Early the next morning, Pei Zhixian was the first person to wait in the courtyard, and he seemed a little anxious.

In addition, Zhang Ji also came, and Zhao Cheng made a special trip to the academy to invite him. This point is very important, she is so good, and as a Wenzong who is as famous as Li Qingzhao in this era, her influence is very special, if she recognizes it after reading it, she doesn't need to tout, and writing a factual article is a free big advertisement.

In addition, Cai Wenji called Qin Ming and Su Zaifang to come.

"Pretending to be a ghost, Zhao Cheng, what are you going to do?"

Su Zaifang knew that Zhao Cheng was a bit of an evil kid, and he could always attract countless eyeballs by this kid, so he couldn't help but bar.

Pei Zhixian looked at him impatiently and said, "No one invited you to come." ”

Su Zaifang felt a little hot at this time, but in view of his family background, he was afraid of Lao Pei, so he quibbled: "I was invited by Mr. Zhang Ji, and I happened to come over to take a look if I had nothing to do." It is about Zhao Cheng, this person has always had strange and strange things, which aroused the curiosity of students. ”

Zhang Ji also felt a little embarrassed, but it was also inconvenient to fork the road.

Lao Pei wanted to smoke this goods, but he glanced at Zhang Ji, since she was the one who called, he had to forget it. After all, pumping people is not the subject of this issue.

"Isn't it just two stones stacked together, what's so strange?"

Qin Ming, who was not well with a shoulder injury, asked directly.

Lao Pei was annoyed when he saw Qin Ming's disabled person with a shoulder injury, and he had the impression that this thing was a brainless thing, he was known as the courage of Wanfu to fight the streets in Huangbianzhai, and the person who solved the case and saved them was the scholar Zhao Cheng.

However, given that the problem mentioned by Qin Ming was also something that Lao Pei was anxious to know, he looked at Zhao Cheng curiously.

Zhao Cheng squatted down to check the solidification of the cement, and it should have been stable after this night.

Then he got up proudly, got up and said to everyone, "I didn't say how amazing this is, but I just said that it can replace ordinary slime and can be used for bonding in all kinds of buildings." It's just a trial now. ”

Su Zaifang didn't care what the purpose was, and began to chew the words, "Since it's nothing unusual, it's just a kind of slime, why do you want to make a new one?" Is it the same as your Xiaobaiwen, a thing used to cheat money? ”

"You don't know anything about power!"

Zhao Cheng's response this time was a bit of a surprise. But very helpless, although Su Zaifang is annoyed now, he can't help it, this kid not only has a mysterious and weird yang finger, but also a very orthodox literati, almost all of them are protecting him.

Qin Ming was considered to be in a group with Su Zaifang, and took a step forward and said, "Master Su, don't be angry, wait for Qin to step on a certain foot and make you angry...... Oops! ”

General Qin stepped on the stone with too much force, and the sour feeling once again made Qin Ming realize what it meant to be humiliated.

He, who is known as the courage of Wanfu, was shocked in public?

Surprisingly, this doesn't seem to be any ordinary slime at all. Qin Ming was very familiar with the stickiness of ordinary slime, so he dared to step on it vigorously. Because one of the main points of this is that when ordinary clay encounters a strong force, the two bonded stones will separate.

Since there is a process of separation, even if the force is unloaded, then the feet will not be painful, and they will not be so lazy. But it was tantamount to a mistake in judgment and too much force, but the hard rock did not move at all, and the soles of the feet suffered a heavy blow.

In addition to Qin Ming's old face being slightly red, his cognition has really been subverted? But he was still not convinced, so he changed his way, this time he slowly put his foot on the joint of the two stones, and eased and continued to exert force. But it still didn't work, and the two stones were still firmly glued together.

Hah-

Even though Qin Ming had a shoulder injury, he lifted the two large stones that were combined with one hand, and then slammed them on the ground.

Got some rubble splattered around, but still couldn't separate the two boulders?

"Try ...... again"

Qin Ming was unconvinced and tried several times, but it was still the same.

The more this happened, the more embarrassed Su Zaifang's face became. I always felt that something was wrong, but I was very helpless that Zhao Cheng was so weird, that is, he had so many magics.

"Huh......"

