An Tianhan still has to go to the city lord's mansion to do errands. Song Xiayang's brother and sister want to accompany their cousin.

An Kang, An Yiyu and the others returned to Anfu, and they were naturally very happy.

An Yiyu and the others had no doubts about why Ankang was not injured after being struck by lightning. Because Ankang didn't change from a fool to a smart person after being struck by lightning, and he also learned spells.

But Nangong Man is different. She knew that the thunder drawn from the sky and the thunder in the "thunder pool" in the Ita galaxy that Ankang mentioned were not the same concept at all. Is the heavenly thunder a hundred times more powerful than the thunder in the "thunder pool"?

After everyone left, Nangong Man went to Ankang's room and asked, "What's going on with this thunder?" Can you really withstand the thunder bombardment? ”

An Kang smiled "hehe": "Senior sister, guess? ”

Nangong Man shook his head.

An Kang considered how to explain the concept and principles of electricity to Nangong Man, a woman born in the Song Dynasty.

In the 21st century, even kindergarten children can understand the knowledge of electricity. The problem is actually very simple, the reason why people are injured by electricity is because the strong current is far stronger than the body's bioelectricity, far beyond the range of the body can bear.

Although the lethality of electricity is very strong, human beings have invented the transformer, a good thing, which can change the intensity of the current at will. Although the structure of the transformer is complex, the principle is nothing more than changing the voltage and current through something like resistance.

In the current era, Ankang can't make a transformer, but it's still possible to make a copycat version of the resistor.

After receiving the challenge letter from Song Xiachen, An Kang thought of the way to deal with that spell master was to attract thunder from the sky. Of course, this idea was not sudden, but was considered when discussing with Nangong Man how to convert thunder and lightning into the Force and then cause an earthquake.

In the hours before rushing to the martial arts arena to participate in the competition, Ankang was seizing the time to do two experiments, one was the electric introduction experiment and the other was the transformer experiment.

Electrification is comparatively easy. Because Ankang has experienced countless times in the "thunder pool" of the Ita system, he knows how to direct electricity to his designated direction.

At noon, when the thunder and lightning were more concentrated, Ankang successfully led the thunder and lightning to the garden of Anfu.

He stuck a brass pole in the lake in the garden. The copper rod became the shortest point of distance from lightning on the vast plane of the lake. After Ankang uses the method of the Force to induce electricity, the success rate of lightning hitting the copper rod can reach 100%.

Although the electric induction experiment is easy, the voltage transformation test is much more troublesome.

To transform the voltage, you must do resistors. In the past, when Ankang was in physics class, the resistors were made of pencils. Where to find a pencil in this era?

To make a resistor, you have to use a special material, which does not conduct electricity like metal, nor insulate like plastic, and needs to let a small amount of charge pass through and block most of the charge.

Ankang thought of the metal ore that his physics teacher had mentioned. The metal in metal ore is electrically conductive, whereas the stone is not insulating. Metal ores can conduct a small amount of electricity.

Among the metal ores that can be used as electrical resistance, quartz and tin ore, which were common in this era.

Quartz stone is often used as a stone and mirror, and tin ore is a necessity for the manufacture of bronze objects.

So after offering sacrifices to the heavens with a few chickens and dogs, Ankang finally made an effective resistor out of tin ore and tied it to the handle of a copper sword.

In the duel with Shen Yang, Ankang let Shen Yang strike first. It's not that Ankang is holding a shelf and holding it up, but because there was no thunder in the sky at that time!

Since he knew that his fire-based skills were not Shen Yang's opponents, there was no need to consume a small amount of Force power for no reason. Try to avoid injury on the premise of waiting for thunder.

Just as the thunder struck, Ankang, who was standing next to the copper pipe supporting the tent, led the thunder to the copper pipe, and then used the copper sword to lead it to himself, and quickly converted the electricity into the Force.

With the help of the power of thunder and lightning, he struck hard, and only then did he break through Shen Yang's spell protection, causing him fire damage that he could not resist.

"This is the whole process of leading the thunder." An Kang said to Nangong Man.

Although Nangong Man had observed Ankang's process of inducing thunder and lightning in the garden, she didn't actually understand the principle, and she didn't think that she could use it directly by directing the thunder into the lake in the garden.

However, although she does not understand the principles of electricity, she understands at least one thing: it is feasible for Ankang to convert the thunder and lightning in the sky into the Force, and then transmit the Force to her through the Force Transmitter, and then use her earth-based skills to cause earthquakes.

Ankang agreed to compete with Shen Yang this time, not so much to fight for the family's reputation, but actually to rehearse for the earthquake that would occur in a few days.

Nangong Man listened to An Kang's explanation, and his heart was surging.

Although the young man in front of her said that he had the shadow of his own year, he was far more persistent and better than herself. As a savior, he failed, not only was he far from saving the planet, but he couldn't even complete a small test like the fall of a meteorite.

With this young man's ability, he couldn't do it, but he used infinite possibilities to achieve this goal. I'd rather die to accomplish this goal.

The so-called aspiration is the young man named Ankang in front of him.

Nangong Man once made up his mind to assist Ankang in completing the task of saving the world, and now this determination is even stronger. Compared with herself, Ankang has a more chance of saving the world.

No, not a possibility, a necessity.

"Senior sister, let's start practicing now. Take advantage of this wonderful weather. ”

Is the weather wonderful? Of course wonderful, with dark clouds and thunder and lightning. It doesn't get much more delightful than that.

Ankang had already prepared all the tools to practice being struck by lightning. He took Nangong Man, An Yiyu, and An Fu to the garden to conduct human lightning experiments.

On this day, Ankang has experienced several experiments, and he has also conducted actual combat in the martial arts arena, so he is naturally full of confidence. But his cooperation with Nangong Man was the first time after all, so he was extremely cautious about the use of tools.

The tin ore used as a resistor is not a modern precision resistor, and its chemical and physical properties are not stable. So every experiment actually involves a certain amount of risk.

However, it is necessary to ensure that every practice is carried out in place, and the number of exercises is minimized.

Ankang asked Nangong Man to stand a foot away from him, and he himself stood by the lake with a copper rod tied to tin ore, waiting for the next thunder to come.

In the pouring rain, a man and a woman stood quietly like this.

In the pavilion, An Yiyu and An Fu could only look nervously. Couldn't help in any way.

After a long time, there was still no thunder and lightning.

An Kang looked at the sky, and the dark clouds seemed to be showing signs of dispersing. He was so anxious that he didn't know how long this would last.

After all, he will only lead mines, not make mines. If there was no thunder in the sky, he would not have been able to create thunder and lightning out of thin air.
