The Golden Bird I

Hun!

"How long will this take," I said as I stood in the dark for more than an hour. Usually, the doors send you where you need to go, but very rarely, it makes you wait in the dark.

Some say it is one of the hidden tests of this place.

It had happened four times in the past two months, but I did not stay more than twenty minutes, and now it had been more than an hour, and I didn't know how long I would stay here.

I don't want to stay too long, especially not the eleven hours, which is the highest noted record of us humans. 

Another hour had passed, and I was still in the darkness, but now, I was not staying uselessly waiting. I am in my core working; in front of me is a large runic formation, a part of my Inheritance, I am looking at it from every angle, so I can find a way to optimize it efficiently.
