"What kind of thing?"

"That's it...... It's ......"

The little goblin felt completely speechless again, and his face was red and red for a long time without saying a reason.

"Forget it, I won't talk about you, as long as you promise to let me out of this library, I'm going back to rest and have classes tomorrow. ”

The leprechaun nodded silently.

The little goblin who was so naughty and mischievous before suddenly became so well-behaved, Al was quite surprised, but he didn't ask anything more, after all, his current state is also quite wolf, Al silently picked up the clothes and shoes that had been separated by the goblin spell and put them on.

These clothes and shoes were all worn by Al from Logging Village, prepared for him by his mother Mayfair herself, and the only equipment Al had on him that was not from Logging Village was the shorts at the bottom.

There's a reason why Mayfair didn't prepare shorts for Al, or when he was in Lumber Village, Al Shorts were often lost inexplicably, and when the washed panties hung outside, they were often gone overnight.

Al had also explained to Mayfair, and Mayfair didn't say anything about it, just showed a mysterious smile that puzzled Al so that he didn't have to care about it.

For Al, his own shorts are simply the easiest thing in the world to disappear, so when he came out of the logging village, Al bought a pair at random in the store, and Mayfair didn't prepare anything for him.

It's just that Al can't understand that it seems that after coming to the outside world, his shorts have never disappeared.

But this is a good thing after all, and Al is not exhausted in such trivial matters.

Maybe it was Al's lesson that really worked, and this time the goblin honestly took El out.

Seeing that the exit was not far ahead, the little goblin in front suddenly stopped.

Along the way, Al and the goblin did not encounter a single patrolling mechanical golem and reader, thinking about the elf's magical ability to change space, Al probably also knew that this little goblin was probably even more difficult than he had imagined.

"It's not far ahead of the exit, and the baby is leaving. ”

"Oh, thanks. ”

“……”

"Don't you even ask for the baby's name?"

The leprechaun puffed out his cheeks and pursed his mouth, and his pink lips curled up like a small bean.

"Well, what's your name. ”

"This ...... I forgot about it too......"

Al: "......"

"You can call me Miss Leprechaun. ”

"Finally don't talk about the baby?"

Al raised an eyebrow.

"You're going to call Miss Fairy!"

"All right, leprechaun. ”

The leprechaun clenched his little fists and snorted through his nose, but felt helpless against Al.

"And what's your name?"

"Me? Al. ”

"Al?" The little goblin lowered her head slightly and silently pronounced the name, and the corners of her mouth quietly hung a smile that she didn't even notice: "It's really an ordinary name, but it's easy to remember, then Al, the baby is gone, welcome to the first library of Valari next time, as long as you call Miss Goblin softly anywhere in this library, I will appear immediately." ”

After saying this, the little goblin pretended to be serious again, and she waved her hand and disappeared in a blink of an eye.

Monday.

A new week.

Alchemy class.

This was not the first alchemy class, but before the class was preceded by an atmosphere of joy and anticipation that had never been seen before.

Because this is the first practical alchemy lesson.

The classroom was no longer the dimly lit circular classroom, but a spacious and bright room with all kinds of transparent glassware, crucibles, measuring tools, etc., and in the last row of the room, there was a row of large gridded display cases, on which were placed many glass jars of various sizes, containing powders and crystals of different colors, some containing strangely colored liquids, and some even processed animal and plant carcasses, rhizomes and leaves.

Seeing such an urgency, Long Chen had a strange feeling in his heart.

Because the environment in front of him made it easy for him to think of the chemical room on the earth, of course, compared to the real chemical room on the earth, the equipment in the alchemy room in front of him is much simpler, and many of the equipment seems to be at the level of the real room, which is nothing more than some weighing utensils, used to hold liquids, Vessels for evaporating or separating solutions, weighing and graduated measuring tools for measuring the volume of solutions, equipment for burning and heating that does not know what solution is in place but should look similar to an alcohol lamp, and crucibles, funnels, glass rods or clamp test tubes are not to mention.

Such a scene was actually expected by Long Chen.

If he came to the alchemy room and saw it full of equipment similar to the spectrum analyzer, thermal analyzer, electron microscope, high-temperature furnace, liquid chromatograph, etc., then it would really be called a living hell.

What really made Long Chen feel weird and concerned was the things on the shelves in the back row of the alchemy room.

The powders, crystals, and liquids in those glass jars didn't make Long Chen feel strange, but the torsos and parts of those plants and animals were what Long Chen found particularly glaring.

After all, Long Chen was a teenager with a formal scientific education.

The precursor of chemistry on Earth was actually alchemy and alchemy, and alchemists before the advent of science used a very idealized set of theories to explain the world.

Western European philosophers initially believed that the world was made up of four substances, including earth, water, air, and fire, and that all matter was composed of these four substances in different proportions, and it was on this theory that alchemy was born, which drove many people to try to smelt worthless earth into expensive gold, and of course, they all failed in the end. (Modern chemistry was finally successful in alchemy, but the cost was much greater than the value of the gold itself.)

At that time, the sages of the East believed that the five substances of gold, wood, water, fire, and earth were the most basic components of the world, and there was still a relationship between them.

But whether it was alchemy or alchemy, the idealized theories became more and more suspicious as people's understanding of the natural world deepened, and eventually they were completely replaced by the chemistry that gradually developed.

Or it can be said that alchemy is actually a precursor to chemistry.
