The next morning, Li Longji still had a slight fever. Li Yi did not give him any medicine.
He drank half a bowl of chicken and vegetable porridge and ate some salted vegetables before going to court. He took a thermos and a watermelon.
The thermos was filled with salt water. Watermelon was naturally watermelon. Other people did not have watermelons, but the Li Family Zhuangzi could still provide watermelons.
The watermelons from the south were ready, but distant water could not quench the immediate thirst.
After ten days, the watermelons from the capital government were ready. It just so happened that the Li Family Zhuangzi's watermelons were ready.
At court, the officials were discussing the war with Su Lu.
"Your Majesty, Su Lu led the Abbasid Caliphate and Tubo to attack. I think he should be reprimanded." The Minister of Rites stood out.
Li Longji looked at him and said, "No need, just beat him."
He was decisive. What was the use of reprimanding him? If you rebel, I will beat you. Do you think I am afraid of you?
If you force me into a corner, I will ask Brother Yi to bring the Winged Knights to capture you alive. Do you think I don't have a trump card?
"Your Majesty, please build more Hundred Stone Boats for the border." Su Yi stood out. He had discovered the benefits of boats.
"I have something to say …"
Li Longji began to talk about his canal to connect to the Yellow River.
… …
"This is the Pujin Crossing. Originally, there was a bamboo pontoon bridge. Now, it is replaced by a metal chain." Minister of Honglu Temple, Liu Tong, introduced it to the Japanese exchange team.
They came last night and saw the terraced fields planted by more than 220,000 surrendered households.
Today, after breakfast, they were going to Hukou Waterfall. When they passed by the metal chain pontoon bridge, Liu Tong explained.
"Liu-san, is that cement?" Abetaka Maru looked at the bridge and felt that it was useful. It was suitable for Japan.
"Concrete. There are steel bars, pebbles, and cement inside." Liu Tong explained in detail.
"Is Liu-san familiar with the method of making cement?" Abetaka Maru asked.
"I don't know. The Li Family Zhuangzi is keeping it a secret. Lantian County is under military control. Outsiders are not allowed to ask." Liu Tong looked at the people of the Japanese Empire.
The people of the Chamberlain of Dependencies already knew what Li Yi meant. Secrets that should not be leaked must not be leaked.
Moreover, he really didn't know how cement was made. Everyone who made cement only knew their own job.
The envoys from the Japanese Empire all had expressions of regret on their faces.
Of course, they understood why they had to keep it a secret. The construction of the city wall with cement was very fast. It would take a few days to build a city wall.
According to Takagi Junichiro, the Tang dynasty sent a lot of cement to the border to build a city there to defend against the enemy.
Liu Tong laughed in his heart and said, "The method of making it cannot be passed down. However, if you want to buy it, you can sell it. A catty of cement only costs one coin. "
He followed Li Family Zhuangzi's instructions to promote the cement. The Li Family Zhuangzi's base price was three catties of cement for one coin.
There was a small profit, which was 5%.
"Is it cheaper to buy more?" Shinbei felt that it was a little expensive. It was not that he felt that the cement was not worth the money, but that he needed too much and had to ship it back to Japan.
Liu Tong nodded. "Ten thousand catties, three catties of cement for two coins. One hundred thousand catties, two catties of cement for one coin. Five hundred thousand catties, five catties of cement for two coins."
He still didn't say the base price. All he knew was that if he wanted to build a city, it wouldn't be enough without a few hundred million catties of cement.
If the city was bigger, more cement would be used.
Building a house in the south of Chang 'an was a mix of cement and sand.
A normal house, according to Li Dongzhu's instructions, was ten feet tall, made of bricks, and had an area of 50 square meters. If he used it sparingly, it would cost 500 catties of cement.
If it was replaced with reinforced concrete, it would cost more than ten thousand catties of cement for the same height and area.
The difference was that big. It depended on which aspect you used the cement for.
Building houses now was the cheapest kind. Who would want reinforced concrete?
The reinforced concrete foundation by the river was forced. Adding up both sides of the river, more than 26 million catties of cement were used.
