Zhang Yun's martial arts skills were quite outstanding, otherwise, Zhang Ping wouldn't have entrusted him with being a secret agent.
But compared to Zhou Gu, his martial arts was still inferior. Thus, when Zhou Gu attacked him by surprise, he was caught off guard and resisted in a panic. After a loud scream of terror, Zhou Gu was still able to stab him in the chest.
Zhou Gu knew that the stab didn't hit his vital organs, so this wasn't a fatal wound. He could deliver another strike, but if he did, he wouldn't be able to escape.
After all, this was a military camp housing two hundred thousand troops, not a playground.
So, after successfully landing the first blow, Zhou Gu didn't insist on finishing him off. He turned around and walked away.
He left swiftly, only crossing paths with Zhang Yun briefly before leaving his tent.
Outside, there was a commotion.
