A certain knot in Sanemi Shinazugawa's heart seemed to loosen just a little.
He sat silently beside the campfire and said nothing more.
Yan Zi and Kazami, however, were more interested in the method Xia Xi had mentioned for escaping a demon's control.
It was something almost any normal member of the Demon Slayer Corps would be curious about.
And after Xia Xi saw that Shinazugawa's emotions had settled down,
he began discussing it with Street Girl and his nominal master with considerable interest.
As far as the Dawn Hashira was concerned,
Muzan's ability to remotely influence all demons through demon blood, interfering with them and killing them in real time,
looked, no matter how he considered it, like remote control through some special signal.
The Demon King was like the main router.
He was the central node with the highest privileges.
And all the demons scattered across the Far East who had received demon blood were connected to his network.
As for the process by which he turned people into demons,
it involved forcibly injecting [virus] demon blood containing firmware and drivers into a normal human's body.
That human was then assumed to have agreed to connect to the main router.
Through this network, Muzan could also check every demon's location and assign them different privileges.
Take the Upper Ranks, for instance.
Their privileges were clearly different from those of ordinary demons.
Every demon who had tried to recruit Xia Xi had used much the same pitch.
An Upper Rank had to agree before Xia Xi could be turned into a demon.
Moreover, the control commands the Demon King could issue through this network were not limited to checking his subordinates' online status and coordinates.
Xia Xi alone knew of several.
For example, directly sending [communication] to all demons.
