The OP Technique

I gave the order out loud and thought about it in my mind. I kept watching in anticipation. Would they execute what I just said? Would they move against their will and smash these weapons?

Would their shadows be this mighty existence, enough to control the real bodies? Or what?

I really wanted this attack to link. If so then it would be just OP technique, one that I'd simply keep using from now on.

The next moment I felt strange things inside my body. Up till now, that heat from before was still raging at my body.

But when I gave such an order, it felt like this heat was dying down at a fast pace. I closed my eyes for a brief second and there I saw my spiritual energy getting pushed out, drained fast like it was getting dried up.

Damn! That technique was really working, but it required such a ton of energy to get executed.

If this continued, then my energy wouldn't be enough to sustain it for more than a few minutes. Besides, I was still letting my threads control more humans.
