Building a generator to ward off the tide of beasts is a crazy idea that comes up from the cold clouds.

If there is a magnet and a copper wire, you can use electromagnetic induction to send electricity, which is not a high-tech thing in the cognition of earthlings.

Is the man in junior high school physics named Faraday or Lavoisier?

It was the invention of the theory of electromagnetic induction that brought mankind into the era of electrification.

In his previous life, Han Tianyun had a headache when he saw physics, and he scored more than thirty points in every exam, which can be said to be a veritable scumbag.

But I remember the physics experiment class where the teacher gave them a small magnet, some copper wires, a cardboard tube, a simple hand-cranked generator, and a small light bulb.

Han Tianyun is not interested in physics knowledge, but he likes this kind of interesting experiment very much, not only does it himself, but also does it several times at home after returning home from school, but he is very proficient in making this small generator.

Just a few days before the crossing, he also expressed full disdain and doubts on Douyin about a video of a light bulb lit by tying copper wire with a U-row magnet.

Even as a loyal reader of time travel, he has seen people who went back to the Tang Dynasty to invent soap, and some people who went back to the Ming Dynasty to invent the steam engine, but he has never seen time travel back to generate electricity.

At that time, he secretly complained that he could directly enter electrification, but he had to go through the whole process of industrialization, and the authors were tired enough.

But now that I think about it, maybe those predecessors haven't encountered spiders that can spit copper wires, and natural magnets are probably more difficult to find!

After all, if I hadn't seen the magnet and copper wire at the same time, I would never have thought of generating electricity.

"So I'm going to travel to this other world to generate electricity? haha. Han Tianyun couldn't help but get excited, feeling that from now on, he was about to start on the road to becoming a god by pretending to be forced to slap his face.

"Sure enough, memory and knowledge are the biggest golden fingers of the travelers, and the seniors are honest and don't deceive me!"

Han Tianyun looked at the waterfall roaring down the cliff to the west, his small black eyes flashed, and he had many ideas about his plan for the generator.

He decided to build a hydro generator, use the impact of the waterfall to drive the turbine to rotate, convert kinetic energy into electricity, and build a shelter surrounded by electricity by the cold pool, if successful, he and the nurse can stay away from this demon tree as soon as possible.

With a goal, there is naturally passion, but if you want to make a hydrogenerator with your bare hands, this difficulty is probably much more difficult than that of the Australian brother to make iron with his bare hands.

So you have to take it one step at a time, do some preparation first, and try to find opportunities to make a few handy tools.

All night, he was busy under the giant tree.

He and the nurse separated the copper wires from the horns, moved them back into the cave, and moved the magnetic thunder wedge not far from the entrance of the cave.

According to his assumption, with the existence of this strong magnetic thunder wedge, once those poisonous spiders appear next time, not only will they not be able to get close to the hole, but they will also be able to take this opportunity to collect some more copper wires.

There are also those hoofed and clawed animals that have horns more than a meter long, and their movements may also be affected, and they can no longer attack the cave.

In the second half of the night, he found the trunk of the tree that had been struck by lightning three days ago and had fallen on the edge of the stone field, and all of them were left in place, although the branches and leaves had been eaten up by the previous insect tide, but the bark and trunk were still intact.

This is really a surprise for Han Tianyun.

The smooth trunk can be used as a support for generators, and the intact bark is also very useful when cut off.

In particular, the bark of this giant tree is not afraid of fire, and it is extremely flexible, which not only allows the nurse to use the bark to make a few bark clothes to cover her body, but can even be used as a wrap to prevent the short circuit of copper wires.

It took a lot of effort until dawn for Han Tianyun to drag all the tree trunks that could be moved back to the cave, and piled them up haphazardly to build a rough fence.

I believe that with the blocking of these tree trunks, in the next beast tide, I and the nurse will be much safer.

After doing this, he took two golden fruits, and while eating, he walked along the trail to the cold pool under the waterfall, ready for a thunderstorm once every three days.

But strangely, the weather seemed to be a little different today, he waited for a long time, there was no thunder and lightning on the gloomy sky, and the pouring rain did not come as scheduled.

"The thunderstorm is gone?" Han Tianyun finally came back to his senses, and when he looked closely, he found that there was faint light on the sky dome from between several black clouds, which seemed empty, not as dark as ink in the past.

In addition, the air was devoid of the usual violent winds, and the earth was unusually quiet, and nothing could be heard except the roar of the waterfall.

