Wei Zi fell off a cliff.

Four swords belong to the solitary sword grave. They were thrown from the cliff, picked up by unknown people, returned to Yang Guo's hands, and rotted wood blade. These four swords are Qingrui Sword, Wei Zi soft sword Sword, Tie Xuan Sword and Ordinary wood blade.

First, the green sword left in the sword tomb. The Qing sword is the first sword used for loneliness and defeat. Its body emits blue light and is very sharp. The description of the Qing dynasty sword on the pillow stone of its sword tomb is:? Sharp and invincible, before competing with Heshuo for the weak crown? . From the description on the pillow stone, we can know that when loneliness and defeat just came out of the Jianghu, they used this sword and swordsmanship from primary school to fight with people in the Jianghu, but at that time, loneliness and defeat had not realized the meaning of the sword, and dueling with people depended on posture and sword. From this sword, we see a confused and competitive teenager who has just come out of the river and lake.

Second, Wei Zi soft sword was thrown off a cliff and picked up. Wei Zi soft sword was a sword he used when he was lonely at the age of 30. There are two gold seal characters on the hilt: Wei Zi. This sword was thrown into the depths of the cliff by myself. The reason is that we can know from the pillow stone of Wei Zi soft sword that although there was no sword, a sword tomb was built for him when he was lonely and defeated, and the description of Wei Zi soft sword on the pillow stone is:? Soft sword, Wei Zi, used it at the age of 30, accidentally injured the righteous man, but abandoned the deep valley? . I can know from the pillow stone that this sword was used when I was 30 years old. However, I accidentally injured a loyal person in a competition, and I threw Wei Zi soft sword off a cliff because of regret.

Third, Yang Guo's black iron sword and rotten wood blade. The black iron sword is a sword used when you are 40 years old and lonely. This sword is invincible in the lonely and defeated rivers and lakes. The description on the pillow stone is:? The epee has no front, and the clever thinking is ineffective. Forty years ago, it ran amok all over the world? Finally, this sword was taken out of the sword grave by Yang Guo. And the last sword has rotted in the sword grave, because it is just an ordinary wood blade, and the description on the pillow stone is:? After the age of 40, all plants, trees, bamboo and stones can be used as swords. From then on, after refining, no sword is better than a sword. . This sword was used by wood blade after 40 years of loneliness and failure. At that time, he already knew kendo, and the sword was not important to him, which also marked that he had reached the highest level of kendo.
