After Sun Yixie and Huang Donglai had passed two rounds, Xue Tui's attitude towards them was completely different from when they first arrived.
Now, Xue Tui no longer thought of them as country bumpkins who had stumbled in by mistake, but rather began to see them as wily newcomers in the Martial Arts world, who pretended to be pigs in order to eat tigers.
In the presence of such characters, Xue Tui couldn't possibly make the questions too "ordinary," otherwise he would seem to be lowering his standards.
Yes, generally speaking, the content of the third round was for him, Xue Tui, to personally pose questions and engage in "literary battles" with his opponent; and "literary battles" typically meant composing a poem, matching couplets, guessing riddles, and the like.
It was precisely because Xue Tui was exceptionally adept at this that he had earned the nickname "Little Dezu"; meaning... he had quite a bit of the style of the famous scholar Yang Dezu.
