I do research in ancient times

Clay didn't know what Ning Fei had discovered, but he was glad that he could help his little brother, which gave him a sense of security that he was needed

.

Of course, it would be even better if you can get rid of the oil bottle uncle, and it’s okay if you can’t get rid of him, as long as he performs well enough, little brother Jizi will definitely keep him by his side.

Thinking of this, the child's pace became more and more flexible. He deliberately chose a difficult road, wishing to show his most vigorous and strongest side, and blast that middle-aged bald man!

But in fact, the middle-aged bald man was not left behind, but his little brother Jizi was out of breath and almost vomited blood from exhaustion.

Is this child a monkey? ?There are so many rocks on the mountain, he can go up in three or two steps, and he is not afraid of falling off the cliff!

Also, has it been this way before?Why does it feel like it's not so steep or detoured? Didn't Clay go the wrong way? ?

Ning Zazi, who didn't know that he was tricked by the child, blocked his self-esteem, and hurried on the road desperately, stumbling and finally not being left behind.

During this period, he repeatedly refused the helping hand extended by the bald uncle.joke!As a young man in his prime, if he can't make it this far, then what face does he have to call himself a man!

As we walked further into the mountains, the air gradually became humid, and the sound of gurgling water came from my ears.

"Is there a creek here?"

Ning Fei shouted to the two people above her head.

"I heard the sound of water. Is there a stream in Niubei Mountain?"

"Oh, that's Yangjiaowa."

Xu Jin stopped in his tracks, "Yangjiaowa is not really a river, it's just the salt water flowing from the mountain in a winding way, it's bitter and astringent and undrinkable."

saltwater?Bitter and astringent?

Ning Fei's eyes lit up.

This kind of description is generally related to salinity.Most of the bitter water flowing out of the mountains has underground springs, soaking the saline-alkali soil layer, so the water tastes bitter.

Before, he was still worried that the soil where Populus heterophyllum grows does not contain salinity, but now he is completely relieved, as long as he can find those trees, he can sit and harvest white Suda!

Thinking of this, Ning Zazi's whole body was filled with chicken blood, his waist was neither sore nor his legs hurt, and he climbed up a big rock with his hands and feet.

Clay was not far away from him, and when he saw him coming up, he pointed to the left direction.

"Brother Jizi, the cave is right there!"

Ning Fei looked in the direction of his finger, and quickly found the place where the wild boars were kept.

On the sloping land below the cave, there is a faint yellow branch and leaf, which is exactly the poplar forest that Ning Fei was looking for!

"Don't move, I found it!"

He jumped twice excitedly, feeling that the rock under his feet was not stable, and immediately stretched out his hand to grab the rock wall on one side, and carefully looked around.

It is indeed Populus heterophyllum. Its area is not too small, and it grows on the edge of Yangjiaowa.

Sitting on the Niubei mountain and backed by the grassland, there are actually many ways to get soda ash, but none of them is more labor-saving than picking it directly from the tree!

Moreover, the purity of Populus heterophylla is relatively high, which saves him the trouble of organizing people to dig stones and then purify them.

"Ah, isn't this the bitter noodle tree?"

Xu Jin scratched his head.

"You said it earlier, I'm looking for someone to transport a Huiwubao, why bother Juzi to walk such a long way, my face is pale from exhaustion."

Ning Fei felt that he had misunderstood the color.

He didn't want to discuss about physical strength, so he pointed to those Yiye Yang and asked Xu Jin.

"You said it was a bitter flour tree? You know?"

"of course."

Xu Jin rubbed his hands, a blushing flush appeared on his dark face.

"My mother-in-law...is a handyman in the kitchen. They will steam some tributes to the ancestors during the Chinese New Year in the kitchen. They use the powder grown from this bitter noodle tree. I have tasted a little bit."

Oh, just say it, then why are you ashamed?

Steaming tribute to a wicked saint, no, he is not worthy.

Only to hear Xu Jin continue talking.

"Don't dare to let Juzi know that you can't use new ones for this powder, you have to let it sit for a while before you can use it."

"My mother-in-law's steamed buns are big and soft, and they are so delicious."

Well, long-term exposure of soda ash to the air can absorb moisture and carbon dioxide in the air to produce sodium bicarbonate, which is baking soda that can be used in food processing.

Baking soda can also make calcium carbonate, all the same.

"I want the bitter noodles you're talking about."

Ning Fei touched her nose.

"You know the best place, let's go and have a look."

"Good!"

Xu Jin responded happily.

"Jizi, you said earlier that you need a bitter face tree. I know a shortcut, and there is no need to climb so far!"

He complained as he walked downhill.

"The little hairy child is just not reliable. It's tiring to go around in such a big circle! It's obvious that it's just crossing Rangziling from the back mountain. It doesn't take much time for the mother-in-law to go back and forth. I feel that we are going around in circles on the mountain. Woolen cloth!"

Little fur kid Clay almost exploded in anger.

The bald man is the most annoying!If he hadn't insisted on following with shamelessness, he wouldn't have taken brother Juzi around, he would have arrived long ago, okay?

Obviously he was the one who disrupted the situation, but now he still wants to beat him up, it's really pissing me off!

With Xu Jin leading the way, the speed of finding the tree was much faster.

