The buyer was a middle-aged man who looked to be in his mid-forties, wearing a gold-rimmed glasses and meticulously combed hair.

Seeing that the young man in front of him understood the true value of this Five Thunder Order, he could only sigh and no longer reluctantly.

It's a shame...... It's a step too late!

He clasped his fists and said solemnly: "It's my clumsiness, it turns out to be a peer, disrespectful and disrespectful!"

"You're welcome!" Jiang Yuanjin returned the salute, put away the Five Thunder Order, turned to Zhou Zhilan and said, "Then let's go." ”

Zhou Zhilan couldn't suppress the excitement in her heart, she originally thought that Jiang Yuanjin didn't understand these people's sophistication and was cheated by the stall owner.

But I didn't expect it to be Jiang Yuanjin's amazing eyesight and pick up a big leak.

Something bought for 3,000 yuan can be worth more than a million - this speed of making money is simply terrifying.

"Little master stays ......" The stall owner hesitated for a moment, but finally shouted.

Jiang Yuanjin turned his head and looked at him calmly.

"Don't worry, I'm not going to regret it, I'm just curious about what is so strange about this Five Thunder Order, it can be worth so much money?" said the stall owner with a sad face.

Three thousand sold, in the blink of an eye, it was worth millions, the difference was like clouds and mud, he was glad that he did not have a heart disease, otherwise he would have to get sick.

The old customers sneered in their hearts, it's useless if you just want to regret it, the money and goods are different, do you still want to be hard guns?

However, they were also very curious about this Five Thunder Order, why this ordinary-looking wooden card was worth so much money!

Since they sincerely asked for advice, Jiang Yuanjin did not hide it, and said with a smile: "This is not an ordinary jujube ......"

"Does it have anything to do with the black spots on the wooden signs?" asked the stall owner with a frown.

Jiang Yuanjin nodded and continued: "Well, what do you think it looks like if you look closely at the black markings?"

Zhou Zhilan looked at it carefully, and suddenly said with a flash of inspiration: "It's like a lightning ......."

Jiang Yuanjin glanced at Zhou Zhilan with a smile, this girl's insight is really amazing.

"That's right, the material of this Five Thunder Orders is a piece of lightning striking jujube wood, that is, the jujube wood was formed after being struck by lightning. Jiang Yuanjin said.

The stall owners were all confused.

Lightning strikes jujube ...... I've never heard of this thing!

"Lightning strike jujube wood can be said to be the most suitable material for refining magic weapons in Taoist Xuanmen spells...... In many classics such as "Ten Thousand Laws Return to the Sect", "Dao Fa Huiyuan" and "Yun Ji Seven Signs", lightning strike jujube wood is used as the first holy wood for making magic weapons, and this five thunder orders are made of a hundred years of lightning strike jujube wood. Jiang Yuanjin explained.

Only then did everyone realize that this wooden plaque with black spots was not the waste wood they imagined, but the most suitable lightning strike jujube wood for refining......

"Then why is lightning striking jujube wood the most suitable for refining magic weapons, is there something special about this?" the stall owner continued.

Now that it has been completed, it is useless to regret and feel distressed, what he wants is to increase his knowledge, and he will not miss the treasure again in the future...... Perhaps, it can also be used to fool others?

"Heavenly thunder is the natural qi of heaven and earth, and there are many elves attached to the hundred-year-old jujube wood.

When the elves cross the tribulation, they will often attract heavenly thunder and burn wood, because jujube wood can store the qi of heavenly thunder and then form the first holy tree of the Daomen - lightning strike jujube wood......"

Jiang Yuanjin explained, and everyone listened attentively, unwilling to miss a word.

If there was no explanation from this young man, they outsiders would not be able to figure it out even if they pondered it for a hundred years.

"Lightning strikes jujube wood is the essence of heaven and earth, yin and yang, and the essence of the five elements.

The memory of Tiangang righteousness, there are also elves and soldiers and horses, with the luck of elves, wearing it can not only resist negative energy and evil qi close to the body, but also bring auspiciousness and luck.

And the thunder is also a catastrophe, lightning strikes jujube wood, through lightning strikes, the energy of thunder and lightning is concentrated in the jujube wood, containing the power of divine punishment, which can be punished and evil...... Jiang Yuanjin said.

"I see, it's really a long experience!"

"When you hear it, it's an insider!

"Lao Xu, you don't lose money selling these five thunder orders, you have learned so much knowledge, hahaha. ”

The crowd burst into laughter.

"you!" scolded the stall owner with a dark face, he was not over at this time, how could he have the urge to hit someone......

Jiang Yuanjin said something profound, and they didn't understand it very well, but this did not hinder their admiration and respect in the slightest.

To have such in-depth research in this field that ordinary people are impossible to know, this young man is not an ordinary person!

Everyone looked at Jiang Yuanjin with admiration, but the stall owner had a momentum to break the casserole and ask the end.

This loss has also been eaten, and it is not too much to increase knowledge, right?

"Then how to distinguish the authenticity of this lightning strike jujube wood, just look at the black lines on the jujube wood?"

Jiang Yuanjin was in a good mood, but he was also happy to say a few more words to them.

If it were him to judge, he wouldn't even have to open the Sky Eye Pass, he would know it by touching it, but ordinary people couldn't do this.

"This is one of the aspects, but Thunder Pattern needs a very senior master to distinguish the real from the fake, and there is another simple method...... Jiang Yuanjin continued.

Everyone listened with bated breath, this is the most important thing, and even the buyers, who had been silent before, looked at Jiang Yuanjin intently.

He can see that if this young man is either a famous teacher, he has a deep family history, and he is by no means an ordinary person.

He had only taken a fancy to this Five Thunder Order before because he had heard of lightning striking jujube wood and had seen it, nothing more.

You must not be like this teenager who explains cause and effect so thoroughly......

"That is to draw a basin of water, wait for the level to calm down, gently put the thunder split jujube wood into the water, and then you will see that the thunder split jujube wood can automatically rotate or move along ......the container," Jiang Yuanjin continued.

"So amazing...... It's worthy of being a Daomen Divine Tree!"

"yes, it's amazing, it spins automatically!"

Everyone sighed with emotion, if it wasn't too abrupt, they even wanted to ask Jiang Yuanjin to use the five thunder orders in their hands to demonstrate.

But Jiang Yuanjin shook his head with a smile: "This miracle has nothing to do with it, but it can be explained by science......

Everyone looked at Jiang Yuanjin suspiciously, how could it be related to science again!

"The reason why this happens is that the water in the tree will be quickly evaporated by the high temperature, and the air volume will expand rapidly, thus forming various microwave holes

These holes can enter the water because they are unevenly distributed, and when they are put into the water, the force of their water absorption is not balanced, and when the force changes, the phenomenon of rotating motion of the wood will be formed...... "Jiang Yuanjin explained.

And these are all the knowledge he has learned from various ancient books in the more than ten years he has followed his master.

He has a strong chest and extremely high qualifications, and the knowledge in these ancient books is unforgettable...... Even the system has given an assessment of the primary appraisal skills, and it is conceivable that he is talented in this area.

Everyone was even more stunned when they heard this, and couldn't help but be impressed - this young man's knowledge is really too profound!

"Thank you for the teaching, I really took it today!" the stall owner clasped his fists and saluted, happy and convinced.

"Thank you, little master...... Today is really a long knowledge!"

"Thank you, little master, for teaching, I don't know if you are free today, little old man, I am the east, please have a meal......"
