I Wanted to Lie Flat from the Start, but Ended Up the Strongest Freeloader Divine Beast

I was reborn on a continent where beast taming was everything, as the lowest-grade contract beast. At the same time, I bound myself to an utterly ordinary lie-flat System.

In my previous life, I was a corporate drone stuck at the very bottom of society. I worked hard all my life, only to die suddenly from overwork. So this time, I've chosen to lie flat.

While the other contract beasts pursue offense, I'll pile everything into defense, then add some counter-damage skills and magic treasures. I'll lie still and let you hit me. After all, there's a saying:

Outer circle shreds, inner circle burns; Black Cleaver and Liandry's reduce both resistances. Sunfire, Thornmail, and Liandry's: hitting me is the same as hitting yourself.

This time, I'm lying flat.
