Chongwen Hall was no longer in class, and the children of various families who had been studying in Chongwen Hall were called to the construction site by an order from Li Chengqian.

The children of the military have been forced by their father to practice martial arts and fight hard since they can remember, in order to kill more people on the battlefield. The children of civil officials have been reading the statutes and learning the Tang laws since they can remember, because these things have to be memorized backwards no matter what officials they do.

As the eldest sons of each family, their childhood was full of hardships, but it was also a blessing. Because they just need to complete the orders of their father or grandfather, and concentrate on their studies, they don't need to know how the food is made, and why the wheelbarrow can save a lot of effort.

"They all went to the construction site to find ways to save effort. It doesn't matter if you're working, it's okay to poke and be an uncle there. As long as you get involved, the sooner the academy is built, you can enroll the day earlier. ”

With Li Chengqian's order, Changsun Chong, Qin Huaidao and others rushed into the construction site like crazy.

The reason for their madness was not the prince's order, but a piece of good news that made them feel relieved—

I heard that after the college is built, they will eat and live here, and they don't need to go home at night!

After suffering too much pressure from their families, they are still young people after all, how can they not be ecstatic when they encounter this opportunity to leave home openly.

Changsun Chong felt that the manpower was sometimes exhausted, and he simply counted on these disaster victims who were working, and he didn't know when he would go. So he didn't hesitate to send one of his guards home and ask him to bring all the inferior horses from his family's horse farm to the construction site.

Yu Chi Baolin is very direct, his generals are the same as his father, they are all strong men with tigers and bears, and just now a group of disaster victims who are still struggling with the roots of the tree were easily pulled out after they joined.

Li Ke felt that the construction site was chaotic and the people lacked management, so the efficiency would be affected, so after consulting his brother, he took over the management and began to divide the workers into groups and assign work separately.

As for Li Tai, he was worried.

Looking at the people sweating in their busyness, and then looking at their round belly, Li Tai didn't think he could stand this sin.

However, the students in the Chongwen Pavilion all jumped into the field at this time, and even Liu Renshi, who had always been cheating and cheating, was digging the soil. If he doesn't go down, it won't be like that.

Seeing Li Tai's sad face, Li Chengqian smiled slightly and patted him on the shoulder: "Qingque, since you don't want to be tired, you don't need to go down." Do you remember what my brother told you before? The labor of the wise is the same as that of the fool, and he should not be blamed. ”

Li Tai scratched his head: "What the imperial brother said naturally makes sense, but here, the younger brother really doesn't know how to exert his intelligence." ”

"Do you remember how we got the water from the pond when we were in the palace?"

Li Tai just thought about it for a while, and then looked at the craftsman who was still throwing cement on it, and suddenly his mouth suddenly opened, and he called two carpenters to make solid pulleys.

As long as there are solid pulleys, the craftsmen working on the second floor will not have to put cement in bags and throw it on. A rope can solve a lot of problems, and the speed of the project can be increased by I don't know how much.

The Ministry of Industry did not get involved in the construction of the academy this time, probably because it felt that such a thing was not enough to mobilize the power of the imperial court.

Every year, the craftsmen were requisitioned by the imperial court to do twenty days of day labor. Many projects in the Ministry of Industry are used to save money. Because there was no order from the imperial court, the craftsmen who worked in the construction academy had to be paid by the East Palace.

Regarding this article, Li Chengqian did not feel any distress. It is only natural to get money for work. What's more, since the news of the daily payment of wages was announced on the first day, the work of the craftsmen has become more elaborate. In the absence of a level, with a bowl of water, the craftsmen have managed to make the building of the academy extraordinarily flat. The cement paved ground will not be painful if you step on it barefoot.

The land had been leveled to the banks of the Weishui River, and after leaving enough safety distance, the skilled craftsmen who would be the supervisors began to build dwellings for the gentlemen of the college. The small courtyard with a vegetable field by the river is much more comfortable than the house in Chang'an.

