An urgent letter was sent to sea from Lin'an Wharf.

This letter was to be delivered to Han Tongqing, for this letter Han Jiang specially transferred a fast boat, not to load goods, not to transport troops, this ship gave up everything from the design, only retained the pursuit of speed.

At this time, it is already winter, and it is a strong north wind from Hangzhou Bay to the sea.

Catch the wind.

The crew of the Great Song has their wisdom.

These crew members may not be literate, they don't know much physics, or even what an effective curved sail is.

But they understand the sea, and they understand the wind on the sea.

There is a group of old sailors, old shipwrights, every day to study what kind of sail, what kind of angle to face what kind of wind.

Go north, facing the north wind.

The clipper has always maintained a zigzag course, using the foresail as a ruler and the angle from the foresail to each sail as the chord, measuring the curvature of the mainsail and calculating the chord depth from both.

The clipper always went upwind at the best angle, and its speed continued to increase after exiting Hangzhou Bay.

The speed of the ship, whether it can exceed the speed of the wind.

This theory, which everyone in the world thinks is like a fool, has created a miracle in the hands of the Qian family's shipwrights.

Every hour, one hundred and twenty-seven miles.

The ship rushed north to look at every cargo ship on the route.

The ship didn't even have a place to cook, just a simple sleeping compartment, and the crew of three groups worked in three shifts, and they needed to constantly adjust the ship's attitude, constantly adjust the sails, and constantly climb up and down.

In the east of Chuzhou, the old captain of a heavy cargo ship looked at the ship that was almost flying on the sea from a distance, and said to himself: "I don't know who is in trouble again." ”

That's right, someone is in trouble.

Li Xi'er.

Since you dare to step into Han Jiang's paper pepper game, you must have the consciousness of losing all your family property.

Two days later, Han Tongqing received a letter from Han Jiang.

Originally, he thought that the letter should be delivered in at least seven days, and he was surprised that it was delivered so quickly, but after carefully checking the secret notes of the letter, he still couldn't believe that from Lin'an City to the island where he was now, all the way to the headwind, almost 1,300 miles away, how could it be possible to arrive in two days and one night.

Han Tongqing read the letter, made arrangements, and personally set up a banquet for these crew members.

Facing Han Tongqing's doubts, the captain looked proud: "Grandpa Guo, when we test, the wind can run faster than the wind, the wind blows ten miles, and we can run thirteen miles." ”

Who dares to believe the few people around Han Tongqing, who can believe it.

Han Tongqing asked: "The wind blows the sails?" Can the boat move? When the wind blows on the sails, the ship is heavy and carrying. How could it be possible to make the boat run faster than the wind, this man really can't understand. But Ben Gong is convinced? Come and drink this cup to a full seat? This father is the first to do it as a respect. ”

Indeed, Han Tongqing didn't understand.

But he didn't doubt it.

Han Jiang, this crazy kid, I'm afraid I'm very happy, right? How many good ships have there been since ancient times? Who can believe that the ship is faster than the wind.

Han Tongqing look at this ship again? The sails are more than the ship, and the sails are smaller than the ship, and I don't know how such a ship can not be blown over at sea.

Good craftsmanship, good boatman.

Three glasses in a row? Han Tongqing deliberately opened the topic? He believed that there must be secrets and very powerful craftsmanship on this ship that the world did not know about, so he asked less to save his subordinates from accidentally passing on these soldiers and horses.

Han Tongqing asked: "The pants you wear are very special." ”

"If you return to China, we have to keep climbing up and down the mast every day when we train, and the ordinary fabric will wear out in half a day? We have five sail cloths from thick to thin sent from the above in our warehouse, and our brothers picked out a few pieces of cloth with fine sails? This is good, and I'm not afraid of a slight sticky spot of water. ”

Looking for a piece of fabric for fine woven thick sails? This thing does have good water resistance.

This is not used as a mainsail cloth, but for many forerunners.

"Interesting? It seems that our hemp may become more and more insufficient. "Han Tongqing smelled a hint of fun? This is the taste of silver.

The amount of sail used depends on the number of ships shipped.

But what if this kind of fabric can be used to make clothes? Then you can also make more things, such as tents, shoes, backpacks.

This, kind of interesting.

On the same day, Han Tongqing personally wrote a letter to Han Jiang about this kind of fabric, which roughly means to expand the types of new thick linen cloth, increase the industries that can be used, and of course ensure sufficient raw materials.

The crew who delivered the letter worked hard, and they were arranged to rest in a comfortable place.

Han Tongqing personally ordered the most reliable soldier and horse to guard this sail of the boat.

Well, just wait.

When to close the net, this is a game.

The people of the Han family are inquiring about the news in Kaesong day and night, and the accounts of the Han family are constantly calculating in a small mansion outside Kaesong day and night, and they use the most stupid way to calculate the bearing capacity of these nobles in Kaesong.

After a group of merchants from the Jin Kingdom, Western Xia, and the Great Song Dynasty who had played in the black market of the Great Song Dynasty salt banknotes in Yangzhou Daming Temple came.

The paper pepper in Kaesong was completely violent.

Right now, a piece of paper pepper, contract paper for delivery in July next year. The price has reached 1,900 taels of silver.

That is to say, a half-year-old pepper mu is already nineteen taels of silver, or converted into the same prosperous money.

The price is still skyrocketing.

The rising Abs joy was no longer joy, but fear, and he had been awakened by nightmares for three nights in a row.

Someone rushed in wildly, glanced at Ab Shixi, who was sweating profusely, and walked in front of Han Si in a few steps: "This matter may be different than Shaojun expected, this is a bit unbearable, hundreds of low-grade palace maids in the Goryeo palace today pooled a sum of money, and bought two together, and the price has risen to two thousand and fifteen taels of silver each." ”

Han Si's face was a little pale, in fact, he was also starting to be weak.

After thinking about it for a while, Han Siyi gritted his teeth: "Slow down, grab it, the last time." ”

Slow release is to slowly put the contract in your hand out.

Rushing to collect is desperately receiving, in order to once again raise the contract paper price of paper pepper.

As soon as Ab Shixi heard this, he quickly stood up: "Dare to grab it again, or I will arrange to prepare for a secret evacuation." ”

"Okay." Han Si also thinks it's about the same.

Abs was relieved to hear that he could finally leave.

As for Han Si, he glanced at the note written by Han Tongqing in his arms again, which said, never leave a hand.

Taking a deep breath, Han Si walked outside, wearing a thin dress but not feeling much cold.

Blown by the icy wind, Han Si forced himself to calm down.

I remember Shaojun said that this game will be very long, be patient, it may be two months or even half a year.

But right now, it's only been half a month, and this Kaecheng is already crazy and makes people feel panicked.
