Three days have passed since Emiya invented the Super Battery.

During this time, there were three explosions, each of which was not very large, but left one bleak scene after another in the laboratory.

On one occasion, even the door of the vacuum laboratory was blown out of a groove, but fortunately, the Wei Palace protected him and Cui Xiaoxiao with the Golden Law Star Shield at that time, so there was no human tragedy.

Zhao Mofeng and Wang Yue's vacuum chamber was affected a little, and a hole was opened, and Wei Gong had to spend time to find materials to repair it.

Because of the explosion, Weigong was also complained by neighbors about disturbing the people.

But when he saw the results, he suddenly felt that it was all worth it.

After purification, Wei Gong obtained the high-purity black substance contained in the [Moon Gold].

Judging from all indications, this should be a very chemically active metal element, and it is completely different from lithium, so Emiya is ready to name it after [Wei Jin].

Cui Xiaoxiao still hasn't been able to understand how Wei Gong purified this element from so many impurities to get a very high purity [Wei Jin].

And all of this is thanks to the blessing of the system, since the last time the radar sword was created, the swordsmith level of the guard palace has been raised to level 40, and one of the special skills provided in it is called [Elemental Separation].

This function is very powerful for him, and it can save a lot of refining processes and time.

If he wants to purify a metal according to the normal process, he needs to use a strong displacement reaction, that is, to replace it with a more reactive element.

For example, if you want to obtain silver, you can first replace it with copper, or you can get it through a silver mirror reaction: acetaldehyde reacts with a silver ammonia solution to produce silver.

Later, the more active hydrogen was used to replace silver, and the production of high-purity and high-efficiency silver was started.

If the new metal discovered by Emiya is more active than lithium particles, it is difficult to obtain it by displacement reaction.

Now he is able to master the dosage, and it only takes a few grams of [Wei Jin] to produce a very long-lasting and powerful power.

After repeated tests, the system in Weigong's brain detected that the power of the metal wire made of iron was about 200A.

It's just that because the wire has a certain resistance, the heat generated is too large, and it can be burned immediately after it is turned on.

The rate at which the current is generated depends on the number of charges produced per second, which indicates that the number of electrons produced per unit time produced by the reaction of Guardian with sulfuric acid is very large.

"By the way, how did you know that the power in the wire just now was 200A? You don't even have an ampere meter or a voltmeter, it's impossible to do the calculations! Cui Xiaoxiao clasped her hands and looked at him coldly, there are too many incredible things in this world, and the strength of the swordsmith has exceeded her imagination, there was a time when Cui Xiaoxiao dreamed at night that after dissecting the Wei Palace, he found that he was actually a super robot.

"Ah, that, you won't understand it either." Wei Gong thought for a while, and made a random gesture in his hand, "Actually, for those of us who cultivate immortals, when we reach a certain realm, we can feel the energy in the world, so I can feel the amount of electricity generated in it just now." ”

Wei Gong stretched out his hand to Cui Xiaoxiao's head, she instinctively wanted to dodge, but who knew that the other party's methods were extremely exquisite, and before Wei Gong's movements could be seen clearly, his big hand was already on his head.

Cui Xiaoxiao rolled her eyes, looking helpless.

Wei Gong touched Cui Xiaoxiao's head and squeezed out a smile, "You are still young now, and you will understand when you practice to my level in the future." ”

Half of what he said just now was true and half false, cultivating immortals to his level, he could clearly feel the energy fluctuations, after all, one of the attributes of the wood system was thunder, so just now Wei Gong did feel the current from the wire, but it was not so accurate.

Cui Xiaoxiao blocked his hand impatiently, "Don't fool me casually, and ......"

She pouted, her eyebrows furrowed, and she said dissatisfiedly, "I don't want to cultivate immortals, you remember, I want to explore science." ”

……

In order to prevent the wires from being burned again, Emiya tried several different wire materials, but in the end none of them were satisfactory, so he had to use a transformer to deliver electricity.

The connecting wire part of the transformer to the galvanic battery is made of a material called [crystal worm crystal], which is not satisfactory.

One is because the resistance of this material is relatively small, and the other is because of its high melting point.

However, judging from the heat situation, Emiya felt that he could make an electric oven before he could make the machine tool he needed.

Maybe it's something that Cui Xiaoxiao can't ask for.

She's been trying to eat baked rice cakes lately.

It's a pity that Wei Gong is busy developing power supply equipment and doesn't have time to pay attention to her.

In order to reduce the rate of the reaction, he specially used some inert materials to disperse the [Wei Jin] inside, and then controlled the overflow and the speed of the reaction.

The problem of high-energy batteries was solved, and all that remained was to build the machine tool he needed to produce the wing piano sword.

Then, he had to spend time looking for other conductor materials, first, to solve the problem of frequent fusing wires, and perhaps to prepare for high-voltage transportation in the future.

After doing all this, Wei Gong finally got a wish, and the whole person was as tired as a dog, and just after dinner, he crawled back to his room, and then fell asleep deeply.

At night, Emiya, who was asleep, received an invitation from Kenrin Sakura.

The message in the Qiankun mirror says this:

“

Dear Swordsmith Emiya,

I cordially invite you and your sister Cui Xiaoxiao to come to the palace tomorrow (January 10) to attend the enthronement ceremony of my new emperor.

It is very important that you dress formally.

Sword Rin Sakura salutes

”

Later, another message was sent:

“

Wei Gong, let me tell you the truth, I originally wanted to advocate thrift, and I had already performed the heavenly rites in Yunmenggang before, but Huo Jing and Zhou Sumeng, the ministers, had to fund it to help me hold it once, so I had no choice.

You should be here to have fun, eat and drink by the way, and besides, I have a little gift for you, so be sure to come.

Sword Rin Sakura salutes

”

What the heck?

Wei Gong put down the Qiankun mirror in a daze, and then collapsed on the bed.

After about ten seconds, he rolled out of bed with a bang, and his mind was completely sleepy.

"Oh my God, Xiaoxiao, come on!"
