Early morning on September 9th.

A gentle breeze blows across the streets, as if to prove that the city has begun to cool down. It's not cool to say it's cool, but at least it's goodbye to the unbearable heat of July and August.

When Cheng Yun got up, he was still feeling that the air was burning in September in previous years, and it was much cooler this year, and he even stood on the balcony naked, blowing the wind for a while. But when he washed up and got dressed, he pushed the door out, only to see the old man standing outside his door, dressed in the same suit he had come in—

It was an ordinary cloth robe that I didn't know how long it had been wearing, and the flower ornaments on it were no longer visible, and there were two more patches than when Cheng Yun first saw it. Maybe the old man didn't need to wash it with water, but he couldn't avoid it being exposed to the wind and the sun, so it was still decolored and white as if it had been washed many times, and it was known at a glance that it was some years old. But Cheng Yun still felt that this simple cloth robe without ornaments was the best match for the old man. In his dream, he saw the old master wearing this suit, maybe this had some unusual meaning to him, or maybe it was because he hadn't returned to his own world for a long time during time travel, and Cheng Yun didn't ask much.

The old man held the staff in his hand, which was about the height of his body, and the crystal ball at the top of the staff reflected the scene in the corridor and his slightly wrinkled face and gray hair.

People came and went in the next room one after another, but they didn't seem to see him at all, and they didn't cast a trace of surprise.

"Cheng Yun. The old master called his name, his expression was as kind as ever, and his voice was so gentle that people couldn't help but want to get close, "I'm here to say goodbye to you." ”

"Are you leaving today?" Cheng Yun was stunned.

"Yes. The old master smiled and nodded, and at the same time stretched out his hand to him, and spread it out, revealing several triangular wooden pendants strung with black rope in the palm of his hand, each with a different strange pattern on it, "This is the souvenir I brought back to you from this trip, you can choose for yourself." ”

Cheng Yun took the pendants from his palm in a daze, if he remembered correctly, the old master should have been traveling in space for the past few days, so ...... Is this a souvenir from an extraterrestrial civilization?

He put it away, didn't say much, and said directly: "Do you want to talk to a few of them?"

"No need. The old man shook his head and did not hesitate, "If they ask too much, it may cause you trouble." ”

"Only Cheng Yan will ask vigorously, Yu Dian's character probably won't ask more. Cheng Yun said, "If Cheng Yan asks, just leave it to me to deal with, that girl is very easy to fool." ”

The old master still shook his head: "Let's go." ”

"Okay. Cheng Yun held the pendants and walked to the stairwell between the third and second floors, "Originally, I bought you two sets of robes similar to this kind of robe on the Internet a few days ago, but it may take a few days to arrive." ”

The old master seemed to be a little touched when he heard this, but he didn't seem to have it. His expression seemed to be calm except for a smile.

Cheng Yun pushed open the door, and the two walked into the node space.

In this empty place, which seemed to be nothing, the old master stopped again, turned to look at Cheng Yun, and actually reached out to take the crystal ball from the staff and handed it to him.

"This Crystal of Truth was acquired in my hometown, and it is not very precious, but it is still useful. I would like to leave it in this place. The crystal ball emitted a faint glow, reflecting the deep tranquility of the old man's eyes like a sea of stars, "I think you need it more than I do." ”

"How can this work!" Cheng Yun hurriedly frowned, "This is too precious!

The old man didn't know that he had already roughly browsed the old man's life in that world in his dream, so this lie of 'it is not very precious' would never deceive Cheng Yun.

In fact, this True Knowledge Crystal has been with the Old Master since he stood at the pinnacle of his original world. It has been hundreds of years since he traveled through time and space, recorded the truth, witnessed every step he walked, every person he knew, every culture and knowledge he came into contact with, and every spell he cast.

Not to mention the value of such a large True Knowing Crystal itself, its significance to the old master is also incomparable.

There are even rumors in the world of the old master that this crystal of true knowledge records all the wisdom of the old master's life, and getting it is equivalent to getting the inheritance of the old master. Of course, Cheng Yun knew that this was most likely a rumor, just like 'nutrition is all in the soup', but this crystal was a very well-known and very valuable thing before it became an ornament on the old master's staff.

From a small point of view, it can help a mage clear himself and maintain his true heart, to say a little bigger, it can spy on other people's thoughts, and it can also spy on pictures thousands of miles away, and even bigger, it can help a mage better spy on the truth of the world, even if it is just to cast a spell, it has a very big gain on a mage!

The old man looked at his expression, and after a little thought, he seemed to understand.

