I have a hero simulator

"Ms. Kanae!"

Shen Yuan came closer, picked her up from the ground, and assessed the extent of her injuries.

"No...it's no use, the poison has already started to spread..."

Black blood was flowing from the corner of Kanae Kocho's mouth, her vision was blurring, and her vital signs were gradually disappearing.

"Maybe it can be rescued."

Shen Yuan frowned, but what Butterfly Kanae said was the truth, she was not far from death.

But if such a gentle and beautiful girl were to die here like this.

Shen Yuan felt that he was somewhat responsible.

Besides, in order to avoid being discovered by Douma, she chose to stay here and fight, which is why she was defeated so quickly.

"Give up... It's too late. I can feel the poison spreading in my body..."

Butterfly Kanae was extremely weak and gasped, "It's so cold... I can't breathe..."

Shen Yuan could feel that Kanae Kocho's body temperature was dropping and her alveoli had begun to necrotize. Douma's blood demon art was extremely terrifying and almost incurable.

At this time, waiting to die is the only option.

"You're not going to die."

Shen Yuan thought to himself, just think of it as me repaying you a favor.

"Why... do you say that?"

Accompanied by the sound of weak coughing, the semi-conscious Kanae Kocho smiled slightly, and then lay on Shen Yuan's body motionless.

"Man's destiny is not predetermined."

Your destiny is in your own hands.

Shen Yuan looked at the system mall, then stared at the gold coins accumulated after defeating Douma and killing three evil spirits, and then stared at the few lit icons among the purchasable items.

"If I don't help someone dying, just to survive, then what's the difference between me and a 'ghost'? Besides, I don't need such a thing right now..."

With a slight movement of his mind, a blood-red potion bottle appeared in Shen Yuan's palm.

He opened the metal bottle and pointed it at Butterfly Kanae's lips, trying to make her drink it.

"Ahem..."

However, Kocho Kanae had difficulty even breathing, let alone opening her mouth.

That being the case.

Saving lives was the most important thing, so Shen Yuan didn't think much about it. He tilted his head back and drank a mouthful of the life potion, then lowered his head and leaned against the black-haired girl, pouring it into her mouthful by mouthful.

Green fluorescence visible to the naked eye appeared around Butterfly Kanae like magic.

She looked as beautiful and dazzling as a fluttering butterfly. A mysterious magical energy was clearing away the poison of vampire magic and completely repairing her cells...

About 15 seconds later, Kocho Kanae's vital signs completely returned to normal and her wounds had healed.

As she regained consciousness, she opened her eyes slightly and looked at the black-haired man whose lips were pressed against hers. Her pupils flickered and she froze in place for a moment.

"Ok?"

Shen Yuan saw that Butterfly Chanehui had opened her eyes, and then raised her head: "Have you recovered?"

"..."

However, the girl was as dazed as a piece of wood, her cheeks slightly red, staring blankly at Shen Yuan.

"Your condition is too serious. Although your injuries have partially recovered, they are not fully healed. You can ask your companions to rescue you."

Seeing that Butterfly Kanae didn't answer, Shen Yuan stood up: "But before that, I should leave."

"and many more."

Butterfly Kanae suddenly stretched out her hands, her eyes regained their clarity, and then she grabbed Shen Yuan's hand: "You saved me, how can I repay you..."

"You and I each have our own destiny, and there's no need to repay."

"You're alone and helpless in a place like this, and you're going to hunt demons next, right? If so, why don't you come with me to the Demon Slayer Corps?"

"I'm a ronin swordsman. I'm used to freedom and don't like being controlled by others."

"Who said you should be inferior to others? Don't you want the Nichirin Blade? Why don't you strengthen your weapon?"

Shen Yuan turned around and saw a spring-like smile on the slightly blushing face of Butterfly Kanae.

He fell silent.

It's a good idea to go to the Demon Slayer Corps and get a few Nichirin Swords for free. You can also get some extra stuff at the same time. Even if you don't use them, you can sell them to the system mall.

After all, Shen Yuan’s hero simulation system is fully functional and quite conscientious.

He can gain proficiency by increasing his level, thereby further inheriting the power of the "Demon Sword Soul". When he reaches level 18, he will 100% unlock the hero's peak combat power during his lifetime.

Once the hero's proficiency reaches the maximum, it will be automatically inherited to the main body without the need for selection.

However, this requires achieving an S-level rating.

The equipment purchased by earning gold coins can be taken to the next world when the simulation world ends.

Therefore, in Demon Slayer, if you can find a way to make money and get an "Infinity Blade", then the next world will start with Infinity Blade. As long as the random hero template is not too outrageous, such as choosing a mage hero, it can be considered a take-off.

Besides, even if it is a mage hero, it is normal for him to have Infinity Edge. If you know a "melee physical mage", he can kill people instantly with a basic attack.

"Oh, by the way, I haven't asked you how you saved me." Butterfly Kanae looked at Shen Yuan curiously with a dazzling smile. She seemed to have deliberately forgotten how he saved her, or perhaps she was too embarrassed to mention it. "What kind of medicine is that? It's amazing!"

"My family's secret recipe will not be passed on to anyone else..."

As soon as the words came out of his mouth, Shen Yuan realized that the atmosphere was wrong. He was clearly feeling nervous when facing a strong enemy just now, but he was suddenly made to forget his current situation by the girl's friendly smile.

