Fang Zheng smiled and said, "Since you want to know, I'll tell you!"
"A few months ago, I personally led a team to execute an A-level task. However, the task failed. I was severely injured and ended up in Jidong City. With nowhere to stay, I met He Dahai. With my skills, I temporarily stayed at his place and worked as a bodyguard!"
Fang Zheng said, taking a puff of his cigar, and continued, "I stayed at He Dahai's place for a while, healed my injuries, but eventually, I had a falling out with He Dahai. Then, the rest of the story you already know!"
Ye Long listened to Fang Zheng's brief explanation and roughly understood the situation!
Basically, Fang Zheng executed a task, ended up in Jidong City, and to find a place to stay, went to He Dahai's place, then had a conflict with He Dahai, and Fang Zheng set up his own base in opposition to He Dahai!
The rest is He Dahai hiring a female assassin to assassinate Fang Zheng!
