At the end of the Western Jin Dynasty, the court was corrupt and the people were in dire straits. Shi Le, a Jie tribesman who was born as a slave, and Zhang Bin, a Han Chinese, raised a banner to raise rebel soldiers and rebel against the imperial court. Shi Le was full of remonstrances, and Zhang Bin knew everything and made every plan. The two worked closely together, with infinite wisdom and perseverance, to finally overthrow the decadent Western Jin Dynasty, unify northern China, and lay the foundation for the unification of the country.
