After lunch, Li Yi returned to the open space outside the restaurant and started to build a naan pit.

The most traditional naan pits are rammed earth structures, made of clay mixed with wool masonry, and resemble large open-bellied water tanks with upside-down buttons.

Some places in the southern part of the Western Regions will use nitrate to make naan pit embryos, but in modern times, most of the western regions province use cheap and convenient red bricks.

Li Yilei is this new type of naan pit.

However, although it is said to be a new style, but the material is slightly different, the shape of the naan pit is no different from the traditional naan pit.

He first laid a base with red bricks, then smeared a layer of yellow mud on the bottom of the red bricks, and then used other red bricks to form a cylindrical cylinder.

The red bricks were glued together with mud, and Li Yi filled the yellow mud into the gaps in the red bricks, trying not to leave any gaps.

When they arrived at the location of the pit mouth, Li Yi came to the second bag of yellow mud that Liu Yifei and the others stepped on, divided half of it, piled it into a pile, and then took out a bag of wool sent by the errand boy from the live sheep wholesale trading market in Daxing.

"They're all here to help tear the wool."

Li Yi called the few people who were idle over and asked them to help, and they tore the sheared wool into strands together.

"Why are you tearing wool?"

Zhao Jinmai was puzzled.

Li Yi patted the mouth of the naan pit on the side and explained: "The naan is from the position of this pit, put his hand into it, and stick the naan cake on the pit wall inside.

So here will often bear the weight, naan guy will press here, or kneel here to keep balance, so here should be as strong as possible, naan pit can be used longer. ”

"And this kind of exquisiteness?"

Wu Lei tore his wool and exclaimed: "Brother Yi, do you know how to talk about cross talk?" ”

"Cross talk?"

Li Yi didn't understand what he meant.

"People say that there is a grocery store in the belly of cross talk, and they know everything."

Wu Lei smiled: "I feel like you are like this, as if you know everything." ”

“……”

Li Yi was a little speechless by his brain hole, and shook his head before joking: "I'm not a grocery store, I'm an encyclopedia." ”

So saying, he crouched down, put the torn wool into the mud, added a little salt water, and began to stir.

Soon, the wool mixed with the yellow mud and became a mud mass full of silk wool.

Zhao Jinmai also helped to stir together, and asked curiously: "Brother Yi, can this mud become strong if you put wool in it?" ”

"Of course."

Li Yi said with a smile: "This kind of animal hair and plant silk thread are very tough, and when there was not so much iron in the past, wool and cotton were used as armor.

Including modern times, there are bulletproof vests made of wool, and the effect is very good. ”

"It's awesome."

Zhao Jinmai sighed: "I feel that the wisdom of the ancients is a lot, and if you study it with modern technology, you can radiate new vitality." ”

When Wu Lei heard this, he sighed on the side: "That's right! I have always suspected that the invention of roller shoes was borrowed from the armor and horse charm used by Dai Zong, the god of the Taibao, who may have worn the world's first pair of roller skates. ”

“……”

Li Yi looked at him speechlessly: "Even if you say it's stilts, I'm a bit educated." ”

"Isn't it?"

Wu Lei was not convinced.

Li Yi sighed: "If it's really roller skates, then Dai Zong's nickname shouldn't be Shenxing Taibao." ”

"What's that?"

"God Xing Nezha!"

“……”

Liu Yifei on the side heard a black line and was speechless: "You two can really talk together!" I thought you'd say it's not that good! It turned out to be a backward work from a nickname. ”

The audience in the live broadcast room was also opened to this topic, and they posted barrage discussions.

"I think it makes sense, I've always suspected that Thunder Ling Zhen is in the past!"

"Haha! Is it okay for God to do Nezha? But I also think it's most likely on stilts. ”

"How can it be stilts? Isn't it more complete to walk unsteadily on flat ground, and climbing the mountain over the hurdles? ”

"How did this go from wool to water margin? That's too big a thinking span, isn't it? ”

The audience was discussing enthusiastically, but Wu Lei was still pestering Li Yi and asked: "Then you say, why can Dai Zong travel 800 miles a day?" ”

"That's an exaggeration, you can't take it seriously!"

