"Master Jiansheng, you are mysterious. What's the matter?" Li Xiaoyao immediately asked curiously.

He wanted to know what was going on, so Zixuan thought she needed to contact the chat group to solve it.

"Since you are a disciple of Yixi, you know something about Shushan, don't you?"

"You should also know the details of Shushan."

"Among the six worlds, although there are six independent worlds, there are still ways to communicate with each other."

"In the world, it is Shushan who is responsible for communicating the six realms."

"But fifty years ago, the 'boundary stone' in charge of communication between Shushan and the heaven suddenly dimmed. After inspection, we found that the heaven suddenly interrupted communication with Shushan."

"This situation has continued until now."

"But just yesterday, the 'boundary stone' suddenly lit up again, but it only lit up for a while, and then it dimmed down again."

"All the elders of Shushan and I feel that this matter is unusual. After deducing the secret of heaven, we get a great omen of evil. In the near future, the world is afraid of great changes."

"But at present, we have too few clues to draw any effective conclusions. Therefore, I went to consult master Zixuan."

"But master Zixuan recommended you to me, Xiaoyao. I don't know what you think?"

The sword Saint asked Li Xiaoyao with a straight face.

"Elder martial brother, the 'boundary stone' in the heaven has been on for 50 years, 50 years!" Jiu Jianxian sighed.

"No matter how powerful I am, I won't come up with any clue so soon," said Li Xiaoyao with a forced look on his face. "I need to think about it."

Think about it, but in fact, it's just to enter the chat group and discuss with everyone.

"No, fifty years ago..."

But at this time, Li Xiaoyao couldn't help but move in his heart.

Because he thought of one thing, "I remember that senior Xu Changqing, the world's first swordsman, suddenly disappeared 50 years ago?"

"Yes, the time is consistent. We once speculated whether the failure of the boundary stone would be related to elder Xu Changqing, but there is no basis."

"But I just learned from master Zixuan not long ago that master Xu Changqing suddenly disappeared 50 years ago and went to the heaven! So now we have reason to suspect that master Xu Changqing is related to the failure of the boundary stone."

"In that case, can we infer that the short and sudden recovery of the boundary stone a few days ago is also related to elder Xu Changqing?"

At present, there are few clues. We can only doubt whether this matter has anything to do with Xu Changqing, but no one has a final conclusion.

"Well, I'm going to start sorting out my ideas now. Don't disturb me!" Li Xiaoyao began to pretend a force and entered the chat group.

Everyone online in the chat group received Li Xiaoyao's online reminder.

"Ding! Group member Li Xiaoyao goes online."

Yan LINGJI: "Li Xiaoyao is online again! Li Xiaoyao, we are discussing whether something big has happened in your world."

Bumblebee: "I bet a dime. Even the sword Saint came forward. Something terrible must have happened."

Li Xiaoyao: "I think it should be a big event, but it's a little strange. We all don't know."

Mei Changsu: "even the swordsman can't figure out what's going on? Hearing Li Xiaoyao say so, Su is more and more interested."

Sea King: "Li Xiaoyao, stop the ink. Tell us what it is."

Li Xiaoyao repeated what the sword Saint said to him to everyone in the group.

This immediately aroused crazy discussion in the group.

Sonic sonic sonic: "Xu Changqing went to the heaven fifty years ago, and the boundary stone of the heaven in Shushan failed in the same year. How can there be such a coincidence in the world? It has absolutely something to do with Xu Changqing!"

Prophet: "the problem of worshipping the moon sect leader has just been solved. Unexpectedly, new things are going to happen. Li Xiaoyao's world is also so restless."

Yan LINGJI: "now we are basically sure that Xu Changqing's departure 50 years ago has something to do with the failure of the boundary stone of Shu mountain."

Yan LINGJI: "so now the problem comes. Fifty years later, the boundary stone suddenly reacts. Is this also related to Xu Changqing?"

Mei Changsu: "if it is still related to Xu Changqing 50 years later, it shows that the upcoming events in Li Xiaoyao's world began to brewing 50 years ago!"

Li Xiaoyao: "anyway, I'm dizzy now. I don't know the situation at all. There are too few clues. It's hard to speculate!"

Li Xiaoyao: "but there are so many capable people in the group. It's better than me. I don't know if you have any clue now?"

Sonic sonic sonic: "there are too few clues to analyze! Except that Xu Changqing went to the heaven 50 years ago and was related to the failure of boundary stones, any other conclusions are somewhat far fetched!"

Hai Wang: "I have an idea! You see, since Li Xiaoyao's world is on Mr. Xu's timeline 50 years later, Mr. Xu on that timeline must also be in the chat group."

Hai Wang: "and now, Mr. Xu is in the group... Doesn't that mean that Mr. Xu is in both time lines and in the chat group at the same time?"

Haiwang: "so, is it possible for Mr. Xu now to have a chat with Mr. Xu in the future? Ask clearly?"

Sea King's words brightened the eyes of many people in the group.

This idea is very bold, but it sounds reasonable.

Fifty years later, will Xu Changqing still be in the chat group?

No doubt, of course!

So, can we send a message to him 50 years later and 50 years ago?

Yan LINGJI: "I have to say that the sea king was able to come up with such a way, which surprised me a little."

Panther: "hahaha, yanlingji, your implication is that Haiwang's IQ is not good? Hahaha! Sorry, Haiwang, I can't help laughing."

Sea King: "hehe, I was not used to thinking about some complex things. Just now, I was inspired by a film called time and space frequency."

Li Xiaoyao: "Haiwang, you are a genius. This method must work! Ha ha, it's interesting to think about yourself 50 years later and contact yourself 50 years ago."

Mei Changsu: "Su thinks it should be impossible. How will Mr. Xu send a message to himself 50 years later?"

Mei Changsu: "we all know the interface and use method of chat group. We can't do this at all!"
