To be cautious, Fang Zheng did not go to the planet immediately this time. In the end, he chose to send nanomachines for reconnaissance.

The results of the investigation also surprised Fang Zheng and his team.

Although this place looks like a planet on the surface, it is actually different from a real planet. Perhaps because it is the core root of the Imaginary Number Tree, this planet is actually connected to different areas. They are even isolated from each other and do not know each other.

Strictly speaking, this is very similar to the third coordinate point where Fang Zheng was once. Although several worlds have a common core, because the world is broken, each world is also separated from each other... Then again, I don't know how Emilia and the others are doing in the revolution at the third coordinate point, but Fang Zheng is not very worried about the safety of Emilia and Felt. After all, there is the help of Academy City and the assistance of the Empire, plus Kurumi's clone is also there. Although the Tiandao Palace will not intervene in the war personally, if Emilia and the others really can't bear it, it is still no problem to rescue them.

But if Emilia can lose even with the help of Misaka Mikoto and the others... well, that's not likely.

This is not important, let’s get back to the topic.

If that were the case, then there would be nothing strange about it. Basically, each landmass on this planet formed a separate small world, connected to other worlds, just like the branches on a tree trunk extending in all directions.

And then there is the problem… that is…

"It seems that there are quite a few people who think the same as us..."

Fang Zheng silently stared at the scene on the screen and complained without words, while the others were also stunned, not knowing what to say.

That's right. In fact, it's not just Fang Zheng's Blue Fleet that can strike the root and want to destroy the core of the Imaginary Number Tree. Those plate worlds have also encountered invasions from the core armies of various world bubbles.

Basically, the descriptions in these plate worlds are consistent. People originally lived a peaceful life, and then suddenly one day, a monster named "XXXX" appeared and attacked them, so people took up arms and fought against the monster named "XXX"... No one knows where these monsters come from, or what they want, but they only know that they want to destroy or occupy the planet...

Well, it is true that where there is oppression, there is resistance.

Obviously, apart from the branch of the collapsed world where Fang Zheng was, the world bubbles on other branches were not vegetarians. It was just that each force had different ideas. Some wanted to completely destroy the core area of ​​the Imaginary Number Tree, some wanted to occupy the magpie's nest, and some wanted to obtain the power of the core of the Imaginary Number Tree...

Logically speaking, Fang Zheng should now raise a flag, issue a manifesto, and join the 18 princes to form an anti-Dong Zhuo... No, anti-Imaginary Tree Alliance, then break through Hulao Pass and take Luoyang directly...

However……

"Yuuki-kun, who should we help???"

"Well……"

Facing Xilian Temple Haruna's question, Fang Zheng scratched his head, speechless. The others also looked at each other, quite confused.

The reason is very simple. In order to maintain its own existence, the Imaginary Tree will definitely absorb and harm other world bubbles. However, it is the consciousness of the Imaginary Tree, similar to Alaya and Gaia in the Type-Moon world, and will not directly affect the life on this planet. In other words, the life on this planet basically does not know that such an existence exists, so for them, these mysterious aliens or some messy things that appear inexplicably are invaders who suddenly appear and attack their world inexplicably.

But for those invaders named "XXXX", the tree of imaginary numbers is the root of all evil! You harm other worlds to strengthen yourself, and I have to kill you to protect myself.

This is actually the purpose of Fang Zheng and the others coming here, right?

To put it bluntly, the various plate civilizations on this planet are actually like parasites attached to the tree of imaginary numbers. If the host grows stronger, they will live comfortably. But if the host is attacked, none of them can escape. They will all be blamed by the host.

As the saying goes, when the nest is destroyed, no eggs can remain intact; when the city gate is on fire, the fish in the pond will suffer as well. This is exactly what it means.

The reason why the girls were so confused was very simple, that is, the civilizations in the core area of ​​the Imaginary Tree were basically human civilizations, and those who invaded them were basically non-human civilizations. It can even be said that, as of now, the only human civilization that can make it here is Fang Zheng's Blue Fleet.

Perhaps because the energy conversion efficiency of homogeneous civilizations is higher, the Imaginary Number Tree prioritizes human civilization, giving non-human civilizations time to develop? Just like the heavenly beings in the Collapse World... maybe if they develop further, they will also become a member of the Eighteen Princes' Army?

Damn, why do I feel more and more unhappy when I think about this?

"Let's just blow it up."

Fang Zheng moved his fingers silently, after all, one explosion could solve all problems.

