Three days later, what Fang Tian was looking for had been found.

But these three days made Fang Tian realize very deeply that it is really not easy to be an "inventor".

Or rather, it's hard.

This kind of directional search, which is like fishing for a needle in a bowl, as well as comparative experiments, and even more magic, should be cost-effective and time-consuming.

But that's not the case.

When the experiment ended due to success, even Fang Tian felt a faint feeling of exhaustion.

It was definitely not because of a lack of mental power or anything, but just a trace of impatience in consciousness for this kind of "frequent", "again and again", "continuous" experiments.

Although this impatience was indeed only a "hint", how keen was Fang Tian's physical and mental feelings now?

This discovery had to make Fang Tian sigh in his heart.

Sigh the difficulty of invention.

It is said that when King Edison invented the filament, thousands of materials were tested before and after.

Fang Tian had heard this story a long time ago in his previous life, and he also praised it from the bottom of his heart. But to be honest, at that time, Fang Tian really didn't have a real concept of these "thousands of kinds".

If a person spends eight hours a day, nay, twelve hours a day, on these "thousands of materials," how many can he experiment with in a day?

Edison didn't take long, a few years at most.

But this gentleman is actually an "unborn" figure, and his example is not a conventional reference.

He spent only a few years. But if it is placed on others, it is placed on other "ordinary inventors". In the past few years, it is likely that it will need to be expanded, expanded to more than ten years, or even decades.

In other words, what an invention represents behind it is likely to be a lifetime.

A person's life, in the face of such facts, is really insignificant.

If you don't just want to live, you want to "do something".

Just living as usual. At that time, it was like a leisurely flowing stream, and if you want to pursue something and struggle, it is easy to find it. The creek, I don't know when. It became a waterfall.

The torrent went straight down to 3,000 feet. It's not water, it's time.

In the past three days, Fang Tian had tested a total of four hundred and ninety-two kinds of materials, and this was because he knew what the characteristics of the materials he was looking for generally possessed.

If it's just a clueless search and experimentation. Like Edison's real yàn filament, I am afraid that this number will be expanded tenfold. - Well, that's basically about the same amount as Edison's filament material.

Actually, theoretically. There is still a way to reduce the number of "four hundred and ninety-two" even a lot.

If Fang Tian is a botanist.

But sadly, he is not.

Alas, if only I had been a botanist in my previous life. In Fang Tian's heart, he sighed slightly again.

But no matter how he sighed, now, Fang Tian was confident that he could make the paper he needed, including the "brocade", including the flowers that could be added to the "brocade".

In the past three days, in the interval of testing the seasoning package, or in order not to be too busy with one thing and lead to Alzheimer's disease, Fang Tian experimented not only with the seasoning package, but also cooperated with many papermaking materials.

In this process, the role played by magic can be called an "artifact".

In the hands of a median mage, magic plays more than just a substitute for real equipment, in fact, it is only a trivial one of those functions, and the real role of magic, which can be called an "artifact", is to greatly reduce the time required to implement it.

How largely?

In the previous life, it took a hundred days for a papermaking workshop to experiment with a material, but when it came to him, it only took five minutes!

Yes, that's right, five minutes!

In fact, it took about twenty minutes to take half a magic hour at first, but as the skills improved, practice makes perfect, and the application of comprehensive spells improved, this time was gradually shortened until it was shortened to five minutes!

It can also be said that in the past three days, in the paper industry, Fang Tian has completed the course of countless papermaking workshops in the past thousand years with the insight of a latecomer and the "divine power bonus" of magic.

Now, in papermaking, he is already an out-and-out expert, a big expert!

Even if you don't say it modestly, it's not an exaggeration to call it a grandmaster.

If he wants, if he doesn't think about anything else, he can write a book "Paper Integration" now, and this book must be a classic.

Of course, in fact, it was impossible for him to do this.

The paper is finished, and the next step is ink.

Compared to paper, the method of making ink is much simpler.

It's so simple! The two are not an order of magnitude at all.

Papermaking Fangtian needs to test four or five hundred kinds of materials, this is just a "seasoning package", plus raw materials, there are seven or eight hundred, but how to make ink, let alone seven or eight hundred, not even seventy or eighty!

In this era, every family has the simplest ink, and each has at least two "processing plants", which are processing ink non-stop all day long.

The first processing point is the oil lamp.

The second processing point is the pot stove.

Lift up the big iron pot that cooks every day in the west courtyard of the Fenglin Compound, turn it over, and touch it with your hand, and a magical change will immediately occur - the white hand will become black and black.

