Off the coast of Lushun, there were five warships moored on the periphery of the ice floe area, and Yang Yiteng and several shipowners on board looked at the endless ice floe area and were worried.

"How many shipowners, what should I do? The Grand Commander must be in a hurry to get the goods on the ship, but this place is still dozens of miles away from Changsheng Island, let's think of a way! Yang Yiteng put down the binoculars in his hand and asked several shipowners around him with a worried brow.

The sea is frozen, not all of which are walkable, and there are many scattered ice fles on the edges, and the further you go, the denser the ice floes become, until the ice surface is walkable.

Ordinary ships, at this time, it is impossible to run Liaodong, so the big guy will not step on this big problem, even if the five shipowners are rich in the rivers and lakes, for a while, they are helpless.

Zhou, who has always been resourceful and resourceful, and claims to be Zhuge alive, stroked his long beard with his hand, and spoke calmly: "Lord Shi, it is almost impossible to transport the goods on the ship to Changsheng Island, but I can send someone to Changsheng Island to deliver a letter." ”

Yang Yiteng asked eagerly, "What way?" Zhou Lao, please come. ”

Several other shipowners also looked the same, and some of them secretly despised it, all of them were at this juncture, and they had to put on an unfathomable look, and they really regarded themselves as Zhuge Liang, so they almost pretended to be elegant with a feather fan in their hands.

"Greeting, let the sailor make a small wooden boat that does not need to be too big, but can seat two people and the necessary food.

It doesn't need to be too strong, as long as it doesn't leak too much, there are ready-made wooden boards, waterproof putty, paint, hemp rope, etc. on board, which can be caused without too much effort.

Elder Shi can order two soldiers to take a small boat through the ice floe area, and when they reach the dense ice floe area, they can chisel the ice and slide, the boat is not heavy, the two of them can do it, and when they reach the ice area, they can walk to Changsheng Island. ”

Zhou Shipowner finally said his method, not to mention, this method is quite feasible, and it is also the only way to send information to Changsheng Island, Yang Yiteng immediately accepted it.

It is really not difficult to build a canoe-like boat with a few planks, and it does not require quality, it is a one-time item, and it is done with a tinkling of a boatman who knows how to carpenter.

The two sailors selected by Yang Renteng carefully sat in the boat, and one of them took a special oar and began to paddle, turning left and right from the gap in the ice floe, and moving forward with difficulty.

When they arrive at the dense ice floe area, one person first gets on the large ice floe, then pulls the boat, and let the other person also get on the ice floe, and the two work together to pull the boat onto the ice floe, and the two continue to sit in the boat, turn the oars upside down, and use specially nailed iron nails to chisel and slide on the ice surface.

When a person sits in a small boat, he is not afraid of sliding into the ice gap on the ice floes, which is equivalent to wearing a pair of extra-long shoes or bringing his own small wooden bridge.

In this way, the two sailors went through hardships and finally set foot on the icy area, and the two immediately abandoned the small wooden boat and hurried all the way, which lasted two days, and finally set foot on Changsheng Island.

The two sailors didn't know where Yang Wenli was, and they didn't ask anyone else, so they went directly to the commander's mansion to report the news.

On this day, Xiao Yan'er happened to wear a new robe sewn by two servants, with snow-white fox fur inlaid on the sleeves and neckline, and she liked it very much, so she went to the outside of the Commander's Mansion to show it, stinky and beautiful, and wanted to get some compliments.

As soon as she reached the door, she heard someone talking loudly, and she stepped forward like a little adult and asked, "What are you doing?" What kind of system does it become to make a loud noise in front of the Commander's Palace? ”

The two sailors and the guards at the door hurriedly bowed to her in unison: "Madam"

"What's the matter?" Xiao Yan'er just nodded slightly as a return gift, and then asked in an old-fashioned manner. Don't look at her young age, she is quite good at posing music, and she holds a lady's style all day long.

