With ten percent of Whis's ability, it is already possible to easily destroy a universe. Although, according to the data, the difference between Whis and Asahi's initial strength is not very significant.
But the further you go, the bigger the gap, and the last few digits were like insurmountable chasms.
Asahi had spent over five thousand years to obtain ten percent of Whis's power, and this was only achievable with the help of the Law Subsystem, otherwise, it might have taken several times longer.
At the moment, Asahi is quite satisfied, as he can use all Whis's ability, but only to the extent of ten percent, including the ability to manipulate time.
Regarding the laws, he had an advantage because of the assistance from the subsystem.
If he completely mastered all of Whis's ability, he would be able to surpass Whis significantly in terms of Laws. Unfortunately, he hadn't reached fifty percent yet, otherwise, he might even get Whis's staff, which is a splendid artifact.
But for now, Asahi is already very satisfied.
"Wait a minute, I've been in seclusion for over five thousand years, and almost three years have passed on the outside world. The plot of the Demon Slayer will not be already concluded, right!"
Suddenly, Asahi realized a big problem, what if Tanjiro had already been possessed by Muzan?
In such cases, there should be only three possible outcomes.
Either Tanjiro, with the help of his allies, forced Muzan out. Or Tanjiro temporarily suppressed Muzan but was ultimately killed by others.
The third possibility was that Tanjiro couldn't completely suppress Muzan, which could lead to two minor endings: either Tanjiro killed everyone and left, or regained some consciousness and chose to depart on his own.
Regardless of which outcome had occurred, Asahi didn't care now, as he felt like he had missed something.
Of course, he couldn't be sure at which point in the Demon Slayer's storyline he was entering. If it began after the events on Tanjiro's family, then there were still many years before the plot began. That's why he thought it would be worth checking.
"It's such a waste. Not participating in this world somehow feels like something is missing. But it would be best if Muzan is dead!"
Asahi had nothing but disdain for Muzan, and he wished for Muzan's complete destruction. He recalled that the Demon Slayer manga had been a tearjerker for him, and he had wished to grind Muzan into powder.
Now, it would be best if Muzan was dead, otherwise, Asahi would love to play with him slowly.
Without further ado, he entered the Demon Slayer World. As for the channel, he thought it was better to leave it sealed.
Although the chance of Muzan coming to this world was minimal, and the portal was located in the Black Bullet World, so it didn't pose any significant threats, but there is no need to unseal it directly.
After entering the Demon Slayer World, Asahi covered the entire world with his perception and find out the current timeline.
"I see… Tanjiro is still on Mount Sagiri, which means that the plot hasn't progressed too far yet!"
Asahi took a step forward and arrived at Mount Sagiri at the next moment, as he intended to train Tanjiro well.
Compared to overpowering the world by himself, he thought it would be better to nurture Tanjiro instead. While he could easily eliminate all demons by eliminating Muzan, he felt that this would be too easy for Muzan.
Even though Tanjiro had already been blessed with incredible abilities in the original work, Asahi didn't mind helping him get even stronger.
Asahi directly covered himself with a black robe, concealing his human appearance completely. He appeared as a mysterious figure hidden in the darkness. And his goal was to manipulate the world from behind the scenes.
When he came to Mount Sagiri, Tanjiro was currently engaged in a battle with Sabito. Judging by the current situation, it seemed like there was still about half a year before the events of the main plot began, as it took half a year to defeat Sabito and cut the largest boulder.
"Get up! What are you doing? With your current strength, you might as well give up!"
At this moment, Sabito is reprimanding Tanjiro fiercely. He is doing this for Tanjiro's own good, because Hand Demon is not easy opponent.
In the original work, Sabito single-handedly wiped out almost all the demons on Mount Fujikasane before facing off against Hand Demon. Hand Demon was smart enough to avoid Sabito at first, knowing he wasn't a match. Hand Demon only attacked Sabito when he was already exhausted, eventually defeating him.
Sabito's constant attacks on Tanjiro were aimed at making him stronger and preventing him from being killed outright.
In this world, souls were unique, and when people died, they would choose to protect their companions and loved ones. As a result, their souls would not dissipate, only disappearing once their unfinished business or lingering attachments were resolved.
"Come again!"
Tanjiro is also an incredibly resilient individual who never gave up easily. His determination was unwavering, and even if his will faltered, he would self-hypnotize to prevent himself from giving up.
It was safe to say that he is an undefeatable force. He could be beaten down repeatedly and would still stand up, displaying incredible willpower.
"Are you worried?"
While Sabito was locked in combat with Tanjiro, Makomo stood nearby, observing the fight. However, during this observation, a voice suddenly reached her ears.
In an instant, Makomo was taken aback, and looked at her side in astonishment. She then saw an existence completely covered in black robe, making it difficult to discern whether it was a person or something else entirely. In shock, Sakonji is shocked.
"Who are you? And why can you see us?"
Makomo is puzzled. After all, they are already dead, and if they wanted someone to see them, they had to intentionally manifest themselves based on their lingering attachments, otherwise, there will be no difference between being dead and alive.
After their deaths, they had returned to this place, and among all the souls here, the two of them were the strongest and could manifest themselves, that's why Sabito appeared in front of Tanjiro and trained Tanjiro.
The others are basically just remnants of souls, they're just stubborn obsession, and almost unconscious. Compared with these two with intact souls, there is a huge gap.
But now, this existence actually saw them, which is very abnormal.
"Are you puzzled? You are obviously dead, but I can see you!"
Instead of answering Makomo's question, Asahi posed another question.
"You know we are dead? Who on earth are you?"
Makomo's expression grew even more serious this time. After all, this mysterious presence is too unsettling.
