The only people capable of using an attack Okkotsu couldn't even detect were Gojo-sensei and, if he had to name anyone else, Lin Mu.
So the moment he saw Lin Mu, Okkotsu immediately guessed that Lin Mu had been behind the attack just now.

Those rules would not affect their original plan, so they had
