The value of the Warcraft Crystal Core and the Energy Crystal Stone is equivalent. The former was dug out of the Warcraft's brain and gathered most of the elemental power of the Warcraft. The latter is an ore product and only appears in areas with abundant elemental energy, with very little output.

For magicians, the most common use of the magical crystal core is to make the head of the magical staff. It is also often used in some alchemy experiments. It has auxiliary and enhancement effects on knights and magicians, but the effect is perfect and lasting.

Energy crystals are generally used for charging large magical instruments or assisting in impacts at a higher level, such as floating ships or space fortresses docked outside the plane, and their main kinetic energy is provided by the energy crystals.

Locke has just been promoted to a higher-level attendant, and his level of Dou Qi has not reached his limit. Now it is time to use energy crystals, so how can he adopt this trading method?

Most of the knights who came to the Santa Tower to trade were paid for the Warcraft Crystal Core. The white-bearded magician was not surprised and took the Warcraft Crystal Core handed over by Locke.

With just one sweep of mental power, the white-bearded magician had already distinguished the authenticity.

"Please wait."

The white-bearded magician in the window stood up and left for a while. Not long after, he appeared in the window again. There were four rolled dark blue scrolls in his hand.

"Your stuff, knight." The magician handed over the scroll.

Locke didn't look at it, and directly put the scroll into the space ring. He felt that such a large exchange would not cheat him.

"Are there any other products?" the white-bearded magician asked with a smile. The transaction volume of the six high-level magic crystals was also quite a lot in the end.

"No more, I will come again if there is. "Locke stood up and said goodbye. It was not that he didn't want to buy anything, but that he didn't plan to buy it here because the price was too expensive.

"Okay, knight, please confirm my window number next time you come again, and I wish you a happy!" The old man with white beard pointed to the number 17 above his window and said with a smile.

"I will." Locke nodded.

After leaving the Santa Exchange, Locke did not rush to find his next goal, but instead found a restaurant and sat down for a meal.

Not bad, restaurants, and there are many such shops in the trading area outside Santa Tower.

Not only magicians and knights exist on this island, but a certain number of ordinary people are also living here.

Some of them worked as slaves and odd jobs in the Santa Cathedral Academy, and some opened stores in the trading area outside the Santa Cathedral. Their main services were magicians and knights.

This is their only way to make a living, because neither the giant forest inside the island nor the endless sea outside the island are accessible to ordinary people.

After drinking and eating, Locke threw down a low-level monster crystal core on the table and said, "Don't look for it!" He left amid the waiter's thanks.

These ordinary people also have their own currency system, but unfortunately gold coins are not applicable here, so Locke can only pay for the money with the Warcraft Crystal Core.

With half a day left, no more or less, Locke started to wander around in the trading area.

His idea was to buy another space ring. The one he is currently using was given to him by Angelina before. As his strength improves, his family's wealth becomes more and more abundant, and the internal space of this space ring is no longer enough.

In addition, this is a female ring, and when Locke took it out to pick up something, it was quite embarrassing to be seen.

The trading hall he just left must also sell space rings, and it must be the masterpiece of a master in the Santa Tower, but he doesn't want to spend that in vain.

As long as it can be used, Locke doesn’t have much requirements.

Walking around the trading area, Locke found what he wanted to buy.

In front of a stall, there were all kinds of magic equipment, and many knights gathered here, and it seemed that there were many good things.

The stall owner is a middle-aged male magician. From the outside, he looks rather dull, and looks like a dead house among magicians.

These magical equipment should be his works. Although it looks rough, it seems to be practical.

"How much does this gravity bracelet cost?" asked a man with dark skin and two meters tall. He was not wearing knight's armor, but with his muscles, he could probably withstand ordinary sword attacks.

"Five intermediate crystal cores." The middle-aged magician cherishes his words like gold, and after speaking, he remained silent.

"I bought it!" The dark man threw five intermediate crystal cores onto the stall, picked up the gray gravity bracelet, and played with it with it with love.

Locke has seen such a gravity bracelet in the practice room of the Knights Hall. The small bracelet can be adjusted by the user and increase the weight from 100 to 500 kilograms. Whether it is practiced in daily life or suddenly used in battle, it is a good piece of equipment.

Judging from the appearance of this bracelet, it is more than one level worse than the one in the Knights Hall, and the upper limit of the weight increase is also a little lower, about 400 kilograms.

But the most important thing is that the price is really cheap. Locke couldn't help but complain that if he was in the trading hall just now, this gravity bracelet would probably have the price of a high-level crystal core.

The dark man took his harvest and happily turned around and squeezed out of the crowd.

"If it is broken, you can have a warranty!" The middle-aged magician seemed to remember something, and stood up and shouted to the dark man who had already squeezed out of the crowd.

No one answered him, but he stretched out his two black hands from behind the crowd and waved them. The dark man said he knew.

In addition to the gravity bracelet, there are many good things on the middle-aged magician's stall. A knight who has already picked up good items came forward to ask about the price.

"I need a space ring. Do you have any recommendations?" When it was Rock's turn, Rock asked the middle-aged magician.

"This, this, and this are all good." The middle-aged magician picked out three rings of various shapes from the stall and handed them to Locke.

Each ring is carved with mysterious magic patterns, and a faint magic power surges. Locke knows that these three rings are larger than the one he uses now.

"Can you tell me the difference?" Rock asked.

The middle-aged magician paused first, took three space rings and said, "The internal space of this one is 50 cubic meters, with a load-bearing two tons, this one has an internal space of 100 cubic meters, with a load-bearing three tons, and this one has an internal space of 150 cubic meters, with a load-bearing four tons."

The three space rings were all made by him, so the magician opened his mouth without thinking. The only difference is the internal space and load-bearing ability.
