You Asked for a Regretful Story, So I Wrote About the Chancellor's Northern Campaign!

The moment Su Yu opened his eyes, memories of his past life awakened. He discovered that he had been reborn in a parallel world. He was taking part in a global creative competition. Contestants had to create works based on a given prompt. When the first prompt appeared: Regret. While contestants from other countries wrote about regrets involving family, partners, and past experiences, Su Yu thought of the most famous Northern Expeditions of Shu Han from the history he had studied in his previous life! Even a thousand years from now, we will still wish he could have won. At first, the audience treated Su Yu's historical tale as a joke. “I'm dying. A 47-year-old middle-aged failure who keeps losing goes to visit an unemployed 27-year-old hotshot three times. Are they forming a losers' club?” “Where's the regret? Did you miss the prompt?” But as the story unfolded, the audience stopped laughing. The crossing at Baidi in white, the blazing fire at Yiling, and, at last, the appearance of the most devoted chancellor in the history of Huaxia, who worked himself to the bone until his dying breath, followed by the curtain call of the four-hundred-year Han Empire... Emperor Zhaolie of Han, Liu Bei: “If I do not avenge my sworn brother, then what worth is there in possessing ten thousand miles of land?” Chancellor Zhuge: “Vast heavens above, why are you so cruel to me?” Jiang Boyue of Tianshui: “My plan failed. It must be the will of Heaven!!” Then a new prompt appeared: Protagonist. “You may be the protagonists of your stories, but he is the protagonist of this era!” “The strongest carbon-based life-form of the seventh century, the Emperor of the Tang, His Majesty the Heavenly Qaghan!”
