What... is going on?

"Now I want to tell you about another concept, which is kinetic energy. You can understand kinetic energy as the energy contained in an object in motion."

As he spoke, Mo Mo gave a light kick, and a pebble flew high into the distance, disappearing without a trace.

"With kinetic energy, a stationary object can move. Without kinetic energy, a moving object will remain stationary."

This time, Yuuka Kazami seemed to understand correctly and nodded.

"The kinetic energy of matter is directly related to its mass. If you want something to move, you must give it kinetic energy. The greater the mass of the matter, the greater the kinetic energy required to make it move."

“And this,” Momo pointed to the feather in Kazami Yuuka’s hand, “is why the feather can remain still in your hand, but you can’t make it move even slightly.”

After a few seconds of processing, Kazami Yuuka asked, "Is this your ability?"

“That’s right,” Momo nodded and said, “My ability is called Undifferentiated Matter. You can understand it as my ability to create substances with special properties.”

"And this feather in your hand is one of the results of my creation. Under my power, it can be transformed into a substance with extremely large mass, yet unaffected by gravity."

"This means that this tiny feather can be heavier than a mountain, yet it can be as light as a real feather, or even lighter, and can float in the air."

Upon hearing this, Yuuka Kazami's eyes widened. She finally understood where she had gone wrong. Looking at the feather in her hand, she tried again with all her might to move it, only to find that the feather was indeed as heavy as a mountain.

"But……"

Kazami Yuuka seemed to have thought of something and said, "How did you make it move so freely? Moving it requires a huge amount of kinetic energy. Are you strong enough to carry the countless mountains behind you?"

Mo Mo looked at Kazami Yuuka in surprise. As expected, Kazami Yuuka was a relatively modern yokai among the great yokai, and she understood things very quickly.

“This,” Mo Mo smiled faintly, “This involves the specific application of my abilities. This feather can indeed exhibit great mass and zero gravity, but I can also adjust it, or even combine and reshape it to give it other properties, but you just can’t see any of that.”

This time, Mo Mo didn't explain clearly, and Kazami Yuuka didn't delve into it, because it clearly involved Mo Mo's abilities. Even if Mo Mo had explained, she probably wouldn't have understood it at that point.

Right now, Kazami Yuuka is barely managing to understand Momo's words by guessing and deciphering. As for fully comprehending what Momo is saying, that would probably be an enormous challenge for her.

"Could you show me the power this feather was originally meant to possess?"

After a few seconds of silence, Kazami Yuuka looked at Mo Mo, the hatred and hostility in her eyes lessening, replaced by a hint of doubt and scrutiny. She made a request that surprised Mo Mo, a request that Mo Mo readily agreed to.

"No problem, please let go."

Kazami Yuuka nodded, pulling her hand away from under the feather, which floated in the air as if it could drift away at any moment.

But at that moment, something unexpected happened. The feather, which had been as light as a feather, suddenly seemed to become heavy and fell to the ground in a free-fall motion.

"boom--"

A massive tremor occurred again, no less severe than the collision between Momo and Kazami Yuuka earlier. The entire earth shook, as if a mountain had fallen from the sky, triggering a high-level earthquake.

After a cloud of dust settled, all that remained where the feather had fallen to the ground was a dark, feather-shaped hole, bottomless, clearly formed by the feather hitting the ground directly.

A plume of black smoke, smelling of sulfur, billowed from the cave entrance and lingered for more than ten seconds before disappearing. This smell of black smoke was almost the best proof of where the feather had been.

"I lost."

Seeing all this, Kazami Yuuka understood Mo Mo's abilities from the most direct and comprehensive perspective, and also completely figured out where she had lost.

She was confident that she had lured Mo Mo into a trap and was trying to kill him with one blow. This seemingly mature battle strategy was actually the most foolish move because she completely ignored Mo Mo's abilities.

Momo's abilities were so powerful that she had no way to fight back and had no choice but to admit defeat.

Kazami Yuuka showed no dissatisfaction with this; after all, losing was losing, and it wasn't a big deal, especially since it wasn't the first time she had lost.

Mo Mo secretly breathed a sigh of relief. Although he had just barely defeated Kazami Yuuka, he had actually borrowed the powerful energy of Kazakiri Hyōka. Otherwise, Mo Mo alone would not have been able to apply the Unreal Matter to this level.

