The Conversion Technique.

Fifteen minutes later...

"So, what do you think?" Felix asked with an easy-going smile while staring at his teammates lying on the floor with deadpan expressions.

Only Noah and Sylvia were standing next to him with disappointed looks.

"You..You are a monster..."

"Captain, you must be a masochist to handle such a pain every two days..."

"I am starting to reconsider using a mythical bloodline..."

Olivia and the rest gave Felix a look meant for monsters, not expecting that the pain would be this agonizing.

No one even attempted 13% like Felix mentioned. Instead, they started with 10% like they were used to.

Yet, not a single one of them managed to survive for a single minute!

The instant they give in to the pain and fainted, it was all over for them.

Realizing that they needed to go through this hell for fifteen minutes made them understand how laughable their previous integration compared to this.
