In "Swordsman in the Snow", why does Deng Tai'a have a double standard attitude towards Xu Fengnian?

Swordsmen are the most popular tourists in the snowy arena. Among the masters of the arena in the past, swordsmen have won the most championships. There are Li Chunchun in the century-old snow, opening the gate of heaven with one sword, Deng Taiya, the peach blossom sword god, the veritable princess of Beiliang, Wu Su, the sword emperor of Xishu who defends the city with one sword, the Ninety-six Thousand Miles Sword Yellow Formation, and the food that spits out swords for hundreds of years. The sword monster Sui, the sword-eating tomb of Nine Swords and Ten Thousand Riders. Kendo can be said to support half of the world in the snow. Today, let’s talk about this peach blossom, the undefeated peach blossom sword god Deng Taiya. When it comes to swordsmanship in the snow, there is one person we cannot avoid, that is the old swordsman Li Chungang, but in the new generation of martial arts, martial arts knights are more familiar with the peach blossom swordsman Deng Taiya. Li Chunchun has wooden horses and oxen, and is invincible in the world; Deng Taiya has peach blossoms, and no one dares to compete with them.

To be honest, I still think Li Chunyu is more to my taste than Deng Taiya. Both of them are sword gods, but I think the sword god Li Chunyu is more domineering, sweeping the world for a generation, which is convincing. And Deng Taiya, although he is the Peach Blossom Sword God, I think he should be called the Sword Immortal. He is too half demon and half immortal, too far away from the world, and rarely takes action after his debut, so fighting with Wang Xianzhi, Cao Guanzi and others makes people feel like people in the sky, not grounded enough. Of course, I have to say Deng Taiya's sword. Even if he's not as convincing as Li Chungang, his sword isn't vegetarian. Deng Taiya practices swordsmanship, unlike Lu, Li Chunyu, and Qi Xianxia, ??who follow the path of swordsmanship.

Deng Taiya pursues the art of swordsmanship. In the early stages of the book, his swordsmanship surpassed the two realms of his peers and directly caught up with Lu's sword. Reached its peak later. According to the theory, since the sword has been around for thousands of years, regardless of the way of swordsmanship, swordsmanship was originally a method that Lu abandoned after pursuing the way of swordsmanship. And Deng Taiya took a technical path that is close to the Tao and proves the Tao with skills. Before his death, Li Chunyun borrowed a sword from Emperor Wanli to illuminate the way forward for Deng Taiya. Deng Taiya, a queen who traveled to the East China Sea to become an immortal, gained enlightenment in the East China Sea and was promoted to a swordsman with the skill of "riding a sword" and entered the fairyland of the earthly gods.

The above answers are my personal thoughts.
