I do research in ancient times

Since you don't know if it's appropriate or not, then don't talk about it.

Ning Fei rolled her eyes in her heart.

Based on his many years of experience in big families, the smiling young lord in front of him is definitely an unpredictable person.

He couldn't figure out why the other party came.

Feng Kai had rescued him in Shituoling before, but at that time this man was not as enthusiastic as he is now. He looked at him with no emotion in his eyes. He just regarded saving people as a task, which has nothing to do with him. his identity.

After Ning Fei came to Mo Zong, he had also learned about the current situation with the three elders. He knew that the Daye Dynasty was a society with distinct levels, and the Feng family stationed at Yongxiguan was the real power faction, but Mo Zong had no intersection with these people.

Before, when people were starving to death, they didn’t even ask. Potatoes and cement came to the door as soon as they were born. As the saying goes, weasels give chickens New Year’s greetings, so he has to guard against them.

Pooh!Who the hell is a chicken!

When Feng Kai spoke, countless thoughts had already turned in Ning Fei's mind.

He felt that the other party was mostly for cement.After all, Yongxiguan has been farming for many years, and the Feng family doesn't seem to be short of food.

If it's cement, it doesn't matter if it's seen. Cement is always made out of it.

After the scientific research project is completed, the most important step is to convert the results into cash, and fool the rich and stupid local tyrants into buying patents.

However, the concept of patents does not exist in this era, and it is not cost-effective to buy out the production process and formula of cement at one time.

He originally planned to sell the excess cement as a sample after Mo Zong's infrastructure was completed.Now that Hu Qi and Ye Chao are facing each other at the border, it seems unlikely that there will be a major war before next spring, so there is a lot of room for cement to play.

For export, Ning Fei originally aimed at the Feng family.In his view, the Feng family is a real power faction that supports their own soldiers and self-respect. There are some lands that are left unattended, and Yongxiguan is no different from their own manor.

Be your own boss, of course you have to use the best.Cement can build fortifications, consolidate city defenses, improve transportation, and shorten the time for dispatching troops between fortresses within the customs.

Just like what they did to Mo Zong before, he had to pay a price if he wanted to, Wubao's potatoes were enough for the winter for the time being, and now he urgently needed some non-staple food to improve his nutrition.

It is the peak period of infrastructure construction recently, and salted potatoes are served for three meals in the food room.Everyone in Mozong gnawed with relish, and bluntly said that they have never tired of eating potatoes in their life, and they have a special liking for them.

But Ning Fei couldn't take it anymore.

When in his life did he live a life with only staple food? !It’s true that potatoes are a full-priced nutritious food, but eating is not only for survival, but also for the pursuit of high life!

At least it needs to be a little meaty to be considered complete.

Thinking of this, the smile on Ning Fei's face became more sincere.

"Young master, you are too polite. There is no repayment for saving your life. You have questions, but it's okay to talk about them. I will tell you everything, and I will say everything."

"Ning Juzi is a cheerful person."

Feng Kai nodded.

"I think Ning Juzi is young and promising. If Juzi doesn't think our army is vulgar, you can call me Muye."

Ning Fei was taken aback, almost unprepared for this sudden trick.

But he quickly reacted, hit the snake with the stick, and smiled sincerely:

"I haven't crowned yet, and I don't have a name. Brother Mu Ye can call me Ning Fei directly."

"Okay, Brother Fei."

The man showed six white teeth.

He pointed to a cement construction site not far away.

"Brother, outside the city, I saw that the outer wall of Wubao has been refurbished, and the city is also paving roads and building houses. The reason why the noble clan can complete so many civil works in half a month is because of the gray mud?"

"Brother Fei, what exactly is this?"

"Oh, that's cement."

Ning Fei answered very straightforwardly.

Although he is not used to the title "Feidi", he also knows that the ancients liked the friendship between elder brother and younger brother. Feng Kai is a few years older than him, and he is the future benefactor, so it is not a loss to call him elder brother.

"Cement is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can harden in air and water. If sand, stone and other materials are added, it can be firmly cemented together."

While talking, Ning Fei carefully observed Brother Muye's expression.

The first step for the gold master is to show enough professionalism and authority, and try to render the project results into a super futuristic and epoch-making magical product.It doesn't matter if you don't understand it, the more you don't understand it, the more high-tech it looks, so that the money owner can think of the potential of investing and making a fortune.

"The latest batch of cement has been tested, and the grade and quality are sufficient for construction. The concrete made of crushed stones with it is not only hardened quickly, but also has obvious strength and anti-erosion properties. We use it as the foundation of civil engineering and city defense. material."

He said it lightly, but in fact, his mind was full of coquettish tricks of attracting venture capitalists, and he hit the point that the other party cared about the most without making a sound.

Heh, I'm not afraid that Brother Muye won't take this Amway.

Sure enough, the tall and straight man gradually restrained his smile.

Feng Kai listened very carefully, following Ning Fei's beating fingers, he glanced over several construction sites of Mo Zongwu Fort one by one, and the blade flashed in Mo's eyes from time to time.

"What does Feidi mean to say, this kind of soil can build roads?"

He pondered for a while, then asked slowly.

Ning Fei nodded.

He felt that it was superfluous to explain in words, so he simply took Feng Kai and his party to the road construction site under the city wall.

