In this crossover anime, many ruthless and powerful figures reside in my territory.

"Pleasant to work with."

The two shook hands, both appearing to be in good spirits.

Lister handed over his physical data, which was of little use to him, in exchange for a large amount of weaponry and a trump card in the war.

Yuri, on the other hand, obtained a key to unlock new super soldier research.

The gains from this trip to another world far exceeded Yuri's expectations. He had originally intended it as a safe house and a place for quiet contemplation, but it seems necessary to make more investments.

There is no direct conflict of interest between him and Liszt, so there is no need to worry about being betrayed. On the contrary, they can complement each other, so why not cooperate?

[Congratulations, Master! You have gained Yuri's approval, unlocking the new achievement "Yuri's Collaborator".]

[Achievement Reward: You can now cultivate mental power and use mind control to implant a thought imprint.]

The power of the mind!

Lister's already good mood improved even more.

The Mental Omega series mentions that mental power is a potential possessed by everyone, which can be acquired through training to become a superhuman.

However, some people are born with strong mental abilities and can do unimaginable things.

For example, Yuri can imprint a thought on people, making them forever loyal to Epsilon, which is also the main way Epsilon increases its soldiers.

For example, the hero unit Malon in Mental Omega can kill people invisibly by using kinetic blades formed from his mental abilities; their power can even tear apart sturdy armored vehicles.

Even ordinary psychic abilities can be used to levitate across rivers.

Psychic abilities can do many things; they can both invade the human brain and exhibit powers similar to telekinesis.

For Liszt, the ability to imprint ideas was naturally the most useful.

and many more!

He gained Yuri's basic favor in less than three hours of conversation. What about Muzan?

Miss Muzan, do you dislike me that much?

As expected, you're just a scumbag who only cares about yourself!

Feeling the strange look in Lister's eyes, Muzan felt something was off. What did that resentful look mean?

She was even more annoyed. Why was she always the one being schemed against?

“Mr. Lister, I need to go back and make some preparations. I will come to bother you again in a few days.”

Yuri bid farewell to Lister and Muzan. He had gained a lot from this trip and couldn't wait to get back into his research.

After Yuri left, only Lister, Muzan, and the taciturn Nakime remained in the arena.

······

Lister looked at Muzan's beautiful face and wondered if he should try to win her favor, hoping to unlock a useful ability related to the physical body.

But after thinking about it, I decided to let things take their course.

Someone like Muzan, who has almost no empathy and has only ever sympathized with people who have had similar experiences to him since birth, shouldn't expect to gain their favor.

Relationships with such people are often stronger when maintained through mutual benefit and power than through emotions.

"Lister, all the villas have been furnished."

"Yes, the progress bar has gone up too."

Muzan sensed the contract within his body and, as expected, saw the progress bar increase by 0.1%.

Although small, it is still hope.

"Will you continue to come with me to exercise, or do you want to do something else?"

Muzan thought for a moment.

The blue spider lily is the most important thing; let's stay here and figure out how to speed up the progress bar.

So Muzan took Nakime back and then returned to continue training Lister.

She smeared her blood on Lister's body to form blood patterns, and then used Blood Demon Magic to double Lister's weight, making it easier for Lister to train under excessive weight than for her to sit on him.

As her blood covered Lister's surface, she sensed the changes in Lister's body through her senses.

Lung breathing, muscle tremors, joint creaking, blood flow, cells releasing energy...

All information about the physical body was received by Muzan.

It was truly a body that made her drool.

Unfortunately, it's not perfect yet.

"Liszt".

"Ok?"

Lister stopped swinging his sword and looked at Muzan beside him.

Her red lips curved into a bright red crescent moon.

Its white, sharp teeth were exposed, possessing an eerie beauty.

"Would you like to make a deal with me?"

Muzan raised his pale right hand, pointing his index finger at his temple.

"You teach me how to cultivate blood and qi, and I'll teach you how to perfectly utilize the power of your body."

"how?"

Chapter 46 Muzan Wants to Take Off

Looking at Muzan's wicked smile, Lister slowly typed a question mark.

You want to make a deal with me too?

Are you starting to get a brain?

Muzan initially had no intention of making a deal with Lister; she simply wanted to obtain the Blue Spider Lily to become a perfect being and fulfill her ideal of immortality.

But she suddenly realized that it wasn't worth it for her to work for Lister for nothing just to get information about the location of the Blue Spider Lily.

He had already shared the information about the blue spider lily with his subordinates, and perhaps there would be some unexpected gains.

If her subordinates actually find the blue spider lily, wouldn't all her efforts in the other world have been in vain?

Therefore, Muzan, who had observed the entire transaction between Lister and Yuri, had his own ideas.

She wants to become stronger!

He became stronger than Yoriichi Tsugikuni!

She wanted both Liszt's blood and this mysterious power called "blood energy," which sounded perfect for her!

Once she completes her evolution again, no one in her world will be able to resist her.

She will become a true catastrophe! An immortal and indestructible catastrophe!

Do you believe that the two conditions you proposed are equal?

"of course."

Muzan slowly walked up to Lister, placed his right hand on Lister's chest, and slowly moved it upwards.

She looked up and admired Lister's face, her fair fingers caressing his neck where blood seemed to pulsate.

"You have no idea how powerful your body is."

“I’ve observed you; your muscle-using skills are still quite crude, even inferior to those demon hunters in my world.”

"They use a technique called breathing to enhance their physical abilities, thereby fighting against us ghosts."

"They are able to use every muscle in their body skillfully and use a variety of targeted moves."

Muzan's fangs grew a little longer, showing that she was consciously restraining her desires.

"Right now, you are only using the energy within your body to power your physical body. Even strengthening your physical strength is done by controlling energy."

"If you can unleash such power simply by relying on energy, what would happen if you also completely control your physical body?"

The fingertips seemed to be caressing Lister's carotid artery with a sense of ecstasy.

"No one can compare to me in terms of understanding the body."

“I can sense every muscle, every blood vessel, and every cell in you.”

"I can calculate the perfect way to exert force with just a little calculation."

Lister grabbed Muzan's hand and pulled it away from his neck.

"That does sound good."

Muzan smiled and withdrew his hand.

"I will teach you methods of physical training, and you will teach me methods of cultivating blood and qi."

"fair enough."

"Besides, you're missing a sparring partner, aren't you?"

"For you, I should be as strong as possible."

?

Wait a minute, could it be that Muzan really grew another brain?

Lister suddenly remembered that Muzan was indeed very clever.

He had a keen ability to sense the negative emotions of others from a young age, and he could persuade all five of his wives to commit suicide simply by using words.

After transforming into a demon, he immediately saw through Kokushiro Tsugikuni's problem and obtained the data on breathing techniques for swordsmen.

He then created three more human identities to help him become the perfect being.

First, there's the geisha, who orders her human subordinates to help her gather information about the Blue Spider Lily.

Secondly, adopting a son ensures the location for research into drugs that overcome sunlight.

Thirdly, there are business owners who accomplish what the other two identities cannot, and use their wives' connections to expand the company's influence, possessing the resources of top-tier successful individuals.
