"This...what is this?"

After a while, Lu Yuan could speak.

Yuan Ling looked unfathomable. This was a dynamic physical equation, and he used Arabic numerals for his calculations.

Arabic numerals originated in Baghdad, an Indian scientist in ancient India. They were introduced to China around the 8th century AD and were not accepted by the Chinese writing system at that time. They were not officially used until the first year of Guangxu.

At this time, the people of the Tang Dynasty could not recognize Arabic numerals at all.

Not to mention that the Chinese do not recognize it, even the ancient India, which invented Arabic numerals, has not invented one to ten now.

Therefore, Lu Yuan looked at the equations as if he was reading a heavenly book.

"This is a way of calculating numerology. As for the origin of these numbers in ancient India, they will be simpler than our numbers and are more convenient to use for calculation."

Yuan Ling just chose a simple explanation, but without a certain foundation in mathematics and physics, he couldn't understand it at all, and he couldn't explain it even if he really wanted to explain it.

You can't start with years in elementary school!

Lu Yuan had a deep understanding of it, but he didn't know how to ask, so he opened his mouth but still couldn't ask.

Yuan Ling had a good impression of Lu Yuan, the Minister of Works. During the period when he was studying the livestock trolley, he was the most diligent and asked the most. His desire for knowledge was no worse than that of Yan Lide. He was not stingy with advice and answers. He had no private information except those things that really couldn't explain clearly.

He paused and said, "If the minister wants to learn, I can teach you. But this is extremely profound and does not have a deep foundation in numerology, so don't talk about it."

Lu Yuan said with some doubts: "No need to verify or compare, just this really works?"

Yuan Ling said: "Whether it is successful or not, you will know it just by trying it."

According to the ratio given by Yuan Ling, Lu Yuan also made two livestock cylinder trucks, one larger and the other slightly smaller. In comparison, there was no problem with the power.

Lu Yuanxin bowed to Yuan Ling in convincingly and said, "What the King of Shang learned is amazing, and the officials admire him so much."

The success of the animal power trolley greatly stimulated the morale of the Ministry of Works.

Yuan Ling made a big move and waved his hand to study the high-rotor truck.

The high-rotor truck is based on ten feet and consists of upper, lower wheels, simple cables, brackets and other components. Half of the lower wheels are buried in the water, and the water draw elevation can reach ten feet. The two barrel trucks need to cooperate up and down to twenty feet. It is the most difficult one among barrel trucks, but it is also the most necessary form.

Because the high-rotor truck serves the Yellow River, Yangtze River and Huai River, which are rich in water resources, the results are most significant.

When the high-rotor truck was about to be completed, Yan Lide came to Yuan Ling with a serious look on his face and said, "King Shang, it's trouble. The high-rotor truck is too high and too big, and the power required is very human. Ordinary livestock can rotate. If it is made according to the drawings, there will be the disadvantage of insufficient power."

Lu Yuan had not taken so much into consideration. After Yan Lide's reminder, he suddenly woke up and exclaimed: "There is insufficient power, isn't that high-rotor truck a dead thing?"

Yuan Ling was confident and said, "This matter was long been considered. We can build a vertical windmill near the high-rotor truck to use wind power to drive the water-rotor truck. With the help of Feng Shui, it is enough to drive the high-rotor truck."

Yan Lide was stunned: "Wind?"

Lu Yuan's heart moved and blurted out: "Just like a sea boat, with the help of the power of the sails? Good idea..."

Yuan Ling unexpectedly glanced at Lu Yuan. The vertical windmill was a windmill invented by the Song Dynasty to assist in the high-rotor truck. This was never seen in the Tang Dynasty. Lu Yuan actually reacted earlier than Yan Lide, which was enough to make him look up to him.

He specifically depicts the appearance of wind equipment, which is simple and practical, and easy to understand.

Yan Lide sighed: "The Shang King's wonderful ideas, Zhang Heng and Ma may not be able to do it."

Lu Yuan was speechless.

East Palace!

Li Chengqian looked at the confidant in front of him with some dissatisfaction and said, "It's been so many days, there's no news at all, what should I do?"

Lu Yuan was convinced by the local people, and didn't know how to talk about it.

Li Chengqian was even more dissatisfied with this and always felt that everything was not going well, especially after the censor asked Li Tai to report to Li Shimin to reject it, he felt a lot of anger in his heart.

According to the dynasty, when the prince reaches a certain age, he should be released from his official position and go to his fiefdom to exercise government affairs.

Li Tai had already reached the age of an official, and Li Shimin suppressed him again and again, and was reluctant to leave his beloved son and leave him to his fiefdom.

Li Chengqian felt very uncomfortable, and always felt a sense of fear, feeling that his father left Li Tai to replace him as the prince. Thinking of his father, he never treated him as tolerant as Li Tai, and his uneasiness became increasingly serious.

After being angry, Li Chengqian whispered loudly: "You are today, and you are promoted by the Lone King. Now you can't do any small things?"

Lu Yuan hurriedly said, "Your Highness the Prince's promotion is a kindness, and the officials dare not forget it. But the prince's fate is really impossible to investigate. The King of Shang is extremely talented, and the officials are not in a hurry to slap their horses, so how can they find flaws?"

"The Lonely King doesn't believe it!" Li Chengqian said angrily: "How could he be a confused waste suddenly make a scattered cart like a magical thing that benefits the world? The Lonely King definitely doesn't believe it. There must be a reason for this. The Lonely King heard that he was inspired by He Chou and brought out a large number of letters from He's mansion. This scattered cart should be He Chou's merit. Li Yuanai was just a false claim. The Lonely King was in the Eastern Palace and could find out this matter. You have been by his side for so long, and you can't find out at all?"

Lu Yuan couldn't say anything. Thinking of every bit of these days, he couldn't say anything slandered Li Yuanai, and said, "Your Highness, the King of Shang has never avoided He Shaojian's contribution. However, the officials can feel the King of Shang's research on the trolleys. He firmly believes that even if there is no He Shaojian, the trolleys can still succeed, and it is just a little delay. The King of Shang is indeed a real talent and knowledge. The official has benefited greatly from these days by his side. He is definitely not the incompetent person he calls..."

"Stop!" Li Chengqian never expected that the person he promoted would dare to disobey him like this, and he was even more angry: "Bastard, the Lone King actually raised a Zhongshan wolf, get out of here!"

Lu Yuan kowtowed three times and retreated.

Li Chengqian's chest was undulating, and he was so angry that he said, "Li Yuanai!"

In fact, he has no deep hatred with Li Yuanai.

He couldn't vent the various pressures and fears brought by Li Tai to his younger brother, and simply wanted to find someone to vent. It just so happened that Li Yuanai refused to give him "The Song of Ruo Lu in the Courtyard" and wanted to vent his anger.
