Martial Arts: Breaking the thunder with a snap of a finger, do you think you are a doctor?

After hearing Shui Yunji's words, Ye Chen couldn't help but chuckle.

It can only be said that the Tang Dynasty Academy is indeed too low-key!

Even Shui Yunji, a local force in the Tang Dynasty, has no idea about the situation of the Tang Dynasty Academy.

Seeing Ye Chen's smile, Shui Yunji said with a little doubt:

"Sir, but what's wrong with what I said just now?"

"The Tang Dynasty Academy has always had only one teacher."

Ye Chen said in a calm voice.

After hearing Ye Chen's words, Shui Yunji was stunned for a moment, and after savoring the meaning of Ye Chen's words, she opened her mouth in surprise.

"Sir, you... you mean that the teacher of Datang Academy is the one who founded Datang Academy?"

After seeing Ye Chen nod, Shui Yunji said in shock:

"Then this teacher... isn't it already..."

Looking at Shui Yunji's innocent and surprised look at the moment, Ye Chen also found it quite interesting. He smiled and said nothing more.

"Brother Ye, come and see, this stone is so beautiful!"

Huang Rong and Sikong Qianluo gathered in front of a stall of a foreign merchant and waved to Ye Chen.

"Brother Ye, look, this is the first time I have seen this kind of stone, it's so shiny!"

When Ye Chen and his friends came closer, Huang Rong pointed to a shiny stone on the stall and said.

"Yes, it's the first time I have seen it too!"

Sikong Qianluo also spoke.

"This is crystal obsidian."

Hearing Huang Rong's call, Miao Chengtian and several other girls gathered in front of other stalls also came over.

Seeing the stone Huang Rong pointed to, Miao Chengtian spoke.

"Crystal obsidian?"

Seeing the doubts of the girls, Miao Chengtian introduced:

"This crystal obsidian is also a kind of ore buried underground, but we don't have it in the Central Plains. Only the Far West produces this kind of stone."

"When this crystal obsidian first appeared in the world, it attracted many people's pursuit."

"It's just because its texture is extremely hard, even better than copper and iron."

"Many foundry masters think that this may be a good casting material."

"But after experiments, everyone found that although this crystal obsidian is extremely hard, it is malleable. The properties of this crystal are very poor, and it will turn into dust under high-temperature smelting, and it cannot be used to cast objects at all. "

"And this crystal stone has very poor conductivity for true energy. As long as the internal force is poured into it, it will turn into powder. It is not suitable for use as a weapon at all, and can only be used as an ornamental item."

"Therefore, the value of this crystal stone quickly fell, and no one was interested in it."

"In addition, it is very difficult to mine and it is extremely difficult to polish. Later, fewer and fewer people mined it, which made it somewhat rare."

While Miao Chengtian was talking, Ye Chen also saw this so-called crystal stone.

Huang Rong and the others had never seen it, but Ye Chen was quite familiar with it, because it was the diamond from Ye Chen's previous life.

"Is that so."

After listening to Miao Chengtian's introduction, Huang Rong and the others immediately lost interest in the crystal stone and turned to run to other stalls.

...

At the same time, just when Ye Chen and the others had just entered the Luoyang Imperial City.

"Hmm?"

Outside the Imperial City, on the second floor of the Tang Academy, the Master, who was originally fishing leisurely, suddenly changed his expression and looked up in the direction of the Imperial City.

"Master?"

Seeing the change in the Master's expression, Li Manman, who was following the Master, asked curiously.

As the person who has followed the Master for the longest time among all the Master's disciples, in Li Manman's heart, the Master's image has always been unfathomable, omnipotent, and a peerless master who does not change his face even when Mount Tai collapses in front of him!

But in recent days, Li Manman has seen Master's inappropriate expression many times.

Especially the last time, Master's expression and language at that time were clearly telling his last words.

Li Manman has always been very curious about this.

What kind of existence can make Master, who is almost omnipotent in his mind, have such emotional changes?

"Manman, pack up and accompany me to see someone."

Master spoke slowly, with a hint of expectation in his tone.

"Yes, Master."

Li Manman immediately responded.

...

Ye Chen and his group walked around the entire Zhuque Street, and Huang Rong and the others bought a lot of things.

Seeing that it was getting late, everyone had a good time shopping, so they prepared to go back.

Just as Ye Chen and his friends were about to walk out of Zhuque Street, a carriage slowly drove over from the opposite side and stopped in front of them.

The driver of the carriage was a man dressed as a scholar.

"Excuse me, friends!"

The man stopped the carriage, got off and bowed to Ye Chen and others, then came to Sang Sang beside Ye Chen and said slowly:

"Miss, I like the umbrella in your hand. I want to exchange it with you for this book in my hand. Is that okay?"

"No!"

Sang Sang refused without even thinking.

"Miss, don't rush to refuse. My book is not ordinary and will be of great use to you."

After being rejected by Sang Sang, the scholar was not angry and continued to speak slowly.

As he spoke, he spread out the rolled book in his hand. The cover was very clean, with only a big "Ming" character written on it.

At this moment, Ah Qing, Li Hanyi and others were immediately attracted by the book in the hands of the scholar.

Although it was just an ordinary book on the surface, Li Hanyi and others could feel that it contained infinite light and power, which was very mysterious.

Li Hanyi and others were very surprised by the behavior of this scholar.They were all very curious.

The scroll in the scholar's hand was obviously not an ordinary thing.

As for the big black umbrella in Sangsang's hand, Li Hanyi and the others did not see anything unusual. Before, they only thought that the big black umbrella was a gift from Ye Chen to Sangsang, so Sangsang would carry it with him every day and was reluctant to let it go.

Now it seems that the origin of this big black umbrella is not simple.

"Master!"

Looking at the scroll in the scholar's hand, Sangsang pouted and ignored it, but turned her head to look at Ye Chen.

Obviously, the decision was given to Ye Chen.

"If this young master doesn't believe it, you can take a look at this scroll first, how about it?"

The scholar also looked at Ye Chen and said with a smile.

Then he handed the book to Ye Chen.

Ye Chen raised his hand and stroked Sang Sang's hair, and said in a calm voice:

"Although this heavenly book "Ming Zi Juan" is good, it is still not enough to exchange it for a corner of the dark night."
