Although Wu Changlin agreed to help Prince Huai, he couldn't agree to Liu Ji's suggestion. Agreeing would not only place him in a position of filial impiety, but also make him an unscrupulous person who doesn't value trust and integrity.
Being unfilial means hiding this from his father Wu Yanqing, and ultimately putting his father on a roasting spit.
Being untrustworthy refers to deceitfully luring Chen Mo to Jiangdong to harm him under the guise of marriage.
If the scheme succeeded, it would be fine, but if it failed, as the heir of the Wu Family, how could he explain it to the family? His reputation among the clansmen would greatly diminish, causing his prestige within the clan to plummet.
After all, how could someone who is unfilial and unrighteous lead the entire Wu Family?
Therefore, despite Wu Yu's persuasion, Wu Changlin remained firm in his stance.
Helpless, Wu Yu had to inform Liu Ji of the outcome.
