Starry Sky Train, I opened a small shop on the train

Chapter 575, The Tree of Imaginary Numbers Descends
Ye Yun led the group of children back to the train.

As soon as I got back, I saw Xiao Hei, who had been waiting for me for a long time.

Xiao Hei saw Ye Yun transform into human form.

"Ye Yun, I've already informed Sister Fukalos, and I want to go back now."

Ye Yun nodded upon hearing this and asked the system to help him send Xiao Hei back to his original world.

As soon as Xiao Hei left, Puni's voice rang in Ye Yun's mind.

"Boss, there's a guy named Tree who wants to talk to you about something."

Ye Yun frowned upon hearing this.

"Tree? Who is he?"

Puni said.

"Yes, he seems to be the owner of this universe. He just contacted me and said he has something he wants to talk to you about."

Ye Yun pondered upon hearing this.

The owner of the Honkai Impact 3rd world? A tree?
Could this be the tree of imaginary numbers?

“Puni, ask him if it is the Tree of Imaginary Numbers.”

After a moment of silence, Puni replied quickly.

"Yes, boss, he said he is the Imaginary Tree that many creatures talk about. Do you know him, boss?"

Ye Yun shook his head.

"I don't know Him, but I've heard of Him. Where is He?"

Puni said.

"The entity I observed is not in this universe, but outside of it."

However, He had an alter ego beside me.

This guy is no ordinary person. Boss, how about I act as the messenger?
Although I can't do anything to Him, He can't do anything to me either. Just wait two months, and you'll see how I slap him across the face then.

Ye Yun thought for a moment and was about to agree to Puni's proposal.

The system's voice suddenly sounded in his mind.

[Information: Please invite this world ruler to the store. The system has a collaboration to discuss with him.]

Rest assured, host, this guy won't cause any trouble in this shop.

Ye Yun was somewhat surprised upon hearing this.

I never expected the system to proactively invite the Imaginary Tree to the store and even discuss cooperation? That's interesting.

Immediately, Ye Yun contacted Puni in his mind.

“Puni, bring Him onto the train.”

Puni was very surprised.

"Boss, are we really going to take this guy to the store? If he starts acting violently, I won't be able to protect everyone on the train."

Puni's strength is currently slightly weaker than the Imaginary Tree's clone. Puni can withstand the Imaginary Tree's attack in one strike, but it is difficult for him to protect others from the Imaginary Tree's attack.

Ye Yun said.

"Don't worry, he can't cause any trouble in the store."

Upon hearing this, Puni said nothing more.

“I understand, boss. I’ll take Him back right away.”

Then, Puni's voice disappeared, and Ye Yun looked at the group of little ones playing nearby, including Keli, Qiqi, and Kanna.

"Keli, Qiqi, you guys go back to Rose Castle for a bit. Your brother has a very important guest coming over soon."

Keli, Qiqi, Zaoyou, and the other little ones all agreed in unison.

Half an hour later, inside Ye Yun's shop.

A woman with waist-length white hair, who exuded a sense of holiness, sat with Ye Yun in a teahouse.

The woman is an incarnation of the Tree of Imaginary Numbers.

Ye Yun poured a cup of tea for the Tree of Imaginary Numbers and asked slowly.

"What do you call it?"

The Tree of Imaginary Numbers picked up its teacup and took a small sip.

Just call me Tree.

Ye Yun nodded.

"Hello, Tree. I don't need to introduce myself, do I? You've already come all this way."

The tree nodded slowly. "Yes, I've come to inquire about something. Where did you send the spirit cat I invited to this world?"

Upon hearing this, Ye Yun...

"It went back to where it came from. What? Is it very important to you?"

The tree nodded in agreement.

"Its existence is very important; it is related to the upgrading of this world."

Ye Yun became interested upon hearing this.

Upgrade? That's interesting.

"Upgraded? Is Little Black that important?"

Shu picked up the teacup, his eyes revealing no emotion.

"What's important isn't the thing itself, but the power system within it."

Among the myriad realms, each realm is also divided into different levels.

The strongest are naturally the fantasy and xianxia (fantasy/martial arts) worlds.

Secondly, there are worlds with supernatural power systems and worlds with advanced technological civilizations.

Below that are some ordinary parts of the world.

The spirit cat contained a power system called the Mystic World.

Although it's weak, it's still a power within the fantasy system.

Once it develops a sense of belonging to this world, its internal power system will be integrated into the world of Honkai Impact 3rd.

With just a little guidance, I can expand this power system, thereby driving the world's ascension.

Ye Yun finally understood; it turned out that what the tree was after was the power system within Xiao Hei's body.

No wonder this guy came looking for me; it turns out that sending Xiao Hei back affected her plans.

"I see. Then you don't need to worry. Little Black brought a portal with it before it went back. It can come to the Collapse Iron World at any time through the portal."

Upon hearing this, the tree nodded slightly.

"Well, I'd like to ask you for a favor: help me strengthen that spirit cat's sense of belonging to the Honkai Impact 3rd world."

In return, I can give you 100 million Le Xingqiong.

Upon hearing this, Ye Yun...

"Strengthen Xiao Hei's sense of belonging? That's easy. He really likes Fukaros and Frynn in Teyvat right now, so we can start with them."

Upon hearing this, Shu casually waved his hand, and the entire shop instantly became sparkling, with the ground covered in starlight.

Ye Yun was amazed.

My goodness! No wonder he's the Lord of the World; he presents Xingqiong as if it's free.

Seeing Ye Yun's shock, the tree said.

"I cannot create this star either; it is formed from people's wishes."

Only with strong enough willpower can a star be formed.

That's right, everyone watching, you're not sincere enough, that's why you got the wrong cards in your gacha pulls, hehe~ I haven't gotten a wrong card in 26 consecutive pulls, hehe~
Upon hearing this, Ye Yun nodded to indicate that he understood.

"By the way, there's something else I wanted to ask you. What's the deal with Xiao Hei's spatial abilities? From what I know of it, it probably doesn't know it has this skill yet."

"The tree said."

"Yes, I did it. I made it have a very realistic dream."

Upon hearing this, Ye Yun realized that it made sense.

Luo Xiaohei's timeline is clearly still in the forest. The forest was flattened by humans, so he went to the city to wander, then met Fengxi, and then Wuxian.

The forest where Little Black lives.

Xiao Hei returned here, and as soon as he came back, he called his clone, Meow, over.

He didn't bring Meow with him when he went to the Honkai Impact 3rd world before.

Or rather, there wasn't time to bring them along; Xiao Hei himself was forcibly dragged over.

Little Black caught the meow that was rushing towards him.

"I'm back! I brought back lots of delicious food!"

Xiao Hei transformed into human form and took out a bunch of snacks from the storage ring on his hand, placing them on the ground.

Xiao Hei picked up a bag of bear-shaped biscuits.

Let's eat together!
