The scene in the pet building is quite eerie.

The four of them, Shu Meizi and Fat Tiger, sat there flipping through books with an obsessive face.

And the second one held a strange electric soldering iron and buried his head in soldering the "circuit" next to it.

From time to time, he poked with an electric soldering iron, and a small piece of purple-red metal was placed next to it.

Although I feel that the arrangement of the secret magic array in the occult has nothing to do with the welding circuit, it is a pity that the second one can't do it out of thin air, so I can only try to use this tricky way to complete it.

The fuchsia mass of metal was copper, but it wasn't ordinary copper.

Instead, through alchemy technology, the elemental essence is extracted from ordinary red copper, which is the so-called "copper essence", and then the "alchemy copper" can be obtained by injecting the arcane energy into the copper essence for smelting "demon plating".

The materials consumed in the whole process are nothing.

Buying red copper online is about sixty or seventy yuan a kilogram, and Er Yi spent thousands of yuan to buy 100 kilograms at one time.

But in the end, after refining and extraction, he only obtained less than 100 grams of alchemy copper, which is mainly the reason why he is not proficient in alchemy and causes a lot of waste.

The texture of alchemy copper is very soft, and even finger marks can be pinched on it with your hands, but it is an alchemy material with a very high conductivity.

However, if you want to automatically activate multiple spells at once, the rune array that needs to be engraved is too complicated, as long as you get a rune line and a conduction node wrong, it is easy to cause the entire rune circle to fail.

Therefore, even when the second one activated the abilities such as [Specialization-Flexibility], [Skill-Hand Kung Fu], and [Spell-Instant Skillful Hand], he still made several mistakes and lost a lot of alchemy copper, so he reluctantly arranged a multi-faceted magic array.

Carefully inlaid a soul crystal into it, and Er Yi tried to activate this mobile hard disk that integrated [Disciple], [Listening Knowledge], [Teaching Technique], and other spells.

Sensing the arcane energy fluctuations and spell aura generated when the spell takes effect.

Er Yi breathed a sigh of relief, although the low-profile version of the rune array he carved was very rough, but fortunately, the energy supply used was very high.

Originally, the rune circle was supplied to operate, and it only needed to be infused with arcane energy or inlaid with an elemental gem.

But unfortunately, the second one has neither the so-called elemental gems nor the technology to maintain the supply of arcane energy for a long time.

Although the [Empowerment Technique] can inject arcane energy into the rune circle, it is also necessary to store the arcane energy unit, otherwise it will dissipate quickly...... He can't just keep charging this thing, right?

So although it was a bit of a waste, Eryi had to use a soul crystal as an energy source to supply the rune array, but fortunately, it did take effect.

As soon as a "specific person", i.e., a person bearing the [Disciple] brand, touches the drive, the runic circle will activate when it is activated.

With the help of the [Disciple] brand, give the spell effects of [Animal Taming], [Pacifying Animal], and [Enchanting Animal] to people within range.

And through [Teaching Skills], they are taught the ability of [Craft-Raising Animals], [Skills-Domesticating Animals], and [Professional-Animal Tamers].

Although in this way, the effects of various skills are weakened by less than one-tenth.

But for the soon-to-be-established Imperial Spirit Sect, having this "teaching artifact" is enough to train a large number of beast tamers.

The only thing that surprised Er Yi was that the spell of [Disciple] was presented in the form of a rune array, and the effect actually had some changes.

The effect of the [Disciple] released by Eryi himself is to allow the person who has been granted the brand to gain half of the skill level of him, the caster.

The effect of the [Disciple] circle is to give 1/10 of the skill level to the personnel of multiple units, but it can be gradually upgraded through its own learning, and it also has the effect of sealing and erasing memories.

This led to the [Disciple] Circle, which could produce a weakened version of the Disciple in batches, and after thinking about it, the Second One called this state [Apprentice] in order to distinguish it from the members who had the [Disciple] brand.

After finishing the work in hand, Er Yi, who raised his head, found that Shu Meizi and Fat Tiger didn't know when they fell asleep on the table!

Seeing Nobita lying on his side with his head on a pile of study materials, the saliva that flowed out soaked all the study materials, and he couldn't help but sweat a little, and saw that seven or eight hours had passed!

He was supposed to let them go back to their rooms after an hour and a half of learning the effects of the spell, but he was too busy doing his work to forget...... Hopefully they won't be left behind by this.

Seeing that the time was almost up, Er Yi simply called them all up.

Sister Shu is fine, but because she was lying on her arm, her little face was pressed with a red mark.

And the fat tiger was more miserable, the fat tiger tilted his head and couldn't move, and the little man covered his numb arm and began to scream.

Nobita's condition was better, but when he woke up, he found that a study material printed out of A4 paper was stuck to his face with saliva, which was disgusting.

The four people who woke up began to check their learning for the first time, and then they were stunned by the learning content they memorized!

They only watched it once, and they memorized the thick pile of learning materials completely, and they felt as if they understood everything.

"Mom won't have to worry about my studies anymore!"

Nobita, who was moved to tears, ignored the disgusting saliva marks on his face, grabbed Eryi's hand, and shook it desperately as if he had found the underground party of the organization: "Two! Give me another shot of this learning BUFF! I still have to learn!"

"Alright, alright!"

"It's too late, it's too fast!"

"One time is enough for you to digest for a long time, and learning also requires a combination of work and rest!"

"And your current state is just a temporary memory left by hypnosis, don't think that you don't have to learn by yourself by this trick. ”

Eryi quickly shook off Nobita's hand in disgust, for fear that he would rub his saliva on himself: "If you don't deepen your understanding in the future, you will still forget it!"

Even so, the four of them were still excited, especially Sister Shu!

Because there are too many things to memorize in their medical department, it was because she was distracted and busy with the small team that she delayed a lot of learning progress.
