"If it can affect my blood flow. Then it should probably be a treasure with affinities related to blood!" His brain lit up as he exclaimed. He swiftly closed his eyes and took a deep breath to switch his focus on his surroundings.
At the same time as his senses were expending outwardly to their utmost. He fiercely retracted it and focused all of his senses to his body. He then proceeded to focus it on a single blood cell.
Pop! He heard the sound of a bubble popping in his mind, and his vision was troubled for a short period. His view was rendered black for a few seconds; Then, a blinding light flashed in his mind chasing away the darkness.
This act of his had completely changed what his eyes saw. The walls and objects present around him were darkened, but he could still precisely pinpoint any object in the room. It was just that his senses were focused on something else. To be more precise, his eyes were neglecting the majority of the items and construct in his surroundings; But his sensitivity to blood was sharpened to a terrifying degree.
In this special state, Fell's sight was completely different. All around him; blood bubbles appeared, those were all the individuals that were currently present in his apartment's building. He could no longer see Wind's features with details, but he could still differentiate it with his body's frame. Although did he need to see with these skills of him.
"With this, it should be easier", he assessed as he eyed the potency of Wind's blood in front of him. "Weak…", a blurt escaped from his lips as he could see Wind's blood flow through his veins.
"Well… He never practiced body cultivation… But it doesn't seem to be a good idea for him to specialize in body cultivation…", he pondered on Wind's natural cultivation affinities with the three systems as he began to inspect his building to get used to his ability.
In front of Fell, Wind could feel his big brother's sight traverse his body. A bashful smile took over his face as he felt that the person in front him could see through every secret his body contained. His cheeks turned red and he began avoiding his brother's sight. "Terrifying…", Wind's soft voice resounded through his mind as he exclaimed in front of his brother's might.
Fell shortly ignored Wind's direction for his cultivation and focused back on his detection ability.
"Blood detection. I should focus more on this ability of mine starting now…" His mind kept working on the next courses of action as he kept trying to investigate the blood-related treasure.
"First let's see Blood Detection's maximal range." He thought as his sight turned into a growing bubble. His sight was no longer on a 180 degree but was turned into a mixture of his senses, becoming 360-degree radius.
This strange sensation was quite unusual for him, but he knew that this effect would dissipate with enough repetition.
The bubble expanded lightly, and as it grew. He began seeing the red bubble-shaped dot's in his surroundings. And as his blood detection skill expanded, other red dots were added to his mental chart. Their shapes differed slightly but what was unique to them was a strange flavor that each dot had. Fell could feel strange that every dot's essence was similar but different at the same time.
"Interesting…", Awakened by this discovery, his thirst for power followed suit as he continued his research. As the building completely appeared in his mental chart, each apartment's walls could be seen there. Although his blood detection's precision when it came to physical objects was average; It was more than enough to map his surroundings.
Then, as he felt that the range was more than enough. He began researching the slight difference in the essence of each red dot. He began with his own source of blood as he had the most potent blood in his surroundings.
"Researching the essence of my own blood is easy and hard at the same time", His eyebrows lifted into a frown as he pondered on a solution. "Although it is the most concentrated and potent, the fact that I'm a cultivator makes my blood essence thick and much more complete." His head rested on his chin as his eyes flashed with multitudes of lights giving Wind the impression that his brother was in the midst of doing something important.
