Epoch of Twilight
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.
Luo Yuan lowered his body and went through the thick metal door. Underneath the door was a typical basement staircase, and on both sides of it there was light. It was as bright as daylight.
After crossing five levels about 20 meters deep, they entered a long, three-meter wide channel. Every twenty meters, there was a soldier on duty. It was a pretty tense atmosphere, and everyone could feel the pressure.
Luo Yuan knocked on the wall of the channel with his weapon's handle. Using his Sensory Perception, he discovered that the wall was more than a meter thick. That kind of thickness could withstand even a cannon bombardment.
Luo Yuan was relieved. Against such defense, even a green level mutated beast would need to put some effort to break in. He continued to walk for another minute, passing by three thick metal doors, each about 50 centimeters thick. The noise got gradually louder as the team reached the hall.
