was so unpleasant and they hardly reached any consensus.
But then the monster appeared and everything went smoothly.
Here's why.
But it doesn't matter.
As long as you can help them, no matter what the reason is.
The aircraft continued to sail in the endless darkness.
…
On the other side, the World Tree.
After Ji Chaoyang and his men launched the attack, the army of alien invaders suffered the first wave of nuclear strikes.
The mushroom clouds rising into the sky are very spectacular.
The legions of alien invaders also responded immediately.
Outside the Mushroom Cloud, those aircraft that were not affected by the nuclear explosion no longer moved forward at a snail's pace, but instead exploded at super high speeds one by one, rushing towards the World Tree!
This speed is really fast. It is estimated that each aircraft can reach a speed of about 2,000 kilometers per hour!
This is not a fighter jet, but a flying vehicle that can fly slowly and even hover!
This aircraft can reach a speed of two thousand kilometers per hour, which is truly amazing.
I didn't expect that something with this structure could reach such a speed!
And this is probably not the maximum speed of this aircraft!
However, two thousand kilometers per hour is still too slow when viewed from inside the World Tree.
With the blessing of the World Tree's time flow rate being a hundred times faster, the people inside the World Tree looked at the speed of these aircraft as if they were looking at a group of cars occupying the road moving forward at a snail's pace of twenty kilometers per hour.
Only in traffic jams would the speed be this slow.
On the other hand, the World Tree has missiles that travel at fifty times the speed of sound.
Thus, the war escalated again!
"emission!"
At Ji Chaoyang's command, the second wave of attack began!
"Bang!"
Missiles poured out from the World Tree in all directions like raindrops. Every missile produced a deafening sonic boom when launched. For a moment, the entire World Tree began to tremble slightly!
Not to mention the giant beasts under the World Tree, they were all shocked to the point of feeling dizzy!
A mushroom cloud rose up again in the distance. This time, the magnitude of the mushroom cloud was incomparable to the previous one. Before, only dozens of rounds were test-fired, but this time, hundreds of rounds were fired outwards at the same time and arrived at the same time!
The world fell into white again.
The white light faded away, and a terrifying mushroom cloud gradually took shape and was born in the explosion, slowly rising into the air.
"No matter how strong they are, they can't withstand the power of a nuclear bomb." Qin Yunlong said as he looked at the mushroom cloud outside the World Tree that was slowly taking shape at a speed a hundred times slower.
"Don't be too optimistic." Ji Chaoyang said in a deep voice, "The power of a nuclear bomb is not as great as you think."
The energy released by any flare on the sun is equivalent to that of billions of million-ton nuclear bombs.
The flying vehicles created by the race that can travel in the starry sky will probably not be defeated so easily.
Not to mention that the nuclear bombs they are launching now have a relatively small equivalent. After all, if the equivalent is too large, at such a close distance, it may directly affect their survival.
The mushroom cloud was still slowly rising into the sky.
At this moment, a missile suddenly pushed away the smoke of Moguyun and rushed out at a high speed!
Flying towards the World Tree!
“This is so fast!”
Suddenly, everyone who was operating external weapons in the World Tree was stunned.
Outside, time flows a hundred times slower!
Even if it was a hundred times slower, the speed of the missile was approaching extremely fast!
In less than ten seconds, the World Tree will be hit!
Ji Chaoyang and Tong Kong shrank suddenly and clenched their fists.
The missile is coming in an instant!
Just when it was only a few hundred meters away from the World Tree, suddenly, several lasers shot out from various parts of the World Tree's crown!
And their target is this missile!
In just a blink of an eye, the missile suddenly exploded in the air and broke into countless pieces.
Under the gaze of everyone in the World Tree, the fragments slowly splashed in all directions.
Ji Chaoyang let out a breath.
He even held his breath just now.
At the same time, dozens of missiles like the ones just now flew out from the mushroom cloud again, all shooting towards the World Tree!
Fortunately, the laser defense system on the World Tree has been deployed very densely during this period of time.
Almost every missile is accompanied by dozens of lasers.
The end result was that these missiles collectively exploded one kilometer away from the crown of the World Tree, and the fragments scattered in all directions.
After this wave of attacks, the opponent temporarily stopped moving.
The power of laser defense made the group of people who were nervously observing the outside world excited!
At this moment, their mood was like a roller coaster, with ups and downs!
“So strong!”
"Invincible! Our laser anti-missile system is truly invincible!"
"Oh my god, the speed of that missile just now must be at least twenty times the speed of sound!"
"The alien invaders are still strong..."
"Huh? We all have missiles that travel 50 times the speed of sound. Isn't it normal for alien invaders to have 20 times that?"
"What the hell are you talking about? That's a missile on an aircraft! There's no need for a super-powerful launch device. The missiles on the aircraft can reach more than twenty times the speed of sound!"
