Simultaneous time travel: But our system is out of sync!

Demon Slayer: World of Demons.

As the snow fell heavily, Tanjiro, carrying a basket on his back, walked step by step towards his home in the mountains after returning from selling charcoal in town.

Although the knee-deep snow and the biting wind made every step difficult for him, he thought of his mother's warm hands; his obedient son, Mi Douzi; his mischievous and adorable younger siblings; and Lin Bei, who taught him to read and write and promised to take him to see the outside world.

Tanjiro felt that his physical fatigue was no longer a problem, and his steps became lighter.

However, as he happily climbed up another steep slope...

A faint smell of blood drifted into his unusually sensitive nose on the wind blowing in his face.

"The taste of blood!"

At that moment, Tanjiro suddenly remembered what the old man who had asked him to stay the night before had said.

After the sun sets, man-eating demons will roam around, killing and harming people.

Only demon hunters can rival them.

A bad feeling crept into Tanjiro's heart.

"Could it be?"

"impossible!"

"Absolutely not!"

Tanjiro quickened his pace again, running anxiously towards home.

However, when he ran back to his doorstep, he saw a scene that made his eyes widen in horror.

The white snow was stained red with blood.

Corpses were piled on top of each other, lying in pools of blood.

"Clatter—"

Dropping the basket on his back, Tanjiro practically tumbled and crawled to the corpse.

He knelt on the ground, looking at Lin Bei's blood-stained corpse and the girl protecting it, his hands trembling, his eyes filled with disbelief.

"Lin Bei!"

"Beans!"

"What's wrong?"

"What happened?"

"What happened...?"

However, when he turned his head, he saw a scene that made his heart stop.

The once simple but cozy little home is now a mess.

The gentle mother lay on the ground with half her neck torn open, holding her younger sister Hanako, whose body had been ripped in two, in her arms.

Blood stained the ground and walls, and also the bodies of his younger siblings.

"Mom, Hanako."

"Takeo, Shigeru."

"Nie Douzi, Liu Tai."

"Lin Bei".

Tanjiro suddenly felt everything go black, and he felt as if the whole world was collapsing.

However, at that moment, he suddenly heard a faint panting sound.

The collapsing world paused, and Tanjiro rushed to Nezuko's body.

A moment later, his face lit up with delight, and he picked up the beans and ran down the mountain.

However, just as Tanjiro's figure was swallowed by the wind and snow, Lin Bei's lifeless body, which had been lying on the ground, suddenly sat up.

"Cough cough cough—"

After a violent coughing fit, Lin Bei finally coughed up the blood clot that had been stuck in his throat.

"Pooh--"

After spitting out blood clots, Lin Bei finally had the strength to stand up again.

However, when he stood up and looked at the corpses scattered on the ground, a flame of revenge rose in his eyes.

"Muzan, I crawled back alive from hell."

When Lin Beigang transmigrated to the Demon Slayer world, he was penniless, had no identity, and was several years younger.

Most importantly, he lost his memories of his past life and lived in a daze all day long.

Fortunately, he was adopted by Tanjiro's family and survived.

It wasn't until yesterday, when Tanjiro went to town to sell coal and didn't return home that he finally understood the mystery of his reincarnation and regained his memories of his past life.

The moment Lin Bei regained his memories, he prepared to run away with Tanjiro's family.

After all, according to the plot, Muzan is going to kill Tanjiro's family tonight.

However, when he tried to escape with Tanjiro's family, he found it was too late.

Muzan, with his black hair and black clothes, was already blocking the doorway of the house.

Despite his best efforts to save the family.

For an ordinary person like him to fight against Muzan is like an ant trying to shake a tree.

The final result was that Lin Bei and Tanjiro's entire family were killed by Muzan.

Just before his death, he was pulled into the shared space and given a cheat code, thus avoiding death.

However, at this moment, Lin Bei felt his weak heartbeat and almost no breathing, and there was no joy or surprise in his eyes as if he had survived a disaster.

At this moment, he was neither truly alive nor truly dead.

It was neither a living person nor a ghost like the Bean.

Besides the system's cheat-like ability, the reason for all this was that he was also tainted with Muzan's blood.

Thinking of this, the flames of revenge in Lin Bei's eyes burned even brighter, and he wished he could kill Muzan immediately.

He felt the faint connection created by the trace of Muzan's blood that had merged into his body, his voice soft yet unforgettable.

"Muzan!"

"You wait for me!"

"I will definitely take your dog's life to avenge everyone."

But Lin Bei quickly calmed down.

Firstly, Lin Bei knew that with his current strength, going to Muzan would be like a lamb entering a tiger's den.

Secondly, he woke up too late; Tanjiro had already carried Nezuko, who was about to become a murderer, down the mountain.

Tanjiro and Nezuko are in great danger at this moment.

If anything goes wrong, Nezuko might not regain consciousness and kill Tanjiro.

Nezuko will be mistaken for a demon and eliminated by the passing demon hunter Giyu Tomioka.

Therefore, the most urgent task is to catch up with Tanjiro and Nezuko as soon as possible and protect their safety.

So when Lin Bei woke up, he didn't care about anything else and got up to follow the footprints that hadn't yet been buried by the wind and snow.

However, after running only a few steps, Lin Bei noticed something was wrong.

He noticed that he seemed to have become lighter.

No, a more accurate statement is that he became faster.

My body, which used to be heavy and sluggish, is now unusually light, so much so that running on knee-deep snow feels like walking on flat ground.

Even the strong wind blowing in his face, mixed with snowflakes, did not make him feel cold.

It was as if his body could no longer sense changes in temperature.

Lin Bei knew that all of this stemmed from his current special state.

Although he was a living dead, he was spared the fate of being turned into a demon by Muzan's blood.

However, it also resulted in the loss of some perception of the outside world.

Lin Bei even had a vague feeling that losing the ability to perceive temperature was just the beginning.

As time goes by, he will gradually lose other senses.

Once he loses all his senses, he will die completely, without even the chance to become a ghost.

However, faced with this almost hopeless future, Lin Bei's mind remained calm and undisturbed.

At that moment, he had only two thoughts.

One of them is to protect Tanjiro and Nezuko.

The second is to find and kill Muzan.

Nothing else matters.

As for life and death, he had already disregarded them at this moment.

While Lin Bei was chasing Tanjiro and Nezuko, Tanjiro had already carried Nezuko halfway up the mountain.

He had already exhausted most of his strength when he went up the mountain, and now, carrying the beans, he was almost completely worn out.

His breathing was rapid and heavy, each breath feeling like a knife slicing through his lungs and trachea.

The ground beneath his feet was heavy; the soft, thick snow felt like a series of nooses, making it difficult for him to move.

But he dared not stop, nor could he stop.

Among all the family members' remains, Tanjiro discovered that only Nezuko still had warmth.

So whenever Tanjiro felt his feet were about to give way and he could barely take another step, he would encourage himself.

"Come on, Tanjiro!"

"Midouzi is not dead yet. Her body is still warm. As long as we can find a doctor in town after we go down the mountain, Midouzi can still be saved."

Tanjiro, focused on descending the mountain, didn't notice that Nezuko, whom he was carrying on his back, slowly opened her eyes.

But at this moment, the kindness and innocence that had been in her eyes were gone.

All that remained were reddened eyes and a terrifying gaze fixed on Tanjiro as if he were a prey.