To put it bluntly, Kazami Yuuka just lost to the combined 2.3 million Level 3 and above Ability Users of Academy City, enhanced by the Neural Link Device, not to Momo alone.

However, some things don't need to be said; just show off when it's time to do so.

Look, right now, the way Kazami Yuuka looks at Momo is exactly the way she looks at a strong person, even with a hint of respect in her eyes. This is the result of Momo's skillful use of strategy.

"Alright, now, Ms. Kazami Yuuka, can we talk?"

085 Sorry, I refuse.

Now that the fight was over, Mo Mo finally had a chance to talk to Kazami Yuuka in a relaxed manner. Obviously, Kazami Yuuka wouldn't easily attack Mo Mo again right now.

At least, she won't do anything pointless until Yuuka Kazami finds a way to defeat Momo.

And Momo's actions were not superfluous.

On one hand, Yuuka Kazami's personality makes it impossible for her to have normal conversations with Momo. Of course, if Momo behaves like an ordinary person, Yuuka Kazami won't harm him, but Momo shouldn't even think about getting close to this great youkai, Yuuka Kazami.

On the other hand, there's Momo's reflection on why Kazami Yuuka is here.

Without a doubt, among all the guests from Gensokyo who have appeared in the afterlife, Kazami Yuuka is the most special, even more so than Houraisan Kaguya.

Kaguya Houraisan was likely a living person from Hourai, retaining some of her power, which allowed her to come to the afterlife, impersonate someone from the afterlife, and naturally retain her memories of Gensokyo.

In this way, if Kaguya Houraisan hadn't lost her memory, Momo would definitely have been able to learn a lot of information about Gensokyo from her.

Unfortunately, the Moon Princess Penglai has now become Mo Mo's beloved daughter, and she can't wait to keep pestering Mo Mo for kisses.

Sigh... What a troublesome daughter, I might as well just throw her away.

However, compared to Kazami Yuuka in front of Mo Mo at this moment, Houraisan Kaguya's special qualities are nothing at all.

After all, Kaguya Houraisan is currently suffering from amnesia, and Mo Mo cannot know for sure what Kaguya Houraisan was in before. He can only deduce that Kaguya Houraisan likely knew a lot about Gensokyo.

In contrast, Mo Mo was almost 100% certain that the Kazami Yuuka in front of him was likely acting on orders or requests from Yakumo Yukari to guard this mysterious NPC who could influence the world, preparing for their subsequent plans.

In other words, what Mo Mo wants to know, Kazami Yuuka in front of him probably knows not only all of it, but she may even be a witness from the beginning, and may very well be Mo Mo's enemy at the moment.

All these factors led Mo Mo to finally take action and fight a fierce battle with Kazami Yuuka. At the same time, he took the opportunity to use the power of his Unreal Matter to make Kazami Yuuka acknowledge Mo Mo's power, thus giving the two a chance to communicate.

What should we talk about?

Upon hearing this, Kazami Yuuka frowned slightly, a hint of wariness and doubt flashing in her eyes.

Mo Mo found her expression amusing, because at first, when Kazami Yuuka saw Mo Mo, she was filled with piercing hatred, as if Mo Mo had become the heartless person who had betrayed Kazami Yuuka.

Now, Kazami Yuuka seems to have sensed something. Her almost insane hatred for Momo has disappeared, replaced by more doubts about Momo himself. She seems to be pondering Momo's origins and purpose.

Kazami Yuuka didn't just answer Momo with words; she also responded with actions. With a gentle wave of her remaining hand, she summoned the flowers, which had been reduced to fragments, to her front.

These plants were all cultivated here by Yuuka Kazami, and what was once a beautiful garden beneath their feet has now become a huge, deep pit.

Immediately afterwards, the flower branches that had already turned into fragments withered away in an instant, releasing a pale green power.

Yuuka Kazami grasped this power and channeled it into her shattered right arm. And then, a miracle occurred: Yuuka's shattered right arm suddenly reappeared, as if it were an illusion, just like her severed arm had been.

"Very impressive."

Mo Mo stared in astonishment at this ability, which seemed to be absent from the original work, expressing his surprise and admiration.