Li Yi explained with a smile: "But Dai Zong has a prototype, which is an intelligence transmission system in the Song Dynasty, called urgent foot delivery.

In Shen Kuo's "Dream Creek Writings", it is recorded that he is in a hurry.

The original text is: There are gold plates in Xining in a hurry, such as the ancient feather also. With the wooden brand vermilion lacquer gold words, bright and dazzling, such as flying lightning, those who look forward to it all avoid the road, more than 500 miles a day. If there is a pre-military speed punishment, it will be issued from the imperial front, and the three provinces and the Privy Council will not be able to do it.

At that time, Song Gaozong Zhao Gou used 12 gold medals to urgently transfer Yue Fei back to Beijing, which was a holy decree delivered through a hurry.

Urgent foot delivery is a real occupation of transporting intelligence in the Song Dynasty, and it is really possible to travel more than 500 miles a day, and the fictional Dai Zongneng can travel 800 miles a day, although it is for art, a little exaggerated, but it is also understandable. ”

Hearing Li Yi say the source, Wu Lei was disappointed: "Okay, I thought the roller shoes were invented by Dai Zong!" ”

As he spoke, the wool mud had been reconciled.

Li Yi got up and covered the wool mud at the mouth of the naan pit.

Wool mud mixed with wool has a better ability to retain water than ordinary yellow mud, so with a gentle wipe with a spatula, the surface quickly becomes uniform and delicate.

However, in order to be stronger and stronger, after Li Yi finished wiping the mouth of the pit, he also used a wooden hammer to knock the yellow mud at the mouth of the pit again to make its texture tighter.

The outer layer of yellow mud is relatively simple, adding some straw residue to the remaining half of the yellow mud, and Li Yi smeared them on the outside of the naan pit.

He can only come to this job, Wu Lei and Huang Xiaoming are next to him to help him hand the yellow mud, and Liu Yifei and Zhao Jinmai are next to him to fan him, feed him water, and wipe his sweat.

Seeing this treatment, the audience in the live broadcast room was envious.

"Damn! I'm plastering at the construction site, why don't I have such a good treatment? ”

"A master with four small workers? There are still two beauties in it? Why didn't this job come to me? ”

"Brother Yi's plastering technique is not good! Replace me! As long as Mai Mai feeds me saliva, fans me, and calls me a good husband, don't get paid! ”

"Who has urine? Help me wake up that kid upstairs? ”

"I'm coming!"

"I'll come first! I'm peeing yellow! ”

With the cooperation of everyone, it only took two and a half hours for the naan pit to be built.

Jumping out of the naan pit on a ladder, Li Yi lit a piece of paper, threw it into the naan pit, and then leaned down and listened to the whirring sound of the paper burning at the vent below.

The heat from the burning of the paper causes the air in the naan pit to heat up and rise, while the cold air pours into the naan pit from the vents below due to air pressure.

This step tests the ventilation effect of the naan pit.

If the ventilation effect is good enough, the firewood in the naan pit will burn faster.

After the paper was burned, Li Yi took Wu Lei to the warehouse to find a rainproof tarpaulin, and used a ladder and a wooden frame to put it on top of the naan pit.

Seeing this, Zhao Jinmai asked curiously: "Brother Yi, isn't it faster to expose it to the sun?" ”

"Nope."

Li Yi explained: "The naan pits in the Western Regions Province can be exposed directly to the sun, because the air humidity in the Western Regions Province is already low, and the moisture in the soil will soon evaporate.

However, the air humidity in the capital is much higher than that of the Western Regions Province, and we use yellow mud, not cement, if the sun is exposed, it will make the moisture evaporation rate of the sunny side and the shady side different, and the degree of dryness and wetness is different, thus forming cracks.

It is best to let it dry in the shade, and when the degree of dryness is almost complete, then light the fire and burn it thoroughly, and the naan pit is ready to use. ”

Zhao Jinmai listened and nodded as if he didn't understand: "I didn't expect this naan pit to look so ordinary, and there are so many details." ”

"Ordinary?"

Li Yi looked back at the naan pit with a round body and a smooth and delicate surface, and felt a sense of accomplishment: "This craft, how handsome!" ”
