"What is this? Stealth? ”

Xu Qingge blinked his eyes, the pet beast had indeed disappeared completely.

But this is unreasonable, the stealth of the pet beast is either similar to camouflage clothing, but it is difficult to see, and it is not really "stealth".

Either the dark pet beast uses the shadow to sneak in, but the principle of the shadow is to use the dark energy to create a shadow and then infiltrate the shadow itself.

Because of this, attacking the shadow is actually destroying the shadow by destroying the dark energy that blocks the light.

Light pet beasts also have similar operations, but Xiao Ruoruo's move looks different from any known pet beast move.

If you take the evolutionary chain of the small sharp fish to the blazing sun fish, it can indeed evolve into a rare light pet beast, which means that it may have light qualifications.

But if this is a new evolutionary route, according to the difference in appearance, it should be two kinds of pet beasts, and there should be a difference.

"Ruoruo? No, master, this is a bubble. ”

"Do you remember when you were at our grandfather's house, you accompanied the boss upstairs to bask in the sun."

"Then when I found Boss Sunshine's body, it became colorful."

"Sunlight can also become colorful when it penetrates water bubbles, so I try to play with sunlight."

"But it was too tiring to keep the blisters intact all the time, so I tried to reduce the energy consumption."

"I didn't expect the blister and a pot of flowers behind it to disappear, but I could still feel the blister."

"Master, why is that?"

Xiao Ruoruo twisted and crossed her fins, although she could use this strange move, but she didn't understand why.

Xu Qingge took a step to the left, and she immediately saw Hall.

There is only one side of the stealth, and what is obvious is obvious, this is the lighthouse lens.

The continuous surface of the lens partially "collapses" into a plane.

In section, its surface consists of a series of zigzag grooves, with an elliptical arc in the center.

Each groove has a different angle from the adjacent groove, but concentrates light in one place, creating the central focal point, which is the focal point of the lens.

Each groove can be thought of as a small individual lens that adjusts the light to be directional or concentrating. This lens is also able to eliminate some spherical aberrations.

Xiao Ruoruo's trick of using water to simulate the mirror is indeed beyond his imagination.

Although this move can only be laid between two pairs, it has little effect on multiple enemies.

And due to the reduced output of water energy, the defense is not as good as the original blister.

However, since the battles between the beast masters are often one-on-one, this move has a lot of merit.

Unless it's a move like "detection" or has a particularly sensitive sense, it can see the light that is scattered.

Otherwise, it can even be said to be invincible.

It's just that the knowledge of the lighthouse lens, how to talk to Xiao Ruoruo.

Xu Qingge was worried in his heart, the Fresnel lens was the knowledge of elementary school, and it was too early for Xiao Ruoruo.

I've been specializing in dietitians since junior high school, and I've basically returned optics to my teachers.

The light passing through Xiao Linglong will indeed show colorful colors, but through this, you can make a Fresnel lens, is Xiao Ruoruo an optical genius?

She felt that her head was big, very big, no wonder the high-level beast masters were basically transformed from other professions, and the attributes of the beast were related to the original job.

It turns out that this can also help pet beasts understand the moves?

Xu Qingge can only use the most superficial knowledge he can understand to explain for Xiao Ruoruo.

"Light is a type of energy, and the part that travels through the water attenuates the light."

"When it passes through water and air, it bends if it doesn't come in vertically."

"But since light doesn't bend when it comes in vertically, the smaller the distance the light can get from one end of the blister to the other, the better."

"In this way, if you change the angle of refraction at the other end, you can change the angle of the light."

"Do you understand?"

A cold sweat broke out on Xu Qingge's back, and she had already seen Xiao Ruoruo's puzzled expression.

"Ruo Ruo. Master, I don't understand. ”

Xiao Ruoruo shook her head, there is no way, she is just a baby.

"So, do you know why objects have colors?"

Xu Qingge thought about breaking her head, she suddenly found that she didn't need to explain the principle of the Fresnel lens, as long as she could tell the principle of stealth.

"Ruoruo?"

Xiao Ruoruo shook her head again, learning moves, it's really a difficult thing.

"You've got it."

Xu Qingge put her hands into the lotus pond, bowed a handful of water, and then she threw the handful of water to the ground in the distance.

The lake fell to the ground with a clatter, shattering into countless pearls.

"Look at the shape of the water, and so does the light."

"When sunlight hits something, it will bounce like a drop of water, but its movements are more regular."

"This move is actually using water blisters to adjust the light that bounces off one's body."

"It is precisely because of this that the distance between myself and the blister is required."

Xu Qingge felt that he was extremely contradictory, and it still sounded complicated to say this.

But Xiao Ruoruo was already staring at his fins and began to think.

After about a dozen seconds, the water shield that had stopped in front of Hall disappeared.

Xiao Ruoruo clenched the fins again, and she began to stealth herself.

Unlike before, this time's "stealth" is not simply one side.

No matter how Xu Qingge walked around Xiao Ruoruo, she couldn't tell where Xiao Ruoruo was at all.

However, Xu Qingge knew that Xiao Ruoruo was there and had not changed.

"Is this the Lord?"

Hall felt that his worldview had been greatly impacted.

No wonder being someone else's knight is an honor in Boi.

How long has it been, five minutes? Ten minutes?

Lynn's incredible abilities are even more incredible.

An idea popped into Hall's mind.

Find the Holy Grail and resurrect King Arthur so that he can become a knight too.

Hale was taken aback by his thoughts, after all, even the Knights of the Round Table couldn't find the Holy Grail.

He's just a commoner-level magician, and he's probably far from the Knight of the Round Table.

"Ruoruo~ Master, you are so amazing!"

Xiao Ruoruo's eyes flashed with a little light, the master was really smart.

She felt like her understanding of blisters had taken another step forward.

"Well, this sister, do you want to go and sit in the church?"

It was only then that Hall remembered that he had to take care of the guests for his father.

Is it really okay to talk to Sister Lin's lord like this?
