"Bad guy~Let's discuss something~" The girl timidly stuck her head on the table.

Lin Ze's eyes were still on the parchment roll on the table, and his right hand was gently stretched out, pinching the girl's little face with precision, and rotating it 90 degrees.

"Ah~ Bad guy, I was wrong, don't discuss, don't discuss anything~"

"Find your sister to change the room!" Lin Ze waved his hand without looking back, "I have important things now." ”

"If you want to find a dull use, I went early, and I was pinched back three times~" The girl muttered and left Lin Ze's room pitifully.

To tell the truth, since Leia knew this routine of growing a treehouse, she immediately took over this particularly interesting job, helping the snake girls to build the treehouse in their minds, designing a lot of small houses with different styles, it was really fun, of course, not all the Eteko collected by Luna and Lexi were suitable for this growth method to make the treehouse, the difference in material toughness, branch strength, etc. determines the utilization efficiency of life energy, and occasionally only one or two are barely suitable, and they have to be a last resort. Leia can only use these recovered Etes to transfer life energy, and use the method of spawning to give birth to the nodule branch Nanmu, which is a special tree species that the Ites have improved to use as a growth treehouse.

There are only a few words written on the parchment scroll, Lin Ze is now having a headache about the new currency, the terraces under the fog peak have been done by the enthusiastic snake girl and the minotaur in the past few days, and there are several people who have more than 100 people, but there is no place to use the labor share, and what is the use of looking at the numbers recorded on a piece of parchment every day, and there is nothing to buy, and it will be tired after a long time, and even cause worse things, while everyone's enthusiasm is still there, the new currency must be done.

Lin Ze sorted out his thoughts, among the several types of currency, Lin Ze still chose to use weighing currency, that is, similar to gold and silver coins, and because the new currency is positioned to be of high value, it is convenient to calculate the settlement of high-end products, so he can only take the set of gold and silver books organized by the secret code, and use alchemy metal as the coinage material, which can not only use technology to achieve the purpose of anti-counterfeiting, but also make the currency itself have high value and will not depreciate at will.

The question is, what shape will the new currency take? Round coins? It feels too low-level, it doesn't show its uniqueness at all, the whole Yunshan world is using this kind of round coins everywhere, such as gold books and silver books are more powerful, at a glance it is a high-end currency, like a three-dimensional book, but this is the shape that people have used, headaches, if you want to make money, you must also carry it, it is not easy to damage, the shape of the natural round coin is the best, but too popular.

If only I were an angel, it would be good to make it directly into a feather currency, a feather coin, what a good name, and it has characteristics in appearance, if it is a snake girl, it is not bad, just use it as a tail to mint coins, scale coins, it is also a good name ~ headache, although there are many snake women, the problem is that Lin Ze issued a new currency is obviously not only a snake girl, but also the shape of the scales is not much different from the circle, and the minotaur is not good, otherwise the currency in the shape of a small bull's horn is called a golden horn and a silver horn, and it is a high-grade sound to listen to, is it made into a tree? Golden and Silver Trees? No, the shape of the tree is not good, and the leaves are even worse, and there are so many types of leaves, which are not widely representative.

It must have a unique and domineering shape, Lin Ze set a requirement, domineering, what is domineering? Lin Ze thought about it from a different angle, wait! Knife! Knife Coins! Lin Ze instantly thought of the ancient currencies in his hometown museum, yes, it is the knife coin, the knife ~ the overlord of the soldiers, the knife coin, the six sides form a circle, it looks like a circle and a regular hexagon, and it also faintly implies that the teachers enchant the six-pointed star circle, which means that it is mysterious and domineering, it is perfect!

Just do it when you think of it, Lin Ze hurriedly picked up the pen and drew it on the parchment roll, what does the knife coin look like, the arc back is concave, the tip is slightly concave, there is a ring at the end of the handle, the knife body has an outer edge, the face and back of the knife body can have words or ornaments, and even Lin Ze also thought that different patterns can be carved on the back of the knife body to distinguish the year of minting, commemorative coins? Treasures? Decorations? Hey~Perfect~

The shape of the overall knife coin is set, and the next thing is the value and shape of the currency, Lin Ze has long thought about it, and he must not use the hundred-base system of the pit father, Lin Ze has been miserable by the monetary system of this strange world, gold, silver and copper coins, secret classics and gold and silver books, are all in the decimal system, has the creatures of this world never had such a miserable encounter with only 99 in the whole body several times? It's like buying a black loaf of gold for a copper coin, and then the nightmare comes~ so you have to use the decimal system!

The material of the currency Lin Ze planned to use two kinds of alchemy metals, a second-order silver-white alloy, a third-order gold alloy, and then design a second-order silver knife coin that is a few sizes smaller, so that there are three currency values, which are enough for the time being, as for the size, the small silver knife is the smallest knife coin, so simply use it as change, the volume of the change should not be too large, Lin Ze raised his hand and looked at it, just make it the size of half a little finger, well, other silver knives are the same size as gold knives, the material is different, and the middle finger is so long, happily decided~

After the planning was completed, Lin Ze looked at all the records on the parchment roll with satisfaction, and put it away with satisfaction, it was time to do it!

"In addition to letting you carry out the most basic beam forging training, I have never told you about the synthesis of materials in forging, because it is meaningless, not only because the knowledge of materials science is vast and ordinary life is limited, but also because the manufacture of most high-end materials must involve the participation of soul power, otherwise it is just delusional, so it is useless to tell you, now you have entered the extraordinary level, the spiritual power is highly condensed, and the basic soul power has been formed, it is time to contact the high-end forging knowledge", Iril explained simply, "This is the opportunity you want to craft a new metal currency to familiarize you with the basic use of soul power in forging. ”

"What about the beam forging method I learned earlier?" It took Lin Ze a long time to make the beam forging method reach the gradual realm.

"The beam forging method is the foundation, it is naturally extremely useful, and the soul power and the beam forging method do not conflict", Irel paused, "Okay, let's start with it, first of all, let's start with this silver second-order metal in your currency plan, soul power and spiritual power are both the same source and different, soul power is condensed from spiritual power, and the biggest difference with spiritual power is that spiritual power can only bind intangible things, such as energy, this is the principle of mage professional spellcasting, and soul power is one step further, due to the high degree of condensation, It is possible to bind not only the invisible, but also the tangible! ”