Scrape off the black ash and mix it with water, which is the most authentic ink.

This is the cauldron.

Of course, the same is true for oil lamps, but the ink point on the lamp is the lampshade.

Generally speaking, the ash in the lampshade is darker and more delicate than the ash at the bottom of the cauldron. Of course, the so-called delicate, delicate to the extreme, is the so-called "nanoscale" in the previous life.

The level of ink also shows the difference here:

1. See who's darker.

Second, see who is more delicate.

As a great writer, he is also a calligrapher, one of the four Song families, Su Shi. Su Dongpo, that is, His Excellency Su Changmian, once said about ink:

"In this world, ink is the only light to be taken. Light but not black, is to discard ink. It's black but not light, so it's not spiritual, and it's also used in peace. It is good to make it clear and not floating, and it is good to be as clear as a child's eyes. ”

Although Su Dongpo's calligraphy was ridiculed by Huang Tingjian, who was also one of the four Song families, as a "stone pressed toad", his view of ink is still very accurate.

The ink in this sentence. In fact, it is also the common requirement of countless calligraphers for ink.

Of course, like papermaking, you can add "thirteen incense" to the paper to make the paper present different characteristics, such as green paper and red paper. Murray can also add spices, this aspect. In the previous life, people of Fang Tian's era should be easy to understand.

Like eating ice cream. Strawberry, vanilla, mango, melon, chocolate, whatever.

Add a little perfume to the raw materials of ink, and after the ink is made, it is fragrant ink.

I took a piece of ink and sniffed it with my nose, the so-called "refreshing people's spleen" is not nonsense. Of course. This fragrance is not added casually, and some fragrances and ink are mixed together, and the taste will become extremely evil.

However, this is only a minor issue.

Paper also needs to be tested over and over again. This ink, Fang Tian hadn't tested it yet, and he already had a bottom in his heart.

Next, it's time for the pen.

Brush, hehe, compared with paper, compared with ink, the difficulty and process of making brushes have been attenuated a lot.

If it is said that the writer in the previous life or an ordinary person made a pen would still be very concerned about the subtle adjustments involving those hairs, for a mage, this is really not worth mentioning.

The so-called four treasures of the study, pen, ink, paper, inkstone.

In this way, the paper has passed, the ink has passed, the pen has passed, and then the next thing is the inkstone.

This one is even simpler, so simple that it can be completely summarized in just one sentence: "The stone with a concave stone is an inkstone." ”

Pick up a small stone on the ground, of course, the small wooden block is also formed, which can be placed on the table smoothly, and there is a recess on the stone and wooden block, which can hold ink, which is the inkstone.

Of course, this is the most basic and crude inkstone.

On this basis, there can also be various particulars, such as not using stones and wood, but using jade, what Lantian jade, white jade, mutton fat jade, can be.

In Fang Tian's previous life, the elder who named a pair of children Tang Kai and Tang Xiaozhen had a set of inkstones called "five-color stones", which were carved from black, white, blue, red and yellow five-color jade.

Once, during the guest room, Fang Tian once asked with a smile, why don't you upgrade the five-color stone into a colorful suit?

The elder laughed, mending the rhyme of the sky!

Then he explained that the rainbow was a little "colorful" in the end, and it was not suitable for the study room. If Xiao Zhen likes calligraphy, I can give her a set of these, but unfortunately, she doesn't like it.

Between the words, there is a lot of regret.

The four treasures of the study, the "treasure" has been prepared, and the next one is the "room".

Fang Tian was now a mid-rank mage, and he was also the master of a city, and his situation was very different from when he was a magic apprentice, and there were many things that could be ignored. With his current level, he can completely open his golden finger and create a rather "idealized" study for Xiao Loli.

Of course, his own is exempt.

As his cultivation progressed, more and more curtains swept over the ground, and Fang Tian couldn't remember how long it had been since he had been to his hut.

built a house for Xiao Loli, and the location of the house was chosen by Fang Tian near the center of the association, which is now called "Seven Star Lake".

In fact, since Little Ivy and Nanhai Thirteen left respectively, Little Loli lived in the Maple Forest Compound, which was a bit inappropriate. The reason for the inappropriateness is naturally very simple, everyone in the compound, even a few magicians such as Moritsch, have companions.

She was alone, alone.

At the beginning, Fang Tian was still in the compound from time to time, so it didn't matter. Now, as he stayed away from the compound for longer and longer, it was time to move her out. (To be continued......)
