"Master Fang, this is a communication between us. It's useless for Master Fang to know."
"You are a civil servant and you don't work in water conservancy. Why are you listening to this?"
"As long as I understand it, that's all."
Li Li immediately changed his words and personally spoke to drive Fang Youwei out.
Fang Youwei gave a bitter smile. This time, Fang Youwei was not in a good position in front of anyone here with Liu Feng. He was completely in the role of a tool.
After Huang Long sent Fang Youwei away, he immediately pretended to listen attentively.
Wu Jiang coughed lightly and began to tell the story slowly and leisurely.
"It's actually quite simple. If we want to build this place up and turn it into a river where boats can pass."
"The simplest way is to dig a new river channel."
Huang Long nodded repeatedly.
"But it's not easy to do that, because the river channel that can accommodate large ships must be very wide, and rapids are not suitable for sailing."
"We calculated and came up with the data. Building a river channel is not easy."
"Of course, it's useless to tell you how we calculated it. The precise numerical algorithm is too complicated."
"I want to hear it."
Liu Feng chuckled and motioned Wu Jiang to continue.
"It's actually using various mathematical principles, such as the Pythagorean theorem, triangulation, etc."
Huang Long was completely confused. What did this all mean?
Liu Feng was also very upset. You are talking to an emperor about this? How can he understand?
To smooth things over, he said, "This will take three days and three nights to explain. It's very complicated. Let's talk about it later."
"Even if it is explained clearly, it is troublesome to calculate it clearly. I will explain it to my brother slowly later."
Of course, these data were not calculated by Wu Jiang. Liu Feng spent several nights to calculate them bit by bit.
Wu Jiang couldn't even understand the manuscript of Liu Feng's calculations, let alone asking Wu Jiang to explain such a rigorous mathematical theory clearly at this time.
But who knew that at this time Wu Jiang suddenly became dramatic again.
"By the way, I was wondering, is there an easier way?"
Suddenly he slapped his thigh and continued.
"Yes, there must be an easier way in this world."
After hearing these two consecutive sentences, Huang Long was stunned. He became interested instantly and stared at Wu Jiang again.
Liu Feng suppressed a smirk. This guy Wu Jiang was almost as bad as the Tiger Roar Army soldier who pretended to be a patient when he was in Youzhou City to attract Qian Mu's guards.
Just because he acted well in the past, he is now a centurion of the Tiger Roar Army.
The advantage of Wu Jiang now compared to that kid is that he is knowledgeable. He is definitely an excellent storyteller.
"What method?"
Huang Long asked quickly.
"Don't worry, don't worry. Let me ask you a question first. If you know the answer, I can tell you slowly."
"Tell me what the current common dimensions of the official ships of the Dali Dynasty are."
As the emperor, Huang Long had a lot of things to deal with, but he still knew about these attempts.
"Small official ships are three zhang long, medium-sized ships are five zhang long, and of course the largest official ships are ten zhang long. However, these large ships can only sail on large rivers and lakes."
Huang Long was not wrong, but these were the sizes of inland river vessels, not the sizes of seagoing vessels. The sizes of seagoing vessels are much easier to understand by comparison.
For example, at the current Xinhe Ferry, the largest ship that can reach the ferry is a medium-sized ship, and any larger ship will not be able to reach the ferry.
"You're right, but in a river like ours, big ships can't sail."
"But have you ever thought about this? We built the river into sections, and built a large sluice gate in each section.
"Then, we will sink each section of the river. What do you think the effect will be?"
Huang Long didn't understand what was going on, but he still listened attentively.
"That's a ladder? But what's the point of having such a big ladder in the water? It would make it impossible to move the boat."
"That's just bullshit."
Liu Feng turned pale.
Wu Jiang grinned and waved.
What is the most intuitive feeling at this time? Live demonstration.
Wu Jiang pointed to a relatively soft patch of soil, picked up a branch, and drew a rough diagram.
"Look, this is the first gate, right where the small waterfall is now. Every twelve steps is a section."
"Now, all we have to do is have a boat go down from this location and just open the first gate of the waterfall so that the water flow is released and the next section of the river will have more water flow."
“Originally, there was no capacity to lift these things, but after it was opened, the water flow was sufficient to lift the large ship.”
"At this time, we only need to close the first gate and open the second gate."
"When the water flow was sufficient, the boat passed through the second lock."
"All we have to do next is repeat the process over and over again."
"If there's a ship coming up, then we can do the same thing."
After finishing the painting, Wu Jiang threw away the wooden stick in his hand, clapped his hands, and acted as if nothing had happened.
"In this way, it only takes forty-eight battles to solve the problem of these hundreds of battles."
“This will shorten the construction period.”
"The second is the use of new tools, such as a crane that can be used on the water. It is a wooden boat with a heavy back and a hanger at the front. This can reduce a lot of manpower when lifting huge rocks during construction."
After he finished speaking, the whole place fell into deafening silence.
Huang Long stared at Wu Jiang's paintings in fascination. Although they were simple, they were very clear.
He watched, still muttering to himself.
"It's possible to do this. There's actually such an ingenious design."
"Yes, in this way, the entire river channel is stratified, and large ships can pass through."
“It’s really exquisite.”
"He is truly an unparalleled genius, a genius."
"If this method were used everywhere in Dali, it would solve the problem of Dali's many mountains and few roads. Water transportation would be the best way to revive Dali."
But there were still some things that Huang Long didn't say at this time, and they were all hidden in his heart.
He couldn't say it either.
Wu Jiang is a genius. At least from what he saw, Wu Jiang is a true genius. With such intelligence and talent, there is probably no one else in the whole of Dali.
He was silent for a very long time, then looked up at Wu Jiang. In his heart, apart from shock, a shock that he couldn't calm down for a long time, what remained was a deep fear of Wu Jiang.
The reason is very simple. He was shocked by Wu Jiang's excellence. If such a person wholeheartedly assisted him, the world would be pacified.
He was wary of such a person, who was one in a million in the entire Dali. If he continued to assist Liu Feng like this, then the whole world would sooner or later belong to Liu Feng.
