When watching the TV series "Sword Line in the Snow", Zhao Kai, who had originally followed Xu Fengnian all the way, really racked his brains to kill him, but on the walls of Emperor Wu's city, Xu Fengnian insisted on saving Zhao Kai from Zhao Xuansu's hands. As the saying goes, there must be a demon when things go wrong. This unusual detail must hide secrets that are difficult for outsiders to know. So why did Xu Fengnian want to save Zhao Kai, if Zhao Xuansu killed Zhao Kai, wouldn't he save a lot of trouble? Specifics, and see the following details.
First of all, Xu Fengnian had a clear understanding of Zhao Kai's details and kept it useful. In the play, we see that Zhao Xuansu did not dare to attack Xu Fengnian and had to kill Zhao Kai. This is certainly not a gratuitous thing, and it must be supported by some force behind it. At the same time, Dragon Tiger Mountain has always been favored by the imperial court, which must involve the participation of the court. For Xu Fengnian, facing Zhao Kai, who had already figured out the details, was not a powerful threat at all, but keeping him would be able to figure out who was behind the scenes. In this way, it will help to accelerate the internal differentiation of the Yang Dynasty and reduce the pressure on the Northern Starling. Of course, these are only superficial reasoning, the fundamental purpose, it is estimated that Xu Fengnian and the capital of the connection, to reach some kind of deal, to ensure zhao Kai's temporary safety, just like Xu Fengnian all the way to Emperor Wu City, local forces everywhere, but also carefully maneuvered to ensure its safety.
Secondly, Zhao Xuansu is also a sad person, pretending to be a grandson for so long or failing. Originally, Zhao Xuansu's purpose of going out of the mountain was two, one was to kill Zhao Kai and Xu Fengnian, complete the tasks assigned by the imperial court, and also repay the favor of the imperial court and maintain the peace of the world; the other was to use the peak duel between Li Chungang and Wang Xianzhi to take the opportunity to fly across the Shengxian. As a result, these two tasks failed, and the grandsons on the road here saw that everyone was shouting at the big brother and sister, but in the end it was a bamboo basket to hit the water, which was really ironic. At the same time, Zhao Xuansu also told Xu Fengnian that his inner palace had decayed and that his qi was about to run out, which made Xu Fengnian sure to intervene, stop him, and save Zhao Kai. Otherwise, Xu Fengnian may not dare to shoot, and it is difficult to guarantee that the ending is not tragic.
All in all, zhao Xuansu, an old traitor and a giant, not only did all the plots not succeed, but also offended many forces such as Beilin and Zhao Kai, and their own plan to ascend was also frustrated, which can be described as a failure and nothing. Such an ending, compared with the previous small bow posture, is really of great irony.
