At the sight of that dark red blade, Muzan Kibutsuji's pupils instantly contracted into dangerously sharp pinpoints!
Yoriichi Tsugikuni was here!
Muzan Kibutsuji's five brains frantically began reviewing his actions.
After Hantengu's death, he had ordered Nakime to use her Blood Demon Art to create large numbers of eyeballs and station them densely around the area where Hantengu had died, naturally to find out exactly what Hantengu had encountered before his death.

In other words, as long as he could monitor Tamayo's movements, he could indirectly keep track of Yoriichi Tsugikuni's movements!
Especially after obtaining the "Blue Spider Lily," Muzan Kibutsuji had been all the more glad that
