[Year One: After training with Urokodaki Sakonji for over four months, you not only fully mastered the Water Breathing technique but also adapted it to suit your characteristics, advancing it to the Thirteenth Form.
By referencing the conditions in the original story for activating the Demon Slayer Mark, you raised your body temperature to over 39°C and your heart rate to over 200, successfully activating the mark and further enhancing your power.
At this point, you now possess strength comparable to the Upper Moons and should be able to trounce Upper Moon Three. You decide to start hunting the Upper Moons.
After bidding farewell to Tanjiro and the others, you head alone to the Yoshiwara Red-Light District. Hiding most of your strength, you narrowly defeat Daki and Gyutaro, devouring them afterwards.
Upon receiving the death memories transmitted by Upper Moon Six, Muzan Kibutsuji grows increasingly wary of you. He didn't expect that after only a year, you would have gained the power to rival the Upper Moons.
Muzan cannot allow a demon like you, who proliferates and is beyond his control, to exist.
Thus, Muzan immediately orders Nakime to teleport Hantengu, Gyokko, and Douma—who are closest to you—to your location, commanding them to kill you together.
Initially, Muzan thought you were doomed this time, but what he didn't anticipate was that after devouring Upper Moon Six, your strength had increased even further. You comprehended the Transparent World and Red Nichirin Blade and reversed the situation by defeating and devouring Douma and the others.
While Muzan hesitated, wondering whether to avoid confronting you directly, he saw through Douma's death memories that you were openly basking in sunlight without any harm.
Realising you had evolved to become immune to sunlight, Muzan immediately discarded all his reservations and resolved to devour you at any cost.
In the end, Muzan used Kokushibo and Akaza as bait, and as you defeated and devoured them, he used Nakime's abilities to teleport you into the Infinity Castle.
Though you fell for Muzan's trap, you remained utterly unfazed.
After all, both you and Muzan sought to devour each other, so it ultimately came down to strength.
However, you both underestimated each other's power. Neither of you was able to devour the other entirely, and instead, you merged into one being, with both of your souls remaining intact.
To put it simply, you became a dual-souled entity sharing one body with differing thoughts, akin to a split personality.
Although Muzan wasn't able to entirely devour you, he was pretty content, as he had acquired the ability to be immune to sunlight and could now enjoy the taste of food like an average human.
Just as Muzan revelled in the idea that he had finally become the perfect being, you seized control of your body and headed to the nearest active volcano.
Amid Muzan's threats, pleas, and curses, you resolutely leapt into the boiling lava.]
You died!
"Well done! Better to be broken jade than intact tile; that's exactly like me!"
Seeing that his simulated self had chosen to perish together with Muzan rather than live in disgrace, Xiao Feng couldn't help but slap his thigh in excitement.
[Simulation complete!]
[Now, drawing simulation rewards, please purchase any desired rewards before randomly selecting one.]
[Perfect Demon King Bloodline (Price: 1,000,000 Merit Points)][Kokushibo's Transparent World Experience (Price: 30,000 Merit Points)][Douma's Ice Blood Demon Art (Price: 10,000 Merit Points)][Akaza's Cloak (Price: 1 Merit Point)][Hantengu's Clones' Blood Demon Art (Price: 50,000 Merit Points)][Urokodaki Sakonji's Water Breathing Experience (Price: 2,000 Merit Points)][A Nichirin Blade (Price: 10 Merit Points)][A Bowl of Tonkotsu Ramen (Price: 1 Merit Point)][A Golden Folding Fan (Price: 1 Merit Point)][A Pair of the Oiran's High Heels (Price: 1 Merit Point)]
Xiao Feng was overjoyed and immediately spent over 90,000 Merit Points to purchase nine of the relatively cheaper simulation rewards. Then, using his free lottery chance, he won the [Perfect Demon King Bloodline] worth a million Merit Points.
"Use it!"
As soon as Xiao Feng willed it, the blood-red sphere representing the [Perfect Demon King Bloodline] turned into a streak of red light and merged into his body.
Sensing the invader, the Dou Emperor Bloodline within Xiao Feng surged and began devouring and refining the Demon King Bloodline.
Once the Demon King Bloodline had been wholly consumed, Xiao Feng's cultivation increased as his bloodline power strengthened, breaking through from Seven-Star Dou King to Eight-Star Dou King.
In addition to the increase in cultivation, Xiao Feng could feel that the [Emperor's Giant] within him had also grown stronger. When he transformed into the Flame Giant, he could now unleash power comparable to a Nine-Star Dou Ancestor.
Although the Demon King Bloodline had been devoured, many of its benefits were retained by the mutated Dou Emperor Bloodline.
For example, Xiao Feng could now, like Muzan Kibutsuji, forcibly turn others into demons by injecting his blood into them.
Because the Demon King Bloodline Xiao Feng obtained was from the simulation where he had merged with Muzan, any demons he turned would also be immune to sunlight and able to taste food like an average person.
Gulp!
After adjusting to his increased cultivation, a flash of light appeared in Xiao Feng's eyes, and he took out a Dou Spirit Pill, swallowing it.
Rumble...
The Dou Spirit Pill instantly melted, turning into pure, vast energy that exploded within Xiao Feng's body.
Xiao Feng quickly activated the Nine Transformations of the Swirling Dragon technique and began devouring and refining the energy.
After over an hour, Xiao Feng finally refined all the energy from the Dou Spirit Pill, and his cultivation broke through to Nine-Star Dou King.
"Awesome!!"
Feeling the several-fold increase in his Dou Qi, Xiao Feng couldn't suppress a smile.
After calming himself down, Xiao Feng turned his attention to the [Kokushibo's Transparent World Experience] skill orb.
In Demon Slayer, [Transparent World] is an incredibly special realm that requires extreme effort and struggle to reach.
Those who master [Transparent World] can focus and shut down unnecessary senses, allowing them to see others' bodies as if they were transparent.
Simply put, [Transparent World] is similar to the Byakugan from Naruto, not only allowing you to see the Dou Qi and blood flow within your target but also greatly enhancing your reaction speed.
