"Imperial Father, why are you looking at your son like that?”
Li Chengqian asked with a strange expression when he saw Old Li looking at him with an uncle's smile.
Old Li smiled brightly and said,"
"Chengqian, this Quyuan Plow was designed by you. With it, the people of the world will be at ease.
You have contributed greatly to this matter. You are the greatest contributor to solving the problem of the people's spring ploughing.”
Haha!
Li Chengqian secretly rolled his eyes, but he still had to give face. He said,
"Imperial Father, what are you saying? Imperial Father is the one who leads well. Your son just happened to meet.”
Li Chengqian wasn't the kind of person with a negative EQ.
As expected, Old Li was even happier. He continued,
"Chengqian, there is something that father does not understand.
Can you explain why this light curved shaft plow can plow deeper than this straight handle plow?”
Old Li was puzzled by this question.
Everyone present was puzzled. After all, this was not quite in line with their daily experience.
Li Chengqian looked at everyone present and smiled at Old Li.
"Imperial Father, the reason is actually very simple. The secret that caused this situation to occur lies in Qu Yuan.”
As he spoke, Li Chengqian squatted down and drew a few strokes on the ground.
"Imperial Father, please take a look. The arc here represents the curved shaft, and the straight line here represents the straight shaft.
When the ox pulled the plow forward, it provided a forward force, didn't it?
But if you want to plow deeper, you must have the power to go down, right?
This side of the plow is a straight line. The strength of the ox and the weight of the plow itself…"
Li Chengqian raised his head and saw that his father and the ministers were all dazed.
Very clearly, they were even more puzzled by Li Chengqian's explanation.
Sigh, being uncultured is really scary!
Li Chengqian silently cursed and tried to say simply,"
"In general, if a straight plow wants to plow deeply, it needs to rely on its own weight to achieve its goal.
However, the curved shaft plow was different. The strength of the ox could also have the effect of deep ploughing, so it could reduce the weight of the main body!”
"Your Highness the Crown Prince is really too intelligent. We all understand now!”
Cheng Yaojin suddenly shook his head and said loudly.
"Not bad! Even a boor like me knows what's going on. Your Highness the Crown Prince is really amazing!”
Yuchi Gong also spoke up.
With these two people taking the lead, the rest of the people also agreed or nodded in agreement.
Seeing this scene, Li Chengqian's expression was somewhat strange.
He finally understood why Old Li liked the officials 'rainbow-like farts. It turned out that this feeling was really good!
In fact, the improvement of the curved shaft plow on the foundation of the straight handle plow was far more than this.
However, Li Chengqian knew that even if he explained everything, these people present would probably only know half of it.
Therefore, he was too lazy to waste his energy.
Old Li, who was standing beside him, had an awkward expression. Others might not know what Li Chengqian was mumbling, but he knew.
He had clearly heard this little rascal lambasting them for being uncultured.
This brat…
Old Li glanced at Li Chengqian, who looked obedient on the surface, and said to everyone,
"Everyone has already witnessed the effectiveness of the Quyuan Plow.
In a few days, I will send a copy of the production method to all the prefectures and counties…"
"Father, have you forgotten something?”
Just as Old Li was passionately giving his speech, Li Chengqian reminded him in a low voice.
"What is it?"
Old Li was confused.
Li Chengqian pursed his lips and whispered again,"
"Imperial Father, we have only tested that the curved shaft plow is more efficient and better than the straight handle plow.
But I don't know if a horse can pull this curved shaft plow. If a horse can do it…"
Before Li Chengqian could finish, Old Li instantly came back to his senses.
That's right, if a horse could pull a curved shaft plow, that would be the best news.
Just now, he was so stunned by Qu Yuan Li's stunning performance that he had actually forgotten about this matter.
"Men, bring a horse over, no…bring two horses over.”
Thinking of this, Old Li did not delay and ordered again.
Moreover, he had also learned and applied the comparison system that Li Chengqian had mentioned before. He was prepared to use two horses for comparison.
Under everyone's watchful eyes, the horses equipped with the curved shaft plow and the straight handle plow respectively cleared a small piece of land.
The results came out very quickly.
As everyone knew, it was difficult to plow the land with horses with straight plows, and the depth was not up to the requirements.
However, the horses that used the curved shaft plow were different.
Its plowing speed was actually not slower than that of the cattle.
Moreover, due to the characteristics of the curved beam plow, it could also perform well in the depth of the cultivated land.
"Your Majesty, this is really great. I didn't expect that this Quyuan Plow could even be used by horses.”
"That's right. Our Great Tang doesn't have many oxen, but we do have many horses.
Originally, if this curved shaft plow could only be used by cattle, it would be useful to the common people, but it would also be limited.
But now, it's different. With this curved shaft plow that can be used by horses…"
"I didn't expect that the difficult problem of spring plowing that could not be solved in all the dynasties was actually solved by this little Quyuan plow!”
"I don't know how the crown prince's brain works, to actually be able to come up with such an exquisite design!”
"The common people have no worries in the spring plowing, so they naturally have more energy to recuperate. This is a sign that the golden age is about to arrive!”
"It is our honor to witness the arrival of the Great Tang's golden age!”
……
The ministers said all kinds of things, but there was one thing that was very consistent, because they were all positive words.
Of course, Old Li could think of something that the ministers could think of.
At this moment, he was already smiling so much that his teeth could not be seen. He glanced at Li Chengqian and thought to himself,
"Although this little rascal isn't very good, his luck is top-notch.
However, this kid was bent on leaving the palace to play, which was a headache.
Fortunately, he was just curious.
Moreover, if I don't give him any money, he will probably feel bored after going out to play a few times.”
Thinking of this, Old Li felt that he had already found a good way to make Li Chengqian, this rascal, calm down.
However, Li Chengqian, who was at the side, did not expect that his Imperial Father was actually thinking about these things at this moment.
He was also a little happy.
I've finally settled this Qu Yuan Li matter. How should I spend the huge sum of thirty thousand strings?
Old Li, who was already smiling, froze.
He looked at Li Chengqian, who was thinking about spending money, in disbelief. He was full of doubts.
"Thirty thousand strings? Where did this brat get so much money?”
