How to treat the character Xu Fengnian in A Sword in the Snow?

Although Xu Fengnian finally received a big wave of gifts, which formed his body of heaven and man, and the immortal who had been flying for hundreds of years came down to the north to supply air and enjoy the cool, he was still cut off by a big wave in the trap of Beimang, and even his body was broken. He can't beat Bodhisattva at all, and he can only turn into Qi by boiling blood. Referring to Luffy's second gear, I can barely beat the enemy.

Whether I can win or squander the luck I have accumulated as the king of Northern Liang for more than 20 years, as well as the luck of various allies. Finally, in a very short period of time, my luck far exceeded that of Bodhisattva Tuoba, plus my mood after killing Wang Xianzhi alone. In half an hour, I entered the first state in the world, but after the serious injury caused by Tuoba Bodhisattva could not be cured, I ran out of luck and fell back to my original state.

So I feel that Xu Fengnian's final strength is almost the strength of Li Chungang who re-entered the earth fairy, but with a stronger mentality, we can play a greater fighting capacity. If it's really a fight, there are still some people, such as Xuanyuan Qingfeng, Hehe Girl and Deng Taiya, but if it's really a fight to the death, you can still kill the rest of the masters to the death, as Wang Xianzhi said. After all, your mentality is different.
