MTL - I Refused to Be a Substitute, and Shot to Fame on a Variety Show With My Mother-In-Law - Chapter 557 farewell, never see you again

I finally managed to kill the demon lord.

The “S-rank Hero Factory” that raised 1,000 S-rank heroes.

The graduates’ manufacturing machine.

The strongest support.

These are all words that refer to me. But could this actually be the world of that game?

This is the story of a super soldier! This is the story of a super soldier!

The previous life is nothing but a joke. Being used completely then abandoned mercilessly. How can I be this stupid to not even notice such an obvious scam? Fortunately, I can have a second chance with my rebirth. Sister, Brother Yi and whoever mistreated me in my previous life, are you ready for my revenge and the counterattack of a princess?
