Nirvana in Fire was a web novel with strategies, political struggles, and power struggles as its main theme. Although the author had spent a lot of time on the character description and plot design, there were still some unreasonable parts in the plot. The following are some possible problems: Mei Changsu did not become the Emperor's opponent. In the novel, Mei Changsu had always been regarded as an outstanding politician and strategist, but he often fought with the emperor. However, in the second half of the novel, the emperor has become increasingly shrewd and even surpassed Mei Changsu's ability in some cases. This made Mei Changsu's entire role unreasonable. 2. The power of the Marquis of Laiyang was too great. In the novel, the Marquis of Laiyang was an extremely powerful force that controlled almost the entire imperial court. However, the source of this power was not legal but came from the internal struggles and power struggles of the family. This kind of power would lead to instability in the country, so the author's description of the Laiyang Marquis's residence in the novel had certain problems. 3. Mei Changsu's son, Prince Mei, had a problematic persona. In the novel, Prince Mei was a very intelligent and ambitious character, but his actions and decisions were often influenced by his father and brother. This made his character image not independent, firm, and reasonable enough. 4. The role of the eldest princess is contradictory. In the novel, the eldest princess was a very important character. She was the emperor's sister and a powerful figure. However, her behavior and decision-making in the novel are contradictory and unreasonable. For example, her attitude towards Mei Changsu and the Crown Prince was obviously wavering, which made her character image not three-dimensional and profound enough. Although there are many highlights in the character creation and plot setting of Nirvana in Fire, there are also some problems that need our attention and consideration.
