You won’t be afraid if you learn mathematics, physics and chemistry well and cultivate immortality

Even if they complete the task of handing over the specific matters of convincing people to the Book Club to Hao Youqian and Zheng Daqian, the matter can be considered to be over for the time being.

To look at something recorded in a small notebook, you have to use that huge magnifying glass.

This is intended to be used to concentrate light and absorb purple energy. I wonder if it is feasible?

Anyway, experiments don’t cost money.

There are also glass products that were promised to many people last night, so we can solve them all at once.

There are many places in Majia Village that need to be installed with glass to let in light.

Then hurry up! It's not an advanced skill anyway.

All the troublemaker trio need to do is continue to carry their weight and move forward.

Tie Chui entrusted Murong Wan'er to Ma Yumei to take care of her. The advantage was a half-length mirror.

I guess I won't wake up so soon this time. After all, I slept for three days when my vocal cords grew last time. This time it's a complete remodeling and repair, which may take longer.

The three of them decided to go back to the blacksmith shop after discussing it.

This time I am preparing to tinker with a huge magnifying glass.

On the way, we found a small river beach and collected a lot of fine sand.

The blacksmith shop is still the same as before, and you do what you need to do.

It was originally planned to be fired in the blacksmith shop, but it was so busy inside that Musk was embarrassed to mess around here.

After all, let's try it out in a house-sized one.

Since it doesn't work here, then look for a place behind the mountain.

As luck would have it, I thought it would be nice to have a relatively open area where I practiced archery last time.

The lucky tree that was knocked into two parts actually sprouted new branches from its roots when spring came.

Then next to it, level the ground and build a big furnace!

These things are extremely simple for cultivators.

Anyway, it was only used a few times, and it was not intended to be a permanent tong stove. It did not require anyone's help. It took the three idiots about an hour to complete it.

Don't do it again and again.

The three of them were engaged in business with their heads covered.

Let’s start burning glass!

Backfired.

Two days passed and they experienced several failures. Even with their ability, the huge convex lens was only the size of a door frame.

This is the limit of their control.

The weight of such a large convex lens is not light, so we can only accept the reality helplessly.

Since this is the biggest, let’s try the effect! A huge iron frame was built to prop it up.

The sun was just right at this time, and the temperature in the light spot was still quite high.

Throw a dead branch on the side at the center of the focus point, and it will start to smoke and catch fire after a dozen breaths.

This is awesome, as a chef with a hammer, he took out a spirit animal leg from the storage bag, skewered it and grilled it underneath.

It's energy-saving and environmentally friendly, which is great.

Not long after, the grilled meat is freshly baked, with oil dripping from the oven. Tear off a piece and stuff it into your mouth. It has a unique flavor baked in the sun.

There is less of a smoky smell and more of a sun smell.

Tie Hammer said happily: "This is good. You can cook without burning a fire."

Musk rolled his eyes and said, "What a fart. Without sunlight, it's just a decoration."

And the next moment a new idea flashed in his mind,

Just once when I was occasionally watching short videos, I saw a blogger using a satellite cauldron to make a solar water boiling artifact.

If you get a shelf big enough and put enough small glass mirrors on it, that won't be enough.

The class representative said: The principle of solar water heating is to use the reflection principle of glass lenses to use countless small glass mirrors to refract all sunlight from a large area and concentrate it in a small area to increase the temperature. It may be necessary to turn the device from time to time. After all, the earth is rotating and revolving every moment, and the angle of the refracted light will gradually deviate slightly.

Musk thought about this, took out a pen and paper from the storage ring, and began to calculate the area and arc.

Fortunately, I am a science student. ???

3.……. This pi calculation is really stupid. ??

Seeing Musk writing and drawing on the side, the two veterans couldn't understand it anyway, so they immersed themselves in their careers.

After all, many places in Majia Village and Blacksmith Shop need to be replaced with glass windows and roofs.

After careful calculation three times, I finally got the correct data. The calculated answer showed that a semicircle with a diameter of about ten meters would require palm-sized lenses, which cost thousands of dollars.

There is no other way but to work hard!

The two veterans flipped flat glass, while Musk flipped a slightly curved glass mirror according to the number.

The three of them ate some roasted spiritual meat when they were hungry, drank some spiritual wine when they were thirsty, and meditated and took a break when they were sleepy. They didn't have any time to spare.

Fortunately, I am proficient in all forging techniques, stand on the shoulders of giants, and have a general idea. Success is only a matter of time.

After two busy days, Musk and the three finally refined all the required glass products.

As for the convex lens you made, you can’t waste it, just repurpose it slightly.

The whole concave lens, build a very large telescope for fun.

Isn't this an astronomical telescope?

Theoretically speaking, being able to see planets in the outer sky is a veritable clairvoyance, right?

The three of them hit it off immediately, so let’s do it.

Anyway, there is plenty of sand, so just bake it and dump it.

This move is directly like a super-large clairvoyant, turned out to be.

This is amazing, but it’s a bit heavy and requires two people to lift it to see it.

You can clearly see the stars outside when facing the sky.

Then the three of them were curious about how far this thing could see.

It was just too heavy, weighing almost two thousand kilograms. It was carried tremblingly by two old men, with Musk dragging behind, and the three of them worked together to lift into the air.

At a height of 100 meters, you can see an unobstructed view when you look down. Today is a good day, the wind is sunny, and everything is growing.

Through this simple version of a very large telescope, you can clearly see scenes dozens of miles away.

The three of them took turns to experience the feeling of seeing for more than ten miles.

However, it was difficult to see clearly at a farther distance. To solve this small problem, the not-so-difficult technology of zoom flashed into my mind.

Then under Musk's command, the three of them made another change, changing from a fixed focus to a telescopic zoom monocular telescope.

It was still carried by two veterans, and Musk watched the test results.

This time, the clarity has indeed improved. In the distance, there are mountains, ravines, and ancient trees. From time to time, you can see rare and exotic animals playing.

Musk continued to look farther away, and he could see everything hundreds of miles away, and he continued to look farther away.

By coincidence, in my field of vision, I actually saw two demonic beasts that were almost as big as a house. They were mainly the trunks of the ancient trees in the sky, and they looked a bit underwhelming next to them.

What's more important is that they are having sex there! Hey! ???

What's even more coincidental is that it seems that they sensed that something was snooping and locked their eyes on Musk's direction.

Musk also clearly saw the fierce and angry look in the eyes of the male beast.

The giant beast struck by lightning that night in Wolong County a year ago suddenly flashed through his mind.

The body shape and skeleton are very similar.

Damn it! I was so frightened that I shivered! Quickly greet the two old men, the wind is tight!