Zhang Ji and Lao Pei were the first to show interest in this thing, and they looked at the seams of the two stones closely, and they couldn't care about Qin Ming and Su Zaifang's embarrassment.

Cai Wenji had some bad taste, looking at Su Zaifang with a strange expression, and he didn't know why this little Su Gongzi would lose face and suffer every time, he was scolded by the traitorous father from the earliest academy forum, and because he provoked his father, it was easier for the father to bring in Zhao Cheng's ideas and pay attention to Zhao Cheng.

The incident in which he instigated Dong Jianwu's martial arts competition is the same, the incident in Huangbianzhai and the black shop in Huangbianzhai is similar, and now the cement incident is like this?

I didn't feel much when I didn't want to, and after thinking about these carefully, Cai Wenji was a little speechless, and found that Zhao Cheng was really amazing, and she also found that this Su Zaifang was too ordinary. Elsewhere, he is indeed a high-profile talent, but unfortunately it will look very mediocre when he puts this Chizhou and Zhao Cheng together.

"The effect of this cement is truly magical."

After observing for a long time, Zhang Jiyu said, "There are too many fields that can be applied, such as rivers, city walls, roads and bridges, etc. ”

Pei Zhixian simply loved this thing, twisting his beard and nodding frequently, "Incredible." With this thing, the intensity of the offensive can be greatly increased, and more importantly, the progress of the construction can be accelerated. ”

Lao Pei had the experience of being a county governor in the northwest border, so he thought of these problems.

Cai Wenji secretly glanced at Zhao Cheng and asked curiously: "Lord Zhixian, why do you say that it can speed up the progress of project construction?" ”

Zhao Cheng responded: "Taking the city wall as an example, the ordinary clay in the construction of the city wall is not enough, and it mainly relies on gravity to stabilize it, so it is required to be very wide at the bottom, and then go up in a conical shape." Since the city wall needs to be stabilized by gravity, the rock shape needs to be relatively regular, which requires a large number of stonemasons to correct and polish the rock. ”

"But we have already seen the adhesion of cement, which means that with this thing, there is no need to polish the rock a lot, and the strength can be ensured by significantly reducing the amount of stone. This equates to a lot of time and labor savings. ”

At this point, Cai Wenji became even more curious. People like her are really interested in a magical new thing, and they began to think about it according to Lao Pei Xiaozhao's words, and thought of many prospects for the future.

After all, Cai Wenji is rich and still very young, coupled with the special complex of home houses in her thinking, so Cai Xiaoniang's first thinking is: get a vote of cement to come in, and build a house that can be inherited for a hundred years and will not collapse.

And Lao Pei, the cool official, first thought of money, so he approached Zhao Cheng and said in a low voice, "If it's just that the White Agarwood Department relies on secret recipes to produce this thing, then no matter how magical it is, it won't be of much use." It can only turn the squire's tyrant Zhuangzi into a house that the official army can't break, but it will never be able to strengthen the offensive in the north of our dynasty, let alone the great cause of surpassing the Great Wall of the First Emperor, what do you think? ”

Lao Pei is really the most insightful official of this era, in a word, if the output is not large, it cannot be cheap, then it will always be just a trick in the hands of the rich, and it cannot be called industry.

In fact, in the Song Dynasty, Hanwa really has no shortage of brain inventions and secret recipes, and almost every household has its own secret recipe. There are ancestral secret recipes in Lang, and farmers have ancestral agricultural pollination hybrid techniques. Blacksmiths also have ancestral near-alloy formulas, and some have ancestral methods of refining coke, so that their forged weapons greatly surpass those of other blacksmiths.

And so on, there were too many things like this in the Song Dynasty.

The official technology is even more awesome, such as the water transport instrument, which is a complex machine with a large clock-like structure, which is really hundreds of years earlier than Europe, geometry, shipbuilding, bridges, etc., which is really an order of magnitude difference compared to other civilizations of the same era.

It's just that things that include the government will become monopolistic and exclusive recipes once they get it.

Seeing Zhao Cheng's strange look, Lao Pei understood people, and said: "This county doesn't want to win people's love, this is the secret recipe of people's white agarwood, and this county probably knows what she means, she wants to rely on this thing to make money, right?" ”

Zhao Cheng clenched his fists in a low voice and said, "Xiang Gong Ming, she should mean this." ”
