The cement dried after a few hours.

In the past few hours, Li Qinzai yawned and went home to make up for his sleep, but the onlookers did not leave, and carefully stood from a distance to observe.

Liu Ah Si and his subordinates scattered around, wearing armor and guarding with a serious face, as if guarding a national treasure.

Such a solemn and depressing atmosphere completely aroused everyone's curiosity, and later more and more onlookers came, and the women, children and old people in the Zhuangzi came over.

They just want to know what Wu Shaolang has done, using hundreds of laborers for several days in a row, building kilns and calcining, and even stopping important ditch digging and repairing projects.

At least let us know what we've been doing these days.

Compared with the curiosity of the villagers, Li Sujie and other disciples were quite calm.

They simply consciously brought pen and paper with them, stood at a distance and recorded the steps of repairing the kiln, as well as writing down details such as the color and texture of the calcined product.

After a few difficult hours, Li Qinzai finally appeared, followed by Cui Jie and the county lord of Jinxiang.

Li Qinzai's actions in the past few days have aroused the curiosity of the whole village, including the mother-in-law and the mother-in-law's best friend.

Approaching the ditch, seeing the crowd of people nearby, Li Qinzai, who was yawning, was stunned.

What's so nice about this? Don't tell me you've been around here for hours to see when the cement is dry.

If you are really so idle, can't you find a factory to work and make screws?

Seeing Li Qinzai's arrival, the crowd of onlookers quickly gave way to a wide avenue leading to the ditch, and everyone had an unclear but awesome expression of worship on their faces.

It doesn't matter what the fifth young man has come up with, the worship will be over anyway.

With Cui Jie and Jin Xiang, dragging the two like stars on the red carpet, Li Qinzai walked to the ditch uncomfortably.

Liu Ah Si and the subordinates let go with relief.

These few hours are not a kind of torment for them, there are too many people, in case there are not long-eyed guys who have to get closer, the villagers in the big hometown, whether Liu Asi chops or not?

Squatting on the edge of the ditch, Li Qinzai stretched out his finger and poked the smeared cement, revealing a satisfied expression.

Well, it's hard and already sun-dried.

Cui Jie also poked him: "Husband, what did you create?" ”

Li Qinzai pointed to the ditch channel: "That's it." ”

"What's this gray thing on the surface? What's the use? ”

"It's called cement, as for its usefulness, it can be described as 'indestructible', no matter how roads and bridges are built in the future, it will be of great use, not only difficult to destroy for thousands of years, but also used in the military, it can be described as 'impregnable', basically no enemy can easily destroy."

Cui Jie was taken aback: "There is such a magical thing in the world?" How can it be? ”

Li Qinzai pretended to be reserved and said: "There is no such magical thing in the world, but your husband and I are full of magic, I came, and it came." ”

Turning his head to look at Liu Ah Si, Li Qin said, "Ah Si, jump into the ditch and kick it with your foot." ”

Liu Asi jumped down the ditch as he said, first looked at Li Qinzai's expression, and then carefully stretched out his foot and kicked it gently.

Li Qinzai frowned: "You haven't eaten or are you born weak?" Kick it with your best strength, and if it's broken, it won't let you pay. ”

"Wu Shaolang, the villain is really hard?"

"Hurry up, we have to mass produce it when we go back."

Liu Asi gritted his teeth, took a few steps back, ran one by one, and then flew up and kicked on the surface of the cement ditch.

There was a dull sound, and Liu Asi's huge forty-three yard footprints were left on the surface, but the ditch ...... It is still undamaged, and there is not even a single crack on the surface.

"Huh?" Liu Asi squatted down in surprise and observed, then got up unconvinced, retreated, ran away, and kicked up again.

Except for Liu Asi's footprints, there was no damage on the surface of the ditch.

The crowd of onlookers saw it in their eyes and immediately let out a cry of surprise.

Li Sujie and the other disciples had red faces, and they quickly recorded something on the paper.

Qi Bizhen couldn't help but said loudly: "Sir, your family's trilogy is too empty, disciple please live." ”

Liu Ah was angry, but the muddy goods of the Qibi family really couldn't be provoked, so he snorted angrily and retreated to the side without squeaking.

Li Qinzai waved to Qi Bizhen indifferently, and Qi Bizhen was overjoyed, excitedly separated the crowd, jumped into the ditch, followed Liu Asi's example, retreated, ran away, and kicked it hard.

The surface of the ditch remained untouched, the only difference was that the forty yards of footprints were left behind by Che Mozhen, and that was it.