But soon.

The moment the sun rose, Shen Yuan and Butterfly Kanae saw a figure rushing towards them.

"elder sister!"

A girl who was much smaller than Kanae appeared in his sight. It was obviously Shinobu Kocho.

"I see. I understand..."

Shen Yuan looked up at the dawn sun and guessed the timeline he was in.

(ps: please give me flowers and votes!).

Chapter 16: Crazy training, reach level in seconds!

The timeline where Shen Yuan is located.

It was about four years before the main story began when Tanjiro's family was murdered.

That was the night before Kanae Kocho died.

However, judging from Douma's words, he should be being targeted by Muzan Kibutsuji.

And if he hadn't happened to meet Kanae Kocho, or if he had made a mistake in judgment and taken a slightly wrong step.

Then Butterfly Kanae is doomed to die.

Does this count as completing a hidden plot?

Shen Yuan seemed to be lost in thought.

You saved Chocho Kanae and defeated Upper Rank Two Douma, but your actions alerted Muzan Kibutsuji, and the enemies you'll encounter will be even stronger. However, you've decided to train with the Demon Slayer Corps for a while, honing your rank and upgrading your equipment before hunting the Demon King.

The system's simulator records Shen Yuan's status at all times.

Shen Yuan also checked the series of events he had caused from time to time. It was definitely a good thing that Kanae Kocho did not die, but his arrival would definitely produce some kind of butterfly effect.

So Shen Yuan decided to work hard to improve his strength before deciding on the next course of action.

He wants to achieve an S-level score.

Therefore, all decisions are made to make the ending of the story perfect.

......

The next morning.

Demon Slayer Corps, Butterfly House.

"Kanae, don't sleep anymore, take me to get the Nichirin Sword, how can you go back on your word!"

Shen Yuan appeared near the Butterfly House and shouted.

"Don't speak ill of my sister! You rude person!"

The petite Shinobu Kocho glared at Shen Yuan fiercely. Although she was only 14 years old, she had a very bad temper. When she heard Shen Yuan complaining about Kanae, she immediately protected her sister.

"... Turns out he's a sister complex."

Shen Yuan looked down at Shinobu Kocho from his superior position. He was about 1.8 meters tall, while the other party was only about 1.45 meters tall. Although she was still growing, she would stop at 1.5 meters at most.

"Humph! I saw you trying to do something bad yesterday while my sister was unconscious!"

The reason why the girl looked unhappy seemed to be because of some of Shen Yuan’s actions yesterday.

"You should thank me, otherwise if Kanae died from her injuries, wouldn't you cry to death? Of course, if you want to become the new owner of the Butterfly House, hehe."

Shen Yuan's slightly teasing words made the girl who was staring at him release strong hostility.

In the original work, Shinobu Kocho has a good temper because after attending Kanae's funeral, she always "smiles" in front of others, just like her sister did when she was alive.

Afterwards, Shinobu Kocho went through painstaking training and eventually became the Insect Pillar of the Demon Slayer Corps.

But all this is based on the pain she experienced when she lost her sister. Now that Kanae has been rescued by Shen Yuan, Shinobu Kocho is still that irritable tomboy.

After all, when she was a loli, Shinobu Kocho had a straightforward temper.

"Meeting is fate. I saved your sister. So you should call me your benefactor and apologize. You should know what to do when apologizing, right? Xiaonin, you don't want your sister to be bullied, right?"

Shen Yuan teased, his tone full of ill intentions.

Looking closely, Shinobu Kocho has short hair as if to show the difference from her sister. Although she is petite, her development is not inferior to her sister at all. The only difference is her personality is completely opposite.

"What's there to apologize for? I don't even know you!"

"You can't say that. Didn't you see me yesterday? So..."

at this time.

Just as Shen Yuan was about to say something, he caught a glimpse of a figure appearing at the door out of the corner of his eye.

"Ms. Kanae, you're awake. Did you have a good rest last night?"

Shen Yuan seemed like a different person. His tone changed from that of a ronin, a rogue, to that of a serious swordsman.

"Well...thanks to you."

Kocho Kanae responded softly, her eyes full of fatigue, as if she had not fully recovered yet.

"You're seriously injured this time. You need more rest. When you're better, take me to apply for a Sun Blade."

Shen Yuan's tone was calm, and his eyes were full of concern when he looked at Butterfly Kanae.

"Huh?" Shinobu Kocho widened her eyes and looked at Shen Yuan in disbelief.

She seemed to be somewhat surprised by his sudden serious attitude.

Why do I feel that this guy suddenly looks handsome?

No, it's an illusion!

This is not his nature, he must be lying to his sister!

Thinking of this, she quickly looked at Butterfly Kanae.

"Sister, this person said he wanted to bully you!"

Shinobu Kocho mustered up the courage to speak, her face flushed, obviously very nervous, but her tone was very firm: "But don't worry, I will follow you every step of the way, and I will never let this guy succeed!"

"Nin, Mr. Shen is a righteous man, how could he possibly bully me."

Butterfly Chanehui tilted her head slightly, then smiled and said, "Don't take it to heart, Shen Jun. My sister is just like that. She tends to say some nonsense. I will educate her in private later."

"Nothing, it's just that you two sisters have very different temperaments."
