Wizard: I brought the wrong system.

Chapter 134 Preparation and Debugging (Third Update)
To conceal his knowledge of the speed of light, Yaro chose to maximize the use of the crater's area when constructing the platform.

In the octagonal mirror scheme, the furthest distance required is the distance between the rotating disk and the reflection point, and Yarrow set these two points as a right angle of the crater.

Then comes the arrangement of the observation point and the light source; these two points should ideally be aligned in a straight line.

However, the straight-line distance of the crater was not enough, and Yaro could only barely select a slightly flatter edge from it.

The measured length of this edge is one kilometer.

Stack wood next to the light source, build a mirror in another direction from the light source, and block the direction of light output with several stones to ensure that most of the emitted light is direct light.

This is similar to using a flashlight.

After taking care of all the other tedious tasks, even with the help of magic tricks, it wasn't until dusk that Yaro finally finished, so exhausted that he collapsed onto the ground.

"Pah, haha~ I knew I shouldn't have said it so hastily."

Yaro struggled to get up, too exhausted to lie down and rest immediately.

During strenuous exercise, a large amount of blood enters the limbs, continuously providing energy to the muscles. This blood flowing into the muscles is then returned to the limbs by the force of muscle expansion and contraction.

If you rest immediately after strenuous exercise, a large amount of blood flows into the muscles, but without the help of muscle strength to push it back, a large amount of blood in the limbs will pool in the veins, and the heart will have to increase its workload and provide a stronger squeezing force.

If the heart is even slightly weak, it can lead to heart disease.

At this time, because blood pools in the muscles and arterial blood flow decreases, the brain, which is most sensitive to nutrition, will suffer from insufficient blood supply, leading to hypoxia and symptoms such as dizziness, nausea, vomiting, and shock. In severe cases, it can even endanger life.

The best approach at this time is to engage in some light exercise to help the venous blood gradually return to the heart.

What Yarrow chose to do was to debug all the equipment.

The debugging process is very simple: light the light source while the octagonal mirror is stopped, then go to the observation point and see if you can see the light.

Since the observation point and the light source remain unchanged, only the angle of the mirror at the reflection point can be adjusted.

Since the reflection point was directly opposite the crater, Yaro couldn't possibly run back and forth, so he came up with a solution.

Place a large rock at the observation point. Since it is already dark, when the light is successfully reflected and shines on the rock, it will reflect back. By adjusting the angle of the mirror at the reflection point, Yaro will know that the adjustment is successful.

……

The crater of this extinct volcano is five kilometers wide, and its flat, downward-sloping area is naturally even larger. In addition, shrubs appear from the middle, and the bottom of the mountain is covered with a complex of trees.

Amidst the tangled vegetation, outside a hidden tunnel, Oliver noticed the light flickering above the trees and quickly got up to look up at the top of the barren mountain.

At this moment, several man-made structures, reflected by the firelight, stood out conspicuously in the night.

"Come out quickly, there are people on the mountaintop!" Oliver immediately shouted into the tunnel.

The group had divided up their tasks. Before the space was opened, Oliver's main role was to use his reputation to drive away other junior students, which was one of the reasons why 'Skinny Monkey' agreed to invite Oliver.

What if an intermediate apprentice arrives?

Well, whatever. That's what Jeddah had to do to get him to come.

Skinny Monkey squeezed out from beside Iron Tower, looked in the direction of the light, and asked, "Lord Oliver, what do we do?"

Crystal scorpions are excellent materials for undead, not to mention that from Jida's words, it can be found that this is a mysterious alternate dimension that has been hidden for many years, and it may be full of treasures.

With so many temptations, Oliver's initiative was naturally very strong.

Oliver instructed, "You guard the entrance for now. I'll go over and see if I can drive him away."

Not long after Olaf left, Skinny Monkey's expression suddenly changed drastically: "Oh no! The Iron Falcon has come out! Iron Tower, get inside quickly and activate the concealment array immediately!"

Using a double-layered mirror, the light is reflected back to an octagonal mirror five kilometers away, and then this light is required to be reflected again to a rock in another direction.

This matter sounds quite complicated, but fortunately the cost of trial and error is low, and fine-tuning can be done at any time. Even if it takes a little more time, Yaro eventually managed to debug it successfully.

In the end, the base station setup was slower than expected, but the debugging process was much faster than anticipated.

Now he just needs to return to the observation point and see if any minor adjustments need to be made.

Once you can see the reflected light several times from the observation point, you can turn on the rotating disk to drive the octagonal mirror.

The results should be available soon.

After all, once everything is set up, all you need to do is mindlessly accelerate the compass.

and so……

Why hasn't Wizard Bosco arrived yet?
If you don't come soon, I'm going to start this. Don't say I didn't wait for you when the results are in front of you!

Sitting on a rock at the observation point, Yaro enjoyed the cool night breeze, brewed a cup of tea with his heat-melting magic, and sipped it intermittently while observing the surrounding activity.

Having already promised Wizard Bosco, Yaro naturally wouldn't go back on his word.

Moreover, the main purpose of Yarrow's experiment was to express his gratitude to Wizard Bosco. Since Wizard Bosco did not arrive, the experiment would not have started.

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

Yaro looked at the several dark figures halfway up the mountain with a puzzled expression.

"Bosco the Wizard?" Yaro called out tentatively.

As a result, the figure immediately turned around and scrambled down the mountain.

"Isn't that right? Then who could it be?"

Yaro was somewhat puzzled, but did not pursue the matter.

"It was probably an apprentice who was passing by. He saw the light here and came over out of curiosity."

Bosco the wizard was infamous in the academy; it was perfectly normal for students to run away at the mere mention of his name.

Most importantly, all of Yaro's experimental equipment, which he has been refining for a long time, is on this mountain. If the equipment is damaged inexplicably while chasing after passing apprentices, that would be the biggest loss.

Patting, patting...

A mechanical, rhythmic sound came from afar.

Soon, a huge bird-shaped black shadow gradually emerged. Standing on the giant iron bird, who else could it be but the wizard Bosco?

But... why is there a person caught in the bird's claws?
Yaro glanced at him and realized it was someone he knew... Olive.

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

Bosco the wizard's words drew Yaro's attention back to him.

Yaro chuckled and said, "Teacher, I've been waiting for you to come and oversee things for me. How can I dare to start without you here?"

“You slippery little rascal,” Bosco shook his head with a laugh. “Alright, enough of that, let’s get started!”
