For the next period of time, it seemed as if nothing had happened in the World Tree.
Everything is going according to plan.
The monster's existence was not discovered by those inside the World Tree, and its arrival did not attract anyone's attention.
And it left after discussing with Wen Guixin.
Of course, it did not leave the World Tree.
Without Xu Xin and others' permission, it could not leave, and it came here to seek cooperation, so it did not need to leave.
But it did not stay in the current densely populated areas, because its appearance is inherently unacceptable to humans. Even if the survivors are well-informed and may be able to accept it, those humans in the underground world may not be able to accept it.
Of course, the most important point is that although it is half human and half monster, because it grew up with alien invaders, its aesthetic is more inclined towards the monster side.
Therefore, it does not want to live among a group of humans at all. This is more terrible than hell for it.
So, it planted a tree house at the very edge of the world inside the World Tree and lived there temporarily.
Although it is a bit far from here, it has the ability of space teleportation, so distance is not a problem for it.
"Alas, although my life is basically the same as before, I always feel like I'm no longer in the mood to relax."
Li Wenxi sat on the sofa, leaning one shoulder on Xu Xin, and sighed.
Now, five days have passed since the monster arrived at the World Tree.
It is five days inside the World Tree.
Just over an hour passed outside the World Tree.
The petrified creatures are now very close to the World Tree, and it will probably reach the edge of Crystal City in less than fifteen minutes.
Of course, fifteen minutes in the outside world is a full day inside the World Tree, so they are not in a hurry.
Now that we know those petrified creatures are not enemies, there is really no need to rush.
"Do you think we are really going to do that?" Li Wenxi asked softly, "Using the World Tree as bait to attract the alien invaders' army... Isn't that too dangerous?"
Danger is definitely dangerous.
Moreover, this is basically equivalent to betting the lives of the people living in the World Tree.
"We still have plenty of time to consider it." Xu Xin held her in his arms, "This is just one of the proposals."
However, this is the only proposal that can be seen so far that has a chance of successfully driving alien invaders out of the earth.
The World Tree is the only thing that qualifies as bait, and if the alien invaders' army is fully stationed, it will be basically impossible for them to sneak into the important areas.
"Well... our life is pretty good now, so... why don't we just continue like this..."
Li Wenxi's voice became smaller and smaller. She felt that what she said was a bit shameless, but this was exactly what she thought now.
"This... is also an option." Xu Xin said with some melancholy.
During these three days, the explorers discussed this matter more than once, but basically no one could make a good decision.
At the same time, he also discussed it with Ji Chaoyang alone.
The two people have basically reached a consensus on their ideas and opinions.
That is…
In short, develop military power madly first.
Just develop your strength first.
The others can be put aside for now, and the focus can be on replenishing the military forces.
Fully arm the World Tree, and fully arm the people in the World Tree as well.
To the extent that every citizen can become a soldier.
Then they will use the most powerful weapon in their hands: nuclear weapons, and expand their numbers to the maximum extent!
Because they have the space to store data, even if they have a lot of nuclear weapons, they don’t need to spend a lot of energy to maintain and preserve them.
So no matter how many you make, safety is guaranteed.
At the same time, Ma Hongwei and Zeng Tao's focus in weapons manufacturing has completely shifted to missiles, to ensure that their nuclear weapons can be launched first.
In short, it is a mad development of military force.
As for what happens next, well...
Let's take it one step at a time.
For the time being, they have no plans to take the initiative and expose their strength.
Because they don't know how strong they have to be to resist the attack of alien invaders.
They both chose the safest approach at the moment: waiting for the alien invaders to arrive.
If the other party comes to their door, they will fight back and implement the previous plan.
If they don't come to them, they will try their best to develop their own military force, but no matter how strong the military force is, it will not be strong enough.
As for the alien invaders...
The monsters have told them that the alien invaders have entered a period of stagnation in technological development. In simple terms, they can no longer become stronger.
Therefore, the longer the time goes, the stronger they become, the more beneficial it is for them!
Maybe the alien invaders will become more chaotic inside.
"I just can't calm down..." Li Wenxi lay on his legs.
"Yingying hasn't come back yet?" Xu Xin changed the subject.
"Well, no, it's only been over an hour outside, how could it be that fast?"
After negotiating with the monster, Xu Ying ignored Xu Xin's obstruction and went out of the World Tree to the underground world.
She wanted to add some population to the World Tree.
Because the thousand people inside the World Tree now are too few to fight against alien invaders.