"Madam, the little ones are the sailors who purchased sulfur, lead, copper and other materials from Dongying, because the sea is frozen, the ship can't reach Changsheng Island, we even the eldest people, specially sent the little ones to report to the commander, I don't want to worry Madame, and ask Madame for forgiveness!"

Although Xiao Yan'er is young, her identity is there, and the two sailors dare not slack off, and one of the sailors hurriedly explained.

"Really, these little things also bother me, why don't you go and inform the Grand Commander, hum! All of them are like wooden people. ”

Xiao Yan'er heard that it was none of her business, so she complained, turned around and went home, she was no longer in the mood to go out to show off, besides, it was strange outside that it was cold, she only came out for a while, she felt that her hands and feet were frozen, and she still went back to the room to lie on the kang comfortably.

A few guards seemed to have been injured by 10,000 points, and complained wildly in their hearts, don't bother you with any trivial things, you are a master who doesn't care about anything and can only play greedily, okay?

One of the guards took the two sailors to the workshop to find the commander.

Since Yang Wenli proposed to attack Yongning and said that Yongning had two horse ranches of Tartars, he was very anxious and didn't know when Jiannu would return to Liaodong? When will you attack Eternal Island? At this time, the sea is frozen, and it is impossible to escape from the sea.

Now he only has a few thousand troops, and the army of Jiannu is still not able to catch it, so he has to find a way to resist the enemy, he thought of a very simple but powerful grenade, the kind that can be fired with ballistas and grenadiers, of course, it can also be thrown manually, and one bullet can be used for multiple purposes.

Although the grenadier canister is not yet available, the size of the grenadier Jane must be considered. Things seem to be back to square one, the grenadier is only so big, and manpower can only throw a few catties of grenades, if black powder is used, the power is too small, maybe the grenade will only explode into two petals, that is to say, he has to develop high explosives, and the grenade is impossible to also engage in primitive ignition launch, which is not in line with his identity as a reborn, if you want to do it, you have to pull the fuse to delay the ignition, which is also a big problem.

In fact, in the past few days, he has been developing chemical experiment supplies such as glass test tubes, beakers, and alcohol lamps.

He can fire glass, and he has the lost-wax method of precision casting process, and there is no difficulty in firing these glassware, the difficulty lies in how to engrave the scale of these objects.

This is a big problem, how to make the volume and weight linked, and how to determine the standard of one meter, one kilogram, one liter, it is difficult to do it in his current conditions, in fact, in ancient times, kings used their own hands or feet to determine the length of an inch and a foot.

These very casual weights and measures are very different from the international standard system, they are all decimal places, I don't know how many digits there are, but he happened to know that the carpentry ruler of the Ming and Qing dynasties was 31.1 centimeters.

So Yang Wenli ordered his men to go down to the ship to find a standard carpentry ruler, and personally began to measure and convert it into one meter, which is related to the standard of eternity, and he can be said to make the world's first standard meter balance with a sincere attitude.

What is the most stable and more durable thing in the world, not gold and silver, not iron and copper, but those ordinary stones that we ignore, stone has gone through hundreds of millions of years of wind, frost, rain and snow, is the most balanced substance, used as a bed foundation for ultra-precision machine tools in modern times, it can be seen how the stone is stable.

Yang Wenli did not have a fake hand, he used the stone carefully, and meticulously polished and cut, and made the world's first international standard ruler.

Yang Wenli took a long breath, stood up and said to Wang Rucheng beside him: "Rucheng, this is a standard measuring stick I made, the length of which I define as one meter, which is the standard for all our future weights and measures, one meter ten, one minute ten centimeters, one centimeter ten millimeters, using the decimal system, which is easier to calculate."

In addition, the length, width and height of one meter of the container, that is, one cubic meter, the water containing pure water is one ton, the same way, one cubic decimeter of pure water is one kilogram, one cubic decimeter is also called one liter, this is the length, weight, volume of three standards ......"
