"Your Majesty has left the palace?"
After receiving the news from his subordinate officials, Li Si stood up in shock.
The ministers present looked at each other in confusion.
The Eastern Tour is about to begin. Logically speaking, the First Emperor will not leave the palace easily.
But the First Emperor suddenly left the palace. Something must have happened, or something major happened, which forced him to leave the palace.
However, since the Qin State unified the six kingdoms, it seems that no major event has made the First Emperor, who remained calm despite the collapse of Mount Tai, so anxious.
"Li Tingwei!"
Suddenly, Zheng Guo, who was sitting on the right side of the desk, stood up and said, "I want to go to see Your Majesty!"
"Um?"
Everyone was stunned for a moment and looked at Zheng Guo with doubts on their faces.
Li Si frowned: "Does Lao Ling know what happened?"
"Does Li Tingwei not know? What is Young Master Hao doing during this time?"
Zheng Guo stroked his beard, looked around at everyone, and then looked at Li Si with a smile.
Li Si thought for a moment, then suddenly thought of something and slapped the table: "I'm going with Lao Ling, you guys are here to handle official business!"
"???"
Everyone watched the two people leave with questions on their heads.
.......
the other side.
When the craftsmen heard Zhao Hao announcing that the cement test was successful, they were all immersed in the joy of cheering.
After all, everyone has put in sweat during this period of hard work.
It can be said that it is not easy for cement to achieve today's success.
Zhao Hao's eyes were originally double eyelids, but ended up being single and double. The other craftsmen naturally worked harder than Zhao Hao.
Although Zhao Hao also contributed, he spent most of his time directing and experimenting, while the craftsmen had to constantly match raw materials, open and fire kilns.
During the whole process, everyone was tortured.
At this time, we can see the benefits of Zhao Hao's improved treatment for the craftsmen.
If it was before.
Although Qin's laws are strict, the craftsmen have long been full of complaints and dissatisfaction due to Zhao Hao's troubles.
Maybe they would even scold 'Bao Qin' behind his back for being inhumane.
After all, the craftsmen used to bring their own dry food to work, and there was no profit, just sacrifice.
However, Zhao Hao not only gave them new year gifts, but also solved their food problem.
This made the craftsmen grateful to Zhao Hao and worked more carefully.
The mentality of the craftsmen is also very simple.
What are you afraid of when you are tired?
After eating a meal, I feel strong again!
Anyway, the food you eat is not yours, you just put in some effort, that’s what you should do!
Just so simple and kind.
Just as Zhao Hao and Zhang Cang were explaining and recording the accurate ratio, a high-pitched and loud voice suddenly came.
"Your Majesty has arrived——!"
Zhao Gao and the First Emperor walked into the cement workshop, saw Zhao Hao's figure from a distance, and shouted loudly.
"Um?"
Zhao Hao and Zhang Cang looked at each other, turned their heads, and saw the First Emperor's guard of honor.
Without any hesitation, Zhao Hao, Zhang Cang and a group of craftsmen rushed towards the First Emperor.
"My son, I pay my respects to my father!"
"I will pay my respects to Your Majesty!"
"no."
The First Emperor got off the carriage directly and walked to Zhao Hao.
Zhao Hao tilted his head and asked in a low voice: "Father, what do you mean when you come here?"
"I heard that the cement has been fired, so I came to see what is called turning sand into rock!"
Ying Zheng said straightforwardly.
“What turns sand into rock?”
Zhao Hao looked confused and looked at Zhang Cang subconsciously.
You are so good at blowing it!
Why don’t you talk about turning stone into gold?
Am I a warlock?
Zhao Hao was speechless and said hurriedly: "Father, you have misunderstood, please come here!"
With that said, he took the First Emperor and walked towards the testing site.
"Father, look, this is cement."
Zhao Hao reached out and grabbed a handful of cement and handed it to Ying Zheng to see.
Ying Zheng squinted his eyes and looked at it for a while, and couldn't help but frown. It seemed to be different from what he imagined.
What kind of cement is this? It doesn’t look like it can turn sand into rock!
Seeing that Ying Zheng was silent and silent, Zhao Hao smiled, raised his finger and pointed at the concrete test block, and introduced: "Father, this is the concrete that solidifies after mixing cement and sand. Uh, this thing is really strong." like a rock;
If you insist on saying that cement can turn sand into rock, that's fine. However, Erchen feels that it is still concrete, a new type of building material! "
"Um."
The First Emperor nodded slightly.
He is the kind of boss who only asks about performance and not about working hours, so Zhao Hao will not say such superfluous words as "Do you know how difficult it is to make this thing?"
The First Emperor leaned down, put his hand on the concrete test block, rubbed it repeatedly, and pressed it hard.
The touch was slightly cold and very hard, with a smell that I had never smelled before, but it was basically the same as stone.
"Is this thing really made of cement and sand?"
The First Emperor stood up, clapped his hands, and confirmed with Zhao Hao again.
Zhao Hao put the cement in his hand back, clapped his hands, nodded and said: "It is indeed true!"
"How?"
"It's easy!"
Zhao Hao explained in detail; "Just mix cement and sand according to a certain proportion, add water and mix evenly, then put it into a special mold, wait for it to solidify completely, and then remove the mold!"
"Does this mold have any shape requirements?"
The First Emperor grasped the key point as soon as he heard it.
