Chapter 323 Demon Slayer

"What should we do with this sealed demon now, Miss Lan? How long do you think it'll be sealed for? And is there anything else we can do?" Yuan asked her afterward. It would be disastrous if the demon becomes unsealed a few days later if he doesn't take care of it properly now. However, he also didn't want to accidentally break the seal.

"It depends on how powerful your sealing technique is. Looking at it right now, the demon should remain sealed for a few hundred years." Lan Yingying looked at the fully petrified demon with a feeling of awe and admiration for Yuan, who sealed a demon as a Spirit Warrior.

"However, I think you should still take care of it entirely. You know that technique you used during your second free strike? Do you think you can completely obliterate the demon with it?" Lan Yingying then asked him.

"It won't break the seal if I hit it in this state?" Yuan asked just to make sure.

"It'll be fine. Even if your attack doesn't kill it, the seal won't be undone, and the demon won't be able to regenerate until the seal is completely gone, so you can take your time killing it. That's why demons are so afraid of sealing techniques." Lan Yingying explained to him.

"I see… Okay, I'll destroy it completely so it won't be able to cause any more trouble for you in the future." Yuan nodded before distancing himself from the sealed demon.

Once he was far enough, Yuan held the Empyrean Overlord in front of him and took his time to gather his spiritual energy.

Lan Yingying's eyes widened when she saw this and realized that Yuan's previous Heaven Splitting Sword Strike wasn't at its full power despite showing immense strength— enough to kill a demon.

At this moment, Yuan's body was gushing with Sword Aura, and the sword in his grasp was glowing a beautiful golden color.

[Heaven Splitting Sword Strike!]

Once he'd gathered enough spiritual energy, Yuan released his ultimate attack at the demon and completely covered its entire figure this time.

Under this intense power, the demon's figure quickly disintegrated until not even a speck of hair remained.

Lan Yingying swallowed nervously at Yuan's destructive power, as it was unlike anything she had experienced before.

After killing the demon, a notification appeared in front of Yuan.

[Congratulations! You have slain a Demon, obtaining the title 'Demon Slayer'!]

Meanwhile, outside the Mystic Realm, an announcement appeared in the skies for the players to see.

[Player Yuan has become the world's first player to have killed a Demon!]

The players wondered what a demon was and how they are different from magical beasts.

"Feng Feng, what's a Demon?" Meiuxiu asked her after seeing the notification.

"Huh? A fiend? Why are you suddenly asking about fiends? They are incredibly evil and powerful beings that used to rule the cultivation world." Feng Yuxiang looked at her with raised eyebrows.

Demons are also known as fiends, and they used to run rampant in the cultivation world.

"Well… Yuan just killed a demon inside the Mystic Realm, so I'm asking," Meixiu revealed this to them.

"What?! He killed a demon?! How is that possible?!" Feng Yuxiang's eyes nearly popped out of their sockets after hearing Meixiu's words.

"Demons have heaven-defying regenerative abilities and cannot be killed by normal means! Even the weakest demons are as strong as a peak Spirit Master! I know the Young Master is incredibly talented, but he doesn't have what it takes to kill a demon— at least he shouldn't!"

"W-Wait a second… There are demons in the Mystic Realm? How come no participants have encountered one until today? And I thought they went extinct after the Demon Sealing Clan purged them from the cultivation world…" Long Yijun mumbled in a dazed voice.

"The Mystic Realm is an ancient treasure so it's not impossible that there might be some demons inside. However, to actually run into one and even kill it… Disciple Yuan is an entirely different type of existence…" Elder Xuan said.

"I still can't believe it… How did the Young Master kill the demon? One must either know demon sealing techniques or have special spiritual energy that has divine attributes. However, I know for sure that the Young Master's spiritual energy doesn't have any divine attributes because I didn't sense it in his blood." Feng Yuxiang said, as she'd tasted his blood before.

"Then it could only be the demon sealing techniques…"

However, Xiao Hua shook her head and said, "Xiao Hua has been with Brother Yuan even before he was a cultivator and she doesn't recall Brother Yuan learning any techniques that allow him to seal demons…"

Because she'd been separated from Yuan in the Myriad of Techniques, Xiao Hua wasn't aware that Yuan had learned the Demon Sealing Strike.

"No matter how the Young Master killed that demon, I'm relieved to hear that he's safe despite encountering a demon. I still remember my first encounter with a demon in the upper heavens. It was a terrifying experience, to say the least…" Feng Yuxiang sighed.

"Eh? Madam Feng… You came from the upper heavens? And demons still exist in the upper heavens?" Elder Xuan looked at her with a surprised expression.

"Unfortunately, they still exist. They're just not as active and always in hiding… And yes, I came from the upper heavens. Due to circumstances, I am now here…" Feng Yuxiang sighed.

"I-I see…" Elder Xuan nodded.

Meanwhile, inside the Mystic Realm, at a place isolated from the rest of the world, a red-skinned figure lifted its head to look at the cloudy sky with a narrowed gaze as it sat on a red throne.

"That fool perished… Did he get too full of himself and went too deep into that man's Sword Aura? Even though I specifically warned him to not get ahead of himself." This demon mumbled, yet it expressed no sorrow after knowing that a fellow demon had just died.