This piece of Hutong (Pulus heterophyllum) forest is not small, and it spreads along the Yangjiaowa like a mountain. It is hard to say that it can be used for large-scale industrial production, but it is definitely enough for daily use.

Ning Fei collected some freshly precipitated white crystals from tree branches, and thought there should be no problem.

He filled the small wooden box he brought with him, and called Clay and Xu Jin back to the city.

"Huh? Let's go now?"

Xu Jin scratched the back of his hairless head.

"Why do you want this? I'm digging more for Juzi."

Ning Fei originally wanted to make some experimental products, but he was moved after hearing the words.

They're all here anyway, so there's nothing wrong with bringing extra soda ash and baking soda.This thing is the basic material of many experiments, and it can be used wherever it is not guaranteed.

What's more, it's not easy to come this way, his legs are sore and sore, he might be dead at night.

But... there is no container...

Seeing Ning Fei's hesitation, Xu Jin smiled lightly, then raised a thick thigh, took off the animal leather boots, and took off a cloth bag from his feet.

For a moment, a strange smell permeates the air. The first aroma is a bit like the smell of rotten leeks mixed with salted fish and roasted durian, and then it turns into sour and salty fermented soybean water, which is extremely easy to drink.

Ning Fei was dazzled for a while, staggered a few steps and almost fell, but it was the kid Klei who had quick eyesight and quick hands, grabbed his arm, and managed to maintain his balance.

But Clay's situation is no better than his little brother saw.The child was so hot that his eyes watered, his mouth and nose were squeezed together, and his face was flushed.

He signaled his little brother to run away quickly with teary eyes, but both of them were shaking their legs and feet so weak at the moment, it was already pretty good to be able to barely stand up straight, and there was no room for thinking about anything else.

Wipe... This is the legendary human biochemical weapon!How could it be so stinky!

Fortunately, there was wind in the mountains, and the smell of hot eyes was quickly diluted by the mountain wind.The air with the smell of sand poured into his lungs, Ning Juzi was like a sunfish in water, he took a few breaths desperately before he felt himself come back alive.

He looked at Xu Jin and asked with difficulty:

"Xu... Brother Xu, you..."

"hey-hey."

Xu Jin rubbed the back of his head in embarrassment.

"I forgot to say, my feet stink."

He made a gesture and wanted to raise his leg again, scaring Ning Fei and the children to take three steps backwards.

"No, just stand there, don't move!"

"Oh."

Xu Jin responded nonchalantly.

"Those of us who work in blacksmith workshops have to deal with stoves and iron blocks every day. We can't wear ordinary straw sandals. We need these animal skin boots to insulate them from fire and heat."

"But this thing is not breathable. After a long time, my feet smell bad, so my mother-in-law made me a pair of cloth socks. Otherwise, my feet will be sweating all the time, and I will be soaked in sweat at the end of the day. The soles of my feet will still be wet." Blisters, pain and itching."

"It would be much better to have these cloth socks, so everyone in our blacksmith shop has a pair. Just now I was afraid that there would be nothing to put them in, so I thought of my sock tube. This thing grows to the calf, and it can hold a lot of miles!"

No, no, no need to be so enthusiastic!

Ning Fei looked at the khaki-colored half-wet and half-dry cloth tube that smelled like roasted salted fish and durian, and there were countless rejections in commercial fonts flashing all over his body.

"that……"

He instinctively wanted to refuse immediately, but when the words came to his lips, he found it difficult to speak.

Speaking of which, Xu Jin was also kind.

How can he be so particular about a rough guy, a pair of socks is a great equipment, so he is happy to give Amway to others.

Yao thought that when he first came to Mozong, Mr. Xie had to take off the coat he was wearing and keep it properly. It can be seen that poverty is the root of all evil.

Because of poverty, as long as it can be used, it doesn't matter whether it is worn on the feet or sent into the mouth, isn't it all the same? !

Thinking of this, he felt more and more that he couldn't let Brother Xu show his sincerity.

"Brother Xu is like this," Ning Fei turned countless circles in his mind, and finally found a reason that he thought was more reasonable.

"The white soda ash I want should be stored in a container that prevents moisture and air. Soda ash can easily react in the air and turn into something else, which is the bitter noodle you mentioned."

"The ingredients of bitter noodles and soda ash are different, and there are also differences in properties, which may affect the final product."

"It's like..."

He thought about it, and decided to find an example that was easier for Xu Jin to understand.

"It's like pouring ore powder into it when you fry steel, and the impurities inside will react with oxygen at high temperature and become another substance, reducing the carbon content to the composition range of steel..."

Before he finished speaking, Xu Jin who suddenly rushed over grabbed his arm.

Xu Jin was still holding a sock tube in his hand. The biochemical poisonous gas that had just been blown away by the mountain wind struck again, and it was a super-close-up frontal encounter. Ning Fei's body shook, and his eyes turned black.

No!Brother, I was wrong!

The smelly sock bag is also great, so you can pack as much as you want!

The kid Clay rushed forward, with tears in his eyes, pushing Xu Jin's arm firmly against the poison gas.The only thought in his mind was to save little brother Saw from the hands of the big poisonous demon, but Xu Jin was born in iron, his arms were like steel pillars, how could he move!

"Juzi!"

Xu Jin's eyes were red, his nose was blowing heavily, and he stammered.

"What did you just say? What fried steel? What kind of steel? How to fry steel?!"
