Bringing System to Great Tang

The propeller is the propeller, and Li Yi didn't make any detours when he designed it.

The calculation of the propeller is also calculated by him bit by bit, and the data is given at the same time.

When the craftsmen made the mold, they dig a little bit and finally figured out a mold.

When there is no problem in transmission, the propeller rotates and the thrust generated by other propellers cannot be compared.

"My Zhuangzi's craftsman is the best, what kind of five-axis linkage? What kind of printing? Do I need that precision?"

Li Yi was excited, this speed, in a water battle, can scare the enemy to death.

Li Chengqi, three adults and one child, obviously couldn't understand what Li Yi was talking about.

"Big brother, I figured it out. Don't build a steam engine train for the first time. To build a business is to build a steam engine ship."

Li Yi came for inspiration, and didn't worry about the railroad tracks anymore.

What transportation needs is speed, and what is needed is power when going against the flow.

Paddle steamers can provide power, have a large force surface, and have a lower power conversion ratio than propeller boats.

If you install a propeller and a steam engine on a ship of thousands of rocks, you can save dozens of times of time from the Yellow River to the Hukou Waterfall.

The Yangtze River is even more powerful, and the tracker needs to change his career.

Seafood can not be eaten, and water transportation is logistics. All rivers that can pass steam engines will be important channels for transportation.

Everyone still doesn't understand what steam engine trains and steam engine ships are. The only thing that everyone understands is that Li Yi can always come up with technology that people dare not imagine.

A ship that doesn't care about the direction of the wind can sail freely against the current, and now there is a faster, reversible ship.

"Brother Yi, build this ship a bit bigger, and the merchant will take the initiative to pay taxes." Li Longji thought of a good idea.

Merchants pay taxes and rely on receipts to use such boats.

Don't pay, take your time.

Slimming is not free, and money is required for the tracker. For the same goods, one ship arrives first, and the other ship arrives several days later. It is estimated that the tax will be paid back for the difference in price.

"San Lang, can I eat fresh lychees in Shu by just transporting them? Walk the Han River, and then use the horse relay."

Queen Wang has never eaten fresh lychees. What she thinks of is the lychees from the land of Shu.

In history, Concubine Yang ate lychees from Shu, not from Lingnan.

Lingnan's lychee is too late to use 800 miles to expedite.

The lychees from the Shu area can be delivered by flying in two days.

"Sister-in-law, it's easy to eat lychees. I have a way to keep lychees fresh for 20 to 30 days."

Li Yi thought of an important thing. Before storing things, candles were used to consume oxygen, but carbon dioxide was present and ethylene was also produced.

But there is another way. Preserving lychees is to control the growth response of lychees and keep them in a dormant state.

"What's a good way?" Queen Wang's eyes widened, and the little guy stared together in a tacit understanding.

If someone else dares to keep the lychees fresh for 20 to 30 days, the Queen will kick people in the water with one kick.

"Flute film, refrigerate. First wrap the lychees tightly with film film, then put them in a jar with ice cubes outside."

Li Yi said the method he could think of, the cost is high, but it is less than using the fast horse to transport money.

The flute membrane is peeled from the reed. How expensive is the ice cube?

Queen Wang blinked: "Is the flute film wrapped with ice?"

Li Yi nodded: "Yes, many fruits can use this method, such as bananas."

Li Yi swallowed, of course, he wanted more than just bananas.

He doesn't have plastic film, so he can set several layers of reed film.

If you think that the reed membrane will have air permeability, apply a layer of glycerin after a few layers of the reed membrane, and then paste the reed membrane.

In order to eat, you can fight.

Otherwise, what kind of urgent report can I send over something like banana?

The green banana is packed in a backpack, riding a horse all the way?

Four people, no, the little guy doesn't count, three people have heard of this way of keeping fresh for the first time.

"Brother Yi, easy to use?" Li Longji was tempted, he also likes to eat good food.

"Try the cucumber first, pick it off, wrap it, and place it in a place with ice cubes around it. It can't be pasted. Keep it at about four degrees above zero."

Li Yi is not sure, he has to try.

He used to wrap the cucumbers in plastic wrap and put them in the freezer. It was no problem for half a month.

Replace it with a flute film. If possible, many fruits will work.

Coupled with the new ship, the fruits from the south can be transported to Chang'an to a large extent.

The premise is that others in the middle are not allowed to stop, and the way is unimpeded.

Li Chengqi showed an expression of excitement. He found a profitable business, usually too far away, and Brother Yi didn't worry about operating it, but gave him this alliance.

Brother Yi's view of money is that when you need money, you can take out something and make a lot of money.

When you don’t need it, you sell things slowly and normally. The money never seems to be a lot, but there is always no shortage.

"Brother Yi, can you keep it fresh? Let's put it aside and find a boat. Why do you say that the propeller is placed in the water and the speed is fast?"

Li Chengqi wants to learn this.

Li Yi is speechless, brother, do you want to learn this? Work and pressure difference? Where do I start to tell you?

Do you want to learn the principle of propeller blade surface? Is it necessary to learn to advance the distance ratio?

I don't even know it, it's not an area that I can relate to.

After thinking about it, Li Yi decided to speak in a popular way.

"Look, big brother, the paddle wheel rotates and half of it will be on the water. When it turns to the top, like swimming, can you paddle on it with your arms?

A person is always paddling underwater, and a person spends half of the time on the water. The time of paddling is different.

The paddle wheel is submerged in the water. When the wheel rotates, it will fix the water first. As for the propeller, it keeps retreating.

The place where it blocks the water is just such a small piece, that is to say, the same strength is used to push it, and the paddle wheel is half idling. "

Li Yi could only introduce it like this, otherwise it would be too esoteric for others to understand.

Li Chengqi listened, smiled and nodded, meaning...I went back and thought about it slowly, but I really didn't understand it.

Li Yi controlled the rudder and slowly turned a big turn. The boat returned to the pier on the side of Lijiazhuangzi in Bashui~www.wuxiaspot.com~ The thin ice on the river was loaded away, and everyone disembarked.

The little guy was held by the queen, and his two calves kicked and kicked like the adult did.

"Brother Yi, when the river above Hukou Waterfall is open after the beginning of spring, put a boat like this on it and transport the troops and luggage, so you can directly go to Tubo at once."

Li Longji no longer thinks about the transportation of the fruit crisper, he found that the propeller is fast.

Downstream is easy to handle, but the difficulty is upstream. It turned out to be a paddle-wheeled ship.

Now that it has changed, Brother Yi was bored, and unexpectedly brought out a new thing.

The ship track test of Hukou Waterfall was successful, and the upstream and downstream can be connected.

The propeller boat placed below does not need to follow the track, the two sections are separated, and the other boats are used to travel, and then it can be changed.
