Song of Adolescence - Chapter 387 Ascending the Tower, Spirit Wandering

Fate is weird. Of all the people in the world, why would it select me to send to a different world?

And what is it trying to do? Put up a show by giving me a system? But oh well, what do I care.

The previous owner of this body was a cripple and looked down on, but now I can slap their faces with my system.

Young masters? Get out of my way!

Princes? Geniuses? Oh please. I have a system. That does not mean anything to me.

I know that I am not the greatest. But fate gave me a cheat system, and I am not wasting it.

I am going to do whatever it takes to conquer this world. Fate forced me to do this. It isn’t my fault if I cause some ruin on the way.

While the blue light blossoms, the insignificant struggle at the bottom. He grasps the opportunity to change his fate and embarks on an unprecedented path…

Reborn as Red Army Misha!
