I'm doing abstract animation

Onion Head: "What does this 'copy' mean?"

Flounder: "I promise you, dear friend, that won't affect you much!"

Onion Head: "...And what is this elemental water?"

Flounder: "It can help you master the water element, but of course, if you only have one dose, the effect might not be as strong..."!

How to understand the element of water?

Rukia Kuchiki's eyes widened. She knew that elemental abilities were very difficult to master, and the top-tier Zanpakuto to this day were all elemental...

She clicked "agree" almost without thinking, even selectively forgetting Yuuki's instructions...

In an instant, she felt all the strength drain from her body.

"Rukia, what's wrong, Rukia?!"

A spiky-haired man passing by happened to see this scene and was immediately startled.

"N-nothing, Vice Captain Shiba..."

Rukia Kuchiki gritted her teeth and said she was fine, leaving Kaien Shiba completely bewildered.

What happened to this child?

"It's in hand."

Yuki chuckled, and a blue card appeared in his hand.

The card depicts a girl with onion-shaped haircuts, holding a katana and wearing a black kimono.

"Tsk, but exchanging a Water Elemental for a Blue Card, I'm definitely losing out no matter how you look at it..."

Volume 1: Chapter 45 Yuuki Risa's Trading Partners (Part 2)

Flounder: "Are you there? (づ￣3￣)づ╭～Dear?"

Smiling Butterfly: "Oh my, what is this thing that suddenly appeared in front of me?"

Shinobu Kocho looked at the screen that had suddenly appeared in front of her with some surprise. She had just finished changing the water for the goldfish and was about to go to rest when this transparent screen suddenly appeared in front of her.

These trading subsystems deployed by other worlds will never be activated unless Yuuki Riki engages with them.

Unfortunately, by the time the deal went to Shinobu Kocho, Osamu Yuuki had become incredibly powerful, so he lost interest in contacting her.

That's right, he knew about Shinobu Kocho. Before he transmigrated, the popularity of Demon Slayer had just subsided, and as a fan of shonen manga, he naturally looked into it.

Unfortunately, he didn't have time to watch this anime, which was hailed as a rebirth of the glory of passion, because his wife was pregnant at the time.

All I know is that the main character's name is something like Tanjiro...

He knew about Shinobu Kocho because of those doujinshi from that period... Oops, did I just reveal something...?

"But he's a character from a battle anime, so he must have some strength, right?"

Yuuki nodded. A large portion of his trading list were not combatants, and the combat strength of the other combatants was also ridiculously high. Even Kenshin Himura, who was originally considered an 'ordinary person,' had been forcibly elevated to the level of a transcendent being. It was estimated that even Rukia Kuchiki without any enhancements might not be his match. These two were considered the bottom-tier members of his trading partners, but this was still too overpowered. They were fighting against Blue-level strength right from the start. This would only damage Yukino Yukinoshita's confidence and would not provide any training effect.

Yuki had an idea for their training.

The idea came from a game he played in high school, which involved designing a tower.

In his vision, the tower has ten floors, each with an enemy, and the difficulty increases progressively.

Moreover, they can't just suffer; they also need to be rewarded, because rewards are what motivate them.

You can obtain the character card of each enemy you defeat.

Character cards are different from the cards they obtain in other dimensions. These depend on compatibility. If the compatibility is good, obtaining all the abilities of the character card will not be a problem. If the compatibility is bad, then at most you can only use one or two moves.

He's already come up with a name for this tower: Tower of Hope!

Yes, we still need to pay attention to copyright, after all, it's Tencent...

Flounder: "Hey, this is a multi-world trading platform! You can use it to trade with people from other worlds—anything is possible!"

Other worlds?!

Butterfly was startled, and then immediately became suspicious.

Smiling Butterfly: "Other worlds?"

Smiling Butterfly: "Sorry, I don't think I've ever heard of such a rumor before!"

Flounder: "Honey, that's because your world is so backward, it's normal that you don't know."

Veins bulged on Shinobu's forehead; anyone would be annoyed to be told that their world was backward.

But then she thought about it again and couldn't help but fall into deep thought.

If it really is another world, are there more efficient ways to eliminate ghosts?

Or perhaps Muzan Kibutsuji could also...

Smiling Butterfly: "Since it's a transaction, let me ask you, do you have anything that can kill ghosts?"

ghost?

Yuki raised an eyebrow. He vaguely remembered that Demon Slayer was about killing demons, so he typed in a flurry of words.

Flounder: "Yes, brothers, yes, but I don't know what form the ghosts in your world take. Are they physical ghosts or ghosts in spirit form?"

What is a ghost in spirit form?

Could there be other undiscovered ghosts?