At that time, Zhang Erzhu was leading people to ram the roadbed. When they saw Ning Fei approaching, everyone immediately stood up and saluted.

"Hello, Juzi."

"Juzi is here."

Ning Fei nodded, and introduced Feng Kai's purpose to Zhang Erzhu and others.Hearing that he was the young master of Yongxi Guanfeng's family, everyone in the blacksmith workshop came up to salute and thank him for his kindness in helping Juzi.

"Cough cough."

Ning Fei coughed lightly, and looked sideways at Feng Kai.

"I won't say too many polite words. Didn't Brother Mu Ye want to ask about road construction? What Zhang Erzhu and the others are repairing now is a cement and concrete side road."

"We're going to renovate the inner city's sewage system at the same time, so we've only advanced the part between the city wall and the main building. If Brother Muye is interested, you can check it out yourself."

Hearing what he said, Feng Kai was not polite, walked to the side of the concrete road that had just been plastered halfway, stretched out his hand and rubbed the face.

The newly paved concrete road has not yet solidified, and Zhang Erzhu is printing vertical and horizontal anti-slip patterns on it with a mold produced by the blacksmith workshop.

He saw a few eye-catching fingerprints suddenly appear on the well-leveled road, and he felt bad all of a sudden.

"Young master, please be merciful! Our road is not dry yet, if it is damaged, it will be broken tomorrow!"

Feng Kai was taken aback.

"What are you doing tomorrow?"

"Yes!"

Zhang Erzhu's eyes were fixed on the concrete surface, the more he looked at it, the more painful he felt, wishing he could smooth out the two marks immediately, otherwise his heart would always be burning with pain.

At last he still remembered that the young man in black was a guest of Juzi, so he said subduedly:

"Master Feng, don't look at the cement that is so watery now, it can be completely dried in one night, smoother than a pavement made of bluestone slabs!"

"The bluestone slab still needs to be quarried for materials. The road we made out of mud only needs to tamp the roadbed, and pour the mold directly on it, and it will be formed tomorrow morning! Our road is not afraid of water, so after maintenance Rain and snow are not afraid of mud, and cows and horses can walk on it safely."

"Look over there."

Zhang Erzhu stretched out his hand and pointed to a section of concrete road that had been laid not far away.

"That was laid the afternoon before yesterday, and it is ready for use."

As he spoke, he picked up the buckets used for cement, and poured two full buckets of water directly on the concrete road. Zhang Erzhu still felt that it was not enough, so he asked the disciples in the same group to pick it up.

He was jumping around arrogantly, and Ning Fei didn't intend to stop him.

There are so many road construction teams, he chose Zhang Erzhu's team on purpose.

Zhang Erzhu has a simple and honest face, and his speech is rough and straight, which is most suitable for dealing with unpredictable smart people like Feng Kai.

Sure enough, Feng Kai folded his arms, his eyes fixed on the gray road, thoughtful.

Seeing seven or eight buckets of water go down, the entire concrete floor became cleaner and cleaner, without any splash of plaster.The man in black looked at it for a while, then suddenly stretched out his foot and stepped on the road, and then spoke slowly.

"Feidi, what if we soak this road in water?"

"No problem. When the concrete road was first built, it was supposed to be watered for maintenance."

Ning Fei affirmed.

"Wubao's sewage renovation basically uses this kind of concrete, and the water resistance is no problem."

"Our outer city walls are also made of this material. The brick joints are bonded and the outer walls are coated. The strength and hardness are much better than that of concrete and mortar."

When he said this, Feng Kai seemed to have finally become interested.

"Use this mud to burn bricks?"

The man touched his chin, "It's not impossible. Mud is easy to shape, and it doesn't need to be fired. It saves labor compared with green bricks."

"Brother Mu Ye has a good eye, cement bricks are indeed a good choice."

Ning Fei was honest.

"But we haven't used it yet. Brother Muye has also seen that Mozong's manpower and material resources are limited, and we don't have the ability to knock down and rebuild the Wubao in a short time. But now the battle is tense, and Mozong can't guarantee safety even though he is in a corner. So we applied cement to the exterior wall for simple reinforcement.

"

He doesn't mind exposing his shortcomings, and sometimes showing weakness is also a strategy to win trust.

Feng Kai could come to visit so soon, maybe he has been paying attention to Mo Zong's movements, and it is impossible to be unaware of Mo Zong's embarrassment.

A person like him can't be cheated. If he is not allowed to figure out the bottom line, he can't trust him.

Sure enough, the man's eyes moved slightly, and a flash of light flashed calmly.

"That's such a pity."

"However," he changed the subject, "it's not a trivial matter to repair the outer wall. I wonder how effective the cement coating will be?"

Hey, here it comes, here it comes, the fish is hooked.

Ning Fei laughed heartily.

It's true that Mo Zong is a pauper, but the Feng family is not rich enough to rebuild the entire Yongxi Pass!

He has learned about the market, and now, except for the palace and the mansions of the big families, ordinary people use straw mud bricks and mortar.Outside the pass, there was a lot of wind and sand, and the city wall had to be repaired every once in a while. The maintenance fee was not a small sum.

Coupled with the fact that successive years of wars have consumed manpower, and there are not so many strong men serving corvee, the broken wall at Yongxiguan is not much better than Mozongwu Fort.

Can such a wall stop Hu Qi's sword and fire hammer?

Don't worry about this Mu Ye brother not being tempted!
