Datang broom star

There are a few big trees on the side, and the birds on the trees are startled to fly.

What a loud voice!

Huang Wan couldn't help being secretly surprised.

puff!

Something landed on his forehead, and it was still warm.

Huang Wan reached out and touched the black and white bird droppings

old man!

Li Yao accompanied Jia Pingan with a smile, "Are you going to try sailing?"

"Yes, call a dozen or so for the strong ones in the family. Also, get some wooden planks to stir the pool water, and some thick cloth that can fan the wind."

Jia Ping'an acted casually as if he was at home.

Huang Wan lowered her body and said, "It is said that Junjun Jia and Yingying's family have a good relationship, but now it seems that it is not just a friendship, it is a good relationship between the whole family."

Yan Liben nodded, remembering what happened to Li Jingye in Sanmenxia last time.

The pool is very large, and there are a few ducks swimming leisurely on it. When they saw a group of strangers coming, they quacked and ran towards the shore.

Put the model into the pool, the sharp-bottomed boat shakes, and the flat-bottomed boats are stable!

Huang Wan smiled and said reservedly: "Let's try later."

Li Yao came with people, a dozen pieces of wood, and several large pieces of thick cloth.

"let's start."

More than a dozen people moved independently on the shore. Some people stirred the pool water with wooden boards, while others used thick cloth to fan the wind. Suddenly, there was a strong wind and waves in the pool, as if a typhoon was coming.

This scale is much larger than what Jia Pingan simulated at home.

The two boats swayed violently. The flat-bottomed boat seemed to be hanging back and forth, while the sharp-bottomed boat seemed to be swinging back and forth, but it moved with the waves and was extremely stable.

"what!"

A craftsman said in surprise: "It can be stabilized?"

Huang Wan sniffed, "Ahem! This storm is smaller."

Li Jingye stepped forward, "I'm coming!"

He took the plank and stirred me vigorously!In an instant, the vicinity of the two ships was turbulent.

"Gale!"

Huang Wan shouted.

"Strength!"

Those big men tried their best to fan the wind, and the wind blew up for a while.

The ship designs of later generations all have equipment that can imitate the water regime, but here we can only play artificially.

The punt is already in jeopardy

"Hold on! Hold on!" Huang Wan clenched his hands into fists, his face flushed

In the midst of his prayers, Li Jingye shouted loudly, the agitation was so strong that the waves rushed over and capsized the flat-bottomed boat.

Li Jingye froze for a moment, "Brother, did I do something wrong?"

You did a great job!

Jia Ping wished he could kiss him.

The craftsmen were overjoyed, and without taking off their clothes, none of the craftsmen threw themselves into the pool, and bravely swam towards the sharp-bottomed boat.

Yan Li didn't know much about shipbuilding, so he looked at Huang Wan.

Huang Wan's lips twitched, "Cough! Cough! Cough! Why is this?"

A group of people were looking at Jia Pingan.

The craftsman in the water caught the sharp-bottomed boat, and when he heard Jia Pingan want to explain the problem, he kicked the water frantically with both feet, and even shouted regardless of his dignity: "Mr. Jia, wait a moment! Wait a moment!"

If this mystery cannot be solved, everyone will have trouble sleeping and eating.

"Brother, go drink."

Li Jingye took the opportunity to ask for leave today, and was going to take his brother to Pingkangfang to drink and shake his ass.

Yan Liben said sharply, "Business matters!"

Jia Pingan smiled, "First of all, you always feel that a sharp-bottomed boat is not easy to maintain balance, but on the contrary, it is quite good to keep a sharp-bottomed boat in balance; second, the sharp-bottomed hull is good for breaking water, so the resistance of the boat is smaller. It will be faster and third, resist wind and waves”

Jia Ping breathed a sigh of relief, Huang Wan couldn't wait to ask: "Why can it resist the wind and waves?"

Poor people, the previous research ships were all flat-bottomed boats. Jia Ping’an said: “A considerable part of the hull of a sharp-bottomed boat is underwater. How much force is needed to push the bottom of a ship as big as sea water?"

"I understand."

A craftsman said ecstatically: "This sharp-bottomed boat has a draught below, and if it encounters wind and waves, the bottom of the boat can stabilize the boat. Such a wonderful idea makes use of the wonderful water!"

Huang Wan closed her eyes, then opened them. Yan Liben had already reached the edge of the pool, pushing the sharp-bottomed boat to one side, "It's not easy to push!"

Of course, it is not easy to push. When people stand in the water and walk, they will feel the strong resistance of the water.

"Okay?"

Jia Pingan didn't take this matter seriously, "The details of this ship still need to be improved, so I'll leave this to you. Then report it to the court and pay close attention."

At this moment, his mind is full of the scenes of the landing battle. In the smoke, the entire sea is covered by the sails of the Tang Dynasty warships. The sharp-bottomed boats approached one after another, and then the catapults projected the gunpowder packages to the shore; the crossbowmen frantically fired crossbow bolts The ships landed, and the soldiers began to land and fight

So comfortable!

Wa country!

Jia Ping'an only has the Japanese country in his eyes!

When the ship was built, he vowed to find a way to promote the Tang Dynasty's expedition to the country of Japan even if it was torn apart.

for sure!
