Neon flashes and invisible black trickles linger.
In an accident, Tang Nishuo saw his sister Tang Fei being seriously injured by a mysterious animal in the countryside. Later, he joined a mysterious organization "Riyin" and understood what that animal was.
Tang Nishuo became a reserve member, and during the training, he made lifelong friends. They grew up together, sweated and shed blood, and embarked on the road of killing.

Can Tang Nishuo peel off the cocoon and find the truth?
Can the beast tide be resisted?
What is the secret hidden behind Tang Nishuo?
Stay tuned... Neon world!
Intention: The world is beautiful and warmth flows
