Yi Nan sighed, "I also heard from those very old teachers, there have always been ice spirit dragon sparrows in the academy before, which I have never seen before. ”

"Are you leaving?" Qin Yunfeng was extremely disappointed in his heart, if there was no here, then he didn't know where to look for it.

"It's okay Yunfeng, after we go out, I'll go to the principal, he will definitely have a way. Yi Nan comforted.

Qin Yunfeng nodded, "Okay, I can't give up anyway." ”

The two looked at each other and smiled, and their feelings gradually warmed up in this vast abandoned library.

After a while, Qin Yunfeng stood up, wanted the painter to be speechless, and walked around the bookshelf to see if there were any books left on the shelf.

Just when Qin Yunfeng came to the opposite side of the gate of the abandoned library, he suddenly stopped.

There were no bookshelves, but a smooth wall with what seemed to be carved into it, but it was now obscured by dust.

"Yinan, you come here to have a look. Qin Yunfeng shouted.

Yi Nan walked over and was surprised when he saw this wall. The walls sink inside, making it difficult to see without paying attention.

Qin Yunfeng stepped forward to wipe the dust off the wall, revealing the words on it.

It seems to be a couplet, but only the upper couplet.

"Odd and even unchanged......" Yi Nan slowly read out the words on the wall, frowning, "What does this mean?"

When Qin Yunfeng saw these words, his expression was suddenly stunned, and then he laughed.

"Yun Feng, what are you laughing at, do you know what this means?" Yi Nan asked.

Qin Yunfeng nodded, stepped forward, took out the long knife behind his back, and with a quick swing, carved a few words on the other side of the wall.

"Symbols look at quadrants?"

Yi Nan was even more puzzled, he didn't know what this meant at all.

Only Qin Yunfeng laughed, this is not a couplet, but the mathematical knowledge that will be learned in junior high school on the earth.

"The odd change does not change, the symbol looks at the quadrant, but it rhymes, but it is not neat at all. Yi Nan said slowly.

"You don't need to be neat," Qin Yunfeng laughed, "Believe me Yinan, these two sentences are a whole sentence!"

As soon as Qin Yunfeng's words fell, the wall suddenly shook at this time, and then slowly flipped over.

"Really...... Really?" Yi Nan's eyes widened, "Yun Feng, how do you know?"

Qin Yunfeng thought about it, he was a person who crossed over from the earth, and it was best not to let others know about this matter.

"It's a secret. ”

Yi Nan rolled his eyes in disgust, and the two slowly walked behind the wall.

As soon as they stepped into the space behind the wall, the scene in front of them suddenly changed, and in the blink of an eye, they came to a place where birds and flowers were singing.

"What is this?" Yi Nan took Qin Yunfeng's hand in surprise.

Qin Yunfeng smiled, "Don't worry, it's okay, this is just an illusion, I'm in the Shenwu Tower, but I've encountered a lot." ”

Holding Qin Yunfeng's hand, Yinan slowly calmed down.

"Young man, I know you and I are from the same place. A figure slowly walked out of the flowers. 000 Literature

It was a kind-looking middle-aged man with a smile on his face and a deep and wise gaze.

"You...... Who is it?" Qin Yunfeng asked excitedly.

"My name is Lu Yi, and I am from Qinglan Province. The man said lightly.

"Qinglan Province, what kind of place is that?" Yi Nanke had never heard of this place, "and...... Lu Yi is the founder of the Shenwu Academy!"

After Qin Yunfeng heard this, he almost burst into tears, Qinglan Province is the name of the earth, and it just so happens that he is also from Qinglan Province!

"I ...... I'm also a ...... from Tsing Lan Province."

"Hahaha, it's really interesting, I didn't expect that after 3,000 years, I would be able to meet a fellow countryman. Lu Yi laughed.

"yes, you...... Is it already dead?" Qin Yunfeng asked.

Lu nodded, "Yes, I have been dead for three thousand years, and what remains here is just a wisp of my remnant soul, if you don't come again, I'm afraid this remnant soul will dissipate." ”

"That's a pity...... Qin Yunfeng muttered.

He wanted to have a confidant and confide, Lu Yi was undoubtedly such a person, but unfortunately, Lu Yi had already died.

The two chatted a lot, which made Yi Nan around her confused, but she listened quietly with a very good acquaintance, and there was obviously some connection between Qin Yunfeng and Lu Yi.

After a long time, Lu Yicai nodded with satisfaction.

"It's so comfortable, I held it for thousands of years when I was alive, and I didn't expect that after I died, I would be able to have someone to talk to. Lu Yi said with a smile.

Qin Yunfeng also nodded, but quickly thought of a question.

"These things are all modern things, when did you come?" Qin Yunfeng hurriedly asked.

Since they are all modern things, and Lu Yi has been dead for three thousand years, it is said that at that time, the earth was still far away.

"In 2018, what about you?"

"Me too. ”

The two looked at each other, since they were both people living at the same time, why was the time difference so far away after crossing over?

"After all, this kind of thing has happened, and time confusion is nothing new, is it?" Lu Yi was very open.

Qin Yunfeng nodded, "That's the same." ”

Neither of them pursued this matter anymore, if Lu Yi was still alive, the two would definitely become very good friends and know each other's secrets.

"I've spent my life looking for a way back, but I can't, so I've left this one behind, and now I'm giving it to you. Lu Yi said lightly, and a metal ball slowly flew towards Qin Yunfeng.

Qin Yunfeng took it, the ball was no more than the size of a fist, and the weight was also very light, and it was engraved with ancient lines, and a desolate and ancient aura came to his face.

"What is this?" Qin Yunfeng was very curious.

"I call it Vientiane, it's a magic weapon that I refined myself, it has a lot of functions, and I believe you can use it correctly. After all, we are fellow countrymen!" Lu Yi laughed, but now that he looked at it, he found that there were some fluctuations around him.

It's like watching TV when there is signal interference, and the picture starts to distort.

"It seems that my time has come," Lu Yi shook his head helplessly, his face still full of smiles, "Let's try to live." ”

After speaking, the scene in front of Qin Yunfeng and the others changed again, and they came to the secret room in the abandoned library underground.

"I actually saw Principal Lu Yi...... I can't believe it!"
