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

Lister had already analyzed the two powers of death energy and annihilation during the battle of White Moon Castle, but Aizen not only wanted the energy but also wanted to observe the individuals who used these two powers.

After the conversation, Lister promised to accompany Aizen on a trip to obtain experimental samples, because he simply couldn't bear to let Aizen go out alone.

Who knows what Aizen might do?

He also needed to ascertain the situation of the Kingdom of Rennes after the war, so he decided to do both things at the same time.

And because he might encounter refugees during the investigation, he also needs to plan how to receive them.

Thinking about these things, Liszt seemed to see his hair falling out like crazy in the future.

Suddenly, a pair of icy hands pressed down on his head.

Beside him, Muzan was smiling, and his smile was actually quite sweet.

The pressure she applied with both hands was just right.

But if you can use Blood Demon Art to relieve someone's physical fatigue, why use massage instead?

"Dong dong dong."

Suddenly, there was a knock on the office door, and Elsa, a fox-eared maid wearing a semi-transparent gauze nightgown, opened the door.

"Master, it's already eleven o'clock. You must be very tired today. Please get some rest."

Lister immediately removed Muzan's hand and stood up.

"Okay! I'll go back to my bedroom right away!"

"Goodnight, Muzan!"

Muzan watched as Lister strode away. After the door closed, prominent veins appeared on her face, and even her fangs were showing.

The only time she could find peace and tranquility was...

...Never mind, overreacting will displease Lister.

After thinking for a moment, Muzan sat down in Lister's chair and stroked the notebook beside him with both hands.

These are drafts of Liszt's past work. Nowadays, Liszt only uses the system to draft, and he keeps only one copy of the official documents.

"That's amazing."

“It’s only been a day since our heart-to-heart talk last night, and I already feel like I’ve changed a lot.”

"Liszt, if I study your thoughts and knowledge, can I possess the same wisdom as you?"

……

Lister was naturally unaware of Muzan's psychological changes; he was indeed tired today.

Last night, they rushed to Baiyue City to rescue their family. This morning, they prepared to fight the enemy again, cheered for Ban, and held a meeting after the battle, racking their brains to analyze the situation for Ban.

Really tired.

After taking off his clothes, Lister rested his head on Elsa's large breasts and listened to Nadia's soft moans as he slowly fell asleep.

Early the next morning, Liszt began preparing for the day's operation.

He first sent Elsa to Red Maple Town to find Chris and Pauline, and then used his mental powers to notify Yahiko, Minami, and his sister Melf to act together.

Upon hearing that they were going on an outing, the leader of the Epsilon research team stationed in Red Maple Territory expressed his desire to accompany them, so he brought along three more researchers.

Around nine o'clock, everyone gathered in the courtyard of Red Maple Castle.

"Mr. Aizen, do you have a strong need for samples?"

Aizen smiled and said, "There aren't too many requirements. The higher the strength, the better, but ordinary strength is enough."

That's good.

Lister did not want to provoke the foreign races too much.

If he shows a tendency to expand outwards, these powerful alien races may react in ways that are difficult to predict.

Therefore, it's better to be safe this time.

He left behind the Flying Thunder God mark along the way when he rushed to the aid of White Moon City.

Considering that only a day has passed, the enemy should not have gained a foothold yet, so let's go to the edge of White Moon Territory.

Then Liszt used the Flying Thunder God technique.

After several jumps, the group successfully reached the edge of White Moon Territory and landed in the center of the army of corpses.

Seeing at least several thousand ghouls moving around him, Lister fell silent.

They actually occupied the entire White Moon Territory so quickly?

Given this number, and considering the presence of intelligent undead mages within the ghoul horde, it will likely take some time to clear them out.

Just as Lister was thinking this, Aizen suddenly raised his hand, and a powerful spiritual pressure spread outwards. The black light in the eyes of the ghouls that were nearby dissipated, and they collapsed to the ground.

At the same time, a black sphere appeared at Aizen's fingertip.

The Demonic Path? It seems to be the Demonic Path that didn't appear in the original work.

"Hado No. 90 - Modified - Shadow Black Coffin".

Darkness enveloped the surroundings.

The shadows spread rapidly outwards, and black blades emerged from them, piercing through the ghouls. Even the undead mage who screamed and activated a pale black shield was pierced through by hundreds of blades and pulled into the shadow space.

Just three seconds later, the thousands of undead that had surrounded the crowd vanished without a trace.

Aizen gently pushed up his glasses.

"One more is missing."

······

This is a sense of oppression that is completely different from the overwhelming destructive power of Madara's ninjutsu.

The all-consuming darkness sent a chill down the spines of everyone present.

Liszt broke out in a cold sweat.

From the initial mirror clone to the black coffin, which is clearly an improvement upon the power of shadow...

Aizen is absorbing nourishment from this world and growing stronger!

“Lister, I have sensed the specimen that uses Annihilation, and I will be back soon.”

Very fast indeed.

In less than two seconds, Aizen reappeared in front of everyone.

"I have achieved my goal, so I'll take my leave now."

"I will bring the items I traded next time I come."

Subsequently, Lister sensed Aizen's aura moving towards Red Maple Territory at an extremely fast speed, almost as fast as the Flying Thunder God Technique.

In less than a minute, Aizen had crossed the snowfield, arrived at Red Maple Territory, and returned to the world of Bleach.

Liszt frowned deeply.

He thought that with his own rate of progress, he would eventually be able to make Aizen take him seriously, but Aizen, who had already reached the limit of a Shinigami, was still improving...

What should he do to gain Aizen's further approval?

How to do?

Just as Liszt was troubled, Melf suddenly stepped forward and placed her hand on his forehead.

"Are you alright? You don't look well."

Lister was jolted awake and realized that others, including Melf, Elsa, Yahiko, Konan, Chris, and even the newly joined Pauline, were looking at him with concern. Muzan was also standing less than half a meter away from him, ready to help at any time.

...Yeah, why think so much about Aizen?

His ultimate goal was never to gain Aizen's approval, but to develop his territory and make the people within it happy. Gaining Aizen's approval was merely a means to achieve his goal.

"Sorry, I was just overthinking it."

"Let's go do something else now."

Lister surveyed his surroundings, then looked at Pauline.

"Pauline, are you familiar with this area? Where is the nearest village?"

Pauline nodded immediately and pointed northeast.

"Lord Lister, the nearest village is Bailu Village."

Lister used his magic eye to observe the direction and saw a village in ruins. He could not see any signs of burned food or even corpses, only dried bloodstains and dilapidated houses.

The food was useless to the undead, so it was probably collected and given to the orcs.

The absence of corpses likely indicates that the undead took them to cultivate death energy.

After all, death energy can only be produced through the decay of living things, and the undead, who have not appeared for a long time, must have cooperated with the alien races in order to create large-scale tombs.

The undead... once we have some free time, we must get rid of them.

"The village has been attacked, Pauline. If there are any survivors in the village, which way do you think they would run?"

Ugh?

Pauline scratched her hood.

“I remember that the Dark Court’s logistics personnel were active in Bailu Village. If I go there, I should be able to find some traces.”

"Okay, let's go then."

Bailu Village was not far away, only three kilometers away, and the group arrived quickly.

Pauline immediately used her shadow abilities to search for clues, while the others also observed.

Melfie, Chris, Yahiko, and Minami all wore expressions of extreme resentment.

The damaged houses and bloodstains everywhere suggest that the village was likely massacred when it was attacked.

The orcs vented their anger from four thousand years ago on humans and orcs.

“Lister, I can help you find the living.”

Muzan raised his hand, and a drop of blood dripped from his fingertip.