"Hehe, although we are full of wealth, the means of accumulating wealth are far inferior to those of the prince! Now that the college has been built, we only need to bring our family's luggage and move in directly. Okay, the old man in this yard can't ask for it in vain, and the required expenses will be deducted from the old man's routine after he takes office. ”

Mr. Yang Du of Luoyang was a member of the Yang clan of the previous dynasty, but because of his long relationship and the fact that he was not appointed as an official, he was able to escape.

After the founding of the Tang Dynasty, both Li Yuan and Li Shimin invited him to go out of the mountains and enter the government many times, but all of them were refused. As a result, Lao Yang, who was about to become moldy at home, was tempted by a letter from Li Gang and immediately rushed from Luoyang to Chang'an.

"Sir, what are you saying, everyone who teaches and educates must be respected. It's just a small courtyard on the bank of the Weishui River, how dare you ask for money! ”

Yang Du laughed, stretched out his hand and patted Li Chengqian's shoulder: "Boy, you still don't have enough control over people's hearts." Haven't you heard the saying 'I'd rather die than eat the food that comes to you'? When your academy is built and great Confucians from all over the world come to teach, if you force them into the courtyard, it will be counterproductive. Only by asking them for money can they live in peace. ”

Yang Du, who visited the construction site of the college, was very satisfied. Originally, when he heard that there were still people doing big projects in the year of the catastrophe, he was surprised, for fear that the old things would be staged at the end of the Sui Dynasty. But who would have thought of this, only to find out that the so-called big project is also just a means of disaster relief.

After arranging for the guards to send Mr. Yang Du to live in Chang'an, Li Chengqian returned to his tent and continued to deal with the pile of pulleys.

When I was in high school, I studied pulley, and I still remember that I could always score more than 90 points in physics at that time. But now that I look back, I remember clearly what I remember at the beginning, but I don't know where I was squeezed into by the various convenient side roads in the city.

The fixed pulley is to change the direction of the force, and how much can the moving pulley double the force?

While reminiscing and trying, under Yan Liben's unclear gaze, Li Chengqian was able to compete with this pile of wooden pulleys.

The appearance of cement made Yan Liben admire His Royal Highness the Prince, although he couldn't understand what the prince was doing, but he still followed left and right, ready to build new wheels for the prince at any time.

The process of learning is arduous, even if it is a small impression to regain the memory.

A simple pulley set allowed Li Chengqian to spend a month on the construction site, and he didn't even return to Chang'an when his younger brother was born.

During this period, the emperor's personal eunuch Zhang Yun came once and couldn't figure out what the prince was doing, but when he saw that the prince was fine, he left.

Yu Shinan was sent over by Li Gang, and when he saw a room full of large and small wheels, he thought that Li Chengqian was playing, and he was furious. But after a few words of conversation with Li Chengqian, the old gentleman made amends in shame, and then returned to Chang'an with confidence.

The time soon came to the end of July, and the construction site on the bank of the Weishui River was still in full swing. The locusts, all but gone. The bugs, which used to be rampant throughout the pass, are now dried and crushed and piled up in the storerooms of the farms. The farm has tripled in size and is in the process of turning the locusts into eggs and meat from poultry.

Some of the people affected by the disaster had no choice but to accept the government's relief, while many more gathered at construction sites on the banks of the Weishui River, exchanging their labor for food and copper coins.

At the beginning of August, Li Chengqian finally ended his retreat and let six guards carry a huge box and two small boxes out of the tent.

The site of the college's office building was originally a large stone. In order to lay the foundation, the craftsmen led people to dig out the stone.

But who would have thought that the deeper and deeper you dig, you still can't see the whole picture of this boulder. It wasn't until I dug more than a dozen feet that the full picture of the stone was finally revealed.

There is no way to deal with it by manpower, and in desperation, the stonemasons can only use the most primitive method, burning the stone and splashing water, hoping to destroy the stone little by little.

Seeing the stones in the pit, Li Chengqian smiled slightly, and immediately ordered the workers to clean up the site.

