Chapter 20: Black-Dragon Jade

For most people, a 220-volt alternating current was extremely dangerous.

Although Feng Jun majored in arts in university and he hadn't suffered great pain just then, he knew it very well.

Therefore, he was quite cautious when he did the test.

He used the back of both hands to carefully touch the bare copper core. It was said that a man's hands would subconsciously clench once they felt danger, which was regarded as a stress response of the human body.

If he held the copper core with his palms, it would be highly risky.

In fact, most people would use the back of their hands to test whether a glass of water was hot or not.

The back of one's hand would subconsciously move away the second it felt danger.

The back of Feng Jun's left hand first touched the bare copper core followed by the back of his right hand.

The next second, both of his hands bounced away.

In fact, this was also because he was overly nervous.

However, he was quite satisfied with this test, because he really felt the electric shock and his whole body was numb.

It was just numb for a second, and it was to an acceptable level.

He tried it twice with the back of his hands and found no problem with it. He felt a little numb, but it was really just numb. It was far away from his endurance limit.

Then he tried to turn his right hand over and used one palm and one back of his hands.

Afterward, he tried two palms.

When he used both palms, Feng Jun didn't grasp the wire tightly. He lightly placed the little finger of his left hand on it just like when he found the magical stone.

As an adventurous man, he unexpectedly found the same feeling of touching the magical stone, and his left hand was hot while his wrist was cool.

However, the heat was extremely subtle, not as much as one-thousandth of that of the magical stone, or even less than one-ten-thousandth.

To his surprise, the 100-amp switch wasn't flipped off.

Feng Jun didn't bother to think about the reasons this time. He took himself as the protagonist in a novel, and a protagonist always had good luck.

He had experienced many unbelievable things after all, and was already used to it.

Nevertheless, he soon discovered the heat gradually increased as the little finger of his left hand pressed the wire harder and harder. As time went by, even the sound of the generator changed slightly.

The closer the contact was, the more power the generator would output.

Now the protection switch at the output of the generator was 100 amps. Even if a 50 kW generator was connected to a 200-amp switch, it wouldn't be overloaded under normal circumstances.

Feng Jun had no intention to try that because he was too careful and thought that a 100-amp current was very strong.

If he destroyed the transformer of the city electricity, it was a public facility anyway, but this generator was his own property.

Feng Jun finally found out with joy that he had found the right way to charge himself. Instead of using a mobile phone, he could directly touch 220-volt electricity with his hands.

However, it didn't take long for him to get frustrated. The charging speed was too slow.

He charged for almost an hour and used about 20 kWh, but the mark of the stone ring on his wrist didn't change at all.

He was sure that the stone ring mark had absorbed the electricity, but he couldn't see any changes.

Since he couldn't see any changes, it meant that the energy wasn't enough.

Feng Jun decided to be patient and waited for a longer time. As long as he found a reasonable way to replenish energy and the plan could be implemented smoothly, all the waiting would be worthwhile.

He was a person with persistence; otherwise, he wouldn't be able to get a double degree smoothly.

As long as there were a goal and a way, he was definitely one of the people who could persist in reaching the goal.

However, after twenty hours, he had the idea to quit, because it was really slow.

During this period, in addition to sleeping and eating, he kept on charging for almost twelve or thirteen hours.

The increased energy was too little to count. According to his estimation, even if he tied his hands to the wire, he could only charge one energy point at most.

He had kept charging for 24 hours and every hour cost about 16 kilowatt-hours of electricity even if the current was only 80 amps. After 24 hours, it could be about 400 KWh.

Feng Jun needed at least five energy points to enter the space once. In other words, he had to charge for five days and five nights to get in and out of the space once.

He needed more energy if he wanted to carry stuff with him.

"Now I know why the transformer exploded." Feng Jun sighed sincerely and said, "This way of charging is too expensive, and I can't afford it."

A diesel generator was certainly convenient, but the cost was too high. If a 50-kilowatt generator worked economically, the cost of one kilowatt-hour of electricity was more than one yuan.

He had to pay over four thousand yuan for 2,000 KWh in that case!

Feng Jun believed that he definitely could make money and his first pot of gold by smuggling, but the problem now was that he was really poor.