After waiting for a long time, I saw a few black clouds slowly drifting to the east, and sunlight shining through the clouds on the top of the half-broken giant tree, a sunny scene.

More than half a month later, in the early morning, the expected thunderstorms, gales, and showers were all cancelled......

Estimating that the usual time for thunder and lightning quenching had passed, and confirming that the thunderstorm would not come again, the cold clouds hurriedly returned to the tree.

Sure enough, there were no thunderstorms, the stone ground was smooth, and not a single golden fruit fell.

Squatting on the stone ground and waiting for a long time, the beast tide that came as scheduled did not appear for a long time.

His mood is a little complicated, and for more than half a month, he has been waiting for some different changes.

If it was said that the muffled thunder that suddenly appeared three days ago and broke the stem at the top of the demon tree was this kind of change,

Then the sunny weather at the moment, the beast tide that no longer appears, of course, is also.

Han Tianyun didn't know what such a change meant, but he could only accept his fate, because he had no choice.

But without the beast tide, he would have had some time to start preparing the grand plan for the generator.

But since there is no beast tide, is there still a need for his plan to continue?

Shouldn't you explore the forest first and see if you can leave this hellish place?

What's more, the big tree no longer drops fruits, and neither he nor the nurse's rations can survive tonight, and if he wants to survive and enter the forest, I'm afraid it's his only choice.

Thinking of this, Han Tianyun drilled back into the tree hole, drew a beast horn more than one meter long as a weapon, and appeared on the meadow to the north of the big tree.

For safety, he left the nurse in the hollow of the tree and decided to explore the path himself.

The nurse did not have much objection to his decision, but told him in sign language: "No matter how far you go, you must return to the hollow of the tree at noon." ”

Standing at the end of the meadow, Han Tianyun stared at the forest in front of him, remembering the Black Forest in a certain movie in his previous life.

It was a strange forest, with an eerie gray-black mist hanging over the forest, making it impossible to see the scene from a few meters away, and an oppressive aura greeted the face, making it difficult to have the courage to step in.

"This is also a magical curse land?" Han Tianyun beat a drum in his heart, hesitated for a long time, and then slowly touched into the forest.

In order to survive, he actually had no choice at all.

As soon as he stepped into the forest, a damp mist greeted him, which made the pores of his whole body open instantly, and his body was suddenly immersed in an indescribable comfort.

It was like suddenly falling into a hot spring.

But this also made Han Tianyun's heart wake up, and he hurriedly retreated to the meadow with an arrow step.

Then that feeling quickly faded again.

After a few attempts, he found that as long as he entered the forest, the temperature and humidity seemed to be very different from those on the meadow, but it seemed that there was no harm to the body.

The forest was very dense, and the ground was thick with fallen leaves, coupled with the mist, he could only see the situation within four or five meters in front of him, which made Han Tianyun more cautious, and almost moved towards the forest step by step.

But even so, he quickly ran into trouble.

There was a loud bang, and a giant python more than a foot tall suddenly stood up under the thick dead leaves, swallowing scarlet letters, blocking four or five meters in front of him.

Fine beads of sweat appeared on Han Tianyun's brain, this giant python was golden all over, and every beast tide would appear on the stone ground, and as soon as it appeared, it was almost the strength of sweeping a piece.

With his current thin and small body as thin as a bamboo pole, there was no possibility of killing it.

But he couldn't turn around and run away, and the python's high-spirited head tilted back slightly, as if it was ready to strike a fatal blow at him at any moment.

"At times like these, you have to be calm and never turn around and run. He secretly admonished himself in his heart, the horn in his hand was raised slightly, and he made a chopping gesture, his eyes staring at the head of the giant python motionlessly.

At this moment, a gust of evil wind came from behind him, and Han Tianyun secretly screamed badly, and rolled out to the side with a dodge.

Syllable!

With a loud bang, a python tail two or three meters long and the thickness of the bowl slapped at Han Tianyun's previous position, hitting the dead leaves all over the sky, if he hadn't reacted fast enough, this one alone would probably have stunned him.

Unexpectedly, the giant python had considerable wisdom, and used the python body to attract the attention of Han Tianyun, but it took the lead in attacking with the python tail hidden behind him.

The cold clouds rolling on the side had their hair standing on end, and they bounced on the ground with their horns and pounced towards the grass in front of them.

Hula!

It seemed that everything was expected by the giant python, and the grass in front of the cold sky cloud suddenly became dusty, and a python the size of a bucket rose from the soil and instantly enveloped him......