I haven't studied mineralogy, so I don't know the type of stone, but looking at its swarthy and solid appearance, it can't be dealt with in a day or two.

"Brother Huang, you can figure it out. I heard you have a way to deal with this stone? ”

Seeing Li Chengqian, Li Tai immediately came over.

He tried to pull the stone up with a pulley, but the rope broke with the force of hundreds of people, and the stone still did not move.

"Naturally, there is a way, when you used a solid pulley to lift the stone before, the dragon gate you built is still there?"

Hearing what the imperial brother said, Li Tai immediately ordered a few carpenters to push the gantry crane over. He predicted that although the gantry crane was made of wood, it would be okay to bear the quality of the stone.

Yan Liben patted the iron box with the cow tendon rope inside, and said in surprise: "Your Highness, are you going to use this thing to lift the stone?" ”

He couldn't understand that the prince could deal with this boulder by fiddling with wood in the tent for a while, and secretly ordering the blacksmith to build some iron wheels?

Soon, Li Tai brought over the gantry crane he led the craftsmen to make. The best beef tendon rope is mixed with hemp rope, and the rope with thick arms will never break. After instructing the craftsmen to assemble the pulleys onto the gantry crane, Li Chengqian stepped aside.

The skillful craftsman had gone to the pit and put the thick rope on the stone again.

Connect well.

This time, there were no more than a few hundred people, but more than a dozen strong men pulled the rope, and in the sound of the rope being tightened, Yan Liben, who was standing on the edge of the pit, suddenly danced with his hands: "It's moving!" It's really moving! Keep it up! ”

"Hey! Hey! ”

With the sound of the trumpet, the boulder that made everyone sad during this time was really dragged up, and the appearance of the volley levitating in the air was full of courage.

There was no need for an order, the craftsmen knew what to do.

Although the gantry crane built by Li Tai is rough, it takes into account the convenient things such as "wheels", and hundreds of people push and drag, and the boulder is out of the pit along with the gantry crane.

Li Tai stood aside and watched the whole process, and saw with his own eyes that the boulder had shifted its position under the manpower, and his shocked hands were about to be stuffed into his mouth.

This....

It's just an iron box, how can a boulder that hundreds of people have no choice but to be dragged up by a dozen strong men?

The solid pulley must not have this ability, the royal brother has been stuffy in the tent for so long, what is it in the box?

At this moment, Li Tai had to mention the status of the imperial brother in his heart again.

With such an easy way to dominate such power, could it be said that the imperial brother really gained the power of God?

After everything is made, it needs to be continuously improved in order to become perfect. The same is true for the pulley group, just when everyone was happily preparing to throw this stone to the ends of the earth, the iron box on the gantry crane made a crashing sound, and more than a dozen strong men who maintained the boulder hanging in the air suddenly felt that the rope in their hands had recovered its weight, and they were dragged and fell on a big horse.

And the boulder also fell to the ground, and the ground sank.

Fortunately, there is no fear of death under the stones.

After comforting the frightened migrant workers, Yan Liben leaned in front of Li Chengqian with a sad face: "Your Highness, it seems that your god box still needs to be adjusted again, this boulder has only fallen in front of the site of the office building now, and has not completely left the scope of the academy." ”

After speaking, he also looked at the small iron box held by the two princes and the guards.

"Don't look at it, this iron box is different from the big iron box, it is not used to hang boulders. However, since the stone was out of the confines of the house, there was no need to make any effort to get it out. It just so happens that you're not a good carver, aren't you? He put half of the stone back into the earth, flattened out a flat surface on it, and carved an aphorism. After the stone is buried, wouldn't it be nice to build a small garden around the stone and plant flowers? ”

When Yan Liben heard this, he circled around the stone and imagined it, and found that after such treatment, it was really not abrupt for this stone to appear here.

"Brainless, didn't Dayu just tell us that we can't always follow the rules when considering things!"

instructed the guards to take down the broken pulley set, and Li Chengqian was ready to return to Chang'an.

