realizing the changes

All that took place earlier was a lot to take for someone from the modern Earth. It took a while for Sam to calm down and come to a compromise with the situation. He didn't get close to the platform but started searching the premises. 

The last message sent by the sword was like a joke to him. After being controlled like a puppet, he was determined to keep a certain distance between him and the sword.

" I need to find out where I am first and what happened, this seems to be a big cave, then where is the entrance, I will look around"

After half an hour of looking around he came to the conclusion that there was no entrance and possibly this was no cave, but an air pocket inside the earth or inside a mountain.

" Is it possible that this is heaven or hell and I am going through some test or something...

No use thinking too much I will wait and see. The problem is air, food and water."

...

After one day... Sam came to the conclusion, this was neither heaven or hell and he was very much alive... As for the cave being created by some immortal being this was very much possible, but he didn't find any restrictions or force fields restricting him from doing anything. 

Other than the one he faced when trying to free the Evil sword.

So he decided to go with the theory that this must be an immortal cave created by some immortal being and the golden brown liquid must be something that got collected due to some formation that was collecting natural energy from the surrounding or a naturally formed place with thick spiritual energy....

"Most probably I have fallen through an air hole in the mountain range, which was exposed due to the force of the lightning strike, and after falling I probably reached this place, but the hole got filled up again... And I am still alive because of this supernatural environment..."

The most astonishing thing he found out was about himself. 

His body has become strong to an unknown level, his full powered punches could destroy big boulders..…

  Toughness of his body has increased to a level that he could detonate a grenade by holding it in his hand.…

Most surprising was his brain, his IQ has increased spontaneously, his calculation abilities have become much faster. 

He also had a feeling of epiphany all of a sudden, he started relating all the knowledge that he has ever collected and coming out with new conclusions and conjectures...

His five senses have improved its perception level a hundred times or maybe more.

When his super sense and faster brain was combined he could notice even the minute of changes happening all around him, it was like he was some unknown beast with a very keen perception.

Another Amazing thing was that he had also developed a new sense, like a sixth sense or a spiritual sense, through which he can observe everything around without relying on the other five senses.

With the help of the epiphany, he came to a conclusion that this was through the vibration state of the surrounding and he was able to somehow perceive this vibration, it was like seeing and knowing without looking.

He also noticed that he was not hungry or thirsty anymore and his body was absorbing energy from the surrounding automatically little by little. |

But the energy absorbed from the earth through his feet was much more compared to that which was absorbed from the surrounding.

This energy was also nourishing and strengthening his body minute by minute. 

He also got the feeling that he didn't need to breathe to stay alive. He could absorb the energy to stay alive.

With the problem of food, water and air solved. 

He became more relaxed and started taking things more slowly and thoroughly, he was taking even the minute details into consideration.

....

Fifteen more days passed by, and now a young man could be seen sitting in lotus position and meditating, there was a golden brown color aura surrounding him...

He opened his eyes, he was born with brown eyes, but now they had a golden tint to it, but instead of giving an aggressive air like the brown eyes of a tiger, it was giving out a calm and composed feeling.

After 15 days of searching and contemplation, he came to the conclusion that this immortal cave had high affinity to earth and the liquid essence was related to earth as he could feel a solid connection with the earth after absorbing the essence.

He also found out that he could know what is happening around him in a 10 meter radius if he closed his eyes and concentrated on using his spiritual sense. 

It was as if he had a heat detection, but more in a transparent mode such as an x ray scan.

At the same time he also found out that if he used his spiritual sense on earth it reached about 60 meters.
