Wizard: I brought the wrong system

Yarrow wanted to hide that he knew the speed of light, so when building the abutment, he chose to use the area of ​​the crater to the limit.

In the octagonal mirror scheme, the longest distance needed is the distance between the rotating wheel and the reflection point, and Yarrow set these two points as the right angles to the crater.

Then there is the arrangement of observation points and light sources. It is best to keep these two points in a straight line.

But the straight-line distance of the crater is not enough, and Yarrow can barely pick out a slightly flattened edge.

The measured length of this edge is one kilometer.

Pile up wood next to the light source, build a mirror in the other direction of the light source, and use a few stones as a block in the direction of light output to ensure that a large amount of direct light is released.

This approach is the same as the flashlight.

Then get all the other tedious things done, even with the help of magic tricks, Yarrow finally finished his work when the sky was dark, and he was so tired that he lay directly on the ground.

"Bah, huh huh~ If I had known earlier, I wouldn't have said it in such a hurry."

Yarrow struggled to get up, too tired to lie down and rest.

Because during strenuous exercise, a large amount of blood will enter the limbs to continuously provide energy for the muscles, and the blood flowing into the muscles will flow back relying on the force of muscle expansion and contraction.

If you rest directly after strenuous exercise, a large amount of blood flows into the muscles, but without the help of muscle strength, it is pushed back, a large amount of blood in the limbs will be stagnated in the veins, and the heart must increase the workload , to provide a more powerful squeezing force, and some people with poor heart ability can easily cause heart disease.

At this time, because the blood accumulates in the muscles and the arterial blood decreases, the brain most sensitive to nutrition will suffer from hypoxia due to insufficient blood supply, resulting in symptoms such as dizziness, nausea, vomiting, shock, etc. life.

The best way at this time is to do some small exercises to help the venous blood flow back gradually.

What Yarrow chose was to debug all the appliances.

The debugging process is very simple, that is, light the light source when the octagonal mirror stops, and then go to the observation point to see if you can see the light.

Since neither the observation point nor the light source will change, only the angle of the mirror at the reflection point can be adjusted.

Since the reflection point was directly opposite the crater, it was impossible for Yarrow to run back and forth, so he thought of a way.

Stand a big stone at the observation point. Since the sky is already dark at this time, when the light is successfully reflected and hits the stone, it will be reflected by the stone. Yarrow, who adjusts the angle of the mirror at the reflection point, will know that the adjustment is successful.

……

The mountain pass of this extinct volcano is five kilometers wide, and the area covered by the flat slope is naturally larger. In addition, there are shrubs from the middle, and the lowest end of the mountain is covered with complex trees.

Just outside a hidden tunnel among the cluttered vegetation, Olive noticed the light flickering back and forth above the trees, stood up and looked towards the top of the barren hill.

But at this time, several artificial creations are particularly eye-catching in the night environment after the reflection of firelight.

"Come out, there are people on the top of the mountain!" Olive immediately shouted into the tunnel.

Several people have done division of labor. Before the space was opened, Oliver's main role was to use his fame to drive away other junior students. This is one of the reasons why 'Skinny Monkey' agreed to invite Oliver.

If the middle apprentice comes?

Cold salad, who told Jeddah to only invite him.

'Skinny Monkey' barely squeezed out from the side of the 'Iron Tower', looked in the direction of the light, and asked, "Master Oliver, what should we do?"

The crystal scorpion is an excellent material for undead, not to mention that it can be found from Jeddah's words that this is a mysterious and different space that has been hidden for many years, and it may be full of treasures.

With so many temptations, Olive's subjective initiative is naturally very strong.

Olive ordered: "You guard the entrance first, I'll go over and see if I can expel him."

Not long after Olaf left, the thin monkey's expression changed drastically: "No, the Iron Falcon has come out, go in the iron tower quickly, and immediately activate the concealment circle!"

……

Use double-layer mirrors to re-reflect the light to the eight-sided mirror five kilometers away, and then require the light to be re-reflected to a stone in another direction.

This matter sounds complicated, but fortunately, the cost of trial and error is low, and fine-tuning can be done at any time. It takes a little more time, and Yarrow finally debugged it successfully.

Judging from the final results, the speed of building the abutment was slower than expected, but the speed of debugging was many times faster than expected.

Now he just needs to go back to the observation point and see if there are any minor adjustments to the observation point.

When the observation point can see the reflected light several times, the rotating disk can be turned on to drive the eight-sided mirror.

Results should appear quickly.

After all, when everything is debugged, the follow-up is just to speed up the compass without thinking.

and so……

Why hasn't Wizard Bosco come yet?

If you don't come again, I'm going to start it. When the result is in front of you, don't say I didn't wait for you!

Sitting on the stone at the observation point, Yarrow was blowing the cool night breeze, made a cup of tea with hot melt technique, and drank it one by one, while observing the movement around him.

Now that he has agreed to Wizard Bosco, Yarrow will naturally not break his word.

What's more, the main purpose of Yarrow's experiment was to thank Wizard Bosco. If Wizard Bosco didn't arrive, the experiment would not start.

"Wait a minute, is there someone moving over there?"

Yarrow looked suspiciously at several black shadows halfway up the mountain.

"Wizard Bosco?" Yarrow shouted tentatively.

As a result, the figure turned around immediately, and rushed towards the foot of the mountain even rolling and crawling.

"Isn't it? Who would that be?"

Yarrow was a little puzzled, but he didn't chase after him.

"It may be an apprentice passing by. When he saw the light here, he became curious and came to check."

Wizard Bosco was notorious in the academy, and some students ran away when they heard his name, which was completely normal operation.

The most important thing is that the experimental equipment that Yarrow has refined for a long time is on this mountain. If the experimental equipment is inexplicably damaged because of chasing the passing apprentices, that would be the biggest loss.

slap slap slap...

A sound full of mechanical rhythms came from a distance.

Soon, a huge bird-like black shadow gradually emerged, standing on top of the huge iron bird, who is it but Wizard Bosco?

It's just... why is there someone caught on the bird's claws?

Yarrow looked at him twice, and he was actually an acquaintance... Olive.

"Yaro, hasn't the experiment started yet?"

Wizard Bosco's words brought back Yarrow's gaze.

Yaluo smiled lightly: "Teacher, I'll just wait for you to come and check for me. How dare I start if you don't come."

"You naughty boy," Bosco shook his head happily, "Okay, don't delay, let's start!"
