The morning of the empire was particularly lively, the sun had just risen, and the streets were already full of traffic and people.

After withdrawing from the trading market, Li Yunyang didn't sleep again, but went out directly to do the morning class, and after two weeks of circulating the inhaled aura in his body, he sank into the sea of people, and when Li Yunyang opened his eyes again, he was already refreshed!

The fatigue is gone, and my mother no longer has to worry about my lack of sleep......

Vivian also got up early in the morning today, presumably last night's unhappy break up also made him fall asleep early, right?

The five of them started shopping in Svenburg early in the morning, because Vivian said he was going to take them to eat the best breakfast in Svenburg, and they lived in the middle of the city, and that place was to the east of the city......

In fact, as soon as he saw Wei Wei'an, Li Yunyang remembered the mysterious person last night, and always felt a little weird, seeing that Wei Wei'an seemed to be in a good mood, Li Yunyang planned to find a time to inquire about the situation in his family, after all, this is a matter, and it has to be done, but Li Yunyang doesn't know anything about Wei Wei'an, the only thing he knows is that he has a bastard brother, and he doesn't know how many brothers they have......

Looking at the vendors coming and going on the street, a cart of grain, and a car of animal skins, Li Yunyang also asked, near the Pirka collar, a pound of grain costs almost 20 silver coins, but in the empire, a pound of grain only costs 90 copper coins!

The price difference was more than twice as much! Li Yunyang's first thought was to come to the empire to buy grain, and then ship it back to Pirka!

But this is not okay, these two fast horses galloped at full speed for almost a month, how long will it take if this is pulled by a carriage? How many mountain and forest bandits will come out to rob the road in the middle is even more unknown, please guard? Are you sure I don't know, but if you count this cost, then it is better to buy it nearby!

In fact, it's right, Li Yunyang can think of such a simple way to make money, how can others not think of it?

"Huh!" As he was walking, Li Yunyang's eyes suddenly fixed on a tall tower not far away, he stopped, his eyes were full of curiosity, and he pointed his hand to Wei Wei'an and asked, "That magic guide pearl is placed on this?"

"Well, there is only this pearl tower in this city. Wei Wei An nodded, and smiled at Li Yunyang: "Want to go and see?"

If such a thing can be erected in the Pierka collar, it should be Dorafeng!

Thinking like this, Li Yunyang was not polite, turned around and walked in the direction of the tower, everyone smiled heartily, and followed.

"This is a formation left over from ancient times, and that is the center of the formation. "Walking into the tower guarded by the soldiers, the group walked up the stairs spiraling up from the inside to the top of the tower, Vivian pointed to the disc engraved with strange symbols in the center of the tower and said: "Every time night falls, the soldiers guarding the tower will add magic crystals to it, and after adding enough magic crystals, the formation will be automatically opened, and the silk thread made by guò with 'flame essence crystal' will inject energy into the one on the top." The Gilt Moon Crystal is a kind of spar that will glow as long as it encounters energy, and the output on the continent is also extremely rare, and the big ones are even rarer. ”

Under Wei Wei'an's explanation, Li Yunyang looked up at the crystal that was supported by a wooden frame to be more than ten meters high from the top of the tower, which was two sizes larger than a basketball, and emitted a colorful light under the sunlight.

"Cool~~" Li Yunyang couldn't help but admire, Li Yunyang naturally understands this principle, this is like a combination of batteries, wires and light bulbs, he just thinks it's incredible, people in this era can actually invent such a magical thing!

"It's good, it's just that this thing is too expensive, not to mention the cost of the cost, this magic crystal consumption alone costs more than 100 gold coins every night!"

"So many?" Li Yunyang was also taken aback, knowing that Li Yunyang's annual income was only 100 gold coins!

"How many magic crystals do you have to consume?" Li Yunyang looked at it and asked.

Wei Wei'an smiled bitterly: "This thing also consumes first-level magic crystals, and other levels can't afford to consume them at all, first-level magic crystals have to consume more than 150 in one night, and second-level magic crystals will consume more than 30, and third-level magic crystals also consume 6-7 pieces!"

In this world, Li Yunyang has been in contact with the magic crystal for the longest time, so he is also very clear about the approximate price of the magic crystal, this level of magic crystal is about 60 silver coins, the second-level magic crystal is almost 5 gold coins, and the market price of the third-level magic crystal is nearly 40 gold coins!

That's right, if you use a first-level magic crystal, it's almost 100 gold coins, but if you want to use a second-level one, it has to be more than 150 gold coins, and a third-level one will directly reach 300 gold coins!

