When Zhangsun Xin came to the riverside, there were many people standing on the shore looking at the boat.
Compared to other boats, this boat was 20 feet long and about 40 feet wide.
There was a chimney on the top of the boat, and black smoke was gurgling out.
There were no oars, no sails, and no big wheels on both sides. It should be the kind of boat with propellers underwater.
But this boat was too big. How many people would step on it?
Also, the boat seemed to be made of iron, not wood.
"Fast, how fast can this boat go?" Li Longji stood on the deck of the boat in a good mood.
"It's faster than walking. It can run more than 20 miles in an hour. The fastest is 30 miles." Li Yi introduced.
Along the way, he introduced a lot of things, including the boiler, the pressure gauge, and how to weld the iron boat.
The pressure gauge used a spring tube, which was the simplest type. But it didn't need to be filled with silicone oil.
How did he measure the pressure of the spring tube? Didn't he exchange for a medical oxygen tank? That one had a pressure gauge.
He used that gauge to check and locate the current steam engine pressure gauge. After confirming it, he could make more.
The welding technology was a type of welding. It used acetylene and was made by himself.
Anyone who had the technology to make acetylene and calcium carbide could make steel. This was because the production of calcium carbide required a higher temperature than the melting temperature of ordinary steel.
Then, he used the acetylene made from calcium carbide and used the oxygen tank for welding. This way, the iron boat appeared.
He also made a water-proof cabin. Others saw the boat, but in fact, it reflected the technical foundation of the Li Family Zhuangzi.
With this boat, he could write a thesis and send it to other countries and foreign countries. After reading it, they still couldn't make it.
At present, the fastest speed of the boat could reach 17 knots. In this case, the pressure on the propeller shaft was too great, and it was easy to break.
Maintaining a speed of 12 or 13 knots was enough. It could run 22 kilometers in an hour.
If this boat went to America, it had to go through the Strait of Magellan because there was no Panama Canal.
It was like going to Africa without the Suez Canal to enter the Mediterranean Sea and had to go around the Cape of Good Hope.
From the Tang Dynasty to the west, before going to Africa, it had to go through the Strait of Malacca. When Li Yi came over, there was no Carat Canal, the one in Thailand.
In fact, if there were enough resources, it could go from the Cape of Good Hope directly to South America, across the ocean, and the Atlantic Ocean.
To the east was the Pacific Ocean. They arrived at Peru, Ecuador, and Chile.
After going around the Strait of Magellan, they would reach Argentina. Continuing up, they would reach Brazil. There were many good things here.
Corn, peppers, tobacco, everything was here. Silver and gold.
If it was a little off-topic, the cacti in Mexico were also quite good. They were big and could be roasted and eaten.
Of course, if they really went out to sea and headed east to America, they couldn't go there directly. They had to go a little further south.
The Philippines, Indonesia, Papua New Guinea, the Solomon Islands, Fiji, Tonga, the Cook Islands, French Polynesia, the Pitcairn Islands, Easter Island …
In any case, they had to visit all the islands along the way to replenish their water supplies.
If others wanted to go out to sea, they would have to risk their lives all the way. They might even end up in the Hawaiian Islands.
Li Yi had a map and marked out the coordinates of all the places where they could resupply.
The fleet had already considered which island to replenish their supplies to, so if they still couldn't pass, they would be idiots.
Theodolite, sextant, simple desalination equipment, and so on were all prepared.
This included fresh yellow rice wine in barrels. If there was really no water to drink, they would drink it.
They could even bring ice and saltpeter in the cabin.
Carrots, oranges, and Chinese medicine were equivalent to following the route and finding things to bring back.
There was no need for the people to search for the mines alone. They had marked out the location.
"How long will it take to get to the place you mentioned?" Li Longji realized the advantage of the steam engine ship. It could keep running.
"According to the math, half a month. Based on the actual situation, God knows.
In theory, a month should be about the same, but it will take a detour.
You won't be able to reach the other shore locally. If you travel by land, everyone will die. "
Li Yi wanted something, but he didn't send people to check it out.
Disembark from the West Coast and go through the Amazon rainforest? The Winged Knights couldn't accept it, even if they marked out the dangerous animals and insects in the area.
Not to mention the Amazon rainforest, even Hubei Shennongjia?
"In that case, can you go back and forth in three months?" Li Longji was anxious about the potatoes that Li Yi mentioned. He had eaten potatoes before and thought they were good.
"In the past, there might not be corn seeds, potatoes, sweet potatoes, and rubber trees. We have to bring back more this time. Gold and silver don't matter."
Li Yi was also anxious. He wanted to eat tomatoes and kidney beans. Kidney beans were beans and green beans.
Including some nuts and big apples. As for marijuana, it could be used for medicinal purposes.
Tobacco was fine, but if they brought it back to teach the people of the Tang dynasty to smoke tobacco pipes?
"Yes, gold and other things can't compare to the food of the people." Li Longji had also thought it through.
Money was not a problem. If they wanted money, they could find Brother Yi.
"When we come back for the first time, tell the big families and those who are willing to take the risk." Li Yi said casually.
"Give them benefits? Let them stay in the Tang dynasty? "Li Longji frowned. No one was willing to compromise.
"It's an excuse. When they go out, we set the rules. It's only convenient for us to take action when they break the rules." Li Yi smiled.
"Haha!" Li Longji suddenly laughed. He felt very comfortable.
In the eyes of the people, the Dongzhu of the Bashui Li Family Zhuangzi in Chang 'an was a very kind person.
The big families thought that Li Yi was indecisive and not ruthless enough in some aspects.
But in reality? Brother Yi acted for the sake of the Tang dynasty. There was no situation where he couldn't do it.
He could kill people in person and continue to live a normal life after killing.
The moment he smashed the enemy's head, the moment he returned to Zhuangzi, he could pick up the children, kiss them, and raise them up high.
Brother Yi didn't care about killing people. If he wanted to kill, he would kill.
Would killing a chicken make a psychological impact?
Brother Yi killed people like killing chickens.
"Brother Yi, can you kill children and pregnant women?" Li Longji suddenly asked.
Li Yi shook his head directly. "No, some people kill to train their courage. When they kill their own kind, they break the moral bottom line and the code of conduct.
My purpose for killing people is clear. You deserve to die. Your existence has seriously interfered with me, so I kill you, or you want to kill me.
Children and pregnant women are not a threat to me. What's the point of killing them? To prove to others that I'm cruel and cruel, so that others will be afraid of me? "
Li Yi always felt that the difference between humans and animals was that humans had their own judgment and bottom line.
Aboriginals killed people to eat. Humans could also eat. Civilized people killed innocent people. If the other party didn't threaten you, why would you do that?
When people killed innocent civilians to train their courage, then such people were not human.
