But thinking about this, it's a bit too harsh; using Nian Yao's servant status to sow discord between him and Chu State is too formulaic.
In the end,
Lord Zheng simply wrote a letter to Nian Yao under the guise of a distant friend:
Dear Nian...
Lord Zheng took a deep breath and changed to a new sheet of paper.
Seeing the letter as meeting...
Lord Zheng changed the paper once more.
You damn fool, don't you think your shell is hard? I've already broken so many of them for you!
Hmm,
Satisfied.
Subsequently, Lord Zheng wrote about some scenic spots and snacks of Yan State, and then explored the famous sights and snacks of Chu State.
After writing, the work was done.
"Prince, the letter is finished."
"Have someone send it out."
Clearly, Prince Jingnan didn't plan to read it.
"Yes, Prince."
"Zheng Fan, come over."
Lord Zheng walked over to the sand table.
Tian Wujing opened his hand, and Zheng Fan's machete was unsheathed, landing in his hand.
