The idea of ​​creating a super lightning cage is Mobius's proud work.

For this idea, he did countless experiments, and now Rosen said that there was a fatal flaw. He suddenly felt a little unhappy, as if his child was said to be ugly.

Mobius glared at his eyes and said angrily: "Fuse...What flaw? Why didn't I find it?"

His appearance seemed to be like he was going to settle the score with Luo Sen if he didn't explain it clearly.

Rosen reached out to grab a battery and shorted the positive and negative poles together.

When short-circuited, the circuit resistance is almost equal to zero, and a huge current naturally appears in the circuit. The short-circuited positive and negative electrode metal sheets immediately start to turn red, white, and then start to smoke, and finally melt into metal juice.

Rosen kept moving. After the metal sheet melted, he activated his magic power, connected the metal juices together, and continued to short-circuit.

In less than 2 minutes, the short-connected metal began to slowly darken and solidify. After 4 minutes, the battery was exhausted and there was no movement or static at all.

Rosen handed the battery back to Mobius: "Touch and see."

Mobius reached out to take the battery. As soon as his hand touched the battery, he immediately let go. The battery fell to the ground with a slight crack. The ceramic shell was smashed and the electrolyte inside spilled on the ground. It was actually hot and steaming.

"What's the matter?"

"It's very hot, very hot!" Mobius said.

Rosen spread his hands: "Look, this is one of the flaws. A thunder cage, when the two poles are directly connected, becomes so hot. If hundreds or thousands are connected together and still do this, I'm afraid that the monster lord will not die, and these thunder cages will destroy themselves first. The liquid in the cage will become hot, start to boil, and the pressure will also increase. Maybe the thunder cage will explode."

"This..." Mobius was a little stunned, but he was unwilling to give up and said, "I admit that direct shorting will cause great harm to the lightning cage and may even destroy it, but there is a solution."

"Let me tell me." Rosen wanted to see Mobius's level.

Mobius took out a graphite from his pocket: "Look, this is graphite. Like materials like iron and copper, it can also lead the power of lightning, but it is not as strong as iron and copper. On the other hand, graphite has a certain restrictive effect on lightning. I can add graphite to the lightning path to limit the power of lightning, so that the lightning cage group will not be burned."

Adding resistors to the circuit to limit the current...Mobius actually thought of this trick. It's good, very good. Rosen began to appreciate Mobius's abilities.

Perhaps the scientific research ability of this undead tribe is very average, but this guy has great enthusiasm for the alchemy field and is almost unlimited. No matter how stupid his head is, if he works day and night, he will be very likely to gain true knowledge.

Rosen nodded in recognition of Mobius's approach: "Well~ Your idea is very good and it is indeed effective. However, there is another flaw that you may not be able to solve."

"you say."

Luo Sen reached out and knocked on the thunder cage on the table and asked, "How long does it take to build such a thing and how much material will it take?"

"Uh~ It takes 4 days. If the materials are in, it is difficult to find, especially the liquid inside, which is very difficult to match."

"One is 4 days, how many days will it take for ten thousand?"

“Uh~~~”

Mobius lost his words at once, and the blow was very big now, because what Rosen said was the truth.

To create a reliable and excellent performance lightning cage, many rare materials are required, such as copper, lead and other metals with extremely high purity, various acids, and good sealing is also required to create one or even one hundred. It is not a big problem, but thousands or even tens of thousands of lightning cages are needed at once, and these lightning cages need to be connected together to use, which ensures that there is no problem with each one. Just thinking about it makes people feel desperate.

"Perhaps, these flaws can be avoided by improving the performance of the lightning cage..." Mobius was still unwilling to give up.

Luo Sen smiled and said, "The method you mentioned is naturally feasible. Then I ask you again, these lightning cages are disposable. Even if you don't use them, the lightning stored in them will slowly disappear. This requires us to maintain this lightning cage group in the later stage. How do we calculate this expenditure?"

"Uh~~~" Mobius licked his dry lips and couldn't answer the words at all.

After a long time, he spread his hands: "What should I do?"

"I have found a better solution." Rosen smiled.

