Trouble

The strength flowed within him like a tsunami, threatening to burst out with the slight exertion of the muscles. 

If it weren't for his absolute body control, he would definitely have struggled to keep his strength under wrap. 

The only thing running through his mind was what if he activated one-fold strength technique to the power he currently has. 

Or even Two-Fold strength, doesn't that mean he could literally crush everyone and everything blocking his path? 

David thought the idea was a feasible one and after some thoughts he decided to try it.

Revolving his blood, he activated the strengthening technique and after a while, nothing seem to be happening.

David frowned slightly. "It didn't work?" he had used the strengthening technique for quite some time now. 

He was more familiar with the technique than he had been with other ones which was why he was confident he wouldn't make any mistakes in activating it.
