Have you ever thought that the state of the world as it presently is, could revert to the laws of the ancients? When a series of strange incidents beginning with the disappearance of his friend led Luo Yuan to question the possibility of an apocalypse, he becomes embroiled in the midst of a global-scale chaos. Evolution has turned the flora and fauna of the vast and bountiful Earth into something that had never been seen before. Coincidentally, the all-dominating Homo sapiens have ended up at the bottom of the food chain. From mystery to crisis, will Luo Yuan discover a means of saving humanity by racing to the top of the food chain? Or will he strive in accordance with the law of the jungle? It is the dawn of an age of the survival of the fittest.
What was a feeling? A wave of knowledge filled him and soon, Luo Yuan got the answer.
From a psychological perspective, feelings resulted from the strong mental reaction to external stimuli where actions were revealed unintentionally. Showing great concern for person or thing and emotions of love and hate was a unique way of expressing oneself to the objective reality. It was the human attitude towards an objective matter whether it fulfilled one's personal requirement.
On the other hand, from a biological perspective, it was a biofeedback where a person would choose situations that would give one an advantage, avoiding those which put one at a disadvantage. It was an electrochemical reaction where the secretion of hormones was taken into consideration.
However, no matter how well he could understand the definition of feelings, Luo Yuan found out that he could not feel it at all.
