The sun rose on the 3rd day. He knew that this quest would exhaust him. He packed his tools and added a shovel and some bags to clean the place up.

He looked at his watch, it was 6am. The sky was turning gray and cold as winter days were. A bit windy and rainy.

Arrived at the door, he went inside the cave. He was ready to start digging as fast as possible, because when he was in his day off he thought something must be there where rays of light point. 

No one would do this heavy rocky door for no purpose. And I have to figure out this quickly.

I started this out of fun but now I'm seriously looking at it. This couldn't be randomly done. That door someone had to put it there. And these rays of ligĥt are pointing to something I have to discover.

While he was thinking and digging he looked at his watch and it was nearly 9am. The cave was cold, drops of rain fell inside the cave from several tiny holes. 

Time go on and it was almost mid-day and he looked at the hole digged and was satisfied.

Lunch and rest time for several minutes.
