Jiang Yan Hai did not fire. He did not even need to ask who had hired these mercenaries. Who else could it be besides the CIA bastards? Either the CIA or the U.S. government.
In short, they were probably trying to kill Liston Han Xiao because he had interfered in Jason Bourne and Allen's affairs and learned too many of their secrets.
So they had flown into a rage out of humiliation or something.
To be honest, Jiang Yan Hai had no way to deal with the CIA and the people behind it. The reason was simple: this was not something that could be solved by killing one or two people, nor could it be resolved by exposing a few things.
Jason Bourne and the others were far too naive. This was reality, not a movie. Things were not so easy to settle. Had anyone ever seen a government agency stop operating just because a few people died or a certain project was exposed?
Too naive. No country would care about that. Did they think projects beneficial to the entire nation would simply be abandoned because a few problems arose?
Although Eric was a project leader, and even the fat old senator behind him did not know what he was doing, could a mere project leader like Eric really hide so many projects from the entire government and carry them out alone?
Give him a break. Without approval from the very top, there was no way he could pull this off.
The resources alone were not something one or two people could mobilize.
But neither the CIA nor anyone else could directly hire mercenaries like these. They would go through intermediaries, people like the church contact who dealt with the Suicide Squad.
Jiang Yan Hai was looking for that intermediary.