I saw him let go of his hand, and the crystal ball was still floating in the air: "Actually, this True Knowing Crystal has no effect on me, and I haven't used its own power for hundreds of years, you are too nervous." ”

"It's true that it's been with me for a long time, and it's hard for me to let go of it. The old master smiled before continuing, "But I also know that maybe it won't be a few decades before I return to my roots, and what are you going to do with it for me then? Bring this Crystal of Truth to my grave for future generations to remember? Or donate it to the museum of my world and put it in a cold glass case for exhibition? ”

"But......" Cheng Yun hesitated, "it could have a better home." You're just trying to convince me. ”

"I think it's a good idea to leave it here, otherwise how would you solve the problem of the time traveler who came here and you don't understand the language?"

......Of course, Cheng Yun knew this, and he also knew that this crystal could solve this problem for him.

"It's also a memorial. The old master said, his eyes narrowed slightly, "I haven't felt this kind of warmth for a long time, whether it's you, or the little girl at the front desk, or your sister, or even the heroine, it makes me feel very warm." You're young, and you don't know how important it is for an older person. ”

"Maybe I'll come back later, and if you already have another solution to this problem, I'll take it back. ”

When Cheng Yun heard this, he stopped twisting, and nodded, "Okay, then thank you for bothering." ”

The old master smiled, waved his hand, turned around, and took out the scroll at the same time: "I'm leaving." ”

Cheng Yun stood behind him and looked at his back, and said, "If you want to come back, we are still waiting for you here." ”

The old master smiled lightly, did not answer again, lowered his head and silently recited the incantation.

I saw that the corners of his robe gradually flew up, and countless runes began to fly out of his body, rapidly rotating around him. In the blink of an eye, the runes seemed to be overwhelming, and there was no edge in sight.

When the old master stopped chanting, the entire space seemed to be filled with a huge amount of energy, and the mist on the light ball of the space-time node also rippled.

Cheng Yun calmed down and controlled the node to let go of the channel.

Finally, the old mage glanced back at him, his face a little blurred under the halo of runes and space-time nodes. In the next moment, he stepped into the ball of light.

Suddenly—

It's all gone!

Once again, the node space is empty and silent, as it has been since time immemorial.

Cheng Yun's heart was also empty, he glanced at the crystal ball that was still floating in the node space, raised his hand and looked at the pendants, and sighed.

"Alas. ”

As soon as the voice fell, the crystal ball suddenly emitted a burst of ghostly light, and the entire node space suddenly changed.

The feet are no longer empty, but have become tiled floors. With a ceiling overhead and whitewashed walls on all sides, the entire node space seems to be transformed into a small room.

Cheng Yun was stunned for a moment.

Isn't this room the same storage room it used to be? It's exactly the same as it used to be a node space!

But the crystal ball and the Void of Yin Maiden made the arrow still float in the air, and he still had a strong connection to the node space. Everything doesn't seem to have changed, but I'm dazzled.

Cheng Yun couldn't help but reach out and touch the ground and wall, there was a cold and hard touch in his palm, and there was a trembling sound when he knocked it, which was exactly the same as the real thing.

Just as he began to think about it, the crystal ball flashed again, and the storage room was empty again.

Cheng Yun was stunned for a moment, and then understood.

He couldn't help but sigh again.

"Thank you. He poked the crystal ball with his fingertips, opened the door casually, and walked out.

When Cheng Yun went down to the front desk, Cheng Yan, Yu Dianxiao and Yin Nuxia were all sitting on the sofa around the coffee table. There was breakfast on the coffee table, a courier wrapper box and a mobile phone case, and Cheng Yan was holding her new mobile phone to put the old card in. And the little girl Yu also took Cheng Yan's old mobile phone and clumsily loaded it into it, and Yin Nuxia watched it with a blank eye, but she couldn't understand it.

"The boss came down. The little girl looked up at Cheng Yun and whispered, "It just so happened that Cheng Yan bought breakfast." ”

Cheng Yan also looked up at Cheng Yun and said, "Uncle Kun, tell him to come down and have breakfast together." ”

Yin Nuxia reluctantly glanced at the mobile phone in Yu Dian's hand, got up and said, "I'll call him." ”

"No need. Cheng Yun said, put the pendants on the glass coffee table, and said, "The master has already left, this is the souvenir he brought us when he went out to investigate last time, one for each person, and he asked me to help hand it over." You choose first, and the rest is mine. ”

"Huh?" Cheng Yan frowned, "Where did you go again?"

"It's not going anywhere this time. Cheng Yun said, "He went back, went home." ”

Cheng Yan and Yu Dian were a little stunned, probably only Yin Nuxia understood the meaning of Cheng Yun's words.

Yu Dian was stunned for a moment, then nodded, hesitated, and asked in a low voice: "Will he come back in the future?"

"Maybe, maybe not. ”

"Has he returned to Jizhou?" Yu Dian then asked.

Cheng Yun was stunned, and then smiled self-deprecatingly, it seems that he made a mistake.

"I guess so. He said.
