0542's current power reserves were so low that if Jiang Fei were to fight them, he would not survive even the preliminary blows.
Fortunately, the "investigative" probe of power that Lockwood had projected towards Jiang Fei was incredibly weak. To be honest, probing someone else to obtain their information without their consent was rude. The reason why Lockwood only projected the most minimum amount of power into Jiang Fei was because of fear. Even if he was a Level 5 Metahuman, the man that he was probing was the legendary Zhuge Shanzhen. If the power was slightly higher, it would be taken as an act of attack. He would have been crazy if he thought he could take on Zhuge Shanzhen.
