I do research in ancient times

As soon as these words came out, everyone who was immersed in astonishment was stunned.

Yu Lao was the first to recover, guessing that Juzi was going to test the adhesion of the mortar, and hurriedly yelled at Zhang Erzhu to move the bricks.

Ning Fei shoveled some cement out of the fire kiln and asked Xu Baoshan to mix it with water according to the proportion yesterday. Because this time it was purely for bonding purposes, so no gravel and slag were mixed. After Zhang Erzhu brought the bricks, Ning Fei So I started trying to build a wall.

He had watched the wall-building video before, and he thought the work was not difficult.But it wasn't until I did it myself that I realized that I thought it was simple.There are dirt roads in front of the brick kiln, and it is difficult to find the level line because of the unevenness. He can also smooth the ups and downs when he plasters the cement.

"Cough cough."

Yu Lao coughed twice.

"Juzi, let us do it."

Ning Fei rubbed his nose, smiled awkwardly, gave up struggling, and handed him the trowel in his hand.

Yushan reached out his hand to stir the mud pile, sniffed the smell, and then began to build the wall with quick hands and feet.

Seeing this scene, Tang Renlong also put down the steel knife, and started to beat the master with the tool.Both of them were used to doing civil work, and they quickly figured out the properties of cement. With each layer of bricks and mud, the wall was built at a speed visible to the naked eye.

"It doesn't have to be too high."

Ning Fei suddenly said.

"After building it, find a fire to dry it, and it will be done after it dries completely."

So everyone found torches to smoke the wall again, and after the brick wall was completely dry,

After a section of the knee-high low wall had been built and dried with fire, Ning Fei picked up the refined steel knife that was put aside, and tried to insert the tip of the knife into the cement joint between the bricks.

Not moving.

He was very self-aware, and handed the knife to Tang Renlong casually.

"I'm weak, come here."

Tang Renlong nodded, gripped the handle of the knife tightly, exerted a little force, and tried to push the tip of the knife into the mud crevice.He works in civil engineering and is very familiar with the properties of these mortars and mud bricks. No matter how strong the mud bricks are, there can be no gaps between bricks. Mortar can bond the wall, but it cannot be the same as mud bricks. Hardness, with his strength, it is not difficult to tear down a freshly laid brick wall.

But this time, he hit the iron plate.

Tang Renlong's face turned red, and his relaxed standing posture was replaced by a lunge that was easier to use.But no matter how hard I tried, the knife was like piercing a whole rock, and I couldn't move forward even a little bit.

"This……?"

Yu was dumbfounded.

He has worked with mortar all his life, and he has never seen such a strange scene!

He couldn't help turning his head to look at Mu Donglai.

"Old Mu, are you really a steel knife? Don't you just use it to fool people in your bragging!"

Mu Donglai laughed angrily at his words.

He rushed forward, snatched the knife from Tang Renlong's hand, and handed it directly to Mr. Yu.

"Bragging? Is there any need for me to brag about this? This is the fine steel recently produced by Tiefang! It is a little worse than ours in Baisteel, but the steel mouth is definitely better. You open it for me. Old eyes can see clearly, this is the color that can only be achieved after a long time of frying!"

Although Yushan didn't know much about fineness, he could tell that this knife was different from ordinary weapons.

But since it's really steel, how could it not be able to fit into the cracks in the mud? He had inspected the mud just now, and it was finer and stickier than ordinary mortar, obviously nothing special!

Seeing his blank face, Mu Donglai sneered.

"What's so strange, there must be nothing wrong with my knife. If I can't cut it, it's because your big apprentice is not strong enough."

"Liu Tie, go up and try."

The old man pointed to the cement pile made by Zhang Erzhu not far away.

"You don't need to insert any bricks, just cut them directly, let them see the good steel from our blacksmith workshop!"

Liu Tie responded.

He is much younger than Tang Renlong, and he has personally participated in the forging of fine steel knives, so he is very confident in his own strength and his master's skills.

He took a deep breath, raised the fine steel knife with both hands, and exerted all his strength.

Bang-!

Ning Fei felt a toothache.

It wasn't because of his bad intentions, it was because those two old men raised their bar too fast, and before he could react, Liu Tie had already raised his knife and slashed.

What kind of routine is it to chop a concrete pile with a knife? Doesn't your hand hurt? !

Of course Liu Tie's hand hurt, but his heart hurt even more!

His fine steel knife, which was carefully fried by Shimen, curled the blade the moment he cut the spur, and the blade was twisted and deformed, and his arm was almost unconscious from the shock.

But that pile only left a white mark, not even a scratch!

"My knife!"

Liu Tie let out a scream, ignoring the pain in his hand, tremblingly picked up the steel knife from the ground, almost crying out of distress!

His steel knife!His fine steel knife ah!

Mu Donglai and Xu Jin also felt distressed. They wanted to gather around to see Liu Tie's situation, but they were suddenly pushed aside by the master and apprentice Yushan who suddenly jumped out, almost falling to the ground.

The old man Yu was rushing to stumble the spurs, his eyes were shining with green light, while he circled the concrete pile, he reached out tremblingly to touch it, with an infinitely gentle expression.

"Ju...Juzi, did you really pile this up last night? Did it become so hard overnight?"

Ning Fei recalled it for a while and nodded.

"The exact time was yesterday's You hour. Zhang Erzhu made it himself. He should still remember the time."

