Three whips break the father-son relationship, please call me prince

Chapter 127 Li Chunfeng is suffering

Cotton is recorded in ancient books as being called gubei, baidie, etc.

But it is not well known to the world, and its function has not been discovered and widely used.

Li Chengqian sent people to Gaochang to look for it, but in fact he was not sure whether cotton was really grown in Gaochang.

Now looking at the white cotton fluff in my hand.

His mouth was almost blossoming with smile.

There are so many things you can do with cotton.

"What is the specific situation?"

Li Chengqian is concerned about the planting area and yield.

Upon inquiry, I found out that the planting area is not too large and the yield is not very high.

He was a little disappointed, but that was understandable.

How could it be possible to plant cotton on a large scale before seeing its effects?

"Ship a batch back."

"I can be of great use."

Li Chengqian ordered.

He wanted to implement one thing as soon as possible, which was to carry out large-scale planting in the Gaochang area.

After the fall of Gaochang, the Tang Dynasty established the Protectorate of the Western Regions. That area was a good place to grow cotton.

"I understand the humble position!"

After Hegan Chengji went down, Li Chengqian played with the cotton plush and became more and more delighted the more he looked at it.

"Your Highness."

"What is this?"

When Chang Sun Chong and Li Zhi came in, they were both very curious.

"It."

"A baby that will change many things in the future."

Li Chengqian said with a smile, without further explanation.

The two were confused and did not ask any further questions.

……

Lu Dacheng stood by the Wei River and was worried, but no matter how worried he was, he still had to take action.

With strong support and the help of his friends and relatives, he began to build it by the Wei River.

It's not complicated and the principle is very simple.

A group of skilled and experienced craftsmen built a waterwheel at an astonishing speed and carried out preliminary trials.

"can!"

"Old Lu, this method works."

"You see this one is full, and that other side can be pried open."

A craftsman shouted excitedly.

Others were also quite excited, but were soon poured a bucket of cold water.

Because the stone carried by the wooden pole on this side was too big, the waterwheel on the other side only turned once when the water was full and then stopped.

Lu Dacheng was disappointed and immediately looked for the reason.

"Do you want to change the stone to a smaller one?"

Someone suggested: "If it's too heavy, the waterwheel won't be able to turn at all."

"Maybe the waterwheel is too small, why don't we build a bigger one?"

“This is a waste of time.”

"I think it's feasible."

"Let's see what Old Lu has to say."

The craftsmen all looked at Lu Dacheng, and Lu Dacheng was also very conflicted.

Using smaller stones, the waterwheel can certainly be pried up, but what if it can't be turned back on?
Rebuilding a large cart would take more time.

"how's it going?"

Zhang Liang is here.

He was very worried about whether this group of craftsmen could complete the prince's instructions.

Although it was not given to him, as the Minister of Works, how could he not be responsible if the people below did not do their job well?
"Meet the Duke."

"Forget about that, let's talk business, how is it going, can it be done?"

Zhang Liang asked.

Lu Dacheng said: "It can be done, but it will take a lot of time."

Zhang Liang raised his eyebrows, "The prince has ordered that we cannot delay."

"It's been two days, and you still haven't accomplished anything?"

"How do I explain this to the prince?"

Lu Dacheng was anxious, but didn't know how to answer.

"Hey, what are you doing?"

While everyone was being questioned, a young man squatted beside the waterwheel they built, moving his hands and feet as if he was measuring something, and shaking his head slightly from time to time.

This attracted everyone's attention and the craftsman was a little unhappy.

What does shaking your head mean?
Zhang Liang looked a little hesitant and asked, "May I ask if this is Doctor Taichang, Taoist Priest Li Chunfeng?"

"Oh? The Duke of Yun actually knows me?" Li Chunfeng was quite surprised. "I didn't expect that my name would reach the Duke's ears. I am so lucky."

At this moment, Lu Dacheng and others' expressions changed slightly. It turned out that he was a Doctor of Taichang and a Taoist priest.

Compared with others, what are they?
"Master, what a wonderful remark! I happened to see you discussing Taoism with Your Majesty, so how dare I forget it."

Zhang Liang smiled and asked, "Why is the Taoist priest here?"

By chance, Li Chunfeng was planning to come to the Wei River to collect folk songs. When he saw Lu Dacheng and his men busying around, he came over to take a look out of curiosity.

He also has some experience in craftsmanship.

"Master, can you see something wrong?"

Zhang Liang asked.

"The waterwheel is too small, the stone is too big, the wooden pole in the middle is too short, and the fulcrum is too simple."

Li Chunfeng looked at the waterwheel and said, "If you want to use a wooden pole to pry a huge rock weighing thousands of pounds, the waterwheel must be large enough to have sufficient water power. In addition, this wooden pole is too thin..."

"Even if you pry it, it will break."

Zhang Liang said, "You don't know, Taoist priest, this is an order from His Royal Highness the Crown Prince. He has issued a command to the craftsmen in the Ministry of Works, and they must make it."

He explained the whole story and said, "Since the Taoist priest has such insight, I hope he can help me."

"otherwise……."

Zhang Liang shook his head slightly. It was difficult to report these craftsmen, and he was in a difficult situation.

"Please give me some help, Taoist Priest."

Lu Dacheng and the others were not dissatisfied. The other party held an official position and was a Doctor of Taichang, so his status was much higher than theirs.

Definitely more knowledgeable than them.

"Well, I also want to see if it's feasible."

Li Chunfeng agreed, and with just a few words he became the backbone of the group, and a group of craftsmen gathered around him to work.

