The sun set, the night fell, and all the hustle and bustle was suddenly annihilated by the darkness, and the tribe and the inside and outside became quiet.

That's one of the great things about primitive times.

Without the ubiquitous lighting that illuminates the night like day, the people of this era are doomed to have no way to work day and night as the later generations.

As long as you lie on the kang and sleep honestly, without saying too much about those primitive tunes, adequate sleep is still very well guaranteed.

However, among these people, Han Cheng is not included.

In the dark, he kept his eyes open, constantly thinking about how to solve the matter of Kong Ming lantern.

Stones, pottery, bones, skins, trees...... These things were considered by him many times one by one, but he reluctantly found that none of them could replace the wire.

This discovery made his head a mess and his mood became a little irritable.

After this state lasted for I don't know how long, Han Cheng became even more impatient.

Because he had decided to ignore these for now, he found that his mind was still messy and he couldn't sleep.

Insomnia has always been an extremely uncomfortable thing.

Han Cheng, who tossed and turned on the bed for a while, still couldn't sleep, and was uncomfortable, decided to give up resistance.

At this time, if you want to sleep peacefully, it is obviously impossible to rely on yourself, and you must take a dose of sleeping pills.

Otherwise, this night and tomorrow will be ruined.

After making such a decision, Han Cheng groped for the kang.

With the faint red light reflected from the mouth of the fire pit in the pit, Han Cheng picked up a grass stalk that was easy to ignite, pulled the almost sealed kang mouth a little, and poked the long grass stalk into it, against the dark fire.

After waiting for a while, a flame rose as the smoke rose.

Han Cheng drew the burning grass stalks and lit the oil lamp placed on the earthen platform.

The room suddenly became much brighter.

Han Cheng extinguished the burning grass stalks, and hurriedly sealed the burning mouth of the kang with only a small gap.

It was only a moment of effort, and the fire in the kang became a lot bigger.

It won't work like this, it won't take much time, and the kang will be so hot that there will be no way to sleep.

After doing this, Han Cheng, who was a little cold from his frozen body, hurriedly got on the kang and got into the warm quilt.

The previous preparations have been made, and now he is about to start taking sleeping pills.

After covering his hands to warm up, he reached out and touched Bai Xuemei, who was sleeping on the side, and kept shaking gently.

After Bai Xuemei let out a few quiet dreams in her sleep, she opened her sleepy eyes.

Han Cheng smiled and leaned towards Bai Xuemei.

Bai Xuemei, who was already familiar with these things, didn't even say a word, and after her two arms stood up, she fell down again and began to feed Han Cheng sleeping pills.

It's not muddy at all, and it has the refreshing style of primitive people.

This kind of sleeping pill is undoubtedly very comfortable to take, which can be seen by looking at Han Chengcheng who looked at Bai Xuemei with a cheap smile on his face.

The sleeping pills are fed for a bit long.

It wasn't over until Bai Xuemei's cheeks were a little woodened and stiff.

said that Han Cheng took sleeping pills, but in the end, it was Bai Xuemei who ate something.

Still, the results are surprisingly good.

As soon as the process of feeding the medicine ended, Han Chengcheng felt a sense of sleepiness coming over him.

Reaching out and gently pinching Bai Xuemei's face, Han Cheng endured exhaustion and got up to blow out the lamp.

The wick made of twine leaned against the edge of the oil lamp bowl, burning quietly, and the orange flames were a little shaken by the wind brought by Han Cheng.

Han Cheng, who was about to blow it out, took a big breath and held it in his chest, not blowing it out immediately.

His eyes looked at the burning wick, and he looked a little stunned.

After this state lasted for a short while, an irrepressible joy welled up in my heart.

"Whew!"

This kind of stillness lasted for about thirty or forty seconds before Han Cheng exhaled this turbid breath.

The flame flickered, and there was no extra resistance, and it was extinguished at once.

Han Cheng groped his way back to the kang, got into the quilt, reached out and held one of Bai Xuemei's hands in his hand, and hugged Bai Xuemei to his side, but his spirit became more excited.

However, this excitement is different from the previous irritability without the slightest clue, but with a sense of relief and relief to find a solution.

In addition, Bai Xuemei was fed a dose of sleeping pills, and after all Han Cheng lay here and thought about things for a while, he also fell asleep......

Early the next morning, Han Cheng got busy and began to verify the solution that he had thought of in a flash of inspiration last night.

First of all, I went to the pile of pottery bowls and found a few small bowls, and they were thinner and lighter than the rest of the bowls.

Then I started to drill holes in the rim of the bowl with something, and there were four of them, two by two, in a cross shape.

And he found four very thin leather ropes to go through the four holes.

After doing this, the other end of the four leather ropes was tied to the skeleton of the Kong Ming lantern.

The length of the four ropes is the same, so that the pottery bowl can be kept in the center under the Kong Ming lantern.

The matter of Kong Ming lanterns, stones, lameness, they are extremely concerned.

So yesterday, after collecting pine resin and coming back, under the guidance of Han Cheng, they had already boiled the pine resin in a small bowl, and after smearing it on the skeleton of Kong Ming Lantern with a piece of bamboo strip, they covered the snake skin that had been washed away.

Today, it is completely done, and the snakeskin is extremely strong.

Han Cheng put a ball of linen soaked in pine resin into the pottery bowl that had been drilled.

The stone, which made the excited hands tremble, held the Kong Ming lantern that was larger than the common one in later generations, and straightened a few leather ropes.

Han Cheng stretched a wooden stick with fire into the pottery bowl.

The linen cloth soaked in pine resin burned very easily, and it was not long before it came into contact with it that a cloud of green smoke was already ignited.

Because the opening under the Kong Ming lantern is far larger than the bowl, and the bowl is relatively close to the Kong Ming lantern, after the leather rope is straightened, the four ropes tied to the edge of the bowl form an obtuse angle of more than 140 degrees between the bowl and the bowl.

In this way, except for the connection of the edge of the bowl, the rest of the place is farther and farther away from the bowl, avoiding the right above the bowl and not easily being burned by the flame.

The heat rises, the cold falls, as a person with a high score in the Wen Zong old exam, he still remembers this very clearly.

As the flames continued to burn, the air flow under the Kong Ming lantern began to go up due to the heat, and it was poured into the Kong Ming lantern with a sealed mouth above.

"Let go."

After waiting like this for a while, Han Cheng spoke.

The stone was worried that if he let go, the lamp that had taken half a day of hard work yesterday would fall and be destroyed by fire.

It's just that Miko said so, and after a little hesitation, he let go of his hand......
