"It's... Rare items! ”

Su Yu's eyes lit up.

The rarity of the system has always been extremely valuable.

Let's not talk about Xiaoqinglong, the Chinese totem of the previous life.

Several rare items in front of him are very suitable for Su Yu.

Every time a rare item is opened, Su Yu is looking forward to it unusually.

"I don't know what this rare item is."

Su Yu curiously clicked on the rare items column.

Suddenly, purple brilliance gradually diffused between heaven and earth.

The next moment, a message appeared in front of Su Yu.

"Growing Energy Vein!"

In front of him, an illusory small energy vein appeared.

The energy stones above shimmered brightly.

"Growing energy veins?"

Su Yu was a little puzzled.

"System, introduce."

"Ding, a growth energy vein, can grow with the increase of energy, and is now a primary energy vein, from which the host can obtain ten energy stones every day. There are intermediate, advanced, superb, and legendary levels in the follow-up. ”

"Intermediate energy veins can get a hundred energy stones per day, high-grade energy veins can get a thousand energy stones per day, top-grade energy veins can get 10,000 energy stones per day, and legendary-level can get 100,000 energy stones per day!"

"Primary Energy Veins only exist in the Synthesis Bar System, and when they reach an advanced level, the host can place them anywhere in the real world."

Looking at the introduction of the system, Su Yu's whole person shook instantly.

"This... This is really against the sky! "

Su Yu's heart shook.

It's not that Su Yu hasn't seen the market, but this thing in front of him is really rebellious.

What is an energy vein?

It was something that could produce energy stones, and energy stones were the common currency of the entire Ten Thousand Continents, which could not only be exchanged for many resources, but also used for their own cultivation.

Moreover, near an energy vein, it can even make the surrounding energy more intense, and with the passage of time, it may even form a blessed land cave.

Such a precious thing was actually opened by itself?

Su Yu still has a feeling of dreaming even now.

It's so unreal.

"System, how to upgrade the energy vein?"

Su Yu asked excitedly.

"Ding, from beginner to intermediate, you need ten top-grade star stones, intermediate to advanced, you need one hundred top-grade star stones, high-level to best-grade need a thousand, and legendary-level needs ten thousand."

Looking at the above introduction, Su Yu's heart sank.

The best star stone!

You must know that the best star stones in the entire Ten Thousand Races Continent have only appeared five times, although there are hundreds or even thousands of them every time they appear.

But after so many years, don't talk about Great Xia, even if it is the entire Ten Thousand Races Continent, it will definitely not exceed a thousand.

And in the entire Great Xia, all the best star stones are only about fifty.

Of course, some of the star veins may be able to give birth to the best star stones, but they are all monopolized by the three clans, and Great Xia has no chance to get them.

The only chance I can get is the Qiankun Cave.

But that's not always available.

And this is only to raise the energy vein to the extreme, not to the legendary level.

However, Su Yu is okay, there is no top-grade star stone, but Su Yu can rely on the synthesis column to synthesize.

In the human race, which is extremely scarce in resources, the synthesis bar system is simply an invisible cheating machine for Su Yu.

Resources are not difficult for Su Yu.

As soon as he thought of this, Su Yu's breathing became rapid.

You must know that the energy vein in Leopard City is only a primary energy vein, but after hundreds of years of accumulation, it has accumulated more than 100,000 energy stones.

And this small primary energy vein directly supported the cultivation resources of the entire Leopard City.

It can be seen how important an energy vein is to a race or a city.

It is no exaggeration to say that if Su Yu placed this primary energy vein in Hengcheng, in less than ten years, Hengcheng would definitely be able to become the first city of the human race.

It's only a matter of time before we surpass Kyoto and the Magic City.

Because the most serious problem facing Great Xia now is the lack of resources.

The talents of the human race are very good, as long as the resources are enough, it is only a matter of time before they surpass the ten thousand races.

Su Yu's eyes were blazing as he stared at the illusory energy veins in front of him.

"It's a pity that it has to be upgraded to a high-grade energy vein before it can be realized."

Su Yu shook his head with some pity.

"System, extract energy stones."

Su Yu said to the synthesis bar system.

"Ding, the extraction is successful!"

With a mechanical voice sounding in Su Yu's mind.

In front of Su Yu, ten energy stones were quietly suspended in front of Su Yu's chest.

Su Yu unceremoniously grabbed ten energy stones into his hands.

"By the way, didn't Teacher Li say that when I get better, he will take me to see the teacher?"

Su Yu's eyes lit up.

To be honest, although he apprenticed to the Dragon Slayer King, Su Yu had never seen the Dragon Slayer King's body for so long, and every time he saw it, he was the Dragon Slayer King's doppelganger.

Su Yu cleaned up briefly, and then walked out of the room.

Just after Su Yu walked out of the room, Li Changsheng's figure emerged.

"It's been fixed so quickly?"

Li Changsheng looked at Su Yu, who was healed in front of him, in surprise.

In Li Changsheng's estimation, even if Su Yu's body hid the vitality of the star essence, it would take three or four days.

However, it only took Su Yu two days to completely recover.

With such a rapid speed, Rao is Li Changsheng, the second terrifying existence on the Grandmaster List, was surprised.

Su Yu smiled and said.

"I've recovered, can Mr. Li take me to see the teacher now?"

Li Changsheng nodded and sighed.

"Monster, it's just a monster, in just two days, such a serious injury, it has recovered, it deserves to be the first person in this year's college entrance examination!"

Then, Li Changsheng walked towards the center of Dragon Destroying City, and Su Yu followed.

Along the way, Su Yu saw a lot of soldiers wearing gray armor and black armor passing by.

And every soldier who passed by him would look at him with a scrutinizing gaze.

And the more he walked into the depths, the more he could feel the terrifying energy in the bodies of those soldiers in armor, and even Su Yu saw several generals in silver armor.

Their eyes were the same as the soldiers', full of scrutiny, Su Yu's brows furrowed slightly, looked at Li Changsheng, and said.

"Teacher Li, why do you feel that they look at me a little specially?"

Li Changsheng looked at Su Yu strangely, and then said with a smile.

"You'll know when you see the Dragon Slayer in a moment."
