Saving the Heavens at the End of the Jin Dynasty

I woke up to find myself transmigrated to the first year of Yong'an (304 AD), in the body of Sima Zhong, the famously foolish Emperor Hui of Jin in Chinese history.

At present, the Sima clan had seized power illegitimately, the emperor was mentally impaired, the royal family was fighting among itself for power, aristocratic clans stood everywhere, and the non-Han peoples were rising amid the chaos. The disastrous era of the Five Barbarians ravaging China and the southward flight of the nobility was just around the corner.

Sima Zhong resolved to change the outcome of the Five Barbarians' invasion of China.

But although he was the emperor, he was known for being a fool. For now, he was merely a puppet in the hands of the princes, who were struggling for power. He couldn't even leave his carriage without a eunuch's permission, and had neither authority nor prestige.

How could he break out of such a predicament?

Fortunately, he had transmigrated to the eve of the Battle of Dangyin. Then let him start by changing the outcome of that battle.

Zu Ti, Ji Shao, charge with Us! Princes, aristocrats, and non-Han peoples, We will deal with you one by one! If We don't save all the people under Heaven, then who will?
