The Story

Bernhard wondered if I could grow any bigger. As I was thinking that, I heard this voice from the god of war:

I hear you want to become a demigod, hmmmm. If you want, I'll show you how powerful you can become.
I answer: I don't know if it's a good idea. Without warning, I start to grow and cling to the skyscraper, realizing I have barely any control over my body. Kronos notices my inner struggle and runs to me, calling in my ear. Show me your call, don't fight it. Bernhard called to Kronos: Wait, this could be a bit dangerous.

I say to Kronos: I don't want to spread fear among the people. Kronos, understand, and tell me: let go. Why should I die? Kronos chuckles: you're already too big and points to the ground.

I stand up and realize that I am already so huge that I am taller than the biggest skyscraper in the city and realize that Kronos is still a bit small.
Kronos noticed this too and began to grow, and he told me: The gods won't leave you alone; after all, I'm your right hand, and he sits on my upper arm and strokes me.

Hmmmm, is there perhaps a way for Bernhard to improve his large size as well? The God of War answers me: It depends on his will, but he decides based on his survival power. But I can still change that.
