Liu Rong just took a nap during class, and when he woke up, he was dressed as Liu Rong, the prince with the same name more than 2,000 years ago.
The timing of the time travel is a bit ominous.
A son is valued by his mother, and Prince Liu Rong's mother-concubine Li Ji has fallen out of favor, causing him to be dethroned as crown prince.
Liu Rong: "A double loss is better than a single win, let's see how I can defeat this day!"
Intention: Eliminate difficulties in mind
