New techniques!

When Rui entered, he immediately headed over to the grappling wing of the defense-oriented section of the library. He intended to first and foremost strengthen his grappling and full-contact combat. There were a vast variety of techniques in there, but unfortunately, most of them were not free of cost.

Throws and flips of different forms and principles.

Locks and holds of different kinds and based on different mechanism.

A variety of takedown and rolling techniques as well.

Just browsing through them evoked a strong sense of greed within him. It almost clouded his judgement, but thankfully the prohibitive cost prevented him from acting on his greed.

"I firstly need a flexible technique that allows me to ensure I won't be defeated too easily in full-contact grappling." He muttered to himself. "This will serve as my defensive foundation in so far as grappling is concerned, if someone ever successfully executes a takedown on me, I won't be helpless."
