() After the history of Tullman, the teacher knocked on the blackboard.

"This is the whole story, you don't need to care too much, you just need to remember that Tuleman was the first person in the world to discover the energy of the source stone, and that's enough, and the exam will only test this."

There was a sparse sound below.

"Got it."

.....

After the teacher finished speaking, Xia Feng sat down and pondered for a long time.

This person who lost his right eye is obviously more reliable than the shepherd genius awakening, but this reliability is only relative.

If the latter is true, the outrageous degree is not much less.

The biggest question is, why did the stranger who lost his right eye know that the source stone was the lifeblood of the world when the world was still in the primitive stage?

If that person is the River Styx, it is not quite right, because he has seen the River Styx, and he has not lost an eye.

And Styx didn't necessarily know the secrets of the Source Stone at that time.

....

After class, seeing that Xia Feng was still sitting in a daze, Di Pai called him.

"Xia Feng, class is over, let's go to the cafeteria to eat."

Summer Breeze came back to his senses.

"Oh, let's go."

Because of the unpleasantness that happened in the Royal No. 1 restaurant last time, this time Piedi didn't go to death, so he had to go to the big canteen with a lot of people to eat, and in desperation, Xia Feng, who was not bad for money, could only accompany him to squeeze the canteen.

.....

A few days later,Xia Feng returned to a peaceful school life.。

In addition to attending classes, his first task is to wait for the arrival of Silver Ash, and secondly, he is also looking for people to work with among the students of the academy as much as possible.

The Karan trade was rich and wealthy, but Xia Feng could not hang himself from a tree until he had personally seen Silver Ash and ascertained his position and attitude.

To put it simply, he knew Silver Ash, but Silver Gray didn't know him, and he was just a stranger to Silver Ash.

...

Except for the first day back at the academy and after Pydi went to the big cafeteria, every day after that, at noon, Xia Feng would go to the Royal No. 1 Restaurant, which was specially prepared for the big shots, because only in this kind of place could he meet the people he wanted to meet.

One day, Xia Feng met a familiar person in the Royal No. 1 Restaurant, of course, he didn't see it with his own eyes, but he just happened to hear that person's friend call her name, Lin Yuxia.

Lin Yuxia is the youngest daughter of the Rat King, because of the previous incident in Longmen, she was also invited by Nanfeng to the barbecue restaurant to drink tea, although the process was easy and pleasant, but Xia Feng always felt a little embarrassed.

A glass of juice was placed on Lin Yuxia's table.

"Please."

Lin Yuxia raised her head, unlike the Rat King, in addition to the round ears like a mouse, Lin Yuxia was very long, and her big eyes were very smart.

Lin Yuxia stared at Xia Feng.

"Who you are, I don't know you."

Xia Feng scratched his face.

"That.... My name is Xia Feng, I'm sorry about the previous incident. ”

Lin Yuxia frowned.

"You're Xia Feng?"

"Exactly down there."

"It doesn't look like much."

“......”

Lin Yuxia didn't have anything to say to him, and this matter was in the past.

....

Noon one day.

Xia Feng met a lady in the restaurant who seemed to be able to cooperate.

This person was introduced to him by Senior Sister Grisha, who is also the daughter of General Gleason.

Xia Feng sat at the dining table, looked at the girl opposite who had a noble temperament as if she was a member of the Victorian royal family, and said loudly.

"You're Miss Ceylon?"

Ceylon wears a white top hat and a long blue and white dress.

Picking up the black tea on the table and taking a sip, she said elegantly.

"I'm Ceylon, and my father is the mayor of Xista City, I don't know what Xia Feng wants to cooperate with me?"

Xia Feng didn't know Ceylon before, but he had studied in geography class in Source Stone, an independent city-state on the west coast of Colombia that was not under the jurisdiction of any country.

The concept of independent city-states is not uncommon in the world of Terra, as these self-contained large cities are not attached to large powers due to certain historical factors, and there are many independent city-states like Shista in history.

However, unlike other independent city-states, the Tidal Tower is not a mobile city, and its development depends on a nearby volcano.

Today, although there are still many independent cities in Terra, their leaders have realized that cities alone cannot compete with the state, and in recent years, many independent cities have taken the initiative to surrender to neighboring countries.

To this day, the city of Tidesta is not owned by any country, because the ore produced from the volcano near Tidesta will give it all the resources to develop independently.

......

Hei Yu is now in urgent need of raw materials for source stone processing, as long as the price is right, Xia Feng doesn't mind finding a few more suppliers.

Xia Feng took out a report from his coat pocket.

"Miss Ceylon, I don't know if you Xista produces these ingredients, even if it's just one of them."

Taking the report, Ceylon took a quick look at it, then shook his head.

"Sorry, we don't have the things you need."

Xia Feng was depressed, he had at least more than ten kinds of raw materials, and Xista didn't even have one, so what did it live on?

"Miss Ceylon, what do you produce in the Tidesta?"

When it comes to the specialties of his hometown, Ceylon's voice is full of pride.

"We at Tidesta produce the best quality obsidian in the world."

Obsidian, this name Xia Feng has heard of, if I remember correctly, the bracelet that Nancy was clamoring to buy last time was made of obsidian, and the price of a broken bracelet is more expensive than gold.

But in addition to being expensive, Xia Feng really doesn't know much about obsidian.

"Miss Ceylon, you speak of this obsidian..... Is it awesome? ”

Ceylon put down the teacup.

"Obsidian is a rare mineral formed in volcanic areas, and in today's world, I am afraid that only Tista will have a stable production environment."

Ceylon said it was very powerful, but Xia Feng didn't think it was very powerful.

"So, what's the use of obsidian?"

"Obsidian is a very, very precious ore, even more precious than the source stone in terms of quantity and rarity."

Xia Feng looked at Ceylon with a bewildered expression.

"You said obsidian..... Can you eat it? ”

"How do you eat stones?"

"Can that be used as energy?"

"How do you use stones as energy?"

"Can that be used as a raw material?"

"It's so precious, how can it be used as a raw material?"

Xia Feng's whole body was about to crack.

"Sister, so, what's the use of it?"

Ceylon didn't care about Xia Feng's repeated questioning, and she twitched her cuffs elegantly.

On the wrist, there is a string of bracelets with a shiny black color.

"It's obsidian, it's beautiful."

"Grace ....."

Xia Feng finally understood, it turned out that obsidian is not a matter of whether it is powerful or not, its biggest use is to be beautiful.

......

In a follow-up conversation with Ceylon, Xia Feng learns that obsidian can only be made into accessories, but although it is a vase stone, it is worth enough to promote the development of an independent city.

At the same time, obsidian is said to have another effect, that is, the wearer can slightly inhibit ore disease, but this statement has not been confirmed by the scientific community, to put it bluntly, just like the jade seller said that wearing jade jewelry can prevent cancer.

...

After talking for a long time, Ceylon's family turned out to be a jewelry tycoon.

"Classmate Xia Feng, I heard that your family is a chamber of commerce, do you need to buy a batch of obsidian from our Xista? As an alumnus, I can give you the lowest price. ”

Xia Feng sighed.

"Okay, let's have a batch, it just so happens that an old friend of mine is planning to open a small handicraft workshop."