The higher the level of the magic crystal, it does not mean that its energy also goes according to this ratio, and the higher the energy, the higher the price, it will only mean that the price will be doubled, not to mention the fourth or fifth level of the magic crystal.

Li Yunyang curiously took out a first-level magic crystal, stepped forward and put it into the formation, but there was no sign of activation at all, and when he turned around, he saw Wei Wei'an looking at himself and smiling!

"As I said, you have to have enough energy to start it, and if you don't bother to start it, you can add it piece by piece. ”

"Then how many pieces do you want to add to it?" Li Yunyang, a first-level magic crystal, is naturally not lacking, this thing is really a bit like the fuel consumption ratio generated when a car starts and steps on the accelerator!

"I don't know, if you have more spars, you can add them piece by piece. "After all, Vivian didn't personally activate this kind of soldier thing.

"Two pieces. "Three pieces. "Four pieces!"

After reaching the fourth block, this disc-shaped formation suddenly resonated like a flash of light, and in the blink of an eye, this pale yellow light shrouded the main disc, and the magic crystal thrown in it was basically invisible!

I saw that after this layer of light filled the entire disc, it began to slowly spread upwards from the metal wire that fell straight down, and soon this light reached its peak, and when it touched the 'Moon Crystal', the two basketball-sized crystals slowly began to brighten!

After only a while, a dazzling white light was emitted, and Li Yunyang and the others who were stabbing could no longer look up, because they stood close, and this look actually felt that it was as dazzling as the sun in the sky!

"I really didn't expect that this magic crystal nucleus could be used like this in addition to refining weapons!" Li Yunyang's mouth couldn't compare with each other!

"What's more!" Jeff, who was silent on the side, interjected, "In this Marquis City, Duke City, and Imperial City, there are also 'Divine Fury' powered by magic crystals!

"Divine Fury?" Li Yunyang finally has a long understanding this time, this is clearly the high-tech of the cold weapon era!

"Uh-huh!" Jeff's face yearned, but then he lowered again: "It's just that thing, a nobleman above the marquis, doesn't have a chance to go in and watch......"

Soon, the four magic crystals thrown into it were completely gone, and as the beam slowly dimmed, it immediately regained its original appearance, but the four white magic crystals on the disc had turned into a black slag at this moment, shattered like powder!

"Why do you want to make the line so long?" Li Yunyang looked at the deconstruction of the entire device, and his brows couldn't help frowning, since the principle is the same, then the beam of the metal wire will naturally produce something similar to 'resistance', not to mention that this light itself is a kind of energy, and it will naturally be no good if it grows!

"Who wants to do this?" Wei Wei'an also understood what Li Yunyang was talking about, but he might have understood it differently, and said with a wry smile: "This 'Flame Essence Crystal' is also an extremely rare and precious ore on the mainland, and it will cost a thousand gold coins just to build this thin line! It's a pity that this high platform can't be built any higher, and if the wind is stronger, it will fall, and the one on top can only be built with a wooden shelf." ”

Li Yunyang didn't expect this floor, too, it is not easy to build this small tower to a height of more than ten meters with wood, not to mention that there is a staircase inside, which is both beautiful and solid, and the people of this world probably haven't figured it out, right?

"And the Gilding Moon Crystal, just this one, it costs more than a thousand gold coins, and the formation plate is cheaper, like this kind of plate, as long as it is with the noble badge, it can generally cost two hundred gold coins. Vivian then added.

"That means that if you want to build such a thing, you really can't get it without three thousand gold coins?" Li Yunyang estimated, and was also taken aback by the price, but after getting Wei Wei'an's affirmative nod, it was like that......

It's no wonder that there are no ordinary places, just this thing, where can ordinary cities afford to use it! If you can afford it, then you have to be able to afford it! This day will cost 100 gold coins, and a month will cost 3,000 gold coins!

What about that year? What about ten years? What are you kidding! Is this money really picked up?

After seeing it for a long time, he got off the tower, and Li Yunyang didn't forget to look back again, "This thing, if you can really erect one in front of your own mansion, how domineering it must be!"

This trip to the empire really didn't come in vain, at least it made Li Yunyang understand what is called the disparity between the rich and the poor, and what kind of life is worthy!

Deeply condemned, for more than half a year, Li Yunyang asked himself, what have he been doing!

Li Yunyang secretly swore in his heart that after returning this time, he would definitely build his territory into the most luxurious territory in the whole continent! What is it to be well fed and warmly clothed? Lao Tzu wants the people in the entire territory to live in the best, eat the most fragrant, and wear the most fashionable clothes! I envy you?

......

But what Li Yunyang didn't know was that at this moment, in the Pirka territory, his people were suffering a terrible catastrophe......
