我的干劲像火一般在灵魂中燃烧。

My motivation started to burn like a fire in my soul.

注意到是身体在燃烧：，灵魂和身体，或灵魂和你的心。

And notice that it's the body that blazes: soul and body or soul and heart.

来吧，为了地上的爱和正义！把生命与灵魂完全投入！现在就燃烧起来吧，黄金的小宇宙！在这个黑暗的世界里，带来一线曙光！

Come on! Devote your lives and souls for the love and justice of the land! Burn the golden cosmo! Bring a ray of light to this dark world!
