"Hello, my proprietor, it's time to eat."

Li Longji arranged for people to go outside to find someone to wash coal in Jingzhao Mansion, and Li Yi continued to copy medical books.

He found that the people of the Taiyi Department of the Tang Dynasty learned medical books very quickly, and the last time they asked Bi Gou to prescribe medicine, the imperial doctors used the medicines in the new medical books.

One is the medicine in the Ming Dynasty medical books, and the other is the medicine in the Qing Dynasty medical books.

Since you can learn and use it so accurately, let's continue to copy it.

Tired of copying, Li Yi came over to see the big scarlet-breasted parrot.

As a result, he was frightened again, and the other parrots shouted hello, and these two shouted out three 'sentences'.

"Okay, learn a few more words." Li Chengqi, who came to deliver frozen seafood, stood next to Li Yi.

The seafood from Dengzhou, the local weather is cold, and the ice begins to freeze, and the big ice cubes need well water.

The navy took the ice out to sea, fished it up, put it in a cold storage made of ice cubes, and sprinkled it with crushed ice.

When the freshness will be brought to the shore, the people on the shore prepare the ice water mixture, throw the seafood in, and put it outside to freeze solid.

A lump of lumps was separated by a straw curtain and loaded into a car to be transported to Chang'an.

The first batch has just arrived, and Li Chengqi is not ready to sell, so let's try it first.

"Big brother, I heard that Wu Zetian once raised a parrot and can recite scriptures?" Li Yi remembered something and wanted the truth.

"How is it possible, if a parrot can preach the scriptures, Buddhism does not regard parrots as sacred objects?" Li Chengqi shook his head.

"I thought of a great way to teach parrots." After Li Chengqi denied that Wu Zetian's parrot could recite scriptures, he had a flash of inspiration.

"What's the solution?" Li Yi is like asking a parrot to say a few more words.

"Speaker, your recording speaker, how hard it is to teach people sentence by sentence, that little girl is amazing, record her voice."

Li Chengqi pointed to a pair of parrots who said three words.

Li Yi: "......"

He didn't think about it at all, yes, he had a horn.

"Brother Wei knows that you are going to sell parrots, not these, parrots and starlings that you will catch from other places in the future."

Li Chengqi guessed that the price of a talking bird can go against the sky.

There is no one in his palace, and in the entire city of Chang'an, there are less than twenty talking birds.

He can't take advantage of it, and people have a bird's baby.

Now that he has the opportunity, Yi Di will raise a lot, and the big parrot will lay eggs and hatch in the spring.

"I want to open a chain of stores, and each store has a pair of parrots or starlings. Guests shouted welcome and hello as soon as they walked in. ”

Li Yi finally said his plan, foreign countries have done this.

Li Chengqi poured! Suck! One! Mouth! Cool! Gas!

It's cold outside, and there's no heat to suck in.

"Yes, yes, yes, what kind of shop to open, and then put parrots, and others go in to eat, hearing this sentence, the price of a dish should be doubled."

Li Chengqi admits how attractive talking birds are, and when he opens a store in Chang'an, there will be people who come into the restaurant to eat specifically to listen to parrots.

"Big brother asked the people in Dengzhou to dig a cellar to store ice?"

Li Yi talked about other things, the parrot is still early, and there is no hurry now.

"Having said that, I will dig a lot of ice cellars, and I always want to eat sea crabs, which are big and enjoyable.

In winter, crabs can be caught, but there is no yellow or cream, and they can only eat shells.

A few months and ten years old, the pike crab in Bohai is said to be the most delicious, but it was sent over without ice, it all stinks, and the dried crab meat is far from good. ”

Li Chengqi swallowed saliva as he spoke, greedy.

He can't go to the beach to eat crabs, he can only store ice.

"Big brother, I thought of something, a reciprocating steam engine sealed with copper gaskets, and I built it first before I dared to touch the fuel engine."

Li Yi wants to eat seafood, the kind that is very fresh, not sent to death by freezing to death with ice.

It was sent to the place, and there was ice in it, but the crab was the live kind.

It requires only one thing, speed.

From Shandong, the railway will be built to Luoyang, and then the railway from Luoyang to Chang'an, the distance in a straight line is more than 1,000 kilometers, and the actual distance is more than 1,400 kilometers.

If the steam engine can run three stone kilometers in one hour, it can definitely reach the place in fifty hours.

Fifty hours, the crab can't die.

Why go to Shandong? Shandong is next to the sea, and at the same time, the Beijing-Hangzhou Grand Canal has to pass through that line.

Shandong belongs to the Henan Province of the Tang Dynasty, and Henan Road has always been the top priority.

"What's it for?" Li Chengqi didn't doubt that he could make it, he was thinking about the use.

"I'm trying to make a small one, tomorrow the propeller boat will be launched, big brother remember to come and see.

There was a problem with the counterweight ratio that I had made before, so I redid it.

If feasible, next year, the Jingzhaofu water network will not need to use ships, and the boats with propellers will be fast. ”

Li Yi frowned and said that he was worried about the steam train.

Even if the steam engine is built, what will happen to the rails?

How much iron is needed to lay more than 1,400 kilometers of railroad tracks? There's all that iron, and it's making guns.

There is still a shortage of kitchen knives in people's homes.

Make a smaller, not large-capacity rail, can the rails be wrapped in wood and iron?

Li Chengqi rarely saw Li Yi's distressed look, so he asked, "Brother Yi, but is there something difficult?" ”

"I use too much iron, wait a few months, and then I'll try to build a small children's train in Zhuangzi, steam, and you'll see it when you see it."

Li Yi thought of the small train in the park, which was actually electric, but it could be made into steam.

The weight of the steam head and the weight of the towed things, see if the small track will work.

……

The next day, Li Chengqi and Li Longji's family came.

When the little guy saw Li Yi, he showed a puzzled look, obviously he hadn't seen him for many days, and he had forgotten a little.

Li Yi didn't talk nonsense, put on life jackets for everyone, and went to Ba Shui.

The boat had been lowered from the dock on Zhuangzi's side, and the queen was holding her son, and the four of them sat on the pedal position.

The rudder is in the middle, and Li Yi controls it.

Everyone is familiar with pedals, and without the wheels on both sides, it seems a little unaccustomed.

"Ready, go." Li Yi was in charge of the temporary command.

With his order, the four of them kicked up together.

The tail propeller rotates, the stern splashes, and the initial speed is faster than all boats.

Even a ship is nowhere near as good as a propeller ship.

The ship itself is subjected to the resistance of the water due to the rotation of wheels on the left and right sides.

The oars of the propeller boat are underwater, and the front of the boat is pointed when the boat is designed.

The shape of the bottom of the boat is also different, with grooves that are used to divide the water.

The four of them pedaled quickly, and the speed of the boat gradually increased.

The rudder controlled by Li Yi began to be unstable, and it was not how the rudder swung to the ship, and the ship could immediately change direction, there was a process.

"Dragon boat, dragon boat, this is the speed of the dragon boat." Queen Wang felt it, and when the dragon boat was racing, the dragon boat was swishing and moving fast.

The boat that is sitting on it now has a speed similar to that of a dragon boat.

The boat of the dragon boat is narrow, needs a lot of people, and cannot maintain speed for a long time.

Pedal boats, apparently, can last longer.

"Good boat, good oars." Li Longji said.