"Huh? This thing is a bit weird," Qi Bizhen squatted down in surprise to observe carefully, and said: "The surface is smooth and flawless, the color is not festive, and it looks gray and depressing, but it is different from the method of pouring glutinous rice juice on our city wall, it is obviously a thin layer, why is it not broken?" ”

Qi Bizhen got up and said to Li Qinzai: "Sir, how about the disciple please use the blade?" ”

Li Qinzai nodded: "If you want to try it quickly, it's time for dinner." ”

Qi Bizhen turned to the entourage in the crowd and shouted, "Fetch my purple gold hammer!" ”

Li Qinzai sneered.

This is like a fake thunderstorm, and this heavenly cultivation is a purple gold hammer that collapses into the sky......

Suddenly, I wanted to shout and sway......

The purple gold hammer is a pair, neither purple nor gold, it is a pair of iron hammers with a rather simple shape, the so-called "purple gold", most of them are shameless to put gold on their faces.

Qi Bizhen held the purple gold hammer in her hand and weighed it for a moment, then she slammed her strength and screamed, and the hammer slammed into the surface of the ditch.

There was a loud bang.

This time the ditch was finally changed, and a crack appeared on the surface.

But Qi Bizhen froze.

He was originally a famous general, although the strength of this hammer is not as strong as his father, but it is definitely not weak, and a hammer could have opened the mountain and cracked the rocks, but he did not expect that it only caused a slight damage to the ditch with a crack in it.

Qi Bizhen instantly began to doubt life.

Li Sujie, who was watching from a distance, had his eyes lit up, and his face flushed with excitement.

He knows that the things created by Mr. will be of great use to Datang, "indestructible" and "impregnable", Mr. is really not exaggerating, isn't that the case?

Running in front of Li Qinzai in a few steps, Li Sujie said excitedly: "Sir, what is the name of this thing?" If it wasn't difficult to make......"

Li Qinzai said: "It's called 'cement', the effect is what you see, as for the manufacturing process, it's not difficult, go back and send the secret recipe to your father." ”

"Thank you, sir, Mr. is talented, and has made new contributions to the Tang Dynasty, if this thing is popularized in the world, it will benefit all the people, and it will be used in military affairs, although it is unbreakable despite all enemies, the wonder of this thing is not inferior to gunpowder and three-eyed guns."

Li Qinzai smacked his lips and said, "It's not that great, I just want to build a solid ditch." ”

Behind him, Cui Jie looked excited, but the county lord of Jinxiang was stunned.

I had heard of Li Qinzai's deeds before, and in the past year, I have heard that there is a firearm called the "Three-Eyed Gun" in the army, which is invincible in the world in close combat.

Jinxiang has always thought that it is just a rumor and a good thing.

But at this moment, she saw the advent of cement with her own eyes, and also saw its indestructible effect with her own eyes, and at this moment, she finally realized that the rumors she had heard were perhaps not exaggerated.

This person...... It's really amazing.

Trying to suppress the consternation in her heart and a hint of inexplicable adoration, Jinxiang maintained a calm expression, but the rapid heaving of her chest betrayed her true emotions.

Miaomu couldn't help but glance at Li Qinzai, and quickly retracted it.

Jin Xiang pursed his lips, his mind suddenly became very chaotic, and an irritability that came out of nowhere lingered in his mind.

Li Qinzai didn't know that Jin Xiang's heart was stormy at the moment, and he also jumped into the ditch and carefully observed the crack smashed by Qi Bizhen for a long time.

"The drying time is still a little shorter, and the proportion of river sand mixed in is also a little less, if you embed iron bars and pebbles in it, make out the concrete, and then thicken it, I am afraid that the purple gold hammer will not easily hammer ......."

Li Qinzai muttered to himself, summing up the gains and losses.

Li Sujie and Qi Bizhen on the side widened their eyes in shock.

Listening to the meaning of Mr.'s words, it seems that this has not yet reached the most powerful level of cement, and if it is adjusted again, it can be stronger, and the purple gold hammer can't be broken.

If it is used for military purposes, when the Tang Dynasty is fighting abroad, it will build a city made of cement in a key place, and no matter how the enemy cuts and chisels, it will not be damaged in the slightest.

Datang has gunpowder and three-eyed guns, and solid cement, which can be attacked and defended, isn't it really invincible in the world?

The Tang Dynasty Emperor was ambitious and vowed to make a far-reaching Taizong's exploits, which fell on gunpowder and cement.

A great event must be reported to Chang'an!

Li Sujie whispered a few words in Li Qinzai's ear, and Li Qinzai bowed silently.

After getting the permission of the gentleman, Li Sujie immediately turned around and summoned a janitarian guard, and after a few words, the janissary turned around and got on his horse and galloped, heading straight for Chang'an.
