18-Year-old Lin Chen is a "problem boy" known to everyone in Jiangcheng No. 1 Middle School - he sleeps in class and turns in blank papers in exams, but no one knows that he is cracking the encrypted database of the transnational criminal organization "Darknet Snake" in real time on his mobile phone hidden under the desk. Three years ago, his parents, who were top agents, mysteriously disappeared while on a mission, leaving only half a badge with "Thunder" engraved on it and the last words "Look for the Dragon Team, believe in Thunder".
In order to find out the truth, Lin Chen disguised himself as a rebellious young man, secretly active on the dark web under the code name "Lone Ying", and relied on his extraordinary hacking skills to collect clues about the "Snake of the Dark Web". Until an accident, he cracked the "Pandora Base" where his parents were trapped in the "Snake of the Dark Web", but because the traces of his operation were exposed, he attracted a killer to pursue him.
At the critical moment of life and death, the mysterious female agent Su Qing rescued him with members of the "Dragon Group" and handed over the other half of the "Thunder" badge: "Your parents are the legendary agents of the 'Dragon Group', and 'Thunder' is their joint code name. Now, it's your turn to accept this badge."
From then on, Lin Chen shed his disguise as a "problem boy", put on a tactical uniform, picked up a modified gun, and transformed from a dark web hacker into the youngest agent of the "Dragon Group". He sneaked into drug lords' dens in Southeast Asia, cracked the frozen laboratory in the Arctic Circle, fought life and death battles with genetically modified warriors in the Amazon rainforest, and stepped closer to the core conspiracy of the "Snake of the Dark Web" - using "consciousness control chips" to control global politicians and subvert the world order.
On the way, he met the rebellious commando Zhao Hu and the beautiful agent Luo Xue who was proficient in disguise.
