Zero Day Mercenary

At the end of the college entrance examination, 18-year-old Lin Mo went to a small border town with a second-hand laptop. After his father died in a "training accident", the family was too quiet. His only pastime was to scan for WiFi signals—2.4GHz, 5GHz, and copy the BSSIDs into files one by one. When anxious, he counts prime numbers. 2,3,5,7,11,13…… Then he saw things in the spectrum that shouldn't be there: encrypted military signals, directional antennas, hidden networks. Then the bomb went off. When he was lying on his back in a messy border market, his palm cut open by a barbed wire with a wound from his palm to his wrist, a former retired mercenary of the Russian Alpha Special Forces saw him through the telescope - this thin Chinese teenager, using a laptop, did what their entire intelligence team failed to do. Viktor Kovalenko gave him two choices: go home and forget everything. Or follow me. From WiFi penetration to SCADA attacks, from being unable to run 800 meters to marching with a heavy load for 40 kilometers, from being the "IT guy" laughed at by his teammates to everyone waiting for him to hit Enter before they dare to pull the trigger—— The keyboard is the first weapon. Glock is the second one.
