In the chamber,

When Lin Luo arrived at the council chamber, Wu and the chief had already arrived.

On the stone table, the oil lamp that had been placed yesterday was still burning.

"How's it going? How many times did you add oil yesterday?"

Looking at the oil lamp that was still burning, Lin Luo asked out loud.

"A total of six times were added. ”

Hearing Lin Luo's inquiry, Chief Bamboo immediately replied with a happy face.

Hearing this, a smile suddenly appeared on Lin Luo's face.

Compared to Earth, the nights in this primitive world are much longer, and the oil is added six times in one night, which is much less than adding firewood.

What's more, this oil lamp is only the simplest form, if the potter is asked to improve more, expand the volume of the upper oil pan, and increase the position of the wick in the center.

Then, a hollow interlayer is made under the oil pan for water injection to cool down.

When the oil lamp is burning, the water can cool the lamp oil, reduce the volatilization of the lamp oil at high temperatures, and minimize the consumption of the lamp oil.

Oil lamps like this, known as fuel-saving lamps in ancient China, were the most ideal oil lamps in Lin Luo's heart.

It's just that it's not easy to fire such a complex fuel-saving lamp, and the potters of the Tribal Alliance have very limited pottery-making skills, and Lin Luo has asked the potters to try dozens of times before, all of which have ended in failure.

Therefore, in the end, Lin Luo had no choice but to reluctantly choose to use the simplest form to fire a batch first.

At the same time, it also allows the potter to try split firing, which can reduce the difficulty of firing a lot, and I believe it will not take long to succeed.

Thinking happily about this, Lin Luo immediately said: "The potter's side is still trying to burn an oil lamp that can save lamp oil, if it is successful, it only needs to add lamp oil three or four times to burn it overnight." ”

"Really?"

Hearing Lin Luo's words, the expressions on everyone's faces were even more pleasantly surprised.

After all, Lin Luo didn't say anything about this last night.

"Then hurry up and organize the clansmen to collect lamp oil!"

Immediately, Chief Bamboo said with some impatience.

"That's right, let's go collect it!"

The fox chief nodded in agreement as well.

He looked anxious, as if he was afraid that if he went too late, those oil nan trees would grow legs and run away.

After that, several witches and chiefs began to discuss the details of collecting lamp oil.

Because the fire beasts in the oil forest have been cleaned up, only a few warriors are responsible for protecting the safety of the team that went to collect lamp oil this time, and the rest are all women from the collection team.

In this way, the team set out in the morning and returned to the valley in the evening.

......

At night, the flickering light of the oil lamps illuminates the inside of the wooden house.

"Father, fire!"

Xiao Xi lay in front of the oil lamp, and her dimly illuminated little face was full of happy smiles.

As she spoke, she reached for the oil lamp with her small hand, as if she wanted to catch the firelight.

"Don't reach out, be careful of getting burned. ”

Seeing this, Lin Luo hurriedly spoke out to stop him.

"Hot?"

Suddenly, Xiao Xi stopped stretching out his hand, but the expression on his face was full of puzzlement.

"Yes, if you get burned near an oil lamp, it hurts. ”

Lin Luo nodded and said to the little guy.

"It hurts?"

At this moment, Xiao Xi immediately retracted his hand.

Although Xiaoxi is a girl, she is no less naughty than many boys.

Ever since he could walk, he had been running and climbing all over the valley, and he didn't know how many times he had fallen.

Therefore, she has a very deep understanding of the word pain.

After retracting his hand, Xiao Xi continued to look at the firelight with interest, and his face was full of joyful smiles.

After all, in this primitive world, night often means darkness.

At night, it is dark except for a few bonfires around the tribe for sentry lighting.

Now, with the oil lamp, it is the first time that Lin Luo's wooden house is so bright at night, which is naturally very new for the little one.

Looking at Xiao Xi, who was full of excitement, Lin Luo also smiled and turned his head to look out of the transparent stone flag window.

You can see that in the surrounding wooden houses, there are also dim lights, shining through the gaps in the wooden boards.

The oil is easy to obtain, and it can be collected continuously and regenerately, so it naturally becomes less precious.

In addition, the oil lamp in the wooden house does not burn all night, but is only used as an indoor lighting tool before going to bed.

Therefore, after the collection team brought back a large amount of Nanshu oil today, several witches and chiefs decided to allocate oil lamps and a certain quota of lamp oil to the totem warriors of the tribal alliance after discussion.

As for those ordinary clansmen, due to the limited number of the first batch of oil lamps in the simplest form that were fired, Lin Luo proposed to wait for the fuel-saving lamps to be successfully fired before popularizing them to the entire tribal alliance.

In addition, the campfires used for lighting the sentry have also been replaced with oil lamps.

Of course, those oil lamps are not small oil lamps for indoor lighting, after all, there will be wind many times outdoors, and it is easy to blow out the oil lamps.

What's more, these small oil lamps are okay for indoor lighting, but they are a little too dim when used outdoors.

Therefore, Lin Luo specially asked the smelter to cast some bronze basins like cauldrons, poured Nanshu oil into them and placed them on the chiseled columnar stone piers, making oversized oil lamps!

"I'm going to tell Wu tomorrow that I must cultivate the fire prevention awareness of the clan in advance!"

Looking at the flickering lights in the surrounding wooden houses, Lin Luo suddenly seemed to think of something, and said softly.

At any given time, a fire is a terrible disaster.

Nowadays, the tribal alliance is inhabited by all wooden houses, and if oil lamps are popularized on a large scale, the chance of fires will undoubtedly be greatly increased.

Lin Luo didn't want to make the tribal alliance have such a big security hazard for the convenience of lighting at night.

Therefore, it is absolutely necessary to cultivate the fire prevention awareness of the clan in advance, and even issue some mandatory orders to prevent the occurrence of fires to the greatest extent.

......

Busy days always go by quickly!

The busy dry season came to an end when the sweeping north wind blew off the yellow leaves and turned all the trees of the jungle bare.

On the other side of the Menggu settlement, all the clansmen, women, and children are busy packing their things and preparing to move back into the cave to spend the dead season.

"All line up, don't get crowded!"

The hunting team also stopped hunting and directed the tribesmen to enter the cave in an orderly manner.

"Gu Cao, have you packed up your things?"

Lin Luo stood in front of the door of the wooden house, raised his head and shouted upstairs.

"Alright!"

Soon, Gu Cao's answer came from the second floor of the wooden house.

"Smack!"

Immediately, a figure jumped directly from the second floor, it was Gu Cao.

After a dry hunt, the grass looked much stronger than before, and there were also a lot of scars on its body.

"It seems that we will have to build a separate wooden house for Gu Cao next year. ”

Looking at Gu Cao, who had already become a qualified fighter, Lin Luo couldn't help but think secretly in his heart.

After all, now Gu Cao has already become an adult, and he is no longer the little kid who followed him before.

"Luo, when you have a happy banquet next year, let's find a partner for Gu Cao!"

Beside Lin Luo, Mei who was holding Xiaoxi seemed to have the same idea as Lin Luo, and turned her head to Lin Luo and said.

"Hmm. ”

Hearing this, Lin Luo nodded lightly in response.

With Gu Cao's current age, it is indeed time to find a wife and start a happy life of his own. 8)