They need more people and more labor to develop faster!
However, Xu Xin is very worried about Xu Ying's current condition.
He already knew that when Xu Ying entered and exited the World Tree, the difference in the speed of time flowing inside and outside would cause disorder in her own space and time, aggravating her symptoms.
"Yingying will be fine." Li Wenxi saw Xu Xin's worried expression again and comforted her, "Yingying asked me not to worry before she left. She said she didn't want to die now. She wanted to at least witness the alien invaders being driven away, so she wouldn't joke with her life."
Xu Xin sighed: "I know, I also know that she won't commit suicide, but I'm afraid that she may not be sure of her own situation, or something special may happen..."
"Don't worry, Yingying has lived for more than 300 years. She can handle these things better than we can."
“That’s right.”
…
After resting for a while in the villa where only two people were, Xu Xin went out.
It was now daytime inside the World Tree and the sky was still very bright, but there were few people on the streets.
In order for everyone to produce with the highest efficiency and for the sake of everyone's health, a timetable has been established within the World Tree.
And now, according to their time, it is already midnight and everyone has gone to bed.
But Xu Xin knew that one person couldn't rest.
"Brother Xin, you are here."
When Xu Xin entered the tree house, he saw Ma Hongwei studying something with his head down.
There were metal parts and equipment all over the floor, and an unpleasant smell of fuel.
The metal parts all over the floor made Xu Xin feel relaxed.
The changes in Ma Hongwei's laboratory truly symbolize their current development speed.
This was Xu Xin’s previous tree house. Due to its large area, the first and second floors were specially connected.
Ma Hongwei does not live in any house at present, but lives in this tree house, where he basically spends all day and night.
Because of the new technology, Ma Hongwei has become almost obsessed with researching weapons.
He has been in this state for a long time, starting after Xu Ying came. According to the time in the World Tree, it has been two months.
Xu Xin originally thought that this state was just a momentary excitement, but he didn't expect it to last so long.
However, he was happy to see this situation.
"How is it going? Is there any progress in the research?" Xu Xin walked to Ma Hongwei.
"It's almost done, just in accordance with your requirements, Brother Xin." Ma Hongwei pointed to a two-person-high facility nearby.
A... missile launcher.
"So small?" Xu Xin was a little surprised.
There was a missile mounted on the launch device, and the length of the missile was just over one meter.
"It's just a current prototype. We'll make a large one in the future. As for the large-scale production, it will be left to Zeng Tao." Ma Hongwei explained.
Zeng Tao's ability is to make large-scale weapons.
“That’s right.”
Xu Xin nodded.
Zeng Tao is now very skilled in weapons research and development. Using her abilities, she can easily carry out large-scale research on the weapons developed by Ma Hongwei.
"According to your requirements, this launcher can reach a maximum speed of about Mach 50 in the atmosphere when used with our missiles. However, since the main fuel is used for explosive propulsion, the missile's range is greatly reduced. If the target location exceeds 100 kilometers, the accuracy will be greatly reduced."
In other words, this is a missile that greatly enhances its flight speed at the expense of its range.
This is also the weapon that the World Tree needs most at present.
No matter how far the range is, it will be of no use on this huge planet.
Because their missiles cannot cross half the planet to attack alien invaders. Even if they have the range, it probably won't have any effect if the other side has an anti-missile system.
Therefore, their focus is on developing "defensive weapons."
They need to ensure the safety of the area around the World Tree, and this missile, which has a short range but extremely fast speed and is almost impossible to counter, is the weapon they need most at the moment.
A strike that cannot be countered against the area surrounding the World Tree.
Mach 50, which is 50 times the speed of sound, is already a very impressive speed.
You know, thousands of years ago, missiles that could exceed Mach 5 speeds in the atmosphere were called hypersonic missiles.
Mach 50, that's really exaggerated.
About 17 kilometers per second.
Even if a missile is launched outside the World Tree, if people inside the World Tree observe it with a time flow rate difference of a hundred times, it will still be at a speed of half Mach.
In other words, if you launch a missile inside the World Tree, and look outside the World Tree where time has almost stopped, you can still see that the missile is fired at a speed of more than 170 meters per second, or more than 600 kilometers per hour.
Even if it is slowed down a hundred times, it is still close to the speed of a civil airliner.
Xu Xin felt that a missile of this speed should be impossible to intercept.
It is completely sufficient for defense.
If you put a nuclear inside...
"In this way, I can rest assured for the time being."
