The matter of cement has long been no secret in Zhuangzi, and when Zhang Yi and Feng Zhidai rushed to the earthen kiln, it had already been illuminated by torches. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Sir, let's... It's finally a success! Immediately, a potter ran to Zhang Yi, pointed to a concrete block next to him that had been knocked out by the hammer with several white marks, and said excitedly: "Look, I can knock off a large piece of the big bluestone in the mountain with an eight-pound hammer, but our cement pier is only a little broken!" ”

With the vision of later generations, Zhang Yi just glanced at it and knew that the current cement pier must have succeeded, although it was only the most primitive cement, but it was definitely a major breakthrough!

It is conceivable that once this sharp weapon is used in the city defense, the defense of the Tang City will definitely immediately rub up several steps, and the courtyard can also be built into a real century-old house, what swimming pool, sauna or something as long as it can be repaired all of them, there is nothing to let the painting beat his legs, pinch his shoulders.... And then.. Then lie in the sun and count the money.

It's just that there is a problem in this, should such a big thing as cement be poked out?

"Isn't it just a stone, so excited to use it?" Feng Zhidai looked at a group of people with smiles on their faces like hillbillies, and then said to Zhang Yi disdainfully.

As soon as the words came out, a large number of eyes rolled over.

For this kind of person who does not learn and has no skills, Zhang Yi has no interest at all, and immediately asked Lao Zhong to reward all the potters with five yuan each, and the happy crowd is even more excited.

Five guan money is definitely not a small amount, a cow is only eight guan, just do it for a month to earn most of the cow, no matter who will be very satisfied.

"If your father saw you say that, would you believe it or not, he would have hung you from a tree and beaten you? And it's still a horsewhip! When the commotion dispersed, Zhang Yi said to Feng Zhidai with a calm face: "It is not an exaggeration to say that this thing is the most important weapon of the country, with it our city walls will be extremely strong, and with it we can build a road that will hardly be destroyed and go straight to any place!"

A person's vision determines his height, but you actually compare such a thing like an artifact to a stone! The sage once said, knowing is knowing is not knowing, when you have not yet understood a novelty, do not easily judge with conventional eyes, then your judgment will make you no different from those dealers! ”

Seeing Zhang Yi become serious, Feng Zhidai immediately became serious.

The long-term relationship made him know very clearly that it was impossible for Zhang Yi to joke about the matter, and once he became serious, it showed that this matter was very important.

"Please also ask Brother Zhang to teach me!" Feng Zhidai immediately bowed deeply and asked for advice sincerely.

Zhang Yi sighed, found the remaining cement used by the kiln next to the kiln and said to Feng Zhidai: "Look, it's these powders, don't look at it inconspicuous, but it can be mixed with river sand and gravel to mix thick, and it can be used to build any building, and when it dries for a certain period of time, it will be the concrete you just saw."

You don't have to doubt its sturdiness, it is definitely dozens of times stronger than things like green bricks and stone slabs, and if you use it to build a city, as long as the number of troops does not exceed a certain number, this city is a city that can never be breached! ”

When Zhang Yi finished speaking, Feng Zhidai fell silent.

It's not that he doesn't believe Zhang Yi, but this message is really difficult for him to accept, even if he sees it with his own eyes.

A city that can never be broken is almost everyone's ultimate dream!

Because once it appears, it represents living and working in peace and contentment, and it represents eternal prosperity and prosperity! Once you have such an alien iron horse, there is no possibility of attacking!

But will such a city really appear?

The cement finally did not continue to be made, but Zhang Yi did not seem to break the current stable life, and stirring himself into the muddy water of the court was not something he wanted to see, so when enough cement was fired for his own use, the kiln was dismantled, and only a paper formula was left by Zhang Yi.

Of course, the Zhang family immediately had more than a dozen artisan households who sold themselves into slavery, so Zhangjiazhuang fell into the boom of building the Viscount's Mansion again.

Since the use of cement, the construction speed of the Viscount's Mansion has increased a lot, and an artifact called Kang has also been handed down, which has become a unique secret of Zhangjiazhuang.

More people is easy to do, regardless of the cost and labor on the premise of the twenty-eighth day of the lunar month, the construction of the Viscount's Mansion was completed.

The old lady rushed to Zhangjiazhuang early in the morning with a large group of servants and maids.

Although Zhang Yi has repeatedly said that the newly built house is too heavy for residents to live in, it must wait for two months until the moisture dissipates. But the old lady stubbornly believes that if the New Year can't be spent in a home that really belongs to her, then it is not a New Year.

What's more, the ancestors of the Zhang family also have to worship, and it would be better if they could set up an ancestral hall at home, because the ancestral hall of the Zhang family had already been razed to the ground with that disaster.

"Good grandson, our Zhang family is finally thriving in your hands now, grandma is happy in her heart!" After visiting the new house, the old lady couldn't stop looking at the painting's stomach, until the painting her cheeks were red, she couldn't stop sighing, and pulled Zhang Yi to complain: "Now the family's business is several times larger than when your father was here, and there are a lot more servants or something, so it stands to reason that grandma should be blind even if she dies." ”

"Grandma, you want to live a long life, let's not say sad words!" Zhang Yi hurriedly comforted: "Sun Er met Sun Simiao Sun Daochang some time ago, it is said that his medical skills are the most powerful person in our Tang Dynasty, Sun Er plans to ask him to show you tomorrow, with him out of your body and bones will definitely be fine!" ”

The old lady didn't buy it at all, and couldn't help but fall down when she saw Zhang Yi's tears, and said while wiping her tears: "I'm just a hard-working person, people are all in groups of great-grandchildren at my age, just me.... Ay! If I die, where will I have the face to meet the ancestors of the Zhang family! ”

I can't say that!

It can be seen that the old lady is now thinking that her great-grandson is about to fall into the devil, and two days ago, she asked Lao Zhong to say that the daughter of a large family in Jingyang is good to give birth to, so that he has time to take a look.....

"Grandma, don't worry! It is said that a husband should have great ambitions," Zhang Yi hurriedly explained......

"Ambitious, your father had great ambitions back then! What happened later? Woooooo ~~~ Grandson, you just listen to grandma, even if you don't marry a wife, let's take a few concubines, you can rest assured that grandma will definitely pick a few beautiful ones for you, and make sure you are satisfied! ......”
