Why did Yang Guo give the darksteel epee to Guo Xiang?

It is said that people in Wulin never leave their swords. The only weapon that Yang got was the dark iron epee left by the previous generation of Dugu Xia. Why did Yang Guo give this darksteel epee to Guo Xiang? There are two explanations.

One theory is that Yang Guo chose to retire with the little dragon girl, not to step into the rivers and lakes, regardless of the river's lake grievances. Since people are not in the Jianghu, the black iron epee will remain in Yang Guo's hand. It's useless to drag such a conspicuous black iron epee, or even a burden. Yang Guo managed to find the dusty darksteel epee from the sword grave. With Yang Guo's character, naturally I don't want to bury the darksteel epee back to the sword grave, so that it will never be seen in the dark. So the best way to deal with darksteel epee is to give it to others. With Yang Guo's foresight, he naturally knows that there will be a life-and-death battle in Xiangyang City in the future, so let the darksteel epee play its part in Xiangyang battlefield and continue to exert its residual heat!

Just as Wang Zhongyang can't directly pass on his exploits to Duan Wang, Yang Guo can't directly hand over the darksteel epee to Guo Jing and Huang Rong. Among the younger generation, Yang Guo is the most valued and reassuring one, and Guo Xiang is the only one. So before retiring, he handed the darksteel epee to Guo Xiang. ?

Another way of saying it is similar to seeking the experience of failure alone. Looking back at the process of Yang Guo's discovery of darksteel epee, there is a line written on the stone in front of the sword tomb? Sword and demon are invincible in the world, but where is the sword buried, alas! It's a pity that the hero is helpless and the sword is empty! ? There are * * * three swords in the sword burial. Yang Guo picked up the first sword on the right, which is soft sword in Wei Zi. The words "Wei Zi and soft sword" were used before the age of 30. It was unlucky to injure the righteous by accident, but they were abandoned. ?

Yang Guo took the second sword and held it with a darksteel epee. This line was engraved on the stone? The epee has no front, and the clever thinking is ineffective. Run wild before the age of 40?

Yang's third sword is an ordinary sword with a line engraved on it? After forty years old, all plants, trees, bamboo and stones can be used as swords, and after refining, they are gradually better than swords without swords?

When Yang Guo learned that the heroes of the previous generation had achieved the goal of winning without swords, he sincerely admired wood blade, sighed and respectfully put him back in his original position. It's hard to imagine the skill of the predecessors? Finally, under the guidance of Diao Ge, Yang Guo picked up the second sword, the darksteel epee. Yang Guo used darksteel epee to return to Jianghu and was attacked as a mighty eagle. His swordsmanship was also improved in the process of using darksteel epee. Finally, with Yang Guo's martial epiphany, he was able to achieve the goal of seeking defeat alone and not moving his sword. If no sword is better than a sword and flowers and trees can be used as swords, there is no need to continue to use darksteel epee.
