Far away in the capital city, both Prince Chu and Prince Wei received a letter from Zhao Yao. In the letter, Zhao Yao informed them that Prince Han wanted to collaborate with him in business and would send someone to Swamp Prefecture. He specifically sent someone to investigate Prince Han, and the result was that Prince Han had been doing business in Youzhou and also had trade interactions with the Western Regions. Apart from business dealings, Prince Han had not been involved in any other activities privately. At the end of the letter, he emphasized repeatedly that he felt Prince Han might not be as "innocent" as the investigation suggested and urged Prince Chu and Prince Wei to be vigilant against Prince Han.
Yang Ling noticed that Prince Chu's face seemed somewhat upset after reading the letter and promptly asked with concern, "Your Highness, what did His Highness Prince Han write in the letter?"
Prince Chu handed the letter to Yang Ling, "Sir, please have a look."