"The waterwheel must be made bigger, and so must the water bucket."

"And this fulcrum also needs to be improved..."

……

"Your Highness."

"The Ministry of Works sent someone to inform us that Lu Dacheng and his team have finished their work," Chang Sun Chong reported.

Li Chengqian was slightly surprised, "It happened so quickly, less than seven days have passed."

He smiled and said, "It seems that the Ministry of Industry is very efficient."

"I hope it's not perfunctory."

"Go and have a look."

Since his foot disease healed and his limp was no longer obvious, Li Chengqian began to enjoy riding horses.

Followed by the Embroidered Uniform Guards, they galloped all the way to the Wei River.

Before arriving, I saw a super large waterwheel in the distance, standing by the Wei River, slowly turning as the water flowed.

Wait until near.

He saw a unique scene.

Several wooden poles are staggered, some high and some low. As the waterwheel turns, they put pressure on each other, thereby prying the huge rock at the end.

"???"

Li Chengqian was a little surprised, even to the point of being amazed.

Good guy.

They have played with the principle of leverage in many different ways.

"See His Highness the Crown Prince."

As the horses approached, Zhang Liang and Li Chunfeng stepped forward to salute.

"No gift!"

Li Chengqian dismounted, whipped his horse, walked quickly forward, and looked carefully at the lever design.

"Lu Dacheng!"

The more he looked, the more satisfied he became, and he shouted loudly.

"Your Highness."

"Well done."

Li Chengqian praised generously, saying, "It seems you didn't lie."

"Your Highness, I dare not take credit for it. It was with the guidance of this Taoist priest that I was able to build the giant cart to lift the stone."

Lu Dacheng said hurriedly, looking at someone.

Zhang Liang also explained, "Your Highness, this is the Doctor of the Imperial Academy, Taoist Priest Li Chunfeng."

"Your Highness, I, Li Chunfeng, would like to pay my respects to His Highness the Crown Prince and ask about his health."

Li Chunfeng saluted again.

Li Chengqian couldn't help but be surprised. Wow, Li Chunfeng actually appeared like this.

He looked Li Chunfeng up and down. Although he had the demeanor of a Taoist priest, he was wearing the official robe of a Taichang Doctor.

"I saw it from a distance and wondered why there was a doctor of the Imperial Academy."

"I didn't expect it to be Taoist Priest Li Chunfeng."

Li Chengqian couldn't help but laugh and said, "I never thought that the Taoist priest is also good at making equipment."

"Your Highness, thank you for your praise. I just have some experience..."

Li Chengqian walked up to the large waterwheel, raised his whip and asked, "Did you give me this advice?"

"Yes."

"good."

He paused and said, "Master, you should know about gears, right? Well, that is, ratchet."

"I know." Li Chunfeng said.

Li Chengqian smiled and said, "Tell me, if we apply the principle of this wooden pole to the gears and the power of the waterwheel, can we pry a force of ten thousand pounds?"

Hear the words.

Li Chunfeng frowned and thought, while Lu Dacheng and others were also secretly calculating.

Li Chengqian was not in a hurry to disturb them and turned back to continue studying the principle of leverage.

It has to be said that the principle of leverage has been known to people for a long time.

However, there is still some lack of knowledge on how to use it to its fullest extent.

His current purpose is actually very simple.

We just need to guide them slowly and develop the hydraulic technology tree for Datang.

Li Chunfeng's appearance was a bit unexpected.

But it was a pleasant surprise.

The best thing about this kind of Taoist talent is his wild imagination and his ability to invent and create.

Moreover, they are really not afraid of death and dare to think, act and do.

"What your highness said is theoretically feasible."

"But, to succeed, maybe..."

Li Chunfeng was a little hesitant and didn't dare to make a guarantee.

“Don’t be afraid of failure.”

Li Chengqian said calmly: "Every failure is a way to accumulate experience."

"If you fail, the next step is to succeed normally."

"so."

"I plan to set up a Tiangong Workshop by the Wei River to research and invent Tiangong methods."

"The Taoist priest will serve as the Grand Secretary of Tiangongfang and take charge of all the affairs of Tiangongfang."

Ok?
Li Chunfeng was dumbfounded.

He was just trying to help others out of curiosity, but how come he got himself involved?

"Your Highness, this is not my ambition, and Heavenly Art is not something I am good at."

He gave up his position as the Doctor of Taichang and ended up being the Grand Secretary of Tiangong. No matter how you look at it, it's a loss.

"I am not discussing this with you."

"This is the prince's order!"

Li Chengqian said in an unquestionable tone.

You showed up on your own and you still want me to let you go?

how is this possible.

He was worried that Tiangongfang had no leader.

Since you, Li Chunfeng, love to show off so much, you must have some ability.

Who else but you?

I, the crown prince, am still discussing things with you. What a joke.

No one in the court, whether civil or military, dared to disregard the prince's order.

How can a mere Doctor Taichang like you really do anything extraordinary?
"Duke of Yun."

"The construction of Tiangongfang will be handed over to your Ministry of Works."

"Everything should be discussed with Taoist Priest Li."

"As for the money, it will be paid by the East Palace."

When Li Chengqian said this, he suddenly thought of something and said, "Master Li, since you are a Taoist disciple, you should be familiar with other Taoist disciples, right?"

"I will issue an edict to summon all Taoists and alchemists in the world to Chang'an."

"Giving me a list is better than looking for a needle in a haystack."

"Otherwise, I can only be a Taoist in the world."
