The senior apprentice's movements were very fast, and he rushed back in a hurry, no wonder he was so eager, it was too practical for the things in his hands.

The consumption of spiritual power is small, and it doesn't look at its own attribute affinity, as long as there is a steady stream of magic stones, it can continue to attack, and the range has reached thirty meters, is there anything more practical than this?

This can definitely cause an uproar among apprentices, a senior apprentice without this thing is a dish in front of a junior apprentice, what kind of gadget is this, this is simply an artifact that changes the pattern of apprentices.

"My lord, Lord Leo, I want this thing from you, I want as much as I want. The apprentice hurried up to Leo, waved away the woman who was waiting, and said impatiently, completely forgetting the calm that a businessman should have.

Leo was not surprised by the apprentice's actions, this thing had no effect in the hands of a first-level wizard, but what about the apprentices? if he wanted something in the apprentice colony on the coast, he had to walk sideways.

"Sidrick, it's not the first time we've dealt with each other, forget about the magic stone, let's exchange it for materials, ten ordinary materials, five precious materials, and one precious material. ”

Cedric suddenly woke up from the huge surprise and said with a wry smile: "My lord, how can the apprentice have any good materials, see if you can buy them with magic stones." ”

Leo shook his head and said, "Why do I want so many magic stones, in addition to recovering a little spiritual power, I can't even buy treasure-level materials, so let's exchange them for things." ”

Cedric knew Leo's rules, and he also understood the other party's approach, although he didn't know the specific cost of this thing, but the price was really a bit high, "Lord Leo, the magic stone is not good, can the quantity of materials be reduced a little." ”

Leo thought for a moment and said, "In this way, the number of materials remains the same, but the content of the exchange can be changed." ”

"My lord, what do you want to exchange?" Cedric asked cautiously, he was afraid that something as priceless as knowledge would burst out of the other party's mouth.

"Recipe. No matter what kind of potion recipe it is, you can exchange one for the ordinary level formula, three for the precious level formula, nine for the rare level formula, forty for the rare level formula, and one hundred for the rare level formula. You can tabulate the name of the recipe, and I'll decide which ones to redeem on a case-by-case basis.

In addition, the drawings are the same, whether it is a puppet drawing, or a drawing of experimental equipment, the exchange method of puppet drawings and formulas is the same, the better the experimental equipment, the more the number of exchanges, this can be discussed at that time. Leo said the exchange in an extremely flat tone as if he were talking about ordinary things.

The level of the formula and materials is about the same, the blueprint of the first-level mechanical golem is equivalent to the precious level, and only when the fourth-level mechanical golem blueprint is reached belongs to the precious level. Like the second-level and third-level mechanical puppet blueprints, which belong to the middle and high grades of the precious level, Leo's exchange method is not equal at all, if anyone exchanges him, it will undoubtedly take a big advantage.

This is not the same level as knowledge, and the drawings of experimental equipment are more valuable than some knowledge. Cedric yelled inwardly, and he almost fell down, "My lord, these things are not for apprentices to have. ”

Of course there are no apprentices, but that doesn't mean there are no apprentices behind them. Leo made such an exchange method, without considering those apprentices with no identity background, he set his eyes on those rich and powerful apprentices, "It's okay, I'm not in a hurry anyway, you just ask for it, put it here and sell it on consignment, it doesn't matter if you exchange it or not." ”

Cedric looked at the gadgets in his hand, this thing was really helpful to the apprenticeship, he thought about it again and again before he took out a formula from his waist and said, "My lord, this 'liquid boiling' is an ordinary level potion formula, can you see if you can exchange it?"

Leo took a look, there was only the name and function on it, it was the formula of the potion that he didn't have at the moment, nodded and said, "Yes, I just don't have this potion of yours, it's cheap for you kid." ”

"Is this still cheap?" Cedric wanted to point at Leo's nose and yell, this was obviously a big loss, okay, he didn't plan to continue talking about it, and changed the topic: "My lord, the thing you put here for consignment last time has been booked, I believe that a living blue-veined Rog will be sent soon, please wait for a while." ”

Blue Rogge is not like ordinary Rogge, Leo also knows the difficulties here, it is good to have someone to order, "It's okay, I'm not in a hurry for a while, you can notify me if there is news." ”

"Rest assured, I will be sure to inform you as soon as possible. Cedric nodded affirmatively.

In the meantime, Leo once again took out a handful of gadgets and handed them to the other party: "Put this gadget here for you, let those who want to exchange it try, if you have an idea, you can leave the chips that the other party exchanged, I'll come and see it next time." ”

"Sir, this little thing is so ugly that you didn't give it a name?" said Sidrik helplessly.

After thinking about it, Leo said quite seriously: "Desert Eagle!"

Desert Eagle? Does this look like an eagle? Sidric, though puzzled, didn't ask, but sent Leo away.

On the first floor of the Black Tower, there are not only places to buy and sell items, but also this library, ordinary laboratories, and witchcraft testing rooms, and Leo walks up to the square crystal that he goes to every time he comes, and there is some information on it that is worth paying attention to.

"Mass purchase of common material 'salamander eggs'. ”

"Selling the abrasive 'Raccoon Dog's Mask', a mask that integrates detection and protection, those who are interested in it please come to shop No. 156 for an interview. ”

"Seek two first-level ice attribute mages to explore the 'Ancient Cave Kiln' together. ”

"Exploring the 'Ancient Cave Kiln' is still missing a defense-oriented mage. ”

"I am a strong melee mage, if you want to go to the 'Ancient Cave Kiln', please go to the Black Tobacco Tavern and find the boss. ”

As he looked down, Leo's doubts gradually thickened, and eight of the ten messages were all seeking career matching, and these messages undoubtedly did not point to the place of the 'Ancient Cave Kiln'.

The ancient cave kiln is a general name, and he also knows a general idea of the history of the central part of the country after coming here for two years, not to say that there is no such place, but that was also a long time ago.

"Will the Ancient Cave Kiln be the same as the underground castle on the coast?" Leo had a question in his mind, he had experienced an underground castle once, whether it was a great wizard or an alchemist, it was not as simple as inheritance.

This kind of place does not have absolute strength, it is best not to touch it, Leo finally thought about it, or gave up the exploration of this so-called 'ancient cave kiln'.
