I do research in ancient times

"Then what to do?"

Zhang Erzhu looked at the spur in front of him, smashed it and asked Ning Fei.

"Juzi, should we add some more soil? Why do I feel a little thin? It will fall if you kick it!"

"Need not."

Ning Fei shook his head.

"Just leave it like this, let's see the result after it dries."

"When can it dry?"

Xu Baoshan asked.

Ning Fei looked at the sky, the climate outside Yongxi Pass was dry, windy and sandy all the year round, even in summer, the air humidity was not very high.

"Come back tomorrow morning."

Ning Fei said lightly.

"In this kind of weather, it will probably dry out in one night. The experimental product does not need to be maintained, and everyone can come to see the effect tomorrow morning."

After dismissing the crowd, Ning Fei went back to the main building alone.

When passing by the main hall, he kicked the wooden statue, and felt that the difficulty of life today was due to this former host.

The system intelligence has already entered dormancy, except for saving the rewarded cotton seeds, all other functions have been suspended.On the contrary, the countdown to the task completion time limit has been hung on the main panel, and the big red letters are particularly eye-catching, which makes people very stressed.

That bastard Yue Wanfeng!

After routinely scolding her ex before going to bed, Ning Fei fell into a deep sleep.

In the dream, he was standing on the top of Niubei Mountain outside Mozong City, with the vast desert outside Yongxi Pass under his feet.There was heavy snow falling from the sky, and the snowflakes fell on the ground, covering the scattered corpses little by little, and the blood and stumps were sprayed everywhere, leaving only the pure white of the sky and the earth.

The snow is getting bigger and bigger, and it seems that it will never stop. The trees are dead, the rivers are frozen, and the cold current has frozen life. At the border, he died in the city, but because of hunger and cold, he was no longer able to stop Hu Qi from going south.

Mountains and rivers are broken, wars are everywhere, and blood flows like rivers.

The cold weather made farming difficult, but in summer they encountered severe droughts and floods one after another, food production dropped sharply, and famine was everywhere, but the tax burden on the people continued to increase.

The peasants who had been working in the fields for a year couldn't survive, so they had to sell their children and daughters to flee famine.Countless refugees gathered like water droplets, setting off a wave of earth-shattering waves that directly engulfed the royal family of the Ye Dynasty that had lasted for a hundred years.

However, this is not the end of the disaster, but the beginning of a troubled world.

The army of refugees lost its mob, and soon collapsed because of lack of supplies, and the aristocratic family that firmly controlled the supplies became a profitable oriole.

But the aristocratic family is expert in internal fighting, but externally they can't fight the barbarians who grew up on horseback.Fighting in the era of cold weapons is completely a duel of strength. Even though the children of the aristocratic families have a thousand hearts, everything is futile in the face of the absolute disparity of power. The cavalry of the Hu tribe and the barbarians swept the whole territory.

Kill, enslave, die.

The fire of civilization is gradually dimming, and famine and plague hover over everyone's head.Seeing no hope but having to endure pain, many people began to seek spiritual sustenance, hoping that death would bring relief.

But Mo Zong had been annihilated due to hunger and disease long before the arrival of all this, and only the remnant wall of Wubao was still standing at the foot of Niubei Mountain, which became the final proof.

"Little Ice Age..."

Standing on the top of the mountain, Ning Fei murmured.

Although the system had previously warned that the Little Ice Age was coming, he still felt very shocked when he witnessed all this with his own eyes.

A certain dynasty in Huaguo also turned from prosperity to decline because of the Little Ice Age, and finally to destruction.At the same time, Western civilization was quickly resupplied due to changes in productivity, not only successfully passed the Little Ice Age, but also accumulated enough strength to take off.

The system says that Mo Zong is related to the technology line of the entire era, so if Mo Zong develops well, can all this be avoided?

After thinking about it, Ning Fei woke up.

He opened his eyes and found that the genius was dimly lit, but outside the window there were already the sounds of people working.

Mo Zong is a hard-working school, everyone will work consciously, before they could not eat enough and had no energy, but now that they have potatoes, everyone gets up early in the morning to start work.

Ning Fei sneezed, and slowly got up from the wooden bed, feeling his whole body was so sore.

Although there is nothing wrong with his body, his physical strength is really weak. He was tired after doing some work yesterday, and he felt a little groggy when he got up today.

But as the lord of a city, he can't sleep until the sun rises every day.No matter how hard or tired you are, you have to get up, and today you have to check and accept the experimental results of soil and cement.

After tidying himself up briefly, Ning Fei was ready to call the project team to work.When he walked downstairs, he remembered the tragic situation in the dream world again, so he went around to the main hall and kicked the "wicked saint" to vent his anger, and then left the main building with a yawn.

As soon as he went out, he was startled by a group of people around the door.

In addition to the eight people in the project, there are three elders and two middle-aged men whom they don't know.

"What are you all doing around here so early in the morning?"

Ning Fei was stunned.

"I heard that Juzi's mortar was burned out yesterday. Mortar is something that our civil engineering team uses every day. Yushan wants to come and see it."

He reached out and pulled a bald middle-aged man, "This is my first disciple Tang Renlong. Some time ago, he went out to reinforce the mud bricks of Yongxi Pass. He was only able to build the city yesterday. I brought him here specially today."

Oh, it turned out to be migrant workers.

