Chen Jingzhai could not be bothered to deal with Lord Dong. This fellow was not a good person either.
If he was truly doing this for Chen Jingzhai's sake, Lord Dong should be shielding him from Lord Yu.
If he did so, even if Chen Jingzhai did not appreciate it, the Luo Sheng Sword School would and would offer him gifts in return.
However, he was now saying all these things in a manipulative manner, pretending to be doing this for Chen Jingzhai's benefit when he actually wanted Chen Jingzhai to surrender the spiritual treasure to him and seek his protection.
Lord Dong was implying that surrendering the treasure to either of them was essentially the same.
By that logic, Chen Jingzhai giving it to him was more worth it than giving it to Lord Yu!
