From Battle Through the Heavens Simulation to The Great Ruler

……

a few days later

Black Seal Restaurant, Room No. 1 (Top Tier).

Xiao Feng, who was cultivating with his eyes closed, suddenly opened his sword eyes and brought up his character attribute panel.

Under Xiao Feng's watchful gaze, the simulation countdown quickly reached zero, and the number of simulations changed from 0 to 1.

"Start simulation!"

With a silent thought in Xiao Feng's mind, the fifteenth simulation began.

"Ding! Randomly selecting a simulated world..."

Under Xiao Feng's expectant gaze, the text in the selection box changed wildly, and finally four big characters appeared: Demon Slayer!

"Ding! Please select simulation mode!"

[Text projection simulation (no cost)]

[Simulation of the main body projection (consuming seven million merit points)]

After this period of eliminating evil in dreams, Xiao Feng has accumulated more than seven million merit points, which is enough to carry out the simulation of his own body projection.

However, after some deliberation, Xiao Feng ultimately abandoned the idea of ​​using projection simulation.

After all, Demon Slayer's world level isn't that high, so the simulated rewards you can draw shouldn't be too expensive, probably not even exceeding one million merit points in total.

If Xiao Feng were to use the body projection simulation, it would be a waste of merit, so he chose the text projection simulation instead.

"Ding! Text projection simulation begins!"

Day 1: You find yourself transported to a remote, untouched mountain forest.

Before you could even figure out what was going on, you heard a terrifying bear roar coming from the forest not far away.

Your first instinct was to run, wanting to get as far away from the direction of the bear's roar as possible. However, you accidentally lost your footing and fell down the hillside, knocking yourself unconscious.

???

Xiao Feng frowned slightly. Was it really going to be this bad right from the start?

[Day 2: When you wake up groggily, you find yourself in a simple Japanese-style bedroom, and you discover that your leg is broken.]

Just as you were cursing God for being so cruel, a cute girl in a pink kimono walked into the bedroom carrying a steaming bowl of rice porridge.

The girl's name is Nezuko Kamado. It is said that when her brother went out to chop wood, he happened to find you with a broken leg and carried you back from the wilderness.

Upon learning that the girl's brother is named Kamado Tanjiro, you immediately realize that you have been transported to the world of Demon Slayer.

Thinking of the tragic fate of the Kamado family in the original anime, you plan to persuade them to move after your injuries heal, so as to avoid being targeted by Muzan Kibutsuji.

You originally planned to thank Tanjiro, your savior, in person, but you learned from Nezuko that her brother had gone to town to sell charcoal and wouldn't be back until evening, so you had to give up on that idea for now.

After drinking the rice porridge that Nezuko cooked herself, you felt warm all over and as if you had regained some strength.

Perhaps because of your physical injury and weakness, you fell into a deep sleep again shortly after regaining consciousness.

You were awakened by a commotion as night slowly fell.

To your utter bewilderment, Nezuko, dressed in a pink kimono, suddenly burst through the bedroom door and flew in, crashing heavily to the ground and falling into a coma, her fate unknown.

Just as you were about to climb over to check on Nezuko, a short-haired man with pale skin, bloodshot eyes, and wearing a black suit walked into the bedroom.

Upon seeing you, the wounded man, the short-haired man suddenly revealed a somewhat amused smile. His index finger shot out like a whip, piercing your forehead with lightning speed.

You feel as if something has been forcibly injected into your brain, and you gradually lose your senses. You feel incredibly hungry, as if your stomach is on fire.

"Holy crap! What kind of hellish start is this?"

Even though Xiao Feng knew that text simulation was a trap, he didn't expect it to be this bad.

I broke my leg on the first day of the game, and the big boss came knocking on my door on the second day. It couldn't be more tragic!

It's no exaggeration to say that Xiao Feng in this text simulation had the worst start of all the simulations.

[Day 3: After you finally manage to fill your stomach, driven by your instincts, you gradually regain your senses.]

