"A bunch of useless guys!"
Inside the Infinity Castle, Kibutsuji Muzan suddenly opened his eyes, an angry expression on his face.
"They talk big, but when it comes to doing actual work, not a single one can do it right!"
Especially Kokushibo, who boasted so much about how his next strike would definitely hit Lin Que.
But in the end, just like those other useless ones, he was instantly killed by the opponent!
Bang—! Bang—! Bang—!
Smashing all the surrounding furniture and even the floor, Kibutsuji Muzan, having vented his anger, temporarily calmed down.
Although Kokushibo and the others' performance was embarrassing, making him feel disgraced.
However, after remotely watching that battle, Kibutsuji Muzan had to admit one thing.
In this world, another monster had appeared.
And it was a monster far surpassing Yoriichi Tsugikuni from back then.
"I need to find a place to hide and avoid him."
"At most, it will be a hundred years. It won't be too late for me to act after that guy dies of old age."
Kibutsuji Muzan narrowed his eyes, looking at the room not far away.
He had no luggage to pack; the only thing he needed to do was get rid of the demons who knew his whereabouts.
For example... Narume.
With a thought in his mind, Kibutsuji Muzan no longer hesitated.
He took a step and walked towards Narume's room.
However...
Before he could reach Narume's room, the previously closed door suddenly opened first.
The next second, a figure that surprised him walked out from inside.
"Yo~ Good evening~!"
Lin Que smiled and waved: "This should be... um, our third meeting, Kibutsuji Muzan."
Kibutsuji Muzan: "?!!"
How could this guy be here!
"Because I came to find you."
Hearing the voice in his mind, Lin Que replied with a smile.
"As the saying goes, it's rude not to reciprocate."
"Since you sent the Upper Ranks to kill me, I naturally have to return the favor properly~"
Words laced with a hint of a smile fell into Kibutsuji Muzan's ears, but they sent a chill through his body.
Why did the other party know his thoughts?
Before he could ponder this question, a wave of deathly aura surged towards him, reminding him of the scene when Kokushibo and others died not long ago.
Without any hesitation, Kibutsuji Muzan activated his strongest life-saving skill,
Self-destruct!
With a muffled sound, Kibutsuji Muzan's body unexpectedly exploded into 1800 pieces, scattering in all directions.
"Don't be in a hurry to leave."
Lin Que's figure disappeared from where he was, and the next moment he reappeared, holding Muzan.
"You?!"
Kibutsuji Muzan looked at Lin Que with a horrified expression.
He had thought that the other party might, like Yoriichi Tsugikuni, chase after his body fragments, or launch a large-scale attack to try and wipe them out.
But what the other party actually did was even more outrageous than he had imagined.
This guy actually grabbed all his fragments in an instant, and even pieced them back together like a jigsaw puzzle!
"Relax, I won't kill you immediately."
Taking out a sealing rope from the Blessing Card, Lin Que tied Kibutsuji Muzan up.
"You're still somewhat useful right now."
Discovering that the power within his body had disappeared, Kibutsuji Muzan's expression turned ugly: "What do you want to do?"
Lin Que replied: "Search your memories."
Kibutsuji Muzan was not a born demon.
He became a demon in the Heian period after taking medicine from a doctor.
This was a very magical thing.
One must know that Kibutsuji Muzan was originally just an ordinary person.
Just by drinking a bottle of medicine, he gained power comparable to a top seven-digit or even close to a six-digit existence.
As soon as he thought of this, Lin Que's eyes began to glow as he looked at Kibutsuji Muzan.
This wasn't a Demon King; this was a God of Wealth!
After killing that doctor, Kibutsuji Muzan had indeed found the potion's formula on him.
As long as Lin Que could obtain Kibutsuji Muzan's memories, he would naturally also obtain the potion's formula.
Then, by cultivating the necessary ingredients for the potion in the unnamed territory, the unnamed territory would have a continuous source of wealth.
After tying up Kibutsuji Muzan, Lin Que fully activated his Observation Haki.
After breaking through Kibutsuji Muzan's mental barrier, Lin Que began to examine the other party's memories.
The search process was not troublesome; the disparity in mental strength between Lin Que and Kibutsuji Muzan was simply too great.
He found the formula for that potion with virtually no obstruction.
"So it's called Evolution Potion."
After incidentally learning the name of the potion, Lin Que's face showed a look of emotion.
"It's not a misnomer, I suppose."
Extraordinary physical qualities, terrifying regenerative abilities, and profound Blood Demon Arts.
Not only that, demons created through the complete version of the Evolution Potion had no obvious weaknesses.
They didn't need to eat humans and weren't afraid of sunlight.
To kill them, one could only destroy every last cell of them head-on.
Such an existence, to be called a higher-level life form after evolution, was not an exaggeration at all.
"Now I just need to get the cultivation methods for the various materials, and then I'll be done."
Lin Que looked at Kibutsuji Muzan: "Are you ready to go?"
"Don't kill me!!"
Sensing the change in Lin Que's attitude, Kibutsuji Muzan spoke in a panic.
"I can help you!"
"I'm not interested in men."
Lin Que lazily yawned: "Is that your last wish?"
"Wait..."
Bang—!
[Group member 'Sea King' has killed the Demon King 'Kibutsuji Muzan', world prestige increased by 550 points, rewarded 22000 group points.]
"Not bad."
Lin Que nodded with satisfaction.
After killing Kibutsuji Muzan, the world prestige, as expected, reached its limit.
"This can be considered complete now."
The 40000 points obtained through world prestige, the See-Through World technique gained from Kokushibo, and the Evolution Potion formula from Kibutsuji Muzan.
Aside from the breathing technique training method that Yaozai Ubuyashiki hadn't prepared yet, Lin Que had basically acquired all the useful things in this world.
If he had to mention anything else, it would only be the Demon Slayer Mark and the Red Blade.
However, for these two things, the former's activation method was already given in the original work, and the latter was basically useless, not worth Lin Que's effort to specially collect.
"Calculating the time, Kanae should be waking up soon."
Recalling what he had said to Butterfly Shinobu earlier, Lin Que's figure disappeared from where he was.
He was a good man who kept his promises; he would first pick up Kanroji Mitsuri, who was still in Tokyo, and then return to the Demon Slayer Corps.
There was still some time, so he would go back and enjoy the feast Kanae had prepared for him.
Things like abalone seafood, sashimi, and oysters, he should be able to taste them all.
