All that echoed in Wei Shaoyu's mind at this time was: Little question mark, do you have many friends......

"Wan'er, is the electric light you are talking about the kind of electric light that needs to be plugged in?"

"Hmm. ”

Wei Shaoyu really wants to say, sister, after all, we are the first step of scientific civilization, is your step a bit too big.

But seeing Wan'er's glowing little eyes, Wei Shaoyu only felt that his heart was about to melt.

"Okay! Brother Shaoyu fully supports you! Do what you say! But Wan'er told Brother Shaoyu, why do you want to make electric lights first?"

Wan'er pursed her lips, raised her head, and pointed to the sky.

"Is Wan'er afraid of the dark?"

Unexpectedly, Wan'er shook her head.

"When it's dark, Dad can't see when he works, but if he has electric lights, Dad can work at night. ”

Wei Shaoyu only felt that a thunderbolt hit the top of his head, and he couldn't help but be petrified on the spot.

What is a pit daddy??

If Jiang Shaoyuan knew that Wan'er's purpose in making the electric light was to let her father work overtime, would Jiang Shaoyuan be angry?

However, Wei Shaoyu was indeed shocked, what Jiang Wan said did make him feel empowered.

The role of light in the dark night is naturally self-evident, although the fire is also light, but compared with the light, it is not stable enough, consumes resources, needs to be taken care of and a series of shortcomings are naturally exposed.

If there is light, then they will work much longer hours, which is crucial.

"But Wan'er, don't you have to use tungsten filament to make electric lights, and you have to generate electricity or something, in short, it's complicated, won't it be difficult?"

Wan'er took out two things from behind her.

One is two stones glued together, and the other is a small piece of bamboo.

Wei Shaoyu picked up the stones, laboriously separated them, and immediately sucked them together again.

"Magnet??"

Wei Shaoyu looked at Wan'er suspiciously.

Wan'er pointed to the magnet and said, "Electricity." ”

Then he pointed to the bamboo piece in his hand: "Lamp." ”

Wei Shaoyu felt a little confused, and he still believed that Wan'er could use it to generate electricity, but this lamp ......

"Wan'er, although Brother Shaoyu is not as smart as you, you can't fool Brother Shaoyu, isn't this a piece of bamboo, can it be used as tungsten filament?"

Wan'er chick pecked at the rice and nodded.

"This bamboo was picked up when we were passing by a bamboo forest, called Guizhu, Edison used Guizhu as a filament at the beginning, and it can burn for more than 1,000 hours. ”

Wei Shaoyu was stunned for a long time, he seemed to have really heard of this, but he was only limited to hearing about it, hearing and practicing it was not the same thing at all, and he didn't know how to operate it.

"What about electricity?"

Wan'er took out a small yellow-orange stone from behind her.

Wei Shaoyu's eyes lit up.

it!!

Gold??

Wei Shaoyu was a little incredulous, this small stone was indeed gold.

"Sister Sushan brought it to me from the river. ”

Wan'er snatched back the gold from Wei Shaoyu a little proudly.

"What's the use of that?"

Wei Shaoyu was stunned.

"Wires. ”

"Use gold as a wire......" Wei Shaoyu had a cold face, this is probably the most extravagant sentence he has ever heard, but then again, trapped on this desert island, gold or something is really something outside the body, if you can't escape, it's really meaningless.

"Well, Vasylivsky once made a powerful magnet out of thunder and lightning, and by cutting magnetic field lines, we can generate electricity, and we have a flowing river behind us, and we can use gear sets and rivers to achieve stable hydroelectric power, and with wires, we can electrify the carbonized filament, and then we can also make glass from sand, and make light bulbs......"

The more Jiang Wan spoke, the more excited she became, but Wei Shaoyu felt that she couldn't keep up.

Wei Shaoyu was very moved, but he still took Wan'er's hand and said softly:

"Wan'er, these things you said, wires, tungsten wires and whatever, are all in the shipwreck, Brother Shaoyu will go back and get ...... for you"

Jiang Wan's excited little face suddenly froze, and the person was suddenly petrified, and there were faint tears in her eyes.

By the way, she even forgot about it.

She didn't think about it, she desperately wanted to make some contribution to Wei Shaoyu and them, but after thinking about it for a long time, she forgot that these things were ready-made at all, and all her grievances were in her eyes at this time, and they were about to come out.

Wei Shaoyu poked her little face a little embarrassed.

"Silly boy, what's the matter. ”

"Brother Shaoyu is dead, why didn't you say it earlier. Jiang Wan pursed her mouth, tears swirled in her eyes, and her little hand gently patted Wei Shaoyu.

"You didn't ask......" Wei Shaoyu smiled bitterly, but seeing that Jiang Wan was lost, he still comforted:

"But even though there are these things, you still have to know how to apply them, and you still have to generate electricity, don't you count on us Wan'er?"

After saying this, Jiang Wancai pursed her lips and nodded.

Wei Shaoyu shook his head and smiled, touched Wan'er's head, Wan'er shrank her head, and her little face was red and burst into laughter.

"Okay, start your little head and think about it, Brother Shaoyu will make you a barbecue. ”

Wei Shaoyu got up as he spoke, and picked up the salt bag.

"Brother Shaoyu, don't forget to melt the salt into the water and boil it, filter it with sand and charcoal, just like filtering water, the salt in the wild has toxic substances such as lead and mercury, and you will become stupid if you eat too much." ”

Wan'er's lovely hands were propped up behind her back, and her head was completely tilted back to look at Wei Shaoyu and said.

Wei Shaoyu was stunned.

Nima, lead and mercury? Why would that be stupid?

If it weren't for Jiang Wan's reminder, Wei Shaoyu really didn't know about this kind of thing, before he only knew that sea salt should not be eaten more, it seems that the salt they ate directly before was so toxic, it was not as good as sea salt.

laughing at himself, Wei Shaoyu felt that if he didn't leave, he would be abused into a fool.

At this time, the sky had already darkened, four or five large fires were rising in the central clearing, Bai Muyun was rushing back with the hunting team, and a few people behind were talking and laughing, the owl was carrying a wild boar, and Ze was carrying a deer.

This deer is really not small.

As soon as they entered the camp, they were greeted with a burst of cheers, the clansmen immediately sang and danced around the bonfire, the women sang unknown songs around the people of the hunting party, the children ran hand in hand in the crowd to have fun, the older clansmen laughed, and Kwon so-sun pulled Bai Xiaoyue to join them in the celebration.

Everyone's face was filled with excitement and satisfaction.

Wei Shaoyu was slightly moved.

Food is their only need, and as long as they can eat enough, these primitive people have nothing else to ask for.

And in the city, we are getting more and more tired, is it because we are asking for more and more things......
