There's a saying that fear stems from the unknown.
For Gao Yang, the fear was clearly not because of the unknown, but the known.
Gao Yang knew the identity of the person sitting in front of him, and that was the real reason for his fear.
Cerberus, one of America's strongest two Special Forces units, the pinnacle of global superpower, the crown jewel, the sharpest point of the blade.
Yet Cerberus's strength was not the reason for Gao Yang's fear, because Gao Yang had faced and defeated both the Butter Knife and Cerberus, so Cerberus's power was at least not the sole reason for his fear.
Why would the commander of America's most elite unit apply for a job at Solar System Company? That's what Gao Yang feared the most, and in that sense, fear indeed stems from the unknown.
Gao Yang's first reaction was that his identity had been exposed and enemies came knocking, his second reaction was that someone sent Karl Stemonsen as an undercover agent.
