"Help me prepare a copy of the raw materials and principles for the production of lighters, if the cost is not too large, the daily necessities factory will specialize in producing this in the future. Pen & Fun & Pavilion www.biquge.info" Yun Feng said without thinking about it.

Because Yun Feng found that there seems to be no more mature fire-making device in this world, and there is no gas pipe here, and second, there is no induction cooker, so it is a troublesome thing to make a fire for cooking.

Cultivators can say that a single fireball technique or fire-based fighting skill can ignite a small flame, and even if there is no fire-attribute talent, they can barely release some relatively basic fire-based skills.

However, some civilians who do not have the talent for cultivation do not have this condition, they can only rely on fire knives and flints to make fires, not only the life process is troublesome, but it takes a lot of time to completely ignite the incendiary objects.

In order to save time, some families will not completely extinguish the stove after each meal, and cover the remaining charcoal with sparks with soot so that it can be lit directly next time.

But this is obviously a waste of fuel, after all, the interval between meals is still a bit long, especially between dinner and breakfast, leaving too much waste, leaving less is not enough, and the slightest carelessness will completely consume the remaining stove.

As long as the lighter can be put on the market, and the price is within the range of the common people, I believe that the sales must be good! Maybe even some high-ranking officials and nobles want to have a luxurious lighter to show off!

"The principle of lighter making is being constructed...... The architecture is complete, and the materials needed to make the lighter are being proportioned...... The ratio is completed, and the lighter after the ratio is completed needs the fire magic crystal nucleus (stone) and dissolved element water、......。 It is estimated that the base cost of a lighter is about eight copper coins. ”

After receiving the lighter production principle sent by the system, Yun Feng didn't see the need for raw materials such as oil, which also made Yun Feng breathe a sigh of relief, if he really needed oil, then Yun Feng really didn't know how to get it, and he couldn't let him build an oil well, right?

Moreover, according to Yun Feng's understanding and systematic analysis, this world will not produce oil, and the oil in this world will remain in the form of magic crystals, and the corpses of animals and plants will decay and crystallize after endless years, and finally form magic crystals with various elemental attributes.

The dissolved element water is a kind of alchemy raw material, which can convert the solid magic crystal into a high concentration of liquid energy liquid, which is usually used in the quenching in the forging field or the preparation of the agent bearing liquid in the field of medicine, which is a relatively common and commonly used material, which is easier to obtain than the condensate water droplets.

The combination of dissolved water and fire magic crystals can produce a highly concentrated fire solution, which can be used as a household fire after dilution, and then add some miscellaneous such as ignition devices and containers.

Although the materials used in a lighter look relatively high-end, in fact, the volume of a lighter is so small, although the materials are somewhat valuable, but when evenly distributed to a lighter, it does not seem so much.

"I know, generate relevant instruments and equipment, you can look at the deduction at the exchange point, just don't be too outrageous. After waving his hand, Yun Feng looked at Steve, who was sorting out his brain memories, and commanded the system.

According to Yun Feng's observations, Steve's brain fluctuations have completely stabilized now, which proves that Steve has now completely sorted out that memory, and is now probably swimming in the sea of knowledge.

Suddenly, a wave of unstable magic fluctuations came out, and under Yun Feng's frowning brow, Steve was promoted without warning!

For Steve's sudden promotion, Yun Feng was also a little surprised, and at the same time a little confused, is it a bit of a waste for such a good seedling to let him give up magic?

A slight stimulation of Steve's brain, a slight tingling sensation came, and Steve suddenly woke up, only to find himself still sitting in a chair in the teacher's office.

Seeing this scene, Steve hurriedly left his chair and stood up, it was extremely impolite to sit down at will without the consent of his elders!

While standing up, Steve also found out that he had been promoted to an intermediate magician! This has to be said to be an unexpected joy, resisting the urge to cheer Steve, who was waiting for the teacher's teaching, suddenly realized a very serious problem!

The teacher once said that he would give up magic by himself! Doesn't that mean that no matter what realm he cultivates, he will have to give up anyway, thinking of this, Steve's original excitement instantly collapsed.

As if seeing Steve's thoughts, Yun Feng coughed lightly and said, "Don't show that expression, I won't object if you want to learn magic, but magic will have a big conflict with what I'm about to give you!

Hearing Yun Feng's words, Steve closed his eyes and thought for a moment, and then said categorically: "I'm willing to give up magic!

"I'm glad you can have this choice, it's not a bad thing to give up magic, I'll tell you the specific reason at the right time, although you give up magic, I will still teach you other cultivation systems, this kind of cultivation system can not only maximize the development of your brain, but also has a huge help for your future scientific experiments. ”

After saying this, Yun Feng stretched out his hand and pointed at Steve, with a soft "poof" sound, Steve only felt that the source of magic that had been condensed in his body for five or six years disappeared, but surprisingly, at this moment, a comfortable sense of relief spread all over his body.

Then a point of light emerged from Yun Feng's hand, slowly drifting towards Steve's brain, and burrowed into Steve's brain without hindrance.

"This is a seed of spiritual power, it will constantly stimulate your spiritual power and activate it," Speaking of this, Yun Feng took out an iron gall, "This is for you, come to me when you can make this float, and I will take out the spiritual power seed I planted just now." ”

"Oh! That's right! I'll give you a research project first, this is a copy of the principle of making a generator, this is my Elder Token, this is five hundred gold coins, the materials in the guild warehouse are at your disposal, I want to see a working alternator within a month!"

As a result, the teacher handed over the information, tokens, and money bags, and Steve felt valued and trusted for the first time! Although there were some high-ranking members who would give some precious items when they issued tasks, they all needed guild points or other things as collateral.

But now the teacher has directly handed over a huge sum of money to himself, as well as his Elder Token! You must know that the Elder Token can take any materials in the guild's warehouse at will! If you take a few precious materials and escape, the guild's loss will be great!

Although Steve's sense of belonging to the guild is not too strong, to put it bluntly, he is a mixed meal, but for Yunfeng Steve, who is his mentor and life-saving benefactor, he began to respect it in his heart.

After saying goodbye, Steve hurriedly left the tower and returned to the dormitory to begin to study the principle of making the generator, which is just to tell you some necessary knowledge, not just to make parts and put them together like an assembly toy manual.

Now Steve had to conceive a generator based on his own understanding, then make the corresponding parts based on the generator he had conceived, and then put those parts together to see if his idea was feasible.
