In China on Earth, legend has it that lamps and lanterns appeared as early as the Yellow Emperor's time.

In addition to the oil extracted from animal fat, the other type of oil used as fuel for oil lamps is vegetable oil.

However, at that time, vegetable oil was a luxury, pressed from soybeans or sesame seeds.

Compared to that, it is now much easier to collect Nanshu oil directly from the Nan tree, just like rubber tapping.

As for using nanshu oil as an oil lamp for lighting, this was planned by Lin Luo a long time ago.

"Oil lamps, what's that?"

Hearing Lin Luo's answer, everyone still asked with puzzlement.

"A tool for lighting. ”

Lin Luo explained aloud, took out something and put it on the stone table in front of him, and said, "This is it!"

It was a dumbbell-like pottery made of clay, with a plate on the top and a seat on the bottom, connected by a pillar in the middle, and it was an oil lamp of the simplest form.

During the search for Nanshu, Lin Luo was not only making tools to collect Nanshu oil, but also researching and making lamps.

Originally, Lin Luo originally wanted to use bronze as a material to cast bronze lamps.

However, considering the number of lamps required by the tribal alliance is quite large, it will cost a lot of bronze.

Therefore, Lin Luo dispelled this idea and changed to firing pottery lamps.

After many experiments, the firing of pottery lamps is also quite smooth, and now a batch has been successfully fired.

And looking at the pottery lamp that Lin Luo took out, the bamboo witches looked up and down carefully, still puzzled.

In this regard, Lin Luo didn't explain too much, he directly took the bamboo tube next to him, and carefully poured some Nanshu oil into the upper plate.

After that, a small piece of string was pulled out and carefully placed on the plate.

This is the stem pith of a plant, which is very similar to the rush grass on the earth, and is a material specially selected by Lin Luo from the hundreds of grass stems found by the collection team to be suitable as a wick.

For this reason, Lin Luo also specially named the plant as rush grass, and at the same time changed the name of the Nanshu tree to the oil Nan tree.

Looking at Lin Luo's movements, Zhu Wu and the others did not speak, but quietly watched and waited for Lin Luo's demonstration.

After placing the wick, Lin Luo turned around and walked towards the fire pit located in the center of the council hall.

Due to the scarcity of glowstone, the tribal alliance used campfires for lighting at night.

So, at this moment, in the fire pit of the council chamber, a bonfire is also burning for lighting.

After Lin Luo walked to the bonfire, he directly bent down and picked up a burning wood from the bonfire, returned to the stone table and stretched out a small wick exposed in the tray on the oil lamp.

And under the ignition of the wood, the wick also quickly burned.

"It really burns!"

After watching the oil lamp being lit, Chief Deer suddenly said with a look of surprise on his face.

While the deer chief sighed, several other witches and chiefs also stared at the flickering lights, looking carefully.

"Smack!"

Soon, the wick made a crackling sound, causing the faint light of the oil lamp to flicker a few times.

At the same time, it also allowed the chiefs to recover from their observations.

"Lin Luo, how long can this oil lamp burn?"

Zhu Wu immediately turned his head and asked Lin Luo.

"As long as you keep adding oil and changing the wick regularly, you can keep burning. ”

Lin Luo answered Zhu Wu's inquiry while throwing the wood in his hand back into the fire pit.

"How often do you add oil?"

The fox witch on the side immediately asked.

Although the light of the oil lamp is far less than that of a bonfire, after Lin Luo lit the oil lamp, several witches suddenly discovered the advantages of the oil lamp.

Compared to burning a lot of wood, oil lamps emit significantly less smoke when burning, making them ideal for lighting in wooden houses.

Of course, the witches were still more concerned about the most important issue of the duration of the oil lamp.

"I don't know exactly when this time. ”

In response to the fox witch's inquiry, Lin Luo shook his head slightly.

Before, after bringing the Nanshu oil back, Lin Luo only tested it and determined that it could be used as lamp oil, and then came to report this matter to the witches and chiefs.

He has not personally tested the duration of the burning of nanshu oil, so it is really not very clear.

But then, Lin Luo continued: "However, the number of times you add lamp oil in one night is definitely less than the number of times you add wood. ”

Although Lin Luo didn't know how long the Nanshu oil would burn, he was still confident that it would definitely exceed the burning time of the wood.

After all, a campfire used for lighting at night should keep the wood burning vigorously at all times.

Therefore, wood must be added more frequently.

Hearing Lin Luo's answer, the faces of the witches and chiefs suddenly showed joy.

They all already knew that the process of collecting nanshu oil was much easier than cutting down trees, and even weaker women could easily do it.

If this oil lamp is really as Lin Luo said, it will undoubtedly save a lot of firewood and manpower for the tribal alliance.

After all, in order to ensure the safety of the tribal alliance at night, bonfires are burned every day in the valley mouth and league valley for lighting and guarding.

Not to mention, the smelting area is a "big consumer" of firewood, and the work of burning charcoal for smelting bronze weapons has never stopped.

To this end, the tribal alliance has also set up a special cutting team to cut down trees every day.

Fortunately, the tribal alliance will move into the cave during the dead season, so they don't have to hoard a lot of charcoal for heating.

Otherwise, I'm afraid the tribal alliance will have to invest more manpower.

So, if you can use oil lamps instead of campfires for lighting, it will definitely be a great thing for the tribal alliance.

"Chief, you send someone to keep watch over this oil lamp and see how many times you need to add oil in a night. ”

Thinking of these benefits, Bamboo Witch turned his head towards Chief Bamboo and said.

"Yes. ”

Hearing this, Chief Bamboo immediately nodded in response.

After that, the bamboo chief called a warrior to guard the oil lamp, and the others dispersed to go back to rest, waiting for tomorrow's results.

......

Following

"Lin Luo, the leader asked you to go to the council chamber!"

Early the next morning, Lin Luo, who was still asleep, heard a shout from outside the bamboo house.

"Got it. ”

Sleepy-eyed opened his eyes, and Lin Luo answered the door.

Then, turning his head to look at the side, the little one was still asleep.

At this time, Mei is not in the Menggu, but goes to the jungle to hunt and will not return until tomorrow.

Since Mei proposed that she wanted to hunt, Lin Luo told Chief Bamboo about it, and let Mei return to the hunting team as she wished.

Usually, if Lin Luo and Mei were in Menggu, then Xiaoxi would still follow them.

If none of them are there, then someone sent by the fox witch will take care of it.

For this reason, Xiaoxi cried for several days at first, but then slowly got used to it.

Lin Luo lightly got down from the bamboo bed, helped Xiao Xi cover the soft animal skin on the side, and then carefully left for the conference hall.