Hearing Ning Fei mention himself, Zhang Erzhu nodded.

"Jizi said that we returned to the city at the moment of the unitary hour.

"It's so hard all night, what a big baby..."

The old man Yu was uttering bad lines while obsessively touching the concrete pillars, the scene was a little lewd and irritating to the eyes.

Ning Fei couldn't bear to look any longer, and turned to check Liu Tie's situation.

He built the wall because he didn't want Yu Lao to chop cement. He knew that the products he made himself knew that the cold weapons of the modern era were unlikely to be the opponents of cement.

As a result, the civil engineering team escaped, but the blacksmith workshop suddenly broke out. Mu Donglai really has a way of pitting his apprentices!

From Liu Tie's yelling just now, he was probably injured.

"Are you okay?"

He walked up to Liu Tie and asked with concern.

Liu Tie moved his wrist.

"Fortunately, there shouldn't be any major problems, but it's a pity for my knife."

He looked at the fine steel knife in his hand with heartache.

"The steel that was fried with great difficulty ended up being broken in an instant. What the hell are you doing, Juzi? It's so strong that it can't be cut with a knife?!"

Hearing what he said, Ning Fei scratched his head.

"It's cement. It's the stones you burned yesterday. If you mix it and add water, it will become a mixture with good plasticity and adhesion."

"I want to use it to paint the exterior walls and reinforce them and build houses, waterproof, moisture-proof and anti-corrosion. Of course, if possible, it is best to repair the roads in the city."

"Paint the exterior walls? Yes!"

Mu Donglai on the side patted his thigh.

"My fine steel knife can't cut it, and the iron knife and hammer that Hu Qi still holds in his hand, let alone the opponent of this thing!"

He turned his head suddenly, "Right, old Yutou, you build a house, what did you say?!"

Yu Lao was still circling around the cement bricks, when he heard Mu Donglai greet him, he immediately turned his head, staring at Ning Fei with a pair of green eyes.

"Juzi, is this cement difficult to fire?"

Hearing his question, Ning Fei thought about it.

"It's not difficult, but it's a bit more troublesome. It needs to be crushed and calcined, which is very labor-intensive."

With the current technical conditions, relying on water energy is undoubtedly the most convenient.

However, there is no big river outside Xiguan, so we can only rely on manual labor. If we want to achieve mass production of cement, we need to find another way.

After hearing this, Mr. Yu's expression was slightly relaxed.

His idea is very simple, Jizi can make something with eight people, so where is the labor and energy?

Now he really cares about this big baby called cement!When it is wet, it can be bonded and shaped, and when it is completely dry, it will become extremely hard, and the forming speed is very fast, it is simply a sharp weapon for strengthening the city defense!

After so many years, their Mozong finally had something to show for it!If this cement is used well, it can definitely wash away the shame of the failure of the spurs!

Thinking of this, Yu Lao looked at Ning Fei with faint admiration.

As expected of the person chosen by Ji Ziling, even if he has been an idiot for ten years, as soon as he wakes up, he will be able to present a surprising treasure immediately!

After the sage left, not all of them have achieved results, most of them are gnawing on old foundations to make improvements. The scene of opening up a new path like this can only be seen when Yue Wanfeng is in charge of Mozong !

"God bless Mozong! The saint appears!!"

The more Yu Lao thought about it, the more excited he became, he turned his head and told his disciples:

"When we go back, we will offer incense to the saint, find more tributes, and everyone will kowtow! The saint sent seven generations of juzi to save us from a desperate situation. With cement, there is hope for Mozong's revival!"

Ning Fei is so angry!

He brought the cement mix and process with him. He found someone to dig the stones up the mountain. He even did the mixing and adding water by himself. Does this have anything to do with the wicked saint? !

If it weren't for that wicked ghost to delay the progress, Mo Zong would not have only had a construction value of 5 until the Little Ice Age approached. Now that the system has been dragged down by the wicked ghost, everyone in Mozong still regards him as a good person!

Heh, even kowtow, if practicing feudal superstition can save the world, that wicked ghost Yue Wanfeng would have already completed his task and ascended, and he would have to rely on the branch line to survive until his death!

He was so angry that he had a headache and waved his hand to stop Yushan.

"I was just going to say that we are a school that relies on technology, lacking... the great sage is dying, and he is not ascending in the daytime, so we don't have to learn from those Caoguanye temples to pray to gods and worship Buddha!"

"Furthermore, the main building is made of wood. Burning incense in it can easily cause a fire. If you really want to comfort the Dharma Sage, the results of your research are more useful than anything else. This is the foundation of Mozong!"

"Don't mention the matter of burning incense in the future. I will write the cement recipe to you later. It is best to rebuild the granary before winter. The city wall also needs to be reinforced. If there is time, I hope to build a batch of houses as soon as possible. Wait a minute I will draw up the blueprints and strive to let everyone survive this winter safely."

Ning Fei's arrangement made Yu Shan nod repeatedly.

He and his two proud disciples are gearing up to make a batch of cement right now, so as to strengthen Wubao into a golden iron bucket!

Seeing that they were no longer obsessed with burning incense, Ning Fei secretly heaved a sigh of relief.

Hmph, he has to figure out a way to burn the broken wooden statue of the wicked saint to calm the bad breath in his heart!

The author has something to say: Ning Xiaofei: In my BGM, no one is allowed to burn incense and paper to wicked ghosts!