Tang Renlong saluted Ning Fei, and before he could say anything, he was pushed aside by Liu Tie.

"Juzi, I brought my master and elder brother here. They didn't believe you said yesterday that the charcoal could burn for five days, and you said that Juzi was bragging. Tell them!"

"Tiezi shut up!"

Mu Donglai blushed, scolding this apprentice for the hundredth time in his heart that he had no brains.

Last night when Liu Tie came back, he rushed to his house, and told him about the charcoal that could burn for five days, and even sprayed him all over his face when he got excited.

But he doesn't believe it!

He doesn't know whether the mortar can be burned out, but there is no charcoal that can burn for five days!Absolutely impossible!

He scolded Liu Tie, but the kid didn't give up, so he squatted at the door of his house early this morning, insisting that he go to Juzi to discuss the burning of charcoal.

The kid also said that the civil engineering team lost face to the blacksmith workshop yesterday, and they must get it back!

"I did not say!"

Mu Donglai coughed hard several times.

"Juzi, don't listen to Tiezi's nonsense, how can I question Jizi's bragging, Tiezi is stupid.

Then he introduced it to Ning Fei bluntly.

"This is Xu Jin, my eldest disciple. He went to Guanli with Tang Renlong, and now he is back. I will bring him here to show Juzi."

After he finished speaking, Mr. Xie squeezed forward, lowered his voice and muttered to Ning Fei:

"I saw that they were all coming, so I followed. They are so many, I'm afraid you will suffer."

Ning Fei laughed.

Mr. Xie thought he was the idiot who needed someone to take care of him, and always wanted to take care of him.

He comforted Xie Zeng a few words, greeted Tang Renlong and Xu Jin, and then said with a smile:

"The cement that I tried yesterday should have dried out. Since everyone is here, why don't you go and have a look with me?"

Everyone responded positively to these words, so a group of people went up the back mountain and went straight to the fire kiln.

In front of the fire kiln, an abstract sculpture with a height of half a person stands proudly.

Ning Fei turned his head away, feeling that after one night, Zhang Erzhu's cement pile would be more irritating to his eyes, and it would easily lead to the yellow waste in his brain.

"Is this a tripping spur?"

Yu Lao raised his eyebrows, walked around the concrete pile in a little surprise, and reached out to touch it again.

"Is this... of stone?"

They tried the stone spurs, but they were able to withstand Hu Qi's fire attack, but it took time and effort to polish the stones and bury the piles, and there were not many stones suitable for grinding, so they finally gave up.

Zhang Erzhu said that it was made of mud yesterday. Can it be strong?

Seemingly seeing his doubts, Ning Fei smiled and pointed at the cement pile.

"You can chop with a knife."

Ning Fei was very kind and didn't mention using his feet. The cement he made himself knows that although the grade is not top-notch, it is enough for general daily use, and the strength is absolutely no problem.

The three elders and several middle-aged people are not young anymore, kicking the concrete piles can cause sprains in mild cases, and fractures in severe cases. Isn't this a scam?

It's just that no one understood his kindness. Tang Renlong, Yu Lao's first disciple, pressed the dirt pile, and then kicked it up.

thump—

Ning Fei shrank her neck, feeling pain in her heart when she heard it.

Fortunately, there was no cracking sound of bones breaking. Tang Renlong should be a practitioner, and he took a few big steps backward after being shaken. It was his junior brother Zhang Erzhu who barely stopped.

Zhang Erzhu's cement art remains unmoved.

"Use a hammer."

Yu Lao said in a deep voice.

At this time, he was no longer as relaxed as before, his eyes were solemn and serious, his hands were tightly clenched into fists, and his brows were twisted into a rope.

Seeing this scene, Ning Fei felt relieved.He knows that his soil cement is basically finished, and now he only needs to publicize the performance advantages.

The few people present are all experts, and there is nothing more interesting than letting the experts discover a bit for themselves.He just stood aside and didn't speak, completely letting Yu Lao and his party do whatever they wanted.

Hearing Yu Lao's order, Tang Renlong was stunned for a moment, then nodded, and picked up a sledgehammer from the side of the kiln.

This hammer was used to smash the slag. Tang Renlong swung it with one hand and smashed it hard at the bottom of the cement pile.

boom!

Not broken.

"Change knives."

Yu Lao looked at Mu Donglai.

"Aren't you guys thinking about fine steel recently, is there a finished product?"

"There are, but only a few."

Mu Donglai was very reluctant.

"But it took a lot of effort, it's a waste to cut this."

Yu Lao blows air through his nose, secretly scolding Mu Donglai for being stingy.

"Just take it and try it. What are you afraid of with a fine steel knife? It's so bad that it can be broken. At worst, you can sharpen it again!"

Seeing that he was angry, Mu Donglai hesitated for a moment, and finally asked Liu Tie to go back to the blacksmith workshop to get the knife.

Tang Renlong shook it in his hand, "Well, it's a good knife."

"of course!"

Liu Tie had a proud face.

"This is the treasure that our craftsman has painstakingly refined. Although it is not as good as Baisteel, it is much sharper than ordinary iron knives, and its strength and toughness are also top-notch!"

Tang Renlong nodded, and was about to raise his knife to cut down the concrete pile, when Ning Fei called out to stop him.

"Wait a minute."

The young man with a delicate face waved his hands and said softly to Zhang Erzhu who was standing aside:

"Go get some bricks, I have something I want you to see."