Zhao Hao shook his head: "Not at the moment."
"Zhao Gao!"
Ying Zheng shouted, and Zhao Gao, who was accompanying him, immediately responded: "I'm here, old slave!"
"Take two people and try it."
"promise."
Zhao Gao promised and immediately waved his hand behind him.
It is said that what the ears hear is false and what the eyes see is true.
Even though his own son had already tinkered with many good things, the First Emperor was still very pragmatic. He had to see concrete formed and tested with his own eyes before he believed that it was of great use.
soon.
Zhao Gao led two people, and under the guidance of the craftsmen, they mixed the concrete with "clang, bang, clang," and "kuacha kuacha."
Then put it into the mold and wait for it to solidify.
Then, he picked up the hammer and started beating on the solidified concrete test block.
After about half an hour, the concrete in the mold began to gradually solidify. Zhao Gao and others also smashed some sand and gravel out of the concrete outside the mold.
The First Emperor's eyes lit up.
Zhao Hao rolled his eyes in his heart.
They say they are uneducated, which is terrible.
Concrete is inherently known for its ability to withstand compression.
What is stress tolerance?
It’s just a tough front!
If you hit it with a hammer, you may be able to make a dent in the iron plate, but if you hit the concrete, it is impossible to break it.
Because of mechanical stress, the moment you hit the concrete with a hammer, the force is dispersed, and the hammer's effectiveness will naturally be reduced.
If you want to smash a piece of concrete, it is actually very simple. You only need to prop up the concrete and let it bear the force at one point to ensure that it will break into pieces with one smash.
This is because concrete resists compression, not tension.
Therefore, steel bars are added to the concrete of high-rise buildings to increase its tensile strength.
Concrete with reinforced steel will not be easily smashed even if you prop it up.
It is obviously wrong for Zhao Gao to lead people to act so recklessly.
Sure enough, after smashing it dozens or hundreds of times, Zhao Gao and others were panting, but the concrete test block suffered very little loss.
"alright."
Ying Zheng raised his hand to stop Zhao Gao and others.
It wasn't that he knew that Zhao Gao and others were acting recklessly, but that the result was in front of him and there was no need to try again.
"What do you think, Father?"
Zhao Hao blinked.
Ying Zheng carefully inspected the smashed concrete test block and found that the damage was very small. He couldn't help laughing and said: "Hahaha, not bad! It's a good thing. My son is really the lucky star of Great Qin!"
"Thank you, father, brother, the emperor and the others..."
Since the First Emperor has realized the effectiveness of concrete, it is no problem to build the Zhaoyang Palace in three months. Zhao Hao will definitely release Young Master Gao and the others in advance.
However, the First Emperor did not answer Zhao Hao's words, but turned to look behind him: "What do you think, Old Ling?"
"Um?"
Zhao Hao was slightly startled, and then he realized that Li Si and Zheng Guo were coming.
"Your Majesty, at first I was doubtful about this cement. But now that I have seen it with my own eyes, I have to admire the young master's talent. Our Daqin project will add a magical object..."
As Zheng Guo spoke, he couldn't help but be filled with emotion and burst into tears.
I don't know what words to use to describe his current mood.
I have been working on projects all my life and have seen many joys and sorrows. The reason is naturally that Qin's projects are too difficult to do.
First of all, Qin's projects cannot have "tofu dregs", otherwise they will be defeated.
Secondly, countless manpower was invested in high-standard projects, and there were also many casualties.
Finally, the materials and craftsmanship must be strictly adhered to the same standards, with no deviations.
This created the legend that the Great Wall will never fall down.
According to Zheng Guo's idea, with this cement concrete, Qin Guo's projects will be easier than before, and there is no need to worry about quality degradation and endangering lives.
The slave laborers will also have more protection.
But when the First Emperor heard what he said, he frowned: "It's true that it is a sacred object, but how can the output of this cement keep up with the progress of our Daqin project?"
Upon hearing this, Zhao Hao waved his hands with a smile and said: "Father, you don't have to worry about production. As long as you master the process of firing cement, we can open a kiln and fire it on the spot..."
"Oh? What about the process of firing cement?"
"Father, don't think about it, I never do business at a loss!"
"Four or six points?" Ying Zheng raised his eyebrows.
Zhao Hao refused directly: "No!"
What a joke!
Now that the Great Qin court is asking for something from me, are you still playing tricks with me? You really think I am a child!
This is not a medical clinic, a business license is required!
Seeing that he was rejected by Zhao Hao in public, Ying Zheng's face suddenly darkened.
"What? Father is going to rob me tomorrow?"
Zhao Hao narrowed his eyes slightly and looked at the First Emperor without any sign of weakness.
The surroundings suddenly fell into silence.
This Young Master Hao is really tough!
How dare he follow the First Emperor's example of "there are no fathers and sons in the shopping mall"?
Are you really not afraid that the First Emperor will kill his son to become a tyrant? !
"call....."
"call....."
Everyone's palms were sweating and they didn't dare to take a breath.
Just as the atmosphere became increasingly tense, Ying Zheng suddenly spoke quietly: "I heard that some time ago, someone here shouted long live in front of you..."
Damn it!
Can't you afford it? !
Such a dog? !
Zhao Hao's eyelids twitched and he looked at Ying Zheng in astonishment, as if he couldn't believe that the majestic First Emperor would do such an ungrateful thing.
