After rebirth, Bai Yueguang became a black lotus

At the same time, Shi Sinian also came to the island, but there was no one on the island. He immediately called Lin Liang and asked where they were.

The signal at sea is not very good and is intermittent.

But what can be heard is that Lin Liang asked him to wait on the island, and if there is any news, he will be informed immediately, otherwise he will go to find Lu Youzhi and him later.

But how could he be at ease waiting on the island?

After a lot of torment and entanglement, Shi Sinian called his friend in H City: "Hello...Xiao Zhu, I remember you have a private yacht in H City, right?"

"Can you drive over to Lanai now?"

"I...I have a friend who lost contact at sea. I have to go find her."

The person on the other end quickly agreed, and after hanging up the phone, Shi Sinian collapsed on the sofa.

At this moment, there was only one thought in his mind.

As long as Ahzhi is safe, he can do anything, even die.

The sun is very strong at noon.

After discussion, Lu Youzhi, Tang Yun and others decided to stay on the island temporarily and wait for rescue. The first reason was that the sea was too big and they would get lost if they were not careful. The second reason was that the boat was too small, and there were six of them in total. If they encountered waves, it would be easy to capsize, so the best way was to wait here.

Waiting for Sheng Rou and others to arrive.

Of course, we can't just wait and do nothing.

According to observations, this is an undeveloped deserted island. The humidity on the deserted island at sea is relatively high, and there must be a lot of poisonous snakes, insects, rats and ants. Large animals may also exist, such as bears, wild dogs, etc.

If it was a wild dog, it would be okay, but if it was a bear, encountering it would mean death.

"Just pick up some firewood nearby, don't go too far."

"It's going to be done."

Lu Youzhi left in a hurry and didn't bring her cell phone or any tools, so she could only use a more primitive way of making fire. She first asked Tang Yun and others to collect firewood, while she looked for tools to make fire on the beach.

With her tremendous mental power, she soon saw a beer bottle covered under the beach.

She picked up a stick and dug out the beer bottle, then smashed the entire bottle, leaving only the convex lens at the bottom, and returned to the boat with the convex lens.

Tang Yun and others were still collecting firewood. Lu Youzhi was not in a hurry. She had a hunch that Sheng Rou and others would be able to find her.

Ask her where did this premonition come from?

Perhaps, it was given to her by God. After all, before Qu Fu appeared, except for some inevitable things, everything she did was basically smooth sailing.

Tang Yunyan Shuangshuang and the others were too slow, so Lu Youzhi joined in. After a while, they picked up a large pile of firewood and piled it up as high as a small hill.

"Azhi...what should we do next?"

The girls present were all spoiled young ladies at home. They felt a little tired after doing just such a small thing. Of course, what was more important was that a lot of firewood was not all on the ground and they had to pull it up manually. There were also bugs on some trees and they were really afraid of bugs.

"Make a fire and create some smoke. Then they'll be able to see us if they pass by here."

Lu Youzhi didn't let them do anything and started to organize the firewood herself. She took out some of the harder firewood at the bottom and put it aside. She put the driest, most flammable weeds on the top and the dead branches under the weeds. Then she took out a convex lens, aimed it at the firewood pile, and lifted it up, making sure that the sunlight would be refracted onto the firewood pile through the convex lens.

Lu Youzhi's series of actions left Tang Yun and others beside her completely confused, and they couldn't help but look at each other and whisper.

"Azhi...Azhi, what are you doing?"

"Isn't it about making a fire? Why did she pull out all the firewood? Isn't the more firewood the better?"

"Why did she put those weeds on it?"

"Maybe... because it's more flammable?"

"But we don't have a lighter!"

"So we should rub wood together to make fire."

Tang Yun, Yan Shuangshuang and the others still knew the standard way of making fire by drilling wood together. They didn't understand what Lu Youzhi was doing at all. They thought she was playing because she was too tired. Yan Shuangshuang pursed her lips and said, "How about we talk to Ah Zhi? Ah Zhi should be tired too. Let's do it one by one later?"

Tang Yun nodded in agreement: "I think it's okay."

Zuo Su looked at Lu Youzhi: "Azhi, why don't you take a rest first..."

Before Zuo Su could finish her words, suddenly, a cluster of small flames sprang up from the dry grass.

The fire started, although it was small, it was real and quickly spread to the entire pile of dry grass.

Zuo Su: ...

Yan Shuangshuang: ...

Tang Yun and others: …? ? ?

I was stunned and had no idea what was going on. How did the fire start?

Several people looked confused.

Lu Youzhi had already put down the convex lens in her hand and looked towards them with a faint smile, her eyes falling on Zuo Su: "Su Su, did you call me just now?"

Zuo Su: ...

Zuo Su finally came back to her senses. She opened her mouth and stared at the burning firewood: "Ah, Ah Zhi... this, this fire..."

The others also looked at Lu Youzhi, their eyes full of disbelief.

"What's wrong? Is it too small?" Lu Youzhi said, "It doesn't matter, it will get bigger in a while."

Zuo Su and others: …

That's not what they meant!

They want to know how the fire started!!!

There is clearly only one piece of glass.

Finally, Tang Yun couldn't help but raise her doubts. Lu Youzhi laughed and said, "This is not a piece of glass."

“This is a convex lens.”

"A convex lens has the function of focusing light. After being refracted by a convex lens, sunlight will converge at a focal point. The energy of the light received at this focal point is very high. If flammable objects are placed at the focal point, they will easily ignite."

Lu Youzhi patiently explained to everyone. Her words were simple and easy to understand. Tang Yun and others finally understood what Lu Youzhi was doing just now. She was not playing, she was using a convex lens to make fire.

OMG!

"Azhi, how come you are so smart!"

"Yes, Azhi, we thought you were too tired just now."

"Azhi, you are so, you are so, I can't even describe you in words. I was just thinking about which piece of wood to use to make fire."

"Woo woo woo, Azhi, you are really the smartest person I have ever met."

All the girls looked at Lu Youzhi with undisguised surprise and admiration; their eyes were sparkling and full of passion.