Xu Xin felt that this was the first time he felt somewhat relaxed since the monster came.
"I'll try to finish it within two days, and then I can hand it over to Zeng Tao to enlarge it."
Xu Xin nodded.
Then he touched his chin and looked at the tiny little missile.
This pocket-sized device seems like it can be carried around.
Although small missiles can carry much less ammunition, their power cannot be underestimated if they are nuclear.
If one day they really want to sneak to the other side of the earth to destroy the scarlet crystal, this kind of missile may be of great help!
"You haven't rested today, go to bed early, and don't keep using the purple oranges. It's not good for your health." Xu Xin stood up.
Oranges above blue level are used to refresh the mind by overdrawing life. They have already told this to all the survivors in the World Tree. Currently, these people basically no longer eat blue-level fruits.
However, fruits of purple grade or above are much less harmful to lifespan. In addition, the resources in the World Tree are very abundant now, so purple grade fruits have become everyone's first choice.
But you can't eat it often. Although it may grant some powerful abilities at the moment, it will still affect your lifespan.
"Don't worry, Brother Xin. I've been injected with genetic drugs, so I have a very long life. Making weapons is more important."
Ma Hongwei refused to listen and continued to devote himself to his research.
Xu Xin shook his head helplessly, stopped bothering him, and came down from the tree house.
"ah-"
In the distance, the pterosaur Huihui was gliding towards this side at an extremely fast speed.
A few seconds later, it landed next to Xu Xin and rubbed its big head against Xu Xin.
"Bing!"
Coco, who was lying on Huihui's head, jumped down and landed on Xu Xin's shoulder.
"Have you had enough fun?" Xu Xin rubbed Coco's little head.
"Bing!"
This little guy often comes out to play with Huihui recently.
The injuries Huihui suffered last time had long since fully recovered, leaving no traces.
"I'm going back now. I'll see you next time."
"ah!"
Xu Xin brought Coco to a coordinate.
He reached out and touched the coordinates, a purple-black vortex condensed, and a portal appeared.
Xu Xin stepped into it.
After the world spun around, he appeared at the edge of the entire world inside the World Tree.
The endless high wooden wall represents the end of this world.
Here, there are three tree houses, each of which is a three-story tree house, and the area of a single floor reaches four to five hundred square meters.
These are all very large tree houses.
"Xu Xin, is there something wrong?"
The window of one of the tree houses is open.
The monster's ugly head full of eyes appeared in the window frame.
Because there was no one else around at this time, the monster did not open only the two eyes on its face as before, but opened all its eyes.
The eyes did not blink simultaneously, but blinked one by one from left to right. The eyes on the upper body of the monster exposed from the window surged like waves.
This made Xu Xin feel a little physically uncomfortable, and the corners of his eyes twitched slightly.
“Hmm…” Coco simply shrank her head and closed her eyes.
"I heard your experiment is about to succeed."
Xu Xin looked at the monster and said.
"What? Do you want to stop my experiment?" The monster's strange voice sank slightly.
"Of course not. I'm just curious about how far your experiments have progressed. Are you really going to create a race?"
The monster lives in the most marginal area, and an important point is that it wants to continue its experiments here.
This was actually the condition that Xu Xin and Xu Ying agreed to.
In the World Tree where time flows a hundred times faster, it is given an area to allow it to continue its experiments. In exchange, it cannot attack the humans in the World Tree.
“…it is so difficult to create a race.”
The monster disappeared in the window frame, and then a purple-black vortex instantly condensed in front of Xu Xin, and the monster walked out of it.
He appeared in front of Xu Xin almost instantly.
"嘤!" Coco was startled and hung directly behind Xu Xin, with only half of her head exposed to look at the monster.
The monster ignored Coco and continued, "But, although it is difficult, I have taken the first step. I awakened one of them."
"It has a clear consciousness, but unfortunately... like me, it does not have the ability to reproduce."
Xu Xin was immediately shocked: "Someone has survived?"
He looked at the three tree houses: "In the tree house?"
"Yes, he has gone to bed." The monster's mouth split open, as if smiling, "My first fellow is in good condition."
… and it actually worked!
"Amazing." Xu Xin praised sincerely, and then said, "I won't watch it. I came here to tell you that the petrified creatures are coming soon. What do you want to do?"
It is it that controls the petrified creatures.
"I will hand over the command of the petrified creatures to you." The monster said immediately, "This is my first gift to you."
Xu Xin smiled slightly.
It seems there is no need to waste further words.
