It's a flying sword.

The sword body was covered with black rust marks, and it broke from the interruption with a light touch. The fragments turned into powder and scattered little by little in the wind.

The firefly came from a gem on the hilt of the sword, and the slight light seemed particularly distinct in the dust.

I don’t know the material, and I can’t tell the history even if I look closely, but it’s a bit similar to something in my memory, so Zhou Shu took it back to the Demon Refining Realm.

The newly built Hokkien School has complete facilities and no disciples, so Caiying brought the monkeys and pretended to have a sect opening ceremony. The scene was hilarious. Now when Zhou Shu saw the Hokkien School, he would still think of that day.

Zhao Yueru, who had just come out of the secret realm, is resting.

After suffering a serious injury, she also felt a lot. Seeing Zhou Shu, she stood up, with unconcealed joy on her pale face.

Zhou Shu said in a gentle voice, "Come and take a look at this thing, Yue Ru."

Zhao Yueru walked gently, looked at Zhou Shu's palm, and suddenly shook, "Shushan Sword Stone?"

Zhou Shu had expected it, "You read it right? Then it seems that it is really a sword stone."

“There will be no mistake.”

Zhao Yueru was very confident, "I have been guarding Jianshan for hundreds of years. I can see those ancient flying swords every day. A small number of swords have sword stones on them. Just like this, Zhou Shu, where did you get it?"

Zhou Shu was very calm, "The Dead Land, there must be a disciple of Shushan who died there. This thing should be very precious, right?"

"Precious? It should be said to be a treasure."

Zhao Yueru was very excited and retorted abnormally, "In the past, when Shushan disciples sealed the sword, they had to use the help of the elders to condense their lifelong understanding of swords into the sword stone and collect them together with the flying sword to the sword mountain. Each sword stone represents the lifelong essence of a Shushan sword cultivator and is a treasure. At present, Shushan has only 45 sword stones in total. Speaking of value, it is more valuable than the ninth-grade flying sword."

Zhou Shu seemed to be thinking, "I heard that the method of condensing sword stones has been lost?"

"It was lost very early. It was the method left by Li Jing, a sword saint in Shushan. Those who do not have great wisdom cannot learn it. The previous elder who mastered the stone setting method was Han Sha. She left Shushan for 70,000 years and has not yet heard of it. Since then, no one has learned the stone setting method. Gradually, even the magic trick disappeared, and it is still a heart disease in Shushan."

Zhao Yueru sighed.

Zhou Shushu said in a relaxed voice, "Does Shushan disciple Feng Jian mean that he will no longer use swords in the future?"

Zhao Yueru nodded, "Yes, most of them are forced to advance without hope of life. They have cultivated juniors for Shushan, but there are also people who have signed swords and retired from the sect in the middle. This type of person is rare. People can leave, and the sword must be kept. The sword path learned in Shushan will not be reclaimed, but they must be deposited in the sword stone for those who are destined to be."

Zhou Shu said suspiciously, "Doesn't those who become sword saints need to leave sword stones?"

Zhao Yueru nodded and shook her head again, "After they become saints, they will also seal swords, but the condensed sword stones will turn into mountains and become part of Jianshan. This is how the sword mountain in Shushan comes from."

Zhou Shu smiled, "But I was wrong. It should have been like this. Yueru, you know a lot. These should be secrets, right?"

Zhao Yueru thought for a while, "I don't think it's secret, I think everyone around me knows it, and they don't care."

Zhou Shu paused and pondered, "You are a sword-protecting disciple, and so are the people around you. If you change to other disciples or even elders, you may not know so clearly. I think Shushan is actually good for you. I think they should hope that you can understand yourself in Jianshan and then find your own sword path. The heart of the mysterious sword is not so easy to find, and they are considering it."

"Why did you say this suddenly..."

Zhao Yueru looked at Zhou Shu, blinked, and was very determined, "No matter what you say, I will not go back."

"You misunderstood, I'll just say it casually."

Zhou Shu smiled and shook his head, "Continue to talk about sword stones. These insights are sealed in the sword stones, and then they are kept in Jianshan without moving?"

Zhao Yueru thought for a while, "No, every fifty years, the sword mountain will be opened. Every day, let the genius disciples go in and look for opportunities. If you are lucky, you may realize the truth, and even take out the flying sword and sword stone inside. However, in the past few hundred years, no disciple can take out the things from the sword mountain. Shushan is also very anxious about this. Some elders even secretly take out the flying sword and sword stone for their disciples, but at most two days, they will be discovered by the sword mountain elder, reclaimed and punished."

She paused, stared at Jianshi and sighed, "What kind of insight can you get in just two days? It may not be possible for two years or two hundred years."

Zhou Shu smiled, "You can use this sword stone to understand it, and you can think of it as long as you want."

Zhao Yueru didn't say anything, but just nodded slightly. Because she was too excited, her face turned red quickly and looked like a cloud of clouds, "Don't you need it?"

Zhou Shu shook his head, "My sword skills are not as good as you, and even worse than Caiying. It's okay to teach me when you learn it. Besides, I don't know anything about sword stones and don't understand it no matter how I understand it. Yue Ru, from the level of the flying sword, the sword cultivator who condensed into sword stones should not be too high, and you shouldn't overestimate it."

As he said that, he took out the Kunlun mirror and placed it lightly in front of the sword stone.

Zhao Yueru looked at him in a little confused, not knowing what it means.

Of course, Zhou Shu had to take a look. The sword stone is an antique, an antique from at least 70,000 years ago, so it is worth it to pay some reincarnation power for this.

On the Kunlun mirror, a cloud floated, and a mountain gradually appeared.

The clouds surround the fog, and the mountains are continuous, with hundreds of peaks protruding from the clouds, like chess pieces on the chessboard.

"Sword Mountain!"

Zhao Yueru shouted unconsciously, she was so familiar with this scene.

The picture quickly went down, under a mountain, two people sat opposite each other, a young woman and an octogenarian.

"Han Sha real person!"

Zhao Yueru shouted again, more excited than before.

Zhou Shu was stunned, "Is that old man?"

Zhao Yueru shook her head quickly, "No, it's the female sword cultivator. Her portrait is hanging in the sword hut in front of Jianshan. I can see it every day. I never thought I could see her here, Zhou Shu, your mirror..."

Her breathing was a little rapid. She could see what happened tens of thousands of years ago, but she had never thought about it.

Zhou Shu roughly introduced Kunlun Mirror, and felt a little worried.

Zhao Yueru's eyes became brighter, as if she could see Zhou Shu's concerns, and said calmly, "Zhou Shu, you should have told me these things that they were right not to tell me."

The worries quickly disappeared and were very peaceful. Zhao Yueru was still the elder in the past.

The mirror will not wait, the scene inside has been changed.

The young Han Sha Zhenren silently recited a magic trick, and the sword in his hand drew a circle of strange ripples, facing inward rather than outward. The old man sat in the ripples, as if he was integrated with Jianshan, with only a little light coming out of his fingertips, which became more and more solid as the ripples narrowed.

It is obvious that it is condensing the sword stone.

What Han Sha is doing is probably the lost stone-condensing method in Shushan.

Zhao Yueru's heart was shocked, and she tried her best to remember and understand. That was the magic trick that had been lost in Shushan.
