As soon as I entered the fourth floor of the Mage Tower, I suddenly felt a cool breath on my face.

It's already the middle of June, and it's officially entered the scorching summer, although the latitude of Black Horse Island is high, the rainfall is not small, and it is above the sea, but when it is sunny, it is still frighteningly hot. It was about 278 degrees outside, but when I entered the house, I felt that it was only a dozen degrees.

The temperature difference is staggering.

"Lord Viscount, this is the magic equipment we made with gold pearls, and the outer disc is a controlled magic array, which can be manipulated and adjusted from high to low. As a docent, Granny explained the properties of this equipment to Liszt in detail.

It's basically a disc-shaped piece of equipment with a gold pearl in the middle.

Liszt touched the disc and found that the temperature of the disc was about the same as the indoor temperature, not colder: "Is the temperature high or low now?"

"It's basically a high temperature with low energy consumption. ”

"Adjust it to the lowest temperature and see how much it drops. ”

Granny now lives in the Mage's Tower, eats and drinks, and occasionally goes to Port Town to see stage plays and burlesques. I can often ask the great magician Chrissy for advice, and my life is beautiful, so my temper has improved a lot. He worked very hard, and his tone was much gentle.

"Yes, Lord Viscount. ”

He quickly activated the magic runes on the disc and adjusted them, and after a few moments, the temperature in the room plummeted, getting colder and colder.

When the temperature is lowered to about four or five degrees, it is no longer possible to cool down.

Liszt felt goosebumps on his skin, frowned and asked, "Is this the minimum temperature it can be lowered?"

"I'm sorry, Lord Viscount, I've tried many times with Your Excellency the Grand Mage, but we still can't make the golden pearl freeze, and that's the limit of its magic power. Granny regretted that if ice could be made, the value of gold pearls would definitely double.

Chrissy also shook her head: "It's a pity that the golden lip is a water-type water monster, if it is an ice-type water monster, the golden pearl can definitely make ice." "As a great magician, she can make a small amount of ice by herself, but relying on her personal magic to make ice and sell it is not worth the loss.

Although he felt very regretful, Liszt still said encouragingly: "It's already very good, this hot summer, with the golden pearl, I believe life will be much better...... Did you name it?"

"Please name it, Lord Viscount. ”

"Hmm. Liszt thought for a moment and asked, "Since it can regulate the temperature, can it raise the temperature in winter?"

Chrissy thought for a moment and said, "Although we think that it is an ice property, according to its nature, it is actually more like a thermostat. It's a hot summer, so it's cooling, and in winter, it should be able to heat up. ”

When reporting earlier, neither she nor Granny thought of this, and only thought that the golden pearl could be refrigerated.

After Liszt's questioning, I found out this - since it can be cooled in summer, why can't it be heated in winter? After all, its temperature range is from four or five degrees to more than ten degrees - of course, temperature measurement is only Liszt's feeling, and there is no thermometer here.

"In this way, it can be used for a wider range of purposes, cooling and heating. Liszt is very satisfied with this, the effect of simple refrigeration is limited, and refrigeration and heating are good air conditioners, "Since it is a constant regulation of temperature, then, it is called a constant temperature pearl!"

Black pearls can be crafted into Wind Fixing Beads.

Pink pearls can be crafted into water god beads.

Golden pearls can be crafted into temperature-setting pearls.

The three kinds of pearls have super effects, which makes him very pleased, and it is the best news he has heard in this time: "There are sea monster pearl oysters in the quiet lake of Blue Dragon Island, which can produce white pearls, and only the simple effect of calming the mind and calming the qi is far worse than the three pearls produced in my territory!"

In particular, the black pearl itself has a calming effect, and the white pearl is completely exploded.

He cooperated with Levi and Loria, and had sold the black pearls to many nobles and celebrities in the Grand Duchy, and made a lot of gold coins.

It's a pity that the black pearls have been sold out, and if you want to collect them, you have to wait at least a year and a half - as for the large black pearls, I am afraid that they can only be cultivated for decades or hundreds - but the old black clams live in the deep sea, and as long as they appear in Pearl Lake, they can make a lot of money.

The technology of pearl diving and pearl planting has been explored, which can not damage the life of the black clams.

This is an industry that can be developed for a long time.

Put away your thoughts.

He asked Chrissy and Granny, "What is the scope of the Thermostat Divine Bead?"

"By the standards of this gold pearl, it is the size of a thirty-square-meter room. ”

"Well, it's a little smaller. Liszt complained, and then said, "I will provide you with more golden pearls, you can take the time to make them into the Tempering Divine Pearl, and when the time comes, the Mage Tower will install a batch, and I will need to equip the rest in my Thorn Fortress." ”

Granny was the main force in making magic equipment, and he immediately nodded: "Please rest assured, Lord Viscount, the matter of making the Temperature Fixing Divine Bead will be left to me." ”

......

Goldlipped mussels are sea monsters that release a normal magic spell - water bombs.

The most suitable collector is the krenken Ark, but Ark has recently been preoccupied with natural magic, and Liszt did not disturb her, but rode the colorful whale Rose himself and swam to the golden-lipped shell habitat near Rocky Island. Look for a large golden-lipped mussel, get closer, and lure it with food.

Wait for the golden-lipped shell to open its shell, and then stuff a dragon bone like lightning to resist the golden-lipped shell's defenses, and then hold the shield against the water bomb it releases.

Quickly cut the film that encloses the gold pearl and remove the gold pearl.

Stuff in a grain of sand and pull back the dragon bones.

In this way, the gold-lipped mussel will be fine, and it can continue to give birth to golden pearls - the sea monster is very resilient, as long as you don't toss around, you basically can't die.

Shellfish such as golden-lipped mussels and black clams can be treated in this way, but the really difficult thing is the pink conch, and there is no way to take out the pink pearl without killing the pink conch.

And so on and so forth.

In one hour, Liszt obtained fifteen golden pearls.

He calculated, it should be enough to meet the demand, the castle needs to install the temperature of the Divine Bead in no more than ten swords, and the mage tower to install five more, exactly fifteen. As for the existing one in her hand, she can give it to Ake, so that she can play and study it.

The main reason is that the gold-lipped mussel population is not large, and the number of egg-sized qualified gold pearls is even smaller.

Otherwise, Liszt will definitely collect a large number of them, make them into temperature-fixing beads and sell them to the outside world, and earn a lot of gold coins to buy supplies.

It seems that good luck has returned.

The good news of the golden pearl here has just been digested.

On the other hand, another piece of good news came - the weaving workshop had finally spun the green feathers of the green caterpillars into cloth and sent them to the castle for Liszt to admire.