You discover a fact that is hard to accept: apart from Nezuko, who has also been turned into a demon and is in a deep sleep, there is no one else in the house.

You felt your stomach acid churning and couldn't help but lie on the ground and dry heave, but nothing came out.

Your values ​​have collapsed. You can't accept what you've done. The thought of having to eat people to survive makes you feel like you'd rather die.

You rush outside like a madman, wanting to kill yourself with sunlight, only to find that it's snowing outside, and thick clouds block out the sun.

You didn't give up on the idea of ​​suicide. Rather than harming others later, you thought you could gamble on being able to travel back in time. You ran towards the sunlight in the distance.

Day 4: You sit on a huge, exposed rock, gazing at the rising sun on the horizon, quietly awaiting death.

When the warm sunlight falls on you, you immediately feel the pain of being burned by fire, and your body is engulfed in flames.

Just when you thought you could finally be free, your body, which had been melted by the sun, began to recover at a speed visible to the naked eye.

You are shocked to discover that you are immune to sunlight. Recalling that Nezuko and Tanjiro in the original work were also immune to sunlight after becoming demons, you can probably guess why you are immune to sunlight.

Perhaps, as the rumors suggest, the blue spider lily that Muzan Kibutsuji searched for over a thousand years to find was eaten as a snack by Tanjiro's family.

Therefore, when you consumed the corpses of Tanjiro's family while in a state of irrationality, you also absorbed the power of the blue spider lily contained in their flesh and blood, which is why you gained immunity to sunlight.

Unable to die, you cried and laughed, finally pointing to the sky with bloodshot eyes and swearing that you would personally send Muzan Kibutsuji to hell in this lifetime...

Day 18: After more than half a month of research, you find that you seem to have really evolved into a perfect creature. Not only do you have super regenerative abilities, but you are also not afraid of sunlight, do not need to eat people, and can even taste all kinds of food like an ordinary person.

During your wanderings, you encountered several cannibals that wreaked havoc in the area, and in the process of fighting them, you awakened the Blood Demon Art.

Your Blood Demon Art is called 'Demon Devourer,' which, as the name suggests, allows you to devour evil spirits and use them to strengthen yourself.

Because you know that Muzan Kibutsuji can see what other demons see before they die, you disguise yourself as a member of the Demon Slayer Corps every time you devour those cannibals to avoid arousing his suspicion.

The Demon Slayer Corps is an organization that specializes in hunting man-eating demons, and many man-eating demons die by their swords every year.

Furthermore, the cannibals you devoured were low-level cannibals, even weaker than Lower Moon demons. Even if Muzan Kibutsuji saw their memories before they died, he probably wouldn't care.

[Third month: After devouring dozens of low-level ogres, you find that your strength has increased significantly, and you should at least be no weaker than a Lower Moon demon.]

You've decided to start hunting the Twelve Demon Moons. You know you're no match for the Upper Rank Demons yet, so you plan to start with the Lower Rank Demons.

Based on the original storyline, you know that the Fifth Rank 5, who likes to play house, is hiding in Mount Natagumo, so you head there.

When I first met you, Lower Moon Five thought you were like other low-level cannibals, being chased by the Demon Slayer Corps and seeking his protection, which is why you fled here.

Therefore, Lower Moon Five proposed a deal: he would grant you greater power in exchange for you becoming his older brother.

Faced with Lower Moon Five's childish behavior, you feigned agreement and then launched a sneak attack when he was off guard.

Your strength was already comparable to that of the Lower Moon Five, and coupled with your unethical sneak attacks from behind, the Lower Moon Five quickly became nourishment for your growth.

Because Rui, the fifth Lower Moon, not only belonged to the Twelve Demon Moons but was also deeply loved by Muzan Kibutsuji, his memories before his death attracted Muzan Kibutsuji's attention when they were transmitted back.

Muzan Kibutsuji finally realized that you were not an ordinary demon slayer, but a traitor who had broken free of his control, and immediately issued a kill order against you.

