"What is a generator? Can it be made of lightning? Can it be made of heavenly tribulation?" Xia Qingqing, Beichen Yuqing, Fang Shijing and Ling Zhifeng were surprised, and looked at the thing in front of him in panic - is this the generator?

The generator has completely changed a lot; the volume has increased to about two meters, and the internal lightning and thunder are roaring, and four pairs of spirit gathering array wires are connected to the external spirit gathering array; the generator's own spirit gathering array has been cancelled, simplifying the device.

The two ends of the generator lead out a wire that is as thick as a finger, wrapped in dry burlap, and more than 100 large light bulbs and light bulbs are connected to the other end.

It is good to have practice. As long as Li Xian opens a head, the remaining test items can be made with spells - although the light bulb is a bit ugly, at least it is enough to do experiments.

Now, Tang Rong and others are no longer so afraid of electricity, and are able to explore electricity with the spirit of exploration; they have long since no longer cared about "stealing the power of heaven". If they really steal the power of heaven, the punishment of heaven would have been lost.

Since there is no heavenly punishment, it means that this thing can be studied. Only those who are brave enough to make a breakthrough. Li Xian went to Wuyang City for a walk, and they solved many problems. Even Li Xian mentioned various tools in the past were made.

If you can cultivate the truth, especially those who have reached the foundation-building stage, there seems to be no fool.

Seeing that the formation generator technology was initially mature, both Li Xian and Xu Ren were surprised to go up and watch, throwing Xia Qingqing, Beichen Yuqing, Fang Shijing and Ling Zhifeng aside.

Although Xia Qingqing has suffered a lot since childhood, she is wise. However, seeing that Li Xian is so "irresponsible", she threw herself, a delicate beauty, aside and looked at the cold machine, which was still a bit delicious. But finally she followed Li Xian, wanting to see what magical thing this "generator" is.

On this side, Li Xian personally participated in the inspection and confirmed that there was no problem with the conductor insulation, and then personally merged the switches.

Suddenly, more than a hundred light bulbs that had been prepared beside him were lit at the same time; in an instant, the dazzling light burst out, which surprised Xia Qingqing, Beichen Yuqing, Fang Shijing and Ling Zhifeng. Xia Qingqing was even so scared that she lay behind Li Xian. She looked very cute when she looked at her head.

Unfortunately, Li Xian only has the generator in his eyes. After seeing the light bulbs on and the current voltage of the ammeter stabilized, he was finally overjoyed, "Haha, it's so good, the power problem is solved, and the wire problem is also solved! After solving the wire problem, we can truly let our dreams go! Okay, so good!

Next, we are preparing to build an electromagnetic vortex heating furnace. This kind of heating furnace requires alternating current. Do you have any ideas about this?"

It turns out that the current of this array generator is more like a fuel cell, and it outputs DC power rather than AC power. Although DC power is very good, AC power is undoubtedly better in the early stages of the development of electricity.

Tang Rong smiled confidently, "Young Master, we have already thought about it. The solution is very simple. Just add an yin-yang conversion array to the two wires. In this way, as long as it is set, the current alternating frequency can be easily changed.

Look, we have already made it."

Li Xian looked at it and it was a watermelon-sized rotating device driven by the engine. The entire device was divided into three parts, with the front and rear parts fixed, and only the middle part rotated, which turned out to be a Tai Chi disc. As long as the Tai Chi disc rotated, the positive and negative changes of the current can be easily changed.

"That's great!" Li Xian was really overjoyed. It seemed that the most difficult time had passed. Now the research on wires and electricity has made great progress.

Next, everyone began to discuss how to make a "heating furnace".

Li Xian directly put Xia Qingqing, Beichen Yuqing, Fang Shijing and Ling Zhifeng aside and started a discussion:

"The melting temperature of jade should be within 2600 degrees. The melting temperature of steel should not exceed 1600 degrees. As for the melting temperature of gold, silver, copper, etc., it is even lower. In addition to the melting temperature, there is also a boiling temperature; under normal circumstances, the boiling temperature of iron should be about 2750 degrees, and the boiling temperature of gold should be slightly higher than 2800 degrees.

However, it is speculated that the temperature of the sky fire must exceed 6,000 degrees, which causes two problems to be overcome.

First, how to keep the outer shell of the heating furnace from melting?

Second, in the process of refining black iron and fine metal, the Tianhuo should not let the metal boil and evaporate and leave any essence. If so, others have long developed substances such as refined gold, mitral silver, red copper, and black iron.

Since it does not evaporate unnecessary substances, there is only one possibility, that is, in a certain situation that we are agnostic, the sky fire not only has high temperatures, but also has ultra-high pressure. The high temperature and high pressure jointly change the characteristics of the material.

Therefore, we must ensure that even if the temperature exceeds 6,000 degrees or even more than 10,000 degrees, the metal cannot boil!"

Tang Rong thought while taking notes: "Young Master is right. The first point is how to ensure that the heating furnace does not melt. I have an idea, which is to use the Samadhi True Fire Formation to arrange a heat insulation layer and then use the Houtu Formation to reinforce it. But this requires the use of seven spirit stones, and it can only last for three days."

"Use!" Li Xian did not hesitate.

"Spirit Stone?!" I heard that there were spirit stones here, Xia Qingqing, Beichen Yuqing, Fang Shijing and Ling Zhifeng widened their eyes. There were spirit stones in the valley in this small marginal area, and it seemed that there were more than seven pieces!

Unfortunately, no one answered their surprise.

After Tang Rong finished speaking, he scratched his head, "But how to prevent the metal from boiling, Master, I can't think of any good way."

Everyone scratched their heads. Of course there is no problem with asking everyone to destroy anything - the accessories of practice are fighting and destruction, but if you want to "protect" something, it will be much more difficult. Restricting the boiling metal is also a kind of "protection" in some ways.

Seeing that everyone was speechless, Li Xian finally thought that there were four newcomers.

However, in the face of Li Xian's first interrogation, none of the four could answer it. To be honest, these four people are still confused now. What's going on?

Seeing that everyone was frowning, Li Xian finally raised his tail, "It is simpler to limit the boiling of metal. This boiling is like rebellion, just suppress it. High-pressure suppression!

However, it is not political pressure, but atmospheric pressure to limit the high pressure of metal boiling.

You can do an experiment, and a simple spell can be achieved. A pot of boiled water will not boil as long as you use spells to wrap around the surroundings and apply pressure."

Everyone immediately tried, and it turned out to be so; when the water boiled, after the surrounding spells were pressurized, the water returned to calm again and the temperature continued to rise.

"But if we refine molten iron up to 6,000 degrees, it would be too dangerous and we could not do this at all!" Tang Rong was distressed. After several test explosions and other things, everyone had established the concept of "test danger".

"You can do this." Li Xian began to draw pictures and explain it. Everyone gradually realized that this could still be done.
Chapter completed!
