I do research in ancient times

Ning little fox was clamoring for small calculations in his heart, but his pair of clear eyes blinked with innocent light waves, showing unlimited enthusiasm and candor.

Such a young man is so pure and harmless that people cannot take precautions, and he has forgotten that he is already the lord of the city at a young age.

The expressions of the guards softened quickly, and Lu Yong wanted to touch Xiao Juzi's soft hair, thinking that this child was more cute and cute than his younger sister.

Only Feng Kai is as immovable as a mountain.

He raised his eyes slightly, and his sharp gaze swept across the crowd.Lu Yong, who was on the verge of moving just now, immediately straightened his body and returned to a wooden state with his eyes on his nose, nose, nose, and heart.

Grass!How could I forget!The eldest son is still in front of him!

I almost got a fine when I went back!

After admonishing his subordinates, Feng Kai turned his gaze back to Ning Fei.

He thought for a while, then bent down and touched the dry road, as if hesitating.

Ning Fei was not in a hurry, and waved Zhang Erzhu to continue working, while she stood aside and continued to accompany her.

He could see that this Mu Ye brother was tempted, but he was still not sure about the nature of the cement, so he was still testing.

But his product quality is excellent, and it is a new product that fills the gap in technology. There is no competitor of the same type in the market. Consumers still just need it. What is he afraid of?

It's a pity that the steel bars can't be made for the time being, otherwise the house will be poured in one piece with concrete, and the speed of infrastructure construction will be much faster.

By the way, what kind of craft is the steel bar?

How to calculate dosage and intensity?

The earliest reinforced concrete came from the accidental discovery of a French gardener. At that time, Joseph Mohay used iron wire, so he could also try it.

However, looking at the steel knife made by the blacksmith workshop, the strength of smelting steel is still not enough. Mu Donglai must give the coke that Mu Donglai has been thinking about, but the existing method of frying steel is still not enough, so he has to find a way to improve it.

Ning Fei was wandering, when suddenly he heard the man beside him speak.

"Feidi, if I want to buy this kind of cement from Mozong, how much silver taels will I need to spend?"

"Silver taels?"

The young Juzi raised his head slightly and looked at the other party blankly.

It is said that this young lord is only three or four years older than him, but he is already a head taller than him, and the gap is likely to continue to widen.

Well-nourished modern people don't grow ducks so fast, saw lemons.

"Brother Mu Ye saved my life in the rebellion, and now I just want some cement to go back, how can I collect money?"

As he spoke, Ning Fei yelled at Zhang Erzhu who was not far away.

"Er Zhu, go and ask how much cement the fire kiln has burnt out today, find some bags and pack them, and bring them to my brother Mu Ye!"

——If there is only a small amount, Uncle Ning, who is Mo Zong's son-in-law, will give him a favor as a repayment for his kindness!

Feng Kai shook his head, smiled lightly and rejected Ning Fei's offer.

"You're welcome, Brother Fei. The noble sect needs manpower and materials to burn the cement. These must be costly. Our brothers will settle accounts clearly, and we can't let the younger brother suffer for the elder brother."

——It is impossible to use a little cement to offset the life-saving grace.

"I don't know if Brother Fei can tell you how to use the cement, and Brother Rong can buy some samples. When I return to Yongxi Pass to report to my father, the Feng family may be able to do a big business with Mo Zong."

——Mo Zong has changed too much, so don't mention the strategy of picking up leaks before, and you must observe carefully.

——A powerful partner is always more worthy of respect.

The two looked at each other, and laughed at the same time, adding to the fear of each other in their hearts.

However, since both parties have the intention to promote this cooperation, they did not show their sharpness too much in the early contact, and even showed their respective sincerity appropriately.

Ning Fei explained to Feng Kai how to use the cement in detail, and packed ten loads for Feng Kai to take away.

Feng Kai thanked him again and again, promised to visit Wupu again in ten days, and gave Mozong twenty sheep as a thank you gift.

Regardless of whether the business is successful or not, Mo Zong can finally see some meat, Ning Fei said that brother Mu Ye is very good, and warmly entertained Mr. Feng to taste Wubao's special salted boiled potatoes.

The guests and the host enjoyed themselves, and Feng Kai also expressed his interest in potatoes, but it was still too early for the potatoes to be planted, and the military rations at Yongxiguan were still abundant, so he just asked a few words and didn't mention it again.

After the meal, Feng Kai said goodbye, and returned to Ding'an City with a small cart of cement.

When he returned, it was just as the sun was setting in the west. From a distance, the tower of Yongxiguan was tall and majestic, the walls were high and the moats were deep, no wonder Hu Qi was intimidated.

But when you go to the city, the beauty of distance disappears, and everything is not so good.

Although Yongxi Pass is the most important pass in the north, the city wall and arrow stacks were built by the previous dynasty. Even if the Feng family took over the repairs from generation to generation, the walls are already mottled.

Not to mention the intentional ostracism of the emperor and the family, since he started his career, every generation of emperors has used and guarded against the Feng family, and has never paid the military in a timely and sufficient amount.

Then there was Queen Mother Li's chaos.

The Li family has controlled the government for more than ten years, and a large amount of money and food has gone into the pockets of the Li family members and in-laws, and less than one out of ten has been sent to the border.

If it weren't for the hard work of guarding the Northland, and no one could replace the Feng family, the minions of the Li family would have taken their place long ago.

Now that Emperor Longcheng has suddenly collapsed, the court is in great chaos, the family and the feudal lords are all planning for the throne.

Even though he knew that Hu Qi was on the sidelines and the military situation was urgent, the supplies that were supposed to be sent still couldn't be seen, it was obvious that they were making the Feng family bleed and contribute.

