Only then did Fang Plover see that the different doors were divided into three colors: red, green and blue. He nodded and walked towards the small green door at the bottom. Before he could get closer, he heard a voice from

came from my heart:

"The green door symbolizes knowledge."

"The blue door symbolizes challenge."

"The red door symbolizes danger and opportunity."

That was Anlose's voice, and with this voice, the door opened in front.

Fang Yu was startled, but paused and found that the other party did not seem to notice Miss Tata, and then he felt relieved. He couldn't help but think of the other soul in his body. Since leaving the Ash Mountain Forest, that thing has

There has been no movement for a long time.

The thought flashed across my mind.

The green wooden door in front was slowly opening. There was no view of what was going on inside the house behind the door, only a huge whirlpool that seemed to block everything.

Fang Plover looked at this scene and hesitated for a moment. But the tower guard's voice came again: "Don't be afraid." The latter took a gentle breath, then nodded and stepped in.

As soon as you enter the door, the scenery in front of you changes.

First of all, when the previous magic circle was activated, the buzzing in his ears disappeared, and the room seemed to be isolated from the outside world. It was quiet. There seemed to be light in the room. He opened his eyes and was startled that it was a small

In the study room, there is a desk, scrolls spread out on the table, and bookshelves lined up on both sides. Books of all sizes are scattered on the floor of the narrow room, leading to a floor-to-ceiling window at the end.

The light flows in from the window, soft, like spring sunshine.

In front of the desk, there is a huge open book, displayed on a wooden brass base, half as tall as him. The room is brightly lit, and there are some strange symbols written on the pages of the open book, and a huge one is painted on one side.

Pattern talisman case.

Ordinary people might be a little confused when they see these mysterious symbols and patterns. But in Fang Yu's eyes, these things couldn't be simpler. To be precise, they are the foundation of alchemists.

Rune single characters, and single array.

A single formation is an alchemy formation with only one function.

It is composed of single runes and mobilizes the flow of ether in one direction. It is the most basic unit of alchemy.

The single formation is an ancient product of the era when alchemy was born. Nowadays, almost all alchemical formations are compound formations. The single formation has already existed in the history books in Aitaria. But to this day, it is still

A required course for every alchemist apprentice.

Fang Yu looked at this big book and couldn't help but think of his study experience in Kapka. It was not that long ago, as if it was yesterday.

However, he didn't quite understand the purpose of this book appearing here. Looking around the room, it was crowded and there seemed to be no other exits. Only when he raised his head did he realize that the ceiling of the room was quite high.

And in that place, there was actually a small green door.

The exit is there.

How does he get up there?

Use the twinkling ability of the Energizer? However, Fang Yu tried it and found that he could not summon his own construct in this mysterious space. Even when he took out the clockwork fairy hanging on his belt, he could not produce it with its core crystal.

Any contact.

This space seems to have the ability to isolate the ether.

Fang Yu thought for a while and felt that this trial might not be that simple. If an angel could take him up there, wouldn't it be easier to get in through the flying boots? He then began to look at the surrounding environment carefully, and then he discovered

Some details.

There are some red gold plates scattered on the floor.

And red gold is a good conductor of ether.

At the same time, he is very familiar with this kind of cheap material, because it is something that every alchemist will come into contact with during their apprenticeship, and they must handle it when they practice carving formations for the first time.

Looking at the big book and then at these red gold plates, Fang Yu suddenly understood what he was being asked to do here, which was to let him carve formations.

But what's the difficulty?

After all, he is no longer an apprentice. At that time, if he wanted to carve a single formation, he would even need to use chisels and hammers to tap on the gold plate to carve out the formation seals stroke by stroke. The alchemy formation is a very rigorous thing.

If there is any mistake, the magic circle will be scrapped.

But now, he just needs to pick up the gold plate, and with a flash of thought, he connects every necessary structural point, and the magic circle in his hand is formed naturally. Even a single formation is no challenge to him at all.

As soon as the engraving on the gold plate was formed, it immediately took off its hands and flew out, forming a staircase in the room.

At this moment, the big book also turned a page, but there was still a single formation on it. When Fang Yu saw this scene, he completely understood that this room was the basis for testing the alchemist's apprentice, depicting alchemy.

Magic circle.

He looked at the height of the ceiling. It seemed that there were about seventy or eighty steps to reach it, and this number was almost exactly the total number of single formations invented by alchemists since the days of Numelin.

Now that he understood the principle, Fang Plover stopped wasting time and started laying the steps step by step.

The big book kept turning pages over and over, but on the seventeenth page, Fang Plover experienced failure for the first time. Probably due to a slight distraction, his accuracy in depicting the magic circle this time was about 90%.

.

Of course, this accuracy is high enough, because generally speaking, an accuracy of more than 70% is required to form an array, but even so, when he formed an array, the gold plate in his hand still did not respond at all.

Fang Yu was slightly startled, and subconsciously tried several times, each time increasing the accuracy step by step until it reached 97%, before the red gold plate flew out from his hand, forming the next step. Fang Yu couldn't help but gasped when he saw this scene.

After a breath of air-conditioning, I realized the power of this place.

It actually requires the formation accuracy to be at least ninety-seven in order to pass the test.

After studying the basic knowledge in Du Lun, Fang Pliance is no longer the novice he was before, and has no basic concept of the alchemist's accuracy. Of course, he now knows what 97% accuracy means.

This means that at least two-thirds of the craftsmen's qualifications will be eliminated, because it is almost impossible for them to achieve this level.

This is just the first door.

Fang Yu couldn't help but raise his head, took a deep look at the door on the ceiling, and realized for the first time the extraordinary nature of this Thousand Doors Hall.