"What method?" Mobius suddenly lit up and looked at Rosen with a longing look on his face. These days, he has studied the lightning cage, which can be said to be a waste of time and sleep, and has a very deep understanding of the power of lightning. But the deeper he understands, the more he feels that the depth of lightning is unfathomable, so he wants to know more.

By now, he has been deeply fascinated by this wonderful power that only gods can use. If he had the opportunity to have a deeper understanding of lightning, he felt that he was willing to give everything for it.

Luo Sen smiled slightly and attacked the wooden frame on the wall behind him. Under the influence of magic, two square black stones and a square copper bar flew towards the two.

This square copper strip is very strange in style. One of the sides is not closed. It leads to two lines, which are very close to each other, only about 1 mm.

Mobius took the black stone and looked at it, becoming more and more puzzled: "Is this... a magnet?"

"Yes, it's the magnet."

Rosen picked up two square magnets, activated the magic power, and used the magic power to hold the two magnets to let the magnets levitate in the air. The two magnets had poles opposite each other, keeping them parallel to each other, and were 15 cm apart.

Mobius became more and more confused as he watched, and he couldn't figure out what Rosen wanted to do.

Luo Sen didn't explain, and his mind moved again, and the square copper bar flew over and floated between the two magnets in the form of parallel square magnets.

"Look at it." Luo Sen smiled.

"I'm watching." Mobius's eyes didn't blink.

Luo Sen's thoughts were aroused, and the strange-style square copper strip rotated between the two magnets, and at first, it was just turning slowly.

"It seems that there is no change." Mobius said.

"Don't worry, it's just starting."

The square copper bars were turning faster and faster, and gradually, the copper bars were completely out of sight, leaving only a high-speed spinning afterimage.

"There is still no movement..."

Before he finished speaking, a silver-white lightning suddenly flashed on the two specially drawn joints on the square copper strips, and a stable lightning flashed between the two copper lines. At the same time, a "crackling" explosion sounded in the air.

This fine lightning bolt is less than 1 mm in length, but it is very bright. Whether it is a loud explosion or a dazzling light, it cannot ignore its existence.

"This...this...how is this? You...have you used magic secretly?" Mobius was dumbfounded. He pointed at the copper ring that was still rotating at high speed, and his arms couldn't help but tremble violently.

Luo Sen smiled and said, "The structure of this thing is so simple, it's just two magnets and a copper bar. If you want to know if I have used magic, would you know if you go back and do one?"

This thing is actually a generator, the principle is electromagnetic induction. On the earth, this law was first discovered by the famous British physicist Michael Faraday.

"Yes! Yes! You're right. I'll go back and make one now, but... the magnet is so fixed and I don't have magic. How can I make the copper ring turn?" Mobius kept touching his bald head, rubbing it with shiny light.

"You know, Thunder and Lightning doesn't like wood. You can make a runner with wood and then put the copper ring on it."

"Yes, yes, I'll just make a wooden wheel... No, I can't stay here, I have to go back and verify it immediately!" He felt that he could not delay for a moment, and hurriedly left Luo Sen's room.

Luo Sen smiled slightly, and he sat down on the chair, took the manuscript paper, and began to draw sketches of the electromagnetic generator on the manuscript paper.

If you want to get huge electricity, the battery solution is unreliable, and using a generator to generate electricity is the right way. The power of this generator must be very large, and it must not be weaker than the power of the lightning messenger Max when he released lightning... No, no, it must be stronger than Max, at least twice as strong as him.

Anyway, the stronger the better!

When drawing the drawings, time passed quickly, and the day passed quickly. When the sun set, Rosen was also croaking hungry. He put down his work and stood up to go to the restaurant.

As a result, before he walked a few steps, the door of the room was pushed open with a slam and Mobius rushed in.

"What's so urgent?" Luo Sen asked knowingly.

Mobius waved a wooden simple generator in his hand, his face flushed red, and his eyes were bright like a light bulb: "Rosen! Rosen! You are such an unparalleled, unprecedented genius! God~ You actually created lightning with such a simple method!"