Carry it yourself.

Not only that, but in the sword workshop controlled by the family, the cost of weapons is rising steadily, and the best steel is only supplied to the family, and outsiders are hard to find.

It sounds good to believe in the capabilities of the border guards, but it sounds bad to block supplies and prepare for self-protection in troubled times!

Under such circumstances, knowing that the construction of fortifications is beneficial to the city's defense, he can only secure weapons, food and grass first, and put everything else aside.

"My lord, why do I feel that our wall looks so broken!"

Walking down the city, Lu Yong reached out and touched the wall, and couldn't help complaining.

"Mo Zong is so poor, but the walls of his house are smooth and smooth, which looks more elegant than ours."

"Otherwise, let's wipe it with this mud!"

Feng Kai didn't speak.

In fact, it might be that he has no ideas in his mind, but he has to test it himself to know what the cement is like.

If it was as miraculous as Mo Zong's little juzi said, it would be a big deal, and it was worth dealing with that little fox cub.

When Chief Protector Feng received the news, Feng Kai had someone pull the wooden cart to the martial arts arena.He heard that his son came back with a cart of mud, and immediately ran to watch curiously.Unexpectedly, his nephew and nephew were even more gossipy than him. When Feng Dadu arrived, there was already a circle of people around the martial arts field, each staring inside.

Seeing that the chief guard was coming, everyone flashed a passage and gave him a best viewing position.

In the field, Lu Yong was directing several craftsmen to build the wall.

The stone bricks used to build the wall are not freshly fired, but old objects picked up from an abandoned arrow stack somewhere in the old city. many.

Now these waste bricks are being piled up one by one by skillful craftsmen, glued together with unknown mud, and then coated with a thick layer on the outside, which looks smooth.

Most guards looked at it for a long time but didn't understand.

His son has a calm personality since he was young, and he likes to study and practice martial arts. He is different from ordinary brats who only know how to run wild and have fun.

Why do people grow up with a childlike innocence and start to like playing with mud? !

He had heard that there was an emperor in the previous dynasty who liked to be a bricklayer, so he finished building walls in the palace when he had nothing to do, and even built himself a small palace of gold and green splendor with his own hands.

But the repair of the palace was completed, and the world was lost. In order to warn future generations, the Taizu of the Ye Dynasty made the small palace a toilet.

His son, wouldn't he go to Mo Zong and be infected by those fools?

Thinking of this, Chief Protector Feng became a little anxious.

He looked around in the martial arts arena, and finally found his eldest son, Yushu Linfeng, who is heroic and extraordinary.

"Son, what did you get back from Niubei Mountain? What's the use of building something that can be kicked down?!"

Everyone, Mr. Feng Xiaolang, also wanted to ask the question about Chief Protector Feng, but due to the majesty of the boss, no one dared to touch this bad luck.Feng Kang had been scratching his head and ears for a long time, and when his father asked his elder brother, he suddenly regained his energy.

"Yes brother, what did Mo Zong do?"

"A good group of people don't make iron or weapons, so what's the point of playing with mud every day!"

He still remembered the history of blood and tears being taught by his elder brother last time, and he also hid behind his father's back when he spoke.

But who was Feng Kai, his eyes locked on his younger brother's position instantly, and he shrank his neck in fright, not daring to make a sound.

"father."

Feng Kai stood up and patted the dust on his body.

"I'm about to report to you that this is the newly fired cement made by Mo Zong. It can bond masonry and gravel. After adding water, it can be made into a paste that can be air-dried overnight. It is said that it is as hard as iron after drying."

Ok? !

Most of the guards raised their thick eyebrows.

Water-melting, quick-drying, firm texture.

Although the eldest son didn't explain it thoroughly, the guardian still keenly figured out the benefits of this thing.

If this thing is really useful, it will not take much time and manpower to renovate the checkpoints, fortresses, forts, and even the city walls in Yongxi. It will be an important line of defense against Hu Qi!

Seeing that his father seemed to have figured it out, Feng Kai nodded.

"not only."

He said calmly.

"If Mo Zong didn't brag, I would push Wubao a little further to the grassland, bit by bit the sphere of influence of Hu Qi, and suppress their living space."

"it is good!"

Most of the guards clapped their hands.

"Whatever you want, dad will support you!"

He didn't have much confidence in the group of idiots outside the pass, but his son never joked about business. He should have known that his son couldn't just play in the mud!

If this mud really has such a magical effect, their defensive pressure this winter will be greatly reduced, and even if Hu Qi makes a comeback next year, they will be more confident!

"When will there be results? Tomorrow?"

Thinking of this, Da Duhu was a little anxious.

"Otherwise, find someone to roast it with fire? It's dry anyway, why not dry it?!"

Feng Kai shook his head.

"That's not necessary."

He thought of Mo Zong's little Juzi's big eyes blinking innocently, and the corners of his lips curved slightly unconsciously.

"It was originally for testing performance, and it is impossible for us to repair the wall in the future."

"It's tomorrow..."

The man's gaze turned slightly, and finally fixed on a certain place behind his father.

"Tomorrow, to test the strength of the cement, someone has to keep hacking... why don't you let Ah Kang do it."

Hearing that he was called, Feng Kang instinctively straightened his body, and countless thoughts flashed through his mind.

He is not afraid of smashing the wall, he has so much strength, he can swing a big knife like a wind, and Hu Qi's cart can be chopped down so much!

But his elder brother just laughed!

Brother laughed! !

Feng Kang shivered, suddenly an ominous premonition surged in his heart.

The eldest brother laughed, don't you... you are plotting against him!
