I recommend "Bringing Netizens to the Eastern Zhou Dynasty" to you. This historical novel tells the story of a young man who mistakenly possessed the Emperor of the Zhou Dynasty and became the most miserable King Xiang of the Zhou Dynasty. However, he communicated with the people of the crisis era through a huge bug in his transmigration and proposed a grand idea to transform the Eastern Zhou Dynasty. In the process of seeking help from various big shots and realizing this grand plan, all kinds of interesting stories happened. In the end, the protagonist returned to his previous appearance. I hope you like my recommendation, Mwah~
