Heart
Sam started observing the surroundings and after finding out of the area where the energy waves are higher than normal, Sam moved in that direction.
Mia slowly followed him along. This process continued for half-an-hour. But when they reached the place with the most energy concentration, there is nothing they could see. This made Sam frown, and he extended his hand as he touched the floor. Even without his spiritual sense and observation, Sam could feel the energy here.
It is too thick to be unnoticed.
When he placed the hand on the floor and started observing, Sam found that there is some sort of energy manipulation here.
So, he started examining the area and he finally found the traces of formation. There is something that is hiding within the Sea bed and a formation is made to hide it. Sam doesn't know if this is a dangerous thing to open.