Shinobu Kocho was having a bit of a headache. One physical demon had already caused chaos on their side, and if another one appeared in spirit form, wouldn't they be doomed?

Smiling Butterfly: "What is a ghost in spirit form?"

Flounder: "This is complicated to explain, I'll just send a trade request."

Soon, a message appeared in front of Shinobu Kocho.

"The flounder is inviting you to a trade: Party A will provide one copy of Sadako, and Party B will provide a copy of itself."

Do you agree?

After hesitating for a moment, Shinobu Kocho clicked "agree".

In an instant, all her strength was drained, and she stumbled and fell to the ground.

"What...what's going on..."

She gritted her teeth, forced herself to stand up, and suddenly noticed a blue card on the ground.

She picked up the card with trembling hands, and instantly a chilling aura surged from her fingertips and filled her entire body.

She couldn't help but shudder and looked at the card.

A woman in white, her face completely obscured by her hair, reaches out her hand as if to pass through the card...

"Another one done!"

Yuki chuckled and spun the white card in his hand.

Although it's a white card, it was obtained by exchanging Sadako, so it's a huge profit.

Sadako is very strong, but not very useful, mainly because she is bound by rules and can only be activated through a certain medium to unleash her full power.

As for whether there are telephones in Demon Slayer... don't worry, Sadako will find a way to solve this problem.

The card depicts a girl with lifeless eyes, wearing a haori with butterfly wing patterns, black hair fading to purple, and a katana at her waist.

"Okay, we have four now, six more to go."

"Give it your all, and we'll finish it in one go!"

That's what they say, but the remaining characters...

Yuki stroked his chin, thought for a moment, and then opened a chat window.

Flounder: "Is the village chief here, village chief?"

The oldest fat tiger: "You mongrel, all you can do is bark and howl behind this light curtain."

Flounder: "Now you have a chance, Village Chief! I can let you descend here in the form of a clone!"

Oh?

In a vast white space, a figure shimmering with golden light sat on a throne, resting his chin on his hand, watching the light screen before him with great interest.

"A clone?" Gilgamesh pondered. "Could it be the Holy Grail War?"

"Interesting. Let me see what this thing is that even my all-knowing and all-powerful star can't see through."

Gilgamesh, the all-knowing and all-powerful star, is like his name suggests. There is nothing in the world that Gilgamesh cannot see through, but there is this little chat window that he cannot figure out its origin.

Soon, a card was formed in Yuuki Risa's hand.

He looked at the gold card in his hand with mixed feelings and sighed, "The village chief is a kind man!"

The card depicts a blond man with his upper body exposed, covered in bright red markings, holding a strange weapon.

She agreed to his conditions without paying anything in return.

If I'd known this guy was so easy to fool, I should have talked to him more. All he does is spout nonsense, as if anyone can do that…

Yuki Ryo put the card away with some annoyance. If he could have tricked this card earlier, he wouldn't have had to work so hard on missions and training; he could have just taken off!

However, to be honest, I'm sure I'm not compatible with Gilgamesh, so even if we fused, it probably wouldn't be of much use.

Thinking this way, he instantly felt at peace.

"Okay, next..."

Looking at the remaining contact list, Yuuki Risa was a little worried; there were just too many high-level fighters on it.

Two gold cards, two blue cards, and only one white card—that won't do.

"I need to get another white card..."

He carefully searched for the people he wanted to contact, and suddenly a name appeared before his eyes.

"I remember this guy..."

Yuuki stroked his chin thoughtfully: "I remember this guy has some fighting ability, barely qualifying him as a Blue-rank fighter, but..."

But this is cilantro providing the sound effects!

He thought about how funny it would be if the black cat bumped into her...

Although their training is important,... having fun is important too!

Just do it.

Flounder: "Guardian of Justice, are you there?"

The other party quickly responded.

Justice Dog: "It's Mr. Yuuki! I'm studying with my teacher!"

Flounder: "So you are a messenger of justice. I've encountered a small problem and need your help."

Justice Dog: "Just tell me, I'll do everything I can to help!"

He's a good person, as long as he doesn't go crazy...

Flounder: "I have a group of students whose combat experience is too low. If they were to go to the battlefield rashly, they would probably die. I would like to ask you to help train them."

Justice Dog: "!!!"

Justice Dog: "That's possible, but I'm still learning myself, I'm afraid I won't be able to teach it well..."

Flounder: "You're too modest. Their practical experience is too low, practically nonexistent. I think you can definitely be a great help!"

Justice Dog: "Well... okay then!"

"Flounder is inviting you to a trade: Party A will provide a complete set of Spider-Man comics, and Party B will provide a copy of itself."

Justice Dog: "Mr. Yuuki, what is this Spider-Man comic?"

Flounder: "You can understand it as the biography of a hero."
