Chater 1537 : 3 matters Spoilers

Hey guys, I am on this chapter rn and I could not for the life of me understand the convo between Lu and Zhouwei... How did they start talking? I was so lost on what the plan they have for Li qianyuan and what plan others have and what are the options lu gave zhouwei that caused zhouwei to be pissed and lu to say that some may hate him for it? Basically can some one explain things to me like im a 5 year old?
