**Protagonist**: Xiang Yi, a modern history student/young officer, whose soul traveled to Xiang Yu on the eve of the Battle of Julu. He not only inherited Xiang Yu's martial prowess of "being able to carry a cauldron", but also integrated modern people's knowledge, strategies and patterns.
* **Core Conflict**: It is not a simple conflict between Chu and Han, but a thrilling game between "known history" and "unknown future"**. Every step the protagonist takes is like walking a tightrope. He must make use of historical knowledge while always being wary of the "butterfly effect" caused by his own intervention.