"With such power, you truly deserve to be called the Lord of Flowers in All Seasons. Or perhaps, you are a part of flowers and nature itself. As long as you are in nature, surrounded by flowers and green leaves, you possess inexhaustible demonic power?"

Kazami Yuuka didn't answer Momo, just as Momo hadn't answered her about the details of Momo's abilities. She raised her newly formed arm, examining its condition, looking at its fair skin and smoothness like a newborn baby's, and finally nodded in satisfaction.

You're right about one thing.

Kazami Yuuka lightly stepped on the ground, quickly crushing the stones and gravel into powder. The crater that had been slowly created by a feather was also covered up by Kazami Yuuka, seemingly because she disliked the sulfurous smell emanating from it.

"My power is indeed limitless."

Kazami Yuuka said these words in a calm tone, but Mo Mo smiled even more brightly. This bright smile earned her Kazami Yuuka's uncompromising hostility.

"you do not believe?"

"I was willing to believe it."

Mo Mo shrugged and said, "Although I understand your predicament, please don't do things that are inconsistent with your identity and character, okay? You are Kazami Yuuka, one of the most powerful youkai in Gensokyo. Uprightness and honesty are your style."

"Your current bluster only makes me feel that your image is crumbling. Do you understand?"

Kazami Yuuka's pupils contracted slightly, and she remained silent.

"Still not giving up?"

Momo held up a finger and said, "Actually, I know Gensokyo much better than you think, I know everything about you, including your abilities."

"In a sense, your abilities are indeed very strong. You can become one with flowers, plants, and nature, and by losing the boundaries of your own body, you have gained tremendous power. Unless someone can wipe out all of nature in an instant, it will be difficult to confront you head-on."

Am I right about all of this?

Kazami Yuuka, who had been silent, raised her head and looked at Mo Mo's smiling face, saying, "If you really knew all this, you shouldn't be my enemy even more. I was just momentarily unaware of your abilities, but next..."

Kazami Yuuka's voice disappeared because she noticed a hint of disappointment in Mo Mo's eyes.

Was it really that easy to see through?

Kazami Yuuka felt somewhat resentful, but she was too lazy to continue bluffing. In front of Mo Mo's all-seeing eyes, such bluffing would only make her seem intellectually inferior to him.

This feeling is very unpleasant.

Moreover, as Momo said, such behavior was more suited to Yakumo Yukari, not her. What she was best suited to do was to defeat all the enemies in front of her at once.

Unfortunately, facing this seemingly thin, jovial boy, Kazami Yuuka had lost all confidence.

What kind of power could she possibly use to shake a man whose wings are made of countless mountains? Faced with such a powerful man, even if Yukari Yakumo came, she would probably be powerless.

"Want to know how I knew you were bluffing, and how I came to that conclusion?"

Mo Mo pressed on, and Kazami Yuuka instinctively replied, "Isn't it because you understand us?"

"Do not."

Mo Mo sighed softly and said, "It's just because this isn't Gensokyo. Ms. Kazami Yuuka, no matter how strong you are in Gensokyo, even if you use your power to bloom flowers in this afterlife, this is still not your home turf."

“Here, you are always just an outsider, just like us.”

Kazami Yuuka fell silent once again. Without a doubt, Momo was right again.

Yuuka Kazami has now entered the afterlife, which is not only not Gensokyo, but also completely unrelated to the larger world where Gensokyo is located. This means that if Yuuka Kazami wants to use her demonic powers, she will inevitably have to go against the rules of this world.

If it weren't for Yukari Yakumo's help, Yuuka Kazami would even doubt whether she could create her own garden in this afterlife.

"You seem to know everything."

Kazami Yuuka responded nonchalantly, with a hint of sarcasm. Mo Mo, unperturbed, said, "I don't know everything. I just learned a lot of basic information because I was interested in you. It's like wanting to enter Gensokyo but not knowing how."

After saying this, Mo Mo looked at Kazami Yuuka expectantly, hoping to see more expressions on her face. However, Mo Mo was disappointed. It seemed that Kazami Yuuka had also figured out Mo Mo's thoughts and began to maintain an icy expression.

"who are you?"

Not only did Kazami Yuuka not respond to Mo Mo's words with any expression, but her tone also seemed to turn cold. She stared at Mo Mo, and the two seemed to have returned to a tense standoff.
