"Not a mirror?" Feng Chenglin's smile froze abruptly, and followed her gaze: "What is that?"

"A mirror is a mirror, but it's not the kind of mirror you dress to look at people..."

Ling Luoyu turned his head to look around the corner.

"This is a light mirror... a mirror specially used for lighting!"

"Light microscopy?"

Not only the wind grows into the forest, even the old shopkeeper curiously looked at the bronze mirror in his hand.

"Mr. Ling, you mean, these mirrors...will glow, just like those lights?"

"It's not shining, it's reflection!" Ling Luoyu tapped the mirror surface of the bronze mirror with his fingertips: "The big mirror on the roof above should be the one that mainly attracts light. The light passes through the refraction of the bronze mirror and deflects the light to another. On the bronze mirror, use that bronze mirror and then fold out the light until all the bronze mirrors have light fold out, then the room will be bright..."

"Really? Then let's save trouble!" Fengcheng Lin Yue was eager to try: "San Young, or, let's try?"

Ling Luoyu glanced at the surroundings, and gestured sideways: "Be careful when you open it!"

"no problem!"

With Ling Luoyu's consent, Feng Chenglin flew towards the roof and tried to push the circular mirror surface, but he couldn't help but be speechless.

"Three young masters, can't push..."

Ling Luoyu's eyes were a little strange: "Fat man...what are you doing?"

"Open this thing... Didn't you say that you want me to open it?"

Ling Luoyu looked like an idiot, making Feng Chenglin a little hairy.

"No... Third Young Master, you said..."

"Such a big thing must be controlled by the agency... Do you think people living here have to climb up if they want to open the thing?"

Fengchenglin "..."

like--

That's it!

For a moment, he crawled there in awkwardness, and whispered.

"I...then I will first look at the edge of this thing to see if it gets stuck..."

After taking a pretentious glance, he flew down and faced the old shopkeeper's smile.

"What are you laughing at?" Feng Chenglin glared uncomfortably, "I have time to laugh at me, so I don't want to look around... Maybe I will find the mechanism!"

The old shopkeeper's smile suddenly stopped, and he turned angrily to look for the so-called organ.

It's just that in such a messy situation, it's not easy to find an agency!

Feng Chenglin turned around and was very discouraged: "Three young masters, ask me to say that when I have a chance to see Dingmiao again in the future, I must look for a book about the formation of his organization...or else every time. When encountering such a thing, we are very passive!"

The old shopkeeper was rummaging for things suddenly, and he glanced at Feng Chenglin calmly before continuing with his own affairs.

Ling Luoyu stood in the middle of the hall, looking thoughtfully in the direction of the hall door.

"Fatty, go to the left side of the gate of the temple..."

She herself went to the right.

Feng Chenglin heard the sound and went over quickly: "San Shao, have you found something?"

"No!"

"In terms of the layout of this palace, it should be a place such as a conference hall. If there are institutions in such a place, it should be at the door..."

Just like the principle of decoration now, the light switch will be set in a place like the door.

Because it is simple and convenient to operate.

Feng Chenglin searched the door carefully, only as if he had remembered something, he took a step back and looked thoughtfully at the bronze mirror on the roof.
