I am a primitive

Even so, the effect is surprisingly good.

Just after the process of feeding the medicine, Han Chengcheng felt sleepy.

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

The wick made of twine leaned against the bowl of the oil lamp, burning quietly. The orange flame was 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, and didn't blow it out immediately.

Looking at the burning wick with both eyes, he seemed a little dazed.

After this state lasted for a short while, an uncontrollable joy flooded my heart.

"call!"

This kind of stillness lasted for about three to forty seconds before Han Cheng exhaled the foul breath.

The flame jumped, and without any extra resistance, it went out all of a sudden.

Han Cheng groped back to the kang, got into bed, reached out to hold Bai Xuemei's hand in his hand, and hugged Bai Xuemei to his side, and his spirit became more excited.

However, this kind of excitement is different from the previous kind of irritability without any clue, but with a kind of relief and relaxation of finding a solution.

Coupled with another dose of sleeping pills given by Bai Xuemei, Han Cheng fell asleep after lying here and thinking about things for a while...

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

First, I went to the pile of pottery bowls and found some small ones, which were thinner and lighter than the rest.

Then I started to drill holes on the rim of the bowl with something, and drilled four holes in total, facing each other in a cross shape.

Four more thin leather ropes were found to pass through the four holes.

After doing this, tie the other ends of the four leather ropes to the skeleton of the Kongming Lantern.

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

Stone and Lame are extremely concerned about the Kongming Lantern.

So yesterday, when they came back from collecting the turpentine, under the guidance of Han Cheng, they boiled the turpentine in a small bowl, smeared it on the skeleton of the Kongming lantern with a piece of bamboo strips, and then put the washed away The snake skin covered it.

Today, it has been completely done, and the snake skin is extremely firm.

Han Cheng put another ball of sackcloth soaked in turpentine into the pottery bowl with holes drilled in it.

Shi Shi, whose hands were trembling with excitement, held a Kongming lantern that was a circle larger than the ones common in later generations, and straightened a few leather ropes.

Han Cheng stretched a burning stick into the pottery bowl.

The sackcloth soaked in turpentine is extremely easy to burn, and it didn't take long to touch it, and a ball of flames with green smoke was already ignited.

Because the opening under the Kongming lantern is much larger than the bowl, and the distance between the bowl and the Kongming lantern is relatively close, after the leather rope is straightened, the four ropes tied to the edge of the bowl are formed between the bowl and the bowl. An obtuse angle exceeding 140 degrees.

In this way, except for the connection of the bowl edge, the rest of the place is farther and farther away from the bowl, avoiding the top of the bowl, and is not easy to be burned by the flame.

The heat rises and the cold falls. As a person with high scores in the comprehensive and old exams, he still remembers this clearly.

As the flame continued to burn, the airflow under the Kongming Lantern began to go up due to the heat, and it was poured into the Kongming Lantern with the top sealed.

"let go."

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

Shi Shi was very worried that if he let go, the lamp that took half a day to make yesterday would fall down and be destroyed by fire.

It's just that after Shenzi said so, he also let go of his hand after hesitating for a while...

(Just now when I opened the backstage, I saw a Wanshou, and my drowsy mind instantly sobered up. Thank you book friend LE Liangren for your great rewards and the support of all book friends, thank you everyone! But adding more is temporarily disabled, and it will be released in early May To start the dissertation defense, until now I have basically been in a state of not writing much, and my heart is in a panic... I can only wait for the dark days of the past)

-------------Chapter Dividing Line---------------

The surroundings were silent, only the slight sound of the flames burning.

The witch widened his eyes and widened his mouth, revealing his gaping teeth, the stone widened his mouth, widened his eyes, and lamely widened his mouth...

Those who watched the miracle around were all stunned and unbelievable.

Of course not after the stone let go, the Kongming lantern fell and was burned directly.

The Kongming Lantern did not fall, and basically maintained its original position after the stone let go, slowly shaking at a distance of ten centimeters from the ground.

But it didn't fly either.

The pottery bowl containing the fireball stayed on the ground and moved a few times before it stopped moving.

As a result, Han Cheng basically had a prediction before there was any experiment.

It's not that he said this to cover up his embarrassment at this time, but he was really ready for the Kongming Lantern to fly.

After all, this time, to a large extent, it was to prove whether the method he thought was feasible.

The sackcloth soaked in turpentine kept burning, and when it was about to go out, a leather rope on the side was burnt.

Such a result is within Han Cheng's acceptance range.

Although the Kongming Lantern did not fly and the rope was burnt, it proved the feasibility of this road.

What needs to be done next is just to continue to improve on this basis.

The way to improve is to make the flame bowl bigger and lighter.

Larger is to hold a larger ball of burlap, ignite a larger flame, provide more energy, and at the same time keep the leather cord on the rim of the bowl away from the flame.

Lighter is to reduce the burden on the Kongming Lantern, so that it can better expand to the sky.

Making the bowl bigger and lighter might sound like an oxymoron.

Because the bowl is made of pottery, as the size increases, the weight will inevitably increase.

At this time, it is time to test the skill of Hei Wa, a master pottery maker.

Han Cheng stretched out his hand to hold the Kongming Lantern, which had become a little tilted after breaking a rope, so that it would not be burned by the fire below.

In a short period of time, it is not easy to find two snakes of this size to paste the Kongming lanterns after peeling their skins.

Looking at the few people around who all closed their mouths and tried to put on a calm expression, but their faces were a little distorted, Han Cheng couldn't help sniffling.

'These guys...'