His capital chain could easily break if he wasn't careful.

He already used the thirty thousand yuan Wang Haifeng paid him to buy a generator and various materials. He even used his salaries.

He bought a new phone and rented an apartment afterward, so he only had less than four thousand yuan in his pocket now.

There was over ten thousand yuan in his bank card, and all his cash was less than twenty thousand yuan. He needed money to purchase goods in the future.

He was reluctant to spend four to five thousand yuan on diesel fuel at this time.

Besides, he felt too embarrassed to borrow money from Wang Haifeng after leaving the club.

Feng Jun felt cornered and didn't know what he could do now. He hated to contact his parents only for money. He was an adult after all, and he shouldn't ask his parents to continue to sacrifice themselves for him.

Thinking of the big problem, he couldn't help but use greater force with his hands, and the protection switch tripped at once.

I need to have a break.

Feng Jun stood up and stretched his sore arms, then walked out of his room.

This was the second time that the protection switch tripped. Because he had been carefully controlling the generator, the generator wasn't damaged. After all, the redundancy was more than a double.

The problem was that it cost too much time to charge. Feng Jun put his hands in his pockets and walked out with his mind wandering about. He could only get five energy points every five days and five nights.

If he wanted it to work for a long time, he could only charge five points in 10 days, because his body needed enough rest.

In that case, he had to charge for at least 30 days in order to carry goods into the space once.

Even if he didn't consider the cost of diesel, he could only carry goods into the space once a month, and he had to charge during the rest of the month.

Upon thinking of that, Feng Jun was quite upset. He was still young and the time was good. He still wanted to enjoy his life and he couldn't go to a bar with a one-person high generator.

The charging time was too long, which was the reality that he really didn't want to accept. Even if he could make a fortune in the future, this defect would seriously affect the quality of his life.

An idea dawned on Feng Jun that he could probably try an electric current of 380 volts.

The next second, Feng Jun shook his head and gave up that idea because he didn't want to die.

It was much stronger than 220 volts, and the arc could already hurt people before he touched it.

Feng Jun wouldn't refuse to take a risk, but it must be worth trying. Ten days had passed by, and he wasn't the poor young man anymore. With the adventure, he should enjoy and cherish his life. In that case, he didn't want to take unnecessary risks.

Anyway, he only needed to think of a better way.

He could probably find a place to use the city's electricity without anyone noticing him.

Thinking of this, Feng Jun walked out of the gate. It was only a little past 5 pm, and he rode straight to a jewelry store, "Li Dafu".

"Li Dafu" was a famous jewelry brand in Zhengyang City. It had branches in other cities, but didn't expand to another province.

Although there were many international jewelry brands in Zhengyang City as a quasi-provincial city, most local citizens preferred "Li Dafu" than other famous brands. Other jewelry businessmen even complained that the local citizens disliked brands from other places.

Feng Jun went there to see rubies. If there were other high-quality jewels, he wouldn't mind looking at them too.

Attendants in "Li Dafu" were quite enthusiastic, and none of them disdained Feng Jun for his shabby clothes.

They knew that most of their customers were local citizens.

Almost every local couple needed to buy a set of "Li Dafu" jewelry for their wedding.

Although the store was about to close today, a saleswoman still served Feng Jun with enthusiasm.

Feng Jun walked around in the shop, but he failed to have the feeling that would make his wrist hot. Even if he knew the ruby in the wilderness was definitely not a ruby on Earth, he still felt quite disappointed.

In the end, he asked the saleswoman to give him two rubies and a piece of jadeite. He then felt them up close again.

Unfortunately, he still felt nothing.

Seeing him silently handing back the pendants, the saleswoman said to him in a low voice with hesitation, "If you are not particularly picky about quality, there is an antique shop next to our store. It has a new batch of black-dragon jade pendants, which is relatively affordable."

Black-dragon jade? Feng Jun's eyes lit up at once. He had heard of it before.

Black-dragon jade was quite popular these years even though it was just a publicity stunt. It used to be sold by ton, but now it was sold by gram.

Anyway, he didn't know how to appreciate jade.

It didn't matter actually. In web novels, jade always had all kinds of unbelievable effects.
