Capítulo 407: Not enough!

I took a deep breath... and activated all five layers of formations at once. 

At first, nothing much happened. 

The energy contained within the monsters' remains wasn't something that could be extracted easily. And so, for the first few minutes, I actually sat down and did nothing, waiting for the chaos within the formation to grow sufficiently enough. 

Soon enough, the blood of the monsters started to decompose, letting out all the mana within out. 

Normally, this mana would simply escape and be absorbed into the greater flow of energy that formed the worldwide flow of mana that most cultivators used to grow. 

It was also the source of the energy that my outermost formation pulled in to then kickstart the entire process.