"But... they are humans, right? Shouldn't we help humans???"

Anna spoke with some embarrassment. Whether it was the Valkyrie of the Collapse World or the Manipulator of Sidonia, their mission was to protect humans and fight against foreign invaders. So when they saw this scene, they immediately put themselves on the side of the invaded humans.

"Yes, but our goal is also to destroy the core of the Imaginary Number Tree."

Fang Zheng narrowed his eyes and looked at the planet in front of him.

"Don't forget, if we want to destroy the core of the Imaginary Number Tree, we must destroy this planet. We are not planning to kill the human civilization on this planet, but they will die because we want to destroy this planet."

Fang Zheng felt that his logic was very smooth and there was no problem.

That's right, we don't intend to destroy humanity. We just want to demolish the Earth in order to build a galactic highway.

The plan is right there in Centauri's office. It's been there for a hundred years. Who told you not to go and look at it?

What? You can't leave the solar system?

Oh, I'm really sorry...

Even the expression on Tesla's face was very subtle. After all, they had been fighting against invasion all along, but now they had become the invaders... It took them a while to wrap their heads around it.

The people in the sky do not count. In fact, they have already launched an attack on the earth, but were stopped by Walter. Moreover, they are not like these human civilizations that were affected by the disaster. Instead, they took the initiative to invade other worlds to collect Honkai energy. Therefore, Tesla has no objection to Fang Zheng destroying them.

But now facing these human civilizations...

"Or you can make up your own mind."

Fang Zheng spread his hands and shrugged his shoulders. He was no longer in a hurry. After all, the core area of ​​the Imaginary Number Tree had been found. He could return to his own world by turning it over. So whether these people were going to fight or do something else, it was up to them to decide.

"But it's really strange..."

Cang Xuan narrowed his eyes, stared at the information on the screen, and suddenly spoke.

"What's wrong?"

"Obviously, the Honkai Consciousness can deploy monsters like Honkai Beasts and Kijuu to invade other world bubbles, so why didn't it use this power when its own world core was attacked?"

Although there are many forces attacking the core planet of the Imaginary Tree, if the Imaginary Tree creates a super-large and terrifying cosmic monster like the Volkswagen, then these invaders will be nothing more than small bugs.

"How surprising! I've only seen people inject poison into others, but who would have nothing better to do than inject poison into themselves?"

Fang Zheng shrugged.

"Besides, this is just the periphery after all. It has not harmed the core of the Imaginary Number Tree. For the Imaginary Number Tree, since the outside can block it, it does not need to spend too much energy on defense. As long as the opponent's world bubble is destroyed, these invaders will self-destruct. And the opponent's attack will further strengthen the Imaginary Number Tree's determination to strangle its competitors... Well, it turns out that all tactics are converted."

"I say, is this the time to make sarcastic remarks?"

Tesla rolled his eyes speechlessly and complained, while Fang Zheng shrugged.

"What else? That's all I can say. The decision is up to you."

"…Let's discuss this further."

Next, Tesla, Einstein, Danzhu, Cang Xuan, the Valkyries, as well as the manipulators from Sidonia such as Xing Baixian, as well as Shinjo Akane and Takanari Rikka and others held meeting after meeting to discuss the matter. Fang Zheng did not intervene at all, nor did he allow the girls under his command to express their opinions.

At this point, Kotegawa Yui and the others did not urge Fang Zheng to return to his own world as soon as possible. After all, the way home was just around the corner. Moreover, although they did not help much along the way, they had experienced it all personally. It was like watching a movie, and they also wanted to see the ending, right?

But if you ask them whether they are worried or not...of course they are worried.

"Brother, what decision do you think they will make???"

Looking at Fang Zheng anxiously, Meigan asked softly, and the latter shrugged.

"I don't know about that. They probably feel very conflicted themselves."

Fang Zheng took a sip of red tea, turned the cup and spoke, while Kotegawa Yui stared at him.

"So, what do you think, Yuuki-kun?"

"Me? The purpose of Tiandao Palace is to protect human civilization, so if you ask me, my answer is this. For Tiandao Palace, protecting the existence and reproduction of human civilization is the first priority."

Of course, Americans are not considered human beings.

"That……"

"But this is not our world."

Seeing that Kotegawa Yui wanted to say something else, Fang Zheng decisively interrupted her.

"It's their world, they make their own decisions, and they bear the consequences themselves, that's all I have to say."
