It was a much more complicated formation than the one William just activated. And he knew just a single mistake was enough to ruin everything.
So he took his time to double check everything, reviewed everything in his mind, before starting to activate the formation.
The first step was to activate the grenades and then channel the resulting spirit power towards the other subsidiary formation. This was a step he did before, and so he didn't take much time in doing it.
Then it came down to the most important part. William guided the insane amount of spirit power and channelled it into spiral shaped paths. He made sure to do it this way so the gush of the spirit power wouldn't explode the toxin and ruin it.
Once the spirit power touched the barrels, a second wave of explosion occurred. This time it was much fiercer, and William already felt the pressure.
