Lin En has never entered a Muggle university in this life, but how come he was taught these things in the nine-year compulsory education in his previous life?!

"Now that you understand the circuit diagram, it's easy. You only need to understand the energy source of the alchemy array as a power source, the rune hub of the alchemy array as a switch, and then understand the various alchemy runes as electrons

components, then the alchemy circle will not be any difficult for you." Professor Green said with great joy.

It is often very difficult for array alchemists to teach their disciples, because unlike legal alchemy, which is more about practice than theory, array alchemy is hellishly difficult in terms of theoretical knowledge. Many talented alchemy apprentices are

After being exposed to the alchemy of the array system, they all complained endlessly.

Especially the alchemical knowledge related to alchemy arrays. There are thousands of forms of alchemy arrays alone. These ordinary array alchemists can only memorize them by rote.

But Professor Green and Lynn are different. After they can successfully understand the alchemy circle as a circuit diagram in Muggle theory, the alchemy circle in their eyes no longer has thousands of forms, but only series and parallel connections.

This is a basic form, because other forms of alchemical formations can be arranged and combined in different series and parallel ways.

After telling Lin En the basic principles of the alchemical array, Professor Green then explained the method of engraving the alchemical array.

The engraving of the alchemy circle is not accomplished simply by carving patterns on the object, but requires the use of a special alchemical engraving knife to thoroughly and permanently engrave the alchemist's magic power on the object.

Forming a closed alchemical circuit allows magic power to flow through the alchemical array. Only in this way can the engraving of the alchemical array be completed.

Professor Green took out a golden carving knife from his pocket while explaining the method.

"Every alchemist will have a carving knife of his own, but for now, you can use my carving knife to carve." Professor Green handed the carving knife to Lin En and said.

Lin En carefully took the carving knife. It was a pure gold carving knife. The carving knife seemed to be engraved with hundreds of dense alchemical circuits. These alchemical circuits formed dozens of different alchemical formations.

Each alchemical circle on this golden carving knife is only the size of a fingernail, which shows how difficult it is to make this golden carving knife.

Professor Green used his wand to outline two strange runes in the air. He said: "These two runes represent the energy source and the rune hub respectively, which are the power supply and switch in the circuit diagram. According to what I said before

Method, combined with the alchemy runes you have learned, I want you to complete an alchemy in front of me. You can enchant any object, oh, except your wand."

Linn nodded.

He hesitated for a moment, and finally took out a big dung bomb from his trouser pocket.

This was given to Zuko by the Weasley twins after they purchased it at Zuko's Joke Shop.

"Big dung bomb?! I just hope you don't make my office a mess!" Professor Green was a little surprised at first, and then said helplessly.

Linn quickly promised that he would not let the dung bomb explode.

Linn sat down at Professor Green's desk and carefully looked at the dung bomb in his hand.

The shell of this dung bomb is not too thick, so Linn must be careful when carving the alchemy circle, otherwise once the shell of the dung bomb is pierced - Linn can imagine Professor Green hanging himself up

The screen is hit.

This dung bomb itself is an alchemical product, but except for the trigger switch, the other alchemical arrays are hidden under the shell. This allows Linn to not worry about the alchemy array when carving a new alchemy array.

Destroy the original alchemy circle of the dung bomb.

Linn carefully used a golden carving knife to carve an energy source symbol on the shell of the dung bomb. When he was carving the runes, he could feel that the golden carving knife was absorbing his own magic power.

When the golden carving knife cuts through the shell of the dung bomb, the magic power is released from the tip of the golden carving knife, and finally is deeply engraved into the shell of the dung bomb, forming magical runes.

After carving the energy source symbol, Linn carved a rune hub on the original trigger switch of the dung bomb, so that the rune hub and the trigger switch coincided. In this way, Linn could trigger the dung bomb and simultaneously make these

The alchemy circle takes effect.

After completing these two strokes, Linn stopped and put his chin on his palm to think.

After a while, he engraved alchemical runes representing "strengthening" and "diffusion" on the shell of the dung bomb. These two alchemical runes can strengthen the power of the dung bomb and reduce the stench after the dung bomb explodes.

The area covered is doubled!

After completing the engraving of the two alchemical runes, Lin En quickly waved the golden carving knife to connect the two alchemical runes with the energy source and the rune hub to form a closed circuit and become an effective alchemy

Magic circle.

Just like that, Linn's first alchemical work - improved dung bomb, is done!

"Teacher, I'm done!"

Linn put down the carving knife, raised the dung bomb and said.

Professor Green came over. He bent down and carefully observed the alchemy circle carved by Lin En. Then he spread his hands and said, "In my opinion, the alchemy circle you carved has reached an excellent level. Normally,

Next time, I will ask you to activate the alchemy circle and experiment with the effects of alchemical products to gain true knowledge through practice. But for now - forget it!"

He doesn't want the stench of dung bombs to fill his office!

"That's it for today. You can go back first! From now on, you will come here every Saturday to practice the engraving of the alchemy circle. Of course, don't bring any more dung bombs with you!"

Professor Green said to Lynn.

Lin En sneered twice, he didn't want to, but the only things on his body suitable for carving alchemy circles are these big dung bombs!

Although clothes can also be used to engrave defensive alchemy formations, he has not yet started learning defensive alchemy runes, so he can't engrave "explosion" runes on his own clothes?!

That's really like going to the toilet with a lantern - you're looking for death!

After leaving the Defense Against the Dark Arts professor's office, Lynn went to find Fred and George and gave them the improved dung bombs he made.

Looking at the two people's ecstatic expressions, Lin En suddenly doubted whether what he did was right or wrong.

He couldn't help but mourn in his heart for the victims of this improved dung bomb.

In fact, Lin En's worry is not without reason.
