Chu Li was not actually satisfied.
He was only able to display his skills in presenting ideas if he were able to talk to the High Duke But now that the witness had been discovered, he was only able to clear himself of suspicion, at most. This did not affect Lu Yurong in any way and it was such a wasted opportunity.
Chu Li did not like to be defensive when he did things. He enjoyed gaining the initiative and striking first. He always wanted to make the first move.
Lu Yurong had been thinking about plotting against him and at the same time, Chu Li had been plotting his own revenge against her. This was a good chance but he did not seize the opportunity in time because he did not expect the Public House to be competent enough to stop the witness. His plans were washed away and there was nothing he could brag about.