History has its own stubbornness, and the old lady still added a younger brother to herself, and the name she took happened to be Li Zhi....

Retreat and cultivation, no, it's because he has been tinkering with the pulley group for so long, Li Chengqian feels that it's time to ask the bigwigs in the court to face up to the craftsmen.

Now that you've traveled to this era, you can't just go on like this. The throne or something, many people regard it as the ultimate goal, but Li Chengqian doesn't think so.

After returning to Chang'an, Li Chengqian did not go back to the East Palace directly, but came to the Ordnance Prison and directly asked the chief eunuch Ouyang Shuo for something.

The ordnance supervisor never thought that he would be visited by the prince, and Ouyang Shuo had already coveted it when he saw that he would make a windfall as a prisoner. With the best wishes and the best smile, he received His Royal Highness the Crown Prince.

However, when he heard that the prince wanted an eight-ox crossbow to play with, his beautiful smile suddenly turned bitter.

"Okay, my prince, don't you know that the Eight Ox Crossbow is a military weapon, how can you give it to each other privately? Don't say that I will get you a body, just let outsiders touch it, it can be regarded as a dereliction of duty in our weapons prison, and the whole prison is up and down, and the head of the person on the item is not guaranteed! ”

Kicking Ouyang Shuo, Li Chengqian said angrily: "When I was alone on the bank of the Weishui River to make a fake eight-bull crossbow, why didn't I see Yan Liben crying like you and calling your mother?" ”

Although Yan Liben also participated in the production of the Eight Bull Crossbows, he only took the carpenters under his command to be responsible for the production of the crossbow cart and crossbow arms, and the most confidential part of it was still top secret, and even he did not dare to investigate. Since Wang Shichong and Dou Jiande pacified, look at the generals of our Tang Dynasty, which one brought a crossbow when he went to war? We all know that the power of the Eight Bull Crossbow is great, but in ordinary battles, how can it be used? Even if it is used, it is generally used to shoot arrows and nail them to the city wall for soldiers to climb. If it is used against people, it is unconscionable! "Recommended Reading: /.. /

Li Chengqian grew his mouth ....

Weapons are too powerful to be used against people? No, although "kindness" is the traditional virtue of the Chinese nation, it is too stupid for you to use weapons with kindness when you are external!

From the time weapons are made, they are meant to be used against people, and enemies that can be killed with weapons have to be exchanged for soldiers' lives?

During the conversation, he unconsciously walked to the arsenal of the ordnance supervisor, and Ouyang Shuo leaned down on the door very barely. You can go in, but you have to split him in half.

Li Chengqian didn't want to kill this guy, the dignified prince was embarrassed by a petty official, and it was too ugly to hear it out.

Helplessly returned to the East Palace, and even sighed when he ate.

Kindness to foreign enemies is a bad problem that has been handed down since ancient times! Needless to say, it is all caused by thoughts such as "benevolence" and "kindness".

It's just that if you are kind to the enemy, the enemy may not be kind to you!

The soft is afraid of the hard, this is a divine sentence that can be enshrined as Guigao at any time.

If you want not to be bullied, be weak and kind, can it work?

Ever since he was a child, he beat up the senior thugs who went to the orphanage with his bare hands to the point of bleeding, and never dared to point a finger at the students in the orphanage again, Li Chengqian has understood a truth.

Kindness, that is, can only be given to the enemy after mastering the absolute right to speak.

Li Gang knew Li Chengqian's plan, so when he saw him sighing, he didn't come to persuade him.

If he were to make a choice, he would definitely not stand up for the craftsman. Placing artisans below the common people is not a generational practice. Li Chengqian wants to go against the unspoken rules of hundreds of thousands of years, which has the meaning of hitting a stone with an egg.

Depressed, he didn't sleep in the middle of the night, but simply stuffed himself in the house and tinkered with the pulley set, until he successfully experimented on a bow of about five stone power, and then rolled back to bed.
