Gu Yi, a top science prodigy with an "extreme fear of insufficient firepower," goes alone to a war-torn region of the Middle East to work as a mercenary, hoping to raise a huge amount of funding for his research.
Other people fight with their lives on the line. Gu Yi fights by putting his knowledge of math and science to good use.
No high-explosive mines? He handcrafts miniature fuel-air explosives with fertilizer and sugar.
No air support? He turns civilian DJI drones into a swarm of suicide bombs with a complete overhaul.
No armored vehicles? He welds steel plates onto a secondhand farm pickup and installs a homemade electromagnetic generator so it can withstand RPGs!
His veteran partner, who has lived and died alongside him, is scared out of his mind. "Boss, we only took a little job escorting a merchant. Why are you making thermobaric bombs?!"
Before long, the outside world goes completely crazy.
The warlords: "Run! The Shura Mercenary Corps' steel tide is rolling in!"
International intelligence agencies, their scalps tingling: "Investigate! There must be a top-tier military-industrial complex from a major power backing Shura!"
Facing the fear and trembling of forces around the globe, Gu Yi pushes up his glasses and sighs helplessly. "I'll say it again: this is really just private-sector technology. Do you even know what basic physics is?"
