There was no clear answer to why Ye Qingmei had drugged the Qing Emperor. Some documents mentioned that Ye Qingmei might have used the Qing Emperor as a seed to carry out experiments, but this was only a guess. The other documents mentioned that Ye Qingmei did not have deep feelings for the Qing Emperor. Some documents even said that Ye Qingmei did not love the Qing Emperor and only treated him as a tool. In addition, the Qing Emperor's killing intent towards Ye Qingmei might be because her thoughts and actions threatened the Qing Emperor's power and imperial authority. In short, we have no way of knowing why Ye Qingmei drugged the Qing Emperor.
There were several possibilities for Ye Qingmei to knock out the Qing Emperor. First of all, Ye Qingmei was a transmigrator. She had modern thinking and science and technology. Her dream was to create a world where everyone was equal. She hoped to support the Qing Emperor and help him ascend the throne. She also wanted to use his power to realize her dreams. However, her thoughts touched the interests of those in power and also buried a fatal disaster for herself. Secondly, Ye Qingmei had great power and influence in Qing Kingdom. She had set up a prosecutor's office, controlled financial power, and possessed many technologies that transcended the times. This fascinated the Qing Emperor, but it also made him feel threatened. Ye Qingmei's wisdom and understanding made the Qing Kingdom rapidly grow stronger. This made the Qing Emperor's mother dislike her and feel that she was a threat to the imperial power. Lastly, the Qing Emperor was a feudalist, and Ye Qingmei's ideals and thoughts were the opposite of feudalism. The Qing Emperor believed that Ye Qingmei's dreams and thoughts would make him lose the hearts of the people and affect his imperial power. In summary, Ye Qingmei drugged the Qing Emperor to realize her ideals and change the situation in the Qing Kingdom, but this also caused the Qing Emperor to be threatened and dissatisfied.
