Li Zheng helped Brother Zhu up and said, "Take everyone to get the money."

After saying that, seeing that Brother Zhu was still stunned, Li Zheng changed his face and said, "Hurry up and take the wages to work. If you don't go, you will be deducted your wages."

Hearing this, everyone went to Li Yi Mansion to receive wages in an orderly manner and left quickly.

I have to say that these people ran away with money quite quickly.

Li Yifu said: "Chang'an Order, are these people really reliable?"

Li Yifu still has some doubts.

Li Zheng said: "What? Don't you believe them?"

Li Yifu whispered: "You say that the people who do intelligence in Your Majesty's hands are too ordinary, they all look like people from the market."

Li Zheng looked at the backs of Brother Zhu and others and said, "Then what do you think it should be."

Li Yifu said: "I think it should be the kind of person who is very skilled and has no exposure."

Li Zheng said: "Is it the kind of person who doesn't usually speak much? You can tell at a glance that the man is a master?"

Li Yifu nodded vigorously, "That's right, shouldn't it be like that?"

Li Zheng sighed and said, "Li Yi Mansion, the most successful undercover agent can become anyone, for example, he dresses up as a hawker and interprets the spirit of the hawker just right, and makes people who have seen each other even remember him. This is the best way for people to use undercover agents to find out information."

Li Yifu nodded in a clear way, “The Chang'an Order said that if these people are inconspicuous, inconspicuous people will often play a big role.”

Li Zheng sat down again and looked at the empty bowls on the table. Brother Zhu's subordinates were still the same as before. They would never waste any food when eating. I have to say that their spirit of eating is rare and valuable, but their appearance needs to be improved, especially the habit of not washing their hands when eating, which must be changed in the future.

After packing up the dishes, Li Zheng lost his appetite.

These days, the academy's research institute is very busy.

Li Zhi lived in the research institute for several consecutive days.

Ten days later, Li Zhi took a small boat about a half-person tall to the river in Jingyang.

The weapons business has always been from Chang'an to the Western Regions. Now we need to increase the business route, from Chang'an to the East China Sea, the original route must be retained.

Li Ji was also very busy these days. He was sitting by the river to take a nap when he saw Li Zhi bringing a group of children from the academy to the Jingyang River.

What Li Ji cares about the most was the strange-style boat that Li Zhi was holding.

Although you can tell at a glance that it is a sailboat, I always feel that it looks strange.

Li Ji walked up and said, "Your Highness King Jin, did you make the wrong ship?"

Li Zhi looked at the ship in his hand and said, "Why are you wrong?"

Li Ji said: "Why is your bottom sharp? This kind of ship cannot be put on the ground, let alone going into the water."

Li Zhi scratched his head and said, "I don't know why the teacher designed this way."

Li Ji sneered: "That boy Li Zheng is in Jingyang all day long. He has seen any big ship? There is a huge tower ship over Luoyang. Have he seen it?"

Li Zhi nodded and said, "That teacher must have never seen him."

Li Zhi lifted the sailing model in his hand and said, "But the experiment still needs to be done."

Li Ji said: "The same is true for your academy. Do more research that is beneficial to the country. What's the use of doing this kind of experiment?"

As he was talking, Li Zhi put the boat into the river.

Li Ji looked at Li Zhi's movements.

But the next second, Li Ji's expression changed from contempt to solemnity.

This small boat actually floated steadily along the water flow, and it was quite fast.

Li Zhi opened the canvas on the mast on the model, and as soon as the canvas was opened, the wind blew the boat and sailed quickly.

Moreover, as the ship moves, the ripples of the water flow into triangles become the tail of the ship, and the speed is quite fast.

Li Ji had never seen a boat with such a smooth tail.

Li Zhi ran along the boat all the way, recording the data of the follow-up.

Li Ji stood there in a daze, unable to understand for a moment.

After chasing the boat for an hour, Li Zhi picked up the boat from the water.

Li Ji walked up and asked, "How did this ship do it?"

Li Zhi smiled and said, "Actually, it's all some physical knowledge."

Li Ji said in confusion: "What physics knowledge?"

Li Zhi said: "In fact, the shape of the inverted triangle at the bottom of the ship is intentional, because the bottom of the ship is sharp. Such a ship is less resistance to the water flow and has a very fast speed."

Li Ji recalled the triangular ripples that were almost cut from the water surface of the boat. It seemed that this was true. Li Zhi said again: "The other advantage of inverted triangles is that the bottom of the boat with inverted triangles is that the bottom of the boat with inverted triangles is easier to increase the displacement, so that the larger space at the bottom of the boat sinks into the bottom of the water. The boat does not need to be too big or too heavy. The bottom of the boat with inverted triangles is not small, and because the buoyancy direction on both sides of the inverted triangles is more concentrated and more stable."

Li Ji frowned and thought.

Li Zhi said: "Did the general understand?"

Li Ji frowned and looked at Li Zhi, and said in a tangled manner: "You said that this dress will not overturn. How could the bottom of the boat with an inverted triangle not overturn?"

Li Zhi took out a triangle pillar made of wood and handed it to Li Ji and said, "Put this triangle on the water surface, the general can also try it. In fact, it is all the same principle."

After saying that, Li Zhi walked towards the academy.

Li Ji was a little confused when he looked at the triangle pillar in his hand. He heard Li Zhi's words and wanted to put it in the water?

Look carefully at the river surface, Li Ji put it in the water, and as Li Zhi said, two sides were in the water, and the flat side was on it.

Li Ji whispered: "It's so wise."

I didn't expect that the inverted triangle could be used on shipbuilding.

Li Ji was thinking about building a ship?

Thinking of the business in Japan, Li Ji immediately walked to the horse circle in the village.

At this moment, Li Zheng was sleeping under the shade of the horse circle.

"Boy! I have something to ask you!"

Li Zheng opened his eyes a little and saw Li Ji's stinky face closed again, "Do you know if it's lunch break now?"

Li Ji stared and said, "I have something important to ask you."

Li Zheng turned over and said, "It is a very unethical thing to disturb people's dreams."

Li Ji nodded and said, "I understand. You asked the academy to build ships to cross the sea to do business in Japan."

Li Zheng said: "General, I studied it too late last night. Can I calm down for an hour or two and let me sleep for a while?"

"OK!"

After Li Ji finished speaking, he sat down and waited for Li Zheng to wake up.

The afternoon is indeed a good time to take a nap.

Li Ji enjoyed the coolness under the shade of the trees and was sleepy.

I looked at Li Zheng who was sleeping again, and his eyelids couldn't hold on to the fight.

With a sniff for a while, Li Ji slowly closed his eyes.