It was only that heavy, so it was naturally less used for plastering.
However, the price wasn't too high. It wasn't as expensive as iron chains.
Cement cost eight million catties, and eight thousand catties. Was that considered money? Reinforced concrete and iron chains were more than ten times the cost.
If it was replaced with iron, it would be more than a hundred times the cost. Fortunately, there was cement, which saved money.
Building a city required plastering. Otherwise, the amount of cement used …
The people of the Japanese Empire didn't know the situation. When they heard how many catties of cement, they felt that it was enough to build a lot of cities.
"Liu-san, 60 million catties, 20 million catties." Abeda Nakamaro gritted his teeth and bargained.
Liu Tong frowned and shook his head: "I can't make the decision. This price is too low. If I go back and ask, I will say that the Tang dynasty and the Japanese Empire are friendly. Let Li Dongzhu sell it even if it's a loss."
"Please, Liu-san." Abeda Nakamaro was very uncomfortable when he heard the words "Japanese Empire".
A few years ago, they also felt that the name "Japanese Empire" was fine. Later, they felt that it was discriminatory, so they changed it to "Japan".
However, the Tang dynasty called you the Japanese Empire. Even if you were unhappy, you had to accept it.
The others also bowed together, hoping that Liu Tong would help more.
In fact, this amount was only eighty thousand tons at Li Yi's time. What could eighty thousand tons of cement do?
They still had to ship it back. If it rained, the cement would be soaked by the rain …
Even if there was no rain, the sea was very humid, and the cement would be in contact with moisture …
"Everyone, let's get on the boat. It's not time to open the bridge yet. Let's go up. If we take the boat from above, it will take two and a half days to reach Hukou Waterfall."
Liu Tong invited 555 people to take the boat from here to Hukou Waterfall, which was nearly three hundred miles upstream.
It was already good enough to travel ten miles in two hours. If it was Li Yi's goose boat, they wouldn't be able to travel far even if they were exhausted.
Not to mention the goose boat, even an iron paddle boat would take more than ten minutes to travel two miles, and it was still on the Yellow River.
The Yellow River's current was fast, and it needed to offset some of the work.
If it was on the Yangtze River, it would be able to travel six miles in two hours, which was far faster than a boatman pulling a rope.
Of course, if it was a propeller and went against the Yellow River, it would definitely be more than thirty miles in two hours.
After passing through the turbulent areas, the speed could be increased to forty miles per hour.
If Li Yi were to bring out the steam engine …
If he made the diesel engine …
The Japanese felt that speed was good. They had already drawn a picture and written a description.
The picture they drew was different from Li Yi's. The difference was huge.
Li Yi drew a three-dimensional picture. When the Li Family Zhuangzi's craftsmen saw the picture, they knew what to do.
Everyone got on the prepared boat and pedaled by themselves. If they could change people, they pedaled with all their might. They wanted to test how fast it could go.
"Liu-san, I heard that there's another kind of boat that looks like flying." Fujiwara Ma Yang spoke at this time.
"Yes, there's another kind of boat from the Li Family Zhuangzi. It's faster than this." Liu Tong admitted.
They had envoys here. It was impossible that they didn't know about the amazing boat that day.
"Can you let me take a look? Bring it up for me to see. "Fujiwara Ma Yang requested.
Liu Tong shook his head. "No, it's a national treasure. Doctor Li won't agree. There's no need to think about it. It's useless to ask the prime minister or His Majesty."
"Not even His Majesty? Should he be beheaded? "Fujiwara Ma Yang said as if he was thinking for the sake of the Tang dynasty.
"Kill him and you'll make good things for the Tang dynasty? Do you know how many good things Li Dongzhu has made? Why would His Majesty agree to it? "
Liu Tong's face turned ugly. You still want to sow discord? Do you know the relationship between His Majesty and Li Dongzhu?
His Majesty can't wait to hold court in the Li Family Zhuangzi. It's safe and worry-free.
You're just an envoy from the Japanese Empire. Why are you so troublesome?
