How to evaluate the role of "Xu Fengnian" in A Knife in the Snow?

From Knife in the Snow? Xu Fengnian? This character is a super lucky character. The protagonist is full of gas, but his skill is average. Xu Fengnian's every step was clearly arranged by his father, who always wanted to do things according to his own rules, but in fact, he had already made corresponding arrangements for the method that Xu Fengnian wanted to use. So, along the way, Xu Fengnian followed his father in whatever he did, and was always protected by everyone, killing many people.

First, the whole drama "Giving charcoal in the snow" caused the protagonist Xu Fengnian to fail to shine. On the whole, this TV series "Giving charcoal in the snow" is not very brilliant, and there is no desire for people to pursue it. The main reason is that the plot drags on, and the protagonist setting is very general. Therefore, even if Xu Fengnian has much skill, he can't show it to the audience. What the audience saw was a clear story arranged by Xu Fengnian. May be in order to reflect Xu Fengnian's ability, the play also inexplicably arranged a Beijing partner for Xu Fengnian, if the plot behind can gather together, it can also explain Xu Fengnian's ability.

Second, Xu Fengnian in "Knife in the Snow" is very lucky. Xu Fengnian in "Knife in the Snow" couldn't learn martial arts at first. After being stimulated, he decided to learn martial arts. Then, by chance, the head of Wudang passed himself on to Xu Fengnian. Then another sword god, Li Chungang, taught Xu Fengnian his famous stunt, the green snake with two sleeves, and then passed the sword to Xu Fengnian. And Xu Fengnian also knows Lao Huang's swordsmanship, which has been passed down by the Peach Blossom Sword God, but why use a knife? I'm a little confused.

Third, everyone should protect Xu Fengnian and Xu Fengnian. They can't beat anyone along the way, but it's ok to bully some people who want to be heroes. However, every time Xu Fengnian is in danger, experts come to help him out. Even when Emperor Wu of the Han Dynasty took Lao Huang's sword box away from the city, a peach blossom sword god climbed up with him. Even Xu Fengnian said:? That's enough! ?
