There was naturally no need for him to investigate such a small matter personally. Eunuch Wang had investigated it thoroughly.
The Emperor was poisoned after eating the stick of candied hawthorn. The poison must have been on the stick of candied hawthorn. Eunuch Wang was an experienced worker in the palace. After thinking about it, he guessed it in his heart.
In order to verify his guess, he took all the candied hawthorn that the three little black eggs had given to the Emperor to let Yu Wan test the poison.
Yu Wan soaked the candied hawthorn in clean water and tried with the silver needle. As expected, the silver needle turned black.
These candied hawthorns were originally for her sons. If the Emperor hadn't interfered and used Fuyuanzi to exchange for their candied hawthorns, her three precious sons would have been poisoned.
The things were bought by the Queen, so she was the most suspicious. However, Yu Wan did not think that the culprit was her.
