Time to get back to work. He started digging and digging, ambient sounds animals and insects making are now natural noises to him.
He kept digging and from time to time, he emptied with his shovel the hole full of broken rocks and put them in his bags to clean the place up and go outside to put them there before he go back home.
He kept digging and digging, he looked at the hole and saw that he reached a less hard ground, a mud part. Looked at his watch and it was almost 5pm.
This means waters infiltrated the ground. From now on this would be easier to dig.
He kept digging and digging he looked at his watch and was almost 6pm.
Ambient noises around suddely shut. The cave became much more colder. His eyes started watering and his body reacting to something he himself didn't see was having goosebump.
From all these events he quickly packed his stuff and got out of the cave. Once outside, he took bags full of rocks and went back home wandering what made these things happen.
...
The next morning if off because he realised only the mud ground left. He does no more need the pick axe but only the shovel.
He got time to think about what happened yesterday and days before but he got nothing in mind but to say it was just my imagination because I was exhausted and being a whole day lonely in a large, dark cave my mind was playing on me tricks. What else could be?
After lunch he packed his stuff and headed to the cave. It's 1:20pm, he started digging with the shovel, removing mud of the hole, till the moment when he hit something. His ears and eyes were wide opened he hit a second time.
Instantly, without a noise, he saw a man next to him. His blood frozen. He stayed speechless. He couldn't say a word.
The mysterious man said: "who are you? what are you doing here?".
