How could this happen?
Su Chen was undoubtedly shocked to his core.
Because just now, he had suddenly felt the blood in his body stir.
It was the presence of one of his own kind.
And Su Chen had obtained his blood from Muzan.
In other words, what Su Chen sensed now was a demon's presence.
And this presence was immensely powerful.
The identity was easy to guess, because only three demons remained now.
Doma, Kokushibo, and Muzan.
Su Chen knew how powerful Doma and Kokushibo were, and neither could possibly possess power on this level.
Doma was nowhere close.
Kokushibo fell just short.
Su Chen had fought Kokushibo last time, so he had some idea of his strength.
He was very powerful, almost equal to Su Chen before he had mastered Light Breathing, but Su Chen had still been half-human back then, after all.
So he had fallen somewhat short in endurance.
Then, after ruling out all the correct options, the answer was almost obvious.
Muzan!
Muzan had come to the Demon Slayer Corps' base.
This was Muzan's unique presence.
A savage presence belonging to a demon alone.
Dark, sinister, and cunning!
The look in Su Chen's eyes was icy.
How could this happen?
Su Chen could not understand it.
By all rights, Muzan's invasion should still have been some time away.
At the very least, Hashira Training should have been nearing its end.
Right now, the three youngsters had not even begun their training, and Tanjiro seemed to be injured too.
So the timeline did not match up at all.
Besides, with Tokito here with him, Nakime should not have been able to discover the Demon Slayer Corps, either, right?
And it was even in that direction.
Could his arrival have caused a butterfly effect, bringing everything forward?