[Sixth month: Ever since Muzan Kibutsuji issued a kill order to his cannibals, you have been relentlessly hunted down.]

However, you were not afraid of this; on the contrary, you were very happy. Who can refuse prey that comes to them willingly?

To avoid arousing Muzan Kibutsuji's suspicion, you deliberately suppressed most of your strength when you fought back against your pursuers.

In the memories transmitted back by those pursuers before their deaths, your strength was about the same as that of Lower Moon Five, leading Muzan Kibutsuji to believe that you were able to kill Lower Moon Five solely through a sneak attack.

Muzan Kibutsuji didn't realize that you were getting stronger by devouring those cannibals. He just thought you were very cunning, always choosing to run away before you noticed an Upper Moon demon approaching.

While being chased by cannibals, you also encountered members of the Demon Slayer Corps and even rescued a few of them.

[Eighth month: You unknowingly arrived at Mount Sagiri and encountered Tanjiro, who was training in the mountains.]

Tanjiro recognized you immediately and couldn't help but hurl a string of curses at you before swinging his sword at you.

The reason Tanjiro hates you so much is because when he returned home after selling charcoal, he found your scent mixed with the bloodstains left on his family members' bodies.

Tanjiro felt that if it weren't for him rescuing you and bringing you home, your family wouldn't have suffered such misfortune, and Nezuko wouldn't have become a demon. Therefore, he wished he could grind you to dust and also wished he could commit suicide to atone for his sins!

Faced with Tanjiro's attack, you did not choose to fight back, but let him vent his resentment until you were exhausted and could no longer swing your sword.

Seeing that Tanjiro was too exhausted to move, you sat down next to him and told him everything that had happened.

After learning that the culprit behind this tragedy was actually Muzan Kibutsuji, and that you even attempted suicide after regaining your sanity, the kind-hearted Tanjiro still chose to forgive you.

After figuring out the whole story, Sakonji Urokodaki, who had been hiding in the shadows, also emerged from the shadows.

In fact, Sakonji Urokodaki had already arrived. He was originally prepared to save Tanjiro, but when he found that Tanjiro had no intention of fighting back, he chose to remain still.

Based on what you just said, and considering that you saved several Demon Slayer Corps members more than two months ago, and that you heard other cannibals call you a traitor, Urokodaki Sakonji also believes that you are not lying.

Because you have evolved the ability to be immune to sunlight, if Muzan Kibutsuji finds out about this, he will definitely not spare no effort to devour you. Therefore, only one of you and Muzan Kibutsuji can survive.

Furthermore, the Demon Slayer Corps doesn't want you to be devoured by Muzan Kibutsuji, because then no one will ever be able to defeat him again.

Therefore, Urokodaki Sakonji decided to teach you the Water Breathing Technique, so that you could gain greater power, at least enough to protect yourself from Muzan Kibutsuji and avoid being easily devoured by him.

Chapter 130 Better to be a broken jade than a whole tile (Second update, please vote)

130.

[Year 1: After training with Urokodaki Sakonji for more than four months, you not only fully mastered the Water Breathing Technique, but also combined it with your own characteristics to develop the Water Breathing Technique to the Thirteenth Form.]

Based on the conditions for activating the Demon Slayer Mark in the original work, you adjusted your body temperature to above 39℃ and raised your heart rate to above 200, successfully activating the Demon Slayer Mark and further enhancing your strength.

Now that you possess strength comparable to an Upper Moon demon, and should be able to easily defeat Upper Moon Three, you've decided to begin hunting Upper Moon demons.

After bidding farewell to Tanjiro and the others, you went to Yoshiwara alone, deliberately concealing most of your strength, and narrowly defeated Daki and Gyutaro.

After receiving the memories of your death from Upper Moon Six, Muzan Kibutsuji became quite wary of you. He never expected that in just one year, you would have the strength to rival an Upper Moon demon.

Muzan Kibutsuji would never allow a cannibal like you, who grows so rapidly and has broken free from his control, to exist.
