Han Fei's biggest reliance is cement, if the cement can't be fired in time, all preparations are in vain. He arranged all the affairs of the imperial mausoleum construction site, and then rushed to the kiln factory where the cement was fired.

"Sir—"

As soon as Han Fei got out of the car, he saw Liu Ru is greeting him, and couldn't help but say: "If so, the matter is arranged, just let the steward be in charge, why did you come over in person?" ”

"The concubine understands that this cement is very important to the master, but come and see, my heart is not steady!"

"Well, what's the current progress of cement firing?"

"The craftsmen have burned a furnace of cement in accordance with the regulations drawn up by the master, and I don't know if it meets the requirements, the craftsmen are experimenting!"

"Very good, it's a lot faster than I expected, let's go over and have a look!"

Liu Ru walked a few steps and said, "Master, what is the use of this cement?" ”

Han Fei smiled slightly, and said: "Cement is a very magical building material, it is initially in powder form, once it is mixed with water, it will solidify quickly, it is as solid as a rock, it can be used to build cities, build bridges and pave roads, build water conservancy, build houses, etc., it is very versatile, it can be said that all civil engineering construction projects can be used, and the buildings built are very strong." ”

"So many wonderful uses for this cement? The lord is preparing to use cement to build the wall of the imperial tomb? ”

"Yes, with this cement, the walls of the Imperial Tomb will never collapse!"

"That's good!" Liu Ru breathed a sigh of relief and said, "The princess and Sister Lan are very worried when they learn that the lord asked for the order to build the imperial mausoleum!" ”

"What are you worried about? When have I ever done something unprepared? I'm sure I'll be able to fire the cement before I take over the errand of the Imperial Tomb! ”

"Well, sir, this cement is so good, and it's a profitable business......"

"Don't think about this, cement is very useful to the national economy and people's livelihood, it is a strategic resource, I have promised the emperor that it will be managed by the imperial court."

Although Liu Ru felt sorry, Han Fei had already decided, so she stopped talking.

Han Fei walked near the kiln factory, and obviously felt the cement dust in the air, so he walked around to the test site behind.

"If so, this cement ash is very much, inhaling into the body is not good for the body, don't come in the future, don't come if you don't have to, go back and let the textile workshop make a batch of masks and hoods, and send them to the craftsmen, so that they must wear them when they go to work, so as not to get sick."

"The concubine knows!"

On the test site, the craftsmen were mixing the freshly fired cement with yellow sand, and Han Fei hurried over to check the fineness of the cement. Judging from the color, it is consistent with the description in the super system, but unfortunately there is no detection instrument in this era, so it can only be verified by local methods and results.

"This cement is in good condition, each of them has a wall, and I'll see the results tomorrow!"

Han Fei instructed the craftsmen to say a few words, and then returned to the Han Mansion with Liu Ru.

The next morning, Han Fei and Liu Ru rushed to the test site behind the cement kiln factory. Han Fei personally tested the hardness of each wall by hand, and saw that most of the wall cement had solidified, of course, it had to be completely solidified, and it would not be possible in a few days, so he didn't have so much time to wait.

"Bring me a hammer!"

Han Fei personally smashed the wall with a hammer, took the cement with the best solidification as the final standard, and instructed the craftsmen to produce it with all their might.

After waiting for a few more days, Han Fei saw that a certain amount of fired cement had accumulated, so he personally escorted the cement to the imperial mausoleum construction site, and then instructed the craftsmen to pour the imperial mausoleum wall.

How had those craftsmen ever seen cement and the unbelievable way of building? But Han Fei was the general manager, so they had to obey the order, according to Professor Han Fei's method, mixing concrete, making formwork, binding steel bars, and pouring the wall.

As time passed, after the solid walls took shape, the craftsmen went crazy, and they worshipped Han Fei like a god. If they hadn't been poured with their own witness, they would have thought it was a miracle.

The strength of the number of people is large, the distance of 300 zhang, the pouring time is not long, it will be done in ten days, if it is not for the supply of cement, the time will be even shorter. Next, it was to wait for it to solidify completely, and Han Fei instructed the craftsmen to sprinkle water every day to prevent it from drying out.

He himself went back and forth, and wherever he felt that there was a problem, he had to strengthen it in time. After all, it was the first time to use cement, and he had no experience to speak of.

"Lord Han, this cement is really a treasure, it was completed so quickly, it's a miracle! However, can this concrete wall really be comparable to a stone? A steward said.

Han Fei said with a smile: "I'm afraid that there are many people in the DPRK and China who have this question, so let's order someone to build two walls on the open space over there, and pour them with traditional methods and cement respectively, and then verify it in public!" ”

"Obedience! Master Han, when will this wall be completely solidified? ”

"From the official's point of view, it's basically the same, in order to be on the safe side, in five days, the official will go to the emperor to report the victory. In the past few days, you have all inspected carefully, found suspicious things, and solved them in time, and the emperor may come to review them in person. ”

"Humble duty understands!"

The construction of the imperial mausoleum has gone through twists and turns, and the credit for the successful completion of this time will not be small, and the officials of all sizes are not only happy, but also grateful to Han Fei. They all understood that this credit was given by Han Fei.

After five days, Han Fei rushed back to the capital and entered the palace to meet the emperor.

"Qi Qi Sheng, the imperial tomb has been successfully completed, please send someone to inspect it!"

"It's only been completed in two months?" The emperor was overjoyed and said: "Han Aiqing really lived up to my expectations, and I decided to inspect it in person!" ”

The emperor insisted on inspecting the imperial tomb, but fortunately, the distance was not much, and the ministers no longer objected.

The walls of the imperial mausoleum have repeatedly collapsed, and rumors have spread everywhere, and the ministers of the court and the central government are also talking about the change of color of the imperial mausoleum, and they have avoided the errands of the imperial mausoleum. Now, the imperial mausoleum has been completed, and Han Fei has once again created a miracle, and in just two months, he has completed an errand that cost countless money and food, and no one dares to take over. This is tantamount to a heavy slap in the face of the person who doubted Han Fei's ability at the beginning.

But the ministers were always puzzled about this matter and didn't understand how Han Fei did it.

The emperor and the civil and military ministers of the Manchu Dynasty rushed to the imperial tomb and were immediately shocked by the majestic building in front of them. The emperor couldn't help but walk to the majestic wall, stroked the gray-white wall, and asked Han Fei: "Han Aiqing, is this the cement poured?" How much time did it take for this wall? ”

"Your Majesty, the entire wall, including the support columns below, is poured with cement, because the cement was too late to be supplied, it took ten days to pour it successfully, and it took another half a month to completely solidify and form!"

The ministers exclaimed, and a wall of 300 zhang was built in ten days? What kind of cement is that...... It's amazing!

Ruan Changfeng, the first assistant of the cabinet, glanced at Han Fei with complicated eyes, and said to the emperor: "Your Majesty, the construction speed of this cement is fast, if it is not strong, it will not work!" ”

This is also the question of everyone, including the emperor, if this cement wall is not strong, it will be useless no matter how fast.

Han Fei said calmly: "Your Majesty, my lords, Weichen has ordered someone to build two walls in the open space over there, the same size, one wall is a traditional masonry structure, and the other wall is made of cement, which lord can go and check the masonry wall, and then verify the firmness of the two walls!" ”

The emperor ordered to find several experienced craftsmen to test the firmness of the masonry wall, and then ordered the guards to hit the two walls with siege cones, the masonry wall collapsed after being hit five times, and the cement wall was hit ten times, and there was still no obvious damage, only some small pieces were peeled off at the point of impact, and a few fine cracks appeared on the wall.