"Yes, if this was our plane, after firing the missile, it would be thrown directly to the ground and destroyed on the spot!"
"Fuck, now that you put it that way, it seems to be true!"
"Tsk, tsk, tsk, so powerful. However, no matter how powerful it is, it can't be stronger than our hundred times time flow speed and automatic laser anti-missile system."
"Yes, no matter how many times it is multiplied, in front of the speed of light, we are all grandchildren among grandchildren!"
"It's a pity that the effective range of our laser is too short, only one kilometer."
"Hey, it's enough for me."
"That's why I say that because they're not enough! You can only laugh like that because these missiles are so weak. If this were a nuclear bomb and it exploded less than a kilometer away from us, guess what would happen to us!"
"this… "
Ji Chaoyang and others had already frowned and started thinking about this problem.
"From the current perspective, the power of the missile they just launched... seems to be very small." Qi Xuefei observed the fragments that were still slowly flying around outside and said, "It seems a little... too small."
"I feel it's too small too." Qin Yunlong said, "The explosion power is probably not even as strong as a grenade. It should have been destroyed before the explosion, right?"
"... Did you notice that when those missiles exploded, some of the liquid seemed to splash out, and some was evaporated." Ji Chaoyang suddenly said while observing the outside.
"Ah? I didn't see it." Qin Yunlong shook his head. "It was one kilometer away, so I couldn't see it clearly."
"I saw it too. I thought it was the coolant inside, or some other liquid." Qi Xuefei said.
"No... maybe it should be..."
Ji Chaoyang held his chin, thought for two seconds and said: "Maybe it should be... the toxin that can make the world tree wither!"
Yes.
The liquid just now... was green.
It is green in color, just like the tube of toxin that Shi Wanyun got.
Moreover, the color of the liquid this time seems to be darker, which confirms what the monster said: "It can only take effect on the World Tree after being concentrated."
"If that's the case, then... we'll have to rely entirely on our anti-missile system." Qi Xuefei's expression was a little serious at this time.
Don't let any missile hit the World Tree!
Otherwise, the World Tree would probably begin to wither under the influence of these missiles!
Fortunately, it seems that their laser defense system is still very effective.
At least dozens of missiles were fired at the same time, but they were all easily shot down by the anti-missile system. There was even an oversaturation situation, that is, one missile was countered by dozens of lasers at the same time.
In other words, even if the local missile density is ten times higher, it will not be a problem.
"It's okay, it's okay." Qin Yunlong said to himself, comforting himself, "Our anti-missile system is very strong. Our strike capability is also very strong. Attack is the best defense!"
“…Hold on! We must buy time for Xu Xin and the others!” Ji Chaoyang said in a deep voice.
"I don't know what's going on over there..."
At this moment, several aircraft emerged from the edge of the mushroom cloud.
Under their gaze, several missiles were fired again from under the aircraft and flew towards the direction of the World Tree!
The war continued.
This continued for a long time.
…
An hour has passed since Xu Xin left.
And four days have passed in the World Tree.
During these four days, the explorers did not sleep a wink.
Of course, with the effects of high-level fruits, they did not feel sleepy. Instead, they were always alert and paying attention to the situation outside the World Tree.
At this time, outside the World Tree and within a ten-kilometer radius around the World Tree, the scene was already devastated.
It was full of potholes and lifeless, like the end of the world.
Countless aircraft have surrounded the World Tree, but they are still about ten kilometers away from the World Tree.
After all, the firepower of the World Tree is very strong, and they dare not rush up at will.
In the previous battle, they also lost a considerable number of aircraft.
And most of their army of mutant creatures were also killed.
"Why do I feel like they are easier to deal with than I thought?"
"Yeah, by the way, it's been an hour outside, right?"
"I thought they were so strong."
"Haha, it's not that they are weak, it's that we are too strong!"
"Why are you so optimistic? They are about to attack within a ten-kilometer range!"
"Yes, within a ten-kilometer radius, we cannot use nuclear bombs at will! Otherwise, it will affect us too!"
"What are you afraid of? The World Tree is so strong, it will protect us!"
"But… "
"Wait... Holy shit! What is that?!"
"Ah? Eh? Huh?"
"Oh my god! What the hell is that?!"
Everyone exclaimed.
Ji Chaoyang and others also changed their expressions in shock.
"That... what is that thing?" Qi Xuefei muttered to herself.
I saw a white mountain of flesh slowly rising at the location of the lake only two or three kilometers away from the World Tree!
The mountain grew taller and taller, ten meters... twenty meters... thirty meters...
Ji Chaoyang's expression changed: "Wait... Could this be..."
His eyes shrank.
The disappeared insect queen in the underground world? !
