Changing Mood

"Come to me and rest," I said to Nero as he came out of the tunnel; taking only a third of the time than we did.

This time, he had listened, and a few minutes later; I opened the door and let him in. 

"You have worked hard," I said as I took him in my arms.

He snuggled for a moment, before going back inside the core and a few seconds later, he was asleep. 

A minute after that, his body begin to shine gently as he started to make a breakthrough.

Ashlyn and his breakthroughs are far simpler than mine. They only need to sleep, and they would make a breakthrough.

There is no danger of dying or anything.

I look at Nero for a couple of seconds more, before turning to loads and loads of stuff he had brought. On the way, he killed many things and found a few things; all of which he unloaded before sleeping.
